2010年新瓷器时代-LED陶瓷散热方案1、前言瑷司柏电子为因应高功率LED照明世代的来临，致力寻求高功率LED的解热方案，近年来，陶瓷的优良绝缘性与散热效率促使得LED照明进入了新瓷器时代。

LED 散热技术随着高功率LED产品的应用发展，已成为各家业者相继寻求解决的议题，而LED散热基板的选择亦随着LED之线路设计、尺寸、发光效率…等条件的不同有设计上的差异，以目前市面上最常见的可区分为(一)系统电路板，其主要是作为LED最后将热能传导到大气中、散热鳍片或外壳的散热系统，而列为系统电路板的种类包括：铝基板(MCPCB)、印刷电路板(PCB)以及软式印刷电路板(FPC)。

(二)LED晶粒基板，是属于LED晶粒与系统电路板两者之间热能导出的媒介，并藉由共晶或覆晶与LED晶粒结合。

为确保LED的散热稳定与LED晶粒的发光效率，近期许多以陶瓷材料作为高功率LED散热基板之应用，其种类主要包含有：低温共烧多层陶瓷(LTCC)、高温共烧多层陶瓷(HTCC)、直接接合铜基板(DBC)、直接镀铜基板(DPC)四种，以下本文将针对陶瓷LED晶粒基板的种类做深入的探讨。

2、陶瓷散热基板种类现阶段较普遍的陶瓷散热基板种类共有LTCC、HTCC、DBC、DPC四种，其中HTCC属于较早期发展之技术，但由于其较高的制程温度(1300~1600℃)，使其电极材料的选择受限，且制作成本相当昂贵，这些因素促使LTCC的发展，LTCC虽然将共烧温度降至约850℃，但其尺寸精确度、产品强度等技术上的问题尚待突破。

而DBC与DPC则为近几年才开发成熟，且能量产化的专业技术，但对于许多人来说，此两项专业的制程技术仍然很陌生，甚至可能将两者误解为同样的制程。

DBC乃利用高温加热将Al2O3与Cu板结合，其技术瓶颈在于不易解决Al2O3与Cu板间微气孔产生之问题，这使得该产品的量产能量与良率受到较大的挑战，而DPC技术则是利用直接披覆技术，将Cu沉积于Al2O3基板之上，其制程结合材料与薄膜制程技术，其产品为近年最普遍使用的陶瓷散热基板。

可调光市电输入LED通用照明解决方案LED在电子系统中使用已经有很多年了，主要用作电子设备的指示灯。

最近在亮度和色彩深度方面取得的重大进步，意味著LED现在可以用于更广泛的应用，从手机和多媒体播放机中的趣味照明，一直到取代商业和家庭照明应用中的传统光源。

推动LED照明市场发展的关键推动力是高亮度LED和智能LED控制器的出现。

采用高亮度LED的产品设计师面临著许多设计挑战，包括散热管理、驱动方案、拓扑架构和已有的基础设施。

要替代现有的可调光白炽灯或卤素灯光源，必须实现这样的一个电子灯驱动系统，它不仅可以与现有的调光开关一起工作，而且可复制现有光源的调光性能。

NXP(恩智浦SSL2101 IC可以满足上述性能要求，此外，它还是一种高效的电源转换器。

这是业内第一款集成这些能力的IC，它使得高亮度LED灯/模块设计师能够以一种省成本和体积的方式集成电子电路，并从最佳热权衡中获益。

LED特性LED需要一个与白炽灯或卤素灯完全不同类型的驱动器。

白炽灯表现为具备自稳定特性的纯电阻负载，LED则需要一个电流源。

LED产生的光通量近似正比于流经该器件的电流。

LED的正向电压随电流增加而增加，但随温度的上升而减少。

在这方面，LED表现得象二极管。

不过，在工作期间LED的正向电压（VF）是很大的。

该电压与电子转化为光子时产生的能量（eV）相关，该能量又直接相关于光的颜色。

此外，不同生产批次之间的VF值可以相差很大。

串行/并行配置在大多数用LED替代现有光源的应用中，需要连接多个LED到驱动器上，因为单一的LED不能产生足够的光通量。

LED可以采用串行或并行连接。

如果LED采用串行连接，LED链上的总电压等于正向电压的总和（所有LED上的电流相等）。

如果LED并行连接，电流将分配到各支路中。

不过，由于一个LED的正向电压会随著温度上升而下降，因此这一配置本质上是不稳定的。

随着温度的升高，越来越多的电流将流到具有更低正向电压的支路上去，这些支路将变得更亮，而那些具有更高正向电压的支路将变得更暗。

2With higher effi ciencies than incandescent bulbs and without the hazardous chemicals found in Cold Cathode Fluorescent Lamps (CCFL, LED lighting is gaining popularity as an environmentally friendly lighting solution. The ability to control brightness and color temperature by electronic dimming makes LED lighting an appealing solution for many illumination applications ranging from mood lighting to video projection.LED Driver Design ConsiderationsNational has a diverse portfolio of constant-current regulators for driving LEDs. Regardless of type, size, or power, all LEDs work best when driven with a constant current since the LED color changes with small variations to driving current. Therefore, LED manufacturers specify characteristics such as the lumens, beam pattern, and color of their devices at a specifi c forward current (IF , not at a specifi c forward voltage (VF . Most power supply ICs are designed to provide constant voltage outputs over a range of currents, not to provide a constant current as needed for driving LEDs. Using a constant-current regulator is also better than using a resistor as a current source because, with a resistor, the current accuracy is directly impacted by the accuracy of the input voltage, the tolerance of the resistor, and variations to the number orOther challenges with driving LEDs depend on the LED confi guration. Placing all the LEDs in a series string ensures the exact same current fl ows through each LED. The driving circuitry for the series confi guration is simpli-fi ed due to guaranteed currentmatching, but the number of LEDs that can be driven off an output rail is limited. With an array of LEDs, every parallel LED string must be driven with the same current to obtain even brightness and color. This confi g uration allows many more LEDs to be driven off an output rail but also increases the driving circuitry complexity. Choose from National’s LED drivers for both parallel and series confi gurations with features such as built-in current matching, high effiSeries Topologiespositive (+ to negative (-.Advantage:Parallel TopologiesLpositive (+ to negative (-.Advantage:visit: /LED.F3+=For more information about National’s PowerWise products, visit /powerwise4For a complete list of LED Drivers, visit /LED5H igh-Brightness LED DriversLighting Management UnitsLED DriversFor a complete list of LED Drivers, visit /LED6OverviewLow-power LEDs are ideal for backlighting applications, especially in small- to medium-scale displays, because they are effi cient and easy to drive. For many portable applications, each low-power LED requires up to 4V at 30 mA from a lithium-ion battery that typically supplies 3.6V. To operate more than one LED for a lighting solution, a boost LED driver is required to supply enough voltage to forward-bias the LEDs and provide regulated current.In medium-scale displays such as laptops and GPS navi-gation devices, a boost regulator may also be needed to drive long, parallel strings of low-power LEDs. National’s inductive-boost regulators provide LED driver solutions that are highly effi cient and capable of driving high cur-rents. In this section, you’ll fi nd various types of boost LED drivers with different dimming interfaces to accommodate multiple LED backlighting applications.Switching regulators that are current-mode boost con-verters operating at fi xed frequencies of 1.6 MHz (“X” option and 600 kHz (“Y” option.The SOT-23 packaging and use of small inductors and capacitors result in the industry’s highest power density. The 22V internal switch makes these devices perfectfor boosting to voltages up to 20V.Protection is provided through cycle-by-cycle current limiting and thermal shutdown.

The device’s synchro-nous switching operation (no external Schottky diode at heavy-load, and non-synchronous switching operation at light-load, maximizes power effi ciency. True shut-down function by synchronous FET and related circuitry ensures input and output isolation. A programmable soft-start circuit allows the user to limit the amount of inrush current during startup. The output voltage can be adjusted by external resistors.Pack age: Low profi le 10-pin LLP (3 mm x 3 mm x 0.8 mmL M4510 Typical Application CircuitL M4510 – Synchronous Step-Up DC-DC Converter for White LEDs and/or OLED Displays7/LEDCurrent-mode boost converter offers two separate outputs: (MAIN is a constant-current sink for driving series white LEDs, and (SUB/FB is confi gurable as a constant-current sink for series white LED bias, or as a feedback pin to set a constant output voltage for power-ing OLED panels.When confi gured as a dual-output, white LED bias sup-ply, the LM3509 adaptively regulates the supply voltage of the LED strings to maximize effi ciency and ensure the current sinks remain in regulation. The maximum current-per-output is set via a single external low-power resistor. An I2C-compatible interface allows for indepen-dent adjustment of the LED current in either output from 0 to max current in 32 exponential steps.When confi gured as a white LED + OLED bias supply, the LM3509 can independently, and simultaneously, drive a string of up to 5 white LEDs while delivering a constant output voltage of up to 21V for OLED panels.Package: Low profi le 10-pin LLP (3 mm x 3 mm x 0.8 mmDual White LED Bias SupplyV IN =L M3509 Typical Application CircuitLM3509 – High-Efficiency Boost for White LEDs and/or OLED DisplaysThe LM3430 is a robust boost controller capable of very high duty cycles (>90%.

It features a very fl exible confi guration, allow-ing the user to choose digital (PWM or analog dimming control, set a dimming ratio of up to 4000:1, and drive 4 to 6 channels with over 100 total LEDs. The LM3432 also has open and short circuit protection for each channel.Maximum system effi ciency is achieved by connecting the Dynamic Headroom Control output of the LM3432 to the feedback input of the LM3430. This confi guration also enables the LM3432 to achieve optimal power dissipation and thermal performance.Package: LM3430: LLP-12 (3 mm x 3 mm LM3432: LLP-24 (5 mm x 4 mm x 0.8 mm, eTSSOP-28 (9.7 mm x 6.4 mm x 1.1 mmOXL M3430/LM3432 Typical Application CircuitL M3430 and LM3432 – Boost Controller and 6-Channel Current Regulator for LED BacklightingInductive-Boost Backlight LED Drivers83-channel linear current controller combined with a boost switching controller designed for driving LED backlighting panels in space-critical applications.

Eight LED driver current sinks are split into three independently controlled groups for multiple lighting features. The LM2756 has 32 exponen-tial dimming steps with an 800:1 dimming ratio digitally controlled by an I2C-compatible interface.Package: Low profi le 20-bump micro SMD (1.615 mm x 2.015 mm x 0.6 mmLM2756 Typical Application CircuitLM2756 – Multiple-Display LED Driver with I2C-Compatible Brightness ControlA constant frequency, pre-regulated, switched-capacitorregulator operates at 1.25 MHz to produce a low-noise regulated output voltage. The device can be confi gured to provide up to 100 mA at 4.1V, 110 mA at 4.5V, or 180 m A at 5V. Excellent effi ciency is achieved without the use of an inductor by operating the charge pump in a gain of either 3/2 or 2 according to the input voltage and output voltage option selection. The LM2757 presents a high impedance at the VOUT pin when shut down, which allows for application use requiring the regulated output bus to be driven by another supply while the LM2757 is shut down.A perfect fi t for space-constrained, battery-operated applica-tions, the LM2757 requires only four small, inexpensive ceramic capacitors. Built in soft-start, over-current protection, and thermal shutdown features are also included.Package: Tiny 12-bump micro SMD (1.2 mm x 1.6 mm x 0.4 mmLM2757 Typical Application CircuitLM2757 – Switched-Capacitor Boost Regulator with High Impedance Output in Shutdown*Bump D1 is (NC No ConnectSwitched-Capacitor Boost Backlight LED DriversOverviewThe presence of an inductor often contributes to the problem instead of the solution, especially in space-constrained, low-noise ap plications. National’s switched-capacitor LED drivers provide a small, inductor-less solution for both parallel and series LED confi gurations. In this topology, the input voltage connects to a multiple-gain switched capacitor that produces a regulated output. The switched capacitor remains in the mosteffi cient gain over the widest input voltage consumingthe least amount of energy through gain transitions thatmaintain regulation based on LED forward voltage and load requirements. Multiple-gain boost modes allow for the highest possible effi ciency over a wide input voltage range resulting in longer battery life. Following, you’ll fi nd switched-capacitor drivers, including some that feature low noise, making them ideal for EMI-sensitive applications.10An integrated low-noise, high-current, switched-capac-itor DC-DC converter with a regulated current source.With a fi xed frequency of 1.2 MHz, the device is capable of driving loads up to 700 mA.

LED: Light Emitting Diodes FACTS GUIDEA.D.COLA LIGHTING86 Worcester St. Natick MA 800-698-LITE2Lighting your home efficiently is continually becoming more popular. LED products are now available for every type of lighting. At A.D.Cola Lighting we understand that with this new technology finding the right product can be challenging. It is our goal to make this processeasy for you. Our LED commitment begins with carefully choosing and quality testing all of ourLED products and bulbs before bringing theminto our store. LED is continually changing. Wemake it a priority to educate ourselves on new innovations so you can feel confident when choosing LED products from our showroom.This facts guide will go over information and benefits of using LED products. We hope you enjoy learning more about LED.LED FACTS GUIDE3WHAT IS LED?TOP 5 BENEFITS OF LED1. LONG LIFELEDs have a long life, lasting on average up to 50,000 hours—longer than incandescent, halogen, and compact fluorescents bulbs. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. LEDs do not have a filament, instead they are made of solid state technology. They will not damage like a regular incandescent bulbs. Resistant to bumping, drops and even the weather make it the most durable type of lightbulb today. Unlike other bulbs that become hot or need to heat up in order to operate, LED lights are much better at withstanding elements such as electrical surges, making for the longest lifespan of any light bulb at this time. This means less bulb replacements and in turn, more savings in replacement costs!2. EFFICIENTLEDs are more efficient, using approximately 80% less wattage than incandescent bulbs.Because less electricity is needed to light an LED bulb, it converts to huge savings on utility bills for the average consumer. LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and compact fluorescent bulbs, which emit light and heat in all directions. For this reason, LED lighting uses light and energy more efficiently in many applications, for example, reflector bulbs. However, for an A-shape bulb, it requires special engineering to get the light to shine all around the bulb.43. COOLLEDs are cool to the touch because they don’t produce heat in the form of infrared radiation(IR) (unless they are IR LEDs). Incandescent bulbs and other sources become hot becausethey produce IR radiation, which heats the enclosures and surrounding of the bulb. LEDsdo not have IR radiation, which allows fixtures to be placed in locations where the heatwould be a problem, e.g. illuminating clothes and artwork, or even children in reach of hot lamps. Another benefit is how much extra money can be saved on the cost of cooling homes. It may not seem like light bulbs can make a difference in the temperature of a room,but in fact they can. This allows for even more savings on energy bills.4. GREEN & NON-TOXICLED lights are the greenest solution available on today’s markets. They are non-toxic and greener than other alternatives as they do not contain any hazardous chemicals, mercury,gases or metals. LED lights are 100% recyclable, helping to reduce your carbon footprint.Their long life means that one LED light bulb can save the material and production of 25 incandescent light bulbs. LED bulbs are the greenest lighting solutions today.5. FLEXIBLELED lighting is flexible in color and design. LED lights come in various colors, shapes and designs to produce creative solutions for both residential and commercial spaces. LEDscan be dimmed to change the mood in any room. A well-designed LED illumination systemcan achieve some dramatic lighting effects that influence not only the eye but create themood for any atmosphere. Most LED bulbs in use today are clear or white bulbs, availablein “cool” or “warm” white light. But LEDs are also available in colors—Red, Green, Blue (RGB). RGB give tremendous design options for LED lights. RGB LEDs can be combinedto form thousands of other colors. This works great for accent lighting using LED tape.This type of lighting was thought only to be used on exteriors and interiors of hotels and buildings, but now homeowners use them as an affordable design option.LED FACTS GUIDE5UNDERSTANDING LED LABELSThe Federal Trade Commission along with manufacturers have developed a new label to help consumers when purchasing the energy-saving bulbs. It looks similar to nutrition labels on food and will contain important information about the bulb’s output and savings (see example below).The labels will include:• Brightness (Lumens),• Estimated Yearly Energy Cost• Life• Light appearance• Energy Usedeach is explained below:BRIGHTNESS (LUMENS)Lumens measure the amount of light produced, whereas watts measure the amount of energy required to light products. Simply put, the more lumens in a light bulb, the brighter the light. Lumen measurements are needed when comparing LED bulbs to other light sources. We now need to rethink how we measure light. Shopping by lumens will be more important than shopping by watts when choosing which LED bulb will work best. The chart below shows the lumens values for common incandescent bulbs:Watts Lumens40-watt incandescent bulb450 lumens60-watt incandescent bulb800 lumens100-watt incandescent bulb1600 lumens It’s important to note that lumens are measured at the source. However in directionalbulbs, what matters is the amount of light that is landing on the surface…LUMENS & DIRECTIONAL LAMPS. While lumens can be a guide to measure directional lamps, they do not tell the full story. Directional lamps are measured by the amount of light that gets to the surface you are lighting. This measurement is called footcandles. Directional lamps can come in different spreads—flood, narrow flood, and spot, to name a few. The light that is on the surface will look very different depending on the spread, but the lumen output can the same. Most LED bulbs to this point do not have a footcandle measurement on the box, but we can help determine the best bulb for your situation.6ESTIMATED YEARLY ENERGY COSTEstimated yearly energy costs is included on the label to show approximately how muchthis bulb will cost you to operate per year. It is expressed in dollars and based on the average initial wattage, a usage rate of 3 hours per day, and 11 cents ($0.11) per kWh.LIFE EXPECTANCY OF THE BULBThe life of each lamp is included on the label. It is expressed in years rounded to the nearesttenth (based on 3 hours operation per day).LIGHT APPEARANCEThe color temperature is expressed as “Light Appearance” on the label. The light appearanceis usually described as “Warm White” or “Cool White.” This is measured in degrees Kelvinon a scale ranging from 2,600 K to 6,600K. Warm white is a lower kelvin temperature, giving a softer feel to a room- good for family rooms, living rooms, and bedrooms. A coolwhite is a higher kelvin temperature, giving a whiter brighter light- great for kitchens andtask areas. When choosing what is best for you, consider your environment and the moodyou want to convey.The following is a guide to various color temperatures:• Warm White: typically from 2600 Kelvin to 3500 Kelvin• Natural White: typically from 4000 Kelvin to 4500 Kelvin• Daylight White: typically from 5000 Kelvin to 5500 Kelvin• Commercial or Cool White: typically above 6000 KelvinENERGY USEThe wattage for each lamp is listed on the label and expressed as “Energy Used.” Thelower the number the less energy it uses. Replacing a 60 watt incandescent bulb with an equivalent LED bulb will be typically 9.5 watts energy used.LED FACTS GUIDE7ENERGY STAR LOGOProducts that comply with ENERGY STAR regulations will display the energystar logo on its packaging. LED bulbs that have earned the ENERGY STAR aresubject to very specific requirements designed to replicate the experience youare used to with a standard A-type bulb, so they can be used for a wide varietyof applications. Click here to see more information on Energy Star products. COMPARE LED TO OTHER LIGHT SOURCESLED lights differ from incandescent, halogen, and compact fluorescent lighting in several ways.They are more efficient, durable, versatile and longer lasting. Incandescent and halogen bulbs uses a wire filament that is more sensitive to breakage making their life shorter (1-3 years). They also require more electricity to reach it’s brightness. Compact fluorescents, although last longer than incandescent bulbs, have many disadvantages. They do not have an instant-on, causing it to flicker and heat up before reaching full brightness. They contain mercury which complicates their disposal. LEDs use light emitting diodes to produce light very efficiently. Electrical current passes through semiconductor material, which illuminates the tiny light sources we call LEDs. Many LED bulbs look like familiar traditional light bulbs making it easy to find replacement for your current bulbs. Some LED light fixtures may have LEDs built in as a permanent light source. For these fixtures, when the bulb goes out you need to replace the entire fixture. However, many of these fixtures have up to a 50,000 hour life expectancy.DIMMINGYes, you can dim LED! However, they do dim differently than incandescent bulbs. You must first choose the appropriate dimmer for your LED light. LEDs can flicker, or dim unevenly if you use the incorrect dimmer. Manufacturers specify which dimmers are compatible with their products.With incandescent dimming the color temperature will warm as you dim, some LEDs do not warm as they dim. If this is important to you , when choosing LED you must look for “warm dim”otherwise the bulb will dim in intensity only, not in color.8INTEGRATED OR REPLACEMENT LAMPSLEDs bulbs are available for almost all incandescent and halogen light sources, making iteasy to retrofit your existing fixture with LED ... just change the bulb. However when doingso, you have to consider several factors. 1. If you use a dimmer for your light sources,you must make sure it is compatible with the LED bulbs. 2. LED bulbs come in a varietyof lumens and color temperatures depending on the manufacturer. This could be an issue when you have multiple light sources that need to emit the same light. 3. For enclosed fixtures it is important to check that the bulb is rated for use in an enclosed fixture. Some manufacturers do not rate their bulbs for enclosed fixtures so using the incorrect bulb can result in a premature failure of the bulb.Choosing an integrated LED light fixture is becoming more popular. This means that the LED module is integrated in the fixture, making for a consistent light source in lumens, kelvin temperature and CRI. These fixtures usually have a long life of typically 50,000 hours. It is important to check on the life span and warranty when purchasing an integrated light fixture. Popular integrated light fixtures include recessed, under cabinet, decorative, and landscape lighting.LED FACTS GUIDE9IMPORTANT FACTORS WHEN CHOOSING LEDLUMENS. To replace existing fixtures or bulbs you must understand the equivalence of wattage to lumens. This is important to continue the same brightness. Most packaging will show the equivalence from wattage to lumens. e.g. typically 9.5 watts LED is equivalent to60 watts incandescent. Keep in mind, directional bulbs, with the same lumens can producea different amount of light at the surface depending on the spread of the bulb.COLOR TEMPERATURE or light appearance. The color temperature of a bulb will create the mood in a room. LED color temperature defines the amount of pure white, yellow, red and blue in a light. Color temperature is measured in degrees Kelvin. Another way to think of the color temperature is how ‘warm’ or ‘cool’ the white LED light is emitted. A “warm”color (similar to incandescent) is great for a family room or bedroom, and a “cool” color (similar to halogen) for a kitchen or work spaces.CRI: Color Rendering Index. CRI is a measure of how well light sources render the colors of objects, materials, and skin tones and surfaces. The CRI measurement determines the ability to show object colors “realistically” or “naturally” compared to the source of incandescent light or daylight. It is rated on a scale from 1-100. The higher the CRI rating, the better accurately colors will be reproduced.WARRANTY. As with any product that has a long life, check the warranty and what it covers. LED products usually come with a warranty rated by years or hours. LED bulbs and integrated LED fixtures may carry different warranties.10PLACES TO USE LEDIt is becoming easier to find great quality LED fixtures of all types for your home or office.For existing fixtures, making the switch is easy by replacing the current bulb with the rightLED bulb.Using LED has become very popular in rooms where you may leave the lights on for extended periods of time, like kitchens, family rooms, bathrooms, and finished basements (where lights are sometimes forgotten about!)LEDs are perfect for places that are hard to reach or fixtures that are difficult to change bulbs, including recessed and track, shower lights.Because LEDs are cool to the touch, they are great for under cabinet, closets, and hall/step lights.Outdoor is an ideal place for LED, both decorative and landscape lighting benefit usingLED.1. For it’s efficiency—many of us leave outdoor lights on for hours.2. For it’s instant-on—compact fluorescents need to heat up before full brightness, LEDhave an instant-on to full brightness, even in cold weather.3. For it’s “no bug” attractions—Bugs are attracted to ultra violet light, as this is the onlylight in the spectrum their vision can detect, much like the light produced by the sun.Unlike LEDs, both incandescent and fluorescent lights give off ultra violet light. Bugsare also attracted to heat, since LEDs do not produce heat, bugs are not attracted to it. THE COST OF LEDLED is still a new technology, so producing a quality product can make the expense fairlyhigh. Luckily, pricing has come down dramatically in the past several years and prices are expected to continue to drop. Because of this, it has made LEDs a cost effective choicefor home lighting. Considering whether LEDs are worth the extra up front cost, you needto look at the cost to operate a bulb in addition to the savings of replacement costs. The energy savings realized by switching to LED means that the extra up-front cost is oftenpaid back rather quickly, and you’ll wind up saving money over the life of the bulb.LED FACTS GUIDE11VISIT OUR LED CENTERA.D.Cola Lighting created an interactive LED center to educate you on the variety of ways youcan use LED lighting in your home.

IntroductionCommercial buildings and office buildings were recognized as the highest party of energy consumption of presenting buildings. The total annual energy use in office buildings lies in the range 100–1000 kWh/m2 yr, depending on the differences of location , operational schedules, use of HVAC systems, the use and type of office equipment, type of envelope, type of lighting, etc. (Santamouris & Dascalaki. 2002:575). For example, in Northern Europe, office energy consumption almost lies in the range 269–350 kWh/m2 yr and for the offices all over Europe, it was about 306 kWh/m2 yr, with mean electric index 150 kWh/m2 yr and mean fuel index 158 kWh/m2 yr (Lagoudi & Loizidou et al, 2009:237). Recently, Stengard (2009) point out a record of energy use in Swedish commercial buildings of different age founded that the energy intensity of commercial buildings accouted as 210 kWh/m2 yr in average, and as highas 93 kWh/m2 per square meter witch not included heating.The nearby 2010 Energy Performance of Buildings Directive (EPBD) places a high demand on building professionals to produce or retrofit office buildings to near-zero energy use levels. According to previous research by Poirazis et al (2008:1161), modern office buildings have a high energy savings potential. Electric lighting is a huge area where energy savings are possible at reasonable invest in new buildings as well as in retrofit programs. Mean while, one recent study carried out by Enkvist (2007:155) indicated that electricity use for lighting could be reduced by 50% using existing technology and investments in energy-efficient lighting is one of the most cost-effective ways to reduce CO2 emissions.This article will explores the significant potential for energy savings in commercial building lighting, and exam the capable Improvement of energy saving for electric lighting base on exiting technology.2. Literature Review2.1 IntroductionThis literature review will give literacy about the huge actual energy use in lighting through the example of electricity consumption by existing commercial buildings, and point out the significant part of electric demand can be reduced by using existing technology. Then, shows achievement about the available technologies with analyze result of efficiency in electricity saving; costs effective and reliability. At last summarize the effect of thosetechnologies and the potential saving achievement by adapting those technologies over the world.2.2 Actual energy use for lighting.Globally, lighting is an important area in reducing overall energy consumption (Hanselaer et al, 2007:171). In Sweden, for example, lighting accounts for around 10% of total energy consumption in the country, and this area still have quite a lot potential for energy savings (Govén et al, 2002:87). In commercial buildings, lighting constitutes generally 20–45% of electric lighting can sometimes up to 40% per cent of total energy consumption(Traberg et al, 2005:06). The most significant environmental impact (80–90%) of lighting is produced when running the lighting system; Electric lighting installation costs usually represents the total cost of only 15%, while electricity use during operation reached around 70% of total costs (Svensson,Ed,2010). In Sweden,Non-residential electricity consumption for lighting typically accounts for 25-30%. (Stengard,2009). The recent inventory of 123 office buildings of varying age by the Swedish Energy Agency Exposed an average energy intensity of 21 kWh/m2 yr for office lighting and an average installed lighting power density (LPD) of 10.5 W/m2, which depending on the room type:: 13.1 W/m2 for individual office rooms, 12.4 W/m2for landscape offices, and 8.6 W/m2for common rooms (including corridors). Note that office electric lighting was 30 kWh/m2 yr in Sweden in 1990; It can be seen that a reduction of around 9 kWh/m2 yr has occurred in 20 years (Hanselaer et al, 2007:180). Average LPDs of 7–11 W/m2is achievable using efficient lamp circuits (based on T8 i.e. 26 mm fluorescent tubes andstandard electronic high frequency ballasts) for general office lighting of 300–500 lx (Loe, 2003:52). If theimprovement in Sweden can be applied world widely, it can be greatly slow down the speed of global warming by reduce the CO2 emissions form lighting.2.3. Energy saving potential for commercial building lightingAccording to Borg (2009:89), an existing office (in Sweden) uses around 23 kWh/m2 yr for electric lighting, compare to that it may only use 11 kWh/m2yr by using a modern advanced installation. If occupancy and daylight sensors are integrated in the installation, the annual energy consumption for lights may decrease to as low as 5 kWh/m2 yr.Recently, Bülow-Hübe (2008:61) investigated the daylight availability and electricity use for lights in offices located in Gothenburg, Sweden, by simulations using the validated programs Rayfront/RADIANCE and DAYSIM. The study included three different façades (30, 60 and 100% window-to-wall ratios) of single-cell and open-plan offices. Assuming a LPD of 12 W/m2, if the lights were switched on 9 h/day, 5 days/week, then annual electricity use for lighting was calculated to be 28 kWh/m2yr. Assuming manual light switching, the electricity use obtained could dropped to 20–23 kWh/m2yr with a mix of active and passive users. furthermore, lighting electricity use obtained was in the range 11–18 kWh/m2 yr, if using a perfectly commissioned photo sensor dimming system, and mixed users. Thus, this study demonstrated by simulation that compare to a case with manual on/off switch near the door, it is possible to cut down electricity use for office lighting by about 50% (from 23 to 11 kWh/m2 yr) by using existing technology.In other countries, Santamouris et al. (1994:59) reported the findings of a large monitoring campaign in 186 office buildings in Greece, where the specific energy consumption of the buildings for heating, cooling, and lighting purposes, as well as the consumption for office equipment were monitored. The data for electric lighting showed average energy use ranging from 15 to 25 kWh/m2yr depending on type of building. Around 50% of the buildings presented a lighting consumption inferior to 11 kWh/m2 yr while for the majority of buildings (86%), the consumption was less than 20 kWh/m2 yr.Also worth noting: besides direct electricity savings due to reduced use of lights, indirect energy savings can also be obtained because of the reduced heat production and cooling needs (Hanselaer et al, 2007:180; Athienitis&Tzempelikos, 2002:271). However, in cold climates, there might be an increase in energy use for heating, which is likely to be smaller than the electricity savings. The next section examines the strategies to execute in order to reach such low energy intensity.2.4 Existing technology to reduce energy use for lightingStrategies to reduce energy use for electric lighting in offices include:1) Strategies directly related to the electric lighting installation:1.3.1 LED application in lighting.LEDs have becoming the most suitable candidate replacing traditional fluorescent lamps because of its energy-efficient, the introduction of high brightness LEDs with white light and monochromatic colors have led to a movement towards general illumination(Guan et al 2008). This revolutionizes the optoelectronics market, enabling engineers to use LEDs for general lighting applications as well as medical, indoor lighting and automotive solutions. So variable LED array modules were developed, they are making great strides in terms of lumen performance and reliability, however the barrier to widespread use in general illumination still remains the cost or luminous efficiency, special requirements concerning optical properties and opt mechanical layout have to be met. In order to meet the requirements of indoor illumination, a LED daylight lamp model was designed, it can replace traditional fluorescent lamp without insteading additional power supply establishment.1.3.2 Improvement in ballast technologyIn the past, ballasts were relatively simple wire-wound devices and consumed an appreciable amount of energy – typically 10–20% of the lamp wattage (Loe, 2003:54). Modern ballasts however often use electronic circuits. High frequency (HF) electronic control ballasts, which can be used with both T8- and T5-tubes, use less than half the energy required by the conventional wire-wound types (Energy Saving Trust, 2006). Inefficient ballasts are being steadily phased out across the European Union following the adoption of the Ballast Directive 2000/55/EC. Since November 21, 2005, only low loss magnetic ballasts with typical efficiencies of 85% (depending on the lamp power)and high frequency electronic control gear with efficiency values more than 92% are allowed (Hanselaer et al, 2002 :90).Recent statistics carry out by Richards&Carter (2009:258) for Sweden indicate that fluorescent tubes with HF-ballasts, with T8 and T5-tubes, represent so far only 27% of the total installed lighting power density in offices in spite of the fact that HF ballasts have existed for 20 years. HF lighting has many advantages: an improved lighting quality, flicker-free lighting, and reduction in power demand, compatibility with occupation sensing and daylight control, better controllability and longer life.1.3.3Using hybrid lighting systems (not finish)Hybrid systems simultaneously deliver daylight and electric light into a building where they are combined and distributed via luminaries. Hybrid technology is described together and that of the more established of tubular daylight guidance lighting systems. Likely system performance in terms of daylight delivery and potential electricity savings are evaluated for representative geographic locations throughout the world.1.3.4 Strategies related to daylight harvesting:Papamichael (2006:208) claims that most commercial spaces have enough daylight next to windows to eliminate the need for electric lighting (apart for buildings located in the far north of Scandinavia where there is hardly any daylight in the winter). The exploitation of daylight, commonly referred to as ‘daylight utilization’ or ‘daylight harvesting’, is recognized as an effective means to reduce the artificial lighting requirements of nondom estic buildings. Daylightutilization may allow energy savings compared to electric lighting due to its higher luminous efficacy. For a given quantity of illumination, light from clear blue skies delivers the least amount of heat gain (Mardaljevic et al, 2009:261).Effect of latitude and orientation; Effect of window characteristics;Effect of shading devices; Effect of reflectance of inner surfaces;Effect of ceiling height;Effect of partition height.In Reinhart(2002:01) open-plan office study, it was also shown that lowering partition heights from 64 in. (162.6 cm) to 48 in. (121.9 cm) nearly doubled energy savings for the automated and manually controlled blind scenario. Another benefit of reduced partition heights between peripheral and second row offices was that the latter get a partial view outside. On the other hand, lower partitions reduce the acoustical separation between two work spaces. A smart design option might be to group work places that require intense communication betweenco-workers in peripheral and second row offices and reserve inner spaces with higher partitions for more noise sensitive tasks, as proposed by the author. Another solution might be to use transparent or semi-transparent partitions.Summarize of technologies and strateg iesConclusion。

This energy waste can be minimized with the help of SpaceWise Technology. Traditionally, some spaces in a manufacturing facility are configured to stay on all the time, wasting a significant amount of energy. With SpaceWise Technology it is possible to reduce this energy waste by dimming the lights to a background level during unoccupied periods.• Luminaires, or entire defined zones, that detect motion brighten to 100%, and dim to a 20% background level five minutes after motion ceases.• Luminaires, or entire defined zones, that do not detect motion remain dimmed at a 20% background level.• The entire luminaire group will turn off if no further motion is detected for an additional five minutes.• Luminaires that detect motion brighten to 100%, and dim to a 20%background level five minutes after motion ceases.• Luminaires that do not detect motion remain dimmed at a 20%background level.• The entire luminaire group remains at a 20% background leveluntil motion is detected againSpaceWise technology may be integrated with emergency luminaires to provide appropriate light output during emergencies while still reducing energy use during normal conditions. A built-in battery pack can be incorporated to save energy, or alternatively, the ‘path of egress’ setting can be activated for luminaires on an emergency generator circuit to disablethe luminaire’s automatic shutoff during emergencies. It is not necessary to create a separate group of luminaires on the emergency circuit, however, care should be taken to identify those on the circuit and activate their ‘pathof egress’ setting.• Luminaires that detect motion brighten to 100%, and dim to the appropriate background level after motion ceases for the mode-specific period of time.• If battery pack is specified, the lights will turn off after the mode-specific period of time.• Luminaires with the activated ‘path of egress’ setting will not automatically turn off and will stay at the background level while the remaining luminaire group will behave per the specified mode.Control and illuminate the path to egressTools and Tech SpaceWiseThe SpaceWise Remote is necessaryto configure the SpaceWise System.The remote is used to group up to 50luminaires together and to activatethe automated dimming behaviorsby choosing the proper applicationmode within the space.
