英文250W high pressure sodium lamp electronic ballast inductance ballasts and comparative analysis of performance and energy-savingHigh-pressure sodium lamp is a high intensity gas discharge lamp, and its development began in 1955. Now, high-pressure sodium lamp life of up to 10,000 hours, light efficiency is higher than 100 lm / W. High-pressure sodium lamp work issued gold white light, it has a high luminous efficiency, low power consumption, long life, transparent fog ability and so on. Is widely used in roads, highways, airports, terminals, stations, squares, industrial and mining enterprises, parks and other venues lighting. High-color high-pressure sodium lamp is mainly used in sports centers, exhibition halls, casinos, department stores and hotels and other places lighting, is widely used.The following pairs of commonly used high-pressure sodium lamp of 250W inductive and electronic ballasts for performance and energy efficiency were analyzed.First, performance comparison1.Their own power. 250W Ballast power consumption of about 22W,and with the output power increases. 250W electronic ballast power consumption of about 12W, and basically a constant value. Electronic Ballast own low power consumption, low temperature, the system efficiency.2. With the benchmark light with the light effect. Ballast with the benchmark light, its luminous efficiency is about the base and the base lights with light ballast efficiency 0.95% -0.98%. Of high frequency electronic ballasts because the current lighting, its photoelectric conversion rate is slightly higher than the inductive ballast. Another self-power small electronic ballast, making it the benchmark light after the light efficiency is about supporting the base and the base lamp ballast with 110% optical efficiency.3. Lamp life. Ballast is very difficult to start the feature is fully consistent with the lamp start-up requirements. When the input supply voltage variations and lamp aging, the lamp power fluctuations over large areas, greatly shorten the lamp life, increase the routine maintenance costs. Electronic ballasts can directly control the lamp current, in smaller start-up current, shortening the lamp start-up time. In a wide range of supply voltage variations and lamp aging, maintains constant lamp power, reducing the lamp light decline, thus greatly extending lamp life, reduce routine maintenance costs.4.Input power voltage range. On the inductance ballast, lamp power supply voltage fluctuations with the input change. When the supply voltage is high, the lamp of serious super-power (when the input voltage to 250V,some inductance ballast output power up to 380W or so), ballasts and light fever severe, greatly reducing the lamp and the lamp life. The electronic ballast with constant power output. In a wide range of supply voltage changes, be able to maintain a constant lamp power, reducing the lamp light decline, thereby significantly extending the life of lamps and lighting.5.Strobe lights problem. Due to AC 50Hz (or 60Hz) power network voltage zero-crossing of the impact of inductance ballast to produce low-frequency strobe light and produce a clear exchange of noise, easily lead to the human eye fatigue, but also moving objects can not meet the high quality of lighting and photography requirements. The high-frequency electronic ballast using high frequency electric current output lamp, high power factor boost circuit, in the middle with large-capacity DC-link filter, no low-frequency flicker problem, there is no low-frequency noise.资料来源：360毕业设计网订做论文 6. Peripheral attachment. Ballast need to activate the device and the compensation capacitor is not easy to install, reduce overall system reliability. The electronic ballast does not require any attachments, easy installation.7.The installation of ballast and light source distance requirements. High Pressure Sodium Ballast generally use an external trigger pulse, the distance between the ballast and the lamp short, unable to meet the long-term driving requirement. The high-frequency electronic ballasts using sliding-frequency lighting, electronic ballasts and the distance between the lamp can be extended to 50 meters, to facilitate ballast installation and routine maintenance.8. Harmonic content and power factor. Ballast input current waveform for the square wave and the current lags behind the voltage, input current harmonic content, it is not added when the power factor compensation capacitor is only about 0.6. Even with compensation capacitors, power factor is also very difficult to achieve 0.95or more harmonic content remains high. This has resulted in Ballast serious pollution of the grid, increase network load and increase connection fees. The high-frequency electronic ballasts with power factor correction circuit inside, so that the input current harmonic content of less than 10%,power factor is higher than 0.95,the grid basically no pollution, can reduce grid load, lower initial installation fee to use can also be used on the original inductance ballast lighting system directly compatibilizer.9. Electromagnetic compatibility problems. In addition to the low input current harmonic content, the electronic ballast can fully meet EMI and EMS requirements, thereby enhancing the reliability of the entire lighting system.10. Self-protection issues. Ballast can not be achieved to protect themselves, when the tube emerged "Rectifier effect" and near the end of life, there will be bright lights frequently, eliminate, resulting in greater loss of ballast, temperature increase. Electronic ballasts can achieve full protection against lamp open, light-side short-circuit, heat lamp, rectifier effect and the light end of life phenomena such as the blockade of electronic ballast output.11. Size and weight. 250W Ballast weight of close to 5 kg, were heavy and bulky raw materials consumed by many pairs of lamps and installation of components requiring high strength. 250W electronic ballast weight of only 1 kg, small size and easy installation.From the above analysis we can see that was significantly higher than the performance of electronic ballast inductance ballasts, electronic ballasts canfully meet the "green light" requirements, are environmentally friendly, energy-saving products.Second, comparative analysis of energy-saving1. Magnetic Ballast with full power constant output electronic ballast.(1) Inductance Ballast: Rated input voltage 220V, input power 272W, output power of 250W.(2) The full power constant output electronic ballast: Input voltage 220V, input power 262W, the output power of 250W.Comparative analysis of energy-saving: The power output the same circumstances, the use of electronic ballasts can save 10W of input power, energy-saving rate was 3.7%. If the grid voltage is increased, energy-saving electronic ballasts will be greatly improved.For example: power voltage of 250V,at this time Ballast input power 350W, electronic ballast input power of 262W,would save 90W of power, energy-saving rate of 30%.2. Inductance Ballast and low-power constant output electronic ballast(1) Inductance Ballast: Rated input voltage 220V, input power 272W, output power of 250W.(2) low-power constant output electronic ballast: For energy conservation, to extend the lamp life, while ensuring that illumination, electronic ballasts can be reduced to 80% of the output of the power output. This is, electronic ballasts rated input voltage of 220V,input power 210W,the output power of 200W.Comparative analysis of energy conservation: the use of such electronic ballasts can save input power 62W,energy saving rate of 23%. If the grid voltage is increased, energy-saving electronic ballasts will be greatly improved.For example: power voltage 250V, power of difference for the 350W - 210W = 140W, energy-saving rate of 50%.3. Inductance Ballast and automatic timing Dimming Electronic Ballast(1) Inductance Ballast: Rated input voltage 220V, input power 272W, output power of 250W.(2) In order to extend the lamp life, and further energy efficiency, while meeting the general requirements of road lighting, electronic ballasts can be reduced to the maximum output power of 80% of rated power, while at night will further reduce the power output ballast .Dimming electronic ballast strategies can be formulated according to the user's requirements, a maximum of dimming can be achieved grade 8.[For example, dimming strategy]Electronic ballast to work 12hours every night, rated input voltage of 220V. The implementation of three-dimming electronic ballast Strategy: 18:00 to 22:00 at night and 80% power output, input power 210W, output power 200W; at 22:00 to 4:00 am the next day and 50% power output , input power 134W, output power 125W; the next day 4:00 am to 6:00 am at 80% power output, input power 210W, the output power of 200W.Comparative analysis of energy conservation: the use of such electronic ballast, an hour every night could save an average input power 100W,energy-saving rate was 36.6%. If the grid voltage is increased, energy-saving electronic ballasts will be greatly improved.From the above analysis, the use of such automatic timing dimmable electronic ballasts, average power of 172W, working 12 hours a day, saving more than 1.2 degrees Ballast. In accordance with electricity 0.8yuan / kWh, 0.96yuan per day to save electricity. Through energy conservation, about a year to be able to fully recover the cost of electronic ballasts.中文250W高压钠灯电感镇流器和电子镇流器性能分析高压钠灯属于高强度气体放电灯，其发展始于1955年。

The installa-tion of the two wire bus is according to the appropriate low voltage regulations.switchDIMIntegrated switchDIM function allows a direct connection of a push to make switch for dimming and switching.Brief push (< 0.6 s) switches ballast ON and OFF. The ballasts switch-ON at light level set at switch-OFF.When the push to make switch is held, PCA ballasts are dimmed. After repush the PCA is dimmed in the opposite direction.The switchDIM fade time is set to 3 s from min. to max. in the factory settings. With a 20 s push to the push to make switch this fade time can be changed to 6 s. In this instance the switchDIM application will be synchronized to 50 % light level after 10 s and after 20 s the light level rises to 100 % with the new fade time.At every synchronizsation (10 s keystroke) the device will reset to 3 s (factory setting)In installations with PCAs with different dimming levels or opposite dimming directions (e.g. after a system extension), all PCAs can be synchronized to 50 % dimming level by a 10 s push.Use of push to make switch with indicator lamp is not permitted.Deactivation: If the corridorFUNCTION is wrongly activated in a switchDIM system (for example a switch is used instead of pushbutton), there is the option of installing a pushbutton and deactivating the corridorFUNCTION mode by five short pushes of the button within three seconds.switchDIM and corridorFUNCTION are very simple tools for controlling ballasts with conventional momentary-action switches or motion sensors.To ensure correct operation a sinusoidal mains voltage with a frequency of 50 Hz or 60 Hz is required at the control input.Special attention must be paid to achieving clear zero crossings.Serious mains faults may impair the operation of switchDIM and corridorFUNCTION.Backwards compatibilityWith a simple key combination a PCA TCL ECO lp x can be reset as a normal PCA ECO from the previous generation. Synchronisation simply has to take place three times within one minute (3 x 10 s).

This value is influenced by the way the wiring is made. Lamp connection should be made with symmetrical wiring.Hot leads (9, 10, 15, 16) and cold leads (11, 12, 13, 14) should be separated as much as possible.When using two or more dimmable ballasts in one luminaire with separate dimming controls, the lamp leads must be kept separate.Dimmable ballasts from Tridonic have to be earthed.Installation instructionsWiring type and cross sectionThe wiring can be solid cable with a cross section of 0.5 to 0.75 mm² for push terminal and 0.5 mm² for IDC terminal. For the push-wire connection you have to strip the insulation (8–9 mm).Loosen wire through twisting and pullingwire preparation:Intelligent Temperature GuardThe intelligent temperature guard protects the PCA TCL ECO lp x from thermal overheating by reducing the output power or switching off in case of operation above the thermal limits of the luminaire or ballast. Depending on the luminaire design, the ITG operates at about 5 to 10 °C above Tc temperature.Intelligent Voltage GuardIntelligent Voltage Guard is the name of the new elec-tronic monitor from Tridonic. This innov ative feature of the PCA family of control gear fromTridonic immediately shows if the mains voltage rises above certain thresholds. Measures can then be taken quickly to prevent damage to the control gear.• If the mains voltage rises above approx. 305 V (voltage depends on the ballast type), the lamp starts flashing on and off.• This signal “demands” disconnection of the power supply to the lighting system.corridorFUNCTIONActivation: To activate the corridorFUNCTION a voltage of 230 V simply has to be applied for five minutes at D1, D2. The unit will then switch automatically to the corridorFUNCTION.Deactivation: If the corridorFUNCTION is wrongly activated in a switchDIM system (for example a switch is used instead of pushbutton), there is the option of installing a pushbutton and deactivating the corridorFUNCTION mode by five short pushes of the button within three seconds.The corridorFUNCTION V2 offers the added benefit of a second and third preprogrammed profile, which can be activated by the corridorFUNCTION plugs.Application and functionallity of profiles see user manual.Operating voltageTypeWattage U out PCA 1x55 TCL ECO lp X 1x55 W 250 V PCA 2x55 TCL ECO lp X2x55 W350 VBallastTerminalMaximum capacitance allowed TypeColdHot Cold Hot PCA 1xx TCL ECO lp X11, 129, 10200 pF 100 pF PCA 2xx TCL ECO lp X11, 12, 13, 149, 10, 15, 16200 pF100 pFP HA SE D OU TRFI• Connection to the lamps of the hot leads must be kept as short as possible• Mains leads should be kept apart from lamp leads (ideally 5–10 cm distance)• Do not run mains leads adjacent to the electronic ballast • Twist the lamp leads• Keep the distance of lamp leads from the metal work as large as possible• Mains wiring to be twisted when through wiring • Keep the mains leads inside the luminaire as short as possibleGeneral adviseElectronic ballasts are virtually noise free.Magnetic fields generated during the ignition cycle can cause some background noise but only for a few milliseconds.For further technical information please visit PCA TCL ECO lp X 1x36–58 WPCA TCL ECO lp X 2x36–58 WDimmable ballasts from Tridonic have to be earthed.* * * leads 9, 10: keep wires short, max. 1.0 mleads 11, 12: max. 2.0 m; ballast must be earthed * * digital signal (DSI) or switchDIM* ** leads 9, 10, 15, 16: keep wires short, max. 1.0 mleads 11, 12, 13, 14: max. 2.0 m; ballast must be earthed* * digital signal (DSI) or switchDIMOperation on DC voltageOur ballasts are construed to operate DC voltage and pulsed DC voltage.To operate ballasts with pulsed DC voltage the polarity is absolute mandatory.Isolation and electric strength testing of luminairesElectronic devices can be damaged by high voltage. This has to be considered during the routine testing of the luminaires in production.According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A, each luminaire should be sub-mitted to an isolation test with 500 V DC for 1 second. This test voltage should be connected between the interconnected phase and neutral terminals and the earth terminal.The isolation resistance must be at least 2 MΩ.As an alternative, IEC 60598-1 Annex Q describes a test of the electrical strength with 1500 V AC (or 1.414 x 1500 V DC ). To avoid damage to the electronic devices this test must not be conducted.P HA SU。

电子镇流器简介电子镇流器因其显著的节能效果，体积小、重量轻、高可靠性，已经在紧凑荧光灯、日光灯、一体化灯等广泛应用，取得良好的经济效益和社会效益，随着电子技术不断发展，电子元器件可靠性不断提高，而成本大幅度降低，HID灯电子镇流器将成为绿色照明工程的重要部分。

HID灯（高强度气体放电灯）是目前国际上广泛使用的新一代高效光源，去年仅我国生产的金属卤化物灯泡、高压钠灯多达1480万只，而且随着基础建设不断加大，HID灯的用量每年都会有较大的增长，因此合理设计配套HID灯用的电器附件是非常重要的，而使用电子镇流器可以取得很好的性能价格比，以下本文就主要的几个方面介绍电子镇流器的性能特点与应用，并对如何进一步推广使用HID灯电子镇流器提出探讨意见。

二、电子镇流器的主要优点1、具有显著的节能效果，这主要的是：※在同等条件下，要得到相同的照度，相对于传统电磁式镇流器，使用HID灯用电子镇流器，其输入功率普遍可减少10%以上，因为灯泡采用高频或低频方波电流点灯工作时，其系统发光效率得到提高。

※电子镇流器自身的损耗小，我公司生产的250W电子镇流器效率可达92%以上。

※功率因数高，可达0.99，提高发电厂供电能力并降低输电线路损耗。

※由于电子镇流器具有稳定的灯输出功率（我公司生产的电子镇流器，电源电压变化±15%时，灯输出功率变动小于3%）,而使用电抗式镇流器的灯输出功率会随电源波动超过10%以上，因此，在设计时，为保证在电源电压波动范围内满足设计照度，均按电压波动的下限（-10%）设计，这样在正常电压使用时，灯从电源取得的输入功率将超过正常功率约10%，既造成灯泡过载，缩短灯寿命，也造成不必要的浪费。

但是，如果使用电子镇流器，由于电子镇流器有稳定输出功率的特性，不存在此类问题，达到同样的设计效果时，其从电源输入的功率可以降低10%以上。

以上可见，电子镇流器的节电效果是非常显著的。

2、可以大量节省资源从所周知，传统的电磁式镇流器需要消耗大量的矽钢片和漆包线，这将消耗大量存量有限的地球资源，如采用电子镇流器就可以大大降低资源损耗，以400W金属灯（电感镇流器）为例，需要铜2.0公斤，矽钢片4.0公斤，而使用电子镇流器，只需要铜约0.4公斤，不需要矽钢片。

1——受试镇流器2——基准镇流器3——基准灯在测量灯的功率时，对功率表的损耗不作补偿。

应将不使用的仪器短路或关闭。

将灯从一个镇流器安全快速地转换至另一个镇流器的方法尚在研究之中。

图1 高压汞灯用镇流器的试验线路表1镇流器的短路电流与标称工作电流之比三、开路电压当镇流器在其额定电压的92 %～106 %之间的任一电压下和额定频率下工作时，它所提供的电压不应小于IEC 60662中相应灯的参数表所给出的灯的启动试验电压。

110V与220V节能灯电子镇流器的设计关键字:EB（电子镇流器或电子安定器），倍压电路。

通常设计110V的EB比220V的EB难度要高点,尤其是高功率因数的,下面以几副常规的原理图引领大家进入文章的主题.图1 220V通用线路图2 100-110V倍压线路图3 100-110V直接驱动线路A图4 100-110V直接驱动线路A为何110V的EB比220V的EB难度要高，最直接的影响是灯的启动问题，尤其是整灯在高温低压时，容易出现灯管不能成功启动，只有两边灯丝发红。

原因是在高温时磁环和三极管的驱动能力降低，以至灯启动电压和灯启动电流供应不足而不能使灯管成功引燃。

灯启动电压和启动电流供应不足也影响低温低压时灯的启动。

另外，要想EB输出相同的功率，110V的EB的输出电流自然要比220V的输出电流大一倍，输出电流受控的关键点是EB的输出电感（也称扼流圈），此电感的选值太大，输出功率不足。

选值太小，便会引至EB的工作频率严重超标，三极管的开关损耗会上升，引至管子发热。

在线路的拓朴上,以上四副原理图是一样的,都是串联谐振正反馈电路，只是有一些巧妙的地方和元器件的数值选取不同。

此电路的最佳工作状态，必须符合：式1式中：Fw为工作频率。

Fo为整个谐振电路的固有频率。

以简单的词语说明就是：工作频率与输出电感和谐振电容的固有频率要相等，电路才能工作于最佳状态，此时负载电路等效于一个电阻，可提高整个EB 的效率，降低热损耗，整机性能上升。

图1是常规的220V原理图，图2是110V经过倍压的原理图。

图3为110V双谐振电容直接驱动原理图，图4是双谐振电容与灯丝交叉的直接驱动原理图。

图1不适宜用在110电路当中，何解？是因为要维持确定的功率，输出电感L2必须选得很小，要符合上式，谐振电容C6将要选取得很大，而C6不能选取得太大，因为太大了，启动电压将降低。

原因是：设有一高频电流流过灯丝，C6增大，等效于C6的电阻减小，C6两端的电压便下降，输出电感和灯丝的压降便上升，C6两端的电压下降，等于灯管电压下降，便很容易出现前文所述的高温不能启动问题。
