Xenon lamp is a new type of headlight containing helium, also known as high-intensity discharge gas lamp, short for HID Intensity Discharge Lamp. Xenon flash lamp consists of xenon bulb, variable pressure ballast and insulated wire, using special helium gas in super high The discharge is triggered in the voltage state. I believe many people are really confused about the xenon flash circuit . Fortunately, fortunately, now there is Duan Niang, any questions that do not understand can ask Du Yun Niang, slowly through the mother know the Xenon flash, and slowly understand the design principle of this flash circuit. So if you do not understand the principle of Xenon flash circuit , you may wish to follow me to understand it!
What is Xenon flash
Xenon lamp is a new type of headlight containing helium, also known as high-intensity discharge gas lamp, referred to as HIDIntensityDischargeLamp. The xenon lamp broke the principle of tungsten filament invented by Edison. The quartz lamp was filled with high-pressure inert gas, Xenon xenon, to replace the traditional filament. There were mercury and carbon compounds on the two electrodes, which passed through the ballast to 23000 volts. The high-voltage current stimulates the glow of the xenon, forming a perfect white arc between the two poles, and the light emitted is close to perfect sunlight.
Xenon flash circuit principle
Unlike traditional halogen lamps, automotive HID xenon lamps are high-pressure discharge lamps whose light-emitting principle uses positive and negative electrical stimulation to stimulate the reaction of xenon with rare metals. Therefore, there is a small glass ball in the lamp tube. It is filled with helium and a few rare metals. As long as the current is used to stimulate them to react chemically, both will emit light with a temperature of 4000K-12000K. It uses a special ballast that uses a 2V voltage from a car battery to generate a trigger voltage of 23,000V or more to start the lamp. The 0.8 second brightness at start-up is 20% of the rated brightness, reaches the brightness of the halogen lamp, and makes the headlights reach more than 80% of the rated brightness within 4 seconds. After the lamp stabilizes, the ballast provides about 80V supply voltage to the lamp to keep the lamp running at constant power.
Xenon flash performance benefits
1. A typical 55W halogen lamp can produce only 1000 lumens of light, while a 35W xenon lamp can produce 3200 lumens of bright light, a 300% increase in brightness, and a wide field of view with an extremely long and super wide angle, giving you unprecedented driving comfort. Feelings; let the night is no longer dark, clearer vision, can greatly reduce the rate of accidents.
2. HID Xenon lamp uses electron excitation gas to emit light, and there is no tungsten wire, so it has a long life of about 3,000 hours, which greatly exceeds the total number of hours of night driving. The halogen lamp is only 500 hours.
3. Power-saving: The xenon lamp is only 35W, and the light emitted by the 55W halogen lamp is 3.5 times lighter, which greatly reduces the load of the automotive power system, saves power loss by 40%, accordingly improves vehicle performance and saves energy.
4, color temperature is good: there are 4300K-12000K, etc., 6000K close to the sun, praised by the majority of users, while the halogen lamp is only 3000K, light color dark red.
5, constant output, safe and reliable: When the car's power supply system and battery failure, the ballast automatically shut down and stop working. (Comparison Table of Lumens, Color Temperature and Lifetimes for Xenon and Halogen Lamps)
Xenon flash brand introduction
Since Germany's BMW HID principle was published in 1991 ("HID" in English: High Intensity Discharge: High-Intensity Discharge Lamps), Philips has spent five years in development. In 1995, the new Mercedes-Benz E-Class sedan was first used in HID Xenon lamps. Today, more than 20 million vehicles worldwide have been equipped with Xenon lamps. It has been popular in Europe, America and Southeast Asia for more than six years. It is known as the revolutionary automotive lighting product in the 21st century. It is believed that it will become the necessary assembly for the automobile after the ABS brake system and airbag... ...
HID Xenon lamps enhance the brightness of the original car's halogen lamp by three times, have better color and color temperature, more penetrating power, more light, and more stable performance. It is favored by more and more global automotive conversion users. Xenon headlights are more popular in Hong Kong, and there are also HID Xenon lights installed in domestic cars such as the Audi A6, Passat 2.8V6 and Sonata 2.7. It is expected that in the next two or three years, the models of domestic vehicles equipped with xenon lamps will greatly increase. Experts predict that by 2008, the proportion of new cars equipped with HID Xenon lamps in Europe will reach 21% (4.8 million), and Japan will reach 40% (3.8 million). Xenon headlights will replace halogen lamps and will become a new trend in the 21st century.
The world's powerful car xenon lamp manufacturers can refer to the number of technology, has been represented by Europe, the commonly recognized brands in Europe are: PHILIPS, HELLA, EOS, OSRAM. The four products are stable in performance and pure in color. In addition, Panasonic in Japan is also relatively recognized, followed by the headlamps of Korean and Chinese Taiwanese manufacturers. The domestic manufacturer of xenon lamps is represented by Guangdong, China, among which the quality of the Longeite xenon lamps is the highest. Excellent, Long Jie Xenon lamp adopts HELLA (Hala) technology, the main components are imported from abroad, and the ballast is guaranteed for three years. It is the only xenon lamp that passed the inspection and certification by the Ministry of Public Security. The price of other brands is relatively low, but the quality is difficult to guarantee. The stability of the HID xenon lamp is mainly determined by the ballast components. The quality HELLA (Hella) occupies an absolute advantage, HELLA focuses on supporting the global car OEM, Sigma EOS Ballast is also relatively stable, mainly for the HID conversion market, so the EOS price is only 2/3 of HELLA, the original HID model is D2S/D2R, such as the Audi A6 xenon headlamps, modified models are: H1, H3, H4, H7 , H11, 9005, 9006, such as EOS Xenon headlight conversion series products.
Most of the current use xenon type flash (Xenon Photoflash). The triggering method is to use a high-voltage capacitor to store enough energy and then release its energy to the lamp. This energy will excite helium in the lamp to generate a light source. The energy required to trigger the flash is provided by a high voltage capacitor (typically about 200V to 300V) for storage. In hand-held products (such as digital cameras, mobile phones), how to efficiently and quickly store battery energy into high voltage capacitors depends on how the charging circuit is designed.
