Detailed analysis of xenon flash lamp circuit

The xenon flash circuit is really confusing to people like me who have never seen the world. What exactly is a xenon flash? What role does it play for us? Fortunately, there are With Du Niang, you can ask Du Niang any questions you don’t understand, so I personally prefer Du Niang. The editor slowly learned about the Chaqi flash through Du Niang, and gradually learned about the design principle of this flash circuit. So if you don’t know about Chaqi flash, just follow the editor and I will take you to understand.

What is a xenon flash lamp?

The xenon lamp is a new type of headlight containing xenon, also known as a high-intensity discharge gas lamp, and its English abbreviation is?HID?Intensity?Discharge?Lamp. The xenon lamp breaks the tungsten filament light-emitting principle invented by Edison. The quartz lamp tube is filled with high-pressure inert gas - Xenon? A high-voltage current of 23,000 volts stimulates xenon gas to emit light, forming a perfect white arc between the two poles, and the light emitted is close to perfect sunlight.

Xenon flash lamp circuit principle

Car? HID xenon lamp is different from traditional halogen lamp. This is a high-pressure discharge lamp. Its light-emitting principle is to use positive and negative electricity to stimulate xenon and rare Metal chemical reactions emit light, so there is a small glass ball inside the lamp, which is filled with xenon and a little rare metal. As long as current is used to stimulate them to undergo a chemical reaction, the two will emit as much as ?4000K-12000K? color temperature of light. It uses a special ballast and uses the 1.2V voltage of the car battery to generate a trigger voltage of more than 23,000V to start the light. The brightness for 0.8 seconds at startup is 20% of the rated brightness, reaching the brightness of a halogen lamp, and allows the headlights to reach more than 80% of the rated brightness within 4 seconds. After the lamp is stable, the ballast provides approximately 80V supply voltage to the lamp to keep the lamp running at constant power.

What are the advantages of a bifurcated gas flash lamp

1. The general 55W halogen lamp can only produce 1000 lumens of light, while the 35W xenon lamp can produce 3200 lumens. Lumens of strong light, brightness increased by 300%, with ultra-long and ultra-wide-angle wide field of view, bringing you unprecedented driving comfort; making the night no longer dark, the field of vision is clearer, which can greatly reduce the rate of driving accidents.

2. ?HID? The halogen lamp only has ?500? hours.

3. Strong power saving: xenon lamps only have 35W, but emit 3.5 times more light than 55W halogen lamps, which greatly reduces the load on the car's power system and saves power consumption. ?40%?, correspondingly improving vehicle performance and saving energy.

4. Good color temperature: 4300K-12000K, etc., 6000K is close to daylight, and is well received by the majority of users, while halogen lamps are only 3000K, and the light color is dim and red.

5. Constant output, safe and reliable: When the car's power supply system and battery fail, the ballast automatically shuts down and stops working. (Comparison table of lumens, color temperature and lifespan of xenon lamps and halogen lamps)

Summary: In fact, the bifurcated gas flash lamp is a new type of lamp. Relatively speaking, this kind of lamp will receive more attention because it has many advantages. The gas flash is more environmentally friendly and energy-saving. Regarding this kind of flash circuit problem, in fact, the editor, a physics idiot, still doesn’t have that much understanding. But I believe you are a smart person, and you can better understand the circuit design of the flashlight. I hope the editor’s introduction to the Chaqi flash light will be helpful to you.
