Replacing a new bulb will improve the brightness, but the service life of halogen lamp is not long. You can choose to refit the lamp, replace the xenon lamp or LED lamp. The working principle of halogen lamp is to inject halogen gas such as iodine or bromine into the bulb. At high temperature, the sublimated tungsten wire reacts with halogen, and the cooled tungsten will solidify on the tungsten wire again, forming a balanced cycle to avoid premature fracture of tungsten wire. When the filament is heated, the tungsten atoms are evaporated and move towards the glass tube wall. When approaching the glass tube wall, the tungsten vapor is cooled to about 800 ° C and combined with halogen atoms to form tungsten halide.
The solution to the problem of halogen headlight on:
1. The automobile halogen bulb contains halogen gases such as iodine or bromine. At high temperature, the sublimated tungsten wire reacts with halogen to produce light,
The color is yellow, showing a warm light color, relatively dark. If you want to improve the brightness of halogen headlight, you can only replace the brighter bulb. Relatively speaking
It is said that the brightest halogen bulb in the car is the high brightness halogen lamp, which can increase the brightness by 20%, better than ordinary halogen lamp and incandescent lamp;
2. Halogen lamp technology is mature, the light is more uniform and soft, strong penetration, and the internal structure is very simple, maintenance is very convenient, compared with ordinary incandescent lamp, longer life, the price is also relatively cheap. But there are also some disadvantages, that is, the use of high temperature, more power consumption, but the brightness is not high, which is also a lot of car owners are distressed. Want to thoroughly improve the overall lighting effect, can only choose to refit xenon lamp or LED
3. Xenon lamp is different from halogen lamp, it is activated by high voltage current xenon light source, color temperature, brightness, long service life and energy saving. L
LED is used as the light source of ED lamp, with high light quality, no delay, low energy consumption and long service life. However, the LED light has poor heat dissipation, so it must be equipped with scattered light
Heat exchanger can reduce the working temperature of the headlamp, and the cost of LED headlamp is high, and the refitting cost is expensive. It should be noted that the unauthorized modification of the car
The light may not pass the annual examination. For halogen lamp to be refitted into xenon lamp or LED lamp, lens needs to be added.
