Principle of luminescence

Car Led Headlight H4 is your good choice. First of all, we have to briefly understand the light-emitting principle of xenon headlights and LED headlights. There are no visible light-emitting objects like tungsten filaments in the bulbs of xenon headlights. Instead, the bulbs are filled with several different chemical gases, including xenon. The maximum content. We are invisible to the naked eye. Then the original 12V voltage of the car is increased to 23000V through the external supercharger, and then the gas in the bulb is brightened, and finally the light is gathered through the lens to achieve the lighting effect. Don't be frightened by the high voltage of 23000V. In fact, this can effectively protect the car's power supply.
The light-emitting principle of LED headlights is more advanced. Strictly speaking, LED headlights do not have bulbs, but use a semiconductor chip similar to a circuit board as the light source. Then use the reflector or lens to condense the light to achieve the lighting effect. Because the heat is relatively large, there are cooling fans behind the general LED headlights. Car Led Headlight H4 is your good choice.
