As a kind of mobile lighting tool, LED headlamps are often used in flammable and explosive situations. The working principle and advantages of LED headlamps will be specifically introduced here.
An LED headlamp is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The following is the working principle and advantages of the LED headlamp.
The working principle of LED headlamp
The heart of the LED is a semiconductor chip, one end of the chip is attached to a support, one end is the negative pole, and the other end is connected to the positive pole of the power supply so that the entire chip is encapsulated by epoxy resin. A semiconductor wafer consists of two parts, one is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, where electrons are the main ones. But when these two semiconductors are connected, a P-N junction is formed between them.
When the current acts on the chip through the wire, the electrons will be pushed to the P area, where the electrons and holes recombine and then emit energy in the form of photons. This is the principle of LED light bulbs. The wavelength of light is also the color of light, which is determined by the material forming the P-N junction.
Advantages of Led headlamp
1. Energy saving and environmental protection, the energy consumption of LED lights is 1/20 of that of halogen lights
2. Low cost and long life. The high-quality LED rechargeable headlamp can last up to 100,000 hours, which means that basically your car can't be driven, and it is still on.
3. The brightness is high, the brightness of the led rechargeable headlight headlamp is much higher than that of the halogen lamp, and the warning light used as the brake light has no pressure.
4. Low-voltage safety, the first LED element used in electronics, only needs a DC voltage of 12V to light up, and there is no need to worry about the voltage of more than 20,000 xenon.
5. Instantly light up, no longer need the xenon lamp "will be on again", just use it anytime.
6. A single LED is small in size, which is the favorite of designers. It can be assembled into all kinds of favorites, and it is the favorite of lighting manufacturers.
