Background

The LED lamp is an electroluminescent semiconductor material chip, is solidified on the bracket by silver colloid or white colloid, then is connected with the chip and the circuit board by silver wires or gold wires, and the periphery of the LED lamp is sealed by epoxy resin to protect the internal core wires, and finally is provided with the shell, so that the LED lamp has good anti-seismic performance. LED (LightEmittingDiode) a light emitting diode is a solid state semiconductor device capable of converting electrical energy into visible light, which can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a support, the other end is a negative electrode, and the other end is connected with the positive electrode of a power supply, so that the whole wafer is encapsulated by epoxy resin. The semiconductor wafer is composed of two parts, one part being a P-type semiconductor in which holes are dominant and the other being an N-type semiconductor in which electrons are dominant. But when the two semiconductors are connected, a P-N junction is formed between them. When current is applied to the wafer through the lead, electrons are pushed to the P area, electrons and holes are combined in the P area, and then energy is emitted in the form of photons, which is the principle of light emission of the LED lamp. And the wavelength of the light, i.e. the color of the light, is determined by the material forming the P-N junction. The LED may directly emit red, yellow, blue, green, cyan, orange, violet, white light. The LED lamp greatly reduces the power required by illumination, the power required by the LED lamp with the same wattage is only 1/10 of that of an incandescent bulb, and meanwhile, the LED has the advantages of long service life, environmental protection, no maintenance and the like, and rapidly replaces the position of the incandescent bulb. The LED lamps are widely used, such as automobile lamps.

In cold winter, the existing automobile LED lamps generate fog due to larger temperature difference between the inside and the outside of the headlight, so that the indication effect and the illumination effect of the headlight are weakened, the illuminance is very low, and a certain traffic hidden trouble is increased in use.
