Description

With the continuous development of science and technology, light source products are constantly innovating: from incandescent lamps to mercury lamps, to metal halide lamps, to sodium lamps (high voltage, low voltage), until now LED (Light Emitting Diode) semiconductors light. LED semiconductor lamps are getting more and more popular because of their long life, energy saving and environmental protection.

LED semiconductor lamps are generally composed of an LED light source, a heat sink, a reflector, and a lamp housing. The existing LED semiconductor lamp adopts a flat type of light, and the LED light source is a flat type LED light source, that is, a plurality of LED chips are soldered on a flat type substrate, such as a printed circuit board (PCB). The flat panel LED light source may be composed of a plurality of C 5mm low power LED chips, or the flat panel LED light source is composed of a plurality of medium power LED chips of 1W, 3W or 5W, or the flat LED light source is composed of a plurality of 10W, 20W. It is composed of a high-power LED chip, and the flat-panel LED light source, the heat sink, the reflector, and the lamp housing can be an integrated structure. Since the existing LED light source is a flat type, and the conventional light source is a cylindrical type, the existing flat type LED light source is difficult to be directly mounted into the conventional lamp housing, so the interchangeability with the conventional light source is poor, and if the LED light source is to be used, it must be replaced. With the traditional lamp housing, the cost of the renovation project is too high, which undoubtedly seriously affects the popularization of LED light sources.

Furthermore, LED chips and phosphors of LED light sources have a certain degree of light attenuation from physical properties. However, the current manufacturers of LED light sources do not consider how to make up for this defect from the application system. Therefore, after the LED light source works for a period of time, the light intensity emitted by it will be weakened, which will inevitably cause inconvenience to people. , affect the promotion of LED light source in the market.

In addition, since the LED light source for illumination belongs to a power type semiconductor device, a lot of heat is emitted during operation, and it is necessary to dissipate heat to the air in time. Otherwise, the temperature of the LED light source rises, the brightness quickly decays, and even the LED chip is damaged. , resulting in a reduction in the life of the LED light source. Therefore, the LED light source generally needs to adopt a heat dissipation structure design, usually using an aluminum substrate plus an aluminum profile heat sink, plus natural heat dissipation, air cooling heat dissipation or heat pipe heat dissipation, and also using a semiconductor refrigeration chip to dissipate heat. Use heat sink or

Confirmation The heat dissipation cost of the heat pipe is relatively high, and if the fan is used for heat dissipation, since the substrate of the LED light source and the light transmissive pipe are too close together, the wind is difficult to blow in, and the temperature of the LED light source cannot be lowered.
