Description
Technical Field

[0002] LED lighting lamps are generally composed of a substrate, an LED light source with a driving power supply on the substrate, a heat sink and a lampshade. At present, LED lighting products are gradually replacing traditional lighting fixtures and becoming mainstream lighting products. For high-power LED lighting lamps, the level of light efficiency is a key factor, and the heat dissipation of LED lamps is a crucial factor in achieving long life and high light efficiency.
[0003] The luminous efficiency of high-power LED lighting is generally only 15% to 30%, and most of the remaining energy is converted into heat energy. If this heat cannot be effectively discharged, the temperature of the LED chip will increase. Working at high temperature will often cause the chip to fail, which will in turn shorten the service life of the lamp.
[0004] However, the heat dissipation method of existing high-power LED lighting is as follows:
[0005] 1. Generally, natural air cooling or forced air cooling is used for heat dissipation.

[0006] 2. To improve the heat dissipation effect, the surface of the lamp housing is generally used for heat dissipation. However, there is air between the heat dissipation substrate of the LED chip and the lamp housing to isolate the heat transfer. When the ambient temperature is high, the heat dissipation effect will be greatly reduced, resulting in a decrease in the service life of the LED lamp or even burning.
