Description

[0002] LED lamp is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of LED lamp is a semiconductor chip. One end of the chip is attached to a bracket. One end is the negative pole, and the other end is connected to the positive pole of the power supply. The whole chip is encapsulated by epoxy resin. LED lamp has the characteristics of high efficiency, environmental protection and long life. However, due to the high brightness of LED light, it is easy to convert light energy into heat energy, making the LED lamp very hot. At this time, if the LED lamp cannot dissipate heat as soon as possible, its life will be greatly reduced.

[0003] In the prior art, the heat dissipation structure function of the LED lamp used is relatively simple. Usually, a high-temperature adhesive heat sink is used on the internal structure to dissipate heat during the use of the LED lamp. This method not only has low heat dissipation efficiency, but also affects the internal temperature rise after long-term use, which is not conducive to long-term circulation and heat dissipation. It will not only significantly reduce the working performance of the LED, but also shorten the working life of the LED and affect its use. Utility Model Content
