Problems solved by technology

Specifically, the heat generated by the LED chip comes out of its metal heat sink, first passes through the solder to the PCB of the aluminum substrate, and then passes through the heat conduction glue to the aluminum heat sink. There are too many interfaces to pass through during the heat conduction and heat dissipation process, which affects heat radiation

Description

technical field [0001] The invention belongs to the technical field of LED lamps and relates to an LED lamp with high heat dissipation performance. Background technique [0002] The heat dissipation of LEDs is now more and more valued by people. This is because the light decay and lifespan of LEDs are directly related to their junction temperature. If the heat dissipation is not good, the junction temperature will be high and the lifespan will be short. [0003] The reason why the LED heats up is that not all of the added electrical energy is converted into light energy, but part of it is converted into heat energy. The light efficiency of LED is currently only 100lm / W, and its electro-optical conversion efficiency is only about 20-30%, that is to say, about 70% of the electric energy is turned into heat energy. [0004] Many manufacturers now integrate many LED grains together to obtain high-power LEDs. The power of this LED can reach more than 5W, and most of them appear...
