Destroying and consuming a lot of earth's energy, the earth's energy is also in crisis. Therefore, in addition to the development of new energy sources, countries that used to use power-hungry light bulbs are gradually replacing them with power-saving LED lights. In order to achieve a certain brightness, when a higher power LED lamp is used, it will generate high temperature, and this high temperature will not only affect the luminous efficiency of the LED lamp, but also damage the LED lamp and reduce its service life.

Most of the LED lamps currently on the market are covered in a confined space because the LED light source part is covered, and the heat source of the LED light source part and the circuit board is first conducted to the inner end of the heat dissipation fin, and then the heat is conducted to the external heat sink. Fins, and then conduct heat exchange with the outside air, but this heat dissipation method is not efficient, which in turn affects its luminous efficiency and service life.
