Description

[0002] LEDs have been widely used in various fields, with advantages such as long service life and soft light. However, LEDs generate a lot of heat, especially the LED chips, so LED lamps generally require a heat sink.

[0004] However, current heat dissipation lamp holders generally have grooves and raised structures on the side of the aluminum lamp holder that contacts the air to increase the contact surface with the air and improve the heat dissipation effect. However, since it relies on natural heat dissipation, the air in the groove expands after being heated, resulting in a decrease in the air contact rate of the lamp holder. In rooms with low air flow, the heat dissipation effect is not ideal. Utility Model Content

The bottom of the LED light strip 3 contacts the lamp holder body 1 to realize heat conduction. After the heat is introduced into the lamp holder body 1, it contacts the air through the first fin 5 and the second fin 6 at the bottom to realize heat dissipation.
