LED lamp

Abstract

The utility model relates to an LED lamp, belongs to the technical field of illumination, and provides an LED lamp scheme combining a new structure and a new shape, an LED lamp body is formed by combining a heat dissipation lamp shell made of plastic and a sealing lining part in a sealing mode, heat conduction liquid is injected into a cavity formed between the two plastic parts, an LED light source circuit board assembly is installed on the bottom plane of the lining part, and the LED light source circuit board assembly is installed on the bottom plane of the lining part. Heat generated when the light source works is rapidly conducted to the surface of the lamp shell through heat conduction of the liquid and then dissipated into the air. In order to increase the heat dissipation surface area and enhance the heat dissipation effect, a plurality of heat dissipation grooves are formed in the surface of the lamp shell, the heat dissipation effect of the lamp shell is better than that of an existing popular plastic-clad aluminum lamp shell, the light attenuation speed of an LED light source is slowed down, the service life of the lamp is prolonged, waste lamp resources can be recycled and utilized more easily, the lamp is more environmentally friendly, the appearance design of the lamp is flexible and changeable, new product development is facilitated, and the market prospect is wide. And the method has obvious social and economic benefits.
