LED lamp

Abstract

The invention belongs to the field of illumination, and provides an LED lamp. According to the LED lamp, LEDs are directly attached to the inner wall of a reflection cup, heat emitted by the LEDs is transmitted out in a heat conduction mode, the problem that the LEDs are poor in heat dissipation effect due to the fact that the bonding by smeared heat dissipation resin between an aluminum substrate and a radiator of an existing LED lamp is poor, and the service life of the LEDs is prolonged. In addition, heat dissipation grooves are formed in the cup wall of the reflection cup, therefore, the heat generated by the LEDs can be transmitted out through the reflection cup in the heat conduction mode and can also be transmitted out through the heat dissipation grooves in an air convection mode, and thus the heat dissipation efficiency of the LEDs is further improved. Further, the reflection cup is made to move back and forth in the axial line direction of the reflection cup by being rotated, the reflection cup can squeeze or not squeeze the opening of the reflection cup when the reflection cup moves back and forth in the axial line direction of the reflection cup, so that the opening of the reflection cup is made to become smaller or restore an original shape, and thus the light emitting angles of the LEDs are adjusted.

Description

technical field [0001] The invention belongs to the lighting field, in particular to an LED lamp. Background technique [0002] When the LEDs of the existing LED lamps are installed, the LEDs are first welded on the aluminum substrate, and then fixed to other components (such as the lamp body) by screws, and heat dissipation resin (such as silica gel) needs to be coated between the aluminum substrate and the heat sink. ) for heat dissipation, but the heat dissipation resin is often applied unevenly, which leads to poor adhesion between the aluminum substrate and the heat sink, which in turn leads to poor heat dissipation effect of the LED and reduces the life of the LED. In addition, the heat dissipation structure of the LED is not a one-piece structure, which wastes materials in terms of cost, and also costs three to four more materials in terms of management. Furthermore, the light emitting angle of the LED lamp cannot be adjusted. Contents of the invention [0003] Th...
