LED module

Abstract

The invention relates to an LED module. The LED module comprises a heat dissipater, a protection assembly, a light distribution lens and lamp beads, wherein the heat dissipater, the protection assembly and the light distribution lens are sequentially attached and fixed together; a plurality of rows of light-distributing curved surface grooves are formed in the surface, close to an aluminum PCB, of the light distribution lens, the distance between the light-distributing curved surface grooves is reduced from the middle to the two ends of the light distribution lens, and the lamp beads are arranged in groove bodies of the light-distributing curved surface grooves; and the heat dissipater comprises heat dissipation fins and a heat dissipation base, the heat dissipation fins comprise inverted-fishbone type heat dissipation fins and flat plate type heat dissipation fins, the heat dissipation fins and the heat dissipation base are of an aluminum extruding and integral forming structure, and the widths of roots of the heat dissipation fins are gradually reduced in the heat dissipation direction. According to the LED module, the service life of the LED module can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of energy-saving lighting, in particular to an LED module. Background technique [0002] With the development of society and economy, roads have become an important artery in economic development, and their demand is increasing day by day. At the same time, as a green lighting product in road lighting—LED lights, it highlights the advantages in road lighting. [0003] In the related technology, the LED module mainly includes a radiator, an aluminum PCB board, a protective rubber ring, and a light distribution lens arranged in sequence from top to bottom, wherein, lamp beads are installed on the light distribution lens to emit light, and the radiator includes a base and a light distribution lens. A plurality of heat dissipation fins are arranged parallel to each other and vertically on the heat dissipation base. The heat generated by the lamp beads during the lighting process is transferred to the heat dissi...

AI Technical Summary

Problems solved by technology

[0004] However, due to the fixed size of the heat dissipation base, the density of the heat dissipation fins on the heat dissipation base is relatively high, thereby reducing the heat dissipation effect

In addition, after the height of the heat dissipation fins is increased, the heat conduction path from the bottom of the heat dissipation fins to the top is high, so the heat dissipation effect is not ideal.
