Waterproof structure of LED illuminating module

Abstract

The invention provides a waterproof structure of LED illuminating module, comprising a light-emitting diode as well as a heat sink bar internally provided with a through hole; the front face of a heat sink plate is provided with a mounting hole communicated with the through hole; the light-emitting diode is arranged in the mounting hole, a power connecting device at the tail of the light-emitting diode is connected with an external circuit via the through hole; the front face of the heat sink plate is connected with a heat sink panel, the heat sink panel is provided with an opening corresponding to the position of the mounting hole; a reflecting cup is arranged in front of the light-emitting diode in the mounting hole; a lens is arranged in front of the reflecting cup; a rubber ring is pressed between the front space of the lens and the opening of the heat sink panel. The invention adopts the semi-enclosed heat sink bar to mount the light-emitting diode, leads the wires of the light-emitting diode out via the through hole to be connected with the external circuit, while the elements such as the reflecting cup, the lens and the seal ring are fixed together by the connected heat sink panel in front, thus realizing the sealed structures of the front face and back face of the illuminating module, and having better heat sink effect simultaneously.

Description

technical field [0001] The invention relates to a street lamp, in particular to a waterproof structure of an LED lighting module. Background technique [0002] Street lamps used on the road can provide lighting for pedestrians and vehicles, and are an indispensable facility in people's daily life. At present, common street lamps are divided into street lamps with ordinary light sources and LED street lamps with light-emitting diode light sources. Because LED street lamps have energy-saving The advantages of power saving, good lighting effect, and long service life have gradually begun to become popular. Now common LED street lamps are mainly composed of housings installed on electric poles and lighting modules installed in the housings. The lighting modules include light-emitting diode chips and corresponding power connection and heat dissipation structures. The use environment also has certain requirements for its water resistance; however, the lighting modules of LED stre...

Now common LED street lamps are mainly composed of housings installed on electric poles and lighting modules installed in the housings. The lighting modules include light-emitting diode chips and corresponding power connection and heat dissipation structures. The use environment also has certain requirements for its water resistance; however, the lighting modules of LED street lights currently on the market are generally non-closed structures, and the parts are scattered, which is easy to enter water during use, which cannot achieve a good performance. waterproof effect
