LED (Light Emitting Diode) illumination module

Abstract

The invention discloses an LED (Light Emitting Diode) illumination module. The LED illumination module comprises a heat radiator and a plurality of LED light emitting modules which are fixed on the bottom wall of the heat radiator, wherein each LED light emitting module comprises a lens and an LED aluminum base plate arranged between the lens and the heat radiator; the LED aluminum base plate is provided with LED light sources which are in series and in parallel; a first channel, a second channel and a plurality of heat radiation fins are arranged at the back part of the heat radiator; a lead wire is returned from the second channel to enter the first channel; a waterproof connector is arranged at one end, close to the bent part of the lead wire, of the first channel; a waterproof end cap is arranged at the other end of the first channel; the heat radiator is provided with a plurality of through holes which extend to the bottom surface of the heat radiator from the first channel and correspond to the LED light emitting modules one by one. According to the LED illumination module, the connection relation of the LED light emitting modules is changed, and one lead wire penetrates through the through holes to connect the plurality of LED light emitting modules in series, so that a wire arrangement and wire threading manner can be extremely simplified and the whole volume of the LED illumination module is reduced; the LED illumination module has the extremely good waterproof performace.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED lighting module. Background technique [0002] LED lighting technology is now being more and more widely used in household and public lighting occasions due to its advantages of energy saving, safety and environmental protection, long service life, fast response speed, and high luminous efficiency. [0003] Generally, the lighting modules are installed in the lamp holder of the street lamp in an embedded manner, and then the lighting modules are respectively powered through the wires of the lamp holder, so that the light-emitting components emit light. The structural design of the existing lighting modules is unreasonable, which leads to messy wiring in the lamp holder, which is not conducive to the reduction of the overall volume, and when installing the wiring, it is necessary to cut and connect the wires many times, which is time-consuming and laborious. In addition, the waterproof...

AI Technical Summary

Problems solved by technology

The existing lighting modules have unreasonable structural design, which leads to messy wiring in the lamp holder, which is not conducive to the reduction of the overall volume, and when installing the lines, it is necessary to cut and connect the wires many times, which is time-consuming and laborious

In addition, the waterproof performance of existing lighting modules is also insufficient, especially for outdoor street lamps, which often cause water leakage and cause street lamps to burn out.
