Large-power LED light source module

Abstract

The invention relates to a large-power LED light source module comprising large-power LEDs welded on an aluminum substrate. A transparent lampshade is fixed to the front of the aluminum substrate, and a radiator is fixedly arranged at the back; and an LED driver is fixed to the other end surface of the radiator and is electrically connected with the aluminum substrate by a lead. The invention integrates necessary devices, such as the LEDs, the aluminum substrate, the radiator, and the like, provides convenience for subsequent application, particularly simplifies the design, the production and the assembly of the lamp manufacture industry, forms a uniform and standard criterion, brings convenience for repairing, is suitable for developing and applying indoor lighting products and is more suitable for the illumination field of outdoor engineering lamps with high power requirements, such as street lamps, spot lights, tunnel lamps, and the like, thereby providing the light source module with energy saving, high efficiency, waterproofness and good radiation performance.

Description

Technical field: [0001] The invention belongs to the field of lighting sources, in particular to a high-power LED light source module with heat dissipation effect. Background technique: [0002] It is a trend to replace traditional light sources with high-power LED light sources. Its non-filament structure has the characteristics of long life, low energy consumption, and small size. It is increasingly used in civil, industrial, and urban lighting fields. However, due to its small size and high brightness, it leads to concentrated heat generation, so the heat dissipation of high-power LED light sources becomes a necessary element. Existing high-power LED light source modules mainly include LEDs and aluminum substrates. The electrodes of the LEDs are directly welded on the aluminum substrates, and the larger aluminum substrates provide heat dissipation. In order to improve the overall brightness, more LED illuminants are often integrated on the same aluminum substrate to form...

AI Technical Summary

Problems solved by technology

In order to improve the overall brightness, more LED illuminants are often integrated on the same aluminum substrate to form a high-power LED light source module, which provides convenience for subsequent processing of various lamps, but integrating multiple LEDs on the aluminum substrate will inevitably cause heat accumulation , so it is necessary to add a radiator at the rear of the aluminum substrate, so that the post-manufacturer needs to design various radiators according to different lighting products, etc.
