Problems solved by technology

[0003] 1. Use fans for heat dissipation to meet the heat dissipation requirements of high-power LED light sources. This method has obvious technical defects, because the basic life of LED light sources is 50,000 hours, and the life of fans is difficult to meet such long-term needs. If the fan cannot work normally, the high-power LED light source will be damaged, and the installation of the fan device will increase energy consumption, resulting in waste of energy, and is not conducive to the miniaturization of the LED light source;
[0004] 2. At present, the interior of the lamp uses aluminum plate heat dissipation structure, die-casting parts and other heat dissipation parts to help the LED light source module dissipate heat. This makes the lamp head too heavy and not suitable for hanging on the existing lamp post, and the installation is not convenient; at the same time, the existing The advanced LED light source module is provided with an insulating layer between the aluminum plate and the circuit board, while the LED light source is packaged on the circuit board. The heat generated by the LED light source must pass through the circuit board and the insulating layer before being transmitted to the aluminum plate, and the heat transfer efficiency is low;
[0005] 3. The use of heat dissipation paste for heat dissipation will cause greater light attenuation of the LED light source, which cannot be widely used in large-area lighting

Abstract

The invention discloses an LED light source module with an efficient heat dissipation function. According to the LED light source module, through holes are formed in a circuit board, LED light sources are directly fixed onto a heat dissipation substrate after penetrating through the through holes, heat generated during working of the LED light sources is directly transmitted onto the heat dissipation substrate, therefore, the temperature of the LED light source module during work can be effectively controlled, and finally the purposes of prolonging the service life of the LED light source module and enhancing the lighting effect are realized. The heat dissipation efficiency of the LED light source module is enhanced; meanwhile, other complex heat dissipation structures are not added, therefore, on one hand, the size of the LED light source module can be controlled easily so as to widen the application range of the LED light source module, and on the other hand, the production technology of the LED light source module can be simplified and the production cost can be lowered.

Description

technical field [0001] The invention relates to an LED light source module, in particular to an LED light source module with high heat dissipation. Background technique [0002] With the development of science and technology, LED light sources are considered as the fourth generation of lighting sources. LED light sources have been widely used in various lighting fields due to their advantages such as high luminous efficiency, low power consumption, no need for high voltage, and high safety. Street lights have become An indispensable lighting tool for urban nightlife. Generally, street lamps need to work for a long time, even in severe weather such as storms, rain, and snow. At the same time, the brightness of street lamps shining on the ground is constantly emphasized. However, the higher the power of the LED light source, the greater the heat generated. If the heat dissipation capacity is insufficient, the temperature in the LED light source will be too high, which will cau...
