Methods to Optimize the Heat Dissipation Performance of LED High Power Beacons

Ⅰ. The result of poor heat dissipation of LED high-power beacons

The poor heat dissipation of the LED high-power beacon will directly cause the service life to be reduced, and the luminous flux will be reduced, which will cause the degradation of the material quality. So we need to optimize the heat dissipation performance of the LED high-power beacon.


Ⅱ. Method for optimizing heat dissipation performance of LED high-power beacon

1. Optimization of heat dissipation structure  

The optimization of the heat dissipation structure of the LED high-power beacon must first optimize the fin structure. According to the data and results of the simulation model, the fin height and length are analyzed. Generally speaking, the chip height of the led high-power beacon is usually 0.05- Within 0.11m, the heat dissipation performance in this range is the best

The heat transmission channel of the LED lamp starts from the chip, goes to the notch, through hole and then to the substrate. For other excess heat, it is mainly removed through the heat sink channel. In this way, it can be based on the specific conditions of the LED high power beacon. By transforming the internal structure and module of the LED lamp, finding and measuring the optimal solution, realizing the data statistics of the heat distribution, so as to formulate the parameters of the gap and the through hole according to the actual situation, and increase the maximum heat dissipation value through the fin combination and spacing setting. To achieve high performance of fin heat dissipation.

  

2. Material selection

The selection of LED lamp materials is very important. It is necessary to analyze the working environment and heat dissipation requirements of the LED high-power beacon, and continuously expand the new high-performance heat dissipation materials. At present, the heat dissipation materials of LED high-power beacons are mainly copper, aluminum, and aluminum alloys, supplemented by other new materials.

In recent years, the development of new LED heat dissipation materials has also been continuously improved, and new heat dissipation materials have also made great progress, further expanding the application of LED lights in different working environments. In addition, with the development of electronic equipment and changes in the working environment of LED high-power beacons, the performance and shape of heat-dissipating materials are constantly being introduced, and great progress has been made.

  

3. Performance optimization  

The performance of LED high-power beacons must be optimized before design and production. Temperature experiments and data statistics must be done to design products with the most optimized performance in different work scenarios. In the test process, the performance optimization of the LED high-power beacon must be set according to the working performance of the test environment, equipment, etc., and the optimal solution must be found through the simulation test. During the test, the temperature must be kept constant and the simulation must be the best. The optimization result of the LED lamp in the best condition can adjust the performance, and achieve the optimization of performance through the adjustment of materials and structure.
