How to do a good job of cooling the solar street light source?

Solar street lights have a long life and can work by reducing the power at night, so they will be used for solar street lights or general projects. However, the quality of solar street lights is uneven, and LEDs with serious light decay may attenuate 50% of the illuminance in half a year, so be sure to choose solar street lights with slower light decay. The most important thing for solar street lights is to do a good job of heat dissipation and constant current. Constant current can be driven by an additional constant current or use a controller for constant current. Heat dissipation must rely on aluminum plates to dissipate heat. It is best to add copper sheets or copper tubes under the aluminum plate. To more effectively dissipate heat and control the temperature, the life of the solar street light will be longer. Whether the heat dissipation of the solar street light source is good or not has a great impact on the light efficiency and life of the LED light source. If the heat emitted by the LED cannot be dissipated in time, it will cause uneven distribution of thermal stress, which will lead to a decrease in the luminous efficiency of the chip and the excitation efficiency of the phosphor. When the temperature changes, the performance and packaging structure of the LED light source will be affected, thereby affecting the reliability of the LED. Therefore, try to choose a lamp head with better heat dissipation effect, and don't try to use a lamp head with a heat dissipation and cutting corners. For details, visit: www.chz-lighting.com.
