The heat dissipation and protection of LED lamps is an industry-specific problem. From the analysis of thermal energy, heat (Q) a divergent power PD;UF;IF because when the I)ED efficiency reaches the standard value, the relative change of UF and IF is relatively small. Therefore, when a large number of LEDs are placed on a module, it will increase the difficulty of heat treatment.

The problem is that this heat will cause the temperature of the LED module to rise, and the increase in temperature will cause the T working voltage of the LED to decrease, and the intensity of light will decrease. The effect of heat dissipation design on LED life. With the increase in temperature, the LED light decays or even Damaged, the driver is also damaged due to over temperature, reducing the reliability and service life of the LED lamps. And affect the efficiency of the LED driver, damage the life of the magnetic components and output capacitors, reduce the reliability of the LED driver, and seriously reduce the life of the LED, and accelerate the light decay of the LED.

When designing LED lamps, good heat dissipation design is mainly due to The following considerations: Improve the luminous efficiency Waterproof Led Garden Light of the LED, increase the current (power), and reduce the junction temperature (Tj) of the LED chip. LEDs with high optical performance and high reliability depend on the junction temperature (Tj) of the LED chip. Among them, conduction and convection are more important for the heat dissipation of LED garden lights, and divergence is not important.

Therefore, a good thermal design is to manage the LED junction temperature Tj. Due to the low output beam of a single LED at this stage, for general lighting use, a large number of LED components are required to be placed in a module to achieve the required illuminance. In the case, the heat generated during the operation of the lamp cannot be dissipated into the air, which causes the LED module and drive circuit to work in an extremely harsh environment..The system should be optimized in the material selection structure design to solve the contradiction between the heat dissipation and product protection of LED lamps
