Heat Dissipation ways of LED light

      LED lamps have the characteristics of energy saving, high efficiency, long service life and high reliability, so they are widely used in various industries. The LED lamp will continue to heat during use. If the heat cannot be taken away in time, it may reduce the service life and lighting brightness of the LED. Good heat dissipation design plays a very key role.

     We can use the head of the bulb to dissipate heat. In small lamps used at home, the space in the lamp often used to place part or all of the driving circuit that radiates heat, so that we can use the part of the head with a large metal surface to dissipate heat, because the head is closely connected with the metal electrode of the lamp holder and the power line, Therefore, part of the heat can be exported and dissipated through this part.

     The main purpose of using the lamp shell to dissipate heat is to reduce the temperature of the chip. Because the expansion value of the chip is very different from that of the metal heat conduction and heat dissipation articles we often use, the chip cannot be directly welded to avoid direct damage to the chip by high and low temperature thermal stress values; The lamp shell is designed into the shape of heat sink to increase the heat dissipation area of the shell and speed up the heat dissipation process. This scheme is commonly used in outdoor large LED equipment.

    Heatsink with high density fin design is the most common way to dissipate heat. Increase the area of heat dissipation. Combined with the application of heat conducting materials, connect the radiator with LED heating chip to dissipate heat quickly and efficiently. This heat dissipation method has the best effect, higher cost, but better stability. It is suitable for long-term use or high-power LED equipment.
