The Role Of LED Heat Sink

1. The LED lamp heat sink is a heat dissipation structure composed of the base of the LED heat sink and several fins. Unlike a single fin, the heat dissipation unit is a U-shaped or V-shaped channel formed by two adjacent fins and the base. Therefore, the influence of the pitch and the number of fins on the heat dissipation performance must be considered.

2. The continuous improvement of chip input power puts forward higher requirements for the packaging technology of these power LEDs.

3. Now the heat dissipation problem has become a key factor restricting the development of high-power LEDs. Especially for the application to car lights, because the structural design should conform to the aesthetic constraints of the vehicle model, the heat dissipation environment of the LED has been further deteriorated, so the heat dissipation problem of the LED lamp needs special consideration.
