Problems solved by technology

The higher the power of the LED, the greater the heat generation, and the heat generated by a single high-power LED and an integrated high-power LED is very concentrated. At present, the heat sink made of metal materials with good heat dissipation performance such as aluminum and copper is generally used. Its heat dissipation capacity is obviously insufficient, and increasing the volume and area can no longer significantly reduce the thermal resistance, which makes the heat energy emitted by the LED unable to be conducted and released in time, which seriously affects the work of the LED.

The end portion of a heat dissipation piece body of the heat dissipation piece is provided with an air inlet, the end portion of a heat dissipation piece body of the heat dissipation piece is provided with an air outlet, and a fan is arranged at an air inlet of an air inlet pipe.

Description

technical field [0001] The invention relates to a heat dissipation structure, in particular to a heat dissipation structure of an LED lamp. Background technique [0002] With the development of semiconductor lighting technology, LED has gradually developed from traditional low power to single high power and integrated high power. However, LED can only work normally under a certain temperature. The higher the power of the LED, the greater the heat generation, and the heat generated by a single high-power LED and an integrated high-power LED is very concentrated. At present, the heat sink made of metal materials with good heat dissipation performance such as aluminum and copper is generally used. Its heat dissipation capacity is obviously insufficient, and increasing the volume and area can no longer significantly reduce the thermal resistance, which makes the heat energy emitted by the LED unable to be conducted and released in time, which seriously affects the work of the LE...
