HIGH-POWER LED LIGHTING DEVICE

摘要

A high-power LED lighting device comprises a casing (11), an LED lamp set (14), a radiator (12), and a fan (13) for increasing the heat dissipation speed of the radiator (12). The LED lamp set (14) and the radiator (12) are fixed in the casing (11). The LED lamp set (14) is adhered to the radiator (12). The fan (13) is fixed inside the casing (11). The direction in which the fan (13) blows is directed to the radiator (12). The fan (13) can increase the heat dissipation speed of the radiator (12), so as to improve the heat dissipation efficiency of the LED lighting device and extend the service life of the LED lamp set (14).
