An embodiment of the present utility model is as follows: a first air outlet hole is provided on the top cover, a number of evenly distributed diversion grooves are provided on the outer wall of the light source base, and The second air outlet through hole, the first air outlet through hole, the diversion groove, and the second air outlet through hole communicate with each other to form an air outlet channel.

An implementation manner of realizing the present utility model is: the fan is fixedly installed at the top position in the second ventilation hole of the light source base.

The beneficial effects of the utility model are:

The utility model participates in the heat dissipation of the whole light source by designing a sunflower-shaped radiator at the bottom of the lamp. In addition, a fan is installed in the light source assembly, and the heat of the LED light source part is exported to the lampshade through the principle of air circulation through external force, so as to achieve The purpose of heat dissipation. The LED drive power supply is installed inside the cavity, so that the heat generated by the drive power supply can also be fully exported, thereby prolonging the service life of the lamp and reducing the LED light decay. This design method also enables users to replace the original light source components more conveniently. Therefore, the utility model has simple structure, good heat dissipation effect and long service life, and realizes high power to meet the performance requirements of replacing 150W products.
