A radiator that can contact the heat dissipation unit is detachably installed on the lamp board, and the radiator is also covered in the lampshade. The radiator includes a heat dissipation plate and heat dissipation fins. The heat dissipation plate is fixedly connected to the lamp board by fixing bolts. Ventilation holes are provided on both sides of the lampshade, and dust screens are installed in the vents. Silicone grease is filled between the heat dissipation plate and the heat dissipation unit.

[0005] As a preferred solution of the present invention, the lampshade and the mounting plate are fixedly connected by bolts.
