1. An LED light dedusting/cooling system comprising:
- a housing receiving therein a control member, a fan, a heat sink and an LED module, the fan and the LED module being respectively disposed on two opposite sides of the heat sink; and
a vibrator received in the housing and disposed on one side of the heat sink proximal to the fan and positioned between the heat sink and the fan;
wherein the housing includes a light seat and a light shade mated with the light seat, a winding passage being annularly defined between a circumference of the light seat and a circumference of the light shade;
wherein the winding passage includes a first passage positioned between a free end of a radial flange of a nonlinear rim and an axial skirt section of the nonlinear rim, the first passage vertically extending from a first end of the winding passage to communicate with a second passage, the second passage horizontally extending to communicate with a third passage, the third passage vertically extending to a second end of the winding passage to communicate with a receiving space of the light seat.

Abstract
An LED light dedusting/cooling system includes a housing receiving therein a control member, a fan, a heat sink and an LED module. The fan and the LED module are respectively disposed on two opposite sides of the heat sink. The LED light dedusting/cooling system further includes a vibrator received in the housing and disposed on one side of the heat sink proximal to the fan and positioned between the heat sink and the fan. In operation, the vibrator can vibrate between the heat sink and the fan to shake (or shock) off the dust or alien articles attaching to the fan and the heat sink. Then, the fan operates to blow out the dust from the housing.
