Cover 8 is arranged in plastic heat radiation housing 5, is enclosed between the outer wall of insulating protective cover 8 and the upper inside wall of plastic heat radiation housing 5 and is set as
Lower chambers B, encloses between the inwall of insulating protective cover 8 and the lower inner wall of plastic heat radiation housing 5 and is set as an insulated cavity D, drives
Circuit board 2 is arranged in insulated cavity D, and lower ventilation slot 51 is arranged on the top of plastic heat radiation housing 5.In the upper cover of drive circuit board 2
If an insulating protective cover 8, the insulating protective cover 8 encloses with the bottom of plastic heat radiation housing 5 and is set as an insulated cavity D, by drive circuit
Plate 2 is arranged in insulated cavity D, can form effective electic protection, it is ensured that the safe handling of light fixture, it is to avoid leak electricity short-circuit
Risk, while the insulating protective cover 8 can intercept the hot-air come out from heat dissipation channel 61, it is to avoid drive circuit board 2
Toasted by hot-air for a long time, so as to effectively extend the service life of driving；Additionally by matching somebody with somebody for buckle 53 and draw-in groove 81
Close, insulating protective cover 8 can be made to be stabilized installation, simple structure is easy for installation；Lower ventilation slot 51 is arranged on plastic heat radiation shell
The top of body 5 so that whole radiating is not installed by insulating protective cover 8 and influenceed, it is ensured that proper heat reduction.
In this particular embodiment, the top of insulating protective cover 8 is provided with the cable-through hole 82 of insertion, cable-through hole 82 and cavity of resorption
Room B is connected with insulated cavity D, and the bottom of plastic heat radiation housing 5 is evenly distributed and is arranged at intervals with multigroup air vent 54, air vent
54 are connected with insulated cavity D.Driving operationally can also produce heat, the temperature in the insulated cavity D where driver circuit plate 2
When too high, air circulation can also be formed by air vent 54 and cable-through hole 82, so that the temperature in insulated cavity D is reduced, so as to have
The service life that effect extension drives；Other cable-through hole 82 can wear the electrical connection that wire is realized between lamp plate 2 and drive circuit.
In this particular embodiment, it is provided between the top of drive circuit board 2 and the top inner face of insulating protective cover 8
Gap, the presence in the gap can be prevented effectively from the risk that drive circuit board 2 skids off plastic heat radiation housing 5.
