Further, described heat radiation ridge is spacedly distributed perpendicular to described recess and rim of a cup.
Perhaps, described heat radiation ridge favours described recess and rim of a cup is spacedly distributed.
Further, described light cover is the optical lens of the intermediate projections formation of a circular panels.
Further, the one side that described optical lens is relative with described metal tub reflector bottom is the frosting distribution.
Compared with prior art, the utlity model has following beneficial effect:
(1) better heat radiating effect: led light source directly is embedded in metal tub reflector base recess, allows the heat of led light source pass to metal tub reflector bottom by thermal grease, is passed to the metal tub reflector again, thereby increases the area of dissipation of led light source.The metal tub reflector is a metal material, has good thermal conductivity.
(2) bright dipping is even: the utility model adopts the light cover of the optical lens that the intermediate projections of the circular panels be sprayed with one deck sand face forms, and makes the high-power LED chip luminous intensity of metallic reflection cup bottom even.
(3) volume is light and handy, and I﹠M is convenient, flexible and economical: because metal tub reflector of the present utility model and external driving power are separable, volume is little.As long as install metal tub reflector of the present utility model and external driving power during replacing.Therefore, it uses more convenient flexible.
(4) brightness height, energy-conserving and environment-protective: the utility model adopts the led light source of high-power LED chip, and enough strong brightness can be provided, and satisfies the social demand of energy-conserving and environment-protective.
(5) simple in structure, cost is low: the utility model only utilizes support, metal tub reflector, led light source and light cover just to form and forms.Therefore, simple in structure, save material, reduce the cost.
