Said power pack connects and fixes with the head of said thermal column mutually.

Said lamp base and said insulation holder are fixedly connected through rivet.

Said lamp base is the lamp base of ALR111 light fixture, and the nominal size of said reflector is

111mm.

Said reflector and said thermal column adopt aluminium to process, and said insulation holder and said power pack adopt plastic cement to process.

The beneficial effect of the utility model is: because the utility model comprises reflector, lamp base, insulation holder, thermal column, drive circuit board, FPC, power pack; Said FPC is provided with several adopting surface mounted LEDs; Said insulation fixed seating is in the afterbody outside of said reflector, and said thermal column is positioned at said reflector, and hole and said insulation holder that the afterbody of said thermal column passes said reflector afterbody are fixedly connected; Said reflector is gripped; Said lamp base and said insulation holder are fixedly connected, and said drive circuit board is positioned at said power pack, and the head of said power pack and said thermal column is fixedly connected; Said FPC is coated on the periphery of said thermal column, and several said adopting surface mounted LEDs are around the periphery that is distributed in said thermal column; The utility model adopts adopting surface mounted LED and FPC, around the periphery that is distributed in said thermal column, makes LED along circumferential being evenly distributed LED; The edge is the light projector good uniformity circumferentially, and through said thermal column and said reflector the heat that LED produces is in time distributed rapidly, has avoided LED overheated; Increase the service life; Simple in structure, light efficiency is high, so the utility model is simple in structure, light projector even, efficient energy-saving;

Because the said adopting surface mounted LED of the utility model axially is provided with plurality of rows along said thermal column, so the distribution density of LED is higher, the optical density after the reflection is higher, can reach the effect of existing Halogen lamp LED after the reflection, so the utility model goes out the optical density height;

Because the said lamp base of the utility model is the lamp base of ALR111 light fixture; The nominal size of said reflector is

111mm; Therefore profile and the reflective Halogen lamp LED of existing ALR111 are consistent; Can substitute

reflective Halogen lamp LED of 111mm, electricity-saving lamp and cold cathode luminous source fully; So the utility model can directly substitute the halogen reflectoscope in the existing floodlight and needn't change light fixture, reaches energy-conservation and cost-effective purpose.
