As being further improved for said program, the thermal window is shutter.
As being further improved for said program, the nose threads of the fixed face ring are connected with local optically focused ring, described The side of local optically focused ring is provided with solar panel.
As being further improved for said program, the circumferential surface of the reflector is provided with several evenly arranged heat emission holes.
As being further improved for said program, the lampshade is back radiating fin high density centralized configuration.
As being further improved for said program, the reflector is aluminium cup, and the reflector inner surface is provided with plating Layer.
As being further improved for said program, the reflector inner surface is provided with the curved surface of control light-emitting angle.
As being further improved for said program, light source bracket is provided in the lampshade, the concentration area source passes through Light source bracket is fixed in lampshade.
As being further improved for said program, the lamp body connect use with power supply conversion driver.
The beneficial effects of the utility model:
A kind of high-power LED downlight of high intensity of the utility model is equipped with using lampshade and area source is concentrated to be illuminated, By the radiating fin and thermal window being provided on lampshade, the heat generated when area source work will be concentrated to discharge, energy Lamp body is cooled down in time so that low resistance is maintained when lamps and lanterns use, luminous power higher, the service life is longer.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings Other design schemes and attached drawing:
