Summary of the invention
For the problems referred to above, the invention provides a kind of high-powered LED lamp.
To achieve these goals, the technical solution used in the present invention is: a kind of high-powered LED lamp, include great power LED, lamp holder, radiator, and great power LED is fixed on radiator, in the cavity that radiator forms between insulating part and reflection shield;
Described reflection shield is outside equipped with lampshade.
Described radiator and radiating fin are structure as a whole, and radiating fin has insulator outward, have some louvres on insulator.
Described lamp holder can be screw-type, bayonet type structure.
Described insulating part includes the hollow cylinder of upper end and the hollow round table of lower end, and there is a planar isolated centre.
Described insulating part arranged outside has external screw thread, coordinates the screw thread of lamp holder, makes both fastening.
Described radiating fin is distributed with radiating fin branch.
Described reflection shield is hollow similar cylinder or the structure of Rotary-table shape.
Described reflection shield surface is coated with aluminium, silver, and/or increases anti-film.
The inner surface of described lampshade is coated with anti-reflection film.
The present invention is provided with the cavity structure of reflection shield and insulating part composition in lampshade inside, expanded the receiving volume of lamp interior, can hold whole radiator, wherein radiator can adopt Extrusion Process of Aluminum Alloy Profile to be shaped, and area of dissipation is large, and quality is light, cost is low, and processing is simple.
High-power LED light source is fixed on the central authorities of radiator, and protrudes from reflection shield, on the surface of reflection shield, is coated with reflectorized material, as materials such as aluminium, silver, and on the surface of reflectorized material, is coated with the anti-layer of increasing, can effectively increase the reflecting effect of light, improves and reduces light loss.
The present invention has good internal structure, and radiating effect is outstanding, scientific optical treatment, and low processing cost, installs simply good looking appearance.
