Technical field
The utility model relates to a kind of improvement of LED lamp structure, is a kind of improvement that has the great power LED lamp structure of heat abstractor specifically.
Background technology
Light emitting diode is as a kind of illuminating source since its have the luminosity height, produce when energy consumption is low, luminous that heat is low, advantage such as long service life, rich color and volume are little, by being applied in illumination and the decorative lamp more and more widely.Because single light emitting diode illumination is lower, people adopt with light emitting diode in parallel and or be together in series, the form that forms array provides to be enough to for people's illumination and environmental decoration light fixture.People are called great power LED lamp with the led lamp more than the 1W.For powerful led lamp, owing in array, used the great light emitting diode of quantity, even the heat that produces during each lumination of light emitting diode is low, a large amount of use light emitting diodes, the middle heat that produces also is appreciable in the light fixture cavity of sealing relatively.According to surveying and determination, powerful led lamp, the energy major part that is consumed has changed into heat energy, and the increase of heat has reduced luminous flux, has reduced the high advantage of light-emitting diode luminance, and influenced the service life of lumination of light emitting diode body.If the possibility that the operating temperature of light emitting diode above 80 ℃, then can cause the illuminator of light emitting diode to burn.This shows that can the heat dissipation problem of high-power and high-luminance led lamp be to be related to light emitting diode become the big problem of capturing illumination and/or ornamental lamp light source as main stream light sources.At present, a kind of device that is applicable to the great power LED lamp heat radiation is arranged, be referred to as solid heat radiation cup, said solid heat radiation cup is by heat radiation cup cup, cup base, bowl cover and lens are formed, on the cup, following two ends all are threaded, cup base all is connected with cup by screw thread with bowl cover, and the aluminium base of light emitting diode is fixed in cup base by heat conductive silica gel, and lens are fixed on the light emitting diode, again with at the bottom of the cup, cup, bowl cover is connected with cup by screw thread, said heat radiation cup is fixed in screw socket by insulator, and screw socket is twisted in the screw socket seat, and two utmost points of light emitting diode link with two wiring end points of screw socket respectively.After great power LED lamp was connected power supply, the heat that produces during light emitting diode work will be passed to the heat radiation cup by heat conductive silica gel more earlier by the aluminium base of light emitting diode, and heat is disseminated away.But, this heat radiation with great power LED lamp of solid heat radiation cup, its efficient is still not high enough, has influenced the efficient and the use of light fixture.
Summary of the invention
The purpose of this utility model is to provide a kind of great power LED lamp that has heat abstractor, it can realize the heat that more effective bulk storage high-power and high-luminance led lamp produces when work, improve the illumination of led lamp when work, prolong the service life of led lamp, reduce the cost of illumination or light decoration.
For achieving the above object, the utility model adopts following technical proposals:
A kind of great power LED lamp that has heat abstractor, comprise by heat radiation cup cup, cup base, the solid heat radiation cup that bowl cover and lens are formed, the two ends up and down of cup all are threaded, cup base links to each other with cup by screw thread with bowl cover, two utmost points of light emitting diode respectively with aluminium base on two wiring points link, two contacts on the aluminium base link by lead and power supply source, heat radiation cup fixing hole is set on the aluminium sheet of light fixture, said heat radiation cup bowl cover screw thread passes said fixing hole, by the screw thread on the said bowl cover, lens and cup are fixed on the aluminium sheet of light fixture, and the edge of aluminium sheet links to each other with the lamp housing of light fixture by heat conductive silica gel.
In technique scheme, the thickness of said aluminium sheet is 0.5-3mm.
In technique scheme, said aluminium sheet can be a surface plate, also can be spherical plate.
In technique scheme, the spherical radius of said spherical plate is 550-600mm.
In technique scheme, said aluminium sheet can be a planar rectangular, plane square, and planar rondure, oval in plan can be the sphere rectangle also, sphere is square, sphere circle, sphere ellipse.
In technique scheme, on said aluminium sheet, be provided with pod apertures.
The utility model has more following effects and good effect:
Because heat radiation cup fixing hole is set on aluminium sheet, said bowl cover passes said fixing hole, by screw thread cup is fixed in said aluminium sheet, like this, when light emitting diode is switched on power supply, begin when luminous, the heat that light emitting diode produced, to diffuse to space around the heat radiation cup by heat radiation cup close-connected with it, also the light fixture aluminium sheet by being connected with bowl cover with cup is with the heat transmission on the said aluminium sheet, the edge of aluminium sheet links to each other with the lamp housing of light fixture by heat conductive silica gel again, and then make and reach lamp shell by heat conductive silica gel again by the heat that on aluminium sheet, accumulates, increased the diffusion of heat.
Owing on said aluminium sheet, increase the pod apertures that perforation is set again, make that the diffusion of the heat that light emitting diode produced is further strengthened again.
After tested, after the same time of energising, adopt structure of the present utility model, heat radiation cup fixing hole is set, cup passes said fixing hole and is fixed in said aluminium sheet, with after the lamp housing of light fixture links to each other, the temperature of lamp interior is than the light fixture that structure of the present utility model is not set by heat conductive silica gel at the edge of aluminium sheet, and temperature has reduced 8-10 ℃.
The utility model provides a kind of great power LED lamp that has heat abstractor, it can realize the heat that more effective bulk storage high-power and high-luminance led lamp produces when work, improve the illumination of led lamp when work, prolong the service life of led lamp, reduce the cost of illumination or light decoration.
