Abstract
The invention discloses a high-power light-emitting diode (LED) lamp which comprises a lampshade (1) and an LED luminous body (2), wherein the LED luminous body (2) is arranged in the lampshade (1) which is in a paraboloid shape. The paraboloid-shaped lampshade (1) can be taken as not only a light distribution lamp but also a heat dissipation device, as well as a carrier of an LED light source, and under the condition of not increasing the cost of the lamp, the heat dissipation problem of the high-power LED lamp is solved.
Description
Technical field
The present invention relates to a kind of high-powered LED lamp, belong to the lamp lighting technical field.
Background technology
In general, whether the work of LED lamp is stable, and light decay and life-span, all directly related with the heat radiation of lamp body itself, the heat dissipation design of high-powered LED lamp mainly contains natural heat dissipation and two kinds of forms of auxiliary heat dissipation at present.
At present, the LED natural heat dissipation mainly adopts the aluminium radiating fin, and exactly aluminium radiator being made fin-like increases area of dissipation, improves radiating effect.But so not only increased the installation dimension of radiator, and directly improved the light fixture cost, be unfavorable for applying of LED lamp.In addition, also have to handle and improve radiating efficiency, but DeGrain can't replace radiator fully through the heat loss through radiation of lamp surface.
In recent years, the heat pipe heat radiation technology has begun to use, and has improved radiating effect, has reduced the weight of radiator, but has increased the radiator volume, also is unfavorable for the installation and the application of light fixture.
Through auxiliary heat dissipation is other a kind of radiating mode; Such as dispelling the heat through increasing the forced convertion cooling fan; Can increase cost too, and the reliability that reduced light fixture, the fault of radiator possibly directly reduce radiating effect; Even cause light fixture to damage, so this technology will progressively be eliminated.
Summary of the invention
The high-powered LED lamp that the purpose of this invention is to provide a kind of simple in structure, perfect heat-dissipating.
In order to reach above-mentioned technical purpose, technical scheme of the present invention is: a kind of high-powered LED lamp, comprise lampshade and LED illuminator, and said LED illuminator is arranged on the lampshade inboard, and said lampshade is a parabolic shape.
In order further to reach the purpose of heat radiation, said lampshade is the good material of heat conduction.
The present invention is at the lampshade inner surface LED illuminator that evenly distributes; And form tight the contact with lampshade inner surface; The good parabolic shape lampshade of heat conduction can both can be used as the carrier of led light source; Can be used as radiator again,, solved the heat dissipation problem of high-powered LED lamp not improving the light fixture cost and not increasing under the situation of light fixture volume.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Shown in accompanying drawing, high-powered LED lamp comprises lampshade 1 and LED illuminator 2, and lampshade 1 is through suspension ring 3 liftings, and said LED illuminator 2 is arranged in the lampshade 1.
Said lampshade 1 is the paraboloid shape.
Said lampshade 1 is heat conduction good metal material, both can be used as the carrier of LED illuminator, can be used as radiator again.
Said LED illuminator 2 is that the LED luminescence chip is installed on the FPC through paster technique, insulation between FPC and the lampshade 1.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
Claims (4)
1. a high-powered LED lamp comprises lampshade (1) and LED illuminator (2), and said LED illuminator (2) is arranged in the lampshade (1), it is characterized in that: said lampshade (1) is paraboloid shape or hyperbolic-parabolic shape.
2. high-powered LED lamp according to claim 1 is characterized in that: said lampshade (1) is the good material of a kind of heat conductivility.
3. high-powered LED lamp according to claim 1 is characterized in that: said LED illuminator (2) is attached to the inboard of lampshade (1), and closely contacts with lampshade (1) through highly heat-conductive material, thereby realizes heat radiation.
