LED bulbTechnical field
The present invention relates to LED application, specifically, relate to a kind of LED bulb.
Background technology
LED is widely used because of its significant energy-saving effect.Existing LEDbulb lamp is all the small light of below 15W, its profile is copy traditional incandescent lamp substantially, mainly be applicable to the place of the little illumination area requirements such as passageway, corridor, room and desk lamp, and for the place that the large lighting area such as factory floor, warehouse requires, then need high-power LED bulb lamp, because LED bulb heating is comparatively large, needs to rethink heat dissipation problem, and design new structure.
Summary of the invention
The object of the present invention is to provide a kind of LED bulb, to solve the energy-saving illumination problem in the place of the large lighting area requirement such as factory floor, warehouse.
For reaching this object, the present invention by the following technical solutions:
A kind of LED bulb, comprise screw socket, wiring board, power pack, radiator, heat conductive pad and lamp holder, described lamp holder comprises mount pad, metallic plate, LED light source and lens, described screw socket is arranged on outside one end of described radiator, described power pack is arranged in one end of described radiator, described wiring board is arranged in described power pack, described lamp holder is by the dismountable other end being connected to described radiator of mount pad, described metallic plate is arranged in the through hole at described mount pad center, and end face is contacted with radiator by heat conductive pad thereafter, described LED light source is arranged on the front end face of described metallic plate, the negative leads that described screw socket is drawn by wiring board is connected with described LED light source, described lens are arranged on the front end face of described metallic plate, and in described LED light source is enclosed in.
Preferably, described heat conductive pad is graphite heat conducting pad.
Preferably, described metallic plate is made up of copper or copper alloy.
Preferably, described radiator comprises heat radiation cage, upper mounting plate, lower installation board, described heat radiation cage is arranged between upper mounting plate and lower installation board, described screw socket is arranged on the upper surface of upper mounting plate, described power pack is arranged on the lower surface of upper mounting plate, and being positioned at heat radiation cage, described mount pad and lower installation board are threaded connection.
Preferably, described heat radiation cage is made up of thermal magnon heat sink material.
Preferably, the main body of described heat radiation cage is cuboid or cube.
Preferably, described heat radiation cage is turned down by one block of criss-cross wing plate and forms, and the corner of described heat radiation cage is also provided with the angle envelope of cylindricality.
Beneficial effect of the present invention is: structure is simple, is easy to manufacture, good heat dissipation effect, good energy-conserving effect, and lamp holder entirety is easy to change and safeguard.
