Description
[technical field]
The utility model relates to a kind of light fixture, is specifically related to a kind of great power LED shot-light.
[background technology]
LED is owing to possess multinomial ripe advantage, for example, power saving, high efficiency, high reaction speed, life-span be long, with not mercurous multinomial environmental protection advantage, add characteristics such as upper volume is little, in light weight, obtained application more and more widely.In many advantages of LED, it should be its advantage in shape-designing, also is what traditional gas-discharge lamp lighting can't be than U.S..
How to dispel the heat is one of key issue of LED product needed solution, and the rising of temperature can cause the reduction of properties of product, and efficient reduces, and red shift of wavelength reduces problems such as service life.
Existing LED shot-light mainly is made up of led chip, aluminium base, aluminum alloy casing.Aluminium base is fixedlyed connected with metal shell.It mainly is the heat conductivility that utilizes aluminium base and metal shell self, and the heat that led chip is produced distributes.Yet this type of design must guarantee that aluminium base is connected with the plane of metal shell and could guarantee radiating effect, has so just seriously limited the shape-designing of LED light fixture, is unfavorable for bringing into play light, little, the thin characteristics of LED light fixture.
[utility model content]
The purpose of this utility model provides a kind of LED shot-light at the deficiencies in the prior art exactly, can realize the heat conduction in the small space, when guaranteeing radiating effect, promotes the free degree of light fitting shape design.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of novel large-power LED shot-light, comprise the metal shell of forming by metal top cover 2 and metal lower cover 10, in metal shell, be fixed with aluminium base 700, on aluminium base 700, be equipped with a plurality of to the LED of metal shell external irradiation module 7, the height that it is characterized in that also being sticked on the metal shell inwall is led graphite flake 6, and this height is led graphite flake 6 other ends and closely contacted with aluminium base 700 bottom surfaces.
The thermal conductivity factor that described height is led graphite flake 6 in-planes is not less than 300W/m.K, and the thermal conductivity factor of vertical direction is not less than 10W/m.K.
The thickness that described height is led graphite flake 6 is 0.1mm to 0.5mm.
Described height leads graphite flake 6 and aluminium base 700 all is fixed on the metal top cover 2.
Described height is led graphite flake 6 and is fixed on the metal top cover 2 by geometrical clamp 3.
Be provided with a plurality of lens openings on described metal lower cover 10, lens module 9 is housed in lens opening, described LED module 7 extend in the lens module 9.
Connect by button bit between described metal top cover 2 and the metal lower cover 10.
Described metal shell is an aluminum shell.
The beneficial effects of the utility model are: adopt rational radiator structure, realized the heat conduction in the small space, the heat that LED is produced can pass to external heat sink rapidly, is dispersed in the air at last.Guarantee the life-span of LED product, improved the free degree of LED PRODUCT FORM DESIGN simultaneously.
