Description

A kind of LED with radiator shines tool

Affiliated technology jaw city

The utility model relates to a kind of according to tool, is specifically related to a kind of LED with radiator and shines tool.

Background technology

Shine in the tool at existing LED, the heat radiation of LED luminous tube is by having heat radiating fins or relying on the pcb board of its connection to finish, this is concerning carrying small size fin, power near 1 watt or more the high-power LED, will cause that temperature is too high and reduces the life-span, also can influence the working stability of temperature control device.To this, many improvement projects are suggested, and in the disclosed a kind of lighting tool structural improvement of Chinese utility application prospectus CN2494918Y, its scheme can better not solve the heat dissipation problem that shines tool based on the LED of plastic components; At the disclosed a kind of LED traffic lights of Chinese utility application prospectus CN2636073Y, radiator structure still must improve, so shine tool for LED, the LED that contains more plastic components especially needs a kind of better radiator structure according to tool.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned LED provides the LED of a kind of good heat dissipation effect, long service life according to tool according to the shortcoming of tool.For achieving the above object, the utility model has adopted following technical scheme: this LED shines tool by the LED illuminator, control panel, the radiator that has heat conducting base that heat transfer efficiency is high, preceding lens, reflection shield, the lamp body that holds said modules, the protecgulum of lens is formed before fixing, described LED illuminator, heat generating components such as control panel link to each other with the heat conducting base of described radiator, lens before described, reflection shield both can directly link to each other with the heat conducting base of described radiator with non-heat generating components such as lamp bodies, also can high heat-conductive bridges link to each other by the heat transfer efficiency of setting up, the heat of heater members such as LED and high-power IC is shed fast, and pass to according to the space beyond the tool by non-heat generating components.For improving heat-conducting effect, described radiator has coupled being contacted by the closely connected curved surface of conducting-heat elements shape with described heat-conductive bridges, to increase contact area, can make better effects if as being coated with heat conductive silica gel again.Also the non-heat generating components according to tool can be able to be added heat-conducting layer, it can be made by heat-conducting metal or other Heat Conduction Materials such as heat-conducting plastic, the thermal conductivity of heat-conducting plastic can be selected to 100W/mK (approaching with cast aluminium) from 2W/mK (approaching with glass), for reducing the ratio that cost can reduce the heat-conducting plastic admixture, use repeatedly Shooting Technique can guarantee that heat-conducting layer has the hot conducting surface that exposes of contact space outerpace and connection heat-transfer device, also Heat Conduction Material can be coated on described preceding lens, the surface of non-heat generating components such as reflection shield and lamp body passes to radiator and space outerpace heat fast.Existing be unfavorable for heat radiation, can change it into Heat Conduction Material, heat is passed to according to beyond the tool by them according to using the conventional seals part between preceding lens, reflection shield and the lamp body of tool.For making described radiator with the curved surface that shines the tool assembly better the contact be arranged with heat-conductive bridges, heat-conductive bridges can be made of elasticity material, the direction of this elastic force makes its surface of contact connected components closely.

Outstanding effect of the present utility model is: owing to adopt said structure, heat-conductive assembly and heat-conducting area have been increased, the heat of heater members such as LED and high-power IC is transferred out fast, has reduced their temperature, also will improve the service life and the temperature control stability of device.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the cutaway view of the utility model embodiment.

Among Fig. 1, this LED is made up of radiator 114, contact surface 109, control panel radiator 110, supply line 111, seal 113, the heat-conducting layer 115 of the LED illuminator 101 of being with fin 112, control panel 102, preceding lens 103, lamp body 104, protecgulum 105, reflection shield 106, heat-conductive bridges 107, band heat conducting base 108 according to tool.
