Abstract
The utility model discloses an LED (Light Emitting Diode) radiating base plate which is an aluminum base plate. The aluminum base plate comprises an aluminum base plate body which comprises a weld preventing white oil layer, a copper foil layer, an insulating heat conductive layer and a heat conductive aluminum product layer which are sequentially arranged, wherein an oxidation preventing layer which is a nickel plating layer is arranged inside the aluminum base plate body. With the adoption of the technical scheme, based on original good heat conductivity of the LED radiating base plate, the corrosion resisting and oxidation resisting performances are enhanced, so that the service life of the LED lamp in special environments such as high moisture, high slat content and large temperature difference between day and night.
Description
Technical field
The utility model relates to a kind of LED heat abstractor, especially a kind of LED heat-radiating substrate that can be used under particular surroundings.
Background technology
The advantages such as the durability of LED lamp and intensity of illumination are enough, and be applied to generally that in the LED lamp, heat-radiating substrate is aluminium base.And the LED aluminium base of present stage is mainly used in building lighting, and tunnel illumination in the engineerings such as night scene, is applied in the aluminium base of this type of lighting installation, and owing to being in conventional environment, therefore the adaptive capacity for the material of aluminium base own requires lower.And the beacon that is applied to some island of part LED lamp, the illumination of seashore harbour, the residing environment of the residing environment in this type of region and previous all products, fully not identical, high moist, high salinity, day and night temperature is large, the product that uses under this environment is for having relatively high expectations of product itself.
As shown in Figure 1, aluminium base 1
,Comprise the anti-welding white oil coating 2 that sets gradually
,, copper foil layer 3
,, thermal insulation layer 4
,And heat conduction aluminium coating 5
,, heat conduction aluminium coating 5 wherein
,Be positioned at the aluminium base back side, and because the molecule of aluminium is comparatively active, high moist, under highly-saline environment, easily oxidation is corroded, and after aluminium base is subject to oxide etch, for the performance of integral LED lamp, as light fixture service life, aluminium base thermal diffusivity etc. will directly impact.
Thus, the inventor considers existing LED heat-radiating substrate is improved, and this case produces thus.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of simple and reasonable, convenient to use, the LED heat-radiating substrate of antioxidant effect preferably arranged.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of LED heat-radiating substrate, described aluminium base comprises the aluminium base body, this aluminium base body comprises anti-welding white oil layer, copper foil layer, thermal insulation layer and the heat conduction aluminium layer that sets gradually, described aluminium base body inboard is provided with anti-oxidation processing layer, and described aluminium base body inboard is provided with anti-oxidation processing layer.
Further, described anti-oxidation processing layer is led and is arranged on hot aluminium coating.
Further, described inoxidzable coating is nickel coating.
The inventor has increased inoxidzable coating on the aluminium base original structure, and this inoxidzable coating is nickel coating.Make the utility model on original thermal conductivity good basis, strengthened corrosion-resistant and oxidation resistant performance, and then extended the LED lamp high moist, high salinity, the service life under the particular surroundings such as day and night temperature is large.
Description of drawings
Fig. 1 is existing LED aluminum substrate structure profile.
Fig. 2 is the utility model section of structure.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: see also shown in Figure 2, a kind of LED heat-radiating substrate, this LED heat-radiating substrate is aluminium base, described aluminium base comprises aluminium base body 1, described aluminium base body 1 comprises anti-welding white oil coating 2, copper foil layer 3, thermal insulation layer 4 and the heat conduction aluminium coating 5 that sets gradually, described aluminium base body 1 inboard is provided with anti-oxidation processing layer 6, and described inoxidzable coating 6 is arranged on heat conduction aluminium coating 5, and described inoxidzable coating 6 is nickel coating.
After increasing this layer surface treatment, the high heat conduction aluminium at the back side will be subject to the protection of this nickel coating, and then make and the utlity model has following advantage:
1, thermal conductivity is unaffected;
2, decay resistance increases;
3, increase the service life of product;
4, be conducive to client's backside coating heat-conducting glue and welding use.
The above record, only for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do all belong to the scope of the claims that this creation is advocated, and are not limited to those disclosed embodiments.
