The utility model provides an efficient heat-conducting high-power aluminum substrate with low cost and good heat-conducting performance. The aluminum substrate comprises an aluminum plate, an insulating layer, a conducting layer and a protective layer, which are compounded together in sequence, wherein the insulating layer, the conducting layer and the protective layer are provided with seat holes for installing LED (light emitting diode) chips; electrode holes for installing electrodes are arranged at two sides of the seat hole on the protective layer; and the lower surface of the aluminum plate is coated with a heat-conducting insulating layer. The efficient heat-conducting high-power aluminum substrate provided by the utility model has the advantages of low cost, good heat-conducting performance and the like, and can meet the requirements of high-power LED lighting.
Description
Technical field
The utility model relates to a kind of aluminium base, especially a kind of high-power aluminium base of high-efficiency heat conduction.
Background technology
Because it is at present increasing to the power requirement of LED lamp; And the volume size of LED lamp is more and more littler; The heat conductivility of the base plate for packaging of the existing LED of being used for lamp can not satisfy the needs of high-powered LED lamp; The inferior quality that causes high-powered LED lamp greatly reduces the useful life of high-powered LED lamp, thereby has hindered the development of high-power LED lamp.
The utility model content
The utility model provides that a kind of cost is low, the high-power aluminium base of the high-efficiency heat conduction of good heat conductivity.
Realize the high-power aluminium base of the high-efficiency heat conduction of the utility model purpose, comprise the aluminium sheet, insulating barrier, conductive layer and the protective layer that are combined with each other successively, said insulating barrier, conductive layer and protective layer are provided with the seat hole that is used to install led chip; On the said protective layer, the both sides that is positioned at said seat hole is provided with the electrode hole that installing electrodes is used; The lower surface of said aluminium sheet is covered with the heat conductive insulating layer.
Said heat conductive insulating layer is an alumina insulating layer.
The beneficial effect of the utility model is following:
The high-power aluminium base of the high-efficiency heat conduction of the utility model; Be located on the aluminium sheet because the seat hole of led chip will be installed, the heat that makes led chip produce directly dispels the heat through aluminium sheet, has improved radiating effect greatly; And the lower surface at aluminium sheet is covered with the heat conductive insulating layer; Not only better heat conduction can also be played the purpose of insulation, so low, the good heat conductivity of high-power aluminium base cost of the high-efficiency heat conduction of the utility model, can satisfy the demand of high-power LED illumination.
Description of drawings
Fig. 1 is the structural representation of the high-power aluminium base of the utility model high-efficiency heat conduction.
Embodiment
The embodiment of the utility model is following:
As shown in Figure 1, the high-power aluminium base of the high-efficiency heat conduction of the utility model comprises the aluminium sheet 2, insulating barrier 3, conductive layer 4 and the protective layer 5 that are combined with each other successively, and said insulating barrier 3, conductive layer 4 and protective layer 5 are provided with the seat hole 8 that is used to install led chip 1; On the said protective layer 5, the both sides that is positioned at said seat hole 8 is provided with the electrode hole 9 of installing electrodes 6 usefulness; The lower surface of said aluminium sheet 2 is covered with heat conductive insulating layer 7.
Heat conductive insulating layer 7 is an alumina insulating layer.
The high-power aluminium base of the high-efficiency heat conduction of the utility model; Be located on the aluminium sheet 2 because the seat hole 8 of led chip 1 will be installed, the heat that makes led chip produce directly dispels the heat through aluminium sheet, has improved radiating effect greatly; And the lower surface at aluminium sheet 2 is covered with heat conductive insulating layer 7; Not only better heat conduction can also be played the purpose of insulation, so low, the good heat conductivity of high-power aluminium base cost of the high-efficiency heat conduction of the utility model, can satisfy the demand of high-power LED illumination.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection range that claims of the utility model confirm.
