Abstract
The utility model is suitable for the lighting field, and provides an LED lighting device. The high heat conductivity LED lighting device comprises an LED packaging body and a heat radiating piece, wherein the chassis of the LED packaging body is connected with the heat radiating piece through a metal connecting body. Since metal with better heat conductivity is used for replacing original insulators or insulation paste with bad heat conductivity, heat of LED can be transmitted outside better, and the heat radiation effect of systems is improved.
Description
Technical field
The utility model belongs to lighting field, relates in particular to a kind of high-termal conductivity LED lighting device.
Background technology
The brightness of LED, power all get a promotion in recent years, begin to be used for application such as backlight and electrical lighting, and the package cooling problem of LED is also quietly appeared in one's mind.When traditional LED is fixed on the pcb board, be provided with an insulating barrier between its base and the radiating piece, be subject to the relatively poor heat conductivility of insulating barrier, the heat of LED can't be conducted well, cause the integral heat sink weak effect.

The utility model is achieved in that a kind of LED lighting device, comprises LED packaging body and radiating piece, and the base of described LED packaging body is connected with described radiating piece by metal connector.
Further, described LED packaging body comprises:
Substrate;
Be fixed on the LED luminescence chip on the described substrate;
The positive and negative electrode that is connected with described LED luminescence chip;
Cover on the heat conductive silica gel package on the described LED luminescence chip;
Be positioned at the plastic stent of described substrate below;
The LED metal heat-conducting electrode that be positioned at described plastic stent below, contacts with described metal connector.
Further, described LED luminescence chip is fixed on the described substrate by silver slurry glue.
Further, described metal connector is a tin.
Further, described radiating piece is connected by pin with described metal connector.
Further, described radiating piece is connected by screw with described metal connector.
Further, described radiating piece is a metal material.
In the utility model,, make the heat of LED can better conduct to radiating piece, improved the radiating effect of system owing to use the better metal connector of heat conductivility to replace the insulator or the insulating cement of original heat conductivility difference.
Description of drawings
Fig. 1 is the structure principle chart of the LED lighting device that provides of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Among the utility model embodiment, a metal level is set between LED packaging body base and radiating piece, LED conducts heat by this heat conductivility preferred metal.
Fig. 1 shows the structural principle of the LED lighting device that the utility model embodiment provides, and for convenience of description, only shows the part relevant with the utility model.
With reference to Fig. 1, this LED lighting device comprises LED packaging body and the radiating piece 1 that is connected with the LED packaging body, and wherein the LED packaging body is connected with radiating piece 1 by metal connector 2.
This LED packaging body comprises LED metal heat-conducting electrode 3, silver slurry glue 4, plastic stent 5, LED luminescence chip 6, the positive electrode 7 that is connected with the LED luminescence chip, negative electrode 8, copper-foil conducting electricity 9, insulating barrier 10, heat conductive silica gel package 11 and substrate 12.Wherein LED luminescence chip 6 is fixed on the substrate 12 by silver slurry glue 4, heat conductive silica gel package 11 covers on the LED luminescence chip 6, it is indoor to make the LED luminescence chip be in an enclosed cavity, and plastic stent 5 is positioned at the below of substrate 12, and contacts with metal connector 2 by LED metal heat-conducting electrode 3.
Structure shown in Figure 1 is with respect to traditional structure, the part that insulating barrier 9 is positioned at metal heat-conducting electrode 3 belows hollows out, and adopt heat conductivility good metal connector 2 to replace, when above-mentioned LED luminescence chip 6 owing to work long hours and adstante febre, its heat can conduct to radiating piece 1 by plastic stent 5, LED metal heat-conducting electrode 3, metal connector 2 successively, and the use of metal connector 2 has promoted the radiating effect of system greatly.
Further, this metal connector 2 is the tin layer.
Further, radiating piece 1 is also selected metal material for use.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
