Background technology
Compare with conventional lamp, the LED light fixture has nonhazardous, and is pollution-free, without stroboscopic, energy consumption is low, and light efficiency is high, life-span length etc. advantage, it more and more is subject to everybody favor, and LED has heat generation, does not go out as heat is loose, local temperature is just too high, the light decay aggravation causes shorten the service life of LED, so LED lamp heat dissipation problem is exactly the topic that the art personnel need to capture always.
A kind of radiator structure is arranged, and is with common heat conduction plastic rubber shaping, but common heat conduction plastic cement thermal conductivity factor is lower, and it is relatively poor to dispel the heat; Be exactly to use the high heat-conductivity conducting plastic rubber shaping in addition, high heat-conductivity conducting plastic cement thermal conductivity factor is higher, and heat radiation is better, but on-insulated; Be exactly that the interior chimeric aluminium alloy of common heat conduction plastic cement is one-body molded in addition, its heat radiation is better, but cost is higher, and working (machining) efficiency is low.Therefore our inventor has invented heat spreader structures of the present utility model according to these situations.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art and a kind of novel heat spreader structures is provided.
For achieving the above object, the utility model adopts following technical scheme:
The heat spreader structures of chimeric high heat-conductivity conducting plastic cement in a kind of common heat conduction plastic cement, it comprises the first plastic cement main body of high heat-conductivity conducting plastic cement material and the second plastic cement main body of common heat conduction plastic cement material, described the first plastic cement main body is entrenched in the second plastic cement main body, described the second plastic cement main body is outside equipped with and the integrated some radiating fins of the second plastic cement main body, and common heat conduction plastic cement comprises common plastic cement and general heat conduction plastic cement.
Further, described the second plastic cement main body is local envelopment the first plastic cement main body.
Further, described the second plastic cement main body one end is bolted with the LED connector, and described LED connector is provided with the LED joint.
