Background technology
Traditional high power light fixture adopts fin or die casting aluminium radiating mode that heat of light source is derived more, portioned product has also coordinated heat pipe, increase heat transfer path, but power is higher, radiating effect is lower, the decline in advance of serious caused light source, reduce the life-span, although can make up by modes such as the height of increase radiator, diameter, width, in the situation that guaranteeing its heat radiation result, the weight of its whole light fixture will significantly increase.
Utility model content
The purpose of this utility model is to provide a kind of good heat dissipation effect, and can reduce the heat abstractor of the LED encapsulating structure of whole lamp weight.
The utility model is achieved in that a kind of heat abstractor of LED encapsulating structure, comprise for absorb LED integrated optical source produce heat heating column and for the radiator of walking that the heat of heating column is fallen apart, described heating column is arranged in radiator, axial one end of heating column contacts with LED particle, described radiator is made up of with the multiple heat sinks that are arranged on the different radial direction of heat-conducting metal cylinder periphery the heat-conducting metal cylinder that is socketed in heating column outside, between adjacent heat sink, be reserved with gap, the side of each heat sink is radially provided with by interior the corrugated structure that multiple tracks is in axial direction extended outward successively.
Further prioritization scheme is: the side, the left and right sides of each heat sink is equipped with corrugated structure, and it is symmetrical to be arranged at the corrugated structure of side, each heat sink left and right sides.
Further prioritization scheme is: the periphery of heat-conducting metal cylinder is provided with the slot of multiple heat sinks that are used for pegging graft.
Further prioritization scheme is: in each heat radiation plate body, be radially provided with successively outward multiple cavitys that in axial direction extend by interior.
Further prioritization scheme is: axial one end of described heating column is provided with the copper coin for contacting LED particle, and heating column is made up of the copper pipe of the in-built liquid object that is useful on heat absorption of body.
The advantage of the heat abstractor of the utility model LED encapsulating structure is: 1, the side of heat sink is radially provided with by interior the corrugated structure that multiple tracks is in axial direction extended outward successively, make the heat of light fixture generation along the axial and Radial Flow of heat sink, can realize the axial convection current of radiator surrounding air, area of dissipation has effectively extended, the heat-sinking capability that has strengthened radiator makes radiating effect better, and greatly reduce the weight of radiator, the overall weight of light fixture is alleviated, there is the effect that improves the LED light source life-span; 2, heat sink is plugged on heat-conducting metal cylinder by slot, conveniently replaced after one of them heat sink damages.
