Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the blast structural representation that has the LED lamp group of heat abstractor of the present utility model;
Fig. 2 is the structural representation that has first kind of embodiment of LED lamp group of heat abstractor of the present utility model;
Fig. 3 is the structural representation that has second kind of embodiment of LED lamp group of heat abstractor of the present utility model;
Fig. 4 is the structural representation that has the third embodiment of LED lamp group of heat abstractor of the present utility model.
The specific embodiment
Be illustrated in figure 1 as the blast structural representation that has the LED lamp group of heat abstractor of the present utility model.Comprise pcb board 2, LED fluorescent tube 202, the pin of described LED fluorescent tube 202 is contained on the described pcb board 2 and passes described pcb board 2 and forms a plurality of leg 201 at its back side, also comprise a heat abstractor 1, heat abstractor 1 is made of heat sink material, matching of the shape of heat abstractor 1 and pcb board 2, heat abstractor 1 closely contacts with the back side of pcb board 2.Described heat abstractor 1 is provided with the leg groove 101 that is used to hold described leg 201 with the contacted one side in the back side of described pcb board 2, and leg 201 is just in time corresponding after installing does not contact in leg groove 101 and with heat abstractor 1.Between pcb board 2 and heat abstractor 1, also be provided with one deck dielectric film 3.Pcb board 2 and described heat abstractor 1 are connected and fixed by first screw 4.Wherein heat abstractor 1 can be the sheet assembling structure that is made of aluminium section bar.
Be illustrated in figure 2 as the structural representation that has first kind of embodiment of LED lamp group of heat abstractor of the present utility model, wherein leg groove 101 is a strip structure.Leg groove 101 matches with the arrangement position of leg 201, and a leg groove 101 holds row's leg 201, and such is relatively simple for structure, and energy effective simplification production technology reduces cost.
