[specific embodiment]
In Fig. 1 to Fig. 7 and the utility model embodiment 1LED bulb lamp radiator shown in Figure 9, LED bulb lamp radiator 5 is up big and down small back taper, comprises the installation heat transfer part that is positioned at end face, the radiating part of side and the installation location division of lower end.
The end face that heat transfer part 501 is installed is a spline shape.
Radiating part comprises 8 interior heat sink strips 503 and 8 outer heat sink strips 502, and interior heat sink strip 503 and outer heat sink strip 502 are vertically arranged.The upper end of outer heat sink strip 502 is connected with the tooth top portion of spline shape end face 501, and the upper end of interior heat sink strip 503 is connected with the teeth groove portion of spline shape end face 501; Radial misalignments forms the inner externally radial clearance Δ of heat dissipation ventilation of radiator between interior heat sink strip 503 and the outer heat sink strip 502.
All vertical heat sink strips 502 and 503 fold the installation location division 504 that forms circle or regular polygon in the lower end.
As shown in Figure 9, the material of radiator is an aluminium metal sheet, cuts out with the aluminium alloy plate of full wafer to be stamped to form, and it is star that radiator launches the back.
The radial clearance Δ that radial misalignments formed between heat sink strip 503 and the outer heat sink strip 502 in radiator in the foregoing description mainly relied on carries out ventilation and heat, and circular gap is less.As strengthening the inside and outside draught area of radiator, interior heat sink strip 503 and outer heat sink strip 502 can design narrowlyer, make the bigger circular gap of existence between the adjacent heat sink strip.
