The specific embodiment
The specific embodiment that the utility model adopts will and attachedly be graphic and be further described by following embodiment.
Consult simultaneously Fig. 1 to shown in Figure 4, Fig. 1 shows that the bulb lamp heat abstractor of an embodiment of the present utility model is in conjunction with the stereogram of bulb lamp, Fig. 2 is the side cutaway view that shows the bulb lamp heat abstractor of an embodiment of the present utility model, Fig. 3 is the upper pseudosection that shows the bulb lamp heat abstractor of an embodiment of the present utility model, Fig. 4 be show an embodiment of the present utility model the bulb lamp heat abstractor radiating top plate on look face figure.
As shown in the figure, among the embodiment of the present utility model, a bulb lamp heat abstractor 2 is to be incorporated into a bulb lamp 1.
In the present embodiment, bulb lamp 1 comprises an illuminating circuit section 11, one drive circuit section 12, reaches a lampshade 13.Illuminating circuit section 11 comprises a luminescence unit 111, and is electrically connected on drive circuit section 12, and lampshade 13 covers in the top of illuminating circuit section 11.Wherein, but luminescence unit 111 can be arbitrary luminescence component, and it is subjected to drive circuit section 12 luminous with electric energy driven light emission circuit part 11, example, and luminescence unit 111 is a LED luminescence unit, and drive circuit section 12 is a led drive circuit.
Bulb lamp heat abstractor 2 comprises a heat radiation outer ring body 21.Dispel the heat outer ring body 21 thermo-contacts in the illuminating circuit section 11 of bulb lamp 1, and be located in the outer circumferential side of drive circuit section 12.The gap that is separated by between heat radiation outer ring body 21 and the drive circuit section 12, this gap consists of a heat dissipation channel 22.One end of heat dissipation channel 22 is communicated in the illuminating circuit section 11 of bulb lamp 1, and the other end then extends and is communicated to the bulb lamp outside.In addition, above-mentioned mentioned thermo-contact can be that two modular constructions directly mutually attach or between the two with arbitrary gas that helps to dispel the heat, liquid, solid-filling it, example, thermal grease.
By above-described structure, the heat dissipation channel 22 of bulb lamp heat abstractor 2 can intercept the drive circuit section 12 of bulb lamp 1 and the heat transmission between the illuminating circuit section 11, and both are not directly impacted mutually by other cooling mechanism.In addition, an end of heat dissipation channel 22 and bulb lamp 1 exterior can be utilized cross-ventilation, and the heat with producing in the drive circuit section 12 of bulb lamp 1 and illuminating circuit section 11 courses of work is dissipated to outside the bulb lamp 1, improves by this whole radiating efficiency.
