Detailed description of the invention

About above-mentioned and other technology contents of the present utility model, feature and effect, in the middle of coordinating below and describing in detail with reference to the embodiment of accompanying drawing, can clearly present.

Refer to Fig. 1 to Fig. 3, be assembled on LED bulb 100 in external mode according to the external connection extended radiator structure 200 of the LED bulb of the utility model embodiment.

LED bulb 100 comprises cooling base 110, LED luminescence unit (not shown), drive plate lamp holder 120, lampshade 130 and insulation division 140.

Cooling base 110 have be positioned at relatively to first end 111 and the second end 112.LED luminescence unit comprises circuit board and at least one LED, and this LED luminescence unit is located at the second end 112 of cooling base 110.Lampshade 130 is PC lampshade, and it is also located at the second end 112 of cooling base 110, and covers LED luminescence unit.Insulation division 140 is located at the first end 111 of cooling base 110, and it is as the use of the insulation between cooling base 110 and drive plate lamp holder 120.The lamp holder that drive plate lamp holder 120 is joint geometry, it is positioned at the first end 111 of cooling base 110 via insulation division 140, and is electrically connected at LED luminescence unit.Refer to Fig. 3, LED bulb 100 can directly be installed on lamp socket 300 according to the joint categories of its drive plate lamp holder 120, for lighting LED luminescence unit.

External connection extended radiator structure 200 comprises male interface 210 and additional radiating tube 220.Male interface 210 is located at the outer wall of the cooling base 110 of LED bulb 100.Additional radiating tube 220 has heat radiation body 221, and its inwall is provided with threaded female interface 222, and additional radiating tube 220 can be according to this threaded female interface 222 and engaging with male interface 210 of can separating.

In the time that additional radiating tube 220 is engaged in the male interface 210 of LED bulb 100, additional radiating tube 220 stretches out along the direction of the first end 111 of the cooling base 110 of LED bulb 100, and additional radiating tube 220 does not limit its peripheral dimension and pattern.Therefore, according to the circumscribed radiator structure of LED bulb of the present utility model, its additional radiating tube 220 is assembled in the set male interface 210 of cooling base 110 outer walls of LED bulb 100 in external mode, to expand heat radiation length and the heat radiation external diameter of cooling base 110, that is increase the cooling surface area of cooling base 110.Thereby according to the circumscribed radiator structure of LED bulb of the present utility model, can promote the radiating effect of LED bulb, maintain the due brightness of LED bulb, and can be for the LED bulb of high wattage.
