The specific embodiment

Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.

Referring to Fig. 1 and Fig. 2, a kind of LED bulb lamp, the lamp body that comprises standard lamp socket 1, forms by upper body 2 and heat dissipating housing 3, the ball that is connected to heat dissipating housing 3 front ends bubble 4 and be installed in the LED lamp group in the lamp body.

2 rear ends, upper body fix with standard lamp socket 1 and are connected, and heat dissipating housing 3 is threaded in the front end of upper body 2.

Referring to Fig. 3 and Fig. 4, heat dissipating housing 3 adopts ceramic material, comprises an internal ring wall 301 and an external annulus 302.Between internal ring wall 301 and external annulus 302, connect through partition 303.Partition 303 is the whole body and evenly distributes, and adjacent two partitions and internal ring wall 301 form heat dissipation wind channel 304 with external annulus 302.Stretch out the external annulus 302 of heat dissipating housing 3 in the rear end of the internal ring wall 301 of heat dissipating housing 3, on extension, be provided with screw thread and be connected with the front end of upper body 2 through this part.

The internal ring wall 301 of heat dissipating housing 3 is cylinder ring, its front end retraction external annulus 302, and on the front end of internal ring wall 301, be provided with a stationary barrier 305, therefore the front end at heat dissipating housing 3 forms a lamp chamber.In the middle of stationary barrier 305, be provided with a line hole 306.These stationary barrier 305 somewhat larger in diameter are in internal ring wall 301.The aluminium base 5 of LED lamp group and the outside of stationary barrier 305 are close to fixing, and driving power 7 is installed in the internal ring wall 301.And be electrically connected through line hole on the stationary barrier 305 306 and LED lamp group.

The external annulus 302 of heat dissipating housing 3 roughly is sphere, and the heat dissipation wind channel 304 that itself and partition 303, internal ring wall 301 form is variable cross-section.In fact, the external styling of this external annulus 302 can have many variations, also many design can be arranged, to beautify the outward appearance of LED bulb lamp.And in view of heat dissipating housing 3 employing ceramic materials, this design can be the blue and white porcelain pattern.

In the present embodiment, for ease of the shaping processing of heat dissipating housing 3, this heat dissipation wind channel 304 is the straight channel of variable cross-section, but this heat dissipation wind channel also can be a helical duct, and its spiral air flow makes radiating effect better.
