Embodiment
Below by way of specific embodiment, the present invention will be described in detail:
Embodiment one:
Fig. 1 is the exploded view of LEDbulb lamp first embodiment of the present invention, which includes bulb housing 10, light source board 20 and lamp cap 30, the bottom cover of the bulb housing 10 is arranged on the lamp cap 30, which is arranged in the bulb housing 10, the lamp Blister 10 was hemisphere bubble shell structure.Heat-conducting piece 40 is further included, which is made of metal material, which is set It is thermally connected in the top of the heat-conducting piece 40 and the heat-conducting piece 40, first, the heat which produces can be delivered to the heat conduction On part 40.
Please refer to Fig.1, the top of the lamp cap 30 is provided with connecting seat 31, which is arranged on the connecting seat 31. In the present embodiment, the bottom of the heat-conducting piece 40 is arranged at the top of the connecting seat 31 and the lamp cap 30 forms power supply cavity, the electricity Driving power is provided with source chamber body.The bottom of the lamp cap 30 is equipped with screw socket lamp housing 32, and the screw socket lamp housing 32 is by metal material system Into the connecting seat 31 is made from a material that be thermally conductive, which is thermally connected with the screw socket lamp housing 32 and the heat-conducting piece 40 at the same time, makes A part of heat obtained on the heat-conducting piece 40 can be delivered on the connecting seat 31, be further dispersed into by the connecting seat 31 outer Portion space.The connecting seat 31 can pass through ultrasonic bonds with the bulb housing 10.In the present embodiment, which is equipped with connection Hole 311, further includes screw (not shown), these screws are attached to the connecting seat 31 after passing through the light source board 20 and the heat-conducting piece 40 Connecting hole 311 in, the heat-conducting piece 40 is spacing to be fixed between the light source board 20 and the connecting seat 31, which is consolidated Due on the connecting seat 31, the light source board 20 is fixed on the heat-conducting piece 40.
Wherein, 11 madial wall of bottom of the bulb housing 10 and the lateral wall of the heat-conducting piece 40 are thermally connected.Specifically, the light bulb The bottom 11 of shell 10 is made of elastic material, and the bottom 11 of the bulb housing 10 is flexibly socketed in the lateral wall of the heat-conducting piece 40 On so that in heat transfer on the heat-conducting piece 40 to the bottom 11 of the bulb housing 40, further dissipated by the bulb housing 10 It is dealt into exterior space.
Please refer to Fig.1, in the present embodiment, further include fastener 50, which includes side ring 51, is set on the side ring 51 There is fluting 511 so that the side ring 51 has elasticity, the side ring 51 of the fastener 50 is sheathed on the lateral wall of the heat-conducting piece 40, should The bottom inside wall of bulb housing 10 is pressed on the side ring 51 and is thermally connected with the side ring 51.In this way, the side ring 51 is led between this Between warmware 40 and the bottom 11 of the bulb housing 10, due to the elastic reaction of the side ring 51, the bottom 11 of the bulb housing 10 can be tight Close contacts with the heat-conducting piece 40 so that the heat on the heat-conducting piece 40 can be delivered to the light bulb by the fastener 51 faster On shell 10.
