The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the present invention is described in further detail.
Fig. 1 is the three-dimensional exploded view of the high-heat-dispersion LED bulb lamp 100 of first embodiment of the invention, and this high-heat-dispersion LED bulb lamp 100 comprises a plurality of led light sources 20, bulb housing 30, heating column 40, driver 50 and lamp holder 60.This heating column 40 is arranged on the top of this lamp holder 60, and this bulb housing 30 was the hemisphere cell-shell, was located at the top of this lamp holder 60, in this heating column 40 and these led light sources 20 are housed in.
Please refer to Fig. 1, this heating column 40 is the polygonal prism cylinder, comprises end face and a plurality of sidewall, and these led light sources 20 are arranged on the end face and sidewall of this heating column 40.The bottom of this heating column 40 is provided with heat transfer part 401, and this heat transfer part 401 is for protruding the truncated cone-shaped sidewall (as shown in Figure 1) of these heating column 40 sidewalls, and the external diameter at its minimum place is greater than the external diameter at these heating column 40 other positions.This heating column 40 is made such as borosilicate glass by the high-termal conductivity glass material.The end face of this heating column 40 and sidewall are provided with silver slurry metal line layer 404, this silver slurry metal line layer 404 can make these led light sources 20 on this heating column 40 be electrically connected with outside the realization, and should starch the good wet performance that metal line layer 404 utilizes glass and argent by silver, so that led light source 20 can directly be welded on the heating column 40, thereby reduce the thermal contact resistance of heat on heat conduction path that these led light sources 20 give out.
Please refer to Fig. 1 and Fig. 2, the bottom opening of this bulb housing 30 is provided with connecting portion 301 to heat transfer part 401 that should heating column 40, and the lateral wall of the inwall of this connecting portion 301 and this heat transfer part 401 is complementary.This connecting portion 301 is arranged on the bottom of this bulb housing 30, and this bulb housing 30 adopts high heat conduction borosilicate glass to make, and heat transfer glue and the heat transfer part 401 of this heating column 40 of this bulb housing connecting portion 301 by high thermal conductivity coefficient is thermally coupled.The lateral surface of this bulb housing connecting portion 301 is pasted (as shown in Figure 2) in the open top that is fixed on this lamp holder 60 by bonding agent.Because this bulb housing 30 all adopts high heat conduction borosilicate glass material with this heating column 40, therefore heat can conduct in identical heat-conducting quickly, and the heat transfer part 401 of this bulb housing connecting portion 301 and this heating column 40 is connected by the heat transfer glue of high thermal conductivity coefficient, can reduce the thermal contact resistance of this bulb housing connecting portion 301 and this heating column heat transfer part 401, make heat can be successfully be delivered on this bulb housing 30 and be dispersed into the air from this heating column 40.Because the connecting portion 301 of this bulb housing 30 all is made as truncated cone-shaped with the heat transfer part 401 of this heating column 40, can increase like this contact area of these bulb housing 30 connecting portions 301 and these heating column 40 heat transfer parts 401, more be conducive to the conduction of heat.
Please refer to Fig. 1, the bottom of this heating column 40 also is provided with a slot to make way (not shown), this driver 50 is arranged in the space of these heating column 40 bottom slots to make way and 60 formation of this lamp holder, and this silver slurry metal line layer 404 is electrically connected by this driver 50 and outside the realization.
During work, the heat that these led light sources 20 on this heating column 40 distribute is delivered on this bulb housing 30 by this heating column heat transfer part 401, because this bulb housing 30 all adopts high heat conduction borosilicate glass material with this heating column 40, heat transmits in identical material radiating efficiency is improved widely, and this bulb housing connecting portion 301 adopts the heat transfer glue of high thermal conductivity coefficient to be connected with this heating column heat transfer part 401, can reduce the thermal contact resistance on the heat conduction path, make heat can be successfully be delivered on this bulb housing 30 from this heating column 40 and be dispersed into the air.
In sum, this high-heat-dispersion LED bulb lamp 100 does not arrange independent radiating piece, but by the bottom at this heating column 40 heat transfer part 401 is set, and the heat transfer part 401 of the bottom of this bulb housing 30 and this heating column 40 is thermally coupled, so that the heat that led light source 20 produces on the heating column 40 can be delivered on the bulb housing 30 by heating column 40, diffuse to space outerpace from bulb housing 30 again.Can not realize heat radiation owing to not needing as prior art, to arrange a plurality of fin, so high-heat-dispersion LED bulb lamp 100 of the present invention has advantages of simple in structure and good heat dissipation effect.
Understandable, the side wall surface number of heating column and the number of led light source can design according to the lighting angle of needs.
Above these only are preferred embodiment of the present invention, and in order to limit the present invention, any those skilled in the art can not work as the technology contents that utilizes above-mentioned exposure and make the equivalent embodiment of a little change for changing on an equal basis within not breaking away from this programme technical scope.In every case for breaking away from the technical solution of the present invention content, any modification of above embodiment being made according to the technology of the present invention essence, be equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
