Description
Technical field
The utility model belongs to field of illuminating device, relates in particular to a kind of indoor hoisting lighting for industrial and mineral factory building.
Background technology
Granted publication day is on January 8th, 2014, and Granted publication number is in the Chinese utility model patent of CN203384939U, discloses a kind of LED bulkhead lamp capable, and its concrete structure as depicted in figs. 1 and 2.It comprises lamp holder 1, connecting piece of lamp cap 2, lamp housing 3, heat conduction power source cavity 4, heat transfer component 5 and the LED wiring board connecting successively, and heat conduction power source cavity 4 one end and lamp housing 3 fix as one, and the other end and heat transfer component 5 fix as one; Its lamp housing is a bowl-shape hollow shell, by light cover 9, set of lenses and light-passing board is fixed on to its front end, and lamp housing rear end is provided with isometrical section that contacts with heat conduction power source cavity outer surface.Conducting-heat elements 5 one sides described in it are plane, are provided with ring-type heat conduction shirt rim 5-2 in its neighboring, between the outer surface of ring-type heat conduction shirt rim and the inner surface of lamp housing 3, for face contact type connects; On the surface of lamp housing, be coated with heat loss through radiation dope layer.
This technical scheme is owing to having abandoned the fin slices radiator of traditional LED bulkhead lamp capable heaviness, by increasing the lateral area of ring-type heat conduction shirt rim on conducting-heat elements, making it increases greatly with the contact area of lamp housing, form face contact type structure, make full use of the area of dissipation of lamp housing, improved heat transfer efficiency, increased heat passage, more heat can be from the sidewall conduction past of conducting-heat elements; It is by adding heat-flash conduction and processing at the heat loss through radiation on lamp housing surface, from thermal source, start to get through whole heat passage, make heat be unlikely to accumulate in certain corner, make full use of area of dissipation, reach good radiating effect, also can make to wait a light fixture to there is better optical property, its fairshaped lamp housing design, make the handsome in appearance of whole light fixture, be adapted at exhibition center, the occasions such as airport are used.
Its internal heat conducting path as shown in Figure 2, one end of heat conduction power source cavity 4 fixes as one through securing member and heat transfer component 5, its other end fixes as one through securing member and lamp housing 3 and connecting piece of lamp cap (not shown), as seen from the figure, the lateral wall of heat conduction power source cavity contacts with the madial wall of lamp housing lower semisection (being aforesaid isometrical section), be face contact type annexation between the two, directly the heat on heat transfer component is led to part under lamp housing, reduce thermal resistance between the two, strengthen heat-transfer effect.
In figure, arrow is depicted as heat conduction orientation: heat passes through therefrom mind-set edge-diffusion of heat transfer component on the one hand, by ring-type heat conduction shirt rim (being also called flanging), be delivered to lamp housing, heat, from conducting-heat elements central interior going down, is transmitted to lamp housing the latter half by middle driving power chamber on the other hand.Final all heats are by the external distribute heat of radiation paint layer of lamp housing outer surface.
But find in actual use, adopt the LED bulkhead lamp capable of this structure, in the long use procedure of light fixture, the heat of LED wiring board is transmitted on shell 3 through heat transfer component 5, heat conduction power source cavity 4, and stop after energising at light fixture, shell and heat transfer component are cooling gradually under the effect of surrounding air, make heat transfer component and lamp outer casing produce expanding with heat and contract with cold repeatedly.
Because heat conduction power source cavity is metal material, and its height/length is fixed, repeated expanding with heat and contract with cold between aforementioned ring-type heat conduction shirt rim and lamp housing, caused the outer surface of its ring-type heat conduction shirt rim to change with the tightness degree that contacts between lamp housing inner surface, when serious, even can cause the heat-conducting glue of filling between ring-type heat conduction shirt rim lateral surface surface and lamp housing medial surface surface, because changing, contact tightness degree between the two reduces its heat-conducting effect, cause the thermal resistance between lateral surface surface, ring-type heat conduction shirt rim and lamp housing medial surface surface to rise, hindered the unimpeded of whole light fixture heat dissipation channel, and then affect service life of whole light fixture.
