The beneficial effects of the utility model are: by at the light source cavity of light fixture and drive between the cavity heat shield is set, the heat that prevents to drive in the cavity flows in the light source cavity, even adopt powerful light source like this, its luminous heat that produces also can not influence the work of electric appliance component, can solve the interactional problem of temperature between light source and the electric appliance component, prolong the service life of light fixture, and it is safer to make that light fixture uses.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the fitting structure schematic diagram of the utility model preferred embodiment.
The specific embodiment
The fitting structure of the utility model preferred embodiment as shown in Figure 1, it comprises the spill housing 10 with opening, is provided with Transparent Parts 11 at the opening part of housing 10.This light fixture also comprises the reflection shield 20 that is contained in the housing 10, and the edge of reflection shield 20 is fixedly connected on housing 10 opening parts; The medial surface of reflection shield 20 and Transparent Parts 11 form the light source cavity 70 that accommodates light source 30; Form the driving cavity 60 that accommodates the electric appliance component that is used for driving light source between reflection shield 20 lateral surfaces and housing 10 bottoms, electric appliance component comprises one or more in electric capacity 52, ballast 51 and the trigger 53.Be provided with the heat shield 40 that the heat that is used to prevent to drive in the cavity 60 and the heat in the light source cavity 70 circulate mutually in reflection shield 20 bottoms.Even adopt powerful light source 30 like this, its luminous heat that produces can not influence the electric appliance component operate as normal yet, can solve the interactional problem of temperature between light source 30 and the electric appliance component, prolong the service life of light fixture, and it is safer to make that light fixture uses.
In the foregoing description, light source 30 comprises illuminating part 31 and connecting portion 32, is provided with installing hole in reflection shield 20 bottoms, and the connecting portion 32 of light source 30 passes installing hole and is electrically connected with electric appliance component in driving cavity 60.Heat shield 40 comprises cover body portion 41 that covers on the connecting portion 32 and the fixed part 42 that is connected reflection shield 20 inboards.When light source 30 is luminous, integral body all can produce big heat, cause extending into light source connecting portion 32 heat radiations that drive cavity 60 and influence electric appliance component work, and connecting portion 32 also can dispel the heat to driving in the cavity 60 with the joint gap place of reflection shield 20, the heat that adopts heat shield 40 effectively light source 30 to be distributed is stayed in the light source cavity 70, is unlikely to influence the work of electric appliance component.
