The specific embodiment
Below embodiment of the present utility model is elaborated:
As shown in Figure 1, LED light fixture described in the utility model, comprises lamp body 10, on described lamp body 10, has LED area source 20, also comprises lampshade 60.As shown in Figure 2,3, described lampshade 60 has for covering cover mouth 62 and the light-emitting window 61 of described LED area source 20, covers reflectorized material and form the first reflective surface on described lampshade 60 madial walls.If Fig. 4 is to as shown in Fig. 6, they be described lampshade at the cutaway view at A-A place, the area of LED area source 20 is little described in the Area Ratio of described light-emitting window 61.
The utility model covers LED area source 20 with lampshade 60, on lampshade 60 madial walls, reflectorized material is set, on lampshade 60, offer the light-emitting window 61 that Area Ratio LED area source 20 is little, as required light-emitting window 61 positions can be set flexibly, the light that LED area source 20 produces arrives light-emitting window 61 by direct projection and reflection, by light-emitting window 61, penetrated, the light source optical path producing by changing LED area source 20, luminous the converging by small size light-emitting window 61 of large-area LED area source 20 irradiated, when light-emitting window 61 more hour, be the equal of the spot light with direction of illumination, this light illumination is effective, utilizing emitted light has light shape, when especially automobile lamp adopts LED light fixture of the present invention, because utilizing emitted light has light shape, travel radiation response is good, light can directly not injected in passerby's eyes, can reduce traffic accident occurs.The excess Temperature producing while simultaneously avoiding small size light source luminescent to irradiate affects the LED lamp life-span.
As shown in Figure 1, in the present embodiment, have wire guide 40 on lamp body 10, power supply is powered to lamp body 10 by wire guide.What be connected with described lamp body 10 heat conduction has a radiator structure, and wherein radiator structure comprises radiating copper sheet and the fan being connected with radiating copper sheet, and radiating copper sheet is connected with lamp body 10 heat conduction, and the heat that lamp body 10 is produced is passed to radiating copper sheet, through fan auxiliary heat dissipation.Described radiator structure overcoat has sleeve 50, offers louvre 51 on sleeve 50, with sleeve 50, radiating copper sheet and fan is wrapped up, and makes lamp body 10 overall structure better appearance.In the present embodiment, the shape of described cover mouth 62 is larger than the shape of described LED area source 20, on described lamp body 10 corresponding between described LED area source 20 and described cover mouthfuls 62, cover reflectorized material and form the second reflective surface, the light source that described LED area source 20 produces constantly reflects and launches by light-emitting window 61 in the first reflective surface and the second reflective surface, reduce the loss of light in lampshade 60 internal reflection processes as far as possible, strengthen the radiation response of light-emitting window 61.In an embodiment, the shape of described cover mouth 62 and the shape of described LED area source 20 are suitable therein.In the present embodiment, lamp body 10 is provided with keeper 30, by setting up keeper 30, can prevent lamp body 10 rotations, avoids affecting radiative light path.
As shown in Figure 6, described light-emitting window 61 forms for being connected with second channel section 64 by first passage section 63 with the passage between described cover mouth 62, and described first passage section 63 is straight section, and passage internal diameter remains unchanged, and radiative smooth shape is fixed.Passage in described second channel section 64 is the expanding reach gradually towards cover mouth, and internal diameter expands gradually towards cover mouthful 62 directions.Therein in a kind of embodiment, between the light-emitting window 61 of described lampshade 60 and described cover mouthfuls 62, be filled with transparent silica gel, transparent silica gel is the equal of optical fiber, can reduce the light decay in lampshade 60, enhancing illuminating effect.
