The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
The present invention provides a kind of lighting device, and its periphery has light source.
Lighting device of the present invention comprises a housing, a leaded light bar and one first light source.The leaded light bar is disposed at the periphery of housing.First light source is disposed at a light inputting end of leaded light bar.
In one of the present invention embodiment, housing is discoid.
In one of the present invention embodiment, the leaded light bar is acryl bar or optical fiber.
In one of the present invention embodiment, first light source is a light emitting diode.
In one of the present invention embodiment, the leaded light bar is divided into multistage.First light source comprises a plurality of luminescence components.At least one luminescence component of configuration between each section of leaded light bar.
In one of the present invention embodiment, lighting device more comprises a secondary light source, is disposed at housing and is centered on by the leaded light bar.In addition, secondary light source for example comprises a circuit board, a LGP and a plurality of luminescence component.Luminescence component is disposed on the circuit board and with circuit board and electrically connects.The bright dipping side of luminescence component is towards LGP.In addition, LGP for example is disposed on the circuit board.In addition, circuit board for example be metal-cored circuit board (metal core printed circuit board, MCPCB).
Based on above-mentioned, the leaded light bar and the light source of the periphery through being disposed at housing, the present invention's lighting device can be luminous at periphery.
Fig. 1 is the front view of the lighting device of one embodiment of the invention.Please with reference to Fig. 1, the lighting device 100 of present embodiment comprises a housing 110, a leaded light bar 130 and one first light source 140.Leaded light bar 130 is disposed at the periphery of housing 110.First light source 140 is disposed at a light inputting end 130A of leaded light bar 130.
The light that first light source 140 provides gets in the leaded light bar 130 from the light inputting end 130A of leaded light bar 130, and light is enclosed around housing 110 1 along leaded light bar 130 by the guiding of leaded light bar 130.Simultaneously, light also outwards penetrates at each section of leaded light bar 130, to reach the purpose that light is provided at the periphery of lighting device 100.Through the leaded light bar 130 and first light source 140, the lighting device 100 of present embodiment can be luminous at periphery.
The lighting device 100 of present embodiment can more comprise a secondary light source 120, is disposed at housing 110 and is centered on by leaded light bar 130.Secondary light source 120 provides light in most of zone of lighting device 100, and is good with uniform Luminance Distribution.Through suitably design, the leaded light bar 130 and first light source 140 can remedy secondary light source 120 maybe be in the more weak problem of the brightness of periphery, and then promotes the uniformity of the Luminance Distribution of lighting device 100.Perhaps, first light source 140 can be different with the wavelength and/or the brightness of the light that secondary light source 120 provides, and supply the user to select to light separately first light source 140 with secondary light source 120 or light both simultaneously, and the light of different wave length also has decorative effect.
The secondary light source 120 of present embodiment comprises a circuit board 122, a LGP 124 and a plurality of luminescence component 126.LGP 124 is disposed on the circuit board 122 with luminescence component 126.Luminescence component 126 also electrically connects to produce light and from the bright dipping of bright dipping side with circuit board 122.The bright dipping side of luminescence component 126 is towards LGP 124, with from the side light inlet of LGP 124 and from the end face bright dipping of LGP 124.Because the bright dipping side of the luminescence component 126 of present embodiment is towards LGP 124, no matter therefore the shape of LGP 124 why, as long as the light that the position of adjustment luminescence component 126 on circuit board 122 can let luminescence component 126 send gets into LGP 124 smoothly.The luminescence component 126 and the LGP 124 of present embodiment are disposed on the circuit board 122 equally, so circuit board 122 need not cooperate the shape of LGP 124 and bend, can reduce design and the difficulty of assembling, and also can reduce whole cost.
On the other hand, can improve and reduce luminous efficiency in the temperature of the back luminescence component 126 that works long hours.The circuit board 122 of present embodiment can adopt metal-cored circuit board.Metal-cored circuit board is aluminium flake or other thermal conductive metal plate that in the centre, buries a whole layer; Can provide luminescence component 126 high efficiency heat radiation approach to help quick heat radiating; And then increase luminescence component 126 when work reliability and obtain desirable luminous efficiency, also can increase the structural strength of circuit board 122.
In other embodiments, secondary light source 120 also can be the light source of fluorescent tube or other form.
The housing 110 of present embodiment is discoid, so leaded light bar 130 also surrounds into circle.Certainly, housing 110 also can be rectangle, triangle or other arbitrary shape.The leaded light bar 130 of present embodiment can be acryl bar, optical fiber or other suitable leaded light component.In addition, suitable light emitting structures can be designed in the surface of leaded light bar 130, to guide light that first light source 140 provides in position bright dipping that the designer wants.First light source 140 of present embodiment can be light emitting diode or other luminescence component.
Fig. 2 is the front view of the lighting device of another embodiment of the present invention.Please with reference to Fig. 2, the lighting device 102 of present embodiment is similar with the lighting device 100 of Fig. 1, and difference is in lighting device 102 and has multistage leaded light bar 132, and first light source comprises a plurality of luminescence components 142.Luminescence component 142 of configuration between each section leaded light bar 132.Adopt the leaded light bar 132 of multistage to help to promote the uniformity of the peripheral brightness of lighting device 102, and the wavelength of each luminescence component 142 and/or brightness also can be different to increase variability.
In sum, in the present invention's lighting device, the leaded light bar and first light source that are disposed at the periphery of housing provide periphery luminous function.Therefore, the present invention's lighting device can provide in the periphery and have variational light source.
Though the present invention discloses as above with embodiment; Right its is not in order to limit the present invention; Has common knowledge under any in the technical field; In spirit that does not break away from the present invention and scope, when can doing a little change and retouching, so the present invention's protection domain is when looking being as the criterion that accompanying Claim book scope defined.
