The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
The utility model provides a kind of lighting device, can adopt the LGP of non-rectangle.
The lighting device of the utility model comprises a circuit board, a LGP and a plurality of luminescence component.The shape non-rectangle of LGP.Luminescence component is disposed on the circuit board and with circuit board and electrically connects.Luminescence component is around LGP, and the bright dipping side of luminescence component is towards LGP.
In one of the utility model embodiment, LGP be shaped as circle, pentagon, octagon or irregular shape.
In one of the utility model embodiment, luminescence component is that symmetric points are the point symmetry distribution with the geometric center of LGP.
In one of the utility model embodiment, LGP is disposed on the circuit board.In addition, circuit board for example has an opening, and LGP covers opening.In addition, circuit board for example be metal-cored circuit board (metal core printed circuit board, MCPCB).
In one of the utility model embodiment, circuit board is around LGP, and luminescence component is between circuit board and LGP.
In one of the utility model embodiment, luminescence component is a light emitting diode.
Based on above-mentioned, in the lighting device of the utility model, the LGP and the luminescence component of non-rectangle are configured on the circuit board jointly, and the bright dipping side of luminescence component is towards LGP.Therefore, the allocation position of luminescence component can change with the shape of LGP easily.
The lighting device of the utility model may be used on many different illumination application fields, for example, the backlight module of liquid crystal indicator, the lighting source that growth and development of plants uses is provided or decorates with lighting device or the like.Because the novel designs of the leaded light of the lighting device of the utility model mechanism makes lighting device that the light-emitting zone of different shape can be provided.Below, with lifting the lighting device that embodiment further specifies the utility model.
Fig. 1 is the sketch map of the lighting device of the utility model one embodiment.Please with reference to Fig. 1, the lighting device 100 of present embodiment comprises a circuit board 110, a LGP 120 and a plurality of luminescence component 130.LGP 120 is disposed on the circuit board 110 with luminescence component 130.Luminescence component 130 also electrically connects to produce light and from the bright dipping of bright dipping side with circuit board 110.The shape non-rectangle of LGP 120.The bright dipping side of luminescence component 130 is towards LGP 120, with from the side light inlet of LGP 120 and from end face 122 bright dippings of LGP 120.
Because the bright dipping side of the luminescence component 130 of present embodiment is towards LGP 120, no matter therefore the shape of LGP 120 why, as long as the light that the position of adjustment luminescence component 130 on circuit board 110 can let luminescence component 130 send gets into LGP 120 smoothly.The luminescence component 130 of present embodiment is around LGP 120, that is the light that luminescence component 130 sends is to get into LGPs 120 from a plurality of directions, and then converts uniform surface light source into by LGP 120.For example, luminescence component 130 is that symmetric points are the point symmetry distribution with the geometric center of LGP 120.The geometric center of the LGP 120 of present embodiment is exactly the center of circle of LGP 120.The luminescence component 130 and the LGP 120 of present embodiment are disposed on the circuit board 110 equally, so circuit board 110 need not cooperate the shape of LGP 120 and bend, can reduce design and the difficulty of assembling, and also can reduce whole cost.
The LGP 120 of present embodiment be shaped as circle; But the shape of LGP also can be polygon or an irregular shape oval, that five limits are above in other embodiments; For example the LGP of Fig. 3 be shaped as octagon, and the LGP of Fig. 4 be shaped as pentagon.In addition, the luminescence component of present embodiment 130 is an example with the light emitting diode, but is not limited to this.Luminescence component 130 can adopt surface mount technology or other technology (for example welding) to be bonded to circuit board 110.On the other hand, can improve and reduce luminous efficiency in the temperature of the back luminescence component 130 that works long hours.The circuit board 110 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 130 high efficiency heat radiation approach to help quick heat radiating; And then increase luminescence component 130 when work reliability and obtain desirable luminous efficiency, also can increase the structural strength of circuit board 110.The circuit board 110 of present embodiment also can keep an opening 112 below the zone of LGP 120 configurations, so that from opening 112 bright dippings, but so that the end face 122 of LGP 120 and all bright dippings of bottom surface 124.The shape of opening 112 can be done any variation on demand.
Fig. 5 is the sketch map of the lighting device of another embodiment of the utility model.Please with reference to Fig. 5, the lighting device 200 of present embodiment is similar with the lighting device 100 of Fig. 1, only introduces both difference places at this.The circuit board 210 of present embodiment is around LGP 220, and luminescence component 230 is between circuit board 210 and LGP 220.In other words, luminescence component 230 is the pattern of top light emitting.
In sum, in a kind of lighting device of the utility model, LGP and luminescence component all dispose on the same circuit board, and the bright dipping side of luminescence component is towards LGP.Therefore, no matter the shape of LGP why, as long as the position of adjustment luminescence component on circuit board can provide LGP required light smoothly, and then reduces the cost of the lighting device of the utility model.In the another kind of lighting device of the utility model, circuit board can be around the LGP of arbitrary shape, and design can reduce cost easily.
Though the utility model discloses as above with embodiment; Right its is not in order to limit the utility model; Has common knowledge under any in the technical field; In spirit that does not break away from the utility model and scope, when can doing a little change and retouching, so the protection domain of the utility model is when looking being as the criterion that the accompanying Claim scope defined.
