Embodiment 1
Fig. 1 is the front view of the thin straight down light source device 100 of the utility model embodiment 1.Fig. 2 is the exploded view of Fig. 1.Please refer to Fig. 1 and Fig. 2, the thin straight down light source device 100 of the present embodiment comprises a LGP 200, a light-reflecting sheet 300, a backboard 400 and at least one lamp bar 500.
The first surface 210 that LGP 200 comprises relative configuration and second 220, first surface 210 has a plurality of exhibition light grooves 230, and these exhibition light groove 230 compartment of terrains are arranged on the first surface 210 of LGP 200.Backboard 400 comprises a plurality of the first perforations 430 and relative the 3rd 410 of configuring and fourth face 420.These first perforations 430 are connected respectively the 3rd 410 and fourth face 420 of backboard 400.Light-reflecting sheet 300 clampings are between second 220 of LGP 200 and backboard 400 the 3rd 410.Light-reflecting sheet 300 also has a plurality of the second perforations 310.These second perforations 310 and the first perforation 430 are superimposed each other, and the second perforation 310 is all aimed at exhibition light groove 230 with the first perforation 430.Lamp bar 500 comprises a circuit board 510 and at least one light-emitting component 520.Circuit board 510 is stacked at the fourth face 420 of backboard 400, and light-emitting component 520 is fixedly arranged on circuit board 510, at least stretch in the first perforation 430, and luminous towards LGP 200.
Fig. 3 is that Fig. 1 is along the cutaway view of 3-3.As shown in Figure 3, so, in the design due to the utility model thin straight down light source device 100, backboard 400 need, in order to place the chase of lamp bar 500, not have the inconsistent problem of the different chase degree of depth.In addition, because the fourth face 420 of the backboard 400 of this novel slim directly-down light source device 100 is substantially flush, when circuit board 510 fits in the fourth face 420 of backboard 400, can allow these light-emitting components 520 roughly the same with the space D of LGP 200, help the laminating degree unification of 200 of light-emitting component 520 and LGPs.Again because backboard 400 does not need to arrange in order to place the chase of lamp bar 500, the 3rd 410 of backboard 400 can complete support light-reflecting sheet 300, does not need extra provide the structural support, to avoid light-reflecting sheet 300 to occur because of the problem that is subject to thermal softening and hangs down into chase.
Specifically, as shown in Figure 2, in these exhibition light grooves 230 of LGP 200, each exhibition light groove 230 is for example a conical recess, comprises most advanced and sophisticated bottom 231 and one conical wall 232.Conical wall 232 connects most advanced and sophisticated bottom 231 and first surface 210, and intactly around most advanced and sophisticated bottom 231.As shown in Figure 1, if while overlooking the first surface 210 of LGP 200, each exhibition light groove 230 is rounded on first surface 210, and the most advanced and sophisticated bottom 231 of exhibition light groove 230 is centre point.
As shown in Figure 2, because the most advanced and sophisticated bottom 231 1 orthographic projection P of exhibition light groove 230 fall within on light-emitting component 520 by the second perforation 310 and first perforation 430 of correspondence, so exhibition light groove 230 aligning the second perforation 310 and the first perforations 430.
Therefore, as shown in Figure 3, when the light L of light-emitting component 520 arrives at this conical wall 232, the light L of light-emitting component 520 can be reflected into horizontal motion, and it is parallel with first surface 210, finally by the optical microstructures on first surface 210 (pattern), guided, use and become even exiting surface.
Yet the utility model is not limited to this, under the utility model, in technical field, have and conventionally know the knowledgeable, should look the exhibition light groove that other restrictions or elasticity of demand select to adopt other structures.
In addition, the backboard 400 of the utility model thin straight down light source device 100 is not limit its material, kind or form, and backboard 400 for example can be the plate body of plastics, pottery or metal (as aluminium sheet or galvanized steel plain sheet) material.As long as have high light reflectivity, light-reflecting sheet 300 is not limit its material, kind or form, and for example light-reflecting sheet 300 can be light reflection plastic sheet, light reflection graphic patterns or light reverberation and is coated with (plating) layer.Circuit board 510 is not limit its material, kind or form, can be for example printed circuit board (PCB) 510 or flexible circuit board 510.Light-emitting component 520 can be for example light emitting diode.Under the utility model, in technical field, have and conventionally know the knowledgeable, should look backboard, light-reflecting sheet, circuit board and light-emitting component that other restrictions or elasticity of demand select to adopt other materials, kind or form.
As shown in Figure 3, due to the thickness limits of backboard 400 and the limitation in height of light-emitting component 520, light-emitting component 520 can only be luminous from the interior exhibition light groove 230 towards LGP 200 of the first perforation 430, cannot conform to the surface of LGP 200, thereby reduced the laminating degree of these light-emitting components 520 with LGP 200, cannot effectively promote light-emitting component 520 and act on to the luminous efficacy of LGP 200.
Embodiment 2
