[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] Combination Figure 1 As shown, the embodiment of the present disclosure provides a reflective assembly for a lighting device, comprising: a reflective sheet 100 and a reflective strip 200. There are one or more reflective strips 200, and when there are multiple reflective strips 200, each reflective strip 200 is connected to the side of the reflective sheet 100; wherein each reflective strip 200 and the reflective sheet 100 are an integrated structure.

[0041] With the reflective assembly for lighting devices provided by the embodiment of the present disclosure, since each reflective strip 200 and the reflective sheet 100 are of an integrated structure, the gap between the reflective strip 200 and the reflective sheet 100 is reduced, thereby reducing the effect of the gap on light reflection and improving the lighting effect. In addition, there is no need to attach the reflective strip 200 separately, which reduces the attachment error and improves the assembly efficiency.

[0042] Optionally, the reflective sheet 100 is rectangular, so that the reflective sheet 100 has a regular shape, is relatively simple to produce, and is convenient for the reflective strip 200 to be connected thereto.

[0043] It is understandable that, due to the different shapes of the light board 300 , the reflective sheet 100 may also be in other shapes, such as a circle, a triangle, or other irregular shapes, so that the reflective sheet 100 is better adapted to the light board 300 .

[0044] Optionally, the reflective sheet 100 is made of PET (Polyethylene terephthalate, polyester resin) material, and a reflective layer is provided on the reflective surface of the reflective sheet 100. In this way, the reflective sheet 100 made of PET material has a relatively low production cost and good folding resistance, thereby reducing the risk of the reflective sheet 100 being broken due to bending when attached to the light board 300.

[0045] It can be understood that the reflective surface of the reflective sheet 100 is a side surface facing away from the light board 300 .

[0046] Optionally, the reflective strip 200 is made of PET (Polyethylene terephthalate, polyester resin) material, and a reflective layer is provided on the reflective surface of the reflective strip 200. In this way, the reflective strip 200 made of PET material has a relatively low production cost and good folding resistance, thereby reducing the risk of the reflective strip 200 being broken due to bending during the paving process.

[0047] It can be understood that the reflective surface of the reflective strip 200 is a side surface connected to the reflective surface of the reflective sheet 100 .

[0048] Combination Figure 2 As shown, optionally, a plurality of lamp holes 110 are provided on the reflective sheet 100. Thus, when the reflective sheet 100 is attached to the lamp board 300, since a plurality of lamp beads 310 are provided on the lamp board 300, the lamp beads 310 can pass through the lamp holes 110, thereby reducing the shielding of the light of the lamp beads 310.

[0049] Specifically, 25 lamp holes 110 are provided on the reflective sheet 100 .

[0050] Combination Figure 3As shown, optionally, a positioning hole 120 is provided on the reflective sheet 100. Thus, by providing the positioning hole 120, the reflective sheet 100 can be better attached to the light board 300, thereby improving the attachment accuracy.

[0051] Optionally, a plurality of positioning holes 120 are provided. Thus, by providing a plurality of positioning holes 120 , the precision of attaching the reflective sheet 100 to the light board 300 is further improved.

[0052] Specifically, two positioning holes 120 are provided.

[0053] Optionally, the reflective sheet 100 and the reflective strip 200 are connected by a plurality of connecting strips, and the plurality of connecting strips are arranged at intervals. In this way, since the reflective sheet 100 and the reflective strip 200 have a certain angle after paving, the reflective sheet 100 and the reflective strip 200 need to be bent so that the angle between the reflective sheet 100 and the reflective strip 200 meets the requirements of paving, and the connecting strips arranged at intervals are easier to bend, and the required bending force is smaller. In addition, the connecting strips arranged at intervals can also provide bending instructions for operators, reducing the risk of bending errors.

[0054] Optionally, the reflective sheet 100, the reflective strip 200 and the connecting strip are an integrated structure. In this way, the gaps between the reflective strip 200, the reflective sheet 100 and the connecting strip are relatively small, which reduces the effect of the gaps on light reflection and improves the lighting effect.

[0055] Optionally, the material of the connecting strip is the same as that of the reflective sheet 100 and the reflective strip 200. In this way, the material of the connecting strip corresponds to that of the reflective sheet 100 and the reflective strip 200. When the reflective sheet 100 and the reflective strip 200 are connected by the connecting strip, the strength of the connection is relatively high, reducing the risk of the connecting strip breaking during the bending process.

[0056] Combination Figure 4-1 , Figure 4-2 and Figure 5 As shown, optionally, in the case where two reflective strips 200 are provided, one reflective strip 200 is connected to one side of the reflective sheet 100, and the other reflective strip 200 is connected to an adjacent side or an opposite side of the reflective sheet 100. In this way, in the case where one reflective strip 200 is connected to one side of the reflective sheet 100, and the other reflective strip 200 is connected to an adjacent side of the reflective sheet 100, the remaining two side edges of the reflective sheet 100 are convenient to be spliced ​​with the other reflective strips 200, so as to cooperate with the splicing of the light board 300. In the case where one reflective strip 200 is connected to one side of the reflective sheet 100, and the other reflective strip 200 is connected to an opposite side of the reflective sheet 100, the two opposite side edges of the reflective sheet 100 where no reflective strip 200 is provided are convenient to be spliced ​​with the other reflective strips 200, so as to cooperate with the splicing of the light board 300.

[0057] In one embodiment, when two reflective strips 200 are provided, one reflective strip 200 is connected to one side of the reflective sheet 100, and the other reflective strip 200 is connected to an adjacent side of the reflective sheet 100, the two reflective sheets 100 are independently connected to the reflective sheet 100. In this way, the two reflective strips 200 are independently connected to the reflective sheet 100, and the angles between the reflective sheet 100 and the two reflective strips 200 can be set to be different, and the bending angle is more flexible.

[0058] Combination Figure 4-2 As shown, in another embodiment, when two reflective strips 200 are provided, one reflective strip 200 is connected to one side of the reflective sheet 100, and the other reflective strip 200 is connected to an adjacent side of the reflective sheet 100, the two reflective strips 200 are an integrated structure. In this way, the two reflective strips 200 are an integrated structure, which reduces the gap between the two reflective strips 200, reduces the influence of the gap on light reflection, and improves the lighting effect.

[0059] In one embodiment, when three reflective bars 200 are provided and the three reflective bars 200 are connected to three adjacent sides of the reflective sheet 100, the three reflective bars 200 are integrally formed. In this way, the three reflective bars 200 are an integral structure, which reduces the gaps between the three reflective bars 200, reduces the effect of the gaps on light reflection, and improves the lighting effect.

[0060] In another embodiment, when three reflective strips 200 are provided and the three reflective strips 200 are connected to three adjacent sides of the reflective sheet 100, the three reflective strips 200 are independently connected to the reflective sheet 100. In this way, the three reflective strips 200 are independently connected to the reflective sheet 100, and the angles between the reflective sheet 100 and the three reflective strips 200 can be set to be different, and the bending angle is more flexible.

[0061] It is understandable that, when each side of the reflective sheet 100 is connected to a corresponding reflective strip 200 , each reflective strip 200 can be independently connected to the reflective sheet 100 in an integral manner, and adjacent reflective strips 200 can also be connected to the reflective sheet 100 and connected to each other in an integral manner.

[0062] Combination Figure 6 As shown, in some embodiments, a lighting device includes the reflective assembly for the lighting device of the above embodiment.

[0063] The lighting device provided by this embodiment includes the reflective assembly for lighting device of the above embodiment, and each reflective strip 200 and reflective sheet 100 are of an integrated structure, so the gap between the reflective strip 200 and the reflective sheet 100 is reduced, thereby reducing the effect of the gap on light reflection and improving the lighting effect. In addition, there is no need to attach the reflective strip 200 separately, which reduces the attachment error and improves the assembly efficiency.

[0064] Optionally, the lighting device further includes: a lamp board 300. A plurality of lamp beads 310 are disposed on one side wall of the lamp board 300; wherein the reflective sheet 100 is disposed on the side wall of the lamp board 300 on which the lamp beads 310 are disposed. In this way, the lamp holes 110 on the reflective sheet 100 correspond to each other, the reflective sheet 100 is attached to the lamp board 300, and the lamp beads 310 can pass through the lamp holes 110, thereby reducing the obstruction of the light of the lamp beads 310.

[0065] Specifically, 25 lamp beads 310 are arranged on one side wall of the lamp board 300. In this way, the 25 lamp beads 310 correspond to the 25 lamp holes 110 on the reflector 100. The reflector 100 is attached to the lamp board 300, and the lamp beads 310 can pass through the lamp holes 110, reducing the shielding of the light of the lamp beads 310.

[0066] Specifically, the reflective sheet 100 is attached to a side wall of the light board 300 provided with the lamp beads 310. In this way, part of the light emitted by the lamp beads 310 is irradiated on the reflective sheet 100 and the reflective strip 200, and then the reflective sheet 100 and the reflective strip 200 cooperate to reflect the light and improve the lighting effect.

[0067] Optionally, a plurality of light panels 300 are provided, and the light panels 300 can be spliced. In this way, the light panels 300 can be spliced, and a plurality of light panels 300 can form spliced ​​light panels 300 of different areas, thereby meeting different area requirements, and when one of the light panels 300 is damaged, the damaged light panel 300 can be replaced, and the maintenance cost is relatively low.

[0068] Optionally, the light board 300 is a rectangular plate structure. In this way, the shape of the reflector 100 corresponds to the shape of the light board 300, so that the reflector 100 is better attached to the light board 300. In addition, the shape of the light board 300 is relatively regular, and the production is relatively simple, which also makes it easier to splice the light boards 300 with each other.

[0069] Combination Figure 7As shown, optionally, when there are multiple light panels 300, adjacent light panels 300 are spliced ​​together by splicing pieces 400. In this way, by splicing adjacent light panels 300 by splicing pieces 400, multiple light panels 300 can form spliced ​​light panels 300 of different areas, thereby meeting different area requirements, and when one of the light panels 300 is damaged, the damaged light panel 300 can be replaced, and the maintenance cost is relatively low.

[0070] Optionally, the splicing piece 400 includes: a splicing rod 410 and a splicing hole 420. The side wall of the light panel 300 is provided with a splicing hole 420; one end of the splicing rod 410 is plugged into the splicing hole 420 on the side wall of one light panel 300, and the other end of the splicing rod 410 is plugged into the splicing hole 420 on the side wall of another light panel 300. In this way, the light panels 300 are spliced ​​together by plugging the splicing rod 410 into the splicing hole 420, and the stability of the connection is relatively high. A plurality of light panels 300 can form spliced ​​light panels 300 of different areas to meet different area requirements, and when one of the light panels 300 is damaged, the damaged light panel 300 can be replaced, and the maintenance cost is relatively low.

[0071] Optionally, each side wall of the lamp panel 300 is provided with a plurality of splicing holes 420. Thus, by providing a plurality of splicing holes 420, each splicing hole 420 is plugged with a corresponding splicing rod 410, so that the lamp panels 300 are spliced ​​together, further improving the stability of the connection.

[0072] Specifically, two splicing holes 420 are provided on each side wall of the lamp panel 300. Thus, by providing two splicing holes 420, each splicing hole 420 is plugged with a corresponding splicing rod 410, so that the lamp panels 300 are spliced ​​together, and the stability of the connection is further improved.

[0073] Optionally, when multiple light panels 300 are spliced ​​together, each light panel 300 is provided with a corresponding reflective sheet 100, and the sides of each reflective sheet 100 adjacent to the other reflective sheets 100 are adjacent sides, and the sides other than the adjacent sides of each reflective sheet 100 are provided with reflective strips 200. In this way, after the light panels 300 are spliced, if each side of the adjacent reflective sheets 100 is provided with reflective strips 200, the reflective sheets 100 will overlap and interfere, affecting the reflection effect of light. Therefore, the sides other than the adjacent sides of each reflective sheet 100 are provided with reflective strips 200, thereby reducing the risk of overlap and interference of the reflective sheets 100 and improving the reflection effect of light.

[0074] Exemplarily, when two light boards 300 are provided, the two light boards 300 are spliced ​​together, and the two reflective sheets 100 are adjacent. A side of the reflective sheet 100 adjacent to another reflective sheet 100 has no reflective strip 200, and the other sides of the reflective sheet 100 are all provided with reflective strips 200.

[0075] For example, when there are four light boards 300, the four light boards 300 are spliced ​​together, and each light board 300 is adjacent to two light boards 300. Four reflective sheets 100 are provided corresponding to the four light boards 300, and each reflective sheet 100 has two sides adjacent to other reflective sheets 100, and the remaining two sides except the two adjacent sides are provided with reflective strips 200. And the two sides of each reflective sheet 100 provided with the reflective strips 200 are adjacent.

[0076] Exemplarily, when there are four light boards 300, the four light boards 300 are spliced ​​together, and the four light boards 300 are arranged in sequence in one direction and arranged in a long strip shape. The two opposite sides of the two light boards 300 in the middle are adjacent to the other light boards 300; the two light boards 300 at the two ends have one side adjacent to the other light boards 300. Then, the reflective sheets 100 on the two light boards 300 in the middle, each reflective sheet 100 is only provided with two reflective strips 200, which are arranged on the two opposite sides of the reflective sheet 100, and the remaining two sides of the reflective sheet are adjacent sides. The reflective sheets 100 on the two light boards 300 at the two ends, each reflective sheet 100 is provided with three reflective strips 200, and the three reflective strips 200 are connected to the three sides of the reflective sheet 100, and the remaining one side is an adjacent side.

[0077] Optionally, a positioning rod 320 is provided on the light board 300. In this way, the positioning rod 320 is matched with the positioning hole 120 on the reflector 100, so that the reflector 100 can be better attached to the light board 300, improving the attachment accuracy and reducing the attachment difficulty.

[0078] Optionally, there are multiple positioning rods 320. In this way, in coordination with multiple positioning holes 120, each positioning rod 320 corresponds to one positioning hole 120, so that the reflector 100 can be better attached to the light board 300, the attachment accuracy is improved, and the attachment difficulty is reduced.

[0079] Specifically, two positioning rods 320 are provided. In this way, in cooperation with the two positioning holes 120, each positioning rod 320 corresponds to one positioning hole 120, so that the reflector 100 can be better attached to the light board 300, the attachment accuracy is improved, and the attachment difficulty is reduced.

[0080] Combination Figure 8As shown, optionally, the lighting device further includes: a back plate 500. A mounting groove is provided on one side wall of the back plate 500, the lamp board 300 is arranged in the mounting groove, and the reflective strip 200 is partially attached to the back plate 500. In this way, the lamp board 300 is installed in the mounting groove, the reflective sheet 100 is attached to the lamp board 300, and the reflective strip 200 is attached to the gap between the lamp board 300 and the back plate 500, and the reflective sheet 100 and the reflective strip 200 reflect light to improve the lighting effect.
