In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] Please also read Figure 1 and Figure 2 , the lighting device provided by the embodiment of the present application is now described. The lighting device comprises a flexible light board 2, a light-transmitting film 1, a back film 3 and a wiring board 4. The flexible light board 2 has a light-emitting surface 20 and a back surface 21 opposite to each other. The light-transmitting film 1 is stacked on the light-emitting surface 20. The back film 3 is stacked on the back surface 21, the edge of the back film 3 is pressed against the edge of the light-transmitting film 1, and a mounting hole 30 is provided at one end of the back film 3. The wiring board 4 is arranged between the light-transmitting film 1 and the back film 3, and the wiring board 4 is exposed from the back film 3 through the mounting hole 30, and the flexible light board 2 is electrically connected to the wiring board 4.

[0043] The "flexibility" mentioned in the article refers to the ability of the material to change its shape after being subjected to force, that is, to bend and deform.

[0044] A flexible light board 2 is used as a light-emitting component, and a light-transmitting film 1 is covered on the light-emitting surface 20 of the flexible light board 2 to ensure that the light emitted by the flexible light board 2 can be emitted through the light-transmitting film 1 to achieve the lighting function. A back film 3 is covered on the back side 21 of the flexible light board 2, and the back film 3 is pressed against the edge of the light-transmitting film 1 to install the flexible light board 2 and the wiring board 4 inside and form a whole. A mounting hole 30 is provided on the back film 3 to expose the wiring board 4 so that the wiring board 4 can be connected to an external controller or power supply.

[0045] Compared with the prior art, the lighting device provided by the present application is made of flexible materials as a whole, can be bent when in use, and is thin and light as a whole, easy to carry and transport, and not easy to break. In addition, the light-transmitting film 1 and the back film 3 are pressed and fixed together to achieve the overall sealing of the lighting device, achieving a waterproof effect.

[0046] It can be understood that the area size of the light-transmitting film 1 and the back film 3 should be larger than that of the flexible light board 2, at least one circle larger than the flexible light board 2, so as to ensure that the light-transmitting film 1 and the back film 3 can be internally sealed after being pressed together.

[0047] In another embodiment of the present application, the light-transmitting film 1 is a transparent TPU film layer.

[0048] The transparent TPU film layer is light, thin, flexible and wear-resistant. The transparent TPU film layer also has high light transmittance and good waterproof performance.

[0049] In another embodiment of the present application, the back film 3 is a TPU film layer, specifically a nylon coated TPU film.

[0050] Nylon coated TPU membrane has excellent waterproof breathability and flexibility.

[0051] In another embodiment of the present application, please continue to refer to Figure 1 and Figure 2 A first fixing layer 5 is provided between the light-transmitting film 1 and the flexible light board 2 , and the first fixing layer 5 is used to fix the light-transmitting film 1 and the flexible light board 2 .

[0052] The flexible light board 2 is fixed to the light-transmitting film 1 by the first fixing layer 5 , so that the flexible light board 2 can be prevented from shifting and the structural stability can be ensured.

[0053] Of course, the first fixing layer 5 disposed between the light-transmitting film 1 and the flexible light board 2 needs to achieve a fixing function while not blocking the light of the flexible light board 2 .

[0054] Therefore, in another embodiment of the present application, please refer to Figures 1 to 3 The flexible light board 2 includes a flexible substrate 22 and a plurality of light strips 23. The plurality of light strips 23 are arranged on the flexible substrate 22 at intervals, and the flexible substrate 22 is electrically connected to the wiring board 4. The first fixing layer 5 is a solid adhesive layer, and a through groove 50 is provided on the solid adhesive layer. The solid adhesive layer exposes the light strips 23 through the through groove 50.

[0055] The light bar 23 is the light source of the flexible light board 2, and the flexible substrate 22 is used as the mounting base of the light bar 23, and the light bar 23 is electrically connected to the wiring board 4 through the flexible substrate 22. The light bar 23 is regularly arranged on the flexible substrate 22, and the solid glue layer is provided with a through groove 50 at the position corresponding to the light bar 23, and the lamp beads are exposed through the through groove 50, so as to ensure that the solid glue layer does not cover the light bar 23 and ensure the lighting effect.

[0056] Therefore, in practice, the solid adhesive layer is used to bond and fix the flexible substrate 22 and the light-transmitting film 1 .

[0057] In another embodiment of the present application, the solid adhesive layer is a foam adhesive layer.

[0058] Using a foam adhesive layer as the solid adhesive layer can, on the one hand, achieve a good bonding and fixing effect; on the other hand, the foam adhesive is elastic and soft, and can achieve a shock-absorbing and buffering effect on the flexible light panel 2 .

[0059] The solid adhesive layer can be specifically formed by sticking a plurality of solid adhesive layers respectively on the positions of the flexible substrate 22 away from the light bar 23 and connecting them to form a whole surface.

[0060] The thickness of the solid glue layer should be at least greater than the height of the lamp beads to ensure that both sides of the solid glue layer can fully contact the light-transmitting film 1 and the flexible substrate 22 respectively.

[0061] In another embodiment of the present application, the flexible substrate 22 is a flexible printed circuit board (FPC for short).

[0062] Flexible circuit boards are flexible, thin and bendable.

[0063] In another embodiment of the present application, please continue to refer to Figure 1 and Figure 2 A white frame 6 is provided between the light-transmitting film 1 and the flexible light panel 2 , and the white frame 6 is arranged around the light-transmitting film 1 at 360 degrees.

[0064] The white frame 6 is arranged between the light-transmitting film 1 and the flexible light board 2, that is, the white frame 6 is located on the light-emitting surface 20 of the flexible light board 2. The white frame 6 can reflect the light without blocking the light emitted by the flexible light board 2, thereby achieving the effect of improving the brightness. Furthermore, the white frame 6 can also cover the edge of the lighting equipment and the wiring, playing the role of hiding the ugliness.

[0065] In another embodiment of the present application, the white frame 6 is a white TPU frame. The frame made of TPU material has excellent softness.

[0066] Specifically, the white frame 6 is specifically arranged between the light-transmitting film 1 and the first fixing layer 5 (solid adhesive layer). Since the light-transmitting film 1 and the white frame 6 are both made of TPU material, the two can be fixed and sealed by heat pressing. The first fixing layer 5 is bonded at the position corresponding to the white frame 6. Therefore, the position corresponding to the light-transmitting film 1 in the middle of the first fixing layer 5 is bonded to the light-transmitting film 1, and the position corresponding to the edge of the first fixing layer 5 and the white frame 6 is bonded to the white frame 6.

[0067] In another embodiment of the present application, please continue to refer to Figure 1 and Figure 2 A second fixing layer 7 is provided between the flexible light board 2 and the back film 3 , and the second fixing layer 7 is used to fix the flexible light board 2 and the back film 3 .

[0068] The flexible light board 2 and the back film 3 are fixed by the second fixing layer 7, so as to avoid displacement of the flexible light board 2 and ensure structural stability.

[0069] In another embodiment of the present application, the second fixing layer 7 is a thermal conductive adhesive layer.

[0070] The thermally conductive adhesive layer can not only fix the flexible light board 2 and the back film 3, but also dissipate heat for the flexible light board 2, dissipate the heat generated by the flexible light board 2 more quickly, and ensure the performance of the lighting equipment.

[0071] In another embodiment of the present application, please continue to refer to Figure 1 and Figure 2 The wiring board 4 is arranged at one end of the flexible light board 2 , and a copper foil piece 8 is arranged between the wiring board 4 and the flexible light board 2 .

[0072] The wiring board 4 is connected to an external controller via an external electrical connection line so as to control the light bar 23 to emit light, adjust the light brightness or light color of the light bar 23, etc.

[0073] A copper foil piece 8 is arranged between the terminal board 4 and the flexible lamp board 2. The copper foil has good thermal conductivity, which can further improve the heat dissipation effect of the flexible lamp board 2 and the connecting board. In addition, the copper foil also has good electrical conductivity, and the grounding function is achieved through the copper foil to ensure the safety performance of the lighting equipment.

[0074] Specifically, the copper foil 8 is attached to the aluminum plate 9, and the aluminum plate 9 is stacked between the flexible light board 2 and the back film 3. The aluminum plate 9, as a carrier of the copper foil 8, can play a good heat dissipation performance.

[0075] It should be noted that in order to ensure the bendability of the lighting device, the thickness of the aluminum plate 9 is controlled to be less than 2 mm. The aluminum plate 9 with a thickness of less than 2 mm has a certain degree of bendability. Therefore, when the aluminum plate 9 is used as a carrier of the copper foil 8, the lighting device as a whole can be slightly bent, which not only plays a good heat dissipation performance, but also gives the lighting device itself a certain support strength.

[0076] Furthermore, the thickness of the aluminum plate 9 may be 0.5 mm, 1 mm, or 1.5 mm, and the thickness of the aluminum plate 9 may also be any value between the above adjacent values.

[0077] In this embodiment, the thickness of the aluminum plate 9 is 1 mm.

[0078] Based on the case where an aluminum plate 9 is provided between the flexible light board 2 and the back film 3, the number of the second fixing layer 7 (thermal conductive adhesive layer) is two layers, one of which is provided between the aluminum plate 9 and the flexible light board 2 to achieve the bonding and fixation of the aluminum plate 9 and the flexible light board 2, and the other is provided between the aluminum plate 9 and the back film 3 to achieve the bonding and fixation between the aluminum plate 9 and the back film 3.

[0079] In another embodiment of the present application, please refer to Figure 2 and Figure 3 The wiring board 4 includes an FPC cable 40 , a mounting shell 41 , a plurality of FPC boards 43 and a plurality of fixing shells 42 .

[0080] The FPC cable 40 is a connecting wire group that can be bent within a certain degree. The FPC cable 40 is used to connect the flexible light board 2 (flexible substrate 22) and multiple FPC boards 43, so that the multiple FPC boards 43 can adjust and control the light bar 23.

[0081] The mounting shell 41 is fixed on the back film 3 , and one side of the mounting shell 41 passes through the mounting hole 30 on the back film 3 and goes out of the back film 3 . The FPC cable 40 is fixed on the side of the back film 3 away from the flexible light board 2 by double-sided adhesive.

[0082] A plurality of FPC boards 43 are arranged and installed in the mounting shell 41. The mounting shell 41 is provided with a through slot, and the FPC cable 40 extends into the mounting shell 41 through the through slot and is connected to the plurality of FPC boards 43.

[0083] The number of the fixing shells 42 corresponds to the number of the FPC boards 43. The fixing shell 42 is provided with fasteners, and the flexible light board 2, the aluminum plate 9 and the copper foil piece 8 are all provided with through holes for the fasteners to pass through. The fasteners of the fixing shell 42 pass through the through holes of the flexible light board 2, the aluminum plate 9 and the copper foil piece 8 in sequence and are connected to the mounting shell 41 to achieve fastening.

[0084] In another embodiment of the present application, please refer to Figure 2 A Velcro 10 is provided on the side of the back film 3 facing away from the flexible light board 2 .

[0085] By providing the Velcro 10, it is easy to disassemble and assemble the lighting device and the external structure, thereby improving the convenience of use. In addition, the Velcro 10 is used for fixing, which can ensure that the overall bendability of the lighting device is not affected, and the Velcro 10 is thin and light and can be reused many times.

[0086] Specifically, the Velcro 10 is arranged around the back film 3 at 360 degrees to fix the lighting device on all sides.

[0087] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
