[0020] The embodiment of the present application provides a 3D bendable flexible wall washer lamp, which effectively solves the problem that the shell of the lamp is usually made of metal material. This structure makes the lamp have a certain hardness and stability during the installation process. However, at some corners that need to be bent or on curved walls, the lamp with a metal shell cannot be bent, and the lamp will encounter obstacles during the installation process, affecting the installation progress. PU glue layer is used for glue filling production. The PU glue layer is a polyurethane glue, which is an adhesive with excellent properties such as high strength, high elasticity, low temperature resistance, oil resistance, and wear resistance. A flexible substrate material combining a PCB hard board and a PCB soft board, as well as connecting components with certain elasticity and ductility are used, so that the entire PU glue layer and its internal components can be bent without affecting the normal operation of the internal circuits and components. It can be installed along a curved wall, or in some irregularly shaped spaces, its 3D bending ability can adapt to space requirements to provide uniform and soft light.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that the housing of the lamp is usually made of metal material. This structure makes the lamp have a certain hardness and stability during the installation process. However, at some corners that need to be bent or on curved walls, the lamp with a metal housing cannot be bent, and the lamp will encounter obstacles during the installation process, affecting the installation progress. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a flexible wall washer lamp that can be 3D bent, including a PU glue layer 11. At least two PCB flexible boards 15 are fixedly installed inside the PU glue layer 11. At the top end of each PCB flexible board 15, a PCB rigid board 14 is fixedly installed. At the top end of each PCB rigid board 14, a lamp bead 13 is fixedly installed. It is produced by pouring glue into the PU glue layer 11. The PU glue layer 11 is a polyurethane glue, which is an adhesive with excellent properties such as high strength, high elasticity, low temperature resistance, oil resistance, and wear resistance. A flexible substrate material combining the PCB rigid board 14 and the PCB flexible board 15, as well as a connecting component with certain elasticity and ductility, are used, enabling the entire PU glue layer 11 and its internal components to be bent. At the top end of each lamp bead 13, a lens 12 is fixedly installed. A connecting plate 16 is arranged at the top end of the PU glue layer 11. Clamping plates 18 are slidably installed at both side ends of the connecting plate 16.

[0024] A limiting groove 23 is opened at the side end of each clamping plate 18. A telescopic rod 22 is fixedly installed at the side end of each clamping plate 18. Two positioning blocks 19 are fixedly installed on the inner side of each clamping plate 18. A sliding plate 17 is slidably installed at the side end of the connecting plate 16. Two arc-shaped blocks 21 are fixedly installed at the side end of the sliding plate 17. By expanding the distance between the two clamping plates 18 and moving the connecting plate 16, the connecting plate 16 is driven to align the clamping plates 18 with the side ends of the PU glue layer 11. By pressing the top end of the connecting plate 16, the connecting plate 16 is made to fit and align with the top end of the PU glue layer 11. At the same time, the two clamping plates 18 are aligned with the side ends of the PU glue layer 11. Through the reverse acting force of the two telescopic rods 22, the clamping plates 18 drive the positioning blocks 19 to move towards the side ends of the PU glue layer 11. A clamping groove is opened at the side end of the PU glue layer 11, and the positioning blocks 19 are inserted into the inside of the clamping groove. Two clamping grooves are opened at both side ends of the PU glue layer 11.

[0025] Working principle:

[0026] First step: First, weld the rigid PCB 14 and the flexible PCB 15 into a whole. After welding, a lamp bead 13 is installed at the top of the rigid PCB 14, and a lens 12 is also installed at the top of the rigid PCB 14. The lens 12 is used to cover the lamp bead 13. At the same time, both the PU glue layer 11 and the lens 12 are made of transparent materials. After pouring the bottom film in the forming jig, fix the welded rigid PCB 14 and the flexible PCB 15 at the bottom film. The left and right sides of the rigid PCB 14 are folded by the flexible PCB 15 to form a convex shape. Finally, pour the PU glue layer 11 into the potting mold and bond it with the bottom film to form a shape. After the PU glue layer 11 is cooled and formed, fix the internal rigid PCB 14 and the flexible PCB 15. When current passes through the lamp bead 13, the semiconductor material in the lamp bead 13 will generate photons, thus emitting light. The lens 12 can refract and focus the light emitted by the lamp bead 13, so that the light can be emitted at a specific angle and range, thus realizing the effect of wall washing. Moreover, the rigid PCB 14 and the flexible PCB 15 provide circuit connection and support for the lamp bead 13 and its internal electronic components. Through the circuit design on the rigid PCB 14 board, it can ensure that the current is stably and evenly supplied to each lamp bead 13 to ensure its normal light emission.

[0027] Due to the use of the PU glue layer 11 for potting production, the PU glue layer 11 is a polyurethane glue, which is an adhesive with excellent properties such as high strength, high elasticity, low temperature resistance, oil resistance, and wear resistance. The flexible substrate material combining the rigid PCB 14 and the flexible PCB 15 and the connecting components with certain elasticity and ductility are used, so that the entire PU glue layer 11 and its internal components can be bent without affecting the normal operation of the internal circuit and components. It can be installed along the curved wall surface, or in some irregularly shaped spaces, and its 3D bending ability can be used to adapt to the space requirements to provide uniform and soft light.

[0028] Step 2: When in use, butt the twice-formed PU glue layer 11, align and fit the side ends. By expanding the distance between the two clamping plates 18 and moving the connecting plate 16, the connecting plate 16 drives the clamping plates 18 to align with the side ends of the PU glue layer 11. By pressing the top of the connecting plate 16, the connecting plate 16 is aligned and fitted with the top of the PU glue layer 11. At the same time, the two clamping plates 18 are aligned with the side ends of the PU glue layer 11. Through the reverse force of the two telescopic rods 22, the clamping plates 18 drive the positioning blocks 19 to move towards the side ends of the PU glue layer 11. A clamping groove is provided at the side end of the PU glue layer 11, and the positioning blocks 19 are inserted into the inside of the clamping groove. The clamping plates 18 slide mutually at the side ends of the connecting plate 16, and the two clamping plates 18 move towards the inside of the connecting plate 16 to reduce the distance. At the same time, two springs are installed at the side ends of the connecting plate 16. The springs are connected to the sliding plates 17, and the springs apply a pulling force to the sliding plates 17, causing the sliding plates 17 to drive the arc-shaped blocks 21 to slide at the side ends of the connecting plate 16. The sliding plates 17 push the arc-shaped blocks 21 towards the side ends of the clamping plates 18, making the top of the arc-shaped blocks 21 aligned and fitted with the limiting grooves 23 to fix the clamping plates 18. At the same time, the PU glue layer 11 can be quickly assembled and installed by the two clamping plates 18, and the number of installed PU glue layers 11 can be flexibly adjusted according to requirements.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
