[0002] Existing high-power wall washer lights on the market are mostly long, rectangular aluminum shells that are not flexible and cannot conform to the contours of buildings. On walls with complex contours, they need to be cut into multiple sections and then spliced ​​together to form the required curvature, which cannot fit the wall well. Therefore, a high-power, flexible, and arbitrarily bendable wall washer light needs to be designed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a high-power, flexible, arbitrarily bendable wall washer light to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-power, flexible, bendable wall washer light includes a housing, which is a closed hollow silicone tube. The hollow silicone tube has a closed cavity formed by a light-emitting surface and two light-shielding surfaces. The wall washer light includes several basic unit modules, each of which is connected by an FPC connecting plate. Each basic unit module includes a high-power LED, a driver IC, a lens, an aluminum substrate PCB, and a finned heat sink. The basic unit modules are arranged linearly and equidistantly. The high-power LED, aluminum substrate PCB, and driver IC are assembled using SMT technology to complete the individual light emission. The electrical connection of the light unit is as follows: PCB connection points are reserved around the high-power LED. The FPC connection board completes the electrical connection of multiple light-emitting units through the reserved PCB connection points. Screw holes are opened on the fin heat sink. The pressure plate is locked to the reserved screw holes of the bottom fin heat sink by screws. A hole is opened in the middle of the pressure plate. A lens is installed on the pressure plate through the hole. The silicone sleeve has a reserved groove inside. The bottom fins of the fin heat sink enter the silicone sleeve through the reserved groove. A large aluminum heat sink is installed on the back of the aluminum substrate PCB. The aluminum substrate PCB and the fin heat sink are connected by screws.

[0006] As a further embodiment of this invention: the light-emitting surface is composed of transparent silicone, and the light-shielding surface is composed of opaque colored silicone.

[0007] As a further embodiment of this invention, each of the basic unit modules is connected by a steel wire rope.

[0008] As a further embodiment of this utility model: a wire locking device is provided between the finned heat sinks. The wire locking device is a cylindrical structure with a hole in the middle to facilitate the threading of a steel wire rope and threads at both ends to lock the steel wire rope.

[0009] As a further embodiment of this utility model: a recessed fastener is provided on both sides of the silicone lamp body for easy installation.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The outer shell of the wall washer light is composed of a closed silicone hollow sleeve. The transparent silicone light-emitting surface and the silicone light-shielding surfaces on both sides and bottom form a closed cavity. The transparent silicone light-emitting surface is composed of transparent silicone, which facilitates the transmission of light emitted from the internal lens. The silicone light-shielding surface is composed of opaque colored silicone, which prevents excess light from escaping. The end caps on both sides are glued to the lamp body to form a completely sealed whole, which achieves waterproof and moisture-proof effects. The basic unit modules are arranged at equal intervals in a linear manner and distributed in the silicone hollow sleeve. The modules are connected by FPC connecting plates to ensure complete electrical connection between each module. The flexible connecting wire is in a U-shape between the two modules. This shape allows for sufficient extension space when the lamp is bent. Furthermore, it allows for slight bending within a limited lateral range; high-power LEDs, aluminum substrate PCBs, and driver IC components are electrically connected to a single light-emitting unit using SMT technology. This light-emitting unit, with its bottom coated with thermally conductive adhesive, forms a tight connection with the finned heat sink, significantly enhancing its heat dissipation capability; the lens is positioned by passing through the central hole of the pressure plate, and the gap between the two contact surfaces is filled with adhesive, increasing the contact area far more than simply applying adhesive to the contact surface between the lens and the aluminum substrate PCB, resulting in a much higher connection strength. Each module is reinforced with steel wire rope connections to ensure that the FPC connection board will not break when subjected to external impacts. The addition of finned heat sinks significantly improves... The high heat dissipation performance of the lamp provides convenient conditions for high-power design. At the same time, the fin design increases the contact area with air, thereby increasing the heat dissipation area. A layer of high thermal conductivity adhesive is applied between the back of the aluminum substrate PCB and the heat sink, which can improve the heat dissipation of the lamp and increase the connection between the aluminum substrate PCB and the fin heat sink, further improving the structural stability of the product. The lamp body is made of soft silicone material, which is easy to bend. The wall washer uses an aluminum substrate + FPC flexible board connection + heat sink combination to achieve good flexibility and heat dissipation. The wall washer is assembled in a modular manner, which is easy to bend in multiple directions. The internal modules are connected by steel wire ropes, which can achieve stronger tensile strength.

The high-power LED 10, the aluminum substrate PCB 7, and the driver IC are manufactured using SMT technology to achieve single-unit light emission. The electrical connection of the unit is as follows: PCB connection points 12 are reserved around the high-power LED 10. The FPC connection board 13 completes the electrical connection of multiple light-emitting units through the reserved PCB connection points 12. Screw holes 11 are opened on the fin heat sink 8.

The aluminum substrate PCB 7 and the fin heat sink 8 are connected by screws 11.

[0019] In this embodiment, the outer shell of the wall washer light is composed of a closed silicone hollow sleeve. The transparent silicone light-emitting surface 1 and the silicone light-shielding surfaces 3 on both sides and bottom form a closed cavity. The transparent silicone light-emitting surface 1 is made of transparent silicone, which allows light emitted from the internal lens 5 to pass through. The silicone light-shielding surface 3 is made of opaque colored silicone, which prevents excess light from escaping. The end caps 9 on both sides are glued to the lamp body to form a completely sealed whole, which achieves waterproof and moisture-proof effect. The basic unit modules are arranged at equal intervals in a linear manner and distributed in the silicone hollow sleeve. The modules are connected by an FPC connecting plate 13 to ensure complete electrical connection between each module. The flexible connecting wire is in a U-shape between the two modules.

Furthermore, it bends slightly within a limited lateral range; the high-power LED10, aluminum substrate PCB7, and driver IC components are electrically connected to a single light-emitting unit via SMT technology. This light-emitting unit, through the application of thermally conductive adhesive to its bottom, forms a tight connection with the finned heat sink 8, greatly enhancing its heat dissipation capability; the lens 5 is positioned by the central hole of the pressure plate 6, and adhesive is filled into the gap between the two contact surfaces, compared to only connecting the lens 5 and the aluminum substrate PCB7...

Each module is reinforced with steel wire rope 15 to ensure that the FPC connecting plate 13 will not break when subjected to external impact. The addition of finned heat sink 8 can significantly improve the heat dissipation performance of the lamp and provide convenient conditions for high-power design. At the same time, the finned design increases the contact area with air and increases the heat dissipation area. A layer of high thermal conductivity adhesive is applied between the back of the aluminum substrate PCB7 and the heat sink, which can improve the heat dissipation of the lamp and increase the connection between the aluminum substrate PCB7 and the finned heat sink 8, further improving the structural stability of the product.

The wire locking device 14 is a cylindrical structure with a hole in the middle to facilitate the threading of the steel wire rope 15 and threads at both ends to lock the steel wire rope 15.

[0021] In this embodiment, after the wire locking device 14 is placed in place, the steel wire rope 15 is inserted through the hole in the middle of the wire locking device 14 and then sequentially inserted into all subsequent basic unit modules. The steel wire rope 15 is then locked with screws 11 to prevent it from slipping. At the same time, the distance between each basic unit module is positioned to ensure that the FPC connecting plate 13 maintains a U-shaped structure at the connection position of each basic unit module.

[0022] As an embodiment of this utility model, a recessed fastener is reserved on both sides of the silicone lamp body to facilitate installation.

The basic unit modules are arranged at equal intervals in a linear manner and distributed in the silicone hollow sleeve. The modules are connected by an FPC connecting plate 13 to ensure complete electrical connection between each module. The flexible connecting line is in a U-shape between the two modules. This shape can provide sufficient space for extension when the lamp is bent. Furthermore, it bends slightly within a limited lateral range; the high-power LED10, aluminum substrate PCB7, and driver IC components are electrically connected to a single light-emitting unit via SMT technology.
