Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wall washer light technology, and specifically relates to a flexible wall washer light. Background Technology
[0002] Wall washer lights, as common linear lighting devices in architectural lighting projects, are mainly used to outline the contours of building facades and enhance their three-dimensional visual appeal, playing a crucial role, especially in nighttime landscape lighting. Most existing wall washer lights utilize aluminum profile structures, achieving uniform light projection by encapsulating the light source, lens, and other components within a rigid lamp body. This type of structure offers advantages in strength, heat dissipation, and standardized assembly, thus being widely used in linear lighting scenarios on various building walls.
[0003] However, with the diversification of modern architectural design styles, more and more building facades are exhibiting irregular contours such as curved surfaces, folded surfaces, arc surfaces, and even free-form shapes. Traditional aluminum profile wall washer lights, due to their rigid structure and inflexibility, cannot conform to the curved surfaces of buildings for installation, often requiring custom-made light body structures for different buildings. This not only increases production costs and extends delivery cycles but also increases construction complexity and labor costs. Furthermore, when facing complex installation scenarios such as facade corners and curved walls, rigid light bodies struggle to guarantee a proper fit, easily leading to problems such as blind spots, inconsistent splicing, and insecure installation, severely impacting the overall lighting effect and aesthetic uniformity.
[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content
[0005] In view of the technical problems mentioned in the background art, the purpose of this utility model is to provide a flexible wall washer light to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexible wall washer light, comprising a mounting body, an internal mounting groove, a light-emitting slot on one side of the mounting groove, an illumination surface embedded in the light-emitting slot, a light source circuit board installed inside the mounting groove, the mounting body being made of silicone strip material, the light source circuit board being a flexible circuit board, and the illumination surface being made of a flexible transparent material.
[0007] Furthermore, the lamp body is integrally formed using an extrusion molding process.
[0008] Furthermore, the light source circuit board has light-emitting beads uniformly arranged on one end of the surface facing the illumination surface, and a focusing lens is respectively covered on the outer side of several of the light-emitting beads.
[0009] Furthermore, the lower two sides of the lighting surface are symmetrically provided with reinforcing protrusions, and the two reinforcing protrusions are respectively provided on the inner sides of the mounting groove. The lighting surface and the light-emitting slot are bonded and fixed together by adhesive.
[0010] Furthermore, the inner sides of the mounting groove are symmetrically provided with circuit board mounting positions, and the light source circuit board is set on the two circuit board mounting positions and fixed by adhesive.
[0011] Furthermore, the bottom of the focusing lens is provided with a connecting protrusion ring, which is bonded and fixed to the surface of the light source circuit board by adhesive.
[0012] The present invention has the following advantages: the interior of the lamp body is recessed with a mounting groove, and a light-emitting slot is opened on one side of the mounting groove. An illumination surface is embedded in the light-emitting slot. A light source circuit board is installed inside the mounting groove. The lamp body is made of silicone strip material and is integrally formed by extrusion molding, which has good flexibility, bendability and weather resistance. The light source circuit board is a flexible circuit board, which can deform synchronously with the bending deformation of the lamp body, ensuring the continuity and reliability of electrical connection. The illumination surface is made of flexible transparent material, which not only has good light transmission performance, but also can maintain a tight fit when the lamp body deforms. The flexible wall washer light of the present invention is easy to install and highly adaptable, and can effectively adapt to the diverse curved surfaces or irregular contours of building exterior walls, improving installation efficiency and lighting aesthetics.

Detailed Implementation
[0018] like Figures 1 to 4As shown, a flexible wall washer light includes a mounting body 10, with a mounting groove 11 recessed inside the mounting body 10. A light-emitting slot 12 is formed on one side of the mounting groove 11, and an illumination surface 20 is embedded in the light-emitting slot 12. A light source circuit board 30 is installed inside the mounting groove 11. Light-emitting LED beads 31 are uniformly arranged on the surface of the end of the light source circuit board 30 facing the illumination surface 20. A condensing lens 32 is respectively covered on the outer side of several LED beads 31. In use, the light emitted by several LED beads 31 is converged by the condensing lens 32 and then emitted along the direction of the illumination surface 20, realizing directional illumination of the wall. The light distribution is uniform and the projection distance is long, improving the clarity and brightness of the wall washer effect.
[0019] In practice, the mounting body 10 is made of silicone strip material and integrally molded using an extrusion molding process. This process gives the mounting body 10 good flexibility, ensuring that it is not easily broken or delaminated during long-term bending and installation. It can conform to the curvature of the building wall for a close fit, which not only improves the convenience of construction, but also broadens the application range of wall washer lights in complex scenarios such as irregular buildings, facade corners, and curved surfaces.
[0020] In practical implementation, the light source circuit board 30 is a flexible circuit board with good bendability and fatigue resistance. When external force causes the lamp body 10 to deform, the light source circuit board 30 can bend and fold synchronously with the lamp body without affecting the electrical performance, ensuring the normal operation of the light-emitting LED 31. With the deformable characteristics of the light source circuit board 30, the entire flexible wall washer light can freely deform to conform to the complex contours of buildings (such as hubs, curved surfaces, and irregular facades), adapting to various installation needs and avoiding installation obstacles or blind spots caused by rigid structures.
[0021] In practical implementation, the lighting surface 20 is made of a flexible transparent material, preferably flexible silicone or thermoplastic polyurethane (TPU). This material has good optical transmittance, flexibility and weather resistance, and can be bent and deformed with the lamp body 10 without affecting the light output effect, so as to meet the lighting needs of various non-linear walls or irregular building contours.
[0022] In practical implementation, the lower two sides of the lighting surface 20 are symmetrically provided with reinforcing protrusions 21. These two reinforcing protrusions 21 are respectively located on the inner sides of the mounting groove 11 to enhance the structural connection strength between the lighting surface 20 and the mounting lamp body 10, preventing the lighting surface 20 from detaching or shifting under repeated bending or external force. Simultaneously, the lighting surface 20 and the light-emitting slot 12 are bonded together using adhesive, preferably weather-resistant transparent silicone or acrylic adhesive for sealing and bonding. This not only ensures installation firmness but also provides a certain degree of waterproof and dustproof performance.
[0023] In specific implementation, the inner sides of the mounting groove 11 are symmetrically provided with circuit board mounting positions 111. The light source circuit board 30 is set on the two circuit board mounting positions 111 and is fixed by adhesive. It is preferred to use flexible electronic special adhesive with good adhesion and high temperature resistance, such as thermally conductive silicone or epoxy resin adhesive for bonding.
[0024] In practical implementation, the bottom of the focusing lens 32 is provided with a connecting protrusion 321. The connecting protrusion 321 is bonded and fixed to the surface of the light source circuit board 30 by adhesive. It is preferable to use transparent light-guiding or high-temperature resistant adhesives (such as UV-curing adhesives or silicone) for dispensing to ensure a firm and reliable connection. Through the above structural design, the focusing lens 32 can be stably covered on the outside of the corresponding light-emitting lamp bead 31, realizing concentrated light emission and directional control, thereby improving the uniformity of the lighting effect and the illumination distance, which is suitable for occasions that require precise wall washing effects.
[0025] In summary, the interior of the lamp body 10 is recessed with a mounting groove 11, and a light-emitting slot 12 is formed on one side of the mounting groove 11. An illumination surface 20 is embedded in the light-emitting slot 12. A light source circuit board 30 is installed inside the mounting groove 11. The lamp body 10 is made of silicone strip material and is integrally formed by extrusion molding, possessing good flexibility, bendability, and weather resistance. The light source circuit board 30 is a flexible circuit board that can deform synchronously with the bending deformation of the lamp body, ensuring the continuity and reliability of electrical connections. The illumination surface 20 is made of flexible transparent material, which not only has good light transmission performance but also maintains a tight fit when the lamp body deforms. The flexible wall washer light of this utility model is easy to install, highly adaptable, and can effectively adapt to the diverse curved surfaces or irregular contours of building exterior walls, improving installation efficiency and lighting aesthetics.
