Benefits of technology

[0015] The beneficial effects of this utility model are as follows: The installation of the light-transmitting plate is ensured by setting a glue groove, using the narrow edge and support part to jointly support and clamp the light-transmitting plate, and then fixing the light-transmitting plate with glue. Furthermore, the top surface of the narrow edge is flush with the top surface of the light-transmitting plate, meaning there is no obstruction to the sides of the light-transmitting plate, effectively increasing the light-emitting area of ​​the wall washer light along its width, thus significantly increasing the light and shadow projection area. The light-transmitting plate and the housing are bonded together with glue, which also enhances the waterproof performance of the wall washer light compared to existing slot installation methods. The end cap abuts against the end side wall of the light-transmitting plate through a thin-walled part, and the top surface of the thin-walled part is flush with the top surface of the light-transmitting plate. The end cap does not obstruct the light-transmitting plate. Because the thickness of the thin-walled part can be made sufficiently thin, when two wall washer lights are spliced ​​end to end, the total thickness of the two thin-walled parts is small, and no obvious shadow is produced at the connection point. Compared to existing technologies, the light-transmitting plate has no obstruction on its outer perimeter, making it less prone to water and dust accumulation, and therefore, the light and shadow effect will not deteriorate due to light refraction and scattering.

Description

Technical Field

[0001] This utility model relates to the field of wall washer light technology. Background Technology

[0002] Wall washer lights are used for architectural and landscape lighting. They are linear in shape and their light shines evenly along the wall, highlighting the texture, lines, or colors of the wall.

[0003] An existing wall washer light structure includes a metal profile housing with a mounting groove along its length inside the housing. A light strip is installed in the mounting groove, and a light-transmitting plate is installed at the opening of the groove. End caps are installed at both ends of the housing. The mounting groove and the end caps each have a slot for mounting the light-transmitting plate. During production, the light-transmitting plate is first inserted into the slot from one end of the housing, and then the end caps are fixed to both ends of the housing. This type of wall washer light has the following problems: 1. The slots on both sides of the mounting groove obstruct the edges of the light-transmitting plate, narrowing the light-emitting surface along the width of the wall washer light and thus reducing the light projection area; 2. The length of a single wall washer light is limited, and multiple wall washer lights need to be connected end to end to form a continuous straight line during installation. However, the slots on the end caps obstruct part of the light-transmitting plate. When two wall washer lights are connected, the obstruction area at the connection point doubles, resulting in a gap in the light projection at the connection point, affecting the decorative effect; 3. Wall washer lights project onto the wall at a certain angle. When projecting from the bottom up, because the light-transmitting plate is installed in the slot, there are obstructions around it that are higher than the light-transmitting plate. This makes it easy for dust to accumulate on the surface of the light-transmitting plate or for rainwater to accumulate on the lower side. This causes light refraction and scattering, resulting in dimming of the lighting, color deviation, and uneven light spots. Therefore, it is necessary to improve this design. Utility Model Content

[0004] The purpose of this invention is to provide a wall washer light with a wider light-emitting surface, no shadows at the connection points, and less accumulating water and dust.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An improved wall washer light structure includes a housing, end caps, a lamp plate, and a light-transmitting plate. The housing is a long, narrow metal profile with a roughly quadrilateral cross-section. An opening along the length of the housing is provided on one side of the quadrilateral, forming a U-shaped mounting groove in the cross-section. The lamp plate is disposed within the mounting groove, and the light-transmitting plate is fitted over the opening of the mounting groove. The end caps include two caps that fit to close both ends of the housing and the light-transmitting plate. Adhesive grooves are formed along the length of the housing on both sides of the mounting groove's opening edge. The cross-section of the adhesive groove covers... The light-transmitting plate includes a narrow edge that abuts against the top of the sidewall corresponding to the light-transmitting plate, a support portion that supports the bottom surface of the light-transmitting plate, and a recess formed between the narrow edge and the support portion, with a gap between the inner surface and the outer surface of the light-transmitting plate. The recess is filled with an adhesive for fixing the light-transmitting plate. The top surface of the narrow edge is flush with the top surface of the light-transmitting plate. Both ends of the light-transmitting plate extend beyond the end face of the housing along the length direction. The top of the end cap has a thin-walled portion that abuts against the end sidewall of the light-transmitting plate. The thickness of the thin-walled portion is less than that of the lower part of the end cap, and the top surface of the thin-walled portion is flush with the top surface of the light-transmitting plate.

[0007] In a preferred embodiment, the gap space of the recess covers part of the sidewall and part of the bottom surface of the light-transmitting plate.

[0008] In a preferred embodiment, the mounting groove is provided with an anti-glare grille, which is arranged parallel to the bottom surface of the light-transmitting plate.

[0009] Furthermore, the inner walls on both sides of the mounting groove have slots for securing the side edges of the grille plate.

[0010] In a preferred embodiment, a sealing gasket is further provided between the end cap and the end face of the housing to seal the end face of the housing.

[0011] Furthermore, the sealing gasket is a U-shaped gasket corresponding to the end face of the housing and arranged around the outer periphery of the mounting groove. The inner wall of the end cap is formed with a receiving groove adapted to the sealing gasket. When the end cap is combined with the end face of the housing, the sealing gasket is not exposed.

[0012] In a preferred embodiment, a fixed bracket is provided on the outer side of the housing away from the light-transmitting plate. The fixed bracket includes a fixing member and a connecting member fixed to the housing. The connecting member and the fixing member are hinged together with an adjustable angle.

[0013] Furthermore, the fixing member includes a fixing plate for fixing to the mounting surface and an adjusting plate perpendicular to the fixing plate, and the connecting member includes a positioning plate that is perpendicular to the housing and extends away from the light-transmitting plate. The adjusting plate is fitted with the positioning plate and locked by a bolt. One of the positioning plate and the adjusting plate is provided with a plurality of positioning holes arranged in an arc around the bolt axis, and the other plate has a positioning protrusion that can cooperate with the positioning holes. By cooperating with different positioning holes, the angle of the housing can be adjusted.

[0014] Furthermore, the fixed bracket includes at least two arranged along the length of the housing; each of the connectors includes two positioning plates arranged in parallel and concentrically, and the positioning plates are provided with corresponding positioning holes.

[0015] The beneficial effects of this utility model are as follows: The installation of the light-transmitting plate is ensured by setting a glue groove, using the narrow edge and support part to jointly support and clamp the light-transmitting plate, and then fixing the light-transmitting plate with glue. Furthermore, the top surface of the narrow edge is flush with the top surface of the light-transmitting plate, meaning there is no obstruction to the sides of the light-transmitting plate, effectively increasing the light-emitting area of ​​the wall washer light along its width, thus significantly increasing the light and shadow projection area. The light-transmitting plate and the housing are bonded together with glue, which also enhances the waterproof performance of the wall washer light compared to existing slot installation methods. The end cap abuts against the end side wall of the light-transmitting plate through a thin-walled part, and the top surface of the thin-walled part is flush with the top surface of the light-transmitting plate. The end cap does not obstruct the light-transmitting plate. Because the thickness of the thin-walled part can be made sufficiently thin, when two wall washer lights are spliced ​​end to end, the total thickness of the two thin-walled parts is small, and no obvious shadow is produced at the connection point. Compared to existing technologies, the light-transmitting plate has no obstruction on its outer perimeter, making it less prone to water and dust accumulation, and therefore, the light and shadow effect will not deteriorate due to light refraction and scattering.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] refer to Figures 1 to 5 This embodiment of an improved wall washer light structure includes a housing 1, end caps 2, a lamp plate 3, and a light-transmitting plate 4. The housing 1 is a long, narrow metal profile with a roughly quadrilateral cross-section. One side of the quadrilateral has an opening along the length of the housing 1, forming a U-shaped mounting groove 11 in the cross-section. The lamp plate 3 is disposed within the mounting groove 11, and the light-transmitting plate 4 is fitted over the opening of the mounting groove 11. The end caps 2 consist of two caps that fit to close both ends of the housing 1 and the light-transmitting plate 4. The end caps 2 are fixed to the end face of the housing 1 by screws or clips. Both sides of the mounting groove 11 have adhesive grooves 12 along the length of the housing 1. The cross-section of the adhesive groove 12 includes a narrow edge 121 that abuts against the top of the corresponding side wall of the light-transmitting plate 4, supporting the... The light-transmitting plate 4 has a support portion 122 on its bottom surface and a recess 123 formed between the narrow edge portion 121 and the support portion 122, with a gap between the inner surface and the outer surface of the light-transmitting plate 4. The recess 123 is filled with an adhesive for fixing the light-transmitting plate 4. The outer side surface 121a of the narrow edge portion 121 is located on the same plane as the side wall of the housing 1, and the top surface 121b of the narrow edge portion 121 is flush with the top surface of the light-transmitting plate 4. The two ends of the light-transmitting plate 4 extend beyond the end face of the housing 1 along the length direction. The top of the end cap 2 has a thin-walled portion 21 that abuts against the end side wall of the light-transmitting plate 4. The thickness of the thin-walled portion 21 is less than that of the lower part of the end cap 2, and the top surface 21a of the thin-walled portion 21 is flush with the top surface of the light-transmitting plate 4.

[0024] A glue groove 12 is provided, and the light-transmitting plate 4 is supported and clamped by the narrow edge 121 and the support part 122. The light-transmitting plate 4 is then fixed by glue, which ensures the reliability of the installation of the light-transmitting plate 4. In addition, the top surface 121b of the narrow edge 121 is flush with the top surface of the light-transmitting plate 4, that is, there is no obstruction on the two sides of the light-transmitting plate 4. Compared with the prior art, for wall washer lights of the same width, this solution can effectively increase the light-emitting area of ​​the wall washer light along the width direction, thereby significantly increasing the light and shadow projection area. The light-transmitting plate 4 is bonded to the housing 1 by glue. Compared with the existing technology of clipping the light-transmitting plate 4, the glue... The body prevents moisture from entering the lamp body through the installation gap, enhancing the waterproof performance of the wall washer light; the end cap 2 abuts against the end side wall of the light-transmitting plate 4 through the thin-walled part 21, and the top surface 21a of the thin-walled part 21 is flush with the top surface of the light-transmitting plate 4. The end cap 2 does not obstruct the light-transmitting plate 4. Since the thickness of the thin-walled part 21 can be made thin enough, when two wall washer lights are spliced ​​end to end, the total thickness of the two thin-walled parts 21 is small, and no obvious shadow will be produced at the connection point; compared with the existing technology, the light-transmitting plate 4 has no edge on the outer perimeter, making it less prone to water and dust accumulation, and therefore the light and shadow effect will not be deteriorated due to light refraction and scattering.

[0025] As a preferred embodiment, the gap space of the recess 123 in this embodiment covers part of the sidewall and part of the bottom surface of the light-transmitting plate 4, that is, the colloid and the light-transmitting plate 4 are bonded together with an L-shaped contact surface. This increases the bonding area and bonding strength between the colloid and the light-transmitting plate 4, making the installation of the light-transmitting plate 4 more reliable, while not obstructing the light path.

[0026] As a preferred embodiment, the mounting groove 11 in this embodiment is provided with an anti-glare grille 5, which is arranged parallel to the bottom surface of the light-transmitting plate 4. Furthermore, the inner walls on both sides of the mounting groove 11 have slots 13 for securing the side edges of the grille 5. The grille 5 is mainly used to control the light emission angle and prevent glare. By confining the grille 5 within the slots 13, compared to the existing method of clamping it between the LED and the light-transmitting plate 4, the grille 5 is less prone to displacement, thus ensuring that the projection angle and area remain unchanged.

[0027] As a preferred embodiment, a sealing gasket 6 is further provided between the end cap 2 and the end face of the housing 1 to seal the end face of the housing 1. Further, the sealing gasket 6 is a U-shaped gasket corresponding to the end face of the housing 1 and surrounding the outer periphery of the mounting groove 11. The inner wall of the end cap 2 is formed with a receiving groove 22 adapted to the sealing gasket 6. When the end cap 2 is engaged with the end face of the housing 1, the sealing gasket 6 is not exposed. The sealing gasket 6 can seal the end of the housing 1, preventing water from entering the wall washer light; while the U-shaped gasket is hidden inside the receiving groove 22, preventing it from contacting moisture and dust and rapidly aging and failing.

[0028] As a preferred embodiment, a fixing bracket 7 is provided on the side of the housing 1 away from the light-transmitting plate 4. The fixing bracket 7 includes a fixing member 71 and a connecting member 72 fixed to the housing 1. The connecting member 72 and the fixing member 71 are hinged together with an adjustable angle. The fixing bracket 7 is used to install the wall washer light and adjust the overall illumination angle of the wall washer light.

[0029] Furthermore, the fixing member 71 includes a fixing plate 711 for fixing to the mounting surface, and an adjusting plate 712 perpendicular to the fixing plate 711. The connecting member 72 includes a positioning plate 721 perpendicular to the housing 1 and extending away from the light-transmitting plate 4. The adjusting plate 712 is fitted to the positioning plate 721 and locked by a bolt 722. One of the positioning plate 721 and the adjusting plate 712 has a plurality of positioning holes 723 arranged in an arc around the axis of the bolt 722, while the other plate has a positioning protrusion 713 that can cooperate with the positioning holes 723. By cooperating with different positioning holes 723, the angle of the housing 1 can be adjusted. When adjusting the angle, first loosen the bolt 722 to separate the positioning plate 721 from the adjusting plate 712, thereby disengaging the positioning protrusion 713 from the positioning hole 723 and changing its position, and then tighten the bolt 722 again.

[0030] Furthermore, the fixed bracket 7 includes at least two arranged along the length of the housing 1; each connector 72 includes two parallel and concentrically arranged positioning plates 721, and the two positioning plates 721 are correspondingly provided with positioning holes 723. Since the wall washer light has multiple fixed brackets 7, and the positioning plates 721 are arranged in corresponding pairs, any positioning plate 721 can be combined with the adjustment plate 712 for angle adjustment, improving the convenience of installation.

[0031] The above description does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
