Description

Technical Field

[0001] This utility model belongs to the field of wall washer light technology, and specifically relates to a novel LED wall washer light structure. Background Technology

[0002] Wall washer lights are a common type of lighting fixture used to outline building contours; also known as linear LED floodlights, they are elongated in shape. Existing wall washer lights typically include a housing, a light source board, a light guide plate, and end plates at both ends. For example, patent CN202123263442.X, entitled "A Novel Wall Washer Light Structure," includes a strip-shaped housing with a light groove. The light groove contains a light source assembly, which includes a circuit board, multiple LEDs mounted on the circuit board, and lenses covering the LEDs, with each lens corresponding to one of the LEDs.

[0003] Although it can meet the general usage needs, the limited shape and structure of the lamp cover cause its wall washing illumination range to be downward direct, resulting in a small wall washing lighting range, affecting the wall washing lighting effect and effectiveness, and limiting its applicability. Utility Model Content

[0004] The purpose of this invention is to provide a novel LED wall washer light structure that has a reasonable structural design and is conducive to improving the illumination range of the wall washer.

[0005] The technical solution to achieve the purpose of this utility model is a novel LED wall washer light structure, including an H-shaped housing and a light source structure fixed to the bottom surface of the horizontal part of the H-shaped housing. The light source structure includes a light source plate, a lens body and a light guide panel.

[0006] The light source plate is fixed to the bottom surface of the transverse part of the H-shaped housing, the lens body is fixed below the light source plate, and the light guide panel is located on the bottom surface of the lens body;

[0007] An inclined light-guiding convex surface is integrally formed at the bottom edge of the light guide panel, and several V-shaped light-guiding convex strips are fixed on the bottom surface of the light guide panel. A reflective surface is provided on the side of the V-shaped light-guiding convex strips away from the inclined light-guiding convex surface.

[0008] After the light from the light source plate passes through the lens, it is reflected by the inclined reflective surface of the V-shaped light guide convex surface and then illuminates from the side close to the inclined light guide convex surface, forming an irradiation area between the inclined light guide convex surface and the inner wall of the H-shaped housing.

[0009] A further preferred embodiment is that the reflective surface is provided with a plurality of parallel arc-shaped reflective protrusions, the arc-shaped reflective protrusions being parallel to the inclined side of the V-shaped light guide strip.

[0010] A further preferred embodiment is that the height of the V-shaped light guide convex strip is less than the height of the inclined light guide convex surface.

[0011] A further preferred embodiment is that the height of one bottom edge of the H-shaped housing is greater than the height of the inclined light-guiding convex surface, and the height of the other bottom edge of the H-shaped housing matches the height of the inclined light-guiding convex surface.

[0012] A further preferred embodiment is that the symmetrical inner wall of the H-shaped shell is provided with positioning grooves;

[0013] Positioning blocks are provided on the symmetrical sides of the lens body;

[0014] The lens body is installed inside the H-shaped housing, and the positioning block is fixed in the positioning slot.

[0015] A further preferred embodiment is that the top of the symmetrical outer wall of the H-shaped shell is provided with a C-shaped groove;

[0016] It is also provided with an n-shaped mounting bracket, wherein the bottom edges of the two vertical parts of the n-shaped mounting bracket are bent inward and have fastening pieces;

[0017] The n-shaped mounting bracket is located on the top surface of the H-shaped housing, and the buckle is positioned by being engaged in the C-shaped groove.

[0018] A further preferred embodiment is that the two ends of the H-shaped housing are fixed with end caps by screws.

[0019] This utility model has positive effects: its structure is reasonably designed, with an inclined light-guiding convex surface integrally formed at the bottom edge of the light guide panel, and several V-shaped light-guiding convex strips fixed on the bottom surface of the light guide panel. The side of the V-shaped light-guiding convex strips away from the inclined light-guiding convex surface is provided with a reflective surface. In use, the light from the light source plate passes through the lens body and is reflected by the inclined reflective surface of the V-shaped light-guiding convex strips before illuminating from the side close to the inclined light-guiding convex surface, forming an illumination area between the inclined light-guiding convex surface and the inner wall of the H-shaped housing. This helps to increase the illumination area. When using wall washing lighting, it can illuminate the wall surface below the side of the lamp, improving the range and effect of wall washing lighting, and enhancing the overall decorative effect of the structure.

The light source structure includes a light source plate 21, a lens body 22, and a light guide panel 23. End caps 6 are fixed to both ends of the H-shaped housing by screws. In this embodiment, the light source plate and lens body are existing structures, simply applied. The thickness of the light guide panel can be set as needed, or it can be integrally formed on the bottom surface of the lens body, mainly for guiding light.

[0030] During installation, the light source plate is fixed to the bottom surface of the transverse portion of the H-shaped housing, the lens body is fixed below the light source plate, and the light guide panel is located on the bottom surface of the lens body. Furthermore, in this embodiment, an inclined light guide convex surface 3 is integrally formed at the bottom edge of the light guide panel, and several V-shaped light guide strips 4 are fixed to the bottom surface of the light guide panel. A reflective surface 5 is provided on the side of the V-shaped light guide strips away from the inclined light guide convex surface. During use, the light from the light source plate passes through the lens body, is reflected by the inclined reflective surface of the V-shaped light guide strips, and then illuminates from the side near the inclined light guide convex surface, forming an illumination area between the inclined light guide convex surface and the inner wall of the H-shaped housing. Guided by the inclined light guide convex surface, the lower edge of the side wall of the H-shaped housing can be illuminated, increasing the illumination area.

[0031] In this embodiment, the reflective surface is provided with a plurality of parallel arc-shaped reflective protrusions, which are parallel to the inclined sides of the V-shaped light guide strip. The arc-shaped reflective protrusions enhance the effectiveness of reflection.

[0032] Furthermore, the height of the V-shaped light guide convex strip is less than the height of the inclined light guide convex surface. The height of one bottom edge of the H-shaped housing is greater than the height of the inclined light guide convex surface, and the height of the other bottom edge of the H-shaped housing matches the height of the inclined light guide convex surface.

[0033] In this embodiment, positioning slots 7 are provided on the symmetrical inner walls of the H-shaped housing; positioning blocks 8 are provided on the symmetrical sides of the lens body; the lens body is installed inside the H-shaped housing, and the positioning blocks are engaged and fixed in the positioning slots.

This ensures ease and effectiveness of installation.

[0035] This utility model has positive effects: its structure is reasonably designed, with an inclined light-guiding convex surface integrally formed at the bottom edge of the light guide panel, and several V-shaped light-guiding convex strips fixed on the bottom surface of the light guide panel. The side of the V-shaped light-guiding convex strips away from the inclined light-guiding convex surface is provided with a reflective surface.

This helps to increase the illumination area. When using wall washing lighting, it can illuminate the wall surface below the side of the lamp, improving the range and effect of wall washing lighting, and enhancing the overall decorative effect of the structure.
