Description

Technical Field

[0001] The utility model relates to the field of lenses, in particular to a wall washer lamp lens. Background Art

[0002] In order to achieve better luminous effect of the product, the selection of optical lens is very important. The lens installed inside the LED wall washer can converge parallel light at one point. By adjusting the angle of the lens, the direction and shape of the light can be controlled.

[0003] The existing Chinese patent publication number is: CN212157035U, which discloses a wall washer lamp lens, including a lens body with a top end surface constituting a light-emitting surface, the middle of the bottom end surface of the lens body is recessed toward the inside of the lens body to form a cavity, the inner wall surface of the cavity constitutes a light-entering surface, the side surface of the lens body constitutes a reflecting surface, and a plurality of straight stripes are arranged on the light-emitting surface, which are closely connected and connected side by side and cover the light-emitting surface. The light-emitting surface is inclined relative to the bottom end surface of the lens body, and the straight stripes are arranged side by side in sequence from the relatively lower side to the relatively higher side of the light-emitting surface. The inclined setting of the light-emitting surface changes the polarization angle of the wall washer lamp lens, so that the area illuminated by the wall washer lamp lens is larger, and the lighting effect on the building is better.

[0004] The existing wall washer lamp lens has the following problems when in use: due to the limitation of the lens, the existing wall washer lamp only illuminates a group of multiple objects when in use, and the effect of illuminating multiple objects with light is not ideal.

[0005] Therefore, it is necessary to invent a wall washer lamp lens to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a wall washer lens to solve the problem in the background art that due to the limitations of the lens, the existing wall washer only illuminates a group of multiple objects when in use, and the effect of illuminating multiple objects is not ideal.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wall washer lamp lens, comprising a lens body, a mounting buckle is fixedly installed on the bottom of the lens body, and the mounting buckle matches the mounting slot reserved inside the light-emitting lamp board, the light-emitting lamp board is embedded and installed inside the lamp housing, and a transparent cover is installed on the top of the lamp housing, a light inlet is reserved at the bottom of the lens body, and a light outlet is provided on the top surface of the lens body.

[0008] Preferably, the two mounting clips form a group, and the two mounting clips are symmetrically arranged with reference to the central axis of the lens body as the axis of symmetry. A group of mounting clips is fixedly installed on the bottom of one of the lens bodies, so that the two mounting clips can be matched with the mounting slots reserved inside the light board, thereby completing the composition of the entire lens body and the light board, ensuring that the lens body is more stable and convenient when in use.

[0009] Preferably, the light inlet is formed by the bottom of the lens body being recessed toward the inside of the lens body, and an arcuate surface is provided on the outer side of the light inlet. After the light enters the light inlet, the arcuate surface shrinks the light to a very small size. The light after shrinkage by the arcuate surface is expanded through the honeycomb structure to form a circular light spot, reaching the vertical wall.

[0010] Preferably, the light emitting surface is an arc structure with a smooth transition from the top to the bottom, and the curvature of the middle part of the arc structure is greater than the curvature of the two sides, which results in a better focusing effect in the middle part of the arc structure. The light on one side passes through the arc structure of the light emitting surface, and the arc structure focuses the light into rectangular light. Because of the curvature of the arc structure, the light can be stretched to eventually form a very long rectangular light spot. Since the focusing effect of the middle part of the arc structure is better, the middle part of the finally formed rectangular light spot is brighter.

[0011] Preferably, the light emitting surface is paved with multiple rows of dense honeycomb structures, and the honeycomb structure is semicircular as a whole. Light is expanded through the honeycomb structure to form a circular light spot, which hits the vertical wall.

[0012] Preferably, the honeycomb structure, the arc-shaped light-emitting surface and the higher end are located in the same horizontal plane.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] The light enters from the light inlet, and the curved surface of the lens body shrinks the light to a very small size. After the light is shrunk by the curved surface, it is expanded through the honeycomb structure to form a circular light spot and reaches the vertical wall. After the light enters the lens body from the light inlet, the other side of the lens body does not act on the light, resulting in the light on this side being divergent light; the light on this side passes through the curved surface structure of the light exiting surface, and the curved surface structure focuses the light into a rectangular light, and because of the curvature of the curved surface structure, the light is elongated to eventually form a very long rectangular light spot, which hits the wall that is perpendicular to the vertical wall (such as objects such as eaves), and the curvature of the middle part of the curved surface structure is greater than the curvature of the two sides, and the focusing effect of the middle part is better, so the middle part of the rectangular light spot finally formed is brighter, and the light has a sense of layering, which makes the illumination effect of the entire wall washer better.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-5 A wall washer lamp lens shown includes a lens body 1, a mounting buckle 5 is fixedly installed on the bottom of the lens body 1, and the mounting buckle 5 matches the mounting slot 6 reserved inside the light-emitting lamp board 2, the light-emitting lamp board 2 is embedded and installed inside the lamp housing 3, and a transparent cover 4 is installed on the top of the lamp housing 3, a light inlet 7 is reserved at the bottom of the lens body 1, and a light outlet surface 9 is provided on the top surface of the lens body 1.

[0025] Two mounting clips 5 form a group, and the two mounting clips 5 are symmetrically arranged with reference to the central axis of the lens body 1 as the symmetry axis. A group of mounting clips 5 is fixedly installed on the bottom of one of the lens bodies 1, so that the two mounting clips 5 can be matched with the mounting slots 6 reserved inside the light board 2, thereby completing the composition of the entire lens body 1 and the light board 2, ensuring that the lens body 1 is more stable and convenient when in use.

[0026] The light inlet 7 is formed by the bottom of the lens body 1 being recessed toward the inside of the lens body 1, and a curved surface 8 is provided on the outer side of the light inlet 7. After the light enters from the light inlet 7, the curved surface 8 shrinks the light to a very small size. The light after shrinkage by the curved surface 8 is expanded through the honeycomb structure 10 to form a circular light spot and reach the vertical wall.

[0027] The light emitting surface 9 is an arc structure with a smooth transition from the top to the bottom, and the curvature of the middle part of the arc structure is greater than the curvature of the two sides, which results in a better focusing effect in the middle part of the arc structure. The light on one side passes through the arc structure of the light emitting surface 9, and the arc structure focuses the light into a rectangular light. Because of the curvature of the arc structure, the light can be stretched to eventually form a very long rectangular light spot. Since the focusing effect of the middle part of the arc structure is better, the middle part of the finally formed rectangular light spot is brighter.

[0028] The surface of the light emitting surface 9 is paved with multiple rows of dense honeycomb structures 10, and the honeycomb structure 10 is semicircular as a whole. The light is expanded through the honeycomb structure 10 to form a circular light spot, which hits the vertical wall.

[0029] The honeycomb structure 10 and the arc-shaped light emitting surface 9 and the higher end are located in the same horizontal plane.

[0030] Working principle: When using a wall washer lens, first match the mounting buckle 5 fixed at the bottom of the lens body 1 with the mounting slot 6 reserved inside the light board 2 to ensure the stability of the lens body 1 installation;

[0031] The light of the light-emitting lamp panel 2 enters the interior of the lens body 1 from the light inlet 7. One side of the lens body 1 is an arc surface 8, which shrinks the light to a very small size. The other side of the lens body 1 does not act on the light, and the light on the other side is divergent light.

[0032] The light rays contracted by the arc surface 8 are expanded by the honeycomb structure 10, so that the light rays form a circular light spot under the action of the honeycomb structure 10, and the circular light spot directly hits the vertical wall;

[0033] The light from the other side of the lens body 1 passes through the arc structure of the light emitting surface 9. The light emitting surface 9 is an arc structure with a smooth transition from the top to the bottom, and the curvature of the middle part of the arc structure is greater than the curvature of the two sides. At this time, the arc structure focuses the light into a rectangular light, and because the curvature of the arc structure can stretch the light, it eventually forms a very long rectangular light spot, which hits an object (such as eaves, etc.) set perpendicular to the vertical wall, and the curvature of the middle part of the arc structure is greater than the curvature of the two sides, and the focusing effect of the middle part is better, so the middle part of the finally formed rectangular light spot is brighter, which makes the light have a sense of layering and shines more in subsequent architectural applications.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
