Abstract
Description
Technical Field
[0001] This utility model relates to lighting fixtures, and more particularly to a wall washer light. Background Technology
[0002] Wall washer lights are commonly used for architectural lighting and beautifying the surrounding environment. Some existing wall washer lights consist of a base and a light-emitting component. The base includes a bottom shell and a light-emitting cover, which together form a cavity. The light-emitting component is located within this cavity. The light-emitting cover has a light-emitting aperture. The light-emitting component includes a light-emitting element and a lens. When a wall washer light is in use, the light emitted by the light-emitting element can be refracted by the lens and then emitted directly or refracted through the light-emitting aperture. Areas not illuminated by the light will form dark areas. Currently, the dark areas in wall washer lights are relatively large, and the lighting effect is still somewhat insufficient.

[0031] Reference Figures 1 to 5 The present invention relates to a base 100 and a light-emitting component 200. The base 100 includes a bottom shell 110 and a light-emitting cover 120. The light-emitting cover 120 and the bottom shell 110 enclose a receiving cavity 101. The light-emitting cover 120 is provided with a light-emitting hole 121, which communicates with the receiving cavity 101. One end of the light-emitting hole 121 near the receiving cavity 101 forms a light inlet 122, and the other end of the light-emitting hole 121 away from the receiving cavity 101 forms a light outlet 123. The light-emitting component 200 is disposed on the base 100 and located within the receiving cavity 101. The light-emitting component 200 includes a light-emitting body 210 and a lens element 220. The light-emitting body 210 and the lens element 220 are opposite to each other, and the light-emitting side of the light-emitting component 200 faces the light inlet 122. The light-emitting cover 120 has a notch 124 on a portion of the periphery of the light outlet 123.
[0032] When the wall washer light is installed and used, the notch 124 of the light outlet 121 is relatively close to the wall to be illuminated. The light emitted by the light source 210 is refracted by the lens 220 and enters the light outlet 121 from the light inlet 122. Then it is emitted from the light outlet 123 of the light outlet 121 to illuminate the wall of the building. Because the notch 124 is set at part of the periphery of the light outlet 123, some light can be emitted from the notch 124, thereby diffusing the illumination range, that is, reducing the height of the dark area of the wall washer light and improving its lighting effect.
[0033] In the embodiments, reference is made to Figure 3The light-emitting aperture 121 has a rectangular cross-section perpendicular to its axis. A first aperture sidewall 1211, a second aperture sidewall 1212, a third aperture sidewall 1213, and a fourth aperture sidewall 1214 are arranged sequentially around the aperture axis. A notch 124 is located at the end of the first aperture sidewall 1211 near the light-emitting aperture 123. A clearance slope 1215 is formed at the end of the first aperture sidewall 1211 near the notch 124. Typically, one side of a wall washer light is closest to the wall. By making the cross-section of the light-emitting aperture 121 rectangular, the first aperture sidewall 1211 is closest to the wall. The clearance slope 1215 at the first aperture sidewall 1211 forms the notch 124. Part of the light from the light-emitting aperture 121 can pass through the notch 124 and illuminate the wall, thereby reducing the height of the dark area of the wall washer light and eliminating the need for notches 124 on all aperture sidewalls, thus improving light utilization and reducing glare.
[0034] In the embodiments, reference is made to Figure 1 and Figure 2 It also includes a dark area adjustment block 300, which is detachably mounted on the light emitter cover 120 and located at the notch 124. In some cases, wall washer lights require a larger dark area, hence the dark area adjustment block 300. When the wall washer light requires a smaller dark area height, the dark area adjustment block 300 can be removed, allowing light to shine through the notch 124 onto the wall. When the wall washer light requires a larger dark area height, the dark area adjustment block 300 can be installed. In this case, the dark area adjustment block 300 can block the notch 124, preventing light from the light emitter 121 from escaping through the notch 124, thereby increasing the dark area height.
[0035] In the embodiments, reference is made to Figure 2 The dark area adjustment block 300 is magnetically mounted on the light emitter cover 120. One end of the dark area adjustment block 300 abuts against the side wall 1212 of the second hole, and the other end abuts against the side wall 1214 of the fourth hole. This magnetic mounting method allows the dark area adjustment block 300 to be detachably mounted on the light emitter cover 120, resulting in a simple structure and relatively convenient installation.
[0036] Specifically, a magnet can be provided in the dark area adjustment block 300 and an iron part can be provided in the light output mask 120; or an iron part can be provided in the dark area adjustment block 300 and a magnet can be provided in the light output mask 120, so that the dark area adjustment block 300 can be magnetically installed.
[0037] It is conceivable that in other embodiments, the dark area adjustment block 300 may also be detachably mounted to the light emitter 120 by other means, such as by snap-fit or screw connection, etc., at the notch 124 position of the light emitter 120.
[0038] In the embodiments, reference is made to Figure 3 Both the second hole sidewall 1212 and the fourth hole sidewall 1214 are inclined relative to the axis of the light-emitting hole 121. Along the direction from the light inlet 122 to the light outlet 123, the distance between the second hole sidewall 1212 and the fourth hole sidewall 1214 gradually increases. The inclination of both the second hole sidewall 1212 and the fourth hole sidewall 1214 allows for a larger light-emitting width from the light-emitting hole 121. Since the two ends of the dark area adjustment block 300 abut against the second hole sidewall 1212 and the fourth hole sidewall 1214 respectively, the distance between them gradually increases along the direction from the light inlet 122 to the light outlet 123. This means that the second hole sidewall 1212 and the fourth hole sidewall 1214 can abut against and position the dark area adjustment block 300, eliminating the need for an additional positioning structure to use with magnetic attraction for positioning. The structure is simple and the performance is good.
[0039] In this embodiment, the first hole sidewall 1211 forms an anti-glare surface, while the second hole sidewall 1212, third hole sidewall 1213, and fourth hole sidewall 1214 form reflective surfaces. Since the first hole sidewall 1211 is relatively close to the wall, when a user observes the building cavity wall illuminated by the wall washer light at a relatively close distance, some light can easily be reflected into the user's eyes through the first hole sidewall 1211, causing glare. Therefore, setting the first hole sidewall 1211 as an anti-glare surface can reduce the risk of light reflecting into the user's eyes through the first hole sidewall 1211, i.e., reduce glare.
[0040] Specifically, the first hole sidewall 1211 is made of black material to reduce its reflectivity and glare. The second hole sidewall 1212, the third hole sidewall 1213, and the fourth hole sidewall 1214 can be made of metal or coated with reflective paint to give them good reflectivity and increase the intensity of light reflected onto the wall.
[0041] In this embodiment, the lens 220 is a polarizing lens, which allows more light emitted from the light source 210 to reach the wall surface, thereby improving the brightness and illumination effect of the wall surface.
[0042] In the embodiments, reference is made to Figure 1 and Figure 2 The base 100 is strip-shaped, and the light-emitting cover 120 has six light-emitting holes 121 arranged along the length of the base 100. Six light-emitting components 200 are also arranged along the length of the base 100, with each light-emitting component 200 corresponding to one of the light-emitting holes 121. The strip-shaped base 100, with its plurality of light-emitting holes 121 and six light-emitting components 200, can illuminate a relatively long area, providing good lighting effects. The structure is simple and easy to implement.
[0043] It is conceivable that in other embodiments, the base 100 may also be provided with two, three or more light-emitting holes 121, and the light-emitting component 200 may also be provided with two, three or more correspondingly, without limitation here.
[0044] In the embodiments, reference is made to Figure 4 and Figure 5 It also includes a mounting bracket 400, which is slidably connected to the base 100 along its length. The base 100 can be mounted on the ground or wall via the mounting bracket 400. The mounting bracket 400 can slide along the length of the base 100, allowing its position to be flexibly adjusted to facilitate the installation of the wall washer light in a predetermined position.
[0045] In the embodiments, reference is made to Figure 5 The base 100 has an end that can be spliced with the end of another base 100 along its length. The base 100 has a connector strip 111 along its length, and the mounting bracket 400 has a connector groove 401. The connector strip 111 slides into the connector groove 401. The mounting bracket 400 can extend beyond the current base 100 relative to its length and engage with another base 100. When two wall washer lights are spliced along their length, the ends of the two bases 100 are joined together, and the mounting bracket 400 can be moved between the two bases 100, allowing it to be simultaneously inserted into both bases 100. This enhances the splicing strength of both bases and allows for simultaneous installation and fixation of both wall washer lights, resulting in better installation stability and greater flexibility in use.
[0046] Specifically, the bottom shell 110 is provided with a sliding groove 112 along its length, and both sides of the sliding groove 112 are provided with plug-in strips 111. The mounting bracket 400 has two plug-in slots 401, and the plug-in strips 111 are located in the plug-in slots 401 in a one-to-one correspondence.
[0047] Specifically, the mounting bracket 400 includes a plate 410 and two elastic arms 420. One end of each elastic arm 420 is connected to the plate 410, and a insertion groove 401 is formed between the elastic arm 420 and the mounting plate. The two elastic arms 420 are located within the sliding groove 112. In the aforementioned mounting bracket 400, the elastic arms 420 can elastically deform, allowing the mounting bracket 400 to be elastically snapped into the sliding groove 112, while simultaneously allowing the insertion strip 111 to snap into the insertion groove 401; or it can detach from the insertion strip 111 through elastic deformation. The mounting bracket 400 is relatively easy to install and disassemble.
[0048] Specifically, the mounting bracket 400 is a one-piece molded sheet metal part, which allows its elastic arm 420 to be elastic.
[0049] It is conceivable that in other embodiments, the mounting bracket 400 may also be movable along the length of the base 100 through other structures, for example, the mounting bracket 400 may be movably connected to the base 100 through a guide post and guide sleeve structure.
[0050] Specifically, the light-emitting element 210 is an LED chip, and the light-emitting component 200 also includes a lamp board 230, on which all LED chips are mounted.
[0051] Specifically, the base 100 also includes an intermediate plate 130, which is fixedly installed on the bottom shell 110 and located in the accommodating cavity 101. The light emitter 120 is installed on the intermediate plate 130 by snap-fit. The light emitter 120 and the light-emitting component 200 are respectively placed on opposite sides of the intermediate plate 130.
[0052] It is conceivable that in other embodiments, the light source 210 may also be other structures with light-emitting functions, such as LED beads.
[0053] Specifically, the bottom shell 110 is detachably connected to end caps 140 at both ends. After the end caps 140 are removed, the base 100 can be spliced along the length direction.
