Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The wall washer light provided by this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0029] As shown in Figures 1 to 7, an embodiment of this application provides a wall washer light. Optionally, the wall washer light has a long strip structure. Optionally, the wall washer light can be installed on the ceiling or on the wall. When the wall washer light is installed on the wall, it is mounted on a bracket and fixed to the wall by the bracket. The distance between the wall washer light and the wall can be 0.3 to 0.7 m. Of course, it can also be selected according to actual needs. This application embodiment does not impose specific limitations on this.

[0030] The wall washer light includes: a lamp housing 100, a first light source module 200, and a second light source module 300.

[0031] In some embodiments, the first light source module 200 and the second light source module 300 can be controlled independently or centrally, and this application embodiment does not impose specific limitations on this.

[0032] The lamp housing 100 has a first accommodating space and a second accommodating space space that are spaced apart. Optionally, the first accommodating space and the second accommodating space space are arranged side by side along the width direction of the wall washer light. Both the first accommodating space space and the second accommodating space space are stretchable structures and both extend along the length direction of the wall washer light.

[0033] The first receiving space is provided with a first light outlet 110, which is located on the side of the first receiving space away from the ceiling, that is, the first light outlet 110 is located on the side of the lamp housing 100 away from the ceiling, and the first light outlet 110 faces the ground.

[0034] The second receiving space is provided with a second light-emitting port 120, which faces the wall adjacent to the ceiling, that is, the second light-emitting port 120 is opened on the side of the lamp housing 100 facing the wall. Optionally, the opening direction of the second light-emitting port 120 can be perpendicular to the opening direction of the first light-emitting port 110.

[0035] The first light source module 200 is disposed in the first accommodating space, and the second light source module 300 is disposed in the second accommodating space. The first light source module 200 and the second light source module 300 are configured such that the first light emitted by the first light source module 200 and the second light emitted by the second light source module 300 pass through the corresponding first light outlet 110 and the second light outlet 120 and are directed toward the same wall. That is, the first light emitted by the first light source module 200 and the second light emitted by the second light source module 300 pass through the first light outlet 110 and the second light outlet 120 and are directed toward the same wall.

[0036] In this embodiment, since the same wall washer light includes at least two light source modules, the contrasting color wall washer effect can be achieved without additional lighting fixtures installed on the ground, which greatly reduces the installation difficulty of the wall washer light. Furthermore, since the wall washer light of this structure is installed on the ceiling or wall, it avoids the light emitted by the wall washer light being directly in front of the user's eyes, and the wall washer light is farther from the user's eyes, thus avoiding glare and improving the user's visual experience. Therefore, this embodiment can solve the problems of inconvenient installation and glare associated with current wall washer lights. In addition, the second light outlet 120 of the lamp housing 100 faces the wall, which can expand the illumination area of ​​the wall washer light directed towards the wall, thereby improving the light utilization rate of the wall washer light.

[0037] In some embodiments, the first light source module 200 includes a first light source 210 and a first light-transmitting element 220. Optionally, the first light source 210 and the first light-transmitting element 220 may both be disposed on the inner surface of the lamp housing 100, that is, the first light source 210 and the first light-transmitting element 220 are both disposed on the inner surface of the first accommodating space.

[0038] The first light-transmitting element 220 has a first light-incident surface 221 and a first light-exiting surface 222. The first light source 210 is located in the first light-incident cavity formed by the first light-incident surface 221. The first light-exiting surface 222 faces the first light-exiting port 110. The first light emitted by the first light source 210 is first scattered in the first light-incident cavity, then enters the first light-transmitting element 220 from the first light-incident surface 221, and then exits from the first light-exiting surface 222.

[0039] In this embodiment, the first light-transmitting element 220 is used to change the propagation path of the first light within the first accommodating space to optimize the distribution of the first light, thereby improving the light utilization rate of the first light source module 200.

[0040] Of course, the first light-transmitting element 220 mentioned above can also be replaced with a reflective element to reflect the first light ray.

[0041] In some embodiments, the direction in which the first light source module 200 extends toward the second light source module 300 is the first direction, and the first light incident surface 221 is configured to deflect at least a portion of the light incident onto the first light incident surface 221 toward the first direction, that is, the first light transmitting element 220 is a polarizing structure, so that more of the first light emitted by the first light source 210 is directed toward the wall, thereby improving the wall washing effect.

[0042] In a further optional embodiment, the plane where the first light source 210 is located is the first plane, and the first light incident surface 221 includes an inclined surface 221a. Optionally, the inclined surface 221a and the first light source 210 can be arranged opposite to each other so that more of the first light rays are directed toward the inclined surface 221a. The distance between at least a portion of the inclined surface 221a and the first plane gradually decreases along a first direction, that is, the inclined surface 221a can be inclined as a whole along the same direction, or the distance between the inclined surface 221a and the first plane can first gradually decrease and then gradually increase along the first direction, that is, a portion of the inclined surface 221a is inclined along the first direction, and another portion is inclined in the opposite direction. In this case, the inclined surface 221a can be symmetrically arranged about the optical axis of the first light source module 200. Furthermore, optionally, the inclined surface 221a is an arc-shaped convex surface that protrudes toward the direction of the first light source 210. In this case, the area of ​​the inclined surface 221a is larger, which can allow more of the first light rays to be directed toward the wall, thereby further improving the utilization rate of the first light rays and also improving the illumination effect of the first light source module 200. Of course, the inclined surface 221a can also be an inclined plane.

[0043] In other embodiments, the first light-transmitting element 220 also has a first reflective surface 223 and a second reflective surface 224 arranged opposite to each other. In the direction away from the ceiling, the distance between the first reflective surface 223 and the second reflective surface 224 may remain unchanged, or the first reflective surface 223 and the second reflective surface 224 may both be inclined relative to the first plane. In the direction away from the ceiling, the distance between the first reflective surface 223 and the second reflective surface 224 gradually increases, that is, the inclination directions of the first reflective surface 223 and the second reflective surface 224 are opposite. The outer contour line of the cross-section of the first light-transmitting element 220 has a trapezoidal structure. Here, the cross-section specifically refers to the cross-section perpendicular to the length direction of the wall washer light.

[0044] In this embodiment, the first light rays incident on the first light-incident surface 221 propagate in the first light-transmitting element 220. The first light rays located on both sides of the first light-incident cavity are reflected by the first reflective surface 223 and the second reflective surface 224 respectively, so as to change the propagation path of the first light rays and then be emitted from the first light-exiting surface 222. This can not only further improve the utilization rate of the first light rays, but also expand the light spot area of ​​the first light rays illuminating the wall, thereby further improving the illumination effect of the wall washer light.

[0045] In another embodiment, the first reflective surface 223 is disposed close to the second light source module 300, and a first angle is formed between the first reflective surface 223 and the first plane, and a second angle is formed between the second reflective surface 224 and the first plane. The first angle is smaller than the second angle, that is, the tilt of the first reflective surface 223 is smaller than the tilt of the second reflective surface 224, so as to further change the polarization effect of the first light-transmitting element 220, thereby allowing more first light rays to shine onto the wall, and thus improving the utilization rate of the first light rays.

[0046] Optionally, the first light-transmitting element 220 can be a TIR (total internal reflection) lens, which has the characteristics of high light energy utilization, low light loss and good uniformity.

[0047] In some embodiments, the first light-incident surface 221 further includes: a first side surface 221b and a second side surface 221c disposed opposite to each other along a first direction. The second side surface 221c is close to the second light source module 300. An inclined surface 221a connects the first side surface 221b and the second side surface 221c. That is, in the direction perpendicular to the ceiling, the length of the first side surface 221b is less than the length of the second side surface 221c. The first side surface 221b and the second side surface 221c are located on opposite sides of the first light source 210. At this time, one of the first side surface 221b and the second side surface 221c works in cooperation with the first reflective surface 223, and the other works in cooperation with the second reflective surface 224.

[0048] Optionally, both the first side 221b and the second side 221c can be arranged perpendicular to the first plane; or, both the first side 221b and the second side 221c are inclined surfaces, and their inclination directions are opposite. In the direction away from the ceiling, the distance between the first side 221b and the second side 221c gradually decreases, which facilitates the demolding of the first light-transmitting element 220 during the manufacturing process.

[0049] In some embodiments, the tilt angle of the first reflective surface 223 and the tilt angle of the second reflective surface 224 may be the same or different, and the embodiments of this application do not impose specific limitations on this.

[0050] Optionally, the first light-emitting surface 222 can be a plane.

[0051] In another embodiment, the direction in which the first light source module 200 extends toward the second light source module 300 is the first direction. The first light-emitting surface 222 includes a plurality of arc-shaped concave surfaces 222a connected in sequence in the first direction. The arc-shaped concave surfaces 222a can play the role of mixing light and narrowing the beam, so that the first light emitted from the first light-emitting surface 222 can hit the wall as much as possible, thereby improving the utilization rate of the first light.

[0052] Optionally, all of the multiple arc-shaped concave surfaces 222a are stretchable structures, and each arc-shaped concave surface 222a extends along the length direction of the wall washer light.

[0053] In some embodiments, the first light source module 200 further includes a first reflective component 230, which is disposed within a first accommodating space. The first reflective component 230 includes a first reflector 231 and a second reflector 232 spaced apart. The first reflector 231 and the second reflector 232 are arranged spaced apart along the width direction of the first accommodating space. The first light source 210 and the first light-transmitting element 220 are both disposed between the first reflector 231 and the second reflector 232.

[0054] In this embodiment, some stray light in the first light beam passing through the first light-transmitting element 220 is directed towards the first reflector 231 and the second reflector 232. After being reflected by the first reflector 231 and the second reflector 232, it is emitted from the first light outlet 110 to remove stray light in the first light beam directed towards the wall, thereby improving the clarity of the outline of the light spot formed by the first light beam on the wall and thus improving the illumination effect of the first light beam.

[0055] Optionally, the reflective surface of the first reflector 231 and the reflective surface of the second reflector 232 can both be arc-shaped reflective surfaces. The arc-shaped reflective surfaces protrude in a direction away from the first light-transmitting element 220 to increase the reflective area and thereby improve the reflective efficiency of the arc-shaped reflective surfaces.

[0056] In other embodiments, the first light source module 200 further includes: a first circuit board 240, which is disposed on the inner surface of the lamp housing 100, i.e., the first circuit board 240 is disposed in the first accommodating space. The first light source 210 and the first light-transmitting element 220 are both disposed on the first circuit board 240. The first light source 210 and the first light-transmitting element 220 are connected to the inner surface of the lamp housing 100 through the first circuit board 240. The first circuit board 240 is electrically connected to the first light source 210 and is used to supply power to the first light source 210.

[0057] In an optional embodiment, the second light source module 300 includes a second light source 310 and a second light-transmitting element 320. Optionally, the second light source 310 and the second light-transmitting element 320 can both be disposed on the inner surface of the lamp housing 100, that is, the second light source 310 and the second light-transmitting element 320 are both disposed on the inner surface of the second accommodating space. The second light-transmitting element 320 has a second light-incident surface 321 and a second light-exiting surface 322. The second light source 310 is located in the second light-incident cavity formed by the second light-incident surface 321, and the second light-exiting surface 322 faces the second light-exiting port 120. The second light emitted by the second light source 310 is first scattered in the second light-incident cavity, then enters the second light-transmitting element 320 from the second light-incident surface 321, and then exits from the second light-exiting surface 322.

[0058] In this embodiment, the second light-transmitting element 320 is used to change the propagation path of the second light within the second accommodating space to optimize the distribution of the second light, thereby improving the light utilization rate of the second light source module 300.

[0059] Of course, the second light-transmitting element 320 mentioned above can also be replaced with a reflective element to reflect the second light ray.

[0060] In some embodiments, the second light-transmitting element 320 has an arc-shaped structure. In this case, both the second light-incident surface 321 and the second light-exit surface 322 are arc-shaped surfaces, and both the second light-incident surface 321 and the second light-exit surface 322 protrude in a direction away from the second light source 310. The second light emitted by the second light source 310 is first scattered within the second light-incident cavity, then enters the second light-transmitting element 320 from the second light-incident surface 321 for propagation, and then exits from the second light-exit surface 322 and passes through the second light-exit port 120 to reach the wall. In this embodiment, the second light-transmitting element 320 adopts a hyperboloid lens structure to change the propagation path of the second light, thereby allowing more second light to reach the wall and improving the utilization rate of the second light.

[0061] Of course, at least one of the second light-incident surface 321 and the second light-outceasing surface 322 mentioned above can also be a planar structure.

[0062] Optionally, the thickness of the arc-shaped structure can remain unchanged in the circumferential direction; or, in other embodiments, the thickness of the second light-transmitting element 320 gradually increases and then gradually decreases in the circumferential direction of the arc-shaped structure. The area of ​​the second light-emitting surface 322 of the second light-transmitting element 320 in this structure is larger, which is beneficial to the scattering of the second light rays, thereby expanding the area of ​​the light spot on the wall surface illuminated by the second light rays.

[0063] Optionally, in the circumferential direction of the arc-shaped structure, the second light-transmitting element 320 can be symmetrical about the optical axis of the second light source module 300; or, in other optional embodiments, the thickness of the end of the second light-transmitting element 320 near the ceiling is less than the thickness of the end of the second light-transmitting element 320 away from the ceiling, that is, the second light-transmitting element 320 is an asymmetrical structure, so as to achieve a polarizing effect, thereby further increasing the area of ​​the light spot formed by the second light irradiating the wall surface, and thus improving the illumination effect of the second light source module 300.

[0064] In some embodiments, the second light source module 300 further includes a second reflective component 330, which is disposed within the second accommodating space. The second reflective component 330 includes a third reflector 331 and a fourth reflector 332 spaced apart. The third reflector 331 and the fourth reflector 332 are arranged spaced apart along the width direction of the second accommodating space. The second light source 310 and the second light-transmitting element 320 are both disposed between the third reflector 331 and the fourth reflector 332.

[0065] In this embodiment, some stray light in the second light beam passing through the second light-transmitting element 320 is directed towards the third reflector 331 and the fourth reflector 332. After being reflected by the third reflector 331 and the fourth reflector 332, it is emitted from the second light outlet 120 to remove stray light in the second light beam directed towards the wall, thereby improving the clarity of the outline of the light spot formed by the second light beam on the wall and thus improving the illumination effect of the second light beam.

[0066] Optionally, the reflective surfaces of the third reflector 331 and the fourth reflector 332 can both be arc-shaped reflective surfaces. The arc-shaped reflective surfaces protrude in a direction away from the second light-transmitting element 320 to increase the reflective area and thus improve the reflection efficiency.

[0067] In other embodiments, the second light source module 300 further includes: a second circuit board 340, which is disposed on the inner surface of the lamp housing 100. The second light source 310 and the second light-transmitting element 320 are both disposed on the second circuit board 340. The second light source 310 and the second light-transmitting element 320 are connected to the inner surface of the lamp housing 100 through the second circuit board 340. The second circuit board 340 is electrically connected to the second light source 310 and is used to supply power to the second light source 310.

[0068] In some embodiments, the color of the first light beam is different from the color of the second light beam. In this case, when the first light beam and the second light beam illuminate the wall, they can form light spots of different colors, thereby improving the wall washing effect. Of course, the color of the first light beam and the color of the second light beam can also be the same.

[0069] In some embodiments, the power of the first light source 210 and the power of the second light source 310 can be different. In this case, they can emit light with different illumination intensities, that is, the first light and the second light are light with different intensities. When the first light and the second light shine on the wall, they can form light spots of different brightness to improve the wall washing effect. Of course, the power of the first light source 210 and the power of the second light source 310 can also be the same, and there is no specific limitation on this.

[0070] In some other embodiments, a first light beam strikes the wall to form a first light spot, and a second light beam strikes the wall to form a second light spot. The first and second light spots can be spaced apart or connected. Alternatively, the first and second light spots may partially overlap, meaning the first and second light beams striking the wall partially overlap. In this case, the intensity of the overlapping portion is higher, resulting in different lighting effects on the wall. When the colors of the first and second light beams are different, the overlapping portion of the first and second light beams can form a third color (the first light beam is the first color, and the second light beam is the second color), thus achieving contrasting color wall washing, which helps improve the lighting effect of the wall washer light. When the intensities of the first and second light beams are different, the overlapping portion of the first and second light beams can form a medium-intensity light (the first light beam is low-intensity, and the second light beam is high-intensity). In this case, the brightness of the light spot formed by the light emitted by the wall washer light striking the wall is more uniform, which helps improve the wall washing effect of the wall washer light.

[0071] In another alternative embodiment, the lamp housing 100 is configured to be detachably mounted on the ceiling to adjust the distance between the wall washer light and the wall, thereby adjusting the uniformity of illuminance of the light emitted by the wall washer light on the wall. Of course, the lamp housing 100 can also be detachably mounted on the wall, which allows for flexible adjustment of the height of the wall washer light relative to the wall.

[0072] Optionally, in the height direction of the wall, the first light emitted by the first light source module 200 illuminates the wall to form a first light spot. The distance between the lower edge of the first light spot and the ground is 0m, and the distance between the upper edge of the first light spot and the ground is 2.1m. The second light emitted by the second light source module 300 illuminates the wall to form a second light spot. The distance between the lower edge of the second light spot and the ground is 1.2m, and the distance between the upper edge of the second light spot and the ground is 3m. Of course, the distance between the first light spot and the ground and the distance between the second light spot and the ground can be selected according to actual needs. This application embodiment does not impose specific limitations on this.

[0073] Optionally, at least one of the first light-transmitting element 220 and the second light-transmitting element 320 can be a stretched structure that extends along the length of the wall washer light; optionally, at least one of the first light-transmitting element 220 and the second light-transmitting element 320 can be made of optical grade PMMA (Polymethyl Methacrylate, also known as plexiglass or acrylic), or transparent PC (Personal Computer, polycarbonate) or other optical grade transparent materials. This application embodiment does not impose specific limitations on this.
