[0022] Compared with the prior art, the technical solution of the present utility model has the following beneficial effects:

[0023] In the wall washer lamp provided by the technical solution of the present utility model, since in each lighting module, the second slope is less than the first slope in the first lighting unit and the second lighting unit, therefore, the light emitted by the first light source module and the light emitted by the second lighting unit can be controlled respectively. The light of the first lighting unit is deflected more to the upper half area of the wall surface, and the light of the second lighting unit is deflected more to the lower half area of the wall surface, so that a plurality of lighting modules arranged along the first direction form two lighting areas with different heights (i.e., the first lighting area and the second lighting area). Thus, a relatively high upper part light spot and a relatively low lower part light spot can be formed on the wall surface. At the same time, since the color and / or color temperature of the light emitted by the second light source module is different from that of the light emitted by the first light source module, therefore, the color and / or color temperature of the light of the upper part light spot and the lower part light spot are different. Thus, lights with different colors and different color temperatures can be illuminated on the wall surface simultaneously with a simple structure. Moreover, by adjusting the first slope, the second slope, the curvature of the first reflecting surface and the curvature of the second reflecting surface, the lower part area of the first lighting area and the upper part area of the second lighting area can be partially overlapped. Thus, the lower half area of the upper part light spot and the upper half area of the lower part light spot can overlap with each other. Furthermore, the color and / or color temperature of the light illuminated on the wall surface are increased, and lights with multiple different colors and different color temperatures can be illuminated on the wall surface simultaneously, rendering a better wall washing effect. Especially in the case of different colors, a better lighting color collision effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] To make the objectives, features, and beneficial effects of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0040] It should be understood that the described embodiments are only partial embodiments of the present utility model, rather than all embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope protected by the present utility model.

[0041] An embodiment of the present utility model provides a wall washer light. It is set that the length direction of the wall washer light is the first direction X, the depth direction of the wall washer light is the second direction Y, and the height direction of the wall washer light is the third direction Z.

[0042] Preferably, the wall washer light is suitable for being installed on the ceiling.

[0043] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0044] Figure 1 It is a three-dimensional structural schematic diagram of a wall washer light according to an embodiment of the present utility model. Figures 2 to 3is a semi-sectional schematic view of a lighting module according to an embodiment of the present utility model, Figure 4 is a schematic optical path diagram according to an embodiment of the present utility model, Figure 5 is a partial bottom view of a wall washer according to an embodiment of the present utility model, Figure 6 is a schematic light effect diagram of a wall washer according to an embodiment of the present utility model. Among them, Figure 4 the light rays in are represented by dotted lines with arrows.

[0045] Please refer to Figures 1 to 6 , the wall washer includes: a plurality of lighting modules 10, the plurality of lighting modules 10 are arranged along a first direction X, and the lighting module 10 has opposite first side 11 and second side 12.

[0046] Among them, the first side 11 is adapted to be adjacent to the wall surface.

[0047] The lighting module 10 includes: a first lighting unit 100 and a second lighting unit 200 arranged adjacent to each other.

[0048] The light emitted by the first lighting units 100 of the plurality of lighting modules 10 forms a first lighting area I, and the light emitted by the second lighting units 200 of the plurality of lighting modules 10 forms a second lighting area II. Moreover, at least part of the first lighting area I is higher than the second lighting area II, so as to form light spots in different areas of the wall surface through the first lighting units 100 and the second lighting units 200 of the plurality of lighting modules 10 respectively. Specifically, the light spot formed by the first lighting unit 100 on the wall surface is above, and the light spot formed by the second lighting unit 200 on the wall surface is below.

[0049] Preferably, at least part of the lower region of the first lighting area I and the upper region of the second lighting area II overlap, so that an overlapping light spot area is also formed on the wall surface.

[0050] The first lighting unit 100 is provided with: a first light source module 110 and a first reflecting surface 1211.

[0051] The first light source module 110 is located in the top region of the first reflecting surface 1211, the first reflecting surface 1211 faces the first side 11, and the first reflecting surface 1211 is an arc surface recessed away from the first side 11.

[0052] The second lighting unit 200 is provided with: a second light source module 210 and a second reflecting surface 2211.

[0053] The second light source module 210 is located in the top region of the second reflecting surface 2211, the second reflecting surface 2211 faces the first side 11, and the second reflecting surface 2211 is an arc surface recessed away from the first side 11.

[0054] Among them, the color and / or color temperature of the light emitted by the second light source module 210 is different from that of the light emitted by the first light source module 110, and the second slope is less than the first slope.

[0055] Among them, the first slope refers to the slope of the connection line L1 between the two ends of the arc projection of the first reflecting surface 1211 on the depth plane (as Figure 3 shown), and the second slope refers to the slope of the connection line L2 between the two ends of the arc projection of the second reflecting surface 2211 on the depth plane (as Figure 3 shown).

[0056] Among them, the depth plane is a plane formed along the height direction and the depth direction of the wall washer light.

[0057] Since in each lighting module 10, the first lighting unit 100 and the second lighting unit 200, the second slope is less than the first slope, therefore, the light emitted by the first light source module 110 and the light emitted by the second lighting unit 200 can be respectively controlled for light deflection. More light from the first lighting unit 100 is deflected to the upper half area of the wall surface, and more light from the second lighting unit 200 is deflected to the lower half area of the wall surface, so that multiple lighting modules 10 arranged along the first direction X form two lighting areas with different heights (i.e., the first lighting area I and the second lighting area II). Thus, a relatively high upper part light spot and a relatively low lower part light spot can be formed on the wall surface. At the same time, since the color and / or color temperature of the light emitted by the second light source module 210 is different from that of the light emitted by the first light source module 110, therefore, the color and / or color temperature of the light of the upper part light spot and the lower part light spot are different. Thus, lights of different colors and different color temperatures can be simultaneously illuminated on the wall surface with a simple structure.

[0058] Moreover, by adjusting the first slope, the second slope, the curvature of the first reflecting surface 1211 and the curvature of the second reflecting surface 2211, the lower part area of the first lighting area I and the upper part area of the second lighting area II can also be partially overlapped. Thus, the lower half area of the upper part light spot and the upper half area of the lower part light spot can overlap. Furthermore, the color and / or color temperature of the light illuminated on the wall surface is increased, and lights of multiple different colors and different color temperatures can be simultaneously illuminated on the wall surface, rendering a better wall washing effect. Especially in the case of different colors, a better light color collision effect is achieved.

[0059] Furthermore, the first light source module 110 and the second light source module 210 are located at the same height.

[0060] Further, the first light source module 110 includes a plurality of first light sources 111, the second light source module 210 includes a plurality of second light sources 211, and the distance between the first light source 111 and the first reflecting surface 1211 in the second direction Y is less than the distance between the second light source 211 and the second reflecting surface 2211 in the second direction Y.

[0061] That is to say, compared with the second light source 211 and the second reflecting surface 2211, the first light source 111 is closer to the first reflecting surface 1211. Therefore, the light emitted by the first light source 111 is deflected by the first reflecting surface 1211 and can have a larger deflection angle, so that more light is concentrated on the upper half of the wall surface. Correspondingly, the light emitted by the second light source 211 is deflected by the second reflecting surface 2211 and can have a smaller deflection angle, so that more light is concentrated on the lower half of the wall surface. Thus, it is better to form a relatively high upper part light spot and a relatively low lower part light spot on the wall surface.

[0062] In this embodiment, the first lighting unit 100 and the second lighting unit 200 in the same lighting module 10 are arranged along the second direction Y, and the first lighting unit 100 is closer to the first side 11 than the second lighting unit 200.

[0063] Since the first lighting unit 100 and the second lighting unit 200 in the same lighting module 10 are arranged along the second direction Y, therefore, in a wall washer with a certain length, more first light sources 111 and second light sources 211 can be used. For a wall washer whose length is easily limited, multiple first light sources 111 and multiple second light sources 211 can both provide higher upper limit of brightness of light. Thus, on the basis of ensuring brightness, by adjusting the power of multiple first light sources 111 at the proximal end and the power of multiple second light sources 211 at the distal end, that is to say, making the power of the second light source 211 larger than that of the first light source 111, the brightness uniformity between the first lighting area I and the second lighting area II can be achieved, and thus the brightness uniformity of the light spots on the entire wall surface is good.

[0064] In addition, gratings 30 are provided between adjacent first light source modules 110 and between adjacent second light source modules 210. By providing gratings 30 between adjacent first light source modules 110 and between adjacent second light source modules 210, it is beneficial to reduce glare.

[0065] Further, the length dimensions of the first lighting unit 100 and the second lighting unit 200 in the first direction X are the same, and the numbers of the first light sources 111 and the second light sources 211 are the same.

[0066] In another embodiment, please refer to Figures 7 to 9, the first lighting unit 300 and the second lighting unit 400 in the same lighting module 40 are arranged along the first direction X. Thus, the depth dimension of the lamp is smaller and it is lighter.

[0067] In addition, a grille 50 is provided between adjacent first light source modules 310 and second light source modules 410, thereby facilitating the reduction of glare.

[0068] It should be noted that for the convenience of description and understanding, Figure 7 the housing, the first light-transmitting panel 330 and the second light-transmitting panel 430 of the wall washer light in another embodiment are not shown, Figure 8 and the first light-transmitting panel 330 and the second light-transmitting panel 430 are schematically shown.

[0069] Furthermore, the length of the first lighting unit 300 along the first direction X is less than the length of the second lighting unit 400 along the first direction X, and in the same lighting module 40, the number of first light sources is less than the number of second light sources.

[0070] On the basis that the distance between the first light source and the first reflecting surface in the second direction Y is less than the distance between the second light source and the second reflecting surface in the second direction Y, since the second light source is farther from the wall than the first light source, therefore, the brightness of a single second light source irradiating the wall is likely to be lower than that of the first light source. Thus, by making the number of second light sources more than the number of first light sources, the brightness uniformity between the first illumination area I and the second illumination area II can be achieved, thereby making the brightness uniformity of the light spots on the entire wall good.

[0071] Specifically, the first lighting unit 100 includes: a first light source module 110 and a first reflector 120.

[0072] Specifically, the first reflector 120 is an electroplated reflector that forms a stretching structure in the first direction X.

[0073] In some embodiments, the first light source 111 includes 4 lamp beads with different colors.

[0074] By performing mixed light modulation on these 4 lamp beads, such as PWM dimming, each first light source 111 can emit light that meets the target color, color temperature, and brightness.

[0075] The colors of the lamp beads of the first light source 111 can be blue, green, red, and yellow respectively, or can be blue, green, orange, and white, etc. The colors of the lamp beads in the first light source 111 can be configured according to the mixed light requirements.

[0076] In addition, the first light sources 111 in the same first light source module 110 can be controlled uniformly or separately. Thus, more abundant light control requirements can be met.

[0077] In this embodiment, the first light source module 110 includes two groups of first light sources 111.

[0078] In some embodiments, the first reflector 120 includes: a first reflecting portion 121.

[0079] The first reflecting surface 1211 is located on the surface of the first reflecting portion 121.

[0080] In some embodiments, the first reflector 120 further includes: a third reflecting portion 123.

[0081] The third reflecting portion 123 extends obliquely from the first reflecting portion 121 toward the first side 11. Correspondingly, the first lighting unit 110 is further provided with a third reflecting surface 1231 located on the surface of the third reflecting portion 123. The third reflecting surface 1231 is connected to the bottom of the first reflecting surface 1211 and is inclined toward the first side 11. Thus, it better helps the first lighting unit 110 deflect more light to the upper half area of the wall surface.

[0082] In some embodiments, the first reflector 120 further includes: a fourth reflecting portion 122.

[0083] The first reflecting portion 121 and the fourth reflecting portion 122 are arranged along the second direction Y. Correspondingly, the first lighting unit 110 is further provided with a fourth reflecting surface 1221 located on the surface of the fourth reflecting portion 122. The fourth reflecting surface 1221 is disposed opposite to the first reflecting surface 1211. Among them, the fourth reflecting surface 1221 is an arc surface recessed toward the first side 11.

[0084] In some embodiments, the bottom end of the fourth reflecting surface 1221 is higher than the bottom end of the third reflecting surface (1231). Therefore, it can reduce the occlusion of the light emitted after being deflected by the first reflecting surface 1211. Thus, it is beneficial to make the light more concentrated in the upper half of the wall surface.

[0085] Preferably, the bottom end of the fourth reflecting surface 1221 is flush with the bottom end of the first reflecting surface 1211.

[0086] In some embodiments, the first reflector 120 further includes: a first reflection limiting portion 124.

[0087] The first reflection limiting portion 124 extends from the bottom edge of the fourth reflecting portion 122 toward the first side 11.

[0088] In some embodiments, the first lighting unit 100 further includes: a first light transmissive panel 130.

[0089] The material of the first light transmissive panel 130 is an optical grade transparent material such as optical grade transparent PMMA material, transparent PC material or glass.

[0090] The first light-transmitting panel 130 is disposed at the bottom of the first reflector 120. Through the first light-transmitting panel 130, the light directly emitted by the first lighting unit 100 to the bottom of the first reflector 120 and the light reflected by the first reflector 120 to the bottom of the first reflector 120 can be diffused, so that the light output of the first lighting unit 100 is more uniform.

[0091] On both side edges of the first light-transmitting panel 130 along the second direction Y, a first light-transmitting limiting portion 131 and a second light-transmitting limiting portion 132 extending toward the first reflector 120 are respectively connected.

[0092] Wherein, the top end of the first light-transmitting limiting portion 131 is in limiting cooperation with the first reflection limiting portion 124, and the bottom end of the third reflection portion 123 is in limiting cooperation with the surface of the first light-transmitting panel 130 facing the first reflector 120. In addition, the surface of the second light-transmitting limiting portion 132 facing the first side 11 is a limiting inclined surface adapted to the third reflection portion 123, and the surface of the third reflection portion 123 facing away from the first side 11 is in limiting cooperation with the limiting inclined surface. Thus, the relative position between the first reflector 120 and the first light-transmitting panel 130 is in limiting cooperation in multiple directions. Among them, the third reflection portion 123 takes into account both limiting and reflection. Moreover, in cooperation with the connection between the first light-transmitting panel 130 and the housing 30 of the wall washer, the first reflector 120 can also be fixed.

[0093] In some embodiments, the surface of the first light-transmitting panel 130 facing the first reflector 120 is a plane. In addition, the surface of the first light-transmitting panel 130 facing away from the first reflector 120 is the first light-emitting surface, and the first light-emitting surface is the light-emitting surface of the first lighting unit 100. And a first microstructure is formed on the first light-emitting surface. Through the first microstructure, the light incident on the first light-transmitting panel 130 can be better mixed, thereby further improving the uniformity of the light irradiated on the wall.

[0094] Specifically, the first microstructure is an etching pattern formed on the first light-emitting surface, and the first microstructure is composed of a plurality of microstructural sawteeth in a stretched shape.

[0095] In some embodiments, the second lighting unit 200 includes: a second light source module 210 and a second reflector 220.

[0096] Specifically, the second reflector 220 is an electroplated reflector having a stretched structure in the first direction X.

[0097] Preferably, the topmost end of the second reflector 220 and the topmost end of the first reflector 120 are at the same height, and the bottommost end of the second reflector 220 and the bottommost end of the first reflector 120 are at the same height.

[0098] In some embodiments, the second light source 211 includes four light beads with different colors.

[0099] By performing mixed light modulation on the four light beads, such as PWM dimming, each second light source 211 can emit light that meets the target color, color temperature, and brightness.

[0100] The colors of the light beads of the second light source 211 can be blue, green, red, and yellow respectively, or can be blue, green, orange, and white respectively, etc. The colors of the light beads in the second light source 211 can be configured according to the mixed light requirements. In addition, since the light emitted by the first light source 111 and the second light source 211 is obtained by mixing and dimming four light beads with different colors, the first light source 111 and the second light source 211 can be light sources with the same light beads, and by dimming and mixing the four light beads of the first light source 111 and the four light beads of the second light source respectively, the colors and / or color temperatures of the light emitted by the second light source module 210 and the first light source module 110 can be made different. Of course, different light beads can also be used between the first light source 111 and the second light source 211.

[0101] In addition, the second light sources 211 in the same second light source module 210 can be controlled uniformly or separately. Thus, more diverse light control requirements can be met.

[0102] In this embodiment, the second light source module 210 includes two groups of second light sources 211.

[0103] In some embodiments, the second reflector 220 includes: a second reflecting portion 221.

[0104] The second reflecting surface 2211 is located on the surface of the second reflecting portion 221.

[0105] In some embodiments, the second reflector 220 further includes: a fifth reflecting portion 222.

[0106] The second reflecting portion 221 and the fifth reflecting portion 222 are arranged along the second direction Y. Correspondingly, the second lighting unit 200 is further provided with a fifth reflecting surface 2221 located on the surface of the fifth reflecting portion 222. The fifth reflecting surface 2221 is arranged opposite to the second reflecting surface 2211. Among them, the fifth reflecting surface 2221 is an arc surface that is concave toward the first side 11, and the fifth slope is greater than the fourth slope.

[0107] Among them, the fourth slope refers to the slope of the connection line L4 (as shown in Figure 3 shown) between the two ends of the arc projection of the fourth reflecting surface 1221 on the depth plane, and the fifth slope refers to the slope of the connection line L5 (as shown in Figure 3 shown) between the two ends of the arc projection of the fifth reflecting surface 2221 on the depth plane.

[0108] Since in the first lighting unit 100 and the second lighting unit 200 of each lighting module 10, the fifth slope is greater than the fourth slope, therefore, the light emitted by the first light source module 110 and the light emitted by the second lighting unit 200 can be better controlled, and further, the light of the first lighting unit 100 is more deflected to the upper half area of the wall surface, and further, the light of the second lighting unit 200 is more deflected to the lower half area of the wall surface.

[0109] In some embodiments, the second lighting unit 200 further includes: a second light-transmitting panel 230.

[0110] The material of the second light-transmitting panel 230 is an optical-grade transparent material such as optical-grade transparent PMMA material, transparent PC material or glass.

[0111] The second light-transmitting panel 230 is disposed at the bottom of the second reflector 220.

[0112] Through the second light-transmitting panel 230, the light directly incident on the bottom of the second reflector 220 by the second lighting unit 200 and the light reflected by the second reflector 220 to the bottom of the second reflector 220 can be diffused, so that the light output of the second lighting unit 200 is more uniform.

[0113] In some embodiments, the surface of the second light-transmitting panel 230 facing the second reflector 220 is a plane. In addition, the surface of the second light-transmitting panel 230 facing away from the second reflector 220 is a second light-emitting surface, and the second light-emitting surface is the light-emitting surface of the second lighting unit 200, and a second microstructure is formed on the second light-emitting surface. Through the second microstructure, the light incident on the second light-transmitting panel 230 can be better mixed, so that the uniformity of the light irradiated on the wall surface is further improved.

[0114] Specifically, the second microstructure is an etching pattern formed on the second light-emitting surface, and the second microstructure is composed of a plurality of microstructural sawteeth in a stretched shape.

[0115] In this embodiment, the wall washer further includes: a housing 20.

[0116] The housing 20 is formed with a first receiving groove 21 and a second receiving groove 22.

[0117] Wherein, the first receiving groove 21 and the second receiving groove 22 are arranged adjacent to each other, the first lighting unit 100 is fixed in the first receiving groove 21, and the second lighting unit 200 is fixed in the second receiving groove 22. Correspondingly, the first light-transmitting limiting portion 131 and the second light-transmitting limiting portion 132 extend towards the bottom of the first receiving groove 21.

[0118] In this embodiment, hooks are provided at the openings of the first receiving groove 21 and the second receiving groove 22, and protrusions are provided on the inner walls of the first receiving groove 21 and the second receiving groove 22. Therefore, single-sided or double-sided slots can be formed on the wall of the first receiving groove 21, and single-sided or double-sided slots can be formed on the wall of the second receiving groove 22. Thus, the first light-transmitting limiting portion 131 can be lapped on the hook at the opening of the first receiving groove 21, and at least one side edge of the first light-transmitting limiting portion 131 can be inserted into the slot formed on the wall of the first receiving groove 21. On this basis, with the limiting cooperation between the first light-transmitting limiting portion 131 and the first reflector 120, the first light-transmitting limiting portion 131 and the first reflector 120 can be more firmly fixed in the first receiving groove 21. Similarly, at least one side edge of the second light-transmitting limiting portion 132 can be inserted into the slot formed on the wall of the second receiving groove 22, so that the first light-transmitting limiting portion 131 and the first reflector 120 can be fixed in the first receiving groove 21.

[0119] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various combinations, changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
