Description

Technical Field

[0001] This invention relates to a wall washer light fixture, belonging to the field of lighting technology. Background Technology

[0002] Most existing wall washer lights can only produce a single color temperature or color wash effect, resulting in poor visual appeal. To create a contrasting color lighting effect on the wall, two sets of lights, one above and one below, need to be installed, which not only increases costs but also easily creates a cluttered overall appearance. Furthermore, the need to install two sets of lights also limits and challenges installation conditions.

[0003] In view of this, it is indeed necessary to improve the existing wall washer lights to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wall washer light fixture that can not only achieve contrasting color lighting, but also use a single reflector to provide zoned lighting to achieve different lighting effects.

[0005] To achieve the above objectives, the present invention provides a wall washer light fixture, comprising:

[0006] The lamp body has a mounting cavity and a light outlet communicating with the mounting cavity;

[0007] A light source module, assembled in a mounting cavity, includes at least two light-emitting elements arranged side by side;

[0008] At least two optical elements are correspondingly arranged with at least two light-emitting elements, configured to emit light emitted by the at least two light-emitting elements along their respective predetermined paths; and

[0009] The reflector, assembled within the mounting cavity, has a reflective surface facing the light source module.

[0010] The reflective surface includes at least two reflective areas corresponding to at least two light-emitting elements. These at least two reflective areas are configured to receive light emitted from at least two optical elements, respectively, so that the light emitted from the at least two optical elements can be guided through light-emitting ports to at least two light-receiving surfaces. This configuration allows for contrasting color lighting of the wall surface to be achieved with a single wall washer luminaire, saving installation space.

[0011] As a further improvement of the present invention, at least two reflective areas include a first reflective area and a second reflective area, both of which are curved surfaces and recessed in the direction away from the light source module. This configuration gives the reflector a larger reflective surface, improving reflection efficiency.

[0012] As a further improvement of the present invention, the lamp body includes a first wall and a second wall disposed opposite to each other, and a connecting wall connecting the first wall and the second wall. The mounting cavity is formed by the first wall, the second wall and the connecting wall, and the light outlet is formed between the first wall and the second wall. This arrangement makes the light outlet larger, allowing more light to be emitted from the light outlet, thereby achieving wall washing lighting for a larger area of ​​the wall surface.

[0013] As a further improvement of the present invention, the first end of the reflector begins near the second wall of the connecting wall, and the second end ends near the light outlet of the first wall, with the light source module disposed on the second wall. This arrangement facilitates the reflection of light emitted from the light source module by the reflector before it exits through the light outlet, thereby realizing the function of a wall washer light.

[0014] As a further improvement of the present invention, the connecting wall and the first wall are respectively provided with a locking part for locking the reflector, and the first end and the second end of the reflector are respectively locked into the corresponding locking part. This arrangement facilitates the replacement or adjustment of the reflector according to the light distribution requirements of the wall washer light fixture.

[0015] As a further improvement of the present invention, the second wall is provided with multiple mounting surfaces, and at least two light-emitting elements are mounted on the corresponding mounting surfaces.

[0016] As a further improvement of the present invention, at least two optical components are any one or a combination of a polarizing lens, a hyperboloid lens, a TIR lens, and a reflector. With this configuration, the at least two optical components can adjust the angle of the light emitted from the at least two light-emitting components, i.e., reduce the light emission angle, so that the light emitted from the at least two light-emitting components falls on the corresponding light-receiving surface.

[0017] As a further improvement of the present invention, of the at least two light-emitting elements, at least one light-emitting element is mounted parallel to the second wall on the corresponding mounting surface, or at least one light-emitting element is mounted obliquely on the corresponding mounting surface, wherein the selection of at least two optical elements is determined in relation to the mounting state of the at least two light-emitting elements.

[0018] As a further improvement of the present invention, at least two light-emitting elements are mounted parallel to the second wall on the corresponding mounting surface, and at least two optical elements are polarizing lenses. With this configuration, at least two light-emitting elements can share a single light source board, resulting in a simpler lamp body structure and better heat dissipation.

[0019] As a further improvement of the present invention, at least two light-emitting elements each include a light source plate and multiple light sources arranged on the light source plate, and the light sources on different light source plates are of different colors and / or multiple colors of light sources are provided on the same light source plate. This arrangement enables the achievement of contrasting color lighting effects of multiple colors.

[0020] The beneficial effects of this invention are as follows: The wall washer light fixture of this invention, by providing at least two light-emitting elements and at least two optical elements corresponding to the light-emitting elements, allows the at least two optical elements to emit light emitted from the at least two light-emitting elements along their respective predetermined paths. Furthermore, by forming at least two reflective areas corresponding to the at least two light-emitting elements on the reflective surface of the reflector, the at least two reflective areas can respectively receive light emitted through the at least two optical elements, enabling the light emitted from the at least two optical elements to be guided through the light outlet to the at least two light-receiving surfaces, thus creating a contrasting color effect. Compared to the prior art, the wall washer light fixture of this invention not only achieves contrasting color lighting but also utilizes a single reflector for zoned lighting, achieving different lighting effects, and is not limited by installation conditions.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Please see Figures 1-22 As shown, this invention discloses a wall washer light fixture 100, including a lamp body 1, a light source module 2 and a reflector 3 mounted on the lamp body 1, and at least two optical components 4 cooperating with the light source module 2. The wall washer light fixture 100 of this invention is preferably a wall washer lamp used for wall lighting. This single wall washer light fixture 100 can achieve contrasting color lighting on the wall, requires little installation space, and also provides more structural design space for wall decoration. The wall washer light fixture 100 can also utilize a single reflector 3 to achieve different lighting effects in zone lighting, and the wall washer light fixture 100 is not easily restricted by installation conditions.

[0048] It should be emphasized that the main feature of this application lies in the optical design of the wall washer light fixture 100. Therefore, in actual products, it may also include end caps at both ends of the light body, a power drive part inside or outside the light body, a mounting bracket for mounting the light body, etc. These structures do not affect the main inventive purpose of this application, and therefore will not be described in detail in this application text.

[0049] Example 1:

[0050] like Figures 1-5As shown, the lamp body 1 has a mounting cavity 11 extending along its longitudinal direction and a light outlet 12 communicating with the mounting cavity 11. The light source module 2 and the reflector 3 are both assembled within the mounting cavity 11. The light source module 2 includes at least two light-emitting elements arranged side-by-side, such as a first light source element 21 and a second light source element 22. For ease of explanation, the following embodiments will use the side-by-side first light source element 21 and the second light source element 22 as examples. The at least two optical elements 4 include a first optical element 41 assembled to the first light source element 21 and a second optical element 42 assembled to the second light source element 22. The first optical element 41 and the second optical element 42 are configured to guide the light emitted by the first light source element 21 and the second light source element 22 respectively to the reflector 3 along a predetermined optical path. The reflective surface 30 of the reflector 3 faces the light source module 2, and the reflective surface 30 includes at least two reflective areas corresponding to the at least two light-emitting elements. Specifically, the reflective surface 30 includes a first reflective area 31 for receiving and guiding light emitted from the first light source 21 and a second reflective area 32 for receiving and guiding light emitted from the second light source 22, so that the light emitted from the first light source 21 and the second light source 22 can be guided to the two light receiving surfaces respectively through the light outlet 12.

[0051] Combination Figure 5 As shown, the light emitted from the first light source 21 passes through the first optical element 41 and is emitted into the first reflective area 31. The light is then reflected by the first reflective area 31 to the light outlet 12 and emitted onto the first receiving surface, forming high beam. The light emitted from the second light source 22 passes through the second optical element 42 and is emitted into the second reflective area 32. The light is then reflected by the second reflective area 32 to the light outlet 12 and emitted onto the second receiving surface, forming low beam. Both the first and second receiving surfaces are preferably walls. The light emitted from the first light source 21 illuminates the wall at a position away from the lamp body 1, i.e., the first receiving surface, and forms high beam on the first receiving surface. The light emitted from the second light source 22 illuminates the wall at a position closer to the lamp body 1, i.e., the second receiving surface, and forms low beam on the second receiving surface. At this time, the light emitted from the first light source 21 and the light emitted from the second light source 22 create a contrasting color lighting effect on the wall.

[0052] In Embodiment 1, the lamp body 1 is preferably elongated. Of course, in other alternative embodiments, the lamp body 1 can also be other shapes, and there is no limitation on this.

[0053] Specifically, the lamp body 1 includes a first wall 13 and a second wall 14 disposed opposite to each other, and a connecting wall 15 connecting the same end of the first wall 13 and the second wall 14. The connecting wall 15 is preferably perpendicular to the first wall 13 and the second wall 14. The mounting cavity 11 is formed by the first wall 13, the second wall 14, and the connecting wall 15, and the light outlet 12 is formed between the other end of the first wall 13 and the other end of the second wall 14. The first end of the reflector 3 starts at a position on the connecting wall 15 near the second wall 14, and the second end ends at a position on the first wall 13 near the light outlet 12. The light source module 2 is disposed on the second wall 14. The light emitted from the light source module 2 is reflected by the reflector 3 to form an outgoing light that exits through the light outlet 12, thereby realizing the function of a wall washer light.

[0054] Preferably, the width of the second wall 14 is smaller than the width of the first wall 13, and approximately half the width of the first wall 13, thereby increasing the size of the light outlet 12 and allowing more light to be emitted from the light outlet 12, thus achieving wall washing lighting over a larger area of ​​the wall surface.

[0055] The second wall 14 has a protruding mounting portion 141, which has multiple mounting surfaces for mounting at least two light-emitting elements. In Embodiment 1, the mounting surfaces include a first inclined surface 1411 and a second inclined surface 1412 that are close to each other, extending along the longitudinal direction of the lamp body 1. The first inclined surface 1411 is located near the connecting wall 15, and the second inclined surface 1412 is located near the light outlet 12. A first light source element 21 is mounted on the first inclined surface 1411, and a second light source element 22 is mounted on the second inclined surface 1412. Both the first light source element 21 and the second light source element 22 include a light source plate 210 and one or more light sources 211 evenly arranged on the light source plate 210. The light source plate 210 is attached to the first inclined surface 1411 and the second inclined surface 1412.

[0056] It is understandable that when three or more light-emitting elements are mounted on the mounting part 141, the mounting part 141 may be provided with a corresponding number of mounting surfaces.

[0057] In Embodiment 1, the first inclined surface 1411 and the second inclined surface 1412 have the same tilt angle. Of course, the tilt angles of the first inclined surface 1411 and the second inclined surface 1412 can also be adjusted according to the light distribution requirements of the wall washer luminaire 100. For example, if the first optical element 41 and the second optical element 42 are of the same type, the tilt angle of the first inclined surface 1411 can be adjusted so that the tilt angle of the first inclined surface 1411 is not equal to the tilt angle of the second inclined surface 1412. Figure 6 and Figure 7 As shown. At this time, it is possible to change the light distribution of high beam and low beam, that is, to change the ratio of the wall washing area or the brightness intensity of high beam and low beam.

[0058] Of course, when the inclination angles of the first inclined plane 1411 and the second inclined plane 1412 are the same, the types of the first optical element 41 and the second optical element 42 can also be set to be different to change the light distribution of the high beam and the low beam, that is, to change the ratio of the wall washing area or the brightness intensity of the high beam and the low beam, specifically as follows: Figure 8 and Figure 9 As shown.

[0059] Preferably, the light sources 211 on different light source panels 210 are of different colors and / or the same light source panel 210 has multiple colors of light sources 211. Specifically, firstly, when the light sources 211 on different light source panels 210 are of different colors, while the light sources 211 on the same light source panel 210 are of the same color, the light source module 2 will emit two colors of light, making the high beam and low beam colors different, thus presenting two colors on the wall and achieving a contrasting color effect. Secondly, when the light sources 211 on different light source panels 210 are of different colors and the same light source panel 210 has multiple colors of light sources 211, by controlling the proportion of different colors of light sources 211 on each light source panel 210, the colors of the high beam and low beam can be adjusted. This not only achieves different colors for the high beam and low beam, but also allows the high beam to contain multiple colors, and the low beam to also contain multiple colors, thus presenting multiple colors on the wall and achieving a contrasting color effect. Third, when multiple colors of light sources 211 are provided on the same light source board 210, and the colors of light sources 211 on different light source boards 210 correspond to the same color, the high beam and low beam of the light sources 211 of the same color on different light source boards 210 are connected, and the high beam and low beam have the same color. The different colors of light sources 211 on the same light source board 210 present multiple colors on the wall.

[0060] The reflector 3 can be integrally formed with the lamp body 1, or it can be a separate component installed in the lamp body 1. In Embodiment 1, the connecting wall 15 and the first wall 13 are respectively provided with a latching part 16 for latching the reflector 3, and the first end and the second end of the reflector 3 are respectively latched into the corresponding latching part 16. Optionally, the latching part 16 protrudes from the corresponding connecting wall 15 or the first wall 13, and a groove 160 is formed between the latching part 16 and the corresponding connecting wall 15 or the first wall 13. The first end and the second end of the reflector 3 are inserted into the corresponding groove 160, that is, the reflector 3 is installed by limiting the two ends of the reflector 3. The first reflection area 31 and the second reflection area 32 are arc surfaces and are recessed in the direction away from the light source module 2. The reflector 3 exposes a larger area for reflection, improving the reflection efficiency. It also facilitates the replacement or adjustment of the reflector 3 according to the light distribution requirements of the wall washer lamp 100.

[0061] In Embodiment 1, the first reflective area 31 and the second reflective area 32 are connected, with the first reflective area 31 located at the first end of the reflector 3 and the second reflective area 32 located at the second end of the reflector 3. The first light source 21 and the second light source 22 are arranged at an angle, and the first optical element 41 and the second optical element 42 are respectively mounted on the light source plate 210 and cover the outside of the light source 211. The first optical element 41 can adjust the angle of the light emitted from the light source 211 of the first light source 21, i.e., reduce the light emission angle, so that the light emitted from the light source 211 of the first light source 21 falls on the first reflective area 31. The second optical element 42 can adjust the angle of the light emitted from the light source 211 of the second light source 22, i.e., reduce the light emission angle, so that the light emitted from the light source 211 of the second light source 22 falls on the second reflective area 32, ensuring optical efficiency.

[0062] like Figures 8-15 As shown, the first optical element 41 and the second optical element 42 are any one or a combination of hyperboloid lenses, TIR lenses, and reflectors. For example: Figure 8 In the middle, both the first optical element 41 and the second optical element 42 are hyperboloid lenses; Figure 10 In the middle, both the first optical element 41 and the second optical element 42 are TIR lenses; Figure 12 In the middle, both the first optical element 41 and the second optical element 42 are reflectors; Figure 14 In the middle, the first optical component 41 is a hyperboloid lens, and the second optical component 42 is a TIR lens; Figure 15 In this design, the first optical element 41 is a reflector, and the second optical element 42 is a hyperboloid lens. As long as the angle of light emission can be adjusted, there are no restrictions on this.

[0063] When both the first optical element 41 and the second optical element 42 are preferably hyperboloid lenses, the light distribution can be adjusted by changing the curvature of the hyperboloid lenses to make the exit angles of the two hyperboloid lenses different. In this way, the light distribution of high beam and low beam can be changed, that is, the ratio of the wall washing area or the brightness intensity of high beam and low beam can be changed.

[0064] Combination Figure 4 and Figure 5 As shown, when the first optical element 41 and the second optical element 42 correspond one-to-one with the first reflective area 31 and the second reflective area 32, the distribution of high beam and low beam can be adjusted by adjusting the curvature of the reflector 3 to change the ratio of the wall-washing area or the brightness intensity of the high beam and low beam. To obtain the complete curved shape of the reflector 3, a fourth-order Bézier curve is introduced. This fourth-order Bézier curve consists of four control points A, B, C, and D, where A and D are the starting and ending points of the curve, and B and C are the control points of the curve. The formula for the fourth-order Bézier curve can be expressed as B(t) = (1-t). 3 P0+3t(1-t)2 P1+3t 2 (1-t)P2+t 3 P3, t∈[0,1]. Here, B(t) is a point on the curve, t is a parameter between 0 and 1, and P0, P1, P2, and P3 are the coordinates of the control points. In the high beam, P0 = (-20, 0), P1 = (-17.05, 6.94), P2 = (-7, 20.92), P3 = (0, 26.34); in the low beam, P0 = (0, 26.337), P1 = (9.84, 34.19), P2 = (26.66, 41.92), P3 = (52, 36.5). These two Bézier curves represent the complete reflector's curve shape.

[0065] Of course, the first reflective area 31 and the second reflective area 32 of the reflective surface 30 can be treated with different processes to adjust the light distribution of high beam and low beam. For example, films with different reflectivities can be deposited on the first reflective area 31 and the second reflective area 32 to adjust the light. Alternatively, reflective films with different Gaussian properties can be deposited to adjust the light, such as the first reflective area 31 having a specular property and the second reflective area 32 having a diffuse reflection property, in order to change the proportion of the wall-washing area or the brightness intensity of the high beam and low beam.

[0066] Example 2

[0067] like Figures 16-19 As shown, the difference from Embodiment 1 is that the light source module 2 further includes a third light source 23 located between the first light source 21 and the second light source 22, and the reflective surface 30 correspondingly includes a third reflective area 33 located between the first reflective area 31 and the second reflective area 32. Specifically, the mounting surface of the mounting part 141 further includes a connecting plane 1413 for connecting the first inclined surface 1411 and the second inclined surface 1412, and the third light source 23 is mounted on the connecting plane 1413. The first reflective area 31, the third reflective area 33, and the second reflective area 32 are connected in sequence, and the optical component 4 further includes a third optical component 43 assembled on the third light source 23. The light emitted from the third light source 23 is emitted through the third optical component 43 to the third reflective area 33, reflected by the third reflective area 33 to the light outlet 12 and emitted to the third receiving surface, forming a connecting light. The third receiving surface is located between the first receiving surface and the second receiving surface, and the connecting light connects the high beam and the low beam, forming a multi-color contrasting illumination effect.

[0068] Example 3

[0069] like Figures 20-22As shown, the difference from Embodiment 1 is that the first light source element 21 and the second light source element 22 are directly laid side by side on the second wall 14, that is, they are both mounted parallel to the second wall 14 on their respective mounting surfaces, and both the first optical element 41 and the second optical element 42 are polarizing lenses. In Embodiment 3, the first light source element 21 and the second light source element 22 preferably share a single light source plate 210, on which two rows of light sources 211 are arranged in a linear array. The first optical element 41 and the second optical element 42 are mounted on the light source plate 210 and respectively cover the outside of the corresponding light source 211. The light emitted from the first light source 21 is polarized and its emission angle reduced by the first optical element 41 before exiting into the first reflection area 31. The light is then reflected by the first reflection area 31 to the light outlet 12 and emitted onto the first receiving surface, forming high beam. The light emitted from the second light source 22 is polarized and its emission angle reduced by the second optical element 42 before exiting into the second reflection area 32. The light is then reflected by the second reflection area 32 to the light outlet 12 and emitted onto the second receiving surface, forming low beam. In Embodiment 3, the first light source 21 and the second light source 22 can be placed flat, eliminating the need for a mounting portion 141 on the second wall 14. The mounting surface is preferably the wall surface of the second wall 14, resulting in a simpler structure for the lamp body 1 and better heat dissipation.

[0070] Of course, in other embodiments, the first light source 21 can be arranged flat on the second wall 14, and the second light source 22 can be arranged obliquely on the corresponding mounting surface of the mounting portion 141. In this case, the first optical element 41 is a polarizing lens, and the second optical element 42 is any one of a hyperboloid lens, a TIR lens, or a reflector. Alternatively, the first light source 21 can be arranged obliquely on the corresponding mounting surface of the mounting portion 141, and the second light source 22 can be flat on the second wall 14. In this case, the first optical element 41 is any one of a hyperboloid lens, a TIR lens, or a reflector, and the second optical element 42 is a polarizing lens.

[0071] In short, the selection of the first optical element 41 and the second optical element 42 varies depending on the installation state of the first light source 21 and the second light source 22. That is, the selection of at least two optical elements 4 is determined in relation to the installation state of at least two light-emitting elements.

[0072] In summary, the wall washer light fixture 100 of the present invention, by setting a first light source 21 and a second light source 22, and assembling a first optical element 41 on the first light source 21 and a second optical element 42 on the second light source 22, and further by forming a first reflective area 31 corresponding to the first light source 21 and a second reflective area 32 corresponding to the second light source 22 on the reflective surface 30 of the reflector 3, allows light emitted from the first light source 21 to pass through the first optical element 41 to the first reflective area 31, and then be reflected from the first reflective area 31 to the light outlet 12 and emitted to the corresponding receiving surface, forming high beam; light emitted from the second light source 22 can pass through the second optical element 42 to the second reflective area 32, and then be reflected from the second reflective area 32 to the light outlet 12 and emitted to the corresponding receiving surface, forming low beam. Compared with the prior art, the present invention can achieve contrasting color lighting with a single wall washer light fixture 100, and can use a single reflector 3 to perform zoned lighting to achieve different lighting effects, and is not limited by installation conditions.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
