Abstract
Description
Technical Field
[0001] This application belongs to the field of lighting fixture design technology, specifically relating to a lighting unit and a lighting fixture. Background Technology
[0002] Lighting fixtures are widely used in various settings, such as wall washer lights. A lighting fixture typically has at least one illumination unit, which, when used in a wall washer scenario, illuminates the wall. The illumination units in related technologies project only one color of light onto the wall, thus illuminating it. This results in a relatively simple lighting effect, making it difficult to achieve a richer and more varied lighting experience. Utility Model Content
[0003] This utility model discloses a lighting unit and lighting fixture to solve the problem that the lighting units involved in related technologies have relatively simple lighting effects.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: In a first aspect, this application discloses a lighting unit, which includes a housing, a light source assembly, and a reflective assembly, wherein: The housing has an interconnected inner cavity and a light-emitting hole. The light source assembly and the reflection assembly are both disposed in the inner cavity. The light source assembly includes a first light source and a second light source. The reflection assembly includes a first reflector and a second reflector. The first reflector is opposite to the first light source, and the second reflector is opposite to the second light source. The first end of the first reflector is connected to the first light source, and the second end of the first reflector is opposite to the light-emitting hole and spaced apart from the first light source by a first distance. The first reflector is used to receive the first light emitted by the first light source and reflect at least a portion of the first light through the light-emitting hole to the first region. The first end of the second reflector is connected to the second light source, and the second end of the second reflector is opposite to the light-emitting aperture and spaced apart from the second light source by a second distance. The second reflector is used to receive the second light emitted by the second light source and reflect at least a portion of the second light through the light-emitting aperture to the second region. The first distance is greater than the second distance, and the first region and the second region do not overlap at least partially.
[0005] Secondly, this application discloses a lighting fixture, which includes the lighting unit described above. When there are multiple lighting units, the multiple lighting units are interconnected.
[0006] The technical solution adopted in this utility model can achieve the following technical effects: The lighting unit disclosed in this application improves the structure of lighting units related to the relevant technology by setting a reflective component, setting the light source component to include a first light source and a second light source, setting the reflective component to include a first reflector and a second reflector, setting the first reflector to be opposite to the first light source, the second reflector to be opposite to the second light source, setting the first end of the first reflector to be connected to the first light source, the second end of the first reflector to be spaced apart from the first light source by a first distance, the first end of the second reflector to be connected to the second light source, and the second end of the second reflector to be spaced apart from the second light source by a second distance. This allows the first reflector to receive the first light emitted by the first light source and reflect at least a portion of the first light out of the second end of the first reflector, so that at least a portion of the first light passes through the light outlet hole and is projected outside the housing, thereby projecting onto the first area. Similarly, the second reflector receives the second light emitted by the second light source and reflects at least a portion of the second light out of the second end of the second reflector, so that at least a portion of the second light passes through the light outlet hole and is projected outside the housing, thereby projecting onto the second area.
[0007] Furthermore, by setting the first distance to be greater than the second distance, the first light rays projected onto the outside of the housing are farther away from the housing than the second light rays projected onto the outside of the housing, while the second light rays projected onto the outside of the housing are closer to the housing than the first light rays projected onto the outside of the housing. This results in the first area being farther away from the housing than the second area, and the first area and the second area not overlapping at least partially. This allows the lighting unit to project at least a portion of the first light rays and at least a portion of the second light rays onto the first area and the second area, which are at different distances from the lighting unit, thereby achieving a richer lighting effect.

[0013] Please refer to Figures 1 to 10 This application discloses a lighting unit, which includes a housing 100, a light source assembly 200, and a reflector assembly 300.
[0014] The housing 100 is the basic component of the lighting unit, providing a mounting base for other components of the lighting unit, including the light source assembly 200 and the reflector assembly 300. Furthermore, the housing 100 also forms functional spaces or structures, such as the inner cavity 110 and the light-emitting aperture 120 described later.
[0015] The light source assembly 200 is the core component in the lighting unit that realizes the lighting function, and the reflector assembly 300 is the core component in the lighting unit that realizes the light path effect. The housing 100 has an interconnected inner cavity 110 and a light-emitting aperture 120. Both the light source assembly 200 and the reflector assembly 300 are disposed within the inner cavity 110. The light source assembly 200 includes a first light source 210 and a second light source 220. The first light source 210 emits a first ray A, and the second light source 220 emits a second ray B. The reflector assembly 300 includes a first reflector 310 and a second reflector 320. The first reflector 310 is opposite to the first light source 210, thereby reflecting the first ray A, and the second reflector 320 is opposite to the second light source 220, thereby reflecting the second ray B.
[0016] The first end of the first reflector 310 is connected to the first light source 210, and the second end of the first reflector 310 is opposite to the light outlet 120 and spaced apart from the first light source 210 by a first distance, that is, the first end of the first reflector 310 is close to the first light source 210, and the second end of the first reflector 310 is far away from the first light source 210. The first reflector 310 is used to receive the first light ray A emitted by the first light source 210 and reflect at least a portion of the first light ray A through the light outlet 120 to the first region 510. The first reflector 310 can reflect at least a portion of the first light ray A out of the second end of the first reflector 310, so that at least a portion of the first light ray A passes through the light outlet 120 and is projected outside the housing 100, so that at least a portion of the first light ray A is projected to the first region 510, thereby illuminating the first region 510.
[0017] Specifically, the first light source 210 may include at least one first light source body 211 and a first circuit board 212. The first light source body 211 may be disposed on the first circuit board 212 by means of bonding, welding or other methods. The first end of the first reflector 310 may be connected to the first circuit board 212. The first light source body 211 may be an LED lamp, and the first circuit board 212 may be a printed circuit board or a rigid-flex board. This application embodiment does not limit this.
[0018] The first end of the second reflector 320 is connected to the second light source 220, and the second end of the second reflector 320 is opposite to the light exit hole 120 and spaced apart from the second light source 220 by a second distance, that is, the first end of the second reflector 320 is close to the second light source 220, and the second end of the second reflector 320 is far away from the second light source 220. The second reflector 320 is used to receive the second light ray B emitted by the second light source 220 and reflect at least a portion of the second light ray B through the light exit hole 120 to the second region 520. The second reflector 320 can reflect at least a portion of the second light ray B out of the second end of the second reflector 320, so that at least a portion of the second light ray B passes through the light exit hole 120 and is projected outside the housing 100, so that at least a portion of the second light ray B is projected to the second region 520, thereby illuminating the second region 520.
[0019] Specifically, the second light source 220 may include at least one second light source body 221 and a second circuit board 222. The second light source body 221 may be disposed on the second circuit board 222 by means of bonding, welding or other methods. The second end of the second reflector 320 may be connected to the second circuit board 222. The second light source body 221 may be an LED lamp, and the second circuit board 222 may be a printed circuit board or a rigid-flex board. This application embodiment does not limit this.
[0020] Meanwhile, the first distance is greater than the second distance, and the first region 510 and the second region 520 do not overlap at least partially. The first distance being greater than the second distance allows the first ray A projected onto the outside of the housing 100 to be farther away from the housing 100 than the second ray B projected onto the outside of the housing 100, while the second ray B projected onto the outside of the housing 100 is closer to the housing 100 than the first ray A projected onto the outside of the housing 100. This results in the first region 510 and the second region 520 not overlapping at least partially, and the distribution direction of the first region 510 and the second region 520 can be parallel to the central axis direction of the light-emitting aperture 120.
[0021] Specifically, the first region 510 and the second region 520 can be distributed on the light receiving surface 500, that is, the light receiving surface 500 can include the first region 510 and the second region 520. The first reflector 310 and the second reflector 320 can be opposite to the light receiving surface 500, so that the first reflector 310 and the second reflector 320 can respectively reflect at least part of the first light ray A and at least part of the second light ray B through the light exit hole 120 to the light receiving surface 500. The light receiving surface 500 can be a wall surface. The specific type of the light receiving surface 500 is not limited in the embodiments of this application.
[0022] It should be noted that the first distance can be the distance between the second end of the first reflector 310 and the first light source 210 in the distribution direction of the first reflector 310 and the first light source 210. The distribution direction of the first reflector 310 and the first light source 210 can be perpendicular to the central axis direction of the light outlet aperture 120. The second distance can be the distance between the second end of the second reflector 320 and the second light source 220 in the distribution direction of the second reflector 320 and the second light source 220. The distribution direction of the second reflector 320 and the second light source 220 can be perpendicular to the central axis direction of the light outlet aperture 120.
[0023] The lighting unit disclosed in this application improves the structure of lighting units related to the relevant technology by setting a reflective component 300, configuring the light source component 200 to include a first light source 210 and a second light source 220, and configuring the reflective component 300 to include a first reflector 310 and a second reflector 320. Furthermore, the first reflector 310 is positioned opposite the first light source 210, and the second reflector 320 is positioned opposite the second light source 220. The first end of the first reflector 310 is connected to the first light source 210, and the second end of the first reflector 310 is spaced apart from the first light source 210 by a first distance. The first end of the second reflector 320 is connected to the second light source 220. The second reflector 320 is connected to the second light source 220, and the second end of the second reflector 320 is spaced apart from the second light source 220 by a second distance. This allows the first reflector 310 to receive the first light ray A emitted by the first light source 210 and reflect at least a portion of the first light ray A out of the second end of the first reflector 310, so that at least a portion of the first light ray A passes through the light exit hole 120 and is projected outside the housing 100, thereby projecting onto the first region 510. The second reflector 320 receives the second light ray B emitted by the second light source 220 and reflects at least a portion of the second light ray B out of the second end of the second reflector 320, so that at least a portion of the second light ray B passes through the light exit hole 120 and is projected outside the housing 100, thereby projecting onto the second region 520.
[0024] Furthermore, by setting the first distance to be greater than the second distance, the first light ray A projected outside the housing 100 is farther away from the housing 100 than the second light ray B projected outside the housing 100, while the second light ray B projected outside the housing 100 is closer to the housing 100 than the first light ray A projected outside the housing 100. This results in the first region 510 being farther away from the housing 100 than the second region 520, and the first region 510 and the second region 520 not overlapping at least partially. This allows the lighting unit to project at least a portion of the first light ray A and at least a portion of the second light ray B onto the first region 510 and the second region 520, which are at different distances from the lighting unit, thereby achieving a richer lighting effect.
[0025] Furthermore, in this structure, the first light source 210, the second light source 220, the first reflector 310, and the second reflector 320 share a housing 100, thereby enabling the emission of both first light A and second light B through a single lighting unit. This improves the compactness of the lighting unit structure compared to existing lighting units that emit two types of light through two lighting units. As a result, the lighting unit of this application can occupy less space to achieve the illumination effect of two types of light compared to the two lighting units of the prior art, thus saving installation space.
[0026] Furthermore, when the first region 510 and the second region 520 do not overlap completely, they can be connected to form a continuous light band, which facilitates a better lighting effect. Optionally, the optical parameters of the first light source 210 and the second light source 220 may not be exactly the same, so that the lighting unit can achieve different lighting effects after projecting at least a portion of the first light ray A and at least a portion of the second light ray B onto the first region 510 and the second region 520 at different distances from the lighting unit, thereby enriching the lighting effect of the lighting unit. For example, the brightness parameters of the first light source 210 and the second light source 220 may be different, so that the first region 510 and the second region 520 can present different brightness, thereby achieving different lighting effects of light and dark. As another example, the color parameters of the first light source 210 and the second light source 220 may be different, so that the first region 510 and the second region 520 can present different colors, thereby achieving different lighting effects of color, that is, achieving a contrasting color effect. This application embodiment does not limit this.
[0027] In specific application scenarios, the lighting unit can be installed on the ceiling via snap-fit, threaded connection, or other methods. In this case, the central axis of the light-emitting aperture 120 can be parallel to the vertical direction, and the distribution directions of the first region 510 and the second region 520 can be parallel to the vertical direction. The lighting unit can project at least a portion of the first light beam A and at least a portion of the second light beam B vertically onto the first region 510 and the second region 520 at different distances from the lighting unit. Specifically, the light-receiving surface 500 can be a wall surface, the first region 510 can be an area on the wall relatively far from the lighting unit, and the second region 520 can be an area on the wall relatively close to the lighting unit. In this case, the lighting unit can be a wall washer light.
[0028] In a further technical solution, the housing 100 may have a connected bottom wall 101 and a first side wall 102. The light-emitting hole 120 may be opposite to the bottom wall 101. The first light source 210 may be connected to the second light source 220 and may be evenly disposed on the first side wall 102 to facilitate the installation of the first light source 210 and the second light source 220. The first reflector 310 may be connected to the second reflector 320. The connection direction of the first reflector 310 and the second reflector 320 may be parallel to the first side wall 102 and perpendicular to the penetration direction of the light-emitting hole 120, so that the first reflector 310 and the second reflector 320 are respectively opposite to the first light source 210 and the second light source 220. This structure can more easily realize the installation of the first light source 210, the second light source 220, the first reflector 310 and the second reflector 320 in the inner cavity 110, thereby reducing the complexity of installation and improving installation efficiency.
[0029] Specifically, the first light source 210 and the second light source 220 can be connected to the first sidewall 102 by means of bonding, threaded connection, etc. Of course, the first light source 210 and the second light source 220 can also be connected to the bottom wall 101 by means of bonding, threaded connection, etc. The first reflector 310 and the second reflector 320 can be connected by means of bonding, threaded connection, integral molding, etc., and the first reflector 310 and the second reflector 320 can be connected to the bottom wall 101 or the second sidewall 103 described below by means of bonding, threaded connection, etc. The embodiments of this application do not limit this.
[0030] Furthermore, in this case, the connection direction of the first reflector 310 and the second reflector 320 can be parallel to the light receiving surface 500, that is, the first sidewall 102 can be parallel to the light receiving surface 500 and the first sidewall 102 can be opposite to the light receiving surface 500.
[0031] When the lighting unit is mounted on the ceiling, the central axis of the light-emitting aperture 120 can be parallel to the vertical direction, and the distribution directions of the first region 510 and the second region 520 can be parallel to the vertical direction. The lighting unit can project at least a portion of the first light ray A and at least a portion of the second light ray B vertically onto the first region 510 and the second region 520, which are at different distances from the lighting unit. Specifically, the light-receiving surface 500 can be a wall surface, the first region 510 can be an area on the wall that is relatively far from the lighting unit, and the second region 520 can be an area on the wall that is relatively close to the lighting unit. In this case, the lighting unit can be a wall washer light.
[0032] In one embodiment, the reflective assembly 300 may further include a first reflector 330, which may be disposed between the first reflector 310 and the second reflector 320. The first reflector 330 is used to reflect at least a portion of the first ray A back to the first reflector 310 and to reflect at least a portion of the second ray B back to the second reflector 320. Specifically, the first reflector 330 may be a specular reflector, and the first reflector 330 may be connected to the first reflector 310 and the second reflector 320 respectively by means of snap-fit, adhesive, etc. The embodiments of this application do not impose any limitations on this.
[0033] In the specific working process, the first reflector 330 can reflect the first ray A received from the first reflector 310 back to the first reflector 310, and also reflect the first ray A directly emitted by the first light source 210 back to the first reflector 310; at the same time, the first reflector 330 can reflect the second ray B received from the second reflector 320 back to the second reflector 320, and also reflect the second ray B directly emitted by the second light source 220 back to the second reflector 320, thereby minimizing the possibility of the first ray A reaching the second reflector 320 and the second ray B reaching the first reflector 310, and further minimizing the possibility of the first ray A being reflected to the second area 520 and the second ray B being reflected to the first area 510, so as to minimize the impact on the lighting effect.
[0034] In an optional technical solution, the reflective assembly 300 may further include a second reflective element 340 and a third reflective element 350, both of which are opposite to the first reflective element 330. That is, the second reflective element 340 and the third reflective element 350 may be opposite to the first reflective element 330 respectively. The second reflective element 340 may be disposed on the side of the first reflective element 310 away from the second reflective element 320, and the third reflective element 350 may be disposed on the side of the second reflective element 320 away from the first reflective element 310. That is, the second reflective element 340 and the third reflective element 350 may be disposed on opposite sides of the first reflective element 330. The second reflective element 340, the first reflective element 330 and the third reflective element 350 may be distributed along the connection direction of the first reflective element 310 and the second reflective element 320. That is, the distribution direction of the second reflective element 340, the first reflective element 330 and the third reflective element 350 may be parallel to the first sidewall 102. Optionally, the first reflector 330, the second reflector 340, and the third reflector 350 can all be perpendicular to their distribution direction, wherein the first reflector 330, the second reflector 340, and the third reflector 350 can each be a plate-shaped reflective structure.
[0035] In the specific operation, the second reflector 340 is used to reflect at least a portion of the first ray A back to the first reflector 310, and the third reflector 350 is used to reflect at least a portion of the second ray B back to the second reflector 320. Specifically, the second reflector 340 can reflect the first ray A received from the first reflector 310 back to the first reflector 310, and also reflects the first ray A directly emitted by the first light source 210 back to the first reflector 310. Simultaneously, the third reflector 350 can reflect the second ray B received from the second reflector 320 back to the second reflector 320, and also reflects the second ray B directly emitted by the second light source 220 back to the second reflector 320. This minimizes the possibility that at least a portion of the first ray A and at least a portion of the second ray B will be projected onto the inner wall of the housing 100, causing them to be easily absorbed by the inner wall of the housing 100 and thus affecting the lighting effect.
[0036] Specifically, the second reflector 340 and the third reflector 350 can both be mirror reflectors. The second reflector 340 and the third reflector 350 can be connected to the first reflector 310 and the second reflector 320 respectively by snap-fitting, bonding or other means. Of course, the first reflector 330, the second reflector 340, the third reflector 350, the first reflector 310 and the second reflector 320 can also be an integral structure. The embodiments of this application do not limit this.
[0037] Furthermore, in this case, the first end of the second reflector 340 facing the light-emitting hole 120, the second end of the first reflector 310, and the first end of the first reflector 330 facing the light-emitting hole 120 can form a first light-emitting port 301, and the first end of the third reflector 350 facing the light-emitting hole 120, the second end of the second reflector 320, and the first end of the first reflector 330 can form a second light-emitting port 302. The first light-emitting port 301 and the second light-emitting port 302 can be opposite to the light-emitting hole 120 respectively. The first light-emitting port 301 and the second light-emitting port 302 can be distributed along the connection direction of the first reflector 310 and the second reflector 320, that is, the distribution direction of the first light-emitting port 301 and the second light-emitting port 302 can be parallel to the first sidewall 102, and the distribution direction of the first light-emitting port 301 and the second light-emitting port 302 can be perpendicular to the distribution direction of the first reflector 310 and the first light source 210.
[0038] Since the first distance between the second end of the first reflector 310 and the first light source 210 is greater than the second distance between the second end of the second reflector 320 and the second light source 220, the size of the first light outlet 301 in the distribution direction of the first reflector 310 and the first light source 210 can be greater than the size of the second light outlet 302 in the distribution direction of the first reflector 310 and the first light source 210. That is, the first light outlet 301 can protrude from the second light outlet 302 in the direction away from the first light source 210. This makes the first light ray A projected outside the housing 100 farther away from the housing 100 than the second light ray B projected outside the housing 100, and the second light ray B projected outside the housing 100 closer to the housing 100 than the first light ray A projected outside the housing 100. As a result, the first region 510 is farther away from the housing 100 than the second region 520, and thus the first region 510 and the second region 520 do not overlap at least partially.
[0039] In the specific working process, the first reflector 310 can reflect at least a portion of the received first light ray A through the first light outlet 301 and out of the second end of the first reflector 310, and the second reflector 320 can reflect at least a portion of the received second light ray B through the second light outlet 302 and out of the second end of the second reflector 320.
[0040] In the embodiments disclosed in this application, the housing 100 may have a bottom wall 101, a first side wall 102, and a second side wall 103. The first side wall 102 and the second side wall 103 may be opposite to each other and may be connected to the bottom wall 101 respectively. The light-emitting hole 120 may be opposite to the bottom wall 101. The second light source 220 may be disposed on the first side wall 102, and the first light source 210 may be disposed between the second light source 220 and the second side wall 103, that is, the first light source 210 may be disposed on the side of the second light source 220 away from the second side wall 103. The second reflector 320 may be disposed between the first light source 210 and the second side wall 103, that is, the first reflector 310 may be disposed on the side of the first light source 210 away from the second side wall 103.
[0041] In this structure, the distribution direction of the first reflector 310 and the second reflector 320 can be perpendicular to the first sidewall 102, thereby enabling the first reflector 310 and the second reflector 320 to conveniently reflect at least a portion of the first light ray A and at least a portion of the second light ray B to the first region 510 and the second region 520, respectively. Specifically, the second light source 220 can be connected to the first sidewall 102 by means of threaded connection, snap-fit, adhesive bonding, etc., and can also be connected to the bottom wall 101 by means of threaded connection, snap-fit, etc. The second reflector 320 can be connected to the bottom wall 101 by means of threaded connection, snap-fit, etc., and the embodiments of this application do not limit this.
[0042] Furthermore, in this case, the first reflector 310 may have a first light-emitting port 301 opposite to the light-emitting hole 120, and the second reflector 320 may have a second light-emitting port 302 opposite to the light-emitting hole 120. The distribution direction of the first light-emitting port 301 and the second light-emitting port 302 may be perpendicular to the first sidewall 102. The first light-emitting port 301 may be located on the side of the second light-emitting port 302 away from the second sidewall 103, so that the first light ray A projected outside the housing 100 can be farther away from the housing 100 than the second light ray B projected outside the housing 100, and the second light ray B projected outside the housing 100 can be closer to the housing 100 than the first light ray A projected outside the housing 100.
[0043] In a preferred embodiment, the first reflector 310 may have a first reflective surface 311, which may be distributed on the side of the first reflector 310 facing the first light source 210. The first reflector 310 is used to reflect at least a portion of the first light ray A. A plurality of first light mixing grooves 312 may be provided on the first reflective surface 311, extending from the first end of the first reflector 310 to the second end. This allows for more uniform light mixing through the multiple first light mixing grooves 312, resulting in more uniform brightness, color, etc., of the at least portion of the first light ray A reflected by the first reflector 310, thereby improving the lighting effect of the lighting unit.
[0044] Furthermore, the second reflector 320 may have a second reflective surface 321, which may be distributed on the side of the second reflector 320 facing the second light source 220. The second reflective surface 321 is used to reflect at least a portion of the second light ray B. The second reflective surface 321 may be provided with a plurality of second light mixing grooves 322, and a plurality of first light mixing grooves 312 may extend from the first end of the second reflector 320 to the second end of the second reflector 320. This allows for more uniform light mixing through the plurality of second light mixing grooves 322, making the brightness, color, etc., of at least a portion of the second light ray B reflected by the second reflector 320 more uniform, thereby improving the lighting effect of the lighting unit.
[0045] In an optional technical solution, the first reflector 310 may have a first reflective surface 311, and the second reflector 320 may have a second reflective surface 321. The first reflective surface 311 may be a curved surface, and / or the second reflective surface 321 may be a curved surface. Specifically, the first reflective surface 311 may bulge in a direction away from the first light source 210, and the second reflective surface 321 may bulge in a direction away from the second light source 220.
[0046] Based on this, in one embodiment, the first reflecting surface 311 can be a curved surface so as to reflect at least a portion of the first light ray A into a parallel or widely divergent beam, thereby enabling at least a portion of the first light ray A to be reflected to a wider area, which is beneficial to increasing the illumination range of the first light source 210.
[0047] In another embodiment, the second reflecting surface 321 may be a curved surface to reflect at least a portion of the second light ray B into a parallel or widely divergent beam, thereby enabling at least a portion of the second light ray B to be reflected to a wider area, which is beneficial to increasing the illumination range of the second light source 220.
[0048] In other embodiments, the first reflecting surface 311 can be a curved surface, and the second reflecting surface 321 can be a curved surface, so as to reflect at least a portion of the first light ray A into a parallel or widely divergent beam, thereby enabling at least a portion of the first light ray A to be reflected to a wider area, which is beneficial to increasing the illumination range of the first light source 210. At the same time, it is also beneficial to reflect at least a portion of the second light ray B into a parallel or widely divergent beam, thereby enabling at least a portion of the second light ray B to be reflected to a wider area, which is beneficial to increasing the illumination range of the second light source 220, and thus beneficial to increasing the illumination range of the lighting unit.
[0049] Furthermore, when both the first reflecting surface 311 and the second reflecting surface 321 are curved surfaces, the first reflecting surface 311 may have a first curvature and the second reflecting surface 321 may have a second curvature. The first curvature may be less than the second curvature, thereby allowing the second end of the first reflecting element 310 to be relatively farther away from the first light source 210 and the second end of the second reflecting element 320 to be relatively closer to the second light source 220, so that the first distance may be greater than the second distance.
[0050] In a further technical solution, the first reflector 310 may have a first reflective surface 311, and the second reflector 320 may have a second reflective surface 321. The first reflective surface 311 may be an inclined surface, and / or the second reflective surface 321 may be an inclined surface. Specifically, the first reflective surface 311 may be inclined in a direction away from the first light source 210, that is, the distance between the first reflective surface 311 and the first light source 210 may increase from a direction away from the light emission aperture 120 to a direction closer to the light emission aperture 120. The second reflective surface 321 may be inclined in a direction away from the second light source 220, that is, the distance between the second reflective surface 321 and the second light source 220 may increase from a direction away from the light emission aperture 120 to a direction closer to the light emission aperture 120.
[0051] Accordingly, in one embodiment, the first reflective surface 311 can be an inclined surface, which is easy to implement and helps reduce manufacturing costs. In another embodiment, the second reflective surface 321 can be an inclined surface, which is easy to implement and helps reduce manufacturing costs. In other embodiments, both the first reflective surface 311 and the second reflective surface 321 can be inclined surfaces, thereby more effectively reducing manufacturing difficulty and thus more effectively reducing manufacturing costs.
[0052] When both the first reflecting surface 311 and the second reflecting surface 321 are inclined surfaces, the first reflecting surface 311 may have a first slope and the second reflecting surface 321 may have a second slope. The first slope may be less than the second slope so that the second end of the first reflecting element 310 can be relatively farther away from the first light source 210, and the second end of the second reflecting element 320 can be relatively closer to the second light source 220, so that the first distance can be greater than the second distance.
[0053] Preferably, the housing 100 may include a plurality of heat sinks 130, which may be distributed outside the inner cavity 110. Specifically, the first light source 210 and the second light source 220 generate heat during operation and easily transfer the heat to the housing 100. This structure increases the contact area between the housing 100 and the air in the external environment of the inner cavity 110 through the plurality of heat sinks 130, which is beneficial to improving the heat dissipation effect of the housing and thus improving the heat dissipation efficiency of the lighting unit, thereby enabling timely heat dissipation. Optionally, the plurality of heat sinks 130 may be distributed evenly and at intervals outside the inner cavity 110 to further improve the heat dissipation efficiency.
[0054] Furthermore, the lighting unit may also include a connector 410 and a light-transmitting plate 420. The light-transmitting plate 420 may be disposed outside the inner cavity 110 and may cover the end face of the light-emitting hole 120 facing outward from the inner cavity 110. The connector 410 may be arranged around the light-emitting hole 120 and may be connected to the housing 100 by means of snap-fit, threaded connection, adhesive, etc., to press the light-transmitting plate 420 to the end face of the light-emitting hole 120 facing outward from the inner cavity 110, thereby fixing the light-transmitting plate 420. This structure can minimize the risk of dust, moisture, etc., entering the inner cavity 110 through the light-emitting hole 120 and easily affecting the working environment of the inner cavity 110. Specifically, the light-transmitting plate 420 may be light-transmitting plastic or light-transmitting glass; the specific type of light-transmitting plate 420 is not limited in this embodiment.
[0055] Based on the lighting unit disclosed in the embodiments of this application, the embodiments of this application further disclose a lighting fixture, which includes the lighting unit 001 described in any of the above embodiments. For example... Figures 1 to 2As shown, when there are multiple lighting units 001, the multiple lighting units 001 are interconnected, which helps to further enrich the lighting effect of the lighting fixture. Specifically, the multiple lighting units 001 can be interconnected by means of snap-fit, threaded connection, etc., and the embodiments of this application do not limit this.
[0056] There are various ways to distribute the multiple lighting units 001. In one embodiment, such as... Figure 1 As shown, multiple lighting units 001 can be arranged in a single row. Of course, in other embodiments, such as... Figure 2 As shown, multiple lighting units 001 can also be distributed in an array.
