Abstract
Description
Technical Field
[0001] This application belongs to the field of lighting fixture design technology, and specifically relates to a lighting fixture. Background Technology
[0002] Lighting fixtures are widely used in various locations, such as ceiling lights. In specific applications, lighting fixtures are typically mounted on a surface (such as a ceiling), and they usually emit light in a direction away from the surface to achieve illumination. However, this structure causes the surface to easily fall into shadow, resulting in a darker surface and a brighter space away from it. This leads to a harsh light transition in the application scenario, which can easily affect the lighting effect. Utility Model Content
[0003] This utility model discloses a lighting fixture to alleviate the problem of poor lighting effect caused by the harsh light transition in lighting scenarios in related technologies.
[0004] To alleviate the above-mentioned technical problems, this utility model provides the following technical solution: This application discloses a lighting fixture, which includes a housing, a first light source, a second light source, a first light-transmitting cover, a second light-transmitting cover, and a light-guiding structure; The lighting fixture is used to be mounted to the mounting surface through the housing. The first light-transmitting cover and the second light-transmitting cover are both located on the side of the housing away from the mounting surface, and the second light-transmitting cover is arranged around the first light-transmitting cover. The first light-transmitting cover and the housing together form a first accommodating space, and the second light-transmitting cover and the housing together form a second accommodating space. The first light source is disposed in the first accommodating space, and the second light source and the light guide structure are both disposed in the second accommodating space. The light guide structure is opposite to the second light source and is used to receive and scatter the second light emitted by the second light source so that at least part of the second light is projected onto the mounting surface through the second light-transmitting cover.
[0005] The technical solution adopted in this utility model can achieve the following technical effects: The lighting fixture disclosed in this application improves the structure of lighting fixtures related to the relevant technology by setting a second light-transmitting cover around a first light-transmitting cover, and by setting both the second light source and the light guide structure in a second accommodating space formed by the second light-transmitting cover and the housing, and by setting the light guide structure opposite to the second light source, so that the light guide structure can receive and scatter the second light emitted by the second light source, thereby allowing at least part of the second light to be projected onto the mounting surface through the second light-transmitting cover to illuminate the mounting surface. This alleviates the problem of harsh light transition between the mounting surface and the space away from the mounting surface due to the mounting surface being too dark, making the light transition in the lighting scene more natural, and thus improving the lighting effect of the lighting fixture.

[0011] Please refer to Figures 1 to 6 This application discloses a lighting fixture, which includes a housing 100, a first light source 210, a second light source 220, a first light-transmitting cover 310, a second light-transmitting cover 320, and a light guide structure 400.
[0012] The housing 100 is the basic component of the lighting fixture, providing mounting positions for other components of the lighting fixture. The first light source 210, the second light source 220, the first light-transmitting cover 310, the second light-transmitting cover 320, and the light guide structure 400 are all located within the housing 100. Furthermore, the lighting fixture is mounted to the mounting surface 500 via the housing 100. The housing 100 can be connected to the mounting surface 500 through snap-fit, magnetic connection, or connector connection, thereby enabling the lighting fixture to be mounted on the mounting surface 500. The mounting surface 500 can be a ceiling; however, this embodiment does not limit the specific type of the mounting surface 500. Additionally, the housing 100 also forms functional spaces or structures, such as a first accommodating space A and a second accommodating space B.
[0013] Both the first light-transmitting cover 310 and the second light-transmitting cover 320 serve to protect the internal structure of the lighting fixture and to control light distribution. Both the first light-transmitting cover 310 and the second light-transmitting cover 320 are located on the side of the housing 100 opposite to the mounting surface 500. The first light-transmitting cover 310 and the second light-transmitting cover 320 can be connected to the housing 100 via snap-fit, connectors, or other means. The second light-transmitting cover 320 surrounds the first light-transmitting cover 310 and can be located around the first light-transmitting cover 310. Specifically, both the first light-transmitting cover 310 and the second light-transmitting cover 320 can be transparent. The materials of the first light-transmitting cover 310 and the second light-transmitting cover 320 can be PMMA (Polymethyl Methacrylate), PS (Polystyrene), etc., and this application embodiment does not impose any limitations on these materials.
[0014] The first light source 210 and the second light source 220 are both core components for achieving illumination in the lighting fixture. The light guide structure 400 is the core component for scattering the second light ray C emitted by the second light source 220 in the lighting fixture. The first light-transmitting cover 310 and the housing 100 together form a first receiving space A, and the second light-transmitting cover 320 and the housing 100 together form a second receiving space B. The second receiving space B can surround the periphery of the first receiving space A, that is, the second receiving space B can be an annular space. The first light source 210 is disposed in the first receiving space A. The second light source 220 and the light guide structure 400 are both disposed in the second receiving space B. The second light source 220 and the light guide structure 400 can both surround the first light source 210. The light guide structure 400 is opposite to the second light source 220 so that the light guide structure 400 can receive the second light ray C emitted by the second light source 220.
[0015] In the specific operation, the first light emitted by the first light source 210 can pass through the first light-transmitting cover 310 and be projected outside the first receiving space A, thereby illuminating the space on the side of the first light-transmitting cover 310 facing away from the mounting surface 500 to achieve a lighting effect. The light guide structure 400 is used to receive and scatter the second light C emitted by the second light source 220, so that at least part of the second light C is projected onto the mounting surface 500 through the second light-transmitting cover 320, thereby illuminating the mounting surface 500.
[0016] Specifically, the light guide structure 400 can achieve scattering through the diffusing agent or diffusion layer described later, thereby breaking up the received second light rays C, so that at least a portion of the second light rays C can exit the second light-transmitting cover 320 from different directions. The second light rays C emitted from the second light-transmitting cover 320 can be directed towards a space away from the mounting surface 500, or towards the mounting surface 500. The portion of the second light rays C directed towards the mounting surface 500 can be projected onto the mounting surface 500 along the periphery of the lighting fixture, thereby forming light spots distributed around the lighting fixture on the mounting surface 500, and further forming a ring-shaped lighting area around the lighting fixture on the mounting surface 500. When the mounting surface 500 is a ceiling, this structure can achieve a ceiling-washing effect.
[0017] The lighting fixture disclosed in this application improves the structure of lighting fixtures related to the relevant technology by setting a second light-transmitting cover 320 around a first light-transmitting cover 310, and by setting both the second light source 220 and the light guide structure 400 in the second accommodating space B formed by the second light-transmitting cover 320 and the housing 100, and by setting the light guide structure 400 opposite to the second light source 220, so that the light guide structure 400 can receive and scatter the second light C emitted by the second light source 220, so that at least part of the second light C can be projected onto the mounting surface 500 through the second light-transmitting cover 320 to illuminate the mounting surface 500. This can alleviate the problem of the mounting surface 500 being too dark, which causes a harsh light transition between the mounting surface 500 and the space away from the mounting surface 500, making the light transition in the lighting scene more natural, and thus improving the lighting effect of the lighting fixture.
[0018] In one embodiment, the first light source 210 may include a first circuit board 211 and a plurality of first light source bodies 212. The plurality of first light source bodies 212 may be fixed to the side of the first circuit board 211 facing the first light-transmitting cover 310 by means of welding, bonding, snap-fitting, etc. The first circuit board 211 may be connected to the housing 100 by means of bonding, snap-fitting, threaded connection, etc. Specifically, the first circuit board 211 may be a printed circuit board or a rigid-flex board, and the first light source body 212 may be an LED. This application embodiment does not limit this.
[0019] Optionally, the second light source 220 may include a second circuit board 221 and a plurality of second light source bodies 222. The plurality of second light source bodies 222 may be fixed to one side of the light-guiding structure 400 of the second circuit board 221 by means of welding, bonding, snap-fitting, etc. The second circuit board 221 may be connected to the housing 100 by means of bonding, snap-fitting, threaded connection, etc. Specifically, the second circuit board 221 may be a ring-shaped circuit board distributed around the first light-transmitting cover 310. The plurality of second light source bodies 222 may be distributed around the first light-transmitting cover 310. The second circuit board 221 may be a printed circuit board or a rigid-flex board. The second light source body 222 may be an LED. This application embodiment does not limit this.
[0020] In a further technical solution, the second light-transmitting cover 320 may protrude from the first light-transmitting cover 310 in a direction away from the housing 100. The outer surface of the second light-transmitting cover 320 may have a first light-emitting surface 321, a second light-emitting surface 322, and a third light-emitting surface 323 connected in sequence. The first light-emitting surface 321 and the third light-emitting surface 323 may be located on the side of the light guide structure 400 away from the first light-transmitting cover 310 and the side of the light guide structure 400 facing the first light-transmitting cover 310, respectively. The second light-emitting surface 322 may be located on the side of the light guide structure 400 away from the second light source 220. This allows the second light C to be projected from the first light-emitting surface 321, the second light-emitting surface 322, and the third light-emitting surface 323 to the outside of the second receiving space B via the light guide structure 400.
[0021] In the specific working process, the light guide structure 400 is used to scatter the second light ray C. That is, the light guide structure 400 can change the direction of the second light ray C, so that the second light ray C is projected to different directions through the light guide structure 400. Thus, a part of the second light ray C can be projected to the mounting surface 500 and the first light-transmitting cover 310 through the first light-emitting surface 321 and the third light-emitting surface 323, respectively, and another part of the second light ray C can be projected to the outside of the second receiving space B through the second light-emitting surface 322 in a direction away from the second light source 220.
[0022] In this structure, the second light ray C projected onto the mounting surface 500 illuminates the mounting surface 500, and the second light ray C projected onto the first light-transmitting cover 310 causes the third light-emitting surface 323 to form an image on the first light-transmitting cover 310, thereby increasing the visual depth of the lighting fixture and improving its transparency, which is beneficial to enhancing the user experience. It should be noted that the second light ray C emitted from the first light-emitting surface 321 can be directed towards a space away from the mounting surface 500, or towards the mounting surface 500, thus illuminating the mounting surface 500; the second light ray C emitted from the third light-emitting surface 323 can be directed towards a space away from the first light-transmitting cover 310, or towards the first light-transmitting cover 310, so that the third light-emitting surface 323 can form an image on the first light-transmitting cover 310, thus forming an image; the depth direction of the visual depth can be parallel to the central axis direction of the first light-transmitting cover 310.
[0023] Furthermore, the second light ray C, projected from the second light-emitting surface 322 in a direction away from the second light source 220 and extending beyond the second receiving space B, can illuminate the space on the side of the second light-transmitting cover 320 facing away from the mounting surface 500. Meanwhile, the first light ray can pass through the first light-transmitting cover 310 and project beyond the first receiving space A, thus illuminating the space on the side of the first light-transmitting cover 310 facing away from the mounting surface 500. This allows the lighting fixture to better illuminate the space on the side facing away from the mounting surface 500, facilitating better lighting. Simultaneously, the second light ray C projected onto the first light-transmitting cover 310 allows for a more natural transition of light between the first and second light-transmitting covers 310 and 320, minimizing the possibility of excessive darkness between them, which could negatively impact visual effects and lead to a poor user experience.
[0024] In the optional technical solution, the second light-emitting surface 322 may be provided with a plurality of first light-mixing grooves 324. The plurality of first light-mixing grooves 324 may be distributed around the first light-transmitting cover 310, so that the second light C emitted from the second light-emitting surface 322 can be uniformly emitted, which helps to alleviate glare and thus can minimize the user's ability to observe the second light source 220 in the second accommodating space B through the second light-emitting surface 322, thereby improving the user experience.
[0025] Optionally, a plurality of first light mixing grooves 324 may be evenly distributed around the second light-transmitting cover 320, and the plurality of first light mixing grooves 324 may all extend around the central axis of the first light-transmitting cover 310. That is, the first light mixing grooves 324 may be annular grooves, and the plurality of first light mixing grooves 324 may be evenly spaced apart, wherein the central axis of the plurality of first light mixing grooves 324 may coincide with the central axis of the first light-transmitting cover 310.
[0026] This structure enables the second light ray C emitted from the second light-emitting surface 322 to be more uniform, thereby more effectively alleviating the situation where users can easily observe the second light source 220 in the second accommodating space B through the second light-emitting surface 322, thus better mitigating the glare problem and further improving the user experience.
[0027] Of course, in other embodiments, the extending directions of the plurality of first light-mixing grooves 324 may all be perpendicular to the central axis direction of the first light-transmitting cover 310, that is, the plurality of first light-mixing grooves 324 may all extend radially along the first light-transmitting cover 310, and the plurality of first light-mixing grooves 324 may be distributed around the central axis direction of the first light-transmitting cover 310, so as to reduce manufacturing difficulty. Specifically, in this case, the plurality of first light-mixing grooves 324 may all be strip grooves.
[0028] In one embodiment, the light guide structure 400 can be a light guide ring, which can be arranged around the first light-transmitting cover 310. The light guide ring and the inner wall of the second light-transmitting cover 320 can be spaced apart, so that the second light ray C has a free diffusion distance after leaving the light guide ring, which further homogenizes the light intensity distribution of the second light ray C, thereby achieving a softer light source effect and improving the user experience. At the same time, this structure has relatively good mechanical strength, which helps to improve the stability of the light guide structure 400. Specifically, the light guide ring can be a semi-transparent structure, and the light guide ring can contain a light diffusing agent. The material of the light guide ring can be PMMA (Polymethyl Methacrylate), PS (Polystyrene), etc., and the embodiments of this application do not limit this.
[0029] In another embodiment, the light guide structure 400 can be a light guide cover, which can be arranged around the first light-transmitting cover 310. The inner walls of the light guide cover and the second light-transmitting cover 320 can be spaced apart, so that the second light ray C has a free diffusion distance after leaving the light guide cover, which further homogenizes the light intensity distribution of the second light ray C, thereby achieving a softer light source effect and improving the user experience. At the same time, this structure has a small weight, which is conducive to the lightweight design of lighting fixtures and cost savings. The light guide cover can be a semi-transparent structure, and the light guide cover can contain a light diffusing agent. The material of the light guide cover can be PMMA (Polymethyl Methacrylate), PS (Polystyrene), etc., and the embodiments of this application do not limit this.
[0030] Optionally, the second light-transmitting cover 320 may include multiple limiting protrusions, which may be spaced apart on the inner wall of the second light-transmitting cover 320. The light guide structure 400 may be supported on the multiple limiting protrusions respectively, spaced apart from the inner wall of the second light-transmitting cover 320, thereby facilitating the installation of the light guide structure 400 and making it easier to space the light guide structure 400 from the inner wall of the second light-transmitting cover 320. Of course, in other embodiments, the light guide structure 400 may be connected to the housing 100 by means of snap-fit, threaded connection, etc., thereby spaced apart from the inner wall of the second light-transmitting cover 320.
[0031] In a further technical solution, the outer surface of the light guide structure 400 facing away from the second light source 220 can be provided with multiple second light mixing grooves 410. These multiple second light mixing grooves 410 can be distributed around the first light-transmitting cover 310, thereby enabling the second light ray C emitted uniformly from the outer surface of the light guide structure 400 facing away from the second light source 220. This structure allows the second light ray C emitted from the outer surface of the light guide structure 400 facing away from the second light source 220 to be projected more uniformly outside the second accommodating space B through the second light-transmitting surface 322 when the second light-transmitting cover 320 has a second light-emitting surface 322. This minimizes the possibility of the user observing the second light source 220 within the second accommodating space B through the second light-emitting surface 322 and the light guide structure 400, thus alleviating glare and improving the user experience.
[0032] Furthermore, multiple second light-mixing grooves 410 can be evenly distributed around the first light-transmitting cover 310, and the extending direction of the second light-mixing grooves 410 can be perpendicular to the central axis direction of the first light-transmitting cover 310. That is, multiple second light-mixing grooves 410 can be evenly spaced around the first light-transmitting cover 310, and the second light-mixing grooves 410 can extend radially along the first light-transmitting cover 310. Specifically, in this case, the second light-mixing grooves 410 can be strip-shaped grooves. This structure enables the second light C emitted from the outer surface of the light guide structure 400 away from the second light source 220 to be more uniform. At the same time, this structure can better alleviate glare, thereby more effectively reducing the situation where users can easily observe the second light source 220 in the second accommodating space B through the second light-emitting surface 322 and the light guide structure 400, which is beneficial to further improving the user experience.
[0033] Furthermore, with multiple first light-mixing grooves 324 provided on the second light-emitting surface 322, and all of the multiple first light-mixing grooves 324 extending around the central axis of the first light-transmitting cover 310, each of the multiple first light-mixing grooves 324 can be annular grooves and can be distributed around the first light-transmitting cover 310. Simultaneously, since the extension direction of each of the multiple second light-mixing grooves 410 can be perpendicular to the central axis of the first light-transmitting cover 310, each of the multiple second light-mixing grooves 410 can be a strip groove. This allows the extension direction of each of the multiple second light-mixing grooves 410 to be perpendicular to the central axis of the first light-transmitting cover 310. The extension directions of the first light mixing grooves 324 intersect, thereby increasing the path complexity of the second light ray C projected from the light guide structure 400 and the second light emitting surface 322 to the outside of the second accommodating space B. This is beneficial to improving the light mixing effect, and thus enables the second light ray C projected from the second light emitting surface 322 to the outside of the second accommodating space B to be mixed more effectively. This can better alleviate glare and further reduce the risk that users may observe the second light source 220 in the second accommodating space B through the second light emitting surface 322 and the light guide structure 400.
[0034] Of course, in other embodiments, the plurality of second light mixing grooves 410 may also extend around the central axis of the first light-transmitting cover 310, that is, the plurality of second light mixing grooves 410 may all be annular grooves, and this application embodiment does not limit this.
[0035] In the embodiments disclosed in this application, the light guide structure 400 can be a light guide layer, which can cover the inner wall of the second light-transmitting cover 320, thereby facilitating the reduction of the overall weight of the lighting fixture and promoting a lighter design. Specifically, the light guide layer can be a first white ink layer, which can be printed on the inner wall of the second light-transmitting cover 320 to cover it.
[0036] Optionally, the light guide layer and the second light-transmitting cover 320 can be an integral structure, which simplifies the assembly process and reduces the installation difficulty. In this case, the light guide layer can also be a first etched layer or a first laser mesh layer. In addition, the light guide layer can also be a semi-transparent diffusion layer. The light guide layer and the second light-transmitting cover 320 can be formed by integral molding.
[0037] In one embodiment, the housing 100 may include a connected frame 110 and a base 120, with the frame 110 surrounding the base 120. A first light-transmitting cover 310 and a second light-transmitting cover 320 may both be connected to the frame 110. The first light-transmitting cover 310, the base 120, and the frame 110 together form a first receiving space A, and the second light-transmitting cover 320 and the frame 110 together form a second receiving space B. This structure helps reduce the manufacturing difficulty of the housing 100, thereby reducing manufacturing costs.
[0038] Specifically, the frame 110 and the base 120 can be connected by means of threaded connection, snap-fit, etc. The first light-transmitting cover 310 and the second light-transmitting cover 320 can both be connected to the frame 110 by means of snap-fit, threaded connection, etc. The first light source 210 can be connected to the base 120 by means of threaded connection, adhesive, etc., thereby realizing the installation of the first light source 210 in the first accommodating space A. The second light source 220 can be connected to the frame 110 by means of threaded connection, adhesive, etc., thereby realizing the installation of the second light source 220 in the second accommodating space B. The embodiments of this application do not limit this.
[0039] In a further technical solution, the enclosure 110 may include an outer frame 111, an inner frame 112, and a connector 113. Both the outer frame 111 and the inner frame 112 can be connected to the connector 113. The outer frame 111 and the inner frame 112 can be connected to the connector 113 by welding, snap-fitting, or other methods to reduce manufacturing difficulty. Alternatively, the outer frame 111, inner frame 112, and connector 113 can be integrally formed for easier assembly. The inner frame 112 can be located inside the outer frame 111. The second light-transmitting cover 320 can be connected to the outer frame 111, and the second light-transmitting cover 320 can press a portion of the structure of the first light-transmitting cover 310 to the inner frame 112 to fix the first light-transmitting cover 310. This avoids the need for additional connecting structures to fix the first light-transmitting cover 310, thus fully utilizing the second light-transmitting cover 320, which helps save costs and improves structural compactness.
[0040] The base 120 and the second light source 220 can be connected to opposite sides of the connector 113 by means of threaded connection, snap-fit, etc., to avoid interference between the base 120 and the second light source 220, so as to facilitate the installation of the base 120 and the second light source 220. The first light source 210 can be provided on the base 120, and the first light source 210 can be connected to the base 120 by means of threaded connection, snap-fit, etc.
[0041] Meanwhile, the inner frame 112, connector 113, base 120 and first light-transmitting cover 310 can together form a first accommodating space A, and the outer frame 111, inner frame 112, connector 113 and second light-transmitting cover 320 can together form a second accommodating space B, thereby making it easier to form the first accommodating space A and the second accommodating space B, and making the second accommodating space B surround the first accommodating space A.
[0042] In other embodiments, the outer frame 111, inner frame 112, connector 113 and base 120 can be an integral structure, that is, the housing 100 can be an integral structure, which helps to reduce the complexity of assembly and facilitates installation.
[0043] In a preferred embodiment, the first light-transmitting cover 310 may further include a diffusion layer 311. The diffusion layer 311 may be distributed on the side of the first light-transmitting cover 310 facing the first light source 210. The diffusion layer 311 is used to receive and diffuse the first light emitted by the first light source 210, so that the diffused first light passes through the first light-transmitting cover 310 and is projected outside the first receiving space A, thereby achieving an illumination effect. This structure can minimize the user's ability to observe the first light source 210 through the first light-transmitting cover 310, which is beneficial to improving the user experience. Specifically, the diffusion layer 311 may be any one or a combination of the second white ink layer, the second etched layer, and the second laser mesh layer. The specific type of the diffusion layer 311 is not limited in this embodiment.
[0044] To enrich the lighting effect of the lighting fixtures, the diffusion layer 311 may have multiple hollow areas, which may be pentagonal hollow areas, triangular hollow areas, etc. The specific type of hollow areas is not limited in the embodiments of this application.
[0045] In an optional technical solution, the second light-transmitting cover 320 may protrude from the first light-transmitting cover 310 in a direction away from the housing 100. The side of the first light-transmitting cover 310 away from the first light source 210 is configured as a fourth light-emitting surface 312, which can be a reflective surface to reflect the second light ray C projected onto the fourth light-emitting surface 312. That is, at least a portion of the second light ray C can be projected onto the fourth light-emitting surface 312 via the light guide structure 400 and the second light-transmitting cover 320. The fourth light-emitting surface 312 can reflect the second light ray C projected onto the fourth light-emitting surface 312, thereby enabling the portion of the second light-transmitting cover 320 facing the fourth light-emitting surface 312 to form an image on the first light-transmitting cover 310, thus increasing the visual depth of the lighting fixture and improving its transparency, which is beneficial to improving the user experience.
[0046] For example, the first light-transmitting cover 310 can be a plate-shaped structural component, and the fourth light-emitting surface 312 can be a smooth plane, which facilitates the formation of a more continuous reflection on the first light-transmitting cover 310 and helps to improve the quality of the reflection formed on the first light-transmitting cover 310.
[0047] Furthermore, as a preferred illustration as a non-limiting example, the first light source 210 may include a first brightness parameter, and the second light source 220 may include a second brightness parameter. The first brightness parameter and the second brightness parameter may not be equal, so that there is a difference in brightness between the first light and the second light, thereby facilitating the formation of a reflection on the first light-transmitting cover 310.
[0048] Preferably, the second brightness parameter can be 2 to 3 times the first brightness parameter, so that the part of the second light-transmitting cover 320 facing the fourth light-emitting surface 312 can form a clearer reflection on the first light-transmitting cover 310, which can better increase the visual depth of the lighting fixture, while avoiding excessive differences in illuminance uniformity between side-emitting and surface-emitting light, which would lead to glare caused by an extremely high brightness ratio, thereby destroying the sense of layering and visual comfort of the spatial lighting; in addition, an excessively large second brightness parameter can also easily lead to excessive energy consumption of the second light source 220, and this structure can avoid the above situation.
[0049] The lighting fixtures disclosed in this application can be ceiling lights (such as skylights, skylights, etc.) or decorative lights. This application does not limit the specific type of lighting fixture.

As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.
