[0002] This application claims priority to Chinese Patent Application No. 202411546307.1, filed on October 31, 2024, entitled "Lighting Fixture", and to Chinese Patent Application No. 202422656530.3, filed on October 31, 2024, entitled "Lighting Fixture", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of lighting technology, and more particularly to a luminaire. Background Technology

[0004] Ceiling lights, as an important component of modern home lighting, have gained popularity among consumers for their minimalist design and space-saving features. As consumers increasingly demand higher quality and better experiences in home lighting, more and more consumers prefer ultra-thin and transparent lighting fixtures.

[0005] Existing ceiling lights often employ a surface-emitting structure. This design fixes the lighting components to the base of the fixture, and the light is emitted through a diffuser plate beneath the base. However, this traditional design has several drawbacks. First, the integration of the lighting components with the base increases the overall thickness of the fixture, making it appear bulky and affecting the aesthetics and simplicity of the interior space. Furthermore, while this direct downward light emission provides sufficient illumination, it can also produce strong light reflections on the reflective surface below. These untreated rays may enter the eyes directly or indirectly after reflection, causing glare. Glare not only affects visual comfort but can also have long-term effects on eye health. When reading, working, or relaxing, glare can cause eye fatigue, blurred vision, and even headaches, significantly reducing the comfort and user experience of the lighting environment.

[0006] In view of this, it is indeed necessary to provide a lighting fixture to solve the above problems. Summary of the Invention

[0007] The purpose of this application is to provide a simple, thin, and glare-free lamp.

[0008] To achieve the above objectives, this application provides a lighting fixture, including a housing and a first lighting component and a second lighting component disposed within the housing;

[0009] The first lighting assembly includes a first light guide and a first light source module disposed around the first light guide. The first light guide includes a light-incident surface facing the first light source module and a first light-out surface adjacent to the light-incident surface. The first light guide is configured to receive a first light emitted by the first light source module through the light-incident surface and guide the first light along a first direction through the first light-out surface.

[0010] The second lighting assembly extends at least beyond the first lighting assembly in a direction away from the mounting base, and includes a second light source module and a light emitting element disposed relative to the second light source module. The light emitting element is configured to receive a second light emitted by the second light source module and emit at least a portion of the second light along a second direction intersecting the first direction.

[0011] Optionally, the first light guide may also include a second light-emitting surface disposed opposite to the first light-emitting surface and facing the mounting base.

[0012] Optionally, the housing includes a mounting wall facing the mounting base, a side wall connected to the mounting wall and extending away from the mounting wall, and an extension wall disposed on the side wall, the extension wall dividing the housing into a first mounting space and a second mounting space; wherein, a first lighting component is disposed in the first mounting space, a first light source module is disposed on the side wall, and a first light guide is disposed between the mounting wall and the extension wall; a second lighting component is disposed in the second mounting space; and a second light source module is disposed on the extension wall or the side wall.

[0013] Optionally, the second light source module is disposed on the side of the extension wall facing the second installation space, and the light-emitting component includes a blocking part and a light-transmitting part, wherein the blocking part is disposed relative to the second light source module in such a way as to partially block the second light.

[0014] Optionally, the shielding part is provided with a stepped part, which includes an abutting surface and a protrusion extending away from the light-transmitting part relative to the abutting surface. The extended wall is abutted and installed on the abutting surface, and the protrusion abuts against the first light guide.

[0015] Optionally, the housing also includes a bottom wall, which is located at the end of the side wall away from the mounting wall, and a limiting wall is provided on the side of the bottom wall away from the side wall; one end of the light-emitting element abuts against the first light guide element, and the other end abuts against the bottom wall and is limited by the limiting wall.

[0016] Optionally, the second lighting assembly further includes a second light guide located on the light output path of the second light source module, including a light-inlet surface facing the second light source module and a third light-outlet surface facing the light-outlet.

[0017] Optionally, the first light guide is a nano light guide plate.

[0018] Optionally, the first light guide is integrally formed, or the first light guide includes at least two parts, which are spliced ​​together to form the first light guide.

[0019] Compared with the prior art, the technical solutions of the embodiments of this application have the following beneficial effects:

[0020] The lamp of this application emits a first light source module surrounding a first light guide, emitting a first light beam from the side. This beam, after passing through the first light guide, forms a surface-emitting light beam, guided from a first direction. This allows the thickness of the first lighting component to be controlled within 5mm to 10mm, and the overall lamp thickness within 30mm to 40mm, resulting in a simple and lightweight lamp. Furthermore, the side of the first light guide receives the first light beam emitted by the first light source module, allowing the first light source module to be partially obscured by the light guide, creating a concealed lighting effect that is aesthetically pleasing and effectively avoids glare caused by direct light, improving the comfort of the lighting environment and the user experience. By intersecting the second light beam emitted by the second lighting component with the first light beam emitted by the first lighting component, the light intensity in the first direction is increased, improving the lighting effect. Additionally, the shadow area of ​​the lamp is effectively reduced, resulting in more uniform lighting and improved lighting comfort. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be noted that, in order to avoid obscuring this application with unnecessary details, only the structures and / or processing steps closely related to the solution of this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0036] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Please refer to Figures 1 to 9, which show a luminaire 100 according to Embodiment 1 of this application. The luminaire 100 includes a housing 10 and a first lighting component 20 and a second lighting component 30 disposed within the housing 10. The housing 10 is used to mount the luminaire 100 to a mounting base (e.g., a ceiling). The second lighting component 30 extends at least beyond the first lighting component 20 in a direction away from the mounting base. Optionally, the first lighting component 20 is the main lighting component, and the second lighting component 30 is an ambient lighting component. This arrangement is designed to meet the diverse lighting environment needs of users.

[0038] A first direction is defined as the direction away from the mounting base, and a second direction is defined as the direction intersecting the first direction. As shown in Figure 4, the first direction includes, but is not limited to, the Y direction, which is vertically downward along the height direction of the luminaire 100, and the second direction includes, but is not limited to, the X direction, which is perpendicular to the Y direction. At least a portion of the first light rays emitted by the first lighting component 20 can be emitted along the first direction (or approximately parallel to the Y direction). At least a portion of the second light rays emitted by the second lighting component 30 can be emitted along the second direction, which intersects the first direction (or approximately parallel to the X direction). This arrangement ensures that the second light rays emitted by the second lighting component 30 intersect with the first light rays emitted by the first lighting component 20, thereby increasing the light intensity in the first direction and improving the lighting effect. Furthermore, it effectively reduces the shadow area of ​​the luminaire 100, making the lighting more uniform and improving lighting comfort.

[0039] Please refer to Figures 1 to 6. The housing 10 includes a mounting wall 11 facing the mounting base, a side wall 12 connected to the mounting wall 11 and extending away from the mounting wall 11, an extension wall 14 disposed on the side wall 12 and in the same extending direction as the mounting wall 11, and a bottom wall 13 disposed at one end of the side wall 12 away from the mounting wall 11. The mounting wall 11, the side wall 12, and the bottom wall 13 enclose a light source mounting space for mounting the first lighting component 20 and the second lighting component 30.

[0040] In this embodiment, the extension wall 14 is located at a non-end position of the side wall 12, dividing the housing 10 into a first mounting space 16 for mounting the first lighting component 20 and a second mounting space 17 for mounting the second lighting component 30. That is, in this example, the first lighting component 20 is located in the first mounting space 16 above the housing 10, and the second lighting component 30 is located in the second mounting space 17 below the first mounting space 16. In other words, the second lighting component 30 is located on the side of the first lighting component 20 facing away from the mounting base and extends beyond the first lighting component 20 in the direction facing away from the mounting base. This arrangement allows for efficient use of the space in the lamp 100, resulting in a compact structure and reduced volume. Furthermore, the extension wall 14 effectively isolates the first lighting component 20 and the second lighting component 30, preventing the first light emitted from the first light source module 21 in the first lighting component 20 from directly entering the second mounting space 17 and interfering with the light output of the second lighting component 30. This also prevents the second light emitted by the second light source module 31 in the second lighting component 30 from directly entering the first installation space 16 and interfering with the light output of the first lighting component 20.

[0041] Of course, in other embodiments, the second lighting component 30 may also be disposed around the first lighting component 20 and extend beyond the first lighting component 20 in a direction away from the mounting base. That is, the second lighting component 30 may also be disposed on the side of the first lighting component 20 and disposed around the first lighting component 20, but the second lighting component 30 extends at least partially below the first lighting component 20, so that the second light emitted by the second lighting component 30 can at least partially intersect with the first light emitted by the first lighting component 20, thereby improving the light intensity and light uniformity of a portion of the luminaire 100.

[0042] Please refer to Figures 4 and 5. In this embodiment, the housing 10 has an annular structure. The mounting wall 11 also has an annular structure. Of course, in other embodiments, the housing 10 can also have other structures. For example, the housing 10 can be a square structure, etc., in which case the mounting wall 11 is also a square structure.

[0043] Referring to Figures 4 and 5, in this embodiment, the mounting wall 11 has a centrally located, annular second light-emitting port. By providing the second light-emitting port, a portion of the first light emitted by the first lighting component 20 can be projected from the second light-emitting port onto the mounting base (e.g., the ceiling), thereby illuminating the mounting base and enhancing the ambiance of the luminaire 100. In other embodiments, the second light-emitting port on the mounting wall 11 may be located in a non-central position, or it may be annular, square, or any other arbitrary structure. Alternatively, in an optional embodiment, the mounting wall 11 may not have a second light-emitting port. This application does not limit this.

[0044] Please refer to Figures 4 and 5. A first light-emitting port is provided on the extension wall 14. By providing the first light-emitting port, a portion of the first light emitted by the first lighting component 20 can be projected from the first light-emitting port into a direction away from the mounting base (i.e., the first direction), thereby illuminating the environment. That is, the first light-emitting port is the main light-emitting port.

[0045] In some embodiments, the extension wall 14 is disposed close to the mounting wall 11. This arrangement makes the first mounting space 16 smaller than the second mounting space 17, thereby making better use of the internal space of the luminaire 100 and making the luminaire 100 more compact overall. In other embodiments, the extension wall 14 may be disposed away from the mounting wall 11, making the first mounting space 16 larger than the second mounting space 17.

[0046] In some embodiments, the extension length of the extension wall 14 exceeds the extension length of the mounting wall 11 in the direction away from the side wall 12. This arrangement facilitates the mounting of the second lighting assembly 30 on the side of the extension wall 14 facing the second mounting space 17.

[0047] In this embodiment, the housing 10 is a one-piece molded structure. This design simplifies the manufacturing process and reduces costs. Furthermore, the one-piece molded housing 10 allows for a smoother and more seamless appearance, enhancing the aesthetics of the lamp 100, reducing connection points and seams, and improving the durability of the lamp 100. Of course, in other embodiments, the housing 10 may be formed by combining multiple structures. This application does not limit this.

[0048] Referring to Figure 4, the first lighting component 20 is disposed in the first mounting space 16, including a first light source module 21 and a first light guide 22. The first light guide 22 is configured to receive the first light emitted by the first light source module 21 and guide at least a portion of the first light along a first direction. The first light guide 22 is disposed between the mounting wall 11 and the extension wall 14, and the first light source module 21 is disposed on the side wall 12 and surrounds the first light guide 22. That is, in this embodiment, the first lighting component 20 is a side-emitting lighting component. The first light source module 21 emits the first light from the side towards the first light guide 22, and after being acted upon by the first light guide 22, the line light emission is converted into a surface light emission form. With this configuration, the thickness of the first lighting component 20 can be controlled to 5mm to 10mm, and the overall thickness of the lamp 100 can be controlled to 30mm to 40mm, making the lamp 100 simple and thin, achieving ultra-thin design. Furthermore, the lamp 100 does not require a separate chassis for mounting the first light source module 21, thus saving materials and reducing costs. In addition, the first light source module 21 emits the first light beam from the side towards the first light guide 22, allowing the first light source module 21 to be shielded by the first light guide 22, thereby creating a concealed lighting effect of "light emanating but not visible," which is aesthetically pleasing and effectively avoids glare problems caused by direct light, improving the comfort of the lighting environment and the user experience.

[0049] The first light source module 21 includes a first light source substrate and a first light-emitting element disposed on the first light source substrate. The first light-emitting element surrounds the outside of the first light guide 22 and emits light towards the side of the first light guide 22. That is, through the first light guide 22, the linear first light emitted by the side-emitting first light source module 21 is transformed into surface light, avoiding glare caused by direct light. Moreover, since the first light source module 21 emits light from the side, the user cannot see the first light source module 21 visually, but can still feel the illumination light, thus achieving a hidden lighting effect of "light emanating but not visible," which is aesthetically pleasing.

[0050] In this embodiment, the first light-emitting element includes light-emitting elements of at least two colors. Each color of light-emitting element can be controlled independently. This arrangement allows the first lighting assembly 20 to simulate light at different times of day in nature, thereby creating a feeling of being in nature in the room and improving living comfort. For example, by controlling the light-emitting color and brightness of the light-emitting elements, the first lighting assembly 20 can realize different scene images. Please refer to Figures 7 and 8, for example, a red sunset scene, a blue sky scene, and a scene of contrasting colors, etc.

[0051] In some embodiments, the light-emitting element is a double-dish LED. That is, two light-emitting chips are contained in one package unit. The colors of these two light-emitting chips can be the same or different. Preferably, two light-emitting chips of different colors are contained in one package unit. The first light-emitting element includes at least two different colored light-emitting elements. For example, the first light-emitting element includes a first light-emitting element and a second light-emitting element. The first light-emitting element includes two different colored light-emitting chips (e.g., it can include green and blue light-emitting chips), and the second light-emitting element includes two other different colored light-emitting chips (e.g., it can be yellow and red light-emitting chips). The first light-emitting element and the second light-emitting element are staggered on the first light source substrate. The two light-emitting chips in two adjacent first light-emitting elements / second light-emitting elements can be arranged in reverse, etc., which is not limited in this application. By setting the light-emitting element as a double-dish LED, multiple color temperatures can be achieved in one light-emitting element, improving the comfort and functionality of lighting, increasing design flexibility, making the same lamp 100 suitable for a variety of different environments and occasions, and improving the energy efficiency and lifespan of the lamp 100.

[0052] In some embodiments, the light-emitting element is a single-packaged chip. The first light-emitting element includes light-emitting elements of two or more colors. The light-emitting units of multiple colors are arranged sequentially and cyclically along the extension direction of the first light source substrate. By mixing the light emitted by the light-emitting units of multiple colors, the colors of sunlight at different times of day can be simulated, simulating the different color effects of sunlight from morning to dusk, resulting in higher color reproduction of the lamp 100 and improving the user experience. Preferably, the first light-emitting element includes light-emitting elements of four colors. These four colors of light-emitting elements may include: red light-emitting unit, blue light-emitting unit, yellow light-emitting unit, and green light-emitting unit. Of course, in other embodiments, the colors of the light-emitting units may be other colors, or the light-emitting units may include only two colors, or may include two or more colors such as three or five. This application does not limit this.

[0053] In some embodiments, the first light-emitting element may also include only one color of light-emitting element. For example, the first light-emitting element is a white light-emitting element, in which case the first light-emitting element is mainly used for illumination.

[0054] Furthermore, each color of the light-emitting element can be controlled independently. By controlling the brightness and color of the light-emitting elements in the first light-emitting element, different time periods of brightness and darkness can be achieved, enabling color changes in different scenes.

[0055] The first light guide 22 includes a light-incident surface 221 facing the first light source module 21 and a first light-exiting surface 223 adjacent to the light-incident surface 221. That is, the side of the first light guide 22 is the light-incident surface 221, and the bottom of the first light guide 22 away from the mounting base is the first light-exiting surface 223. The first light guide 22 is configured to receive the first light emitted by the first light source module 21 via the light-incident surface 221, and guide the first light along a first direction via the first light-exiting surface 223, thereby achieving illumination.

[0056] Please refer to Figures 4 to 6. In this embodiment, the first light guide 22 further includes a second light-emitting surface 222 disposed opposite to the first light-emitting surface 223 and facing the mounting base. That is, in this embodiment, the light-emitting surface of the first light guide 22 includes a first light-emitting surface 223 and a second light-emitting surface 222 disposed opposite to each other. The first light-emitting surface 223 corresponds to the first light-emitting port on the extension wall 14. The second light-emitting surface 222 corresponds to the second light-emitting port on the mounting wall 11.

[0057] In other words, the first light-emitting surface 223 is located below the first light guide 22 (on the side facing away from the mounting base), configured to receive the first light emitted by the first light source module 21 and guide the first light along a first direction. That is, the first light-emitting surface 223 serves as the main light-emitting surface, emitting light downwards towards the mounting base, responsible for providing the main lighting light and ensuring that the basic lighting needs of the space are met. The second light-emitting surface 222 is located above the first light guide 22, configured to receive the first light emitted by the first light source module 21 and emit the first light in a direction away from the first direction. That is, the second light-emitting surface 222 serves as an auxiliary light-emitting surface, emitting light towards the mounting base, which can illuminate the ceiling, create ambiance, and supplement lighting. By setting the first light-emitting surface 223 and the second light-emitting surface 222, the luminaire 100 of this application can emit light from both the top and bottom surfaces, improving the overall transparency of the light-emitting surfaces of the luminaire 100 and enhancing the aesthetics of the luminaire 100. By adjusting the angle and intensity of the first light rays on the first light-emitting surface 223 and the second light-emitting surface 222, different light and shadow effects can be created in space, increasing the sense of layering and three-dimensionality.

[0058] In some embodiments, only the first light-emitting surface 223 may emit light, while the second light-emitting surface 222 may not emit light. For example, a reflective element may be provided or a reflective layer may be coated on the second light-emitting surface 222, so that the first light emitted by the first light-emitting element is emitted only through the first light-emitting surface 223 along the first direction, thereby improving the brightness of the spatial lighting.

[0059] Furthermore, the first light guide 22 is a nano-light guide plate. The nano-light guide plate incorporates nanoscale particles into a transparent optical-grade material. Because these particles are nanoscale, they are invisible to the human eye, making the entire assembly transparent. This ensures that both the first light-emitting surface 223 and the second light-emitting surface 222 of the first lighting assembly 20 are transparent. Additionally, by using a nano-light guide plate, the line light emitted by the first light-emitting element can be uniformly converted into a surface light source, eliminating the need for a diffuser or light-diffusing plate, reducing the number of parts in the luminaire 100, and lowering costs.

[0060] Referring to Figure 9 and in conjunction with Figure 3, in this embodiment, since the first light guide 22 is a nano-light guide plate, and the surface of the nano-light guide plate is flat and smooth, the first light-emitting surface 223 has a mirror-like or mirror-like reflective effect. That is, the first light-emitting surface 223 is entirely a mirror-like or mirror-like imaging area 40. At least part of the second light emitted by the second light source module 31 is projected onto the imaging area 40, and then a virtual image is formed on the imaging area 40 (as shown in Figure 9, a simulation effect diagram from the second viewpoint B). By reflecting off the first light-emitting surface 223 and forming a mirror image of the second light source module 31 on the imaging area 40, the effect of the window shadow formed on the window when one side of the window is illuminated by sunlight is simulated, making it appear deep and transparent to the human eye.

[0061] In some embodiments, the first light-emitting surface 223 of the first light guide 22 may not be entirely a mirror or mirror-like structure, but may only contain a partially mirror or mirror-like structure (i.e., the imaging area 40). For example, a mirror material may be applied to the first light-emitting surface 223 near the second illumination component 30 to make it the imaging area 40.

[0062] In other embodiments, a transparent plate may be disposed below the first light guide 22, so that the first light emitting surface 223 includes a mirror-like or mirror-like imaging area 40. A portion of the second light emitted by the second light source module 31 is projected onto the imaging area 40, and then a virtual image is formed on the imaging area 40.

[0063] In this embodiment, the nano-light guide plate is integrally molded. This design simplifies the production process, reduces production costs, and extends service life.

[0064] Referring to Figures 4 to 7, in this embodiment, the second lighting component 30 is disposed in the second mounting space 17. That is, the second lighting component 30 is disposed below the first light guide 22 and extends in a direction away from the mounting base. In other words, the second lighting component 30 is at least partially located below the first lighting component 20.

[0065] The second lighting assembly 30 includes a second light source module 31 and a light emitting element 33. The light emitting element 33 is configured to receive a second light emitted by the second lighting assembly 30, so as to allow at least a portion of the second light to be emitted along a second direction intersecting the first direction.

[0066] In this embodiment, the second light source module 31 is disposed on the extension wall 14. As shown in FIG4, the second light source module 31 includes a second light source substrate and a second light-emitting element disposed on the second light source substrate. The second light source substrate is disposed on the side of the extension wall 14 facing the second mounting space 17. The second light-emitting element is disposed on the second light source substrate and emits second light rays in a direction away from the mounting wall 11. At least a portion of the second light rays are emitted towards the inner side of the side wall 12 after passing through the light-emitting element 33. That is, the second illumination component 30 is a side-emitting illumination. The second light rays emitted by the second illumination component 30 along the second direction intersect with the first light rays emitted by the first illumination component 20 along the first direction. For example, a portion of the second light rays emitted by the second illumination component 30 can illuminate the light-emitting element 33, and another portion can be projected onto the imaging area 40 to form a virtual image.

[0067] In some embodiments, by controlling the illumination state of the second light source module 31, a sunlight effect can be created on the light-emitting element 33, illuminating the window sill and visually forming a translucent window effect. For example, some of the second light source modules 31 can be illuminated, thus forming a light-emitting area on the light-emitting element 33. When the second light source modules 31 are turned off, a non-light-emitting area is formed on the light-emitting element 33. Furthermore, a light / shadow transition zone can be formed between the light-emitting and non-light-emitting areas. The light / shadow transition zone serves as a boundary between light and shadow between the light-emitting and non-light-emitting areas. It can be a continuously changing area from bright to dark, or it can be a distinct dividing line. This arrangement allows the luminaire 100 to simulate the effect of natural light entering the room through a window, bringing richer light and shadow variations to the interior space, and creating a unique light and shadow effect by the window. This design allows people to feel the illusion of a window even in a windowless space, increasing the sense of openness and nature in the room.

[0068] In other embodiments, the second light source module 31 may also be disposed on the sidewall 12. That is, the second light source substrate is disposed around the sidewall 12, the second light-emitting element emits second light directly in a direction away from the sidewall 12, and the second light is emitted at least partially along a second direction intersecting the first direction after passing through the light-emitting element 33.

[0069] The second light-emitting element includes light-emitting elements of at least two colors. Optionally, the light-emitting elements in the second light-emitting element can also be dual-dish LEDs or single-packaged chips. The arrangement of the light-emitting elements in the second light-emitting element can be referred to the description in the first light-emitting element, and will not be repeated here.

[0070] Furthermore, each color of the light-emitting element in the second light-emitting component can be independently controlled. By controlling the color and brightness of the light-emitting elements in the second light-emitting component, a variety of unique light source effects can be customized on the light-emitting component 33, including color transition areas and / or light / shadow transition areas. This provides users with great flexibility and creative space. Moreover, by precisely controlling the color and brightness of each light-emitting element, smooth color transition areas and / or light / shadow transition areas can be formed on the light-emitting component 33. This transition effect makes color changes more natural and smooth, avoiding abrupt color transitions.

[0071] Please refer to Figures 4 and 6. The second lighting assembly 30 also includes a second light guide 32. The second light guide 32 is located in the light output path of the second light source module 31. The second light guide 32 is configured to receive the second light emitted by the second light source module 31 and transmit the second light to the light output member 33, so as to allow at least a portion of the second light to be emitted along the second direction via the light output member 33.

[0072] The second light guide 32 includes a light-inlet surface facing the second light source module 31 and a third light-outlet surface facing the light-outlet component 33. In this embodiment, the second light guide 32 extends vertically and is located below the second light source module 31, and is arranged around the light-outlet component 33. The upper light-inlet surface of the second light guide 32 corresponds to the second light source module 31, and its lower end abuts against the bottom wall 13. The second light emitted from the second light source module 31 enters the second light guide 32 through the light-inlet surface, and after illuminating the light-outlet component 33 from the third light-outlet surface, it is emitted along a second direction. By setting the second light guide 32, the light of the second lighting assembly 30 can be evenly distributed, providing a more comfortable visual experience.

[0073] Furthermore, to improve the light emission effect of the second lighting component 30, a reflective surface can be provided on the side of the second light guide 32 opposite to the light emitting component 33. That is, by coating with a high-reflectivity paint or laser dotting, the light illuminating the reflective surface can be reflected to the third light emitting surface for emission. Of course, in other embodiments, reflective elements can also be provided on the second light guide 32 and / or the side wall 12, or a reflective layer can be provided on the side wall 12. This application does not limit this.

[0074] In some embodiments, at least a portion of the sidewall 12 is translucent. The second light emitted by the second light source module 31 can also exit to the outside of the sidewall 12 after passing at least partly through the second light guide 32.

[0075] In some embodiments, the second light guide 32 is at least partially exposed on the bottom wall 13, so that the second light emitted by the second light source module 31 can also be emitted in a direction away from the mounting base after passing through the second light guide 32.

[0076] The light-emitting element 33 is disposed on the side of the second light guide 32 away from the side wall 12. One end of the light-emitting element 33 abuts against the first light guide 22, and the other end abuts against the bottom wall 13. That is, the light-emitting element 33 can enclose the second mounting space 17, thereby preventing the second light source module 31 from being directly seen and improving the aesthetics of the lamp 100.

[0077] Further, referring to Figure 5, a limiting wall 15 is provided on the side of the bottom wall 13 of the housing 10 away from the side wall 12. The light-emitting element 33 is disposed on the side of the limiting wall 15 facing the side wall 12 and is limited and fixed by the limiting wall 15 to fix the light-emitting element 33 to the housing 10.

[0078] Please refer to Figures 4, 6, and 7. The light-emitting element 33 is a diffuser mask, formed by two-color injection molding. That is, the light-emitting element 33 includes a blocking part 331 and a light-transmitting part 332. The blocking part 331 is made of an opaque material and is positioned close to the second light source module 31, configured to block the second light source module 31 or at least partially block the light emitted by the second light source module 31. The light-transmitting part 332 is made of a diffuser material and is configured to emit light. For example, the blocking part 331 can be white, which can block the graininess of the second light-emitting element, prevent the second light-emitting element from being seen, and achieve a hidden lighting effect where light is emitted but not seen, improving the aesthetics of the lamp 100. Furthermore, the white blocking part 331 can also reflect light, thereby improving the lighting effect of the second lighting assembly 30. The light-transmitting part 332 can be made of a transparent or semi-transparent diffuser material to achieve a uniform light effect, making the emitted light of the second lighting assembly 30 more uniform, less dazzling, and preventing glare.

[0079] Further, referring to Figure 6, the shielding portion 331 is provided with a stepped portion 333. The stepped portion 333 includes an abutting surface 3331 and a protruding portion 3332 that protrudes from the abutting surface 3331 in a direction away from the light-transmitting portion 332. The extension wall 14 is abutted and installed on the abutting surface 3331. The protruding portion 3332 abuts against the first light guide 22. With this arrangement, the extension wall 14 can be shielded by the light-emitting member 33, and the extension wall 14 is not visible from the outside, thereby improving the aesthetics of the lamp 100. Furthermore, one end of the light-emitting member 33 abuts against the extension wall 14 through the abutting surface 3331, and the other end abuts against the bottom wall 13, so that the light-emitting member 33 can be fixedly mounted on the housing 10 from both the top and bottom directions.

[0080] Furthermore, the blocking portion 331 protrudes from the light-transmitting portion 332 on the side facing the second light guide 32, so that there is a gap between the third light-emitting surface of the second light guide 32 and the light-emitting element 33, thereby increasing the optical path distance and making the light emission more uniform. Of course, in other embodiments, the blocking portion 331 and the light-transmitting portion 332 on the side facing the second light guide 32 can also be flush. This application does not limit this.

[0081] Furthermore, the thickness of the second lighting component 30 can be controlled between 25mm and 30mm, thereby allowing the overall luminaire 100 to be controlled between 30mm and 40mm, making the overall luminaire 100 thinner and lighter.

[0082] Figure 8 shows a simulation of the luminaire 100 from the first viewpoint A shown in Figure 3. In Figure 8, the first light source module 21 emits blue light, making the first light guide 22 appear entirely blue. The second light source module 31 emits white light, making the light emitting element 33 appear entirely white. The white second lighting component 30 surrounds the blue first lighting component 20. The overall luminaire 100 is aesthetically pleasing and has a sense of transparency.

[0083] Figure 9 shows a simulation of the luminaire 100 from the second viewpoint B shown in Figure 3. In Figure 9, the first light source module 21 emits blue light, making the first light guide 22 appear entirely blue. The second light source module 31 emits white light. From the second viewpoint B, the light-emitting component 33 is partly a white light-emitting area and partly a black non-light-emitting area. Furthermore, there is a light / shadow transition zone between the light-emitting and non-light-emitting areas. The white second lighting component 30 projects a virtual image onto the imaging area 40 of the blue first light guide 22. The overall luminaire 100 is aesthetically pleasing, creating a blue sky effect with a sense of depth and transparency. It allows one to realistically experience the effect of a blue sky and sunlight illuminating the window sill indoors.

[0084] Please refer to Figures 10 to 12, which show the lighting fixture 100 according to Embodiment 2 of this application. In this embodiment, the lighting fixture 100 also includes a housing 10 and a first lighting component 20 and a second lighting component 30 disposed within the housing 10. Furthermore, the second lighting component 30 extends beyond the first lighting component 20 in a direction away from the mounting base.

[0085] The structure and connection relationship of the various components in the lamp 100 in Embodiment 2 are basically the same as those in Embodiment 1, except that the structure of the first light guide 22 is different in Embodiment 2. Therefore, the following description only focuses on the differences between Embodiment 2 and Embodiment 1, and the similarities are not repeated here.

[0086] In this embodiment, the first light guide 22 comprises at least two parts, which are joined together to form the first light guide 22. This arrangement ensures that the light from the two parts of the first light guide 22 does not interfere with each other, resulting in purer light output.

[0087] Referring to Figure 11, in some embodiments, the first light guide 22 is divided into a first light guide portion 224 and a second light guide portion 225 by an S-shaped curve. The color of the first light-emitting element in the first light guide portion 224 can be set to blue, while the color of the first light-emitting element in the second light guide portion 225 can be set to red, thus making the first light guide portion 224 appear blue and the second light guide portion 225 appear red. Furthermore, the boundary between blue and red is clear and does not intersect, improving the aesthetics of the lamp 100.

[0088] Referring to Figure 12, in some embodiments, the first light guide 22 is divided into a first light guide portion 224 and a second light guide portion 225 by an S-shaped curve. The color temperature of the first light-emitting element in the first light guide portion 224 is set to 2700K, while the color temperature of the first light-emitting element in the second light guide portion 225 is set to 5700K, resulting in different color temperatures for the first light guide portion 224 and the second light guide portion 225.

[0089] Of course, in other embodiments, the first light-emitting elements corresponding to the first light guide portion 224 and the second light guide portion 225 can be set to other colors. Alternatively, the first light guide element 22 can be divided into other shapes as needed to present different visual effects. This application does not limit this.

[0090] In summary, the lamp 100 of this application, by having the first light source module 21 surround the outer periphery of the first light guide 22 and emit first light rays from the side towards the first light guide 22, and then forming surface light emission after being acted upon by the first light guide 22, and guided from the first direction, allows the thickness of the first lighting component 20 to be controlled within 5mm to 10mm, and the overall thickness of the lamp to be controlled within 30mm to 40mm, making the lamp 100 simple and thin overall. Furthermore, the side of the first light guide 22 receives the first light rays emitted by the first light source module 21, allowing the first light source module 21 to be shielded by the first light guide 22, thus creating a "light emission without light exposure" concealed lighting effect, which is aesthetically pleasing and effectively avoids glare problems caused by direct light, improving the comfort of the lighting environment and the user experience. By intersecting the second light rays emitted by the second lighting component 30 with the first light rays emitted by the first lighting component 20, the light intensity in the first direction can be increased, improving the lighting effect. Furthermore, it can effectively reduce the shadow area of ​​the lamp by 100%, making the lighting more uniform and improving lighting comfort.

[0091] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application 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 this application without departing from the spirit and scope of the technical solutions of this application.
