AI Technical Summary
Traditional ceiling lights require a large space to mix multiple colors of light, resulting in a less compact design that fails to meet the modern lighting requirements for small and compact fixtures, and also fails to effectively create diverse environmental atmospheres.
The design employs a combination of a beam splitter and a transparent element. The beam splitter is an array of beam splitting lenses with concave and convex surfaces of peaks and troughs. The transparent element is spaced apart from the diffuser. The beam splitter performs beam splitting and total internal reflection of multicolor light within the mixing cavity, while the transparent element performs multiple total internal reflections to achieve light mixing and divergence.
Without increasing the size of the lamp body, it achieves the mixing of multi-color light to create an environmental atmosphere such as blue sky or starry sky, improving visual transparency and user experience.

[0002] This application claims priority to Chinese Patent Application No. 202423094414.3, filed on December 13, 2024, entitled "Lighting Fixture and Lighting Fixture Assembly", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This invention relates to a lamp and lamp assembly, belonging to the field of lighting technology. Background Technology
[0004] Ceiling lights are the most commonly used lighting fixtures in our daily lives, and conventional ceiling lights typically only provide illumination. However, with societal development, people's demands for lighting fixtures have become increasingly diversified. In addition to illumination, people also hope that lighting fixtures can play a greater decorative role in the overall home environment. This decoration is not only reflected in the shape of the light fixture but also in the creation of the lighting atmosphere. Therefore, ceiling lights that simulate the atmosphere of a blue sky or starry sky by mixing multiple colors of light have emerged.
[0005] However, the process of multi-colored light rays being emitted from the LED beads and then mixed in the mixing cavity usually requires a certain amount of space to ensure that the multi-colored light rays intersect in the mixing cavity, which undoubtedly goes against the traditional compact design concept of ceiling lights.
[0006] In view of this, it is indeed necessary to improve traditional lighting fixtures to solve the above problems. Summary of the Invention
[0007] The present invention provides a lamp, comprising: a light-emitting body; a diffuser surrounding the outer periphery of the light-emitting body and in the light-emitting direction of the light-emitting body; and a transparent member surrounding the outer periphery of the diffuser and spaced apart from the diffuser, wherein the transparent member is configured such that light rays are incident on the transparent member through the diffuser and then scattered from its light-emitting surface.
[0008] In one embodiment, the transparent element has a structure that is thin in the middle and thick at both ends.
[0009] In one embodiment, at least a portion of the light rays undergo multiple total internal reflections between the incident and exiting surfaces of the transparent element before exiting from the exiting surface.
[0010] In one embodiment, the gap between the transparent element and the diffuser is a structure that is wide in the middle and narrow at both ends.
[0011] In one embodiment, the light further includes a beam splitter, which is an array beam splitter lens, and the beam splitter's beam splitting surface faces the light emitter. The beam splitting surface is a concave-convex surface with peaks and troughs. The beam splitter is configured to split the multicolor light emitted by the light emitter and then incident it onto the diffuser.
[0012] In one embodiment, the beam splitter further includes an annular frame. The beam splitter includes a first assembly portion and a second assembly portion. The first assembly portion is housed within the annular frame. In the radial direction of the beam splitter, the second assembly portion extends toward the diffuser by a greater length than the first assembly portion extends toward the diffuser, so as to form a boss on the upper surface of the second assembly portion. The boss abuts against the annular frame, and the lower surface of the second assembly portion abuts against the diffuser.
[0013] In one embodiment, the light emitter includes at least two sets of light source components, which are arranged vertically or horizontally. Each set of light source components includes at least two different colored light-emitting units. These at least two different colored light-emitting units are combined with each other and separated by a spacer. Each light-emitting unit has a different color from its adjacent light-emitting unit.
[0014] In one embodiment, the light emitter includes at least four sets of light source components, which are arranged in an array in the vertical and horizontal directions. The light emitter has light source components with the same light emission color in different columns, and in the two closest columns, two light source components with the same light emission color are arranged in an alternating pattern.
[0015] In one embodiment, the axis of the light-emitting surface of the light-emitting body is defined as the optical axis, and in the light-emitting direction perpendicular to the light-emitting body, the optical axis is lower than the center line of the diffuser.
[0016] The present invention provides a lighting assembly, including a driving device and at least two aforementioned lighting fixtures, wherein the driving device is used to control the at least two lighting fixtures to be turned on or off respectively, and the at least two lighting fixtures are of different sizes.

Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] Referring to Figure 1, this invention discloses a lighting assembly 400, including a ceiling assembly 200 and at least two lighting fixtures 100. The ceiling assembly 200 and the at least two lighting fixtures 100 are connected by a plurality of cables 300. The ceiling assembly 200 is used to mount the lighting assembly 400 to a mounting surface. The at least two lighting fixtures 100 are both annular in shape and differ in size and position in the vertical direction, thereby providing different illumination effects.
[0034] The lighting assembly 400 also includes a driving device disposed inside the ceiling assembly 200 to control the opening or closing of at least two lighting fixtures 100 respectively.
[0035] The lamp 100 can create an atmosphere similar to a blue sky or starry sky to provide users with a good experience.
[0036] Specifically, referring to Figures 2 to 6, the lamp 100 includes an annular frame 1, a light-emitting element 2, a beam splitter 3, a diffuser 4, and a transparent element 5. The annular frame 1 includes an upper frame 11 and a lower frame 12 assembled together, forming an assembly area 10 between the upper frame 11 and the lower frame 12. The light-emitting element 2, the beam splitter 3, the diffuser 4, and the transparent element 5 are all sequentially assembled within the assembly area 10. The light emitted by the light-emitting element 2 is emitted after passing through the beam splitter 3, the diffuser 4, and the transparent element 5. Preferably, the assembly area 10 is the outer wall surface of the lower frame 12.
[0037] In this embodiment, the light-emitting element 2 is arranged around the outer periphery of the annular frame 1 and configured to emit light from the side. The light-emitting element 2 can emit multi-colored light towards the outer periphery of the annular frame 1. A mixing cavity 40 is formed between the beam splitter 3 and the diffuser 4. The multi-colored light emitted by the light-emitting element 2 intersects and mixes within the mixing cavity 40 to create the desired environmental atmosphere for the user.
[0038] Since the process of multi-colored light rays from emission to intersection requires a certain amount of space, the overall structure of the lamp 100 is often enlarged when designing the lamp 100, which undoubtedly goes against the traditional concept of small and compact lamp design.
[0039] Therefore, by setting the beam splitter 3, the multi-color light emitted by the light source 2 is split, so that they can intersect and mix in advance, and then be incident on the diffuser 4, so as not to affect the overall size of the lamp 100.
[0040] Please refer to Figure 4. In this embodiment, the upper frame 11 is provided with a receiving groove 110. The receiving groove 110 is recessed away from the lower frame 12, and the lower frame 12, the light-emitting element 2, and the beam splitter 3 are all partially housed within the receiving groove 110. By providing the receiving groove 110, the lamp 100 becomes thinner and lighter.
[0041] Referring to Figures 3 and 4, the beam splitter 3 includes a first assembly portion 32 and a second assembly portion 33. The first assembly portion 32 is housed within the receiving groove 110. In the radial direction of the beam splitter 3, the second assembly portion 33 extends towards the diffuser 4 by a greater length than the first assembly portion 32 extends towards the diffuser 4, forming a boss 331 on the upper surface of the second assembly portion 33. The boss 331 abuts against the upper frame 11, and the lower surface of the second assembly portion 33 abuts against the diffuser 4. In other words, the beam splitter 3 is clamped and positioned within the assembly area 10 by the upper frame 11 and the diffuser 4. The presence of the boss 331 ensures that the beam splitting surface 31 of the beam splitter 3 always faces the light emitter 2 for beam splitting.
[0042] Referring to Figures 3, 12, and 13, preferably, the beam splitter 3 is arranged around the outer periphery of the light emitter 2, and the beam splitting surface 31 of the beam splitter 3 faces the light emitter 2. The beam splitter 3 is preferably an array beam splitting lens, and the beam splitting surface 31 is a concave-convex surface with peaks and troughs. This arrangement can eliminate the graininess of the light while ensuring good beam splitting effect.
[0043] Referring to Figures 7 to 9, the axis of the emitting surface of the light-emitting body 2 is defined as the optical axis 20. In the emitting direction perpendicular to the light-emitting body 2, the optical axis 20 is lower than the center line 41 of the diffuser 4. This arrangement allows most of the light emitted by the light-emitting body 2 to converge in the lower half of the diffuser 4, ensuring that most of the light shines downwards, which is beneficial for downward illumination by the lamp 100. The diffuser 4, surrounding the light-emitting body 2 and the beam splitter 3 and positioned in the light-emitting direction of the light-emitting body 2, serves to homogenize the light.
[0044] Preferably, the optical axis 20 is 1-5 mm lower than the center line 41 of the diffuser 4. According to experiments, the light output effect of the lamp 100 is better within this range.
[0045] The transparent element 5 is arranged around the outer periphery of the diffuser 4 and spaced apart from the diffuser 4. This allows the multicolored light emitted by the light source 2 to undergo total internal reflection within the transparent element 5 after entering it. In other words, a gap 50 exists between the transparent element 5 and the diffuser 4. After the multicolored light emitted by the light source 2 exits from the diffuser 4, at least a portion of the multicolored light enters the transparent element 5 through the gap 50. After undergoing multiple total internal reflections between the light-incident surface and the light-exit surface 51 of the transparent element 5, it exits from the light-exit surface 51 of the transparent element 5. The transparent material of the transparent element 5 makes the light output more transparent, improving the user experience. The gap 50 between the transparent element 5 and the diffuser 4 allows the mixed light to undergo multiple total internal reflections on the inner and outer surfaces of the transparent element 5, increasing the optical path of the mixed light and further improving visual transparency.
[0046] Preferably, the interval 50 has a structure that is wide in the middle and narrow at both ends, that is, the middle interval is wide and the two side intervals are narrow. In this way, the light path for secondary refraction of mixed light can be extended at the middle interval position, thereby increasing visual transparency.
[0047] Specifically, as shown in Figure 14, the light emitted from the transparent component 5 has excellent transparency, which can improve the user experience.
[0048] Preferably, the transparent element 5 is a transparent ring with non-uniform wall thickness. The thickness of the transparent element 5 is greatest in the direction of the optical axis 20 of the light-emitting element 2 and smallest in the direction away from the optical axis 20. Regardless of the direction, the thickness of the transparent element 5 is between 4.5 mm and 16 mm.
[0049] Along the optical axis 20 of the light-emitting body 2, as the angle increases, the thickness of the transparent part 5 decreases from thick to thin and then increases again, so that the transparent part 5 forms a concave lens-like structure that is thin in the middle and thick at both ends, in order to diffuse the light as much as possible and expand the illumination area of the light. Furthermore, the non-uniform thickness change of the transparent part 5, which is thin in the middle and thick at both ends, results in more total internal reflection in the middle position, stronger light emission, and weaker light emission on both sides, thereby increasing visual transparency.
[0050] In this embodiment, the light-emitting element 2 is configured to emit light outwards to create an ambient atmosphere in conjunction with the main light source. In other embodiments, the light-emitting element 2 may emit light inwards to mix with the main light source and create an ambient atmosphere on the main light-emitting surface of the lamp 100.
[0051] Specifically, as shown in Figure 10, in this embodiment, the light-emitting body 2 includes at least two sets of light source components 21, which are arranged vertically or horizontally. Each set of light source components 21 includes a light source plate 211 and light-emitting units 212 disposed on the light source plate 211. The light-emitting units 212 on adjacent sets of light source components 21 are of different colors. In other words, the mixing of multicolor light involves mixing two sets of light source components 21 of different colors.
[0052] When at least two sets of light source components 21 are arranged vertically, the luminaire 100 can be a tower-shaped luminaire or a vertical luminaire that extends straight down from top to bottom. When at least two sets of light source components 21 are arranged vertically, the luminaire 100 can be a strip luminaire or a ring luminaire.
[0053] Each light source assembly 21 includes at least two different colored light-emitting units 212, which are combined with each other and separated by a separator 213. Each light-emitting unit 212 is a different color from its adjacent light-emitting unit 212. Thus, when the colors of the light-emitting units 212 on two adjacent light source assemblies 21 are all different, the light mixing of the two light source assemblies 21 is actually a mixture of four colors, thereby simulating a deeper environmental atmosphere.
[0054] For example, the first group of light source components 21 has light-emitting units A and B, and the second group of light source components 21 has light-emitting units C and D. In this case, the colors of the light-emitting units 212 on the two adjacent groups of light source components 21 are not the same.
[0055] In other embodiments, it is also possible to consider having light-emitting unit A and light-emitting unit B in the first group of light source components 21, and light-emitting unit A and light-emitting unit C in the second group of light source components 21. This can also achieve light mixing, but the simulated environmental atmosphere level is reduced.
[0056] Of course, two or more colors can be mixed, and there are no restrictions on this, as long as the light from adjacent groups of light source components 21 is different.
[0057] Please refer to Figure 11. In another embodiment, the light source 2 includes at least four sets of light source components 21. The at least four sets of light source components 21 are arranged in an array in the vertical and horizontal directions. Each set of light source components 21 includes a light source plate 211 and a light-emitting unit 212 disposed on the light source plate 211. The light-emitting units 212 on adjacent sets of light source components 21 have different colors.
[0058] In this embodiment, only one light-emitting unit 212 is provided on the light source plate 211. Therefore, when it is desired to simulate a deeper environmental atmosphere, at least four sets of light source components 21 need to be arranged in an array. This way, a good light mixing effect can be achieved when the light is mixed between adjacent columns.
[0059] The light-emitting body 2 is provided with light source components 21 with the same light emission color in different columns. In the two columns that are closest to each other, the two light source components 21 with the same light emission color are arranged in an alternating manner.
[0060] For example, the two light source components 21 in the first column have light-emitting units A and B respectively, and the two light source components 21 in the second column have light-emitting units C and A respectively. In order to ensure the light mixing effect, the two light-emitting units A must not be adjacent. Therefore, the two light source components 21 with light-emitting units A must be arranged in an alternating manner.
[0061] Assuming that the two light source components 21 in the first column have light-emitting units A and B respectively, and the two light source components 21 in the second column have light-emitting units C and D respectively, then there are no identical light-emitting units 212 in the two adjacent light source components 21, which allows for a deeper simulation of the environmental atmosphere.
[0062] When the two light source components 21 in the third column each have a light-emitting unit A and a light-emitting unit B, if the two light source components 21 with light-emitting unit A are located in the same row, then A and C will mix, and C and A will mix, severely damaging the light mixing effect. Therefore, in this case, the two light source components 21 with light-emitting unit A need to be arranged in an alternating manner, so that the first row is A and C mixing, C and B mixing, and the second row is B and D mixing, and D and A mixing.
[0063] In summary, the lamp 100 and lamp assembly 400 of the present invention, on the one hand, provide a transparent element 5 on the outer periphery of the diffuser 4, and the transparent element 5 is provided at intervals from the diffuser 4, so that after light passes through the diffuser 4 and enters the transparent element 5, it can be scattered from the light-emitting surface 51 of the transparent element 5, thereby achieving the transparency of human vision.
[0064] On the other hand, by setting a beam splitter 3 between the light emitter 2 and the diffuser 4, and setting a mixing cavity 40 between the beam splitter 3 and the diffuser 4, the multicolor light emitted by the light emitter 2 is split by the beam splitter 3, enters the mixing cavity 40 for mixing, and then enters the diffuser 4 and is emitted to create an ambient atmosphere. In addition, an array beam splitter lens is used as the beam splitter 3, and the beam splitting surface of the beam splitter 3 facing the light emitter 2 is set as a concave-convex surface with peaks and valleys to further enhance the beam splitting effect, so that the multicolor light can intersect and complete the mixing in a small space.
[0065] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
