[0042] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in detail below in combination with the drawings and specific embodiments.

[0043] Please refer to Figure 1 The utility model discloses a lamp assembly 400, including ceiling assembly 200 and at least two lamps 100, the ceiling assembly 200 and at least two lamps 100 are connected through a plurality of cables 300, the ceiling assembly 200 is used to install the lamp assembly 400 to the mounting surface. At least two lamps 100 are annular, and the size is different, and the position in vertical direction is also different, to provide different illumination effect.

[0044] The lamp assembly 400 further includes driving device, the driving device is arranged in the ceiling assembly 200 internally to control the opening or closing of at least two lamps 100 respectively.

[0045] The lamp 100 can create a kind of atmosphere effect of environment such as blue sky or starry sky, to give user good experience.

[0046] Specifically, please combine Figures 2 to 6As shown, the lamp 100 comprises a ring-shaped frame 1, a light emitter 2, a light splitting member 3, a diffusion cover 4 and a transparent member 5. The ring-shaped frame 1 comprises an upper frame 11 and a lower frame 12 assembled with each other, and a fitting area 10 is formed between the upper frame 11 and the lower frame 12. The light emitter 2, the light splitting member 3, the diffusion cover 4 and the transparent member 5 are sequentially fitted in the fitting area 10, and the light emitted by the light emitter 2 is emitted after passing through the light splitting member 3, the diffusion cover 4 and the transparent member 5. Preferably, the fitting area 10 is the outer wall surface of the lower frame 12.

[0047] In the embodiment, the light emitter 2 is arranged around the outer periphery of the ring-shaped frame 1 and is configured to emit light sideways. The light emitter 2 can emit multi-color light towards the outer periphery of the ring-shaped frame 1. A mixing cavity 40 is formed between the light splitting member 3 and the diffusion cover 4, and the multi-color light emitted by the light emitter 2 intersects and mixes in the mixing cavity 40 to create the environment atmosphere required by the user.

[0048] Since the process from emission to intersection of the multi-color light requires a certain space, the overall structure of the lamp 100 is often enlarged when designing the lamp 100, which undoubtedly deviates from the existing design concept of small and compact lamps.

[0049] Therefore, by arranging the light splitting member 3, the multi-color light emitted by the light emitter 2 is split and intersects and mixes in advance, and then is incident on the diffusion cover 4, so that the overall size of the lamp 100 can not be affected.

[0050] Please refer to Figure 4 As shown, in the embodiment, the upper frame 11 is provided with a receiving groove 110 recessed away from the lower frame 12, and the lower frame 12, the light emitter 2 and the light splitting member 3 are all partially received in the receiving groove 110. By arranging the receiving groove 110, the lamp 100 is made more light and thin.

[0051] Please refer to Figure 3 and Figure 4As shown, the light splitter 3 includes a first assembly portion 32 and a second assembly portion 33. The first assembly portion 32 is received in the receiving groove 110. In the radial direction of the light splitter 3, the second assembly portion 33 extends toward the diffuser 4 for a greater length than the first assembly portion 32. This forms 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 light splitter 3 is clamped and positioned within the assembly area 10 by the upper frame 11 and the diffuser 4. The provision of the boss 331 ensures that the light splitting surface 31 of the light splitter 3 always faces the light emitting element 2 for light splitting.

[0052] Please combine Figure 3 、 Figure 12 and Figure 13 As shown, preferably, the light splitter 3 is arranged around the periphery of the light emitting body 2, and the light splitting surface 31 of the light splitter 3 is arranged toward the light emitting body 2. The light splitter 3 is preferably an array of light splitting lenses, and the light splitting surface 31 is a concave-convex surface with peaks and troughs. This arrangement can ensure a good light splitting effect while eliminating the graininess of the light.

[0053] Please combine Figures 7 to 9 As shown, the axis of the light-emitting surface of the luminous element 2 is defined as the optical axis 20. In the direction perpendicular to the light emission of the luminous element 2, the optical axis 20 is lower than the centerline 41 of the diffuser 4. This arrangement allows the majority of the light emitted by the luminous element 2 to converge in the lower half of the diffuser 4, thereby allowing most of the light to radiate downward, facilitating the downward illumination of the lamp 100. The diffuser 4 surrounds the luminous element 2 and the beam splitter 3 and acts as a uniform light source in the direction of light emission from the luminous element 2.

[0054] Preferably, the optical axis 20 is 1-5 mm lower than the center line 41 of the diffusion cover 4. According to experiments, within this range, the light emitting effect of the lamp 100 is more outstanding.

[0055] The transparent member 5 is arranged around the outer periphery of the diffusion cover 4 and is spaced apart from the diffusion cover 4, so that the multi-color light emitted by the light emitter 2 can be totally reflected in the transparent member 5 after entering the transparent member 5. That is, a space 50 is left between the transparent member 5 and the diffusion cover 4, and at least part of the multi-color light emitted by the light emitter 2 and exiting from the diffusion cover 4 enters the transparent member 5 through the space 50, and then exits from the light exit surface 51 of the transparent member 5 after multiple times of total reflection between the light entrance surface and the light exit surface 51 of the transparent member 5. The transparent material of the transparent member 5 makes the light emission more transparent, thereby improving the user experience. The space 50 arranged between the transparent member 5 and the diffusion cover 4 can make the mixed light perform multiple times of total reflection on the inner and outer surfaces of the transparent member 5 while increasing the optical path of the mixed light, thereby further improving the visual transparency.

[0056] Preferably, the space 50 has a structure of being wide in the middle and narrow at both ends, that is, the middle space is wide and the spaces at both ends are narrow, so that the light path of the mixed light performing secondary refraction can be extended at the middle space position, thereby increasing the visual transparency.

[0057] Specifically, please refer to Figure 14 As shown in the figure, the light emitted from the transparent member 5 has excellent transparency, thereby improving the user experience.

[0058] Preferably, the transparent member 5 is a transparent ring body with non-uniform wall thickness, and the thickness of the transparent member 5 is maximum in the direction of the optical axis 20 of the light emitter 2 and is minimum in the direction away from the optical axis 20. Regardless of the direction, the thickness of the transparent member 5 is between 4.5 mm and 16 mm.

[0059] In the direction of the optical axis 20 of the light emitter 2, the thickness of the transparent member 5 increases from thick to thin and then thickens again, so that the transparent member 5 forms a structure similar to a concave lens with the middle thin and the two ends thick, to disperse the light as much as possible and expand the light irradiation surface. In addition, the non-uniform thickness of the transparent member 5 with the middle thin and the two ends thick makes the total reflection more at the middle position, the light emission stronger, the light emission weaker at both ends, and the visual transparency increased.

[0060] In this embodiment, the light emitter 2 is configured to emit light outward, which is to cooperate with the main light source to set the atmosphere. In other embodiments, the light emitter 2 can emit light inward to mix the light of the main light source and create an environmental atmosphere for the main light emitting surface of the lamp 100.

[0061] Specifically, please refer to Figure 10As shown, in this embodiment, the illuminator 2 includes at least two groups of light source assemblies 21, which are arranged in an up-down or left-right direction. Each group of light source assemblies 21 includes a light source board 211 and light-emitting units 212 disposed on the light source board 211. The light-emitting units 212 of two adjacent groups of light source assemblies 21 have different colors. In other words, multi-color light mixing is the mixing of two groups of light source assemblies 21 of different colors.

[0062] When at least two light source assemblies 21 are arranged vertically, the lamp 100 can be a tower-shaped lamp or a vertical lamp that is oriented from top to bottom. When at least two light source assemblies 21 are arranged vertically, the lamp 100 can be a strip-shaped lamp or a ring-shaped lamp.

[0063] Each set of light source assemblies 21 includes at least two light-emitting units 212 of different colors. These at least two light-emitting units 212 of different colors are assembled together and separated by a spacer 213. Each light-emitting unit 212 has a different color than its adjacent light-emitting unit 212. Thus, when the light-emitting units 212 of two adjacent sets of light source assemblies 21 have different colors, the mixed light from the two sets of light source assemblies 21 is actually a mixture of four colors, which can simulate a deeper ambient atmosphere.

[0064] For example, the first group of light source assemblies 21 includes light emitting units A and B, and the second group of light source assemblies 21 includes light emitting units C and D. In this case, the colors of the light emitting units 212 in two adjacent groups of light source assemblies 21 are different.

[0065] In other embodiments, it is also possible to consider that the first group of light source components 21 includes light-emitting units A and light-emitting units B, and the second group of light source components 21 includes light-emitting units A and light-emitting units C. This can also achieve mixed light, but the level of simulated environmental atmosphere is reduced.

[0066] Of course, two or more colors can also be mixed, and there is no limitation to this. It only needs to ensure that the light of two adjacent groups of light source assemblies 21 is different.

[0067] See also Figure 11 As shown, in another embodiment, the light-emitting body 2 includes at least four groups of light source assemblies 21, and the at least four groups of light source assemblies 21 are arranged in an array in the up and down and left and right directions. Each group of light source assemblies 21 includes a light source board 211 and a light-emitting unit 212 arranged on the light source board 211, and the colors of the light-emitting units 212 on two adjacent groups of light source assemblies 21 are different.

[0068] In this embodiment, only one light emitting unit 212 is provided on the light source plate 211, and therefore, when a deeper environmental atmosphere is to be simulated, at least four groups of light source assemblies 21 are required to be arranged in an array, so that when light is mixed in adjacent two columns, a good light mixing effect can be achieved.

[0069] The light emitting body 2 is provided with light source assemblies 21 with the same light emitting color on different columns, and on the nearest two columns, two light source assemblies 21 with the same light emitting color are arranged in an interlaced manner.

[0070] For example, the two light source assemblies 21 in the first column have light emitting units A and B respectively, the two light source assemblies 21 in the second column have light emitting units C and A respectively, and in order to ensure the light mixing effect, the two light emitting units A cannot be adjacent, and therefore, the two light source assemblies 21 with the light emitting unit A are arranged in an interlaced manner.

[0071] Suppose that the two light source assemblies 21 in the first column have light emitting units A and B respectively, and the two light source assemblies 21 in the second column have light emitting units C and D respectively, and at this time, there is no same light emitting unit 212 in the adjacent two columns of light source assemblies 21, and therefore, a deep environmental atmosphere can be simulated.

[0072] When the two light source assemblies 21 in the third column have light emitting units A and B respectively, if the two light source assemblies 21 with the light emitting unit A are arranged in the same row, the light mixing between A and C and between C and A will occur, which will seriously damage the light mixing effect. Therefore, at this time, the two light source assemblies 21 with the light emitting unit A also need to be arranged in an interlaced manner, so that in the first row, A and C are mixed, and C and B are mixed, and in the second row, B and D are mixed, and D and A are mixed.

[0073] In summary, the lamp 100 and the lamp assembly 400 of the utility model, on the one hand, the transparent piece 5 is arranged on the outer periphery of the diffusion cover 4, and the transparent piece 5 is arranged in a spaced manner with the diffusion cover 4, so that the light can be scattered out from the light emitting surface 51 of the transparent piece 5 after the light is incident to the transparent piece 5 through the diffusion cover 4, and the transparency in the human eye vision is achieved.

[0074] On the other hand, the light splitting piece 3 is arranged between the light emitting body 2 and the diffusion cover 4, and the mixing cavity 40 is arranged between the light splitting piece 3 and the diffusion cover 4, so that the multi-color light emitted by the light emitting body 2 is first incident to the mixing cavity 40 for light mixing after being split by the light splitting piece 3, and then is incident to the diffusion cover 4 and is emitted, so as to manufacture the environmental atmosphere; in addition, the array light splitting lens is used as the light splitting piece 3, and the light splitting surface of the light splitting piece 3 towards the light emitting body 2 is arranged as a concave-convex surface with a wave crest and a wave trough, so as to further strengthen the light splitting effect, and so that the multi-color light can intersect and complete the light mixing in a smaller space.

[0075] The above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
