[0026] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Here, it should be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, and other details less related to the present utility model are omitted.
[0028] In addition, it should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus.
[0029] Please refer to Figures 1 to 6 The present utility model provides a lighting fixture, comprising: a housing 100, a surface light source module 200, a surface light source mask 300, a side light source module 400 and a side light source mask 500.
[0030] The housing 100 includes: a chassis 110 and a side frame 120.
[0031] The side frame 120 is connected to and surrounds the chassis 110, and a receiving space 101 is formed between the chassis 110 and the side frame 120.
[0032] The surface light source module 200 is disposed on the chassis 110 and surrounded by the side frame 120.
[0033] The surface light source mask 300 is located in the receiving space and disposed opposite to the surface light source module 200.
[0034] In this embodiment, the surface light source mask 300 includes: a first diffuser plate 310.
[0035] Wherein, the surface 311 on the side of the first diffuser plate 310 facing away from the chassis 110 is a mirror surface.
[0036] The first diffuser plate 310 diffuses the light emitted by the surface light source module 200, distributing the line light source or point light source into a uniform surface light source. The first diffuser plate 310 can preferably eliminate the granularity of the light emitted from the surface light source module 200, and has the function of diffusing light, that is, light will be scattered on its surface, and the light will be softly and evenly spread out. After the light is diffused by the diffuser plate, the illumination area is larger, the light uniformity is better, and the chromaticity is stable.
[0037] In some embodiments, a very thin one-way film layer, such as tin, silver or aluminum, etc., is plated on the light-emitting surface of the first diffuser plate 310 by a crystal plating process to form a one-way film layer. The crystal plating process can make the one-way film layer have a relatively high smoothness, and the thickness of the one-way film layer can be adjusted according to the actual situation. When the thickness of the one-way film layer increases, its reflectivity and transmittance will change.
[0038] The side light source module 400 is disposed on the side frame 120. The side light source module 400 surrounds the first diffusion plate 310. Moreover, in the depth direction Z of the lamp, the distance between at least part of the light sources 410 of the side light source module 400 and the chassis 110 is greater than the distance between the first diffusion plate 310 and the chassis 110.
[0039] The side light source mask 500 is located in the accommodation space and faces the side light source module 400. The side light source mask 500 is disposed surrounding the surface light source mask 300.
[0040] In this embodiment, as Figure 4 shown, the light emitted by the side light source module 400 exits after passing through the side light source mask 500. Since the distance between at least part of the light sources 410 of the side light source module 400 and the chassis 110 is greater than the distance between the first diffusion plate 310 and the chassis 110, and the surface 311 on the side of the first diffusion plate 310 facing away from the chassis 110 is a mirror surface, therefore, at least part of the light exiting after passing through the side light source mask 500 will be incident on the surface 311 and then undergo Fresnel reflection, forming a clear virtual side light image matching the shape of the side light source mask 500 in the mirror surface. Thus, with a simple and low-cost structure, the depth sense of the lamp is increased, and the natural light effect of the window shadow at the window is realistically simulated.
[0041] In another embodiment, please refer to Figure 6 , the surface light source mask further includes: a transparent plate 320.
[0042] The transparent plate 320 is located on the side of the first diffusion plate 310 facing away from the chassis 110. The transparent plate 320 is fixedly attached to the first diffusion plate 310. Moreover, the surface 321 on the side of the transparent plate 320 facing away from the chassis 110 is a mirror surface. Thus, a double reflection is formed through the double-layer mirror surface, further increasing the depth sense of the lamp, and the simulation effect of the window shadow at the window is better. In addition, by fixedly attaching the transparent plate 320 on the light-emitting side of the first diffusion plate 310, the transparency when a person looks at the surface light source mask is further increased.
[0043] It should be noted that Figure 6 the gap between the transparent plate 320 and the first diffusion plate 310 in is for schematically showing that the transparent plate 320 and the first diffusion plate 310 are not integrally formed. Therefore, even if the two are fixedly attached, there will still be air between them.
[0044] Preferably, the orthographic projection of the light source of the surface light source module 200 is within the orthographic projection range of the first diffusion plate 310, and the orthographic projection of the light source of the surface light source module 200 is within the orthographic projection range of the transparent plate 320. In this way, the light source of the lamp is utilized more efficiently.
[0045] Further, the material of the transparent plate 320 includes quartz glass, PMMA or PC.
[0046] In some embodiments, in the depth direction Z of the lamp, the minimum distance between the light source 410 of the side light source module 400 and the chassis 110 is greater than or equal to the distance between the first diffuser plate 310 and the chassis 110. Thereby, the utilization efficiency of the light source 410 of the side light source module 400 is improved.
[0047] In some embodiments, the brightness of the side light source module 400 is higher than that of the surface light source module 200. Thereby, the window shadow can be made more obvious, and the authenticity of the simulation is further improved.
[0048] Further, the emission color of the side light source module 400 is different from that of the surface light source module 200. Thereby, the window shadow can be made more obvious, and the authenticity of the simulation is further improved.
[0049] In some embodiments, the side light source mask 500 is a second diffuser plate. Thus, similar to the principle of the first diffuser plate 300, the light of the side light source mask 500 can be made uniform.
[0050] In some embodiments, in the depth direction Z of the lamp, the side light source mask 500 has opposite top and bottom ends. The top end 501 is closer to the chassis 110 than the bottom end 502, and the top end 501 receives the periphery of the surface light source mask 300. Thus, there is no gap between the surface light source mask 300 and the side light source mask 500, resulting in strong integrity of surface emission and side emission and good simulation of real natural light effect.
[0051] Specifically, a connection groove is formed at the top end 501 of the side light source mask 500. The connection groove opens towards the chassis 110 and the surface light source mask 300. The surface light source mask 300 overlaps the bottom of the groove in the depth direction Z of the lamp, and the surface of the surface light source mask 300 on the side facing away from the chassis 110 contacts the bottom of the groove. Thus, the connection between the side light source mask 500 and the surface light source mask 300 and the fixation of the surface light source mask 300 are realized with a simple structure.
[0052] In some embodiments, one end of the side frame 120 away from the chassis 110 extends a frame connection portion 121 towards the accommodation space, and the bottom end 502 of the side light source mask 500 abuts against the free end of the frame connection portion 121. Thus, the fixation of the side light source mask 500 is realized.
[0053] In some embodiments, the housing 100 further includes: an inner frame 130.
[0054] The inner frame 130 is sleeved inside the side frame 120, and the inner frame 130 is located between the chassis 110 and the surface light source mask 300. One end of the inner frame 130 away from the chassis 110 abuts against the surface light source mask 300, and one end of the inner frame 130 away from the chassis 110 contacts the surface of the surface light source mask 300 on the side facing away from the chassis 110. Thus, the inner frame 130 further limits and fixes the surface light source mask 300.
[0055] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
