[0032] The sky lamp can make the light and shadow effect simulated by the side atmosphere module 3 more natural, and make the sky lamp provided blue sky simulation effect more close to the real sky effect.

[0033] In the embodiment of the utility model, as shown in Figures 1 to 7 The shell 1 is provided with a mounting position 21, the blue sky module 2 is arranged on the mounting position 21, a plurality of inner side walls of the shell 1 enclose to form a light emitting cavity 22, and the light emitting surface of the blue sky module 2 faces the light emitting cavity 22. At least one inner side wall is provided with a mounting hole 11, the side atmosphere module 3 is arranged on the mounting hole 11, the side atmosphere module 3 is formed with a preset light path, the preset light path irradiates to other inner side walls, and the opening edge of the mounting hole 11 is located on the preset light path.

[0034] According to the sky lamp of the embodiment, the three-dimensional blue sky atmosphere light is irradiated to the light emitting cavity 22 by the blue sky module 2, the light and shadow effect similar to the sky can be realized, and the preset light path of the side atmosphere module 3 irradiates to other inner side walls of the shell 1, the light and shadow effect similar to the sunlight irradiating to the window can be simulated on the inner side walls of the shell 1.

[0035] When the preset light path of the side atmosphere module 3 irradiates to the inner side wall of the shell 1, the opening edge of the mounting hole 11 is located on the preset light path of the side atmosphere module 3, part of light of the side atmosphere module 3 can be shielded and cut off by the opening edge of the mounting hole 11, so that the side atmosphere module 3 can form an obvious cut-off line when irradiating to other inner side walls, thereby forming a soft transition area on other inner side walls, the overall transition of light is more uniform and natural, the light and shadow effect simulated by the side atmosphere module 3 when the sunlight irradiates to the window is more natural, and the blue sky simulation effect provided by the sky lamp is more close to the real sky effect.

[0036] As shown in Figures 1 to 3 The side atmosphere module 3 includes a mounting box 31, a light source plate 32 and a light emitting piece 33, the mounting box 31 is detachably connected to the shell 1, the mounting box 31 is formed with a notch, the opening end of the notch is inserted into the mounting hole 11, so that the mounting stability of the light source plate 32 and the light emitting piece 33 on the inner side wall of the shell 1 is ensured by cooperation of the mounting box 31 and the mounting hole 11.

[0037] The light source plate 32 is installed at the bottom of the slot, the light emitting element 33 is arranged on the light source plate 32, and the light emitting part of the light emitting element 33 is located inside the slot. Further, when the light emitting element 33 emits light, the size of the light spot irradiated by the light emitting element 33 to the outside can be controlled by the size of the slot of the mounting box 31, and by the cooperation between the slot and the opening edge of the mounting hole 11, after the light of the light emitting element 33 is emitted from the mounting box 31, it is ensured that the light spot of the light emitting element 33 can form a clear cutoff line on the other inner side wall, so as to ensure the light and shadow simulation effect of the side atmosphere module 3 on the sunlight side irradiated to the window.

[0038] In addition, by limiting the light emitting angle of the light emitting element 33 by the slot of the mounting box 31, it can also avoid the light of the light emitting element 33 from irradiating to the blue sky module 2, thereby protecting the blue sky simulation effect of the blue sky module 2.

[0039] Specifically, in order to ensure that the slot of the mounting box 31 can limit the light emitting angle of the light emitting element 33, as shown in Figure 1 , the opening surface of the slot is flush with the opening edge of the mounting hole 11, and the height of the slot is 12-20mm, and the depth of the slot is 20-30mm, so that the slot of the mounting box 31 can completely accommodate the light source plate 32 and the light emitting element 33, and avoid the light emitting element 33 protruding out of the slot of the mounting box 31.

[0040] At the same time, the width of the slot is 110-130mm, so as to ensure that the light spot irradiated by the light emitting element 33 to the other inner side wall can cover the other inner side wall.

[0041] Preferably, the height of the slot of the mounting box 31 is 14mm, the width is 120mm, and the depth is 20mm, which ensures that the light emitting angle of the light emitting element 33 is limited, and at the same time, the light spot cutoff line of the light emitting element 33 irradiated to the other inner side wall is more sharp, and the light is uniform, further ensuring that the simulation effect of the side atmosphere module 3 is more natural.

[0042] It should be noted that the light emitting element 33 is preferably a lamp source capable of emitting divergent light, such as an LED lamp source, so as to increase the coverage area of the light of the light emitting element 33 on the other inner side wall.

[0043] Specifically, in order to further ensure that the simulation effect of the side atmosphere module 3 on the inner side walls of the two sides is uniform, as shown in Figure 1 and Figure 2 , at least two mounting holes 11 are symmetrically arranged on one inner side wall, and a group of side atmosphere modules 3 are arranged in each mounting hole 11, so that at least two groups of side atmosphere modules 3 are symmetrically arranged on the inner side wall, and the symmetrically arranged side atmosphere modules 3 can form consistent and sharp atmosphere light spots on the two inner side walls at the same time, thereby ensuring the simulation effect of each group of side atmosphere modules 3 on the sunlight oblique irradiation of the two inner side walls.

[0044] As shown inFigure 2 As shown, the light emitting piece 33 is located at one end of the mounting hole 11, and the one end of the mounting hole 11 is close to the middle of the inner side wall, that is, the light emitting piece 33 is arranged at the end of the mounting hole 11 away from the irradiated inner side wall, which can effectively ensure the light spot area of the light emitting piece 33 irradiated to the two side inner side walls, thereby further ensuring the light and shadow simulation effect of the side atmosphere module 3 on the sun oblique window.

[0045] In another embodiment of the present application, as shown in Figure 4 As shown, the light source plate 32 is inclinedly arranged in the mounting box 31, the notch is provided with a light cutting baffle 34, the light emitting piece 33 faces the light cutting baffle 34, the light cutting baffle 34 is formed with a light cutting edge 35, and the light path of the light emitting piece 33 irradiates to other inner side walls through the light cutting edge 35.

[0046] Further, when the light emitting piece 33 emits light, part of the light irradiates to the light cutting baffle 34, and another part is emitted to other inner side walls from outside the light cutting edge 35 of the light cutting baffle 34. Under the cut-off of the light cutting baffle 34, the light of the light emitting piece 33 can also form a sharp cut-off line at the other inner side wall, thereby also achieving the light and shadow effect of simulating a sun oblique window, and further enabling the sky lamp to provide a real blue sky simulation effect.

[0047] In addition, since the light emitting piece 33 is inclinedly arranged in the mounting box 31 through the light source plate 32, the part of the light emitted from outside the light cutting edge 35 of the light cutting baffle 34 can irradiate to the far end of the two side inner side walls, and form a certain light-dark transition between the far end of the two side inner side walls and the near end of the two side inner side walls. And further avoid the light of the light emitting piece 33 irradiating to the blue sky module 2, to prevent the blue sky module from appearing glare phenomenon.

[0048] It should be noted here that the inclination angle between the light source plate 32 and the mounting box 31 can be adjusted according to the length of the two side inner side walls, so that the light spot of the light emitting piece 33 after being cut by the light cutting baffle 34 can cover the two side inner side walls.

[0049] Specifically, the light cutting baffle 34 is arranged with light absorbing flannel 36, which absorbs the light irradiated to the light cutting baffle 34, further ensuring that the light emitting piece 33 can form a more obvious sharp cut-off line after being cut by the light cutting baffle 34, and avoiding ghosting.

[0050] In another embodiment of the present application, as shown in Figure 5As shown, the side atmosphere module 3 includes a surface light source 37 arranged on the inner side wall, and the light path of the surface light source 37 is directed towards the light emitting cavity 22. The surface light source 37 can be a cold light sheet or an OLED surface light source 37, and the surface light source 37 arranged on the inner side wall of the shell 1 is powered to emit light, which can also simulate the sunlight obliquely shining into the window, so that the sky lamp can also cooperate with the surface light source 37 and the blue sky module to provide a more realistic blue sky simulation effect.

[0051] It should be noted that the boundary shape of the surface light source 37 can be adaptively set according to actual needs, and by setting the boundary shape of the surface light source 37, the sky lamp can also ensure that the light and shadow effect of the simulated sunlight forms a clear cutoff line, thereby achieving a clear light-dark transition.

[0052] It should be further noted that the surface light source 37 is provided with two surface light sources 37 arranged on the opposite two inner side walls.

[0053] In the embodiment of the present application, as shown in Figure 6 The blue sky module 2 includes a blue sky light source 23, a scattering light guide plate 24 and a reflecting plate 25.

The reflecting surface of the scattering light guide plate 24 is arranged opposite to the light exit surface, the reflecting plate 25 is located on the reflecting surface of the scattering light guide plate 24, and the light exit surface of the scattering light guide plate 24 is directed towards the light emitting cavity 22. In this embodiment, the scattering light guide plate 24 is a Rayleigh scattering light guide plate 24.

[0054] It can be understood that when the light of the blue sky light source 23 shines into the scattering light guide plate 24 from the light entrance surface of the scattering light guide plate 24, part of the light is scattered by the micro-nano particles in the scattering light guide plate 24 and directly shines towards the light emitting cavity 22 from the light exit surface of the scattering light guide plate 24; and the other part of the light is refracted into the reflecting plate 25 through the scattering light guide plate 24, and after being reflected by the reflecting plate 25, it is washed and shines into the scattering light guide plate 24 again, and then is scattered or reflected by the micro-nano particles in the scattering light guide plate 24 again, and then is correspondingly emitted from the light exit surface of the scattering light guide plate 24 or is reflected back to the reflecting plate for secondary or multiple reflections.

[0055] Further, the scattering light guide plate 24 and the reflecting plate 25 can divide the light of the blue sky light source 23 into multiple parts of light, and the light exit surface of the scattering light guide plate 24 can present a visual effect of superimposed blue sky effect by using the superposition of the multiple parts of light, so that the blue sky atmosphere scattering light emitted by the blue sky module 2 has a certain stereoscopic effect, and the blue sky effect of the blue sky module 2 is more deep and stereoscopic.

[0056] In addition, by arranging the blue sky light source 23 on the side of the scattering light guide plate 24, the accommodation space of the blue sky light source 23 is not required to flow out at the back of the scattering light guide plate 24, the overall thickness of the sky lamp is significantly reduced, the installation of the sky lamp is facilitated, and the cost of the mold is reduced.

[0057] Further, as shown in Figure 6 and Figure 7 , the blue sky module 2 further comprises a fixed frame 26, the scattering light guide plate 24 and the reflecting plate 25 are stacked in the fixed frame 26 in sequence, and the blue sky light source 23 is arranged on the inner side wall of the fixed frame 26, so that the fixed frame 26 wraps the reflecting plate 25, the scattering light guide plate 24 and the blue sky light source 23 as a whole, and the mutual movement of the components of the blue sky module 2 is avoided when the sky lamp moves, thereby affecting the light output effect of the blue sky module 2.

[0058] Preferably, the fixed frame 26 is formed by pressing aluminum material, the fixed frame 26 is a square frame structure, and a plurality of blue sky light sources 23 are arranged on the inner side wall of the fixed frame 26 at an interval, and the number of the blue sky light sources 23 can be adjusted according to specific scenes and requirements, and the number of the blue sky light sources 23 is not limited herein.

[0059] In order to ensure the installation stability of the blue sky module 2 in the shell 1, as shown in Figure 7 , a limiting frame 27 is formed on the top of the shell 1, a supporting surface 28 is formed on one side of the top wall surface of the shell 1, an installation position 21 is formed between the supporting surface 28 and the top wall surface of the shell 1, and the distance between the supporting surface 28 and the top wall surface of the shell 1 is equal to the thickness of the fixed frame 26.
