[0030] The sky lamp of the present application can effectively improve the authenticity of the optical effect formed by the light source assembly 3, and ensure that the blue sky simulation effect provided by the sky lamp is closer to the real sky effect.

[0031] In one specific embodiment of the present application, as Figures 1 to 7As shown, the sky lamp comprises a shell 1 and a blue sky module 2. The shell 1 is formed with a first inner side wall 11 and a second inner side wall 12, the first inner side wall 11 and the second inner side wall 12 are staggered with each other and surround to form a light emitting cavity 22. The shell 1 is provided with a mounting position 21, the blue sky module 2 is mounted on the mounting position 21, and the light emitting surface of the blue sky module 2 faces the light emitting cavity 22. The first inner side wall 11 is formed with an opening 13, and the inside of the opening 13 is provided with a light source assembly 3. The opening 13 is connected with a light cutting plate 31, the light cutting plate 31 is formed with a light cutting hole 311 with a preset shape, the light path of the light source assembly 3 passes through the light cutting hole 311 and irradiates to the second inner side wall 12.

[0032] 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, so that the sky lamp can simulate the light and shadow effect of the sky; at the same time, the light path of the light source assembly 3 irradiates to the second inner side wall 12, so as to realize the light and shadow effect of simulating the similar sunlight incident window on the inner side wall of the shell 1.

[0033] In the process that the light path of the light source assembly 3 irradiates to the inner side wall of the shell 1, the light of the light source assembly 3 irradiates to the light cutting plate 31 formed with the light cutting hole 311 with a preset shape, and the preset shape of the light cutting hole 311 is enlarged and irradiated to the second inner side wall 12, so that the light source assembly 3 can form the atmosphere light spot with a preset shape on the second inner side wall 12 and form a clear cut-off line, the overall effect of the light irradiated to the second inner side wall 12 by the light source assembly 3 is more uniform, the authenticity of the optical effect formed by the light source assembly 3 is effectively improved, and the simulation effect of the blue sky provided by the sky lamp is closer to the real sky effect.

[0034] It should be noted that the shell 1 is formed with two opposite first inner side walls 11 and two opposite second inner side walls 12, and each first inner side wall 11 is adjacent to two second inner side walls 12, so that the first inner side wall 11 and the second inner side wall 12 surround to form the light emitting cavity 22.

[0035] In order to further ensure that the simulation light and shadow effects presented by the two opposite second inner side walls 12 of the shell 1 are uniform and consistent, as shown in Figure 1 and Figure 2 As shown, the openings 13 are symmetrically arranged at the two ends of the first inner side wall 11, and each opening 13 is detachably connected with a light cutting plate 31, so that each second inner side wall 12 can be irradiated by a group of light source assemblies 3 to present a simulation light spot with a clear cut-off line, and the sunlight oblique window simulation effect of each group of light source assemblies 3 on the two second inner side walls 12 is ensured. At the same time, since the opening 13 is located at the end of the first inner side wall 11, the light transmission path of the light source assembly 3 can be effectively reduced, so as to effectively reduce the light energy loss of the light source assembly 3 in the transmission process.

[0036] As shown in Figure 2 andFigure 4 As shown, the opening size of the light cutting hole 311 gradually decreases along a predetermined direction, wherein the predetermined direction is from the middle of the first inner side wall 11 to the end of the first inner side wall 11. Furthermore, the light spot irradiated by the light source assembly 3 to the second inner side wall 12 can gradually decrease in the direction from the distal end of the second inner side wall 12 to the first inner side wall 11, and form a uniform light and shade transition at the end of the second inner side wall 12 close to the light source assembly 3, so as to further ensure that the simulated light and shadow effect presented by the sky lamp on the second inner side wall 12 is more natural, and ensure that the sky lamp can provide a more realistic sunlight incident window light and shadow effect.

[0037] Specifically, as shown in Figures 3 to 5 , the light source assembly 3 comprises an atmosphere light source 32 and a condenser lens 33, the atmosphere light source 32 is connected to the inside of the opening hole 13 through a light source fixing plate 34, and the condenser lens 33 covers the light emitting surface of the atmosphere light source 32. When the atmosphere light source 32 is powered on and emits light, the light passes through the condenser lens 33 and converges, and most of the light is condensed towards the light cutting hole 311 of the light cutting plate 31, so that most of the light can be irradiated to the two second inner side walls 12 through the light cutting hole 311, thereby reducing light loss and effectively improving the brightness of the atmosphere light source 32 irradiated on the two second inner side walls 12.

[0038] Further, in order to facilitate the installation of the atmosphere light source 32 and the condenser lens 33, as shown in Figure 4 and Figure 5 , the light source assembly 3 further comprises a connecting seat 35, the light source fixing plate 34 is installed on the connecting seat 35, the connecting seat 35 is detachably connected with the inner wall surface of the opening hole 13, and the light cutting plate 31 is arranged on the connecting seat 35, so as to adjust the installation position of the atmosphere light source 32 according to the actual lighting condition, and ensure the irradiation effect of the atmosphere light source 32 on the two second inner side walls 12.

[0039] Among them, in order to detachably connect the connecting seat 35 with the inner wall surface of the opening hole 13, a connecting column can be formed in the connecting seat 35, and the connecting column is threadedly connected with the inner wall surface of the opening hole 13, so as to adjust and maintain the atmosphere light source 32. In addition, the connection mode between the connecting seat 35 and the inner wall surface of the opening hole 13 is not limited to threadedly connecting through the connecting column, but a sliding column can also be formed on the inner wall surface of the opening hole 13, and a connecting sliding groove is correspondingly formed in the connecting seat 35, the sliding column is slidably connected with the connecting sliding groove, and by adjusting the installation position of the sliding column in the connecting sliding groove, the installation position of the atmosphere light source 32 can be conveniently adjusted, and the lighting effect of the atmosphere light source 32 can be correspondingly adjusted.

[0040] Further, as shown in Figure 4 and Figure 5As shown in the figure, the heat dissipation plate 36 is arranged between the light source fixing plate 34 and the connecting seat 35, wherein the heat dissipation plate 36 is preferably an aluminum plate, the heat dissipation plate 36 can absorb the heat generated by the atmosphere light source 32 when the atmosphere light source 32 emits light, and dissipate to the rear of the heat dissipation plate 36, so as to ensure that the atmosphere light source 32 can stably emit light, and prolong the service life of the atmosphere light source 32.

[0041] In the embodiment, as shown in the figure, Figure 2 The atmosphere light source 32 is located away from the second inner side wall 12 at one end of the light cutting hole 311, so that the atmosphere light source 32 and the light cutting hole 311 of the light cutting plate 31 are arranged in a staggered manner, and the light of the atmosphere light source 32 can be obliquely illuminated into the second inner side wall 12 from the light cutting hole 311, thereby further ensuring that the light cutoff line of the light irradiated to the second inner side wall 12 is clear and obvious, and the simulation incidence effect of the atmosphere light source 32 is ensured.

[0042] In the embodiment of the utility model, as shown in the figure, Figure 6 The blue sky module 2 includes a blue sky light source 23, a scattering light guide plate 24 and a reflection plate 25, the light entrance surface of the scattering light guide plate 24 is arranged on the side of the scattering light guide plate 24, and the blue sky light source 23 faces the light entrance surface of the scattering light guide plate 24.

In the embodiment, the scattering light guide plate 24 is a Rayleigh scattering light guide plate.

[0043] It can be understood that when the light of the blue sky light source 23 is irradiated 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 irradiated from the light exit surface of the scattering light guide plate 24 to the light emitting cavity 22, and the other part of the light is refracted into the reflection plate 25 through the scattering light guide plate 24, and then irradiated into the scattering light guide plate 24 after being reflected by the reflection plate 25, and then scattered or reflected again by the micro-nano particles in the scattering light guide plate 24, and then corresponding to the light exit surface of the scattering light guide plate 24 or re-reflected to the reflection plate for secondary or multiple reflections.

[0044] Further, the scattering light guide plate 24 and the reflection plate 25 can make the light of the blue sky light source 23 into multiple parts of light irradiated at intervals, 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 multiple parts of light, so that the blue sky atmosphere scattering light irradiated by the blue sky module 2 has a certain stereoscopic feeling, and the blue sky effect of the blue sky module 2 is more deep and stereoscopic.

[0045] In addition, by arranging the blue sky light source 23 on the side of the scattering light guide plate 24, the space for accommodating the blue sky light source 23 is not needed to flow out at the back of the scattering light guide plate 24, which significantly reduces the overall thickness of the sky lamp, thereby facilitating the installation of the sky lamp and reducing the cost of the mold.

[0046] It should be noted that, as Figure 6 shown, 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 is used to wrap the reflecting plate 25, the scattering light guide plate 24 and the blue sky light source 23 as a whole, thereby avoiding the mutual movement of the components of the blue sky module 2 when the sky lamp is moved, and affecting the light output effect of the blue sky module 2.

[0048] In order to ensure the installation stability of the blue sky module 2 in the shell 1, as Figure 7 shown, the shell 1 comprises an inner frame 14 and an outer frame 15, the inner frame 14 and the outer frame 15 are connected to form a mounting cavity 16, the light source assembly 3 is arranged in the mounting cavity 16, the first inner side wall 11 and the second inner side wall 12 are formed on the inner frame 14, the side of the inner frame 14 facing the outer frame 15 is formed with a limiting rib 17, and the mounting position 21 is formed between the top surface of the inner frame 14 and the top wall surface of the shell 1, and the distance between the top surface of the inner frame 14 and the top wall surface of the shell 1 is the same as the thickness of the blue sky module 2. Further, the mounting position 21 is formed between the top surface of the inner frame 14 and the top wall surface of the shell 1, so that the blue sky module 2 is fixedly installed on the top of the shell 1 by limiting cooperation between the top surface of the inner frame 14 and the top wall surface of the shell 1, thereby effectively ensuring the installation stability of the blue sky module 2.

[0049] Of course, the forming mode of the mounting position 21 is not limited to limiting cooperation between the top surface of the inner frame 14 and the top wall surface of the shell 1, but a connecting hole can also be arranged on the top wall surface of the shell 1, and a connecting column is arranged on the outer wall surface of the fixed frame 26 of the blue sky module 2, the connecting column is inserted into the connecting hole, and then the fixed frame 26 is detachably connected to the top wall surface of the shell 1 by bolts or studs, wherein the mounting position 21 is the connecting hole and the connecting column.

At the same time, since the light path of the lighting module 4 is away from the light-emitting cavity 22, the light emitted by the lighting module 4 will not be blocked by the shell 1, so that the light of the lighting module 4 can be irradiated to the use area, and the light efficiency of the lighting module 4 is effectively improved.
