Only this statement, the up, down, left, right, front, back, inside, outside and other directions of the utility model appearing or about to appear in the text are based on the drawings of the utility model, and it is not a specific limitation on the utility model.

[0031] The clear sky lamp can significantly improve the light brightness of the clear sky lamp irradiated to the outside of the shell 1, and effectively improve the lighting efficiency and lighting effect of the clear sky lamp.

[0032] In one specific embodiment of the present application, as shown in the drawings, Figures 1 to 7 The clear sky lamp comprises a shell 1 and a blue sky module 2. The blue sky module 2 is arranged inside the shell 1, the inner side wall of the shell 1 is enclosed to form a light emitting cavity 101, and the light emitting surface of the blue sky module 2 faces the light emitting cavity 101. The outer side wall of the shell 1 is provided with a lighting box body 31, the side of the lighting box body 31 away from the light emitting cavity 101 is formed with a light emitting surface 311, and the light emitting surface 311 forms a predetermined angle with the inner side wall of the shell 1. The lighting box body 31 is internally arranged with a lighting light source 32 and a reflecting cup 33, the light emitting surface of the lighting light source 32 faces the reflecting surface 331 of the reflecting cup 33, the reflecting surface 331 of the reflecting cup 33 faces the light emitting surface 311, and the reflecting surface 331 of the reflecting cup 33 is a curved surface.

[0033] According to the clear sky lamp of the present embodiment, the blue sky module 2 can irradiate a three-dimensional blue sky atmosphere light to the light emitting cavity 101 of the shell 1 to correspondingly realize the light and shadow effect of the clear sky lamp simulating the sky. Meanwhile, the lighting light source 32 arranged on the outer side wall of the shell 1 can irradiate lighting light to the reflecting surface 331 of the reflecting cup 33, and the reflecting surface 331 of the reflecting cup 33 can irradiate the light of the lighting light source 32 from the light emitting surface 311 of the lighting box body 31 to the outside of the shell 1 to realize the lighting effect of the clear sky lamp simulating the sunlight irradiating the house.

[0034] Since the reflecting surface 331 of the reflecting cup 33 is a curved surface, the reflecting cup 33 can not only reflect the light of the lighting light source 32, but also can concentrate the light of the lighting light source 32 by using the curved reflecting surface 331, or can irradiate the light of the lighting light source 32 in a nearly parallel manner, so that the light of the lighting light source 32 is enhanced in a specific area, and the light can be more uniformly irradiated from the light emitting surface 311 of the lighting box body 31, thereby significantly improving the light brightness of the clear sky lamp irradiated to the outside of the shell 1, and effectively improving the lighting efficiency and lighting effect of the clear sky lamp.

[0035] It should be noted that the lighting light source 32 is arranged in the lighting box body 31 by a light source fixing plate, and the lighting light source 32 adopts a light source such as an adjustable color temperature lamp bead, for example, a double-color temperature COB lamp bead or an adjustable color temperature LED lamp bead, so as to simulate the light and shadow effect of the sunlight irradiated into the window at different time periods.

[0036] Further, as shown in the drawings, Figure 3As shown, the reflecting surface of the reflecting cup 33 is formed with a plurality of circular-arc reflecting concaves 332, which are connected to form the reflecting surface 331, so that the reflecting cup 33 forms a convex reflecting cup, thereby ensuring that the light rays of the illumination light source 32 can be more effectively scattered and homogenized when reflected and condensed by the reflecting cup 33, further improving the light brightness and illumination effect of the light exit surface 311 of the illumination box 31. Meanwhile, when the light rays of the illumination light source 32 are irradiated to the wall surface after being reflected and condensed by the convex reflecting cup, a boundary-sharp and regular-shaped irradiation spot can be formed, without producing glare, so that the simulated illumination effect of the sunny sky lamp can be closer to the light and shadow effect of the real sunlight penetrating through the window and irradiating the house, further improving the light efficiency of the sunny sky lamp.

[0037] It should be further noted that the reflecting surface 331 of the reflecting cup 33 can also be a convex structure. When the light rays of the illumination light source are irradiated to the convex reflecting surface of the reflecting cup 33, the light rays of the illumination light source 32 can form parallel light columns or nearly parallel light columns to irradiate to the light exit surface of the illumination box, improving the light brightness of the sunny sky lamp irradiated to the outside of the shell 1.

[0038] Further, in order to ensure the installation stability of the reflecting cup 33 in the illumination box 31, as shown in Figure 4 and Figure 5 , the inner top wall of the illumination box 31 is provided with a reflecting cup fixing plate 312, and the side of the reflecting cup 33 away from the illumination light source 32 is provided with a connecting piece 333, which is detachably connected with the reflecting cup fixing plate 312. In the embodiment, the connecting piece 333 can be a connecting column formed on the back of the reflecting cup 33, and the connecting column is integrally formed with the reflecting cup 33. By detachably connecting the connecting piece 333 and the reflecting cup fixing plate 312, the reflecting cup 33 is fixedly installed on the inner top wall of the illumination box 31, so as to ensure the relative position between the reflecting cup 33 and the illumination light source 32, avoid the reflecting cup 33 from shaking or deviating when the sunny sky lamp is moved, and ensure the light exit effect of the sunny sky lamp.

[0039] Preferably, a plurality of threaded holes are arranged on the reflecting cup fixing plate 312, and a plurality of threaded columns are arranged on the end surface of the connecting column away from the reflecting cup 33, each threaded column is arranged in a corresponding threaded hole, and the threaded connection is realized by a nut.

[0040] In the embodiment, as shown in Figure 2 , Figure 4 and Figure 5As shown, the light emitting surface 311 is formed with a light emitting hole 314, the area of the light emitting hole 314 is S1, the projection area of the reflecting surface of the reflecting cup 33 on the light emitting surface 311 is S2, S1 is greater than or equal to S2, so that under the reflection and condensation of the plurality of arc reflecting concave surfaces, the light path of the light reflected by the reflecting cup 33 can be completely irradiated to the outside of the shell 1 through the light emitting hole 314 without being blocked, thereby improving the light emitting efficiency of the illumination light source 32 and further ensuring the light energy utilization rate of the illumination light source 32.

[0041] In this embodiment, as shown in the figure, Figure 2 As shown, the outer side wall and the inner side wall of the shell 1 form a mounting cavity 301 separated from the light emitting cavity 101, and the illumination box body 31 is located in the mounting cavity 301 to wrap the illumination box body 31 with the mounting cavity 301, so as to avoid the illumination box body 31 from being exposed to accumulate dust, and at the same time avoid the illumination light source 32 and the reflecting cup 33 from being exposed to attract mosquitoes, thereby ensuring the light emitting effect of the illumination light source 32 and the reflecting cup 33.

[0042] The illumination box body 31 is rotationally connected with the mounting cavity 301 through a rotating shaft 315, so as to drive the illumination box body 31 to rotate by adjusting the rotation angle of the rotating shaft 315, thereby adjusting the light emitting angle of the light emitting surface 311 of the illumination box body 31 to adapt to different installation distances of the user, ensure the spot effect of the illumination module irradiated to the wall, and meet the actual use requirements of the user.

[0043] Specifically, the illumination box body 31 is fixedly connected with the rotating shaft 315, the rotating shaft 315 is rotationally arranged in the outer wall of the shell 1, the outer wall of the shell 1 is rotationally provided with an adjusting member 316, the adjusting member 316 is rotationally connected with the end portion of the rotating shaft 315, and the adjusting member 316 is used for adjusting the relative angle between the illumination box body 31 and the mounting cavity 301. The adjusting member 316 can be a knob arranged on the outer wall of the shell 1, and when it is necessary to adjust the relative angle between the illumination box body 31 and the mounting cavity 301, the knob can be rotated to drive the rotating shaft 315 to rotate relative to the mounting cavity 301, thereby changing the light emitting angle of the illumination box body 31.

[0044] And by adjusting the angle of the illumination box body 31 through the adjusting member 316 arranged on the outer wall of the shell 1, the operation of the user in adjusting the light emitting angle of the clear sky lamp can be effectively simplified, thereby reducing the operation steps of the user and improving the use experience of the user.

[0045] It should be noted that when a plurality of illumination modules are arranged in the mounting cavity 301, the rotating shaft 315 is arranged in the plurality of illumination box bodies 31, and the rotating shaft 315 is located above the reflecting cup fixing plate 312, so as to simultaneously control the rotation of the plurality of illumination box bodies 31 through the adjusting member 316.

[0046] In this embodiment, as shown in the figure, Figure 1As shown, the outer side wall of the shell 1 is provided with a light-transmitting piece 11, the light-transmitting piece 11 covers the light-emitting surface 311, and the reflecting surface of the reflecting cup 33 faces the light-transmitting piece 11. The light-transmitting piece 11 is preferably a transparent cover which can be detachably connected to the outer side wall of the shell 1 by bolt connection or buckle connection. By covering the light-emitting surface 311 with the light-transmitting piece 11, the lighting light source 32 and the reflecting cup 33 in the lighting box 31 can be covered and shielded by the light-transmitting piece 11, so that the dust and insects in the external environment do not affect the light-emitting effect of the reflecting cup 33, and the light-transmitting piece 11 does not affect the light-emitting efficiency of the lighting light source 32, thereby ensuring that the clear sky lamp can achieve good lighting effect.

[0047] In the embodiment of the utility model, as shown in Figure 4 and Figure 7 As shown, the blue sky module 2 comprises a blue sky light source 21, a scattering light guide plate 22 and a reflecting plate 23, the light-incident surface of the scattering light guide plate 22 is arranged on the side of the scattering light guide plate 22, the blue sky light source 21 faces the light-incident surface of the scattering light guide plate 22, the reflecting surface of the scattering light guide plate 22 is oppositely arranged with the light-emitting surface 311, the reflecting plate 23 is located on the reflecting surface of the scattering light guide plate 22, and the light-emitting surface 311 of the scattering light guide plate 22 faces the light-emitting cavity 101. The scattering light guide plate 22 is a Rayleigh scattering light guide plate 22.

[0048] It can be understood that when the light of the blue sky light source 21 is incident on the scattering light guide plate 22 from the side, part of the light is scattered by the micro-nano particles in the scattering light guide plate 22 and directly irradiates the light-emitting cavity 101 from the light-emitting surface 311 of the scattering light guide plate 22, and the other part of the light is refracted into the reflecting plate 23 through the scattering light guide plate 22, is reflected by the reflecting plate 23, and then reenters the scattering light guide plate 22, and is scattered or reflected again by the micro-nano particles in the scattering light guide plate 22, and then is emitted from the light-emitting surface 311 of the scattering light guide plate 22 or is reflected back to the reflecting plate 23 for secondary or multiple reflection.

[0049] Further, the scattering light guide plate 22 and the reflecting plate 23 can divide the light of the blue sky light source 21 into multiple parts of light which are emitted at intervals, so that the light-emitting surface 311 of the scattering light guide plate 22 can present a visual experience of superimposed blue sky effect, thereby making the blue sky atmosphere scattered light emitted by the blue sky module 2 have a certain stereoscopic effect, and ensuring that the blue sky effect of the blue sky module 2 is more deep and stereoscopic.

[0050] In addition, by arranging the blue sky light source 21 on the side of the scattering light guide plate 22, the accommodation space of the blue sky light source 21 is not required to be left on the back of the scattering light guide plate 22, thereby significantly reducing the overall thickness of the clear sky lamp, facilitating the installation of the clear sky lamp, and reducing the cost of the mold.

[0051] It should be noted that, as shown in Figure 7As shown, the blue sky module 2 further comprises a fixed frame 25, the scattering light guide plate 22 and the reflecting plate 23 are stacked in the fixed frame 25 in sequence, and the blue sky light source 21 is arranged on the inner side wall of the fixed frame 25, so that the fixed frame 25 wraps the reflecting plate 23, the scattering light guide plate 22 and the blue sky light source 21 as a whole, thereby avoiding the mutual movement of the components of the blue sky module 2 when the sunny sky lamp moves, and affecting the light output effect of the blue sky module 2.

[0052] Preferably, the color temperature of the blue sky light source 21 is 6880-8100K, the main wavelength is 484nm, and the red, green and blue ratios are 15.1%, 78.2% and 6.6%, respectively.

[0053] Further, as shown in the drawings, Figure 7 The blue sky module 2 further comprises a light-transmitting plate 24, the light-transmitting plate 24 is located on the light output surface 311 of the scattering light guide plate 22, and the size of the light-transmitting plate 24 is greater than that of the scattering light guide plate 22, so as to cover the scattering light guide plate 22 by the light-transmitting plate 24, protect the scattering light guide plate 22, prevent scratches on the light output surface 311 of the scattering light guide plate 22, and prevent dust from adhering to the light output surface 311 of the scattering light guide plate 22 to ensure the light output effect of the scattering light guide plate 22. Preferably, the light-transmitting plate 24 is a transparent plate material with high light transmittance, so as to protect the scattering light guide plate 22 by the light-transmitting plate 24 while avoiding affecting the light output effect of the scattering light guide plate 22.

[0054] In the embodiments of the utility model, in order to further improve the authenticity of the sunny sky lamp blue sky simulation effect, as shown in the drawings, Figure 1 、 Figure 4 and Figure 6 The sunny sky lamp further comprises a side atmosphere module 4. The shell 1 is formed with staggered first inner side wall 102 and second inner side wall 103, first inner side wall 102 is formed with mounting hole 12, side atmosphere module 4 is arranged in mounting hole 12. The mounting hole 12 is connected with the light cutting plate 41, the light cutting plate 41 is formed with the light cutting hole 411, the atmosphere light path of the side atmosphere module 4 passes through the light cutting hole 411 and irradiates to the second inner side wall 103, and the light and shadow effect of the sun irradiating the window side wall surface can be simulated on the second inner side wall 103 by the side atmosphere module 4.

[0055] It can be understood that when the atmosphere light path of the side atmosphere module 4 irradiates to the inner side wall on both sides of the shell 1, the side atmosphere module 4 can enlarge the side wall shape of the light cutting hole 411 and irradiate to the second inner side wall 103, and the atmosphere light spot formed by the side atmosphere module can form a clear cutoff line, so that a soft transition area is formed on the inner side wall on both sides, and the overall transition of the light is more natural and uniform. Further, when the sunny sky lamp realizes the blue sky simulation effect by the blue sky module 2 and the side atmosphere module 4, the blue sky simulation effect that can be achieved is closer to the real sky effect.

[0056] It should be noted that, asFigure 1 As shown, two mounting holes 12 are formed on the first inner side wall 102 of the shell 1, and the light cutting holes 411 of the light cutting plate 41 are also arranged symmetrically to ensure that the two inner side walls of the shell 1 can form a consistent side light atmosphere effect.

[0057] The opening size of the light cutting hole 411 gradually decreases from the middle of the first inner side wall 102 to the two side ends, so that the light spot of the side atmosphere module 4 irradiated to the second inner side wall 103 gradually decreases from the far end of the second inner side wall 103 to the direction of the first inner side wall 102, and forms a light-dark transition on the second inner side wall 103, thereby further ensuring that the side light atmosphere effect presented by the sunny sky lamp is more realistic and natural.

[0058] Specifically, as shown in Figure 6 The lower edge of the light cutting hole 411 is formed with a horizontal edge 412 and an inclined edge 413, and the included angle between the horizontal edge 412 and the inclined edge 413 is 130°-150°, preferably 141.4°, to ensure that the opening size of the light cutting hole 411 gradually decreases in a certain direction, and the edge of the light cutting hole 411 cuts the light spot edge more sharply, ensuring that the side atmosphere module 4 forms a light-dark transition on the inner side wall, and the side light atmosphere effect of the sunny sky lamp is more natural.

[0059] Specifically, as shown in Figure 4 and Figure 6 The side atmosphere module 4 includes an atmosphere light source 42, a convex lens 43, and a mounting box 44, the mounting box 44 is mounted in the mounting cavity 301, the light cutting plate 41 is arranged on the opening of the mounting box 44 towards the light emitting cavity 101, the atmosphere light source 42 is mounted on the bottom wall of the mounting box 44, and the convex lens 43 covers the atmosphere light source 42. The convex lens 43 can condense the light of the atmosphere light source 42 to reduce the light loss of the atmosphere light source 42, and the atmosphere light source 42, the convex lens 43, and the light cutting plate 41 form an integrated atmosphere module through the mounting box 44, and the installation position of the atmosphere light source 42 can be adjusted by adjusting the installation position of the mounting box 44 in the mounting cavity 301, so as to adjust the installation position of the atmosphere light source 42 according to the actual lighting condition, and ensure the lighting effect of the atmosphere light source 42 on the two inner side walls.

[0060] When the mounting box 44 is fixed in the mounting cavity 301, the atmosphere light source 42 is arranged in a staggered manner with the light cutting hole 411, so as to ensure that the light of the atmosphere light source 42 can be obliquely irradiated to the second inner side wall 103 from the light cutting hole 411, and further ensure the simulation incident effect of the atmosphere light source 42.

[0061] From the above enumerated embodiments of the utility model, it can be seen that the clear sky lamp of the utility model can provide a more profound and more stereoscopic blue sky effect by the blue sky module 2; meanwhile, the clear sky lamp can provide a blue sky simulation effect closer to the real sky by combining the side light atmosphere effect provided by the side atmosphere module 4; and the cooperation of the illumination light source 32 on the side of the shell 1 and the reflection cup 33 with a circular arc concave surface effectively enhances the light irradiation brightness of the side wall of the clear sky lamp, simultaneously forms a light spot with a regular and sharp boundary, realizes the light and shadow effect of simulating the sun penetrating through the window and irradiating to the indoor, and further guarantees the lighting effect of the clear sky lamp. The cooperation of the illumination module composed of the blue sky module 2, the side atmosphere module 4 and the illumination light source 32 and the reflection cup 33 makes the clear sky lamp be able to simulate the clear sky skylight and shadow effect.

[0062] The above is the preferred embodiment of the utility model, and it should be pointed out that for the ordinary skilled person in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements are also considered to be within the scope of protection of the utility model.
