[0043] In some embodiments, the light-adjusting assembly 2 further comprises a mounting seat 5, and the light-reflecting cup 21 and / or the convex lens 22 are arranged on the mounting seat 5. The mounting seat 5 comprises a positioning hole 51 and a female buckle 52, the convex lens 22 is arranged above the positioning hole 51, the light-reflecting cup 21 is provided with a male buckle 211, and the light-reflecting cup 21 is fixed by clamping the male buckle 211 with the female buckle 52.

[0044] It should be noted that in the above manner, the mounting seat 5 can be fixed on the rotating seat 4 in advance by means of bolts or the like, and the bottom plate provided with the light-emitting assembly 1 is pressed tightly on the rotating seat 4 through the mounting seat 5. The mounting seat 5 is provided with a positioning hole 51, the light-emitting assembly 1 is located in the positioning hole 51, and the convex lens 22 is arranged above the positioning hole 51 to converge the light emitted by the light-emitting assembly 1. The light-reflecting cup 21 is arranged outside the convex lens 22 to further converge and collimate the light processed by the convex lens 22 before emitting.

[0045] Preferably, the reflector cup 21 includes an upper reflective surface 212 and a lower reflective surface 213, wherein the tilt angle of the upper reflective surface 212 is greater than that of the lower reflective surface 213.

[0046] Several light-emitting components 1, reflectors 21, and convex lenses 22 are arranged in a row on the rotating base 4 to form a linear lighting structure. This lighting structure can form a rectangular light spot on a wall or the ground. When the second light source illuminates the center of the wall, the angle between the reflector 21 and the blue sky module 200 is [degree]. Using this angle as a reference, the angle can be adjusted between 20° and 50° to accommodate different installation distances required by different customers. When the distance is too far, the adjustment angle of the second light source can be increased to ensure that the light spot remains on the wall and does not fall to the ground, thus affecting the overall effect. In this embodiment, the dimming component 2 includes both a reflector 21 and a convex lens 22. The blue sky cavity 101 and the lighting cavity 102 are independent cavities. The light-emitting component 1 includes a combination of several LED beads with different fixed color temperatures. When different color temperatures of light are required, the corresponding color temperature LED beads can be selectively illuminated. In other embodiments, the light-emitting component 1 can also be a single adjustable color temperature LED bead, which can generate light of different color temperatures by energizing different pins of the bead, simulating the light and shadow effect of sunlight shining through a window at different times. For example: Refer to Figure 6 In area A, during morning mode, the second light source angle is adjusted to 50 degrees, at which point the 4000K LED is illuminated; (Refer to...)

Three different modes can be adjusted according to customer preference.

[0047] According to the third embodiment of this utility model, the difference from the second embodiment is that the blue sky cavity 101 and the lighting cavity 102 have a connecting channel 106, and the reflector 21 has a light-transmitting hole 214 that can communicate with the connecting channel 106. In this embodiment, the second light source 105 not only emits light outward to produce a light spot similar to sunlight, but also emits light into the blue sky cavity 101 through the connecting channel 106 to produce an effect similar to sunset.

[0048] Since the light of the second light source 105 is strong, the diameter of the connecting channel 106 can be controlled to control the light output of a single connecting channel 106. Further, a diffusion plate 107 can be arranged at the connection between the connecting channel 106 and the blue sky cavity 101. The strong light is converted into soft light by the diffusion plate 107 and irradiated in the blue sky module 200 to form the effect of a blue sky with a red sunset.

[0049] Preferably, a plurality of the light emitting assemblies 1, the reflecting cups 21 and the convex lenses 22 are arranged in a row on the rotating seat 4 to form a linearly arranged lighting structure; the sub-light transmission hole 43 on the rotating seat 4, the light transmission hole 214 and the connecting channel 106 are in communication when the rotating seat 4 is at a predetermined angle. Based on the specific embodiments of the second embodiment, the light emitting assembly 1 can emit light of a corresponding color temperature according to the passage of time, cooperate with the rotation of the rotating seat 4, and also control the irradiation angle of the light to simulate the effect of the movement of the sun. On this basis, the light inlet of the connecting channel 106 is arranged at a predetermined position in this embodiment, so that the light transmission hole 214 and the connecting channel 106 are in communication when the rotating seat 4 is at a predetermined angle, and the light emitted by the second light source 105 enters the blue sky cavity 101 through the connecting channel 106. When the included angle between the reflecting cup 21 and the blue sky module 200 is 20 degrees, the light transmission hole 214 and the connecting channel 106 are in communication, that is, when the light irradiation simulates the evening, the light emitted by the second light source 105 starts to enter the blue sky cavity 101, and the sunset effect is realized by mechanical control. At other times, it is a normal blue sky effect. During the rotation of the rotating seat 4, the light transmission hole 214 and the connecting channel 106 also gradually align and misalign, and at this time the red light entering the blue sky cavity 101 also experiences a process from small to large and then disappears. The sunset effect with dynamics is cleverly realized by the design of the mechanical structure.

[0050] In combination Figure 7 As shown, preferably, the connecting channel 106 corresponds to the light emitting assembly 1 one by one, and the connecting channels 106 are arranged at an angle to each other in the horizontal direction, so that the light emitted from the connecting channels 106 is staggered with each other to form a sunset atmosphere with light and dark changes at different positions in the blue sky module 200, and the natural simulation effect of the blue sky lamp is improved.

[0051] The above is the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements are also considered to be within the protection scope of the present application.
