In particular, the first angle a is, for example, an obtuse angle in the range of 92-122 °, preferably 107 °. The angle range of the first included angle a is designed based on the fact that the specular reflection sheet 1031 can receive the projection of the first light beam a and project the reflected light beam to a certain position range through the transmission plate 105. For example, to simulate the trajectory change of the real sunlight according to the time, so as to move the light spot to the corresponding position, the first included angle a is automatically or manually adjusted to 107 ° so as to enable the light spot to be located at the corresponding position. Of course, the angle of the included angle a can be set according to actual requirements, so that the light spot irradiates to a corresponding position.

The angle range of the first included angle a is set to ensure that the emergent first light beam a can be projected onto the specular reflection sheet 1031, and is reflected by the specular reflection sheet 1031 to be projected onto the ground or the wall through the light-transmitting plate 105 to form a light spot, so as to visually simulate the sunlight light spot.

Further, the luminaire frame 102 comprises: a second sidewall adjacent the second corner 12 and the fourth corner 14 and connecting the bottom surfaces. A second angle b between the diffuse reflection sheet 1041 of the diffuse reflection assembly 104 and the second sidewall. Specifically, the second included angle b is, for example, an obtuse angle in the range of 102 ° and 132 °, and preferably, the second included angle b is 107 °. The angle range of the second included angle B is designed based on the diffuse reflection mirror 1041 being capable of receiving the projection of the second light beam B and scattering the scattered light beam onto the transparent plate 105. For example, to simulate a more realistic blue sky effect of a rainy weather, the second included angle b is adjusted to 117 °. Certainly, the angle of the included angle b can be set according to actual requirements, and a more real blue sky effect is achieved visually.

For example, referring to fig. 1 and 7, when the lamp is used, firstly, power is supplied through the power supply assembly 130, so that the first light source 111 in the first light source assembly 110 and the second light source 211 in the second light source assembly 120 respectively emit light, the first light source 111 sequentially performs light-gathering projection through the first light-gathering lens group, the first diaphragm 114 and the first light-projecting lens 116 in the first optical module assembly 118, projects the light onto the specular reflection sheet 1031 on the specular reflection assembly 103 for total reflection, and reflects the light onto the ground or a wall and forms a trapezoidal light spot through the light-transmitting plate 105, so as to achieve a light spot effect of simulating sunlight irradiation; meanwhile, the second light source 211 sequentially performs light condensing projection through the second light condensing lens set, the second diaphragm 214 and the second light projecting lens 216 in the second optical module assembly 118, and projects the light onto the diffuse reflection lens of the diffuse reflection assembly 104 to perform diffuse reflection onto the light-transmitting plate 105, and based on the characteristics of the light-transmitting plate 105, the diffuse reflection function enables the light-transmitting plate 105 to generate blue floodlight in vision, so as to achieve the effect of simulating a blue sky. In the using process, the user can also control the motor in the driving assembly 150 to drive the wheel shaft 153 to rotate in a manual or automatic manner through the control unit 140, so as to change the included angle a between the specular reflection assembly 103 and the lamp frame 102, so as to change the position irradiated by the light spot, and further simulate the trajectory movement of the sun, so as to simulate the natural sunlight movement more realistically. Through the cooperation of simulated sunlight and the blue sky, the layering sense and the third dimension of light can be increased to truly show the matching effect of the blue sky and sunlight, and the experience sense of a user is improved.

In summary, in the sunlight simulating lamp 10 disclosed in this embodiment, through the specific structures and optical path designs of the first light source assembly 110 and the specular reflection assembly 103, and the second light source assembly 120 and the diffuse reflection assembly 104, the layering sense and the stereoscopic sense of light can be visually increased, so that the matching effect of blue sky and sunlight is truly expressed, and the experience sense of a user is improved. Through the specific structural design of the first light source assembly 110 and the second light source assembly 120, the intensity of light convergence can be increased, the light waste is reduced, and the light emitting effect is improved by realizing the preset beam shape through the specific structural design; through setting up the control unit 140, drive assembly 150, can automatic/manual regulation specular reflection subassembly 103's inclination, make the beam angle change to reach the spot position and change along with specular reflection piece 1031 angle, can realize the motion trail of simulation sun, further promoted the light-emitting effect of lamps and lanterns, promote user experience degree. The first protruding portion is arranged at the first corner, and the second protruding portion is arranged at the second corner, so that the first light source assembly 110 and the second light source assembly 120 are independent of each other, interference of light is avoided, and the light emitting effect is influenced.
