It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or otherwise described herein.

Referring to fig. 1, an embodiment of the present application proposes a lamp simulating sunlight. The sunlight-simulating lamp 10 includes, for example: the lamp comprises a lamp frame 102, a light-transmitting plate 105, a first light source assembly 110, a second light source assembly 120, a specular reflection assembly 103 and a diffuse reflection assembly 104.

The lamp frame 102 is, for example, formed with a first accommodation space 1021 therein, wherein the first accommodation space 1021 includes, for example, a first corner 11, a second corner 12, a third corner 13, and a fourth corner 14 in the lamp frame 102. A first opening 101 is provided in the bottom surface of the lamp frame 102 adjacent to the first corner 11 and the second corner 12, and the first opening 101 is located between the first corner 11 and the second corner 12. The light-transmitting plate 105 is disposed on the bottom surface of the lamp frame 102 and covers the first opening 101. The first light source assembly 110 is disposed at a first corner 11 in the first accommodation space 1021. The second light source assembly 120 is disposed at the second corner 12 in the first accommodation space 1021, and the second light source assembly 120 is disposed opposite to the first light source assembly 110. The specular reflection component 103 is disposed at the third angle 13 in the first accommodation space 1021 and corresponds to the first light source component 110. The diffuse reflection assembly 104 is disposed at the fourth corner 14 in the first accommodation space 1021 and corresponds to the second light source assembly 120. The first light beam a emitted from the first light source assembly 110 is reflected by the specular reflection assembly 103 and transmitted through the light-transmitting plate 105. The second light source assembly 120 emits a second light beam B, which is reflected by the diffuse reflection assembly 104 onto the light-transmitting plate 105.

Referring to fig. 2, a schematic perspective view of a lamp simulating sunlight according to an embodiment of the present application is shown. Specifically, the lamp frame 102 is, for example, a frame-like member with a hollow interior, and has a square shape, for example. The lamp frame 102 may be made of metal, preferably aluminum, and has strong supporting performance and is not easy to deform. The light-transmitting plate 105 is correspondingly covered on the first opening 101 to form a light-transmitting area, and the specific shape of the light-transmitting area can be determined according to the shape of the skylight or the needs of a user so as to match the reflected and scattered light beams, thereby achieving the effect of simulating the skylight. The light-transmitting plate 105 is, for example, a blue light-transmitting plate, which may be, for example, rayleigh Li Guangban, and the plate of the rayleigh light plate is prepared from rayleigh scattering material master batch, and the plate is rayleigh-scattered based on the blue light spectrum under the irradiation of the light source, so that the effect of blue sky can be truly simulated by the corresponding lamp, wherein the plate is based on the principle that the blue light spectrum under the irradiation of the light source generates rayleigh scattering, and can be understood as being similar to the principle that the sunlight in reality is more obvious because the blue-violet light with higher frequency is scattered than the red light with lower frequency in the solar spectrum, and the blue light with the largest blue light energy is scattered under the strong scattering action of atmospheric molecules, so that the sky is the blue light with beautiful blue color. It should be noted that the rayleigh plate does not substantially absorb light in the visible range, and for a transmitted (directional non-diffuse, i.e. reflective) light source it does not change its direction and color, i.e. when the light source transmitted through the light-transmitting plate 105 is white, the resulting spot is also white. The rayleigh optical plate may adopt related technologies and schemes in the prior art, and will not be described herein.

The first light source assembly 110 is configured to emit light, which passes through a specific optical element to form a light beam with a specific shape, such as a first light beam a, and is projected onto the specular reflection assembly 103, and then the first light beam a is reflected by the specular reflection assembly 103 to the light-transmitting plate 105. Due to the property of the transparent plate 105, the first light beam a passes through the transparent plate 105 and is projected onto the ground or the wall, so that the light spot irradiated by the sunlight through the skylight can be simulated. The second light source component 120 is configured to emit light, where the light passes through a specific optical element to form a light beam with a specific shape, such as the second light beam B, and is projected onto the diffuse reflection component 104, and then the light beam is reflected by the diffuse reflection component 104, and the light beam is projected onto the light-transmitting plate 105, so that the light-transmitting plate 105 achieves a floodlighting effect, and visually achieves an effect of simulating a blue sky according to the material characteristics of the light-transmitting plate 105. Specifically, the specular reflection component 103 may include, for example, a specular reflection sheet 1031 having a smooth surface and a rotatable first bracket 1032 that connects the lamp frame 102 to fix the specular reflection sheet 1031, and the specular reflection sheet 1031 may totally reflect the light beam projected thereon. The diffuse reflecting member 104 may be understood as a diffuse reflecting plate 1041 having a rugged surface and a second holder 1042 connected to the lamp frame 102 to fix the diffuse reflecting plate, and the diffuse reflecting plate 1041 is used to disperse the projected light beam of a specific shape.

The number of the second openings 1141 is plural, and the plurality of second openings 1141 corresponds to the plurality of through holes 1181 on the first optical module set 118 one by one, wherein the preset shape of the second openings 1141 is set according to the shape of the light spot to be formed, so as to realize more realistic simulation of the shape of the light spot irradiated by the sunlight from the skylight.

Furthermore, referring to fig. 5, the luminaire 10 simulating sunlight further includes, for example: the light source module 130, the control unit 140 and the driving module 150, the power source module 130 is disposed on a side surface of the lamp frame 102 far away from the light-transmitting plate 105, the power source module 130 is electrically connected with the control unit 140 and the driving module 150, the control unit 140 is electrically connected with the driving module 150, the first light source module 110 and the second light source module 120, the driving module 150 is connected with the specular reflection module 103, and the driving module 150 is used for adjusting the inclination angle of the specular reflection module 103 under the control of the control unit 140.

Wherein the power supply assembly 130 provides power to the sunlight-simulating luminaire 10. The control unit 140 is, for example, a single-chip microcomputer control board, so as to control the lamp 10 simulating sunlight to perform certain functions, such as turning on and off the lamp. As shown in fig. 6, the driving assembly 150 includes, for example: the motor 151, the transmission shaft 152 connected to the motor 151, and the axle 153 fixedly connected to the first bracket 1032 of the specular reflection assembly 103 and used for cooperating with the transmission shaft 152 to rotate, wherein the transmission shaft 152 is, for example, a cylindrical gear, the axle 153 is, for example, a sector gear, the transmission shaft 152 is meshed with the gear of the axle 153, and when the control unit 140 controls the motor 151 to rotate, the transmission shaft 152 is driven to rotate so as to drive the axle 153 to rotate, so as to change the inclination angle of the specular reflection assembly 103. Specifically, the inclination angle here is, for example, an angle between the specular reflection sheet 1031 of the specular reflection component 103 and a side wall adjacent to the first corner and the third corner in the lamp frame 102, so that the light spot projected by the lamp 10 can move smoothly and continuously, and truly restores the motion track of the sun in nature along with the change of time. In addition, by using this method, the distance and angular velocity parameters of the spot movement can be automatically adjusted in better combination with the program control of the control unit 140.

Further, the luminaire frame 102 includes, for example: adjacent the first corner 11 and the third corner 13 and connecting the first side wall of the bottom surface. The specular reflection sheet 1031 of the specular reflection component 103 forms a first included angle a with the first sidewall. In particular, the first angle a is for example an obtuse angle, which ranges from 92 to 122 °, preferably the first angle a is 107 °. The design of the angle range of the first angle a is 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 into a certain position range through the transparent plate 105. For example, to simulate the trajectory change of real sunlight according to time, so that the light spot moves to the corresponding position, the first included angle a is automatically or manually adjusted to 107 ° so that the light spot is located at the corresponding position. The angle of the included angle a can be set according to actual requirements, so that the light spot irradiates to the corresponding position.

The setting of the angle range of the first included angle a is to ensure that the outgoing first light beam a can be projected onto the specular reflection sheet 1031, and 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 a sunlight light spot.

Further, the luminaire frame 102 includes: adjacent the second corner 12 and fourth corner 14 and connecting the second side wall of the bottom surface. The diffuse mirror plate 1041 of the diffuse reflecting assembly 104 forms a second angle b with the second sidewall. In particular, the second angle b is for example an obtuse angle, which ranges from 102 to 132 °, preferably the second angle b is 107 °. The design of the angle range of the second included angle B is based on the diffuse mirror 1041 being capable of receiving the projection of the second light beam B and scattering the scattered light beam onto the light-transmitting plate 105. For example, to simulate a more realistic rainy sky blue sky effect, the second angle b is adjusted to 117 °. Of course, the angle of the included angle b can be set according to actual requirements, so that a more real blue sky effect can be achieved visually.

For example, referring to fig. 1 and 7, when the lamp is used, 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 condensation projection through the first condensation lens group, the first diaphragm 114 and the first light projecting lens 116 in the first optical module assembly 118, and performs total reflection on the mirror reflection sheet 1031 on the mirror reflection assembly 103, and is reflected to the ground or the wall through the light transmission plate 105 to form a trapezoid light spot so as to achieve the light spot effect of simulating sunlight irradiation; meanwhile, the second light source 211 sequentially performs condensation projection through the second condensing lens group, the second diaphragm 214 and the second light projecting lens 216 in the second optical module set 118, and projects 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 effect enables the light-transmitting plate 105 to generate blue floodlight in vision, so as to achieve the effect of simulating blue sky. In the use process, the user can also control the motor in the driving assembly 150 through the control unit 140 in a manual or automatic mode to drive the wheel axle 153 to rotate, so as to change the included angle a between the specular reflection assembly 103 and the lamp frame 102, change the light spot irradiation position, and further simulate the track movement of the sun, so as to simulate the natural sunlight movement more realistically. Through the cooperation of the simulated sunlight and the blue sky, layering and stereoscopic impression of light can be increased, so that the matching effect of the blue sky and the sunlight is truly shown, and the experience of a user is improved.

In summary, in the sunlight-simulating lamp 10 disclosed in the present embodiment, the specific structures and the 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 can visually increase the layering and stereoscopic impression of the light, so as to truly show the matching effect of the blue sky and the sunlight, and improve the experience of the user. The specific structural design of the first light source assembly 110 and the second light source assembly 120 can increase the light converging intensity, reduce the light waste, realize the preset beam shape through the specific structural design and improve the light emitting effect; through setting up the control unit 140, the drive assembly 150, but the inclination of automatically/manual regulation specular reflection subassembly 103 makes the light beam angle change to reach the facula position and change along with specular reflection piece 1031 angle change and produce the change, can realize simulating the motion trail of sun, further promoted the play light effect of lamps and lanterns, promoted user experience degree. By arranging the first protruding part at the first corner and the second protruding part at the second corner, the first light source assembly 110 and the second light source assembly 120 are mutually independent, so that the interference of light is avoided, and the light emitting effect is influenced.
