[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0033] Here, it should be noted that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the drawings, while other details less related to the present invention are omitted.

[0034] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0035] Please refer to Figures 1 to 6 As shown, the lamp 100 of a preferred embodiment of the present invention includes a side - emitting device 200 and a surface - emitting device 300. The surface - emitting device 300 is configured to simulate sunlight at different times in nature. The side - emitting device 200 is disposed around the outside of the surface - emitting device 300. The side - emitting device 200 is configured to simulate the effect of sunlight shining on the edge of a skylight. In addition, the side - emitting device 200 can also form a virtual image 360 in the surface - emitting device 300 to simulate the window - shadow effect produced by the window ledge on the skylight glass. This lamp 100 can better restore the effect of real sunlight shining into the room through the skylight.

[0036] Refer to Figure 2As shown, the luminaire 100 further includes a bottom wall 110, which is fixedly connected to the installation surface. The side light-emitting device 200 includes a frame 210 extending in the vertical direction, a light source module 220, a control module, and a light-emitting member 230. One end of the frame 210 abuts against the bottom wall 110 and is disposed around the bottom wall 110. The light source module 220 is disposed inside the frame 210. The light source module 220 includes a plurality of light-emitting elements 222, and the plurality of light-emitting elements 222 are divided into a plurality of light source areas 223. The control module controls the working states of the respective light source areas 223, and the working states include a lighting state and an extinguished state. The light-emitting member 230 is located on the side of the light source module 220 facing away from the frame 210. Refer to Figure 6 As shown, the light emitted by the light source area 223 in the lighting state forms a bright area 231 on the light-emitting member 230, and the light source area 223 not in the lighting state forms a non-bright area 232 on the light-emitting member 230. The bright area 231 and the non-bright area 232 are circumferentially connected, and a clear light / shadow transition area 233 is formed between the bright area 231 and the non-bright area 232.

[0037] By controlling the control module to make the working states of some light source areas 223 be in the lighting state, the light-emitting elements 222 in the light source areas 223 in the lighting state emit light to form a bright area 231 on the light-emitting member 230, and a light / shadow transition area 233 is formed between the bright area 231 and the non-bright area 232, truly restoring the effect of sunlight obliquely irradiating on the window sill when it shines into the room through the skylight. By controlling the control module to make the light source areas 223 at different positions be in the lighting state, the position transformation of the bright area 231 and the non-bright area 232 is realized on the light-emitting member 230, simulating the effect of sunlight shining on the window sill through the skylight at different times, and realizing the effect of the sun rising in the east and setting in the west.

[0038] The control module includes a plurality of control units 250. The control units 250 are arranged in one-to-one correspondence with the light source areas 223. The control unit 250 controls the working state of the corresponding light source area 223, and the working states include a lighting state and an extinguished state. By using the plurality of control units 250 provided, precise control of each light source area 223 is achieved, and the position transformation of the bright area 231 and the non-bright area 232 is realized. At the same time, the control unit 250 can also control the brightness value and color of the light source area 223 in the lighting state to change, so as to present a more colorful lighting effect.

[0039] In this embodiment, the light source module 220 further includes a light source substrate 224. The light source substrate 224 is fixedly connected to the frame 210. The light-emitting elements 222 are arranged in an array on one side of the light source substrate 224 facing the light-emitting member 230. Each light-emitting element 222 includes at least two types of light-emitting chips with different colors. There are two types of light-emitting elements 222, and the colors of the light-emitting chips on each type of light-emitting element 222 are different. Through the mixing of the light emitted by the light-emitting chips of different colors on the light-emitting elements 222, the color of sunlight at different times is simulated, and the different light color effects of sunlight from morning to dusk are simulated, so that the restoration degree of the lamp 100 is higher, and the user experience is improved.

[0040] The sizes and shapes of the respective light source areas 223 are all the same, so that the uniformity of the bright area 231 formed on the light-emitting member 230 is better, and at the same time, the shape of the formed bright area 231 always remains the same at any time.

[0041] The light source areas 223 in the lighting state are continuously distributed. The boundary between any two adjacent light source areas 223 has a non-right-angle angle with the vertical direction, that is, the boundary is oblique. In this way, a clear light / shadow transition area 233 can be formed on the light-emitting member 230. Among the light source areas 223 in the lighting state, the brightness value of the light source area 223 near the light / shadow transition area 233 is lower than that of the light source area 223 far from the light / shadow transition area 233, so as to form a gradually dimming effect between the bright area 231 and the non-bright area 232, and the visual effect is better.

[0042] All the light source areas 223 on one side of the light / shadow transition area 233 are in the lighting state, and all the light source areas 223 on the other side of the light / shadow transition area 233 are in the extinguished state. When simulating sunlight shining into the room through the skylight, a part of the window edge of the skylight is illuminated, and the other part of the window edge is completely in a dark state.

[0043] In this embodiment, when the light-emitting elements 222 in the light source module 220 are in the lighting state for a long time, a large amount of heat will be generated. The light source substrate 224 is directly connected to the frame 210, which is convenient for dissipating heat from the light source module 220, so as to extend the service life of the light source module 220.

[0044] There is an air cavity 240 between the light source module 220 and the light-emitting member 230. By providing the air cavity 240, the optical path of the light emitted by the light-emitting elements 222 is increased, so as to avoid affecting the effect presented by the concept stock on the light-emitting member 230 due to uneven light mixing. The light emitted by the light-emitting elements 222 is mixed in the air cavity 240 and then enters the light-emitting member 230.

[0045] In this embodiment, multiple light-emitting chips on a single light-emitting element 222 are integrally packaged, which can reduce the thickness of the air cavity 240, thereby controlling the overall volume of the lamp 100 to be smaller and improving the aesthetics of the lamp 100.

[0046] The control unit 250 controls the brightness values of the light-emitting chips of each color in the corresponding light source area 223 to present the effects of sunlight at different times. In this embodiment, the control unit 250 is installed on the light source substrate 224, and the control unit 250 uses a control IC. In some other embodiments, other types of controllers can also be selected, and the present invention does not limit this.

[0047] In this embodiment, the light-emitting chips of the same color in each light source area 223 are connected in series, and the light-emitting chips of different colors are connected in parallel. The control unit 250 changes the brightness values of the light-emitting chips of each color by controlling the magnitude of the current value in each circuit, thereby simulating the effects of sunlight at different times, such as morning glow and evening glow.

[0048] The light-emitting element 222 includes a first light-emitting element 2221 and a second light-emitting element 2222. The first light-emitting element 2221 includes light-emitting chips of any two colors among red, blue, green, and white, and the second light-emitting element 2222 includes light-emitting chips of the other two colors different from those in the first light-emitting element 2221.

[0049] As Figure 5 shown, in this embodiment, the first light-emitting element 2221 includes light-emitting chips of two colors, red and green, and the second light-emitting element 2222 includes light-emitting chips of two colors, blue and white. The first light-emitting element 2221 and the second light-emitting element 2222 are arranged in an array on the light source substrate 224. Among them, in the horizontal direction, the types of the light-emitting elements 222 are the same, and in the vertical direction, the types of the light-emitting elements 222 are different. Different types of the light-emitting elements 222 are staggered. In this embodiment, that is, the first light-emitting element 2221 and the second light-emitting element 2222 are staggered. Staggering the first light-emitting element 2221 and the second light-emitting element 2222 in the vertical direction can make the uniformity of the light area 231 presented on the light-emitting member 230 better and avoid the situation of uneven color in local areas.

[0050] In some other embodiments, it can also be set that in the vertical direction, the types of the light-emitting elements 222 are the same, and in the horizontal direction, the types of the light-emitting elements 222 are different. Different types of the light-emitting elements 222 are staggered, which can also ensure good uniformity of the light area 231 presented on the light-emitting member 230.

[0051] In this embodiment, when the light-emitting element 222 is square or rectangular, the length of the longest side of the light-emitting element 222 is less than 3 mm. When the light-emitting element 222 is circular, the diameter of the light-emitting element 222 is less than 13 mm. When small-particle light-emitting elements 222 are used, the distance between the light-emitting elements 222 is as small as possible, so as to shorten the thickness of the air cavity 240. When the light source area 223 is in the illumination state, a clear light / shadow transition area 233 can be formed on the light-emitting member 230, thereby forming the boundary effect when the sun shines obliquely through the skylight on the window edge. The thickness of the air cavity 240 is D, and the row spacing of the light-emitting elements 222 is L, and D / L > 1.2, so that the light emitted by the light-emitting elements has enough travel distance in the air cavity 240 to ensure a good light mixing effect.

[0052] In this embodiment, the power of the light-emitting element 222 is ≥1 W to ensure a good light effect. In this embodiment, the light-emitting element 222 is an LED lamp bead. In other embodiments, it can also be other types of light-emitting chips, and the present invention does not limit this.

[0053] As Figure 5 shown, in this embodiment, each light source area 223 has an isosceles triangle contour and includes light-emitting chips of all colors. The light source area 223 with an isosceles triangle contour can make the bright area 231 presented on the light-emitting member 230 have a light / shadow transition area 233, and the light / shadow transition area 233 is a slant line, simulating the effect when the sun shines obliquely on the skylight edge. In some other embodiments, the light source area 223 can also have an isosceles trapezoid or non-right trapezoid contour.

[0054] In this embodiment, the material of the light-emitting member 230 is one of PMMA, PC, and PS. The material of the light-emitting member 230 includes a light diffusing agent, and the light emitted by the light source module 220 is scattered by the light-emitting member 230 and then emitted outward. The light diffusing agent added to the material of the light-emitting member 230 has the function of diffusing light, that is, light will be scattered in it and spread the light softly and evenly. The light is emitted outward after passing through the light-emitting member 230, and the light uniformity is better, and the chromaticity and color temperature are more stable.

[0055] Refer to Figures 2 to 4 shown, the surface light-emitting device 300 includes a light-emitting surface 350. The frame 210 of the side light-emitting device 200 extends downward from the light-emitting surface 350. A transparent plate 330 is provided on one side of the light-emitting surface 350 close to the light-emitting member 230. The side of the transparent plate 330 close to the light-emitting member 230 is a mirror surface. The transparent plate 330 is configured to reflect part of the light emitted outward through the light-emitting member 230 to form a virtual image 360 of the light-emitting member 230. To simulate the window shadow effect formed on the skylight when one side of the skylight is illuminated by sunlight, making it look deep and transparent to the human eye.

[0056] The surface light-emitting device 300 further includes a surface light source component 310, an inner frame 340, and a diffusion structure 320. The inner frame 340 is sleeved in the frame 210. The surface light source component 310 is fixedly connected to one end of the inner frame 340 facing the bottom wall 110. The diffusion structure 320 is fixedly connected to one end of the inner frame 340 away from the surface light source component 310. The light emitted by the surface light source component 310 passes through the diffusion structure 320, and the diffusion structure 320 diffuses the light, separating the line light source or point light source into a uniform surface light source. The transparent plate 330 is located on the side of the diffusion structure 320 facing away from the surface light source component 310. The diffusion structure 320 and the transparent plate 330 together form a light-emitting surface 350.

[0057] The surface light-emitting device 300 can simulate effects similar to blue sky, sunset, morning light, and blue sky with white clouds. The color of the light emitted by the side light-emitting device 200 matches the simulated effect of the surface light-emitting device 300 to enhance the simulated effect and bring a better visual experience.

[0058] The light-emitting mode of the side light-emitting device 200 is different from that of a conventional atmosphere lamp. The side light-emitting device 200 only emits light to the inside of the lamp 100. In this embodiment, the frame 210 is made of a light-tight material, thus creating an effect of sunlight shining in and illuminating the window edge of the skylight, forming a light-transmitting window effect visually.

[0059] In summary, the surface light-emitting device 300 in the lamp 100 of the present invention can simulate effects similar to blue sky, sunset, morning light, and blue sky with white clouds. The side light-emitting device 200 simulates the effect of sunlight shining on the edge of the skylight, making the lighting effect of the lamp 100 more realistic. By controlling the control unit 250, part of the light source area 223 is in the lighting state, and the light-emitting elements 222 in the light source area 223 in the lighting state emit light to form a bright area 231 on the light-emitting member 230. A light / shadow transition area 233 is formed between the bright area 231 and the non-bright area 232 to truly restore the effect of sunlight obliquely shining on the window edge when sunlight shines into the house through the skylight. By controlling the control unit 250 to make different positions of the light source area 223 in the lighting state, the position transformation of the bright area 231 and the non-bright area 232 is realized on the light-emitting member 230, simulating the effect of sunlight shining on the skylight edge at different times, and realizing an effect similar to the sun rising in the east and setting in the west. The side light-emitting device 200 can also form a virtual image 360 on the transparent plate 330 of the surface light-emitting device 300, generating a window shadow effect similar to sunlight shining on the skylight or the glass on the skylight edge, thereby forming a sense of space, depth, and hierarchy.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
