[0002] With the improvement of living standards, people have higher and higher demands for lighting in different scenarios. Among them, lamps that can simulate outdoor natural ambient light are gradually favored by the market and are widely used in indoor lighting of homes, office buildings, shopping malls, stadiums, stations, airports, etc. Traditional blue sky lamps are generally composed of a light source and a pattern plate with blue sky and white clouds drawn on it.

[0047] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0048] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0049] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
[0050] See also Figure 1-3 As shown, a lamp 100 of a preferred embodiment of the present invention includes a first light source system 200, a second light source system 300 and a projection system 400. The first light source system 200 is configured to simulate sunlight at different time periods in nature. The second light source system 300 is arranged around the outside of the first light source system 200. The second light source system 300 is configured to simulate the effect of sunlight shining on the edge of the skylight. In addition, the second light source system 300 can also form a virtual image 303 in the first light source system 200. The projection system 400 is arranged on the side of the second light source system 300, and is configured to form a light spot on the ground or the wall.
[0051] The lamp 100 includes a shell 600, the shell 600 includes a bottom wall 610 and a frame 620 extending from the bottom wall 610 to a direction away from the bottom wall 610, a light outlet is formed between the bottom wall 610 and the frame 620, a first light outlet surface 201 of the first light source system 200 is arranged at the light outlet, the first light source system 200 includes a first light-emitting module 210 and a diffusion structure 220, the first light-emitting module 210 is fixedly connected to the bottom wall 610, the first light-emitting module 210 is configured to emit light to the diffusion structure 220, the diffusion structure 220 is installed in the frame 620, and the diffusion structure 220 covers the first light-emitting module 210, and the diffusion structure 220 is configured to even out the light emitted by the first light-emitting module 210.
[0052] In an optional embodiment, the first light source system 200 is a ceiling lamp, including a chassis, a mask, and a first light-emitting module 210, and the first light-emitting module 210 is a full-spectrum LED chip that can simulate the spectrum of daylight. In other embodiments, the first light-emitting module 210 can also be a conventional white light source, and nanoparticles are added to the diffusion structure 220 of the first light source system 200 to form Rayleigh scattering, so that the first light-emitting surface 201 appears blue like the sky. The present invention is not limited to this.
[0053] See also Figure 2-5 As shown, in a preferred embodiment of the invention, the first light source system 200 includes a first light emitting module 210 and a diffusion structure 220. The first light emitting module 210 includes a first substrate 211 and a plurality of light emitting modules 212. The first substrate 211 is fixedly connected to the bottom wall 610. The light emitting modules 212 are installed on a side of the first substrate 211 away from the bottom wall 610 and are electrically connected through the first substrate 211.
[0054] The light emitting module 212 includes at least two light emitting units, which can emit light of at least two spectra. The at least two light emitting units are staggered, and adjacent light emitting units of the same type are inverted.
[0055] See also Figure 5As shown, in a preferred embodiment, each light-emitting module 212 on the first light-emitting module 210 includes a first light-emitting unit 2121 and a second light-emitting unit 2122, wherein the first light-emitting unit 2121 and the second light-emitting unit 2122 are staggered, and two adjacent first light-emitting units 2121 / second light-emitting units 2122 are inverted. The first light-emitting unit 2121 includes any two of the four different colors of light-emitting elements, and the second light-emitting unit 2122 includes the remaining two colors of the four different colors of light-emitting elements. From left to right in a single light-emitting module are the first light-emitting unit 2121, the second light-emitting unit 2122, the first light-emitting unit 2121 and the second light-emitting unit 2122. The first light-emitting unit 2121 and the second light-emitting unit 2122 are staggered, while the adjacent first light-emitting units 2121 or the second light-emitting units 2122 are inverted. Different lighting effects can be achieved through these four different colors of light-emitting elements, and the staggered distribution of different types of light-emitting units and the inverted distribution of the same type of light-emitting units make the light color emitted by the first light source system 200 more uniform, which can simulate the color of sunlight at different times and achieve a dynamic effect of light.
[0056] In this embodiment, each light emitting module includes two first light emitting units 2121 and two second light emitting units 2122. In other embodiments, the number of first light emitting units 2121 and second light emitting units 2122 included in the light emitting module 212 may be greater, and the present invention is not limited to this.
[0057] A light source lens (not shown) is also mounted on the light-emitting unit of the light-emitting module. In the present embodiment, a light source lens is mounted on each light-emitting unit, that is, the light source lens and the light-emitting unit are arranged one by one. With such an arrangement, the light emitted by the light-emitting unit can be concentrated to the center of the light source lens and then emitted outward, thereby avoiding interference between the light rays. In other embodiments, the light source lens can also be a two-in-one, four-in-one or other multi-in-one lens, so that a single light source lens can cover more light-emitting units, or it can be a light source lens that covers the entire light-emitting unit, which can reduce the number of light source lenses and make production and assembly more convenient and quick.
[0058] In this embodiment, the light-emitting units are arranged in a circular shape on the first substrate 211. Specifically, they are arranged in a plurality of concentric circles, and the number of light-emitting units in each circle is a multiple of 6, 7 or 8. The number of light-emitting units in each concentric circle is determined according to the voltage of the light-emitting unit and the voltage of the driving power supply. In this embodiment, the voltage of the lamp bead 422 is 3V, and the voltage of the driving power supply is 24V, so a string of 8 is adopted, that is, the number of light-emitting units in each concentric circle is a multiple of 8.
[0059] In this embodiment, there are a total of Ri circles of light-emitting units on the first substrate 211, where i≥2, the number of light-emitting units in the R1th circle is N, the number of light-emitting units in the R2th circle is 2N, and the number of light-emitting units in the Rith circle is i*N. It is assumed that the R1th circle is 1 string, marked as 1_1, the R2th circle is 2 strings, marked as 2_1 and 2_2, and so on. The Rith circle is marked as i_1 to i_i, and there are a total of i*(i+1)*(i+2) / 6 strings, which is equivalent to being able to adjust i*(i+1)*(i+2) / 6 strings of picture beams. Since there are four light-emitting elements of different colors, various colors and brightness can be adjusted for 4*i*(i+1)*(i+2) / 6 areas. By accurately controlling the power of the light-emitting units in different areas through the control system, continuous changes in light from morning to night can be achieved.
[0060] In other embodiments, the light emitting units may be distributed on the first substrate 211 in other shapes such as a U-shape, and the present invention is not limited thereto.
[0061] The first light source system 200 also includes an inner frame 250 and a diffusion structure 220. The inner frame 250 is sleeved in the frame 720. The diffusion structure 220 is fixedly connected to one end of the inner frame 250 away from the first light-emitting module 210. The light emitted by the light-emitting unit in the first light-emitting module 210 passes through the diffusion structure 220. The diffusion structure 220 diffuses the light and divides the line light source or point light source into a uniform surface light source. In this embodiment, the diffusion structure 220 is a diffusion plate, the transmittance of the diffusion plate reaches 40%-65%, and the thickness of the diffusion plate is about 3mm.
[0062] The diffuser can effectively eliminate the granularity of the light emitted from the first light-emitting module 210 and has the function of diffusing light, that is, the light will be scattered on its surface, and the light will be spread softly and evenly. After the light is diffused by the diffuser, the irradiation area is larger, the light uniformity is better, and the chromaticity is stable.
[0063] In some other embodiments, the diffusion structure 220 may also be a microstructured structural member, which also covers the light-emitting module and can also play a good light-homogenizing role, which is not limited in the present invention.
[0064] In some embodiments, the first light source system 200 also includes a transparent plate 240, which is fixedly connected to one end of the inner frame 250 away from the first light-emitting module 210, and the transparent plate 240 is located on the side of the first light-emitting surface 201 away from the first light-emitting module 210, and the side of the transparent plate 240 away from the first light-emitting surface 201 is a mirror surface. At least part of the light emitted by the second light source system 300 is projected onto the transparent plate 240 after passing through the second light-emitting surface 301, and is reflected by the transparent plate 240 to form a virtual image 303 of the second light-emitting surface 301, so as to simulate the window shadow effect formed on the window when one side of the window is illuminated by sunlight, so that it appears to the human eye to have a sense of depth and transparency.
[0065] The reflectivity of the mirror surface of the transparent plate 240 to light is greater than the transmittance to light, so that external light can be limited from entering the transparent plate 240 from the light-emitting surface. Optionally, the material of the transparent plate 240 can be an inorganic material, and the inorganic material can be quartz glass. The transparent plate 240 can also be made of an organic material, and the organic material can be a polymer transparent material such as organic glass, which is not limited in the present invention.
[0066] In some embodiments, a thin unidirectional film layer, such as tin, silver or aluminum, is plated on the light-emitting surface of the transparent plate 240 by a crystal plating process to form a unidirectional film layer. The crystal plating process can make the unidirectional film layer have a relatively high smoothness. In other embodiments, the transparent plate 240 can be selected according to actual conditions, and there is no limitation here. The thickness of the unidirectional film layer can be adjusted according to actual conditions. When the thickness of the unidirectional film layer increases, its reflectivity and transmittance will change, and the reflectivity is higher than the transmittance to achieve the effect of one-way perspective.
[0067] By controlling the brightness changes of light-emitting units in different areas, different lighting effects such as morning glow and evening glow can be achieved.
[0068] The second light source system 300 is detachably connected to the lamp 100, and the second light source system 300 is arranged between the frame 620 and the first light source system 200, and is arranged around the first light emitting surface 201 of the first light source system 200. The second light source system 300 extends along the light emitting direction of the first light emitting module 210, and the second light source system 300 has a second light emitting surface 301 attached to the side of the frame 620 close to the first light emitting surface 201. The second light source system 300 also includes a second light emitting module 310, and the second light emitting module 310 is located between the second light emitting surface 301 and the frame 620 in the horizontal direction. The light emitted by the second light emitting module 310 passes through the second light emitting surface 301 and is emitted in a direction away from the frame 620. The light emitted from the second light emitting surface 301 and the first light emitting surface 201 intersect, and at the same time, the second light emitting surface 301 emits light at an angle downward to avoid the light emitted through the second light emitting surface 301 from irradiating the non-light emitting surface 302 of the second light source system 300. The angle between the light emitted from the first light emitting surface and the light emitted from the second light emitting surface is greater than or equal to 90°. The second light source system 300 is different from the conventional ambient light in that it emits light only toward the inner side of the lamp 100. In this embodiment, the frame 620 is made of an opaque material, thereby creating a sunlight entering and illuminating the window edge, visually forming a light-transmitting window effect.
[0069] In some embodiments, no additional light-emitting module is provided in the second light source system 300 , and the second light-emitting surface 301 is formed by directly reflecting the light emitted from the first light-emitting surface 201 .
[0070] The second light source system 300 further includes a non-light emitting surface 302, which is also disposed away from the frame 620, and a light / shadow transition zone 304 is formed between the non-light emitting surface 302 and the second light emitting surface 301. Fig.18 As shown, to simulate sunlight entering from one side, illuminating one side of the window and forming a dark side on the other side of the window, so that the display effect is more realistic, the second light-emitting surface 301 is circumferentially connected to the non-light-emitting surface 302, and together surround the outer periphery of the first light-emitting surface 201 to form an annular surface, and the light / shadow transition zone 304 is located at the junction of the second light-emitting surface 301 and the non-light-emitting surface 302. The function of the light / shadow transition zone 304 is to form a light-dark boundary area between the second light-emitting surface 301 and the non-light-emitting surface 302, which can be a continuously changing area from light to dark, or it can be an obvious dividing line.
[0071] The angle between the light emitted from the first light emitting surface 201 and the light emitted from the second light emitting surface 301 is greater than or equal to 90°. This arrangement can prevent the light from the first light emitting surface 201 from irradiating the non-light emitting surface 302 .
[0072] The second light source system 300 includes a second substrate 311 surrounding the first light emitting surface 201 and a light-emitting component 312 arranged on the second substrate 311. The second substrate 311 includes a light-emitting area arranged close to the second light emitting surface 301 and a non-light-emitting area arranged away from the second light emitting surface 301, so as to form an illuminated second light emitting surface 301 and an unilluminated non-light emitting surface 302 on the periphery of the first light emitting surface 201. The light-emitting component 312 is provided on the light-emitting area of the second substrate 311, and the light-emitting component 312 may not be provided in the non-light emitting area.
[0073] In some embodiments, the second light source system 300 also includes a shading member 324 facing away from the second light emitting surface 301, and the second light-emitting module 310 and the shading member 324 together surround the first light emitting surface 201 on one side close to the frame 620 to form an illuminated second light emitting surface 301 and an unilluminated non-light emitting surface 302 on the periphery of the first light emitting surface 201.
[0074] The second light source system 300 can be configured as a whole to rotate relative to the first light source system 200 , and the second light source system 300 can be driven to rotate by a micromotor disposed in the lamp 100 to better simulate the effect of the sun rising in the east and setting in the west.
[0075] The second light source system 300 is described below through three specific embodiments, but the present invention should not be limited thereto.
[0076] Embodiment 1
[0077] like Figure 2-3 and Figure 6 As shown, in this embodiment, the light emission direction of the light source module 310 is the same as the light emission direction of the first light-emitting module 210. The second light source system 300 includes a light source module 310 and a light guide assembly 320. The light guide assembly 320 includes a light distribution member 322 and a light output member 321. The light distribution member 322 is arranged below the light source module 310. The light source module 310 emits light toward the light distribution member 322 (i.e., the light source module 310 emits light directly). The light distribution member 322 is configured to refract the light emitted from the light source module 310. The light output member 321 is located on the side of the light distribution member 322 away from the frame 620. After being refracted by the light distribution member 322, the light emitted from the light distribution member 322 is then emitted toward the side away from the frame 620 through the light output member 321. The light distribution member 322 can control the emission angle of the light, so that the light is emitted at a small angle, with a long mapping distance and stronger transparency.
[0078] In some embodiments, one end of the light emitting member 321 away from the first light source system 200 is tilted toward the frame 620 by 5° to 30°, so that the light emitted from the second light emitting surface 301 has a wider irradiation range.
[0079] In this embodiment, the light distribution member 322 is a light guide plate, and the materials of the light distribution member 322 and the light output member 321 are transparent optical materials such as PMMA and PC. In other embodiments, the light distribution member 322 can also be an optical element of other structures or other materials, which is not limited by the present invention.
[0080] like Fig.10 As shown, in some embodiments, the light distribution element 322 is a lens, or Fig.12 As shown, in some embodiments, the light distribution component 322 is a reflective cup, the lens or the reflective cup is located in the light emission direction of the light source module 310, the lens or the reflective cup covers the light emitting component 312, and the light emitted by the light emitting component 312 is refracted by the lens or the reflective cup, and part of the light is emitted toward the light emitting component 321, and part of the light is emitted toward the frame 620. A reflective component 323 is provided on the side of the frame 620 close to the light emitting component 321 to reflect the light emitted to this part, and the light reflected by the reflective component 232 is emitted toward the light emitting component 321.
[0081] like Fig.11 As shown, in some embodiments, the light distribution element 322 is a polarized lens, or as shown in FIG. Fig.13 As shown, in some embodiments, the light distribution component 322 is an eccentric reflective cup, and the polarized lens or the eccentric reflective cup covers the light emitting component 312. After the light emitted by the light emitting component 312 is refracted by the polarized lens or the eccentric reflective cup, all of the light is emitted into the light emitting component 321 in a direction away from the frame 620. By using the polarized lens and the eccentric reflective cup, there is no need to set up the reflective component 323, and the structure is simpler.
[0082] like Fig.12 As shown, in some embodiments, when the light distribution component 322 is a reflective cup, a prism sheet 326 is covered on one end of the reflective cup away from the light source module 310. The prism sheet 326 is configured to refract part of the light emitted by the light-emitting module 310 that has not been refracted by the reflective cup, so that the part of the light is refracted by the prism sheet and then emitted toward the light output component 321 or toward the reflective component 323 on the frame 620, thereby improving the utilization rate of the light emitted by the light source module 310.
[0083] In some other embodiments, the light emitted by the light source module 310 may also be emitted vertically upward into the light guide assembly 320 , which is not limited in the present invention.
[0084] like Figure 6As shown, the light source module 310 includes a light source substrate 311 and a light-emitting component 312 installed on a partial area of the light source substrate 311. When the light-emitting component 312 on the light source module 310 emits light outward, the area of the light guide component 320 corresponding to the light-emitting component 312 on the light source substrate 311 is in a bright light state (i.e., the second light-emitting surface 301 of the second light source system 300), and the area of the light guide component 320 that does not correspond to the light-emitting component 312 on the light source substrate 311 is in a dark light state (i.e., the non-light-emitting surface 302 of the second light source system 300), so as to simulate the effect of illuminating the edge of one side of the window when sunlight shines through the window into the room.
[0085] In some other embodiments, light-emitting components 312 may be installed in all areas on the light source substrate 311. By controlling the working state of the light-emitting components 312 in different areas and realizing the change of the light source by lighting different positions, the conversion of the bright light area and the dark light area on the light-emitting component can be realized, simulating the effect of sunlight irradiating the edge of the skylight at different angles at different time periods of the day, and realizing sunrise and sunset. In this embodiment, the frame 620 is made of semi-transparent or translucent material. By controlling the different luminous colors of the light-emitting components 312 in different areas, a rainbow effect can be formed through the frame 620, thereby enhancing the visual experience of the lamp 100.
[0086] The light emitted after passing through the light distribution member 322 will pass through the light emitting member 321 . The light emitting member 321 can eliminate the granularity of the light emitted by the light source module 310 . Meanwhile, the light emitted after passing through the light emitting member 321 will be more uniform.
[0087] A reflective member 323 is attached to the side of the light distribution member 322 away from the light emitting member 321 or to the side of the frame 620 close to the light emitting member 321 to reflect the light directed to the area back so that the light is emitted toward the light emitting member 321, thereby improving the light concentration.
[0088] The portion of the light emitting element 321 that is not covered by the light distribution element 322 is covered with a shading element 324. The shading element 324 arranged here can prevent light from leaking out of this area on the light emitting element 321, so as to ensure that this area on the light emitting element 321 is in a dark state, simulating the effect of real sunlight shining on the edge of a window or a skylight.
[0089] In some other embodiments, the shading member 324 can rotate around the light distribution member 322. When all areas on the light source substrate 311 are installed with light-emitting members 312, the light-shielding member 324 can be rotated to realize the change of the bright area and the dark area on the light output member 321.
[0090] The height of the shading member 324 can be adjusted according to actual conditions by means of an elastic member provided in cooperation with a micro motor.
[0091] Embodiment 2
[0092] like Figure 7-8 As shown, in the present embodiment, the light emission direction of the light source module 310' intersects with the light emission direction of the first light-emitting module 210, the second light source system 300 includes a light emitting member 321, the light emitting member 321 is arranged between the frame 620 and the light emitting surface 201, and exceeds the light emitting surface 201 along the extension direction of the frame 620, the light source module 310' is arranged on the side of the light emitting member 321 facing the frame 620, the light source module 310' includes a ring-shaped light source substrate 311' and a light-emitting member 312 installed on the inner side of the substrate, the light source module 310' emits light in the direction of the light emitting member 321, and the emitted light is directly incident into the light emitting member 321 from the side of the light emitting member 321.
[0093] The second light source system 300' also includes a light-guiding lens 325, which is located between the light-emitting element 321 and the light source module 310'. The light-guiding lens 325 is connected to the inner side of the light source substrate 311' and covers the light-emitting element 312. The light emitted by the light-emitting element 312 is incident on the light-incident surface of the light-guiding lens 325, is refracted on the light-incident surface, enters the light-guiding lens 325 under the condition that Snell's law is satisfied, and then is refracted on the light-emitting surface. After being emitted from the light-guiding lens 325, the light is emitted through the light-emitting element 321 to achieve uniform emission of the light.
[0094] In this embodiment, the light source substrate 311 ′ may be made of a flexible printed circuit (FPC). In other embodiments, the light source substrate 311 ′ may also be made of other materials.
[0095] Preferably, the light emitting element 321 is made of transparent optical materials such as PMMA and PC.
[0096] In some other embodiments, it can also be arranged that all areas on the light source substrate 311' are installed with light-emitting components 312, and the light source substrate 311' is divided into multiple light-emitting areas, each light-emitting area includes multiple light-emitting components 312, and each light-emitting area can be individually controlled for lighting. By controlling the working state of different light-emitting areas, the conversion between the bright area and the dark area on the light-emitting component 321 can be realized, simulating the effect of sunlight shining on the edge of the skylight at different angles at different time periods of the day.
[0097] In some other embodiments, when the entire area of the light source substrate 311' is installed with the light emitting member 312, a shading member 324 may be attached to a partial area of the light emitting member 321 to prevent light from leaking out of the partial area of the light emitting member 321, so that the partial area of the light emitting member 321 is in a dark state, simulating the effect of real sunlight shining on the edge of a window or skylight. The shading plate can be rotated, and the light shading member 324 is rotated to change the bright light area on the light emitting member 321, simulating the effect of sunrise and sunset.
[0098] The overall structure of the second light source system 300 in this embodiment is simpler, and the light source module 310 ′ surrounds the outer side of the light emitting member 321 , so that the assembly is more convenient and quick.
[0099] Embodiment 3
[0100] In this embodiment, the structure of the second light source system 300 is basically the same as that of the first embodiment. The second light source system 300 only emits light to the side away from the frame 620. The light guide assembly 320 includes a light emitting member 321 and a light distribution member 322. The light source module 310 is fixedly connected to one end of the light emitting member 321. The light distribution member 322 is arranged around the outside of the light emitting member 321. The upper end surface of the light distribution member 322 covers the light emitting member 312 on the light source module 310. The difference is that a microstructure 3221 is provided in the second light emitting surface 301, and the microstructure 3221 enables light to be emitted at a large angle from the area of the second light emitting surface 301 where the microstructure 3221 is provided.
[0101] like Fig. 9 As shown, the light distribution component 322 in this embodiment is a light guide plate, and the fine structure 3221 is arranged on the light guide plate. The fine structure 3221 is located in the area of the light distribution component 322 far away from the light source module 310, and the light output component 321 is provided with an inverted fine structure. After the light is emitted from the light-emitting component 312, the fine structure 3221 on the light distribution component 322 destroys its total reflection, so that the light is emitted from the area where the fine structure 3221 is arranged on the light distribution component 322 at a large angle, and the light emitted from the light distribution component 322 enters the light output component 321 with the inverted fine structure. The inverted fine structure 3221 is used to allow part of the light to be emitted at a small angle to the transparent plate 240 and to form a transparent virtual image 303 through reflection.
[0102] Among them, the angles of the backlight surface and the light-facing surface of the fine structure 3221 on the light distribution component 322 are both less than 6 degrees. At the same time, the angle changes with the distance between the light-emitting component 312 and the light-entering side of the light distribution component 322, and the depth of the V-groove also changes. For the light-facing surface less than 6 degrees, after the light enters from the light-entering side, the angle of the light coming out from the light-emitting surface is 165 degrees to 175 degrees. The fine structure 3221 on the light-emitting side compresses the light to within 30 degrees toward the center. The light coming out at 165 degrees to 175 degrees can be emitted at a small angle through the inverted V prism on the light-emitting component 321, and the angle is less than 10 degrees. The uniformity of the light-emitting surface of the light distribution component 322 can be adjusted by adjusting the angles of the light-facing surface and the backlight surface and the depth of the V-groove.
[0103] Preferably, the angles of the backlight surface and the light-facing surface of the V-prism in the light distribution element 322 are both between 0.25 degrees and 0.75 degrees, and the vertex angle of the inverted V-prism in the light output element 321 is between 55 degrees and 70 degrees.
[0104] A reflective element 323 is covered on one side of the light distribution element 322 away from the light emitting element 321 to reflect the light emitted to the area inside the light distribution element 322 so that the light in the light distribution element 322 is emitted toward the light emitting element 321 .
[0105] like Fig.14 As shown, the lamp 100 is further provided with a side projection device 330, which is arranged between the frame 620 and the first light source system 200, and is configured to project a sun-like light spot, which is projected by the side projection device 330 into the mirror surface of the transparent plate 240, and then reflects on the mirror surface and then projects outward, so that a virtual sun spot is formed on the first light-emitting surface 201, and the human eye can see the scene illuminated by the sun through the transparent plate 240, so that the display effect of the lamp 100 is more realistic. The human eye can see the reflected virtual image on the first light-emitting surface 201, so that the display effect of the lamp 100 is more realistic.
[0106] The lamp 100 also includes one or more reflection devices 340, which are arranged in the light emitting direction of the side projection device 330. The light projected by the side projection device 330 is reflected once or multiple times by the reflection device 340 and then enters the mirror surface of the transparent plate 240. In this embodiment, the reflection device 340 is a reflector, which can be a plane, spherical, aspherical or free-form surface. When the reflector is a spherical or aspherical surface, the light spot projected by the side projection device 330 can be enlarged or reduced. The reflector with a free-form surface can not only enlarge or reduce the light spot, but also eliminate aberration problems such as distortion and astigmatism. At the same time, it also plays a role in changing the image distance, making the sun seen by the human eye farther away and increasing the sense of reality.
[0107] The side projection device 330 includes a projection lamp bead and a convex lens, wherein the projection lamp bead is a multi-color lamp bead to simulate the color temperature of the sun at different times, and the convex lens is a Fresnel lens or a compound eye lens to focus the light emitted by the projection lamp bead and obtain a uniform light spot.
[0108] The lamp 100 also includes a projection system 400, which is disposed between the frame 620 and the second light source system 300 and is at least partially exposed from the frame 620. The projection system 400 is configured to project simulated sunlight spots on a wall or the ground, including circular spots, elliptical spots or quadrilateral light panels, etc., similar to the projection produced by sunlight passing through a window.
[0109] The projection system 400 includes a plurality of projection devices 410. In this embodiment, two projection devices 410 are provided. The two projection devices 410 are each movably connected to the frame 620 of the lamp 100 through a connecting member. The projection devices 410 can rotate relative to the frame 620. Figure 15-11 As shown, the projection device 410 includes a light-emitting component 420, a lens barrel component 450 and a lens component 430. The light-emitting component 420 includes an aluminum substrate 421 and a lamp bead 422 mounted on the aluminum substrate 421. An aperture 440 is provided on the outer sleeve of the lamp bead 422. The aperture 440 abuts against the aluminum substrate 421. The aperture 440 is configured to control the intensity and shape of the light beam emitted by the lamp bead 422. A first lens 431 is connected to the end of the aperture 440 away from the lamp bead 422. The first lens 431 is configured to form a light spot. A lens 431 is provided on the outer sleeve of the aperture 440 and the first lens 431. The first lens barrel 451 and the second lens barrel 452 are screwed together with one end of the first lens barrel 451 away from the first lens 431, the second lens 432 is embedded in one side of the second lens barrel 452 close to the first lens barrel 451, the end of the second lens barrel 452 away from the first lens barrel 451 is screwed together with the third lens barrel 453, the end of the third lens barrel 453 away from the second lens barrel 452 is embedded with the third lens 433, the second lens 432 and the third lens 433 are configured to perform imaging, and the focal length is adjusted by utilizing the first lens barrel 451, the second lens barrel 452 and the third lens barrel 453.
[0110] The first lens 431 and the second lens 432 are plastic lenses, and the third lens 433 is a glass lens. The plastic lens is lighter, which is beneficial to the lightweight of the overall structure, while the glass lens can ensure a higher light transmittance.
[0111] In this embodiment, the lamp bead 422 is an LED lamp bead. In other embodiments, it can also be other types of lamp beads, and the present invention is not limited to this.
[0112] like Fig.17As shown, the projection direction of the projection system 400 is consistent with the direction of the second light emitting surface 301, and a light spot is projected on the wall on one side of the partial area to simulate the projection of the real sunlight through the window on the wall.
[0113] The lamp 100 further includes a control system, which controls the operation of the first light source system 200, the second light source system 300 and the projection system 400 to achieve lighting effects for various scenes.
[0114] The mounting system 500 includes a mounting bracket, which is fixedly connected to the bottom wall 610, and the lamp 100 is fixedly connected to the mounting surface through the mounting bracket. In this embodiment, the mounting system 500 is a rack-type structure, and in other embodiments, it can also be a quick-connect structure, which is not limited by the present invention.
[0115] In summary, the first light source system 200 in the lamp 100 of the present invention can simulate effects similar to the blue sky, sunset, morning light and blue sky and white clouds, and the second light source system 300 simulates the effect of sunlight shining on the edge of the window, making the lighting effect of the lamp 100 more realistic. The second light source system 300 can also form a virtual image 303 on the transparent plate 240 set therein, producing a window shadow effect similar to sunlight shining on the edge of the window or skylight, thereby forming a sense of space, depth and layering, and the projection system 400 can provide a light spot similar to sunlight projected onto the ground or wall through a window or skylight, and the shape of the light spot changes according to the overall shape of the lamp 100, which can achieve multi-scene applications.
[0116] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
