[0001] This application claims priority to Chinese patent applications with application date of November 23, 2023, application number 202311578574.2, invention name “Lamp” and application date of November 23, 2023, application number 202323178244.2, invention name “Lamp”. The entire contents of these patent applications are incorporated into this application by reference. Technical Field
[0002] The present application relates to the field of lighting, and in particular to a lamp. Background Art
[0003] With the improvement of living standards, people's demand for lighting in different scenarios is also increasing. Among them, lamps that can simulate outdoor natural ambient light have gradually gained favor in the market and are widely used in indoor lighting in 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 a blue sky and white clouds painted on it. The pattern plate is illuminated by the light source to form an outdoor blue sky light environment. However, this solution cannot truly show the matching effect of blue sky and daylight, and has poor layering and lack of three-dimensional sense, and the simulation fidelity is not good.
[0004] In response to this, a blue sky lamp design has appeared on the market that uses a light source combined with a scattering panel to create sunlight similar to that in nature. However, the light source is relatively single and cannot reflect the changes in light, and the effect is still unsatisfactory.
[0005] In view of this, it is indeed necessary to provide a lamp that can truly simulate the effect of natural light. Summary of the Invention

[0049] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.
[0050] It should be noted here that in order to avoid obscuring the present application due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the accompanying drawings, while other details that are not closely related to the present application are omitted.
[0051] 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 includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
[0052] Please refer to Figures 1-3, which are a lamp 100 of a preferred embodiment of the present application, including 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, and 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 wall.
[0053] 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 toward and away from the bottom wall 610, a light outlet is formed between the bottom wall 610 and the frame 620, the 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 toward 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.
[0054] In an optional embodiment, the first light source system 200 is a ceiling lamp comprising a chassis, a mask, and a first light-emitting module 210. The first light-emitting module 210 is a full-spectrum LED chip capable of simulating the spectrum of sunlight. In other embodiments, the first light-emitting module 210 can also be a conventional white light source. By incorporating nanoparticles into the diffusion structure 220 of the first light source system 200 to induce Rayleigh scattering, the first light-emitting surface 201 appears blue, similar to the sky. This application is not limited to this.
[0055] 2-5 , in a preferred embodiment of the present application, 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 mounted on a side of the first substrate 211 facing away from the bottom wall 610 and are electrically connected to the first substrate 211.
[0056] The light emitting module 212 includes at least two light emitting units, each of 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 in distribution.
[0057] As shown in FIG5 , in a preferred embodiment, each light-emitting module 212 of the first light-emitting module 210 includes a first light-emitting unit 2121 and a second light-emitting unit 2122. The first light-emitting units 2121 and the second light-emitting units 2122 are arranged in an alternating pattern, and adjacent first light-emitting units 2121 and second light-emitting units 2122 are arranged in an inverted pattern. The first light-emitting unit 2121 includes any two of four different colors of light-emitting elements, and the second light-emitting unit 2122 includes the remaining two of the four different colors of light-emitting elements. From left to right within a single light-emitting module, 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 are arranged in an alternating pattern. Adjacent first light-emitting units 2121 and second light-emitting units 2122 are arranged in an inverted pattern. 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.
[0058] 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 also be greater, and this application does not impose any limitation on this.
[0059] A light source lens (not shown) is also provided on the light emitting unit of the light emitting module. In the present embodiment, a light source lens is installed on each light emitting unit, that is, the light source lens and the light emitting unit are provided in a one-to-one correspondence. This arrangement allows the light emitted by the light emitting unit to be concentrated in the center of the light source lens and then emitted outward, thus avoiding interference between the light rays. In other embodiments, the light source lens may 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 may be a light source lens that covers the entire light emitting unit, thus reducing the number of light source lenses and making production and assembly more convenient and quick.
[0060] In this embodiment, the light-emitting units are arranged in a circular pattern on the first substrate 211. Specifically, they are arranged in multiple 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 based on the voltage of the light-emitting unit and the voltage of the driving power supply. In this embodiment, the voltage of the lamp beads 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.
[0061] In this embodiment, there are 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. Assume that the R1th circle is 1 string, marked as 1_1, and the R2th circle is 2 strings, marked as 2_1 and 2_2, and so on. The Rith circle is marked from i_1 to i_i, then there are i*(i+1)*(i+2) / 6 strings in total, 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 precisely 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.
[0062] 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 application does not limit this.
[0063] The first light source system 200 also includes an inner frame 250 and a diffuser structure 220. The inner frame 250 is nested within the frame 720. The diffuser structure 220 is fixedly connected to the end of the inner frame 250 facing away from the first light-emitting module 210. Light emitted by the light-emitting units in the first light-emitting module 210 passes through the diffuser structure 220, which diffuses the light, transforming linear or point light sources into a uniform surface light source. In this embodiment, the diffuser structure 220 is a diffuser plate with a transmittance of 40% to 65% and a thickness of approximately 3 mm.
[0064] The diffuser effectively eliminates the graininess of light emitted from the first light-emitting module 210 and diffuses the light. This diffuser scatters the light on its surface, spreading it softly and evenly. After the light is diffused by the diffuser, the illuminated area is larger, the light is more uniform, and the color is more stable.
[0065] 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-uniformity role. This application does not impose any restrictions on this.
[0066] 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. 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 with a sense of depth and transparency.
[0067] The reflectivity of the mirror surface of transparent plate 240 is greater than its transmittance, thereby limiting the incidence of external light on transparent plate 240 from the light-emitting surface. Alternatively, transparent plate 240 may be made of an inorganic material, such as quartz glass. Transparent plate 240 may also be made of an organic material, such as a transparent polymer material such as organic glass, which is not limited in this application.
[0068] In some embodiments, a thin unidirectional film, such as tin, silver, or aluminum, is deposited on the light-emitting surface of the transparent plate 240 using a crystal plating process to form the unidirectional film. The crystal plating process can achieve a relatively high smoothness. In other embodiments, the transparent plate 240 can be selected based on practical needs and is not limited here. The thickness of the unidirectional film can be adjusted based on practical needs. As the thickness of the unidirectional film increases, its reflectivity and transmittance change, achieving a one-way perspective effect by having a higher reflectivity than transmittance.
[0069] 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.
[0070] The second light source system 300 is detachably connected to the lamp 100. 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. 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. 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 differs from conventional ambient lighting in that it emits light only toward the inside of the lamp 100. In this embodiment, the frame 620 is made of an opaque material, creating the illusion of sunlight entering and illuminating the window sill, visually creating the effect of a light-transmitting window.
[0071] In some embodiments, the second light source system 300 does not include a separate light emitting module, and the second light emitting surface 301 is formed by directly reflecting the light emitted from the first light emitting surface 201 .
[0072] The second light source system 300 also 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. As shown in FIG18 , 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, thereby making the display effect more realistic, the second light-emitting surface 301 and the non-light-emitting surface 302 are circumferentially connected and together surround the outer circumference of the first light-emitting surface 201 to form an annular surface. 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 light / shadow transition zone 304 serves to form a light-dark boundary area between the second light-emitting surface 301 and the non-light-emitting surface 302. The light / shadow transition zone 304 can be a continuously changing area from light to dark, or a distinct dividing line.
[0073] 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 .
[0074] 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 a non-illuminated 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 on the non-light-emitting area.
[0075] 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 side of the first light-emitting surface 201 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.
[0076] The second light source system 300 can be configured as a whole to rotate relative to the first light source system 200 . The micro motor provided in the lamp 100 can be used to drive the second light source system 300 to rotate, so as to better simulate the effect of the sun rising in the east and setting in the west.
[0077] The second light source system 300 is described below through three specific embodiments, but the present invention should not be limited thereto.
[0078] Example 1
[0079] As shown in Figures 2-3 and 6, in this embodiment, the light source module 310 emits light in the same direction as the first light-emitting module 210. The second light source system 300 includes the 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 disposed 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 facing away from the frame 620. After refraction by the light distribution member 322, the light emitted from the light distribution member 322 is then emitted through the light output member 321 toward the side facing away from the frame 620. The light distribution member 322 can control the light output angle, so that the light is emitted at a small angle, with a long projection distance and greater transparency.
[0080] In some embodiments, the end of the light emitting member 321 away from the first light source system 200 is tilted 5° to 30° toward the frame 620 , so that the light emitted from the second light emitting surface 301 has a wider irradiation range.
[0081] 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 materials, which is not limited in this application.
[0082] As shown in Figure 10, in some embodiments, the light distribution component 322 is a lens, or as shown in Figure 12, in some embodiments, the light distribution component 322 is a reflective cup, the lens or reflective cup is located in the light emission direction of the light source module 310, the lens or reflective cup covers the light emitting component 312, and the light emitted by the light emitting component 312 is refracted by the lens or 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 toward this part, and the light reflected by the reflective component 232 is emitted toward the light emitting component 321.
[0083] As shown in Figure 11, in some embodiments, the light distribution component 322 is a polarized lens, or as shown in Figure 13, in some embodiments, the light distribution component 322 is an eccentric reflective cup, the polarized lens or the eccentric reflective cup covers the light-emitting component 312, and the light emitted by the light-emitting component 312 is refracted by the polarized lens or the eccentric reflective cup, and 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.
[0084] As shown in Figure 12, in some embodiments, when the light distribution component 322 is a reflective cup, a prism sheet 326 is covered on the 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 this 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.
[0085] 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 application.
[0086] As shown in Figure 6, the light source module 310 includes a light source substrate 311 and a light-emitting component 312 installed in 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 in the light guide component 320 corresponding to the light-emitting component 312 on the light source substrate 311 is in a bright state (i.e., the second light-emitting surface 301 of the second light source system 300), and the area on 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 state (i.e., the non-light-emitting surface 302 of the second light source system 300), so as to simulate the effect of sunlight shining through the window into the room and illuminating the edge of one side of the window.
[0087] In other embodiments, light-emitting elements 312 may be installed in all areas of the light source substrate 311. By controlling the operating state of the light-emitting elements 312 in different areas and illuminating different locations to achieve a change in light source, the light-emitting element can be switched between bright and dark areas, simulating the effect of sunlight shining on the edge of the skylight at different angles at different times of the day, thereby achieving sunrise and sunset. In this embodiment, the frame 620 is made of a semi-transparent or translucent material. By controlling the light-emitting elements 312 in different areas to emit different colors, a rainbow effect can be created through the frame 620, enhancing the visual experience of the lamp 100.
[0088] 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 . At the same time, the light emitted after passing through the light emitting member 321 will be more uniform.
[0089] 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.
[0090] 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 provided here can prevent light from leaking out of this area on the light emitting element 321, thereby ensuring 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.
[0091] 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 achieve changes in the bright and dark areas on the light output member 321.
[0092] The height of the light shielding member 324 can be adjusted according to actual conditions by means of an elastic member provided in conjunction with a micro motor.
[0093] Example 2
[0094] As shown in Figures 7-8, in this embodiment, the light emission direction of the light source module 310' intersects with the light emission direction of the first light-emitting module 210, and the second light source system 300 includes a light-emitting member 321, which is arranged between the frame 620 and the light-emitting surface 201, and extends beyond 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 injected into the light-emitting member 321 from the side of the light-emitting member 321.
[0095] 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, it passes through the light-emitting element 321 to achieve uniform emission of the light.
[0096] 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.
[0097] Preferably, the light emitting element 321 is made of transparent optical materials such as PMMA and PC.
[0098] 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 status 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.
[0099] In other embodiments, when the entire area of the light source substrate 311' is equipped with light-emitting elements 312, a light-shielding element 324 may be attached to a portion of the light-emitting element 321 to prevent light from escaping from that portion of the light-emitting element 321. This darkens that portion of the light-emitting element 321, simulating the effect of sunlight shining on the edge of a window or skylight. The light shield can be rotated, and by rotating the light-shielding element 324, the illuminated area on the light-emitting element 321 changes, simulating the effect of sunrise and sunset.
[0100] The overall structure of the second light source system 300 in this embodiment is simpler, and the light source module 310 ′ surrounds the outside of the light emitting member 321 , making assembly more convenient and quick.
[0101] Example 3
[0102] 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 toward 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 fine structure 3221 is provided in the second light emitting surface 301, and the fine structure 3221 allows light to be emitted at a large angle from the area of the second light emitting surface 301 where the fine structure 3221 is provided.
[0103] As shown in Figure 9, 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 away from the light source module 310. 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 provided on the light distribution component 322 at a large angle. The light emitted from the light distribution component 322 enters the light output component 321 with an inverted fine structure. The inverted fine structure 3221 is used to enable part of the light to be emitted at a small angle to the transparent plate 240 and then reflected to form a transparent virtual image 303.
[0104] Among them, the angles of the backlight surface and the light-facing surface of the microstructure 3221 on the light-distributing 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-distributing component 322, and the depth of the V-groove also changes. For a light-facing surface of less than 6 degrees, after the light enters from the light-entering side, the angle of the light exiting from the light-emitting surface is 165 to 175 degrees. The microstructure 3221 on the light-emitting side compresses the light to within 30 degrees toward the center. The light that exits at 165 to 175 degrees can be emitted at a small angle of less than 10 degrees through the inverted V prism on the light-emitting component 321. The uniformity of the light-emitting surface of the light-distributing 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.
[0105] Preferably, the angles of the backlight surface and the frontlight 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.
[0106] A reflector 323 is provided on one side of the light distribution element 322 away from the light emitting element 321 to reflect the light directed 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 .
[0107] As shown in FIG14 , the lamp 100 is further provided with a side projection device 330 , which is disposed between the frame 620 and the first light source system 200 . The side projection device 330 is configured to project a sun-like light spot. The sun-like light spot projected by the side projection device 330 enters the mirror surface of the transparent plate 240 , is reflected by the mirror surface, and then is emitted outward, forming a virtual sun spot on the first light-emitting surface 201 . The human eye can see the scene illuminated by the sun through the transparent plate 240 , making the display effect of the lamp 100 more realistic. The human eye can see the reflected virtual image on the first light-emitting surface 201 , making the display effect of the lamp 100 more realistic.
[0108] The lamp 100 also includes one or more reflecting 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 reflecting device 340 and then enters the mirror surface of the transparent plate 240. In this embodiment, the reflecting 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.
[0109] The side projection device 330 includes projection lamp beads and convex lenses, wherein the projection lamp beads are multi-color lamp beads 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 beads and obtain a uniform light spot.
[0110] The lamp 100 also includes a projection system 400, which is arranged 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 the wall or the ground, including circular spots, elliptical spots or quadrilateral light panels, similar to the projection produced by sunlight passing through a window.
[0111] The projection system 400 includes a plurality of projection devices 410. In this embodiment, two projection devices 410 are provided. Each of the two projection devices 410 is movably connected to the frame 620 of the lamp 100 via a connector. The projection devices 410 can rotate relative to the frame 620. As shown in Figures 15-16, the projection device 410 includes a light-emitting assembly 420, a lens barrel assembly 450, and a lens assembly 430. The light-emitting assembly 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 surface 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 first lens barrel 451 is provided on the side sleeve, and the second lens barrel 452 is screwed to the end of the first lens barrel 451 away from the first lens 431, and the second lens 432 is embedded in the side of the second lens barrel 452 close to the first lens barrel 451, and the end of the second lens barrel 452 away from the first lens barrel 451 is screwed to the third lens barrel 453, and the end of the third lens barrel 453 away from the second lens barrel 452 is embedded in the third lens barrel 433. The second lens 432 and the third lens 433 are configured to perform imaging, and the focal length is adjusted by using the first lens barrel 451, the second lens barrel 452 and the third lens barrel 453.
[0112] The first lens 431 and the second lens 432 are plastic lenses, and the third lens 433 is a glass lens. Plastic lenses are lighter, which is beneficial to the lightweight of the overall structure, while glass lenses can ensure higher light transmittance.
[0113] 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 this application does not limit this.
[0114] As shown in FIG17 , 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 real sunlight through the window on the wall.
[0115] 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.
[0116] The mounting system 500 includes a mounting bracket that is fixedly connected to the bottom wall 610. The lamp 100 is fixedly connected to the mounting surface via the mounting bracket. In this embodiment, the mounting system 500 is a hanging rack structure. In other embodiments, it can also be a quick-connect structure, which is not limited in this application.
[0117] In summary, the first light source system 200 in the lamp 100 of the present application can simulate effects similar to a blue sky, sunset, morning light, and blue sky with white clouds, while the second light source system 300 simulates the effect of sunlight shining on the edge of a window, making the lighting effects of the lamp 100 more realistic. The second light source system 300 can also form a virtual image 303 on the transparent plate 240 provided therein, producing a window shadow effect similar to sunlight shining on the edge of a window or skylight, thereby creating a sense of space, depth, and layering. The projection system 400 can provide a light spot similar to sunlight projected through a window or skylight onto the ground or wall. The shape of the light spot varies according to the overall shape of the lamp 100, enabling multi-scene applications.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
