[0037] 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.

[0038] 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.

[0039] 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.

[0040] See also Figure 1-Figure 8 As shown, a lamp 200 of a preferred embodiment of the utility model includes a side-emitting lighting device 100 and a surface-emitting lighting device 110. The surface-emitting lighting device 110 is configured to simulate sunlight at different time periods in nature, and the side-emitting lighting devices 100 are arranged around the surface-emitting lighting device 110. The side-emitting lighting device 100 is configured to simulate the effect of sunlight shining on the edge of the skylight. In addition, the side-emitting lighting device 100 can also form a virtual image in the surface-emitting lighting device 110.

[0041] Specifically, the surface-emitting lighting device 110 includes a main light source component 1101, which is configured to emit light outward and has a main light source light-emitting surface 1102. Preferably, the main light source component 1101 is a full-spectrum LED chip that can simulate the spectrum of daylight. In other embodiments, the main light source component 1101 can also be a conventional white light source, and nanoparticles are added to the diffusion structure of the surface-emitting lighting device 110 to form Rayleigh scattering, so that the main light source light-emitting surface 1102 appears blue like the sky. The utility model is not limited to this. Preferably, the surface-emitting lighting device 110 also includes a light source component arranged above the side-emitting lighting device 100, and the light source component emits light toward the installation surface, and the installation surface is generally a ceiling, to achieve a light and shadow effect of washing the ceiling.

[0042] The surface-emitting lighting device 110 also includes a light emitting plate 1103 arranged on the main light source light emitting surface 1102. The side of the light emitting plate 1103 facing away from the main light source assembly 1101 is a mirror 1104. At least part of the light emitted by the side-emitting lighting device 100 is projected onto the mirror 1104 after passing through the first light outlet 114, and is reflected by the mirror 1104 to form a virtual image on the main light source light emitting surface 1102, 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.

[0043] Specifically, the side-emitting lighting device 100 includes a housing 11 and a light source module 12 installed in the housing 11. The housing 11 includes a top wall 111 and a bottom wall 112 that are arranged opposite to each other, and a frame 113 connecting the top wall 111 and the bottom wall 112. A light source installation space 115 is formed between the top wall 111, the bottom wall 112 and the frame 113, and a first light outlet 114 is provided on the side of the light source installation space 115 away from the frame 113. The first light outlet 114 of the side-emitting lighting device 100 is connected to the main light source light emitting surface 1102 and extends in a direction away from the main light source light emitting surface 1102, ensuring that the light emitted by the side-emitting lighting device 100 can be smoothly projected onto the mirror surface 1104 of the light emitting plate 1103 of the surface-emitting lighting device 110. This direct projection path effectively reduces the scattering and loss of light. At the same time, the extension of the first light outlet 114 forms a certain space distance between the light source of the side-emitting lighting device 100 and the light-emitting surface of the surface-emitting lighting device 110, making the ambient light of the side-emitting lighting device 100 more prominent visually and having a sense of hierarchy. This sense of distance makes the light propagation between the two softer, avoiding direct or overly strong light effects, thereby creating a more comfortable and natural lighting environment.

[0044] The light source module 12 includes at least two light source components 121 and a light distribution component 122, and at least two light source components 121 are arranged on different sides of the light source installation space 115 to achieve multi-angle lighting and improve the lighting uniformity of the lighting device. The light distribution component 122 is arranged in the light output path of the light source module 12 and is arranged one-to-one with the light source component 121. The light distribution component 122 is any one or a combination of a light guide plate, a lens, a reflector, and a reflective cup, which is selected according to the application scenario. The light emitted by the light source module 12 is emitted from the first light outlet 114 after being acted upon by the light distribution component 122. In this arrangement, the light emitted by the light source module 12 is emitted from the first light outlet 114 after being regulated by the light distribution component 122, further enhancing the uniformity of the lighting effect. Due to the use of at least two light source components 121 and the corresponding light distribution components 122, the light brightness is effectively improved.

[0045] In this embodiment, the side-emitting lighting device 100 can effectively improve the lighting brightness by arranging more than two light source components 121 on different sides of the light source installation space 115; the light emitted by the light source module 12 is regulated by the light distribution component 122 and then emitted from the first light outlet 114, which effectively reduces the waste of light, improves the utilization rate of light energy, and achieves efficient and uniform lighting effects. In addition, the number and layout of the light source components 121, as well as the shape and material of the light distribution component 122, can be adjusted according to specific needs, so as to flexibly control the lighting effect and meet the lighting requirements of different environments.

[0046] Furthermore, the side-emitting lighting device 100 further includes a light emitting member 13, which is a diffuser in this embodiment, and may be other equivalent components in other embodiments, which is not limited here. The light emitting member 13 is disposed at the first light outlet 114, abuts against the top wall 111 and the bottom wall 112, and is located on the inner side of the frame 113. The light emitted by the light source module 12 is emitted through the light emitting member 13 after being acted upon by the light distribution member 122, and the light emitting member 13 evens the light before emitting it, thereby improving the uniformity of the emitted light.

[0047] Furthermore, each light source assembly 121 includes a light source substrate 1211 and a plurality of light emitting elements 1212 disposed on the light source substrate 1211. The plurality of light emitting elements 1212 can be independently controlled, and by controlling the lighting state of the light emitting elements 1212, an illuminated light emitting area and a non-illuminated non-light emitting area are formed at the first light emitting port 114, and a light / shadow transition zone is provided between the light emitting area and the non-light emitting area; to simulate the sunlight entering from one side, illuminating the window edge on one side of the window, and forming a dark surface on the window edge on the other side of the window, so that the display effect is more realistic, the light emitting area and the non-light emitting area are circumferentially connected, and together form an annular surface at the outer periphery of the first light emitting port 114, and the light / shadow transition zone is located at the junction of the light emitting area and the non-light emitting area, and the light / shadow transition zone serves to form a light-dark boundary area between the light emitting area and the non-light emitting area, which can be an area that continuously changes from light to dark, or a clear dividing line.

[0048] In a preferred embodiment, each light source assembly 121 includes a light source substrate 1211 partially surrounding the first light outlet 114 and a plurality of light emitting elements 1212 disposed on the light source substrate 1211. The light emitting elements 1212 are configured to form an illuminated light outlet area on the first light outlet 114, and to form a non-illuminated non-light outlet area on the first light outlet 114 not surrounded by the light source assembly 121. There is a light / shadow transition zone between the light outlet area and the non-light outlet area. This arrangement is used to simulate the situation that when sunlight enters from one side, one side of the window edge is illuminated, and a dark side is formed on the other side of the window edge, so that the display effect is more realistic. The light outlet area is connected to the non-light outlet area in an annular direction and forms an annular surface on the outer periphery of the first light outlet 114. The light / shadow transition zone is located at the junction of the light outlet area and the non-light outlet area. The light / shadow transition zone is used to form a light-dark boundary area between the light outlet area and the non-light outlet area, which can be a continuously changing area from light to dark, or a clear dividing line.

[0049] In other embodiments, the side-emitting lighting device 100 includes a shading member, which is arranged together with the light source module 12 around the first light outlet 114, and the light source module 12 is configured to form an illuminated light outlet area on the first light outlet 114, and the shading member is configured to form a non-light outlet area on the first light outlet 114 that is not illuminated, and there is a light / shadow transition zone between the light outlet area and the non-light outlet area. Such arrangement is used to simulate the sunlight entering from one side, illuminating one side of the window edge, and forming a dark side on the other side of the window edge, so that the display effect is more realistic, the light outlet area and the non-light outlet area are connected in an annular direction, and together form an annular surface on the outer periphery of the first light outlet 114, and the light / shadow transition zone is located at the junction of the light outlet area and the non-light outlet area, and the light / shadow transition zone is used to form a light-dark boundary area between the light outlet area and the non-light outlet area, which can be a continuous changing area from light to dark, or a clear dividing line.

[0050] The light source assembly 121 includes a light source substrate 1211 and at least two light emitting elements 1212 of different colors disposed on the light source substrate 1211. The at least two light emitting elements 1212 of different colors are arranged in a circular pattern on the light source substrate 1211 in sequence, so that the emitted light color is more uniform. The light source assembly 121 controls the light emitting elements 1212 to emit different colors through programming or intelligent control, and can conveniently adjust the light intensity and duration of the light emitting elements of different colors to simulate the color of sunlight at different times, thereby creating various dynamic light and shadow changes and achieving a dynamic effect of light.

[0051] Example 1

[0052] In this embodiment, the light source module 12 includes a light source assembly 121 and a light distribution member 122. Further, the light source assembly 121 includes a first light source assembly and a second light source assembly, one of which is arranged on the top wall 111 and the other is arranged on the bottom wall 112. The light distribution member 122 includes a first light distribution member and a second light distribution member, which are respectively covered on the first light source assembly and the second light source assembly.

[0053] Specifically, the first light source assembly is mounted on the top wall 111, and the first light distribution component 1 is a reflector, specifically a reflective cup. After the light emitted by the first light source assembly is refracted by the reflective cup, part of the light is emitted toward the light output component 13, and part of the light is emitted toward the frame 113. A reflector 14 is provided on the frame 113 to reflect the light emitted toward this part, and the light reflected by the reflector 14 is emitted toward the light output component 13. Specifically, the reflector 14 is provided on the side of the frame 113 facing the first light outlet 114. After the light emitted by the light source assembly 121 is acted upon by the light distribution component 122, part of the light is emitted directly through the first light outlet 114, and part of the light is emitted toward the frame 113, and then is reflected by the reflector 14 and emitted from the first light outlet 114. In other embodiments, the reflector 14 may be a reflective film, that is, a highly reflective material is sprayed on the frame 113. This is not limited here.

[0054] The reflective cup includes a small opening that is covered on the first light source assembly and a large opening that is away from the first light source assembly; the small opening design can effectively gather the light emitted by the first light source assembly. Due to the focusing effect of the small opening on the light, the light is concentrated before being emitted, thereby improving the utilization rate of the light and reducing the waste of light energy. This design enables the lamp to emit brighter and more concentrated light at the same power, thereby improving the lighting effect. The large opening of the reflective cup is responsible for reflecting the light and increasing the light output angle. The design of the large opening enables the light to be emitted at a wider angle after reflection, thereby expanding the lighting range and reducing the shadow area. This design makes the lighting effect of the lamp 200 more uniform and avoids the lighting dead angle caused by uneven light distribution. The combination of the focusing and reflection effects of the reflective cup can optimize the distribution and projection effect of the light. By adjusting the shape, material and surface treatment of the reflective cup, the direction of the light can be accurately controlled so that the light can be emitted according to a predetermined path and angle to meet different lighting needs. In this embodiment, a prism sheet is covered on one end of the reflective cup away from the first light source assembly. The prism sheet is configured to refract part of the light emitted by the light-emitting component 1212 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-emitting component 13 or toward the reflective component 14 on the frame 113, thereby improving the utilization rate of the light emitted by the light source module 12.

[0055] The second light source assembly is mounted on the bottom wall 112, and the second light distribution member 2 is a lens. The lens is connected to the inner side of the light source substrate 1211 and covers the light emitting member 1212. The light emitted by the light emitting member 1212 is incident on the light incident surface of the lens, refracted on the light incident surface, enters the lens under the condition of satisfying Snell's law, and then refracted on the light exiting surface. After being emitted from the lens, it passes through the light exiting member 13 to realize uniform emission of the light.

[0056] Example 2

[0057] The above-mentioned embodiment 1 provides a side-emitting lighting device 100 applied to a lamp 200. The principle of this embodiment is the same as that of the embodiment 1, except that the installation position of the light source assembly 121 is different. Therefore, only the differences in structure are described here, and the same parts are not repeated. One of the first light source assembly and the second light source assembly is arranged on the top wall 111 or the bottom wall 112, and the other is arranged on the frame 113.

[0058] The light emitted by the light source assembly arranged on the bottom wall 112 and the frame 113 is regulated by the light distribution member 122 and then emitted from the first light outlet 114, forming a surround lighting effect, which is particularly suitable for scenes that need to create a spatial atmosphere. The light source assembly 121 on the bottom wall 112 can project light downward, while the light source assembly 121 on the frame 113 can project light to the side and upward, illuminating the edge of the lamp, and echoing with the light source assembly 121 on the bottom wall 112, enhancing the sense of space and layering, thereby forming a three-dimensional lighting effect.

[0059] The light source assembly 121 disposed on the top wall 111 mainly emits light upward, which can illuminate the upper part or ceiling of the lamp 200, and complements the light source assembly 121 on the frame 113, so that the lighting effect of the entire lamp 200 is more complete. The light source assemblies 121 on the top wall 111 and the frame 113 can cooperate with each other to make the light more evenly distributed around the lamp 200, reduce the shadow area, and significantly improve the overall brightness of the lamp, which is particularly suitable for lighting scenes that require high brightness.

[0060] Example 3

[0061] The above-mentioned embodiment 1 provides a side-emitting lighting device 100 applied to a lamp 200. The principle of this embodiment is the same as that of the embodiment 1, except that the structure of the housing 11 is different. Therefore, only the differences in structure are described here, and the same parts are not repeated.

[0062] In this embodiment, the housing 11 is at least partially light-transmissive, and the housing 11 also includes a second light outlet arranged opposite to or adjacent to the first light outlet 114. The light emitted by the light source module 12 passes through the light distribution component 122 and is emitted through the first light outlet 114 and the second light outlet respectively, so as to realize the light emission inside and outside. The light passing through the housing 11 can not only illuminate its external space, but also provide sufficient light for the internal space, creating a unique light and shadow effect. This design is particularly suitable for occasions where it is necessary to pay attention to the internal and external environmental lighting at the same time, such as display cabinets, windows, etc., which can fully display the objects while providing a comfortable visual experience for the observer.

[0063] In summary, the side-emitting lighting device 100 of the utility model can effectively improve the lighting brightness by respectively setting more than two light source components 121 on different sides of the light source installation space 115. A light distribution component 122 is set in the light output path of the light source module 12, and the light distribution component 122 is set one-to-one with the light source component 121. The light emitted by the light source module 12 is regulated by the light distribution component 122 and then emitted from the first light outlet 114, which effectively reduces the waste of light, improves the utilization rate of light energy, and achieves efficient and uniform lighting effects. In addition, the number and layout of the light source components 121, as well as the shape and material of the light distribution component 122, can be adjusted according to specific needs, so as to flexibly control the lighting effect and meet the lighting requirements of different environments.

[0064] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
