[0040] 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.

[0041] 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.

[0042] 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.

[0043] See also Figures 1 to 9 As shown, the utility model provides a lamp 300 , including a surface-emitting lighting device 200 and a side-emitting lighting device 100 , wherein the surface-emitting lighting device 200 is arranged inside the side-emitting lighting device 100 and is surrounded by the side-emitting lighting device 100 .

[0044] The side-emitting lighting device 100 includes a housing 110, the housing 110 includes a top wall 120 and a frame 130, the frame 130 is connected to the top wall 120 and extends in a direction away from the top wall 120, the frame 130 is configured to at least partially transmit light, the frame 130 includes a first light emitting surface 131 and a second light emitting surface 132, the first light emitting surface 131 is arranged on the inner side of the frame 130 facing the top wall 120, the second light emitting surface 132 is adjacent to or opposite to the first light emitting surface 131, and a light source installation space 133 is formed between the first light emitting surface 131 and the second light emitting surface 132;

[0045] The side-emitting lighting device 100 also includes a light source assembly 140 arranged in a light source installation space 133. The light emitted by the light source assembly 140 is emitted after passing through a first light emitting surface 131 and a second light emitting surface 132, and a light emitting area 301 is formed on the first light emitting surface 131. The first light emitting surface 131 is also provided with a non-light emitting area 302 circumferentially connected to the light emitting area 301, and a light / shadow transition area 304 is provided between the light emitting area 301 and the non-light emitting area 302.

[0046] Among them, the frame 130 is configured to be at least partially transparent to light, and has a first light emitting surface 131 and a second light emitting surface 132, so that the light emitted by the light source assembly 140 can be emitted from multiple directions, increasing the light emitting angle and range of the lighting device, so that a better lighting effect can be formed on the outside of the frame 130, making the lamp 300 more atmospheric and improving the user's experience. By forming a light / shadow transition zone 304 on the first light emitting surface 131, it simulates the effect of illuminating one side of the window and forming a dark side on the other side of the window when sunlight enters from one side. The light / shadow transition zone 304 makes the change of light more natural and soft, avoiding too abrupt light switching. The light source assembly 140 is arranged in the light source installation space 133, which means that the light source assembly 140 itself is hidden inside the device and will not be directly exposed to the outside, which enhances the overall aesthetics of the side-emitting lighting device 100.

[0047] See also Figures 2 to 3 As shown, in some embodiments, the frame 130 includes an inner side wall 134 and an outer side wall 135 that are arranged opposite to each other, the outer side wall 135 is arranged around the top wall 120, the inner side wall 134 is arranged inside the outer side wall 135 and is surrounded by the outer side wall 135, wherein the inner side wall 134 is the first light emitting surface 131 of the frame 130. By setting the inner side wall 134 as the first light emitting surface 131 of the frame 130, the light emitted by the light source assembly 140 can be directly and effectively emitted from the inner side wall 134, reducing the reflection and scattering of the light inside the light source installation space 133, improving the utilization rate of the light, and also reducing the number of parts in the side-emitting lighting device 100, making assembly more convenient. At the same time, the outer side wall 135 is arranged around the top wall 120, which not only enhances the stability of the structure, but also can prevent the light from the outside from directly irradiating the internal light source assembly 140 to a certain extent, further improving the control effect of the light.

[0048] In other embodiments, the frame 130 includes an outer wall 135 disposed around the top wall 120, and a bottom wall 136 connected to the outer wall 135 and away from the top wall 120, the first light emitting surface 131 is a light outlet disposed on the inner side of the outer wall 135, and the side-emitting lighting device 100 further includes a light outlet, the light outlet abuts against the bottom wall 136 and is disposed at the light outlet, and the light emitted by the light source assembly 140 is emitted after passing through the light outlet and the light outlet. By arranging the light outlet on the inner side of the outer wall 135, and the light outlet abuts against the bottom wall 136 and is located at the light outlet, the light emitted by the light source assembly 140 can be guided by the light outlet and the light outlet, so as to achieve a more uniform and accurate light distribution. Optionally, the light outlet can be a diffuser. Of course, it is known to those skilled in the art that different lighting effects and appearance styles can be achieved by adjusting the size, shape and position of the light outlet, and selecting light outlets of different materials and designs. This provides more flexibility and creative space for the design of the lighting device.

[0049] For further information, see Figure 3 As shown, the frame 130 further includes a third light emitting surface 137, the first light emitting surface 131 is arranged on the inner side of the frame 130 facing the top wall 120, and the second light emitting surface 132 and the third light emitting surface 137 are respectively arranged on the outer side wall 135 and the bottom wall 136 of the frame 130. By setting a plurality of light emitting surfaces, the side-emitting lighting device 100 can achieve a full range of lighting effects. This can not only meet the lighting needs of different areas in the space, but also create a rich variety of light and shadow effects, enhance the layering and three-dimensional sense of the overall space, and effectively improve the visual effect of the space.

[0050] In some embodiments, participation Figures 2 to 3 as well as Figures 5 to 7 As shown, the light source assembly 140 is arranged on the top wall 120, so that the light can be projected downward more concentratedly, thereby improving the brightness of the illuminated area. Through reasonable optical design, the light source assembly 140 on the top wall 120 can achieve a more uniform lighting effect, reduce the generation of shadows and light spots, and provide a comfortable visual environment.

[0051] In some other embodiments, see Figure 8 As shown, the light source assembly 140 may also be disposed on the frame 130 to form a better light and shadow level and depth in the space, thereby enhancing the sense of space.

[0052] Furthermore, the light source assembly 140 includes a light source substrate 141 arranged around the first light emitting surface 131 and a plurality of light emitting components 142 arranged on the light source substrate 141. The plurality of light emitting components 142 can be independently controlled to form an illuminated light emitting area 301 and an unilluminated non-light emitting area 302 on the first light emitting surface 131 by controlling the lighting state of the light emitting components 142.

[0053] Furthermore, the light source assembly 140 includes a light source substrate 141 that partially surrounds the first light emitting surface 131 and a light-emitting component 142 disposed on the light source substrate 141, and the light-emitting component 142 is configured to form an illuminated light emitting area 301 on the first light emitting surface 131, and to form a non-illuminated non-light emitting area 302 on the first light emitting surface 131 that is not surrounded by the light source assembly 140.

[0054] Furthermore, the side-emitting lighting device 100 includes a shading member, which is disposed together with the light source assembly 140 around the first light emitting surface 131. The light source assembly 140 is configured to form an illuminated light emitting area 301 on the first light emitting surface 131, and the shading member is configured to form a non-light emitting area 302 that is not illuminated on the first light emitting surface 131. By forming the light emitting area 301 and the non-light emitting area 302 on the light emitting surface, the effect of illuminating a portion of the window edge when real sunlight is obliquely incident on the window edge is simulated, so that the display effect of the side-emitting lighting device 100 is more realistic.

[0055] For further information, see Figures 5 to 7 As shown, the light source assembly 140 includes at least a first light source assembly 143 and a second light source assembly 144. In some embodiments, the first light source assembly 143 is arranged on the side of the top wall 120 facing the frame 130 or the first light source assembly 143 is arranged on the frame 130, and emits light to the first light emitting surface 131 and the second light emitting surface 132; in some other embodiments, the first light source assembly 143 can also be arranged on the side of the top wall 120 facing the frame 130 and on the frame 130 at the same time, and the utility model does not limit this. The second light source assembly 144 is arranged on the side of the top wall 120 away from the frame 130, and emits light in a direction away from the top wall 120. The light emitted by the second light source assembly 144 is directed to the ceiling 400 or the suspended ceiling to form an effect of washing the ceiling 400, so that the lighting effect of the lamp 300 is more layered.

[0056] Furthermore, the arrangement shape of the plurality of light emitting elements 142 on the light source substrate 141 is any one of a straight line, a curve, a ring, and an array. By selecting a suitable arrangement of the light emitting elements 142, the lighting effect can be optimized, and the light emitting elements 142 in the above arrangement shape can be controlled in different areas to present a richer lighting pattern and create a unique visual effect.

[0057] Furthermore, the light source assembly 140 includes at least two light emitting elements 142 of different colors, and the at least two light emitting elements 142 of different colors are sequentially and cyclically arranged on the light source substrate 141. By providing a plurality of light emitting elements 142 of different colors, a more colorful lighting effect can be presented.

[0058] Furthermore, the side-emitting lighting device 100 further includes a light distribution member 170, which is disposed in the light emitting line of the light source assembly 140. The light emitted by the light source assembly 140 is emitted toward the first light emitting surface 131 and the second light emitting surface 132 after being acted upon by the light distribution member 170. By setting the light distribution member 170, the emission angle of the light emitted by the light source assembly 140 can be controlled, so that the light is emitted at a small angle, with a long projection distance and stronger transparency.

[0059] Further, in some embodiments, the light distribution element 170 is any one or a combination of a light guide plate, a lens, a reflector, and a reflective cup. Figure 5 As shown, in this embodiment, the light distribution member 170 is a light guide plate, which has a high light conversion rate, uniform light output, and can be applied to various light sources. Figure 6 As shown, in this embodiment, the light distribution element 170 is a lens, which has enhanced light focusing ability and increases light intensity. Figure 7 As shown, in this embodiment, the light distribution component 170 is a reflector, which has a high reflectivity, usually more than 95%, and can better control the emission direction of light. It should be noted that those skilled in the art can select a suitable light distribution component according to actual needs.

[0060] Furthermore, the surface-emitting lighting device 200 has a main light source light emitting surface 210, and the first light emitting surface 131 is arranged around the main light source light emitting surface 210. At least part of the light emitted by the light source assembly 140 is projected onto the main light source light emitting surface 210 after passing through the first light emitting surface 131, so as to form a virtual image 303 on the main light source light emitting surface 210. The virtual image 303 formed on the main light source light emitting surface 210 can simulate the window shadow effect formed on the window when one side of the window is illuminated by sunlight, so that the human eye sees a sense of depth and transparency.

[0061] In summary, the light emitted by the light source assembly 140 in the side-emitting lighting device 100 of the present invention can be emitted from multiple directions, which increases the light emitting angle and range of the side-emitting lighting device 100, so that a better lighting effect can be formed on the outside of the frame 130, and the lamp 300 has a more atmospheric feeling. By forming a light / shadow transition zone 304 on the first light-emitting surface 131, the effect of illuminating one side of the window and forming a dark side on the other side of the window when sunlight enters from one side is simulated. The light / shadow transition zone 304 makes the change of light more natural and soft, avoiding too abrupt light switching. At the same time, at least part of the light emitted by the light source assembly 140 in the side-emitting lighting device 100 is projected onto the main light source light-emitting surface 210 after passing through the first light-emitting surface 131, so as to form a virtual image 303 on the main light source light-emitting surface 210, simulating the window shadow effect formed on the window when one side of the window is illuminated by sunlight, and bringing a more realistic visual experience to the user.

[0062] 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.
