[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 10 As shown, a lamp 100 of a preferred embodiment of the utility model is provided, and the lamp 100 includes a surface-emitting lighting device 200 and a side-emitting lighting device 300, wherein the surface-emitting lighting device 200 is set as a main light source, configured to emit light outwards, and can simulate natural effects such as blue sky, sunset, and morning light, and the side-emitting lighting device 300 is set as an auxiliary light source, and can restore the real scene when sunlight shines on the window.

[0044] The lamp 100 of the present invention can be applied to different types of suspended ceilings. Figure 1As shown, when installed to the integrated ceiling, the lamp 100 includes a clamping portion 260 provided on the surface-emitting lighting device 200. The clamping portion 260 is configured to clamp the lamp 100 to the installation base (wall, ceiling, etc.). At this time, the clamping portion 260 is a keel claw. The keel claw is fixed to the surface-emitting lighting device 200 by screws, and the whole is placed on the triangular keel. The keel claw will be clamped on the triangular keel, so that the surface-emitting lighting device 200 cannot move left and right to avoid the risk of falling. Then the side-emitting lighting device 300 is electrically connected to the surface-emitting lighting device 200 and clamped into the triangular keel on the side, and the lamp 100 is installed.

[0045] See also Figure 2 As shown, when the lamp 100 is installed on the T-shaped keel ceiling, the surface-emitting lighting device 200 is directly placed in the frame 310 of the side-emitting lighting device 300, and the whole is placed on the T-shaped keel, and the circuit is turned on.

[0046] In different ceiling installation scenarios, the lamp 100 can be built into the ceiling. The plane where the surface light emitting element 240 is located is higher than the plane where the lowest point of the installation base is located. From the appearance, only the effect like a window frame can be seen. The three-dimensional sense is stronger and the thickness of the lamp 100 is thinner, which is more beautiful.

[0047] See also Figure 3 As shown, the surface light emitting lighting device 200 includes a bottom wall 210, an outer frame 220, a surface light source assembly 230 and a surface light emitting member 240. The outer frame 220 is arranged around the bottom wall 210. The outer frame 220 and the bottom wall 210 are jointly arranged to form a surface light source space 250. The surface light emitting member 240 is arranged on a side of the outer frame 220 away from the bottom wall 210 and closes the surface light source space 250. The surface light source assembly 230 is arranged in the surface light source space 250. The light emitted by the surface light source assembly 230 is emitted in a direction away from the surface light emitting member 240 after passing through the surface light emitting member 240. The surface light source assembly 230 can work in a relatively closed and compact space, ensuring efficient use and concentration of light and reducing energy loss. The surface light emitting lighting device 200 also includes a light blocking member 270, which effectively prevents light loss and ensures that light is only emitted from the surface light emitting member 240.

[0048] The surface light emitting member 240 includes a surface diffuser (not shown) and a transparent member (not shown) stacked together, and the transparent member is arranged on the side of the surface diffuser away from the bottom wall 210. The light emitted by the surface light source assembly 230 is diffused by the surface diffuser, and the light is emitted more evenly. The arrangement of the transparent member makes the lamp 100 look more transparent to the naked eye when it is lit, and cooperates with the light emitted by the side-emitting lighting device 300 to reflect the depth of the sky light, which is closer to the real scene of sunlight shining in from the window.

[0049] Preferably, in this embodiment, the surface diffuser and the transparent member are integrally formed to reduce looseness or damage caused by component assembly, making the installation process simpler and faster, and maintenance more convenient, while also avoiding the air layer condition caused by the separate setting.

[0050] In another embodiment, the transparent member is a mirror, and at least part of the light emitted by the side-emitting lighting device 300 is projected onto the mirror after passing through the side light-emitting member 330 to form a virtual image, thereby producing a window shadow effect similar to sunlight shining on the edge of a window, thereby forming a sense of space, depth and layering.

[0051] A power supply assembly 400 is also disposed on the bottom wall 210 . The power supply assembly 400 is electrically connected to the surface light emitting lighting device 200 to supply power to the surface light source assembly 230 .

[0052] The side-emitting lighting device 300 is disposed around the surface-emitting lighting device 200 , and includes a frame 310 , a side light source assembly 320 , a side light emitting element 330 and a side light guiding element 340 .

[0053] The frame 310 is in contact with the surface emitting lighting device 200 and extends beyond the surface light emitting member 240 in a direction away from the surface emitting lighting device 200. The side light emitting member 330 is arranged on the inner side of the frame 310 facing the surface emitting lighting device 200, avoiding direct illumination of the human eye and reducing the possibility of glare and blindness. In addition, one end of the side light emitting member 330 is in contact with the surface light emitting member 240 and the other end is in contact with the frame 310. A light source installation space 360 ​​is formed between the side light emitting member 330 and the frame 310, and the side light source assembly 320 is arranged in the light source installation space 360. The side emitting lighting device 300 can form a certain light and shadow effect in the space by projecting light from the side, increasing the sense of hierarchy and three-dimensionality of the space, making the lighting no longer single, but more abundant and diversified.

[0054] See also Figures 4 to 6As shown, the side light guide 340 is arranged between the side light source assembly 320 and the side light output member 330, and includes a first light guide portion 3410 and a second light guide portion 3420. The first light guide portion 3410 and the second light guide portion 3420 are bent and connected, and the angle between the first light guide portion 3410 and the second light guide portion 3420 is greater than 30° and less than 150°. The first light guide portion 3410 is arranged close to the side light source assembly 320, and has a light incident surface 3411, and the light incident surface 3411 receives the light emitted by the side light source assembly 320 to ensure that the light can efficiently enter the side light guide 340. The light is sequentially conducted by the first light guide portion 3410 and the second light guide portion 3420 in the side light guide 340, and then emitted in a direction away from the frame 310 through the side light output member 330. The arrangement of the first light guide portion 3410 and the second light guide portion 3420 achieves uniform distribution and expansion of light, avoiding the problem of excessive concentration or dispersion of light. At the same time, the non-coplanar arrangement of the first light guide portion 3410 and the second light guide portion 3420 further increases the propagation path and diffusion range of the light, so that the side light output element 330 has a longer light mixing area and more uniform light mixing.

[0055] The second light guiding portion 3420 includes a light emitting surface 3421 facing the side light emitting element 330 and a reflecting surface 3422 facing the frame 310. The light emitting surface 3421 is arranged in close contact with the side light emitting element 330. There is an angle between the side light emitting element 330 and the surface light emitting element 240, and the angle is greater than 80° and less than 120°. This can ensure that the light emitted by the side-emitting lighting device 300 can be fully emitted from the side light emitting element 330.

[0056] The second light guide portion 3420 is provided with a reflective structure 3423 on the reflective surface 3422, and the reflective structure 3423 is configured to reflect the light irradiated onto the reflective surface 3422, so as to improve the light utilization rate and light uniformity. By reflecting on the reflective structure 3423 of the reflective surface 3422, the light that may have been lost or wasted can be reflected back into the side light guide 340, thereby increasing the light utilization rate. Multiple reflections and diffusions help to fully utilize and diffuse the light inside the side light guide 340, thereby improving the overall brightness of the lighting system. The reflective structure 3423 can be a mesh structure protruding from the reflective surface 3422, or a mesh structure recessed into the reflective surface 3422, or a high-reflective material sprayed on the reflective surface 3422, and the present invention is not limited to this, refer to Fig.10 As shown, the reflective structure 3423 of this embodiment is a dot structure that is recessed toward the side light emitting element 330 , which destroys the total reflection of light on the reflective surface 3422 and allows a portion of light to be reflected and refracted from the reflective structure 3423 .

[0057] The first light guide portion 3410 and the second light guide portion 3420 may also be arranged relative to each other, in which case the side light guide member 340 further includes a third light guide portion 3430 arranged between the first light guide portion 3410 and the second light guide portion 3420, wherein the first light guide portion 3410 and the second light guide portion 3420 are parallel but do not overlap, an angle is formed between the third light guide portion 3430 and the first light guide portion 3410, and an angle is formed between the third light guide portion 3430 and the second light guide portion 3420. The third light guide portion 3430 includes at least one arcuate surface 3431, a part of the light emitted by the side light source assembly 320 is emitted through the arcuate surface 3431, and another part is emitted to the second light guide portion 3420 after passing through the arcuate surface 3431. The third light guide portion 3430 is designed with at least one curved surface 3431 so that the light emitted by the side light source assembly 320 can be more evenly emitted to the second light guide portion 3420 after passing through the curved surface 3431. The curved surface 3431 increases the propagation path length of the light in the side light guide component 340, which not only improves the utilization rate of the light, but also helps to reduce the loss of light in the transmission process, thereby improving the overall efficiency of the lighting system.

[0058] The frame 310 includes a first portion 3101 and a second portion 3102 that are arranged at an angle, the first portion 3101 extends in a direction away from the surface light emitting member 240, the second portion 3102 is arranged at one end of the first portion 3101 away from the surface light emitting member 240, and abuts against the side light emitting member 330, and the side light source assembly 320 is arranged on the first portion 3101 or on the second portion 3102. The angle design of the frame 310 can reduce the loss and scattering of light at the frame 310, thereby improving the lighting efficiency and quality.

[0059] In the lamp 100 of the present invention, the shape of the side light guide 340 can be designed as needed, such as L-shaped and n-shaped. Both shapes of the side light guide 340 can provide effective light guiding and light emitting effects according to actual needs.

[0060] Specifically, in this embodiment, please refer to Fig.10As shown, the side light guide 340 is arranged in an L shape, and at this time, there is an angle between the first light guide part 3410 and the second light guide part 3420. In the L-shaped design, the side light source assembly 320 is arranged on the first part 3101 of the frame 310, that is, the side light source assembly 320 directly faces the light incident surface 3411 of the side light guide 340, and emits light toward the light incident surface 3411. The light enters the L-shaped side light guide 340 from the light incident surface 3411, and after passing through the first light guide part 3410, the light is uniformly emitted to the second light guide part 3420. The light is mixed in the first light guide part 3410, so that the light entering the second light guide part 3420 has uniform brightness. The light is then reflected to the side light output part 330 through the reflection structure 3423 on the second light guide part 3420. The second light guide part 3420 is close to the side light output part 330, which effectively avoids light loss. The L-shaped design increases the length of the light mixing area, thereby having the effect of a narrow frame. Due to the bending design of the L-shape, under the condition of the same light mixing length, the height of the L-shaped side light guide 340 is lower, which effectively utilizes the space.

[0061] In another embodiment, see Fig.11 As shown, the side light guide 340 can also be arranged in an n-shape, in which case the first light guide portion 3410 and the second light guide portion 3420 are arranged in parallel. Since the n-shape design has a longer path, the propagation distance of the light inside the side light guide 340 increases, so that the light can be better diffused in the space, improving the uniformity of the lighting area. The n-shape design is more flexible and can be adjusted according to the installation environment. The side light source assembly 320 is arranged on the second part 3102, and the position and direction can be adjusted as needed to adapt to different lighting needs.

[0062] Preferably, in the L-shape and the n-shape, the length of the first light guide portion 3410 is smaller than the length of the second light guide portion 3420, so that the light mixing length is increased within a limited space, thereby making the light output more uniform.

[0063] See also Figure 7 to Figure 9 As shown, the side-emitting lighting device 300 also includes a side shading member 350, which is arranged together with the side light guide member 340 around the side light output member 330. The light emitted by the side light source assembly 320 forms a light output area 3301 on the side light output member 330 after passing through the side light guide member 340, and the shading member forms a non-light output area 3302 on the side light output member 330, so that the lighting effect of the lamp 100 is softer and more natural, and the sense of spatial hierarchy is enhanced at the same time. The light / shadow transition area can be a light-dark boundary area formed between the light output area 3301 and the non-light output area 3302, which is a continuously changing area from light to dark, or it can be a clear dividing line, so that the side light output window shadow has a clear cutoff line, making the window shadow effect more realistic.

[0064] The side light guide 340 and the side light shielding member 350 have the same shape for better matching and installation. The side light guide 340 includes a connection side connected to the side light shielding member 350, and the connection side has a first inclined surface 3441. Accordingly, the side light shielding member 350 is provided with a second inclined surface 3510 matching the first inclined surface 3441 at a position corresponding to the first inclined surface 3441. When the side light guide 340 and the side light shielding member 350 are assembled together, the first inclined surface 3441 and the second inclined surface 3510 are spliced ​​to form a light / shadow transition line 3303 between the light emitting area 3301 and the non-light emitting area 3302, further enhancing the visual effect and aesthetics of the lamp 100.

[0065] In summary, the lamp 100 of the utility model includes a surface-emitting lighting device 200 and a side-emitting lighting device 300, wherein the surface-emitting lighting device 200 provides basic lighting and can simulate natural effects such as blue sky, sunset, and morning light, and the side-emitting lighting device 300 can restore the real scene when sunlight shines on the window, making the lighting effect of the lamp 100 more realistic, and can adjust the use of light sources according to different lighting needs to achieve diversified lighting effects. The design of the L-shaped or n-shaped side light guide 340 makes full use of space, increases the length of mixed light, makes the light output effect more uniform, and achieves a narrow frame effect.

[0066] 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.
