[0066] Embodiment 1

[0067] As Figures 1-7 shown, the embodiment 1 of the present application provides a lamp body, comprising:

[0068] The square structure lamp box 10 is provided with an opening at the bottom;

[0069] The light source module 20 is arranged in the interior of the lamp box 10;

[0070] The light emitting assembly is arranged at the opening position of the bottom of the lamp box 10, and the light emitting assembly comprises the light emitting plate 30 and the decorative frame 60 arranged in sequence, the decorative frame 60 is formed with the light emitting port 601 located below the light emitting plate 30, the top of the decorative frame 60 is matched with the bottom of the light emitting plate 30, the top of the decorative frame 60 is surrounded by the bottom of the light emitting plate 30 to form the light emitting area 602, the width of the light emitting area 602 is less than the opening width of the bottom of the lamp box 10, and / or the length of the light emitting area 602 is less than the opening length of the bottom of the lamp box 10;

[0071] The light source module 20 comprises the light emitting assembly 202, wherein the downward orthogonal projection of the light emitting assembly 202 is at least partially not coincided with the light emitting area 602, and the light emitting assembly 202 can obliquely irradiate to the light emitting plate 30 and emit from the light emitting port 601 through the light emitting area 602.

[0072] The bottom of the square lamp box 10 is provided with an opening, the light source module 20 is installed inside, the light emitting assembly 202 of the light source module 20 projects on the light emitting plate 30 and does not coincide with the projection of the light emitting port 601, the light emitting direction is inclined to irradiate, the width of the light emitting area 602 is smaller than the width of the bottom opening of the lamp box 10, and / or the length of the light emitting area 602 is smaller than the length of the bottom opening of the lamp box 10, and the light is emitted from the light emitting port 601 through the light emitting area 602, so that the light can be fully scattered and uniformly distributed on the light emitting plate 30, effectively avoiding the problem of unevenness and glare caused by direct light, improving the uniformity and softness of light emission, and more close to the lighting effect of natural sky, enhancing the visual comfort and reducing the glare phenomenon. The square lamp box 10 and the bottom opening design are convenient for the installation and layout of the internal light source module 20 and the light emitting assembly, the overall structure is compact, which is conducive to realizing better light emitting effect in limited space and improving the space utilization rate of the lamp; the design of the existing trapezoidal lamp box, parallelogram lamp box and other irregular lamp bodies is abandoned, the size is more flexible, and the regular box shape is more conducive to installation in limited roof space, improving the applicability of the lamp. The light emitting plate 30 and the decorative frame 60 of the light emitting assembly not only play a role in controlling the light emitting direction, but also can decorate the overall appearance of the lamp, so that it has better visual effect and decoration while meeting the functional requirements. The opening at the bottom of the lamp box 10 is also convenient for the installation and disassembly of the light emitting assembly, which is conducive to the maintenance, replacement or cleaning of the light source module 20 or the light emitting assembly when needed, and improves the maintainability of the lamp.

[0073] Specifically, in some possible embodiments, as shown in the drawings, Figures 1-4 The light emitting assembly includes the light emitting plate 30 and the decorative frame 60 arranged above and below, the decorative frame 60 forms the light emitting port 601 below the light emitting plate 30, the top of the decorative frame 60 cooperates with the bottom of the light emitting plate 30, the top of the decorative frame 60 forms the light emitting area 602 in the bottom of the light emitting plate 30, the light emitting direction is inclined to irradiate, the width of the light emitting area 602 is smaller than the width of the bottom opening of the lamp box 10, and / or the length of the light emitting area 602 is smaller than the length of the bottom opening of the lamp box 10, and the light is emitted from the light emitting port 601 through the light emitting area 602.

[0074] The decorative frame 60 in the embodiment of the application cooperates with the light emitting plate 30 to support the light emitting plate 30 and the lamp box 10, so that the structure is more stable; the top of the decorative frame 60 extends to the bottom of the light emitting plate 30 and is engaged with the bottom end of the light emitting plate 30, so that the light emitting plate 30 is divided into two parts of the light emitting area and the non-light emitting area, from Figure 4As shown, the light-emitting area of the light-emitting plate 30 is used for light emission, while the non-light-emitting area of the light-emitting plate 30 is not used for light emission. On the one hand, this can avoid the user directly observing the light-emitting assembly 202 of the light source module 20 through the right side of the light-emitting plate 30; on the other hand, the non-light-emitting area is located below the light-emitting assembly 202, and the light in this area is vertically incident on the light-emitting plate. The color of the light-emitting plate is white and bright, and the simulation of the blue sky is not good. Therefore, only using the light-emitting area for light emission can further improve the uniformity of light emission and the simulation effect of the blue sky.

[0075] Further, in some possible embodiments, four inner frame edges extending to the bottom of the light-emitting plate 30 are formed at the light-emitting opening 601 of the decorative frame 60.

[0076] The four inner frame edges are matched with the bottom of the light-emitting plate 30, and the extended ends of the four inner frame edges enclose the light-emitting area 602 at the bottom of the light-emitting plate 30.

[0077] Further, in some possible embodiments, the distance a between the plane where the light-emitting opening 601 of the bottom of the decorative frame 60 is located and the bottom of the light-emitting plate 30 is 25 mm≤a≤50 mm. Preferably, 30 mm≤a≤50 mm, and experiments have verified that the depth window effect is best when a is 30 mm-50 mm.

[0078] The decorative frame 60 in the embodiments of the present application is installed at the bottom opening of the light box 10 and keeps a distance, preferably 25 mm-50 mm, with the light-emitting plate 30. This design can form a window-like frame at the light-emitting opening 601, so that when the light passes through the light-emitting opening 601 of the decorative frame 60 from the light-emitting plate 30, a deep window effect is produced, the level and stereoscopic sense of light emission are enhanced, the simulated blue sky effect is more realistic, and the user's visual experience is improved.

[0079] The distance between the light-emitting opening 601 of the decorative frame and the light-emitting plate 30 helps the uniform distribution of light at the light-emitting opening 601. After passing through the light-emitting plate 30, the light can be better diffused and homogenized when passing through the light-emitting opening 601 of the decorative frame due to the existence of the distance, which reduces the problem of local light being too strong or too weak, makes the light emission softer and more uniform, and further optimizes the optical effect.

[0080] In addition, the decorative frame 60 in the embodiments of the present application can be fixed at the bottom opening of the light box 10 by magnet adsorption. This installation method enables the decorative frame 60 to closely adhere to the light box 10 and form a stable installation of the light-emitting plate 30. During use, even if subjected to a certain vibration or external force, the decorative frame 60 and the light-emitting plate 30 are not easy to loosen or fall off, which ensures the overall structural stability of the lamp.

[0081] Further, in some possible embodiments, as shown in FIG. 6, the decorative frame 60 is provided with a plurality of light-emitting openings 601, and the light-emitting plate 30 is provided with a plurality of light-emitting areas 602 corresponding to the light-emitting openings 601 of the decorative frame 60.Figures 1-4 As shown, one of the four inner frame edges on the same side as the light source module 20 is configured as an inclined edge 6021;

[0082] The inclined edge 6021 extends upward from the edge side of the light outlet 601 to the center side of the light box 10.

[0083] That is, one of the four inner frame edges of the decorative frame 60 corresponding to the light source module 20 is configured as an inclined edge 6021, and the inclined edge 6021 extends obliquely from the edge side of the light outlet 601 to the center side of the light box 10.

[0084] Preferably, as shown in the drawings, Figure 4 The inclination of the inclined edge 6021 is b, where 40°≤b≤60°, and the remaining three of the four inner frame edges are configured as straight edges 6022 extending upward, and the extension distance of the straight edge 6022 is a, where 25mm≤a≤50mm. Preferably, 30mm≤a≤50mm, and experiments have verified that a depth of 30mm-50mm is optimal for the window effect.

[0085] In the present embodiment, the one of the four inner frame edges corresponding to the light source module 20 is configured as an inclined edge 6021 in order to reduce the volume of the light body, particularly the width of the light body {i.e. Figure 4 the distance between the left and right sides of the light body}, while increasing the angle at which the user can view the light-emitting surface, so that the visual effect of the light-emitting surface is not too narrow; at the same time, the inclined edge 6021 is installed in the one of the inner frame edges corresponding to the light source module 20, which can better hide the light source and avoid direct viewing of the light source by the human eye.

[0086] The design of the straight edge 6022 with a depth of 25mm-50mm can highlight the window effect of the sky, and the straight edge 6022 will present a window reflection effect on the surface of the light-emitting plate, making the visual effect more profound. Experiments have verified that a depth of 30mm-50mm for the straight edge 6022 is optimal for the window effect.

[0087] Further preferably, the top ends of the four inner frame edges at the light outlet 601 of the decorative frame extend to the bottom end of the light-emitting plate 30 and are joined to the bottom end of the light-emitting plate 30, so that the light-emitting plate 30 is divided into a light-emitting area and a non-light-emitting area. Figure 4 From the perspective of the user, the light-emitting area of the light-emitting plate 30 is used for light emission, and the non-light-emitting area of the light-emitting plate 30 is not used for light emission, which can avoid the user directly observing the light-emitting assembly 202 of the light source module 20 through the right side of the light-emitting plate 30.

[0088] In combination with Figure 4 , in simple terms, if the Figure 4The length of the light box 10 in the left-right direction is the width of the light box, and it can be understood that the width of the light emitting area 602 in the embodiment of the application is less than the width of the opening at the bottom of the light box 10, so that when the light source module 20 is arranged at the corner position of the long side side plate and the top plate inside the light box 10, the projection of the light emitting assembly 202 of the light source module 20 in the vertical direction can be at least partially located outside the light emitting area 602. Of course, in some alternative embodiments, the length of the light emitting area 602 can also be set to be less than the length of the opening at the bottom of the light box 10, so that when the light source module 20 is arranged at the corner position of the short side side plate and the top plate inside the light box 10, the projection of the light emitting assembly 202 of the light source module 20 in the vertical direction can also be at least partially located outside the light emitting area 602.

[0089] It should be noted that, from Figure 4 the design width of the light emitting plate 30 is substantially the same as the design width of the light box 10, which is achieved by the separation of the four inner frame edges of the decorative frame 60 to realize part of the light emission and part of the non-light emission. However, in some alternative embodiments, the width of the light emitting plate 30 can also be set to be less than the width of the light box 10, that is, only the light emitting area 602 of the decorative frame is provided with a transparent material such as a Rayleigh scattering plate, and the non-light emitting area is provided with other non-transparent materials, which can also achieve the same technical effect, but relatively, the width of the light emitting plate 30 is designed to be the same as the width of the light box 10, which is simpler and faster in production and installation.

[0090] Further, in some possible embodiments, a ring of blocking ribs 10c is protruded on the inner wall of the side plate 10b of the light box;

[0091] The light emitting assembly further comprises a pressing frame 50 arranged between the bottom of the blocking rib 10c and the top of the decorative frame 60;

[0092] The light emitting plate 30 is arranged between the bottom of the blocking rib 10c and the top of the pressing frame 50 and is fixed by the pressing frame 50;

[0093] The blocking rib 10c on the inner wall of the side plate 10b of the lamp box 10 in the embodiment of the present application provides a stable support structure for the light-emitting plate 30. The light-emitting plate 30 is arranged on the blocking rib 10c and can effectively prevent displacement or loosening of the light-emitting plate 30 in the use process by the pressing effect of the pressing frame 50, thereby ensuring the relative position stability between the light-emitting plate 30 and the lamp box 10, and thus ensuring the overall optical performance and structural stability of the lamp. In addition, since the light-emitting plate 30 is stably pressed on the blocking rib 10c, the optical performance of the light-emitting plate 30 can remain stable even if the lamp is subjected to certain vibration or external force in the use process, and the light propagation and light-emitting effect will not be affected due to the position change or deformation of the light-emitting plate 30, thereby ensuring the optical performance consistency of the lamp in long-term use. Preferably, the blocking rib 10c is arranged on the inner wall of the lamp box side plate 10b and is designed in an integrated manner with the lamp box 10, without occupying additional space. The pressing frame 50 is adapted to the shape of the blocking rib 10c, so that the entire mounting structure is compact and will not increase the volume of the lamp body, thereby meeting the design trend of lightening, thinning and compactness of the lamp and being conducive to the arrangement and installation of the lamp body in limited installation space.

[0094] Preferably, the decorative frame 60 is connected together with the lamp box 10 in a magnetic attraction manner, and the pressing frame 50 presses and fixes the light-emitting plate 30 in a magnetic attraction manner with the lamp box 10 through the decorative frame 60.

[0095] Further, in some possible implementation manners, as shown in Figure 4 and Figure 7 , the light source module 20 further includes a heat dissipation assembly 201 and a light-emitting assembly 202.

[0096] The heat dissipation assembly 201 is fixedly installed on the top plate 10a and the side plate 10b of the lamp box 10, and the light-emitting assembly 202 is fixedly installed on the heat dissipation assembly 201.

[0097] In the embodiment of the present application, the heat dissipation assembly 201 is fixedly installed on the top plate 10a and the side plate 10b of the lamp box 10, and this installation manner enables the heat dissipation assembly 201 to fully utilize the space inside the lamp box 10 and increase the heat dissipation area. Meanwhile, the heat dissipation assembly 201 can effectively conduct heat to the shell, i.e., the lamp box 10, and can achieve good heat dissipation effect by means of the shell, thereby reducing the working temperature of the light-emitting assembly 202, prolonging the service life of the lamp and ensuring stable operation. The light-emitting assembly 202 is fixedly installed on the heat dissipation assembly 201, and this hierarchical fixing structure enables the light source module 20 to be more stably installed inside the lamp box 10. In the use process, displacement or loosening of the light source module 20 due to vibration or external force can be effectively reduced, thereby improving the overall reliability and durability of the lamp. Meanwhile, the fixed connection of the heat dissipation assembly 201 with the lamp box top plate 10a and the lamp box side plate 10b also provides a stable basis for the light-emitting assembly 202, thereby ensuring that the light source module 20 can maintain good optical performance when working.

[0098] Further, in some possible implementation manners, as shown in Figure 4 and Figure 7 the heat dissipation component 201 is provided with heat dissipation legs 2011 on the side away from the light emitting component 202;

[0099] The heat dissipation component 201 is installed on the top plate 10a and the side plate 10b of the light box 10 through the heat dissipation legs 2011, and a heat dissipation area 40 is enclosed between the heat dissipation component 201 and the top plate 10a and the side plate 10b of the light box 10. In this way, part of the heat generated by the light emitting component 202 can be directly transmitted to the light box 10 through the heat dissipation legs 2011, and the other part can be radiated into the heat dissipation area 40 and indirectly transmitted to the light box 10. Thus, the stability of the light source module 20 is ensured while the heat dissipation effect of the light source module 20 is improved.

[0100] Preferably, the heat dissipation legs 2011 are provided in plurality, and the positions where at least part of the heat dissipation legs 2011 are arranged are further provided with locking structures, wherein the heat dissipation component 201 is fixed on the light box 10 through the locking structures arranged at the positions of the heat dissipation legs 2011.

[0101] Further preferably, the locking structures mentioned above include locking screws arranged at the positions of the heat dissipation legs 2011.

[0102] In the embodiment of the present application, the locking structures fixed with the light box 10 are arranged at the positions of the heat dissipation legs 2011, which is on one hand convenient for the installation of the heat dissipation component 201, and on the other hand can avoid the damage of the strength of the light box 10.

[0103] Further preferably, the material of the light box 10 in the present application is metal material. Thus, since the heat dissipation legs 2011 are connected with the light box 10 together, the heat of the part of the light box 10 connected with the heat dissipation legs 2011 is large, and when the light box 10 is heated, the material will change in volume or size due to its thermal expansion characteristics. If the thermal stress exceeds the yield strength of the material, the light box 10 may be deformed or cracked. By arranging the locking structures at the positions with large thermal stress, the strength of the positions can be strengthened, so as to avoid the problem of deformation or cracking of the light box 10 due to excessive thermal stress.

[0104] Further, in some possible implementation manners, as shown in Figure 4 and Figure 7 the heat dissipation component 201 includes heat dissipation fins 2012, and the heat dissipation fins 2012 include top plate heat dissipation fins 20121 for connecting with the top plate 10a of the light box and side plate heat dissipation fins 20122 for connecting with the side plate 10b of the light box;

[0105] The top plate heat sink 20121 and the side plate heat sink 20122 are installed between the top plate 10a and the side plate 10b of the lamp box 10 at an obtuse angle, so that at least one of the top plate heat sink 20121 and the side plate heat sink 20122 can be inclined towards the light-emitting plate 30. The light-emitting assembly 202 is installed on the inclined heat sink surface, so that the light-emitting direction of the light-emitting assembly 202 can be inclined to irradiate towards the light-emitting plate 30.

[0106] The heat dissipation assembly 201 in the embodiment of the present application includes a top plate heat sink 20121 and a side plate heat sink 20122, which are installed between the top plate 10a and the side plate 10b of the lamp box 10 at an obtuse angle. This structural design makes the heat sink better adapt to the space layout inside the lamp box 10, increases the heat dissipation area, and improves the heat dissipation efficiency. At the same time, the inclined installation of the heat sink helps to more effectively conduct heat to the shell of the lamp box 10, and better dissipate heat through the shell, thereby reducing the working temperature of the light-emitting assembly 202 and prolonging the service life of the lamp. The light-emitting assembly 202 is installed on the inclined heat sink surface, so that the light-emitting direction of the light-emitting assembly 202 can be inclined to irradiate towards the light-emitting plate 30. This inclined light-emitting direction design helps to optimize the propagation path of light inside the lamp box 10, so that the light is more uniformly and effectively irradiated onto the light-emitting plate 30, thereby enhancing the light-emitting effect of the light-emitting plate 30, simulating a more realistic blue sky effect, and improving the visual experience of the user. The installation of the top plate heat sink 20121 and the side plate heat sink 20122 forms a stable support structure inside the lamp box 10. This structure not only stably fixes the heat dissipation assembly 201 and the light-emitting assembly 202, but also enhances the structural stability of the entire lamp body, reduces the displacement or loosening of components caused by vibration or external force during use, and improves the overall reliability and durability of the lamp.

[0107] Further, in some possible embodiments, as shown in Figure 4 The top plate heat sink 20121 is parallel to the top plate 10a of the lamp box 10, and the end of the top plate heat sink 20121 close to the side plate 10b of the lamp box is spaced apart from the side plate 10b of the lamp box;

[0108] The upper end of the side plate 10b heat sink is connected to the side of the top plate heat sink 20121 close to the side plate 10b of the lamp box, and the lower end is inclined downward and connected to the side plate 10b of the lamp box 10;

[0109] The light source module 20 is installed on the downwardly inclined extending side plate fin 20122, so that the light emitting direction of the light source module 20 is inclined to irradiate to the light emitting plate 30; of course, in some alternative embodiments, the top plate fin 20121 can be installed inclined to the top plate 10a, and the side plate fin 20122 can be installed parallel to the side plate 10b, and correspondingly, the light source module 20 can be installed on the inclined top plate fin 20121, which can also make the light emitting direction of the light source module 20 inclined to irradiate to the light emitting plate 30. But relatively, it is preferred that the light source module 20 is installed on the inclined side plate fin 20122, which has better light emitting effect.

[0110] Preferably, the top plate fin 20121 and the side plate fin 20122 are integrally formed;

[0111] Further preferably, the lamp box 10 is a metal box body;

[0112] Further preferably, the light emitting plate 30 is a swiss scattering plate.

[0113] The top plate fin 20121 in the embodiment of the application is installed parallel to the top plate 10a of the lamp box, and is spaced apart from the side plate 10b of the lamp box, and the side plate fin 20122 extends downwardly and inclinedly from one side of the top plate fin 20121 and is connected to the side plate 10b of the lamp box. This structure design enables the light emitting direction of the light source module 20 to be accurately inclined to irradiate to the light emitting plate 30 when the light source module 20 is installed on the downwardly inclined extending side plate fin 20122. This design optimizes the propagation path of light, so that light is more uniformly and effectively irradiated to the light emitting plate 30, thereby enhancing the light emitting effect of the light emitting plate 30 while ensuring the stability of the fin installation, simulating a more realistic blue sky effect, and improving the user's visual experience. Preferably, the light emitting plate 30 is a swiss scattering plate, which not only has good heat dissipation performance, but also plays a certain role in scattering and uniformizing light during light propagation, so that the light emitting is more soft and uniform, further improving the optical effect and avoiding the problem of uneven light and glare. The installation mode of the top plate fin 20121 and the side plate fin 20122 enables them to form a stable connection structure with the top plate 10a and the side plate 10b of the lamp box 10.

[0114] The top plate heat sink 20121 is installed parallel to the top plate 10a of the lamp box, and the side plate heat sink 20122 extends downwardly and obliquely from the top plate heat sink 20121 and is connected to the side plate 10b of the lamp box. This structure can effectively disperse and withstand various forces generated by the lamp during use, reduce the displacement or loosening of components caused by vibration or external force, and improve the overall stability and reliability of the lamp. Preferably, the top plate heat sink 20121 and the side plate heat sink 20122 are integrally formed. This integrally formed structure further enhances the integrity and firmness of the heat dissipation assembly 201, avoids the problems of reduced heat dissipation effect and unstable structure caused by splicing of multiple components, and improves the service life and performance of the heat dissipation assembly 201. The lamp box 10 adopts a metal box body. In addition to assisting heat dissipation, the metal material also has high strength and rigidity, which can provide good support and protection for the internal light source module 20, heat dissipation assembly 201 and other components, prevent the lamp from being deformed or damaged due to external impact or its own weight during use, and improve the overall quality and durability of the lamp.

[0115] Further, in some possible embodiments, as shown in FIG. 1, the side plate 10b includes two opposite long side plates and two opposite short side plates, and a rectangular cavity structure with open top and bottom is enclosed between the two long side plates and the two short side plates. The top opening of the rectangular cavity structure is connected with the top plate 10a, and the light emitting assembly is arranged at the bottom opening. Figures 1-4

[0116] Among them, the light source module 20 is installed at the corner position of the top plate 10a and the long side plate of the rectangular lamp box 10.

[0117] ​The side plates 10b of the light box 10 in the embodiments of the present application include two opposite long side plates and two short side plates, which enclose a rectangular cavity structure with openings at the top and bottom. This design makes the overall shape of the light box 10 regular and compact, facilitating installation in narrow or shape-limited ceiling spaces, such as between two wooden beams of a wooden beam structure ceiling in North America or in a keel ceiling structure in China, solving the problem of inconvenience in installation caused by the large size and irregular shape of the existing sky blue lamp. The light source module 20 is installed at the corner position of the top plate 10a and the long side plate of the rectangular light box 10. This layout makes full use of the space inside the light box 10, enabling the light source module 20 to be compactly installed within the light box 10, avoiding waste of space, and at the same time leaving sufficient space for other components such as the heat dissipation assembly 201, the light exit plate 30, etc., improving the space utilization of the entire lamp. The light source module 20 is installed at the corner position of the top plate 10a and the long side plate, and the light exit direction can accurately irradiate towards the light exit plate 30. This design optimizes the propagation path of light inside the light box 10, making the light more uniform and effectively irradiate onto the light exit plate 30, enhancing the light emitting effect of the light exit plate 30, simulating a more realistic blue sky effect, and improving the user's visual experience. The symmetry and regularity of the rectangular cavity structure help to evenly distribute the light inside the light box 10, reducing the problem of uneven light and glare. The light exit plate 30 is arranged at the bottom opening, which can better receive and scatter light, making the light exit softer and more uniform, further improving the optical effect. This design of the rectangular cavity structure of the light box 10 enables each component such as the light source module 20, the heat dissipation assembly 201, the light exit assembly, etc. to be relatively independently installed and maintained. During installation, the light source module 20 can be installed at the corner position of the top plate 10a and the long side plate first, and then the light exit assembly can be installed, which is simple and convenient. During maintenance or replacement of components, it can also be quickly disassembled and replaced, improving the maintenance efficiency. The relative independence between components improves the replaceability of components. When a component needs to be replaced, it is not necessary to disassemble or adjust the entire lamp on a large scale, but only the corresponding component needs to be replaced, reducing the maintenance cost and prolonging the overall service life of the lamp.

[0118] Of course, in some alternative embodiments, the light box 10 can also be arranged as a square box, but relatively speaking, in the embodiments of the present application, the light box 10 is a rectangular light box.

[0119] Further, in some possible embodiments, as shown in Figure 1 , Figure 4 and Figure 6 , the length of the light source module 20 installed at the corner position of the top plate 10a and the long side plate is adapted to the length of the long side plate;

[0120] Among them, as shown in Figure 6 andFigure 7 As shown, the light source module 20 includes a heat sink with a length adapted to the length of the long-side side plate, a light source plate with a length adapted to the length of the long-side side plate and mounted on the heat sink, and a plurality of light emitting sources distributed along the length direction of the light source plate.

[0121] In the embodiment, the length of the light source module 20 is adapted to the length of the long-side side plate. This design enables the light source module 20 to be closely mounted at the position where the top plate 10a and the long-side side plate meet, thereby making full use of the space inside the light box 10 and avoiding space waste. Meanwhile, this adaptive design also enables the light box 10 to maintain a compact square structure, which is convenient for arrangement and installation in limited installation space and meets the installation requirements of different ceiling structures. Moreover, the light source module 20 includes a light source plate with a length adapted to the length of the long-side side plate and a plurality of light emitting sources distributed along the length direction of the light source plate. This layout enables light to be uniformly distributed along the length direction of the long-side side plate, thereby making the light emission more uniform and avoiding the problem of excessively strong or weak local light, improving the light emitting effect of the light emitting plate 30, simulating a more realistic blue sky effect, and enhancing the visual experience of users. The plurality of light emitting sources are distributed along the length direction of the light source plate. This design enables the light emitting sources to work cooperatively when the light source module 20 is working, thereby making the light propagation path more stable and reducing the problem of optical performance degradation caused by failure of a single light emitting source or uneven light, thereby ensuring the consistency of the optical performance of the light fixture during long-term use. The length of the light source module 20 is adapted to the length of the long-side side plate, and the light source module 20 is mounted at the position where the top plate 10a and the long-side side plate meet. This mounting manner makes the position of the light source module 20 inside the light box 10 more stable. During use, the displacement or loosening of the light source module 20 caused by vibration or external force can be effectively reduced, thereby ensuring the stability of the optical performance and electrical connection of the light source module 20. The close fit between the light source module 20, the heat sink, and the top plate 10a and the long-side side plate of the light box 10 forms a stable overall structure. This structure can withstand various forces generated during use of the light fixture, thereby improving the overall reliability and durability of the light fixture and reducing the risk of failure or damage caused by unstable structure.

[0122] Further, in some possible embodiments, as shown in FIG. 1B, the light box side plate 10b includes a mounting side side plate for mounting the light source module 20 and a non-mounting side side plate for cooperating with the mounting side side plate to enclose the light box side plate. Figures 1-4

[0123] Preferably, the non-mounting side side plate of the light box 10 is coated with a light-absorbing material.

[0124] Preferably, the non-mounting side side plate of the light box 10 is coated with a light-absorbing material.

[0125] ​The non-mounting side side plate of the light box 10 in the embodiment of the present application is designed to be light-absorbing, preferably coated with light-absorbing material, which can effectively absorb the reflection and scattering of light inside the light box 10, reducing the generation of stray light. This helps to improve the light quality and transparency of the light-emitting plate 30, making the simulated blue sky effect clearer and more realistic, and improving the user's visual experience. By reducing stray light, more light can effectively pass through the light-emitting plate 30, improving the light-emitting efficiency and energy utilization efficiency of the lamp, so that the lamp can provide brighter and more uniform light under the same power. By reducing stray light, more light can effectively pass through the light-emitting plate 30, improving the light-emitting efficiency and energy utilization efficiency of the lamp, so that the lamp can provide brighter and more uniform light under the same power. In addition, the light-absorbing design and coating of the non-mounting side side plate make the light box side plate 10b unnecessary to be additionally optically adjusted or complicatedly assembled during installation, simplifying the installation process and improving the installation efficiency.

[0126] Further, in some possible embodiments, the lamp body includes a ceiling lamp, a panel lamp, a sky lamp, and a kitchen and bathroom integrated lamp. Specifically;

[0127] When the lamp body is used as a ceiling lamp, it can closely fit the ceiling to provide uniform lighting effect, and its heat dissipation design ensures stability during long-term use, especially suitable for places such as living rooms and bedrooms that require large-area lighting.

[0128] When the lamp body is used as a panel lamp, its light and thin light box 10 design and optimized light source module 20 layout make the lamp can be embedded in the ceiling or installed on the wall, etc. position, providing soft and uniform light, suitable for places such as offices and conference rooms that require high uniformity of light.

[0129] When the lamp body is used as a sky lamp, its unique optical design can simulate the effect of a blue sky, creating a light effect with a sense of hierarchy and depth through the cooperation of the decorative frame 60 and the light-emitting plate 30, suitable for places that require special atmosphere lighting, such as shopping malls and exhibition halls.

[0130] When the lamp body is used as a kitchen and bathroom integrated lamp, in special environments such as kitchens and bathrooms, this lamp body design can meet the requirements of waterproofing and moisture-proofing, while its compact structure and high-efficiency heat dissipation performance ensure stable operation in high-temperature and high-humidity environments, providing bright and comfortable lighting effects.

[0131] That is, the lamp body provided in the embodiment of the present application combines the reasonable layout of the light source module 20, the optimized design of the light-emitting plate 30, and the cooperation of the decorative frame 60. Whether in different types of lamps and lanterns such as ceiling lamps, panel lamps, or sky lamps, the lamp body can realize uniform, soft, and specific optical effect light emission, meet the diversified needs of lighting effects in different places, ensure the heat dissipation effect of the lamp in different use environments through the design of the heat dissipation assembly 201 and the optimization of the lamp box 10 structure, prolong the service life of the lamp, and improve the overall stability and reliability. The compact design of the lamp box 10 and the reasonable layout of the light source module 20 make the lamp body adapt to different installation space limitations. Whether it is embedded installation or surface installation, it can fully utilize the limited space to achieve good lighting effect. And whether it is a ceiling lamp, a panel lamp, or other types of lamps and lanterns, the installation method is relatively simple. Through screw, magnetic attraction, and other fixing methods, the installation and disassembly of the lamp are completed conveniently and quickly, reducing the difficulty and cost of installation and maintenance. At the same time, the components such as the light source module 20, the heat dissipation assembly 201, and the light-emitting plate 30 are relatively independent and easy to disassemble. When the lamp needs to be maintained, cleaned, or replaced, it can be quickly operated to improve the maintenance efficiency and prolong the overall service life of the lamp.

[0132] Embodiment 2

[0133] Further, the embodiment 2 of the present application provides a lamp assembly as shown in Figures 8-10 , which comprises a lamp body mounting frame 70 and the lamp body provided in the embodiment 1 of the present application.

[0134] The lamp body can be installed on the to-be-installed body through the lamp body mounting frame 70.

[0135] In the embodiment of the present application, the lamp body can be flexibly installed on various to-be-installed bodies such as ceilings, walls, suspended keels, etc. through the lamp body mounting frame 70. Whether it is a suspended ceiling of a North American wooden beam structure or a domestic keel suspended ceiling, it can be stably installed through a suitable mounting frame to adapt to different building structures and installation requirements in different regions.

[0136] Specifically, in some possible implementations, as shown in Figures 8 to 10 , the lamp body mounting frame 70 is provided with four groups, and the four groups of lamp body mounting frames 70 are arranged at the four corner positions of the square lamp box 10 and suspend the lamp box 10 through the hanging wire 80.

[0137] The four groups of lamp body mounting racks 70 in the embodiments of the present application are arranged at the four corner positions of the square lamp box 10. This multi-point support structure can effectively disperse the weight of the lamp box 10 and improve the overall installation stability of the lamp. In use, even if subjected to certain vibration or external force, the lamp is not prone to displacement or loosening, thereby ensuring the reliability and safety of the lamp. The lamp assembly can be flexibly installed on various to-be-installed bodies in a suspended manner by the hanging wires 80, such as a wood beam structure ceiling in North America or a domestic keel ceiling. This installation manner can adapt to the size and shape of different ceiling structures and ensure that the lamp can be stably installed in various environments.

[0138] Further, in some possible embodiments, as shown in Figure 8 The lamp body mounting rack 70 includes a longitudinally extending plate-shaped fixing rack and a plate-shaped hanging rack formed at the upper end of the plate-shaped fixing rack and extending transversely;

[0139] The plate-shaped fixing rack is formed with a transversely penetrating screw hole to enable the plate-shaped fixing rack to be fixed on a longitudinally extending to-be-installed body by a screw. The plate-shaped hanging rack is formed with a hanging wire 80 mounting position, at which one end of the hanging wire 80 is mounted, and the other end of the hanging wire 80 is connected to the lamp box 10.

[0140] Preferably, the four corner positions of the square lamp box 10 are provided with hanging codes 10d for being connected to the hanging wires 80. The lamp body mounting rack 70 is connected to the hanging codes 10d by the hanging wires 80 to suspend the lamp box 10.

[0141] In the embodiments of the present application, the lamp body mounting rack 70 is arranged at the four corner positions of the square lamp box 10, and four hanging codes 10d at the four corner positions of the lamp box 10 are connected by four hanging wires 80. This multi-point support structure can effectively disperse the weight of the lamp box 10 and improve the overall installation stability of the lamp. In use, even if subjected to certain vibration or external force, the lamp is not prone to displacement or loosening, thereby ensuring the reliability and safety of the lamp. The plate-shaped fixing rack is formed with a transversely penetrating screw hole to enable the plate-shaped fixing rack to be fixed on a longitudinally extending to-be-installed body by a screw. This design enables the lamp assembly to be flexibly installed on various different building structures and adapt to the installation requirements in different regions, such as a wood beam structure ceiling in North America and a domestic keel ceiling.

[0142] The plate-shaped fixing rack and the plate-shaped hanging rack are designed in a simple and clear structure. In installation, the plate-shaped fixing rack is only needed to be fixed on a to-be-installed body by a screw, and then one end of the hanging wire 80 is mounted at the hanging wire 80 mounting position of the plate-shaped hanging rack, and the other end is connected to the hanging code 10d of the lamp box 10. This design simplifies the installation steps, reduces the installation difficulty, and improves the installation efficiency.

[0143] When maintenance or replacement of the lamp is needed, the lamp can be conveniently removed from the body to be installed by loosening the screw or dismounting the hanging wire 80. This design facilitates maintenance personnel to quickly access various components inside the lamp, such as the light source module 20, the light emitting assembly, etc., for inspection, cleaning, repair or replacement operation, thereby improving the maintenance efficiency and reducing the maintenance cost. The plate-shaped design of the lamp body mounting rack 70 can make it flat with the surface of the body to be installed after installation, and the appearance is more simple and beautiful.

[0144] The connection mode of the hanging wire 80 and the hanging weight 10d is also relatively concealed, which does not excessively affect the overall appearance of the lamp, so that the lamp can better integrate into the decoration style in the use environment and improve the decoration effect. The plate-shaped fixing rack and the plate-shaped hanging bracket are made of a solid material and can withstand the weight of the lamp and various forces in the use process. The screw hole is also reasonably designed to ensure the firmness and reliability of the installation. The design of the hanging wire 80 installation position can ensure the stable connection between the hanging wire 80 and the mounting rack, prevent the lamp from falling off due to the loosening of the hanging wire 80, and improve the overall structural strength and durability of the lamp assembly.
