[0025] The present utility model provides a lighting fixture. Please refer to Figures 1 to 4 , the lighting fixture includes: a chassis assembly 100, a side frame assembly 200, a light source circuit board 300, a surface light source light output board 400, and a side light source light output member 500.

[0026] The chassis assembly 100 has an opposite mounting side and a light output side.

[0027] In some optional embodiments, the chassis assembly 100 includes: a chassis 110 and a chassis cover assembly 120.

[0028] The chassis 110 and the chassis cover assembly 120 are fixed to each other. The chassis 110 is disposed on the light output side, and the chassis cover assembly 120 is disposed on the mounting side. The chassis cover assembly 120 covers the chassis 110 and is used to be fixed to the installation environment. Among them, the installation environment can be a ceiling, a wall, etc.

[0029] The side frame assembly 200 surrounds the periphery of the chassis assembly 100 and is fixed to the chassis assembly 100. The side frame assembly 200 extends from the mounting side to the light output side.

[0030] In some optional embodiments, the side frame assembly 200 includes: a side wall frame 210 and a side wall flange 220.

[0031] Among them, the side wall frame 210 surrounds and abuts against the periphery of the chassis assembly 100, and the side wall frame 210 extends from the mounting side to the light output side. The side wall flange 220 is connected to one end of the side wall frame 210 facing the light output side, and the side wall flange 220 extends inwards from its connection with the side wall frame 210.

[0032] In some optional embodiments, a plurality of circumferentially surrounding first reinforcing ribs 211 are provided on the side wall frame 210. The first reinforcing ribs 211 extend inwards from the inner side wall of the side wall frame 210, and the plurality of first reinforcing ribs 211 are uniformly arranged along the axial direction. Through the plurality of first reinforcing ribs 211, the structural strength of the side wall frame 210 is effectively enhanced, and thus, it is beneficial to enhance the overall structural strength of the side frame assembly 200.

[0033] In some optional embodiments, a second reinforcing rib 221 extending towards the chassis assembly 100 is provided on the side wall flange 220. Through the second reinforcing rib 221, the structural strength of the side wall flange 220 is effectively enhanced, and thus, it is beneficial to enhance the overall structural strength of the side frame assembly 200

[0034] The light source circuit board 300 is fixed to the light output side of the chassis assembly 100. The light source circuit board 300 includes a surface light source area 301 and a linear light source area 302 surrounding the surface light source area 301.

[0035] Further, a plurality of surface light source beads 310 are provided on the surface light source area 301, and a plurality of linear light source beads 320 are provided on the linear light source area 302. Moreover, the light source circuit board 300 further includes a fixing area located between the surface light source area 301 and the linear light source area 302.

[0036] In some alternative embodiments, the plurality of linear light source beads on the linear light source area 302 are arranged uniformly in the circumferential direction. Thus, the width of the linear light source area 302 can be reduced, and the linear light source area 302 can have a relatively uniform light-emitting effect.

[0037] The surface light source light-emitting plate 400 is fixedly connected to the chassis assembly 100 and is correspondingly arranged with the surface light source area 301, such that the orthographic projection of the surface light source area 301 is within the range of the surface light source light-emitting plate 400. The light emitted from the surface light source area 301 is emitted through the surface light source light-emitting plate 400.

[0038] In some alternative embodiments, the surface light source light-emitting plate 400 includes a surface light transparent plate and a surface light diffusing plate arranged in an overlapping manner, wherein the surface light diffusing plate is located between the surface light transparent plate and the light source circuit board 300.

[0039] The light emitted through the side light source light-emitting member 500 is at least partially projected onto the surface light transparent plate and is reflected by the surface light transparent plate to simulate the window shadow effect formed on the window when one side of the window is illuminated by sunlight, such that it appears to the human eye to have a sense of depth and permeability.

[0040] Further, the surface of the surface light transparent plate facing the surface light diffusing plate is a mirror surface, and the reflectivity of the mirror surface to light is greater than the transmittance of light, thereby restricting external light from entering the surface light transparent plate from the light-emitting surface of the surface light transparent plate.

[0041] In some alternative embodiments, the material of the surface light transparent plate can be an inorganic material, and the inorganic material can be quartz glass. The surface light transparent plate can also be made of an organic material, and the organic material can be a polymer transparent material such as plexiglass.

[0042] In some alternative embodiments, a very thin one-way film layer, such as tin, silver, or aluminum, is plated on the light-emitting surface of the surface light transparent plate through a crystal plating process to form a one-way film layer. The crystal plating process can make the one-way film layer have a relatively high smoothness. In other embodiments, the surface light transparent plate can be selected according to actual circumstances and is not limited herein. The thickness of the one-way film layer can be adjusted according to actual circumstances. When the thickness of the one-way film layer increases, its reflectivity and transmittance will change, and the effect of one-way perspective is achieved by using the reflectivity being higher than the transmittance.

[0043] The side light-emitting component 500 is fixedly connected to the side frame assembly 200 and is correspondingly arranged with the linear light source area 302. The side light-emitting component 500 extends from the surface light source area 301 towards the installation side and protrudes relative to the surface light source light-emitting plate 400.

[0044] In the lamp of the embodiment of the present utility model, since the light source circuit board 300 includes a surface light source area 301 and a linear light source area 302 surrounding the surface light source area 301, and further includes a surface light source light-emitting plate 400 corresponding to the surface light source area 301 and a side light-emitting component 500 corresponding to the linear light source area 302, the number of connection wires between the driving circuit and the surface light source and the linear light source is small, the problem of shadows generated when the wire passes through the surface light is improved, and the visual effect of the light is enhanced.

[0045] In some alternative embodiments, there is a panel pressing ring 600 between the surface light source light-emitting plate 400 and the light source circuit board 300.

[0046] The panel pressing ring 600 is arranged around the surface light source area 301. One end of the panel pressing ring 600 facing the installation side is fixed to the fixing area, and one end of the panel pressing ring 600 facing the light-emitting side and the side light-emitting component 500 jointly clamp the edge of the surface light source light-emitting plate 400, so that the surface light source light-emitting plate 400 is fixedly connected to the chassis assembly 100.

[0047] Through the panel pressing ring 600, the fixing of the surface light source light-emitting plate 400 can be realized in combination with the side light-emitting component 500. In addition, there is a fixing area between the surface light source area 301 and the linear light source area 302, and one end of the panel pressing ring 600 facing the installation side is fixed to the fixing area. Therefore, the collision and damage to each electronic component on the light source circuit board 300 caused by the fixing of the panel pressing ring 600 to the surface light source light-emitting plate 400 are avoided. Moreover, since one end of the panel pressing ring 600 facing the installation side is fixed to the fixing area, that is to say, relative to the part of the side light-emitting component 500 between the light source circuit board 300 and the surface light source light-emitting plate 400, the panel pressing ring 600 is located on the inner side close to the surface light source area 301. Therefore, the panel pressing ring 600 can also play a light-shielding role, better avoiding the light of the linear light source area 302 from entering the area corresponding to the surface light source light-emitting plate 400 from the area between the light source circuit board 300 and the surface light source light-emitting plate 400 and incident on the light-emitting plate 400, so as to reduce the interference with the light-emitting effect of the lamp and make the light-emitting effect of the lamp closer to the expected target.

[0048] In some alternative embodiments, the side light-emitting component 500 includes a linear light source light guide plate 510 and a linear light source diffusing plate 520.

[0049] Among them, the linear light source light guide plate 510 extends from the surface light source area 301 towards the installation side and protrudes relative to the surface light source light output plate 400. The linear light source diffusion plate 520 is attached to the inner side wall of the linear light source light guide plate 510, and the top end of the light source diffusion plate 520 and the panel pressing ring 600 jointly clamp the edge of the surface light source light output plate 400. The light emitted from the surface light source area 301 is guided by the linear light source light guide plate 510, better guided to the linear light source diffusion plate 520, and emitted under the surface light source light output plate 400 through the linear light source diffusion plate 520 to achieve the window shadow simulation effect, and at the same time, bring a better lighting effect.

[0050] Furthermore, one end of the light source light guide plate 510 and the light source diffusion plate 520 facing the light output side both abut against the side wall flanging 220. Therefore, combining the installation positions of the panel pressing ring 600, the light source light guide plate 510, and the light source diffusion plate 520, and the side wall flanging 220 extending inwards from their connection with the side wall frame 210, the common fixation of the surface light source light output plate 400 and the side light source light output member 500 is achieved.

[0051] In some alternative embodiments, the linear light source light guide plate 510 abuts against the end of the first reinforcing rib 211. Thus, the setting of the first reinforcing rib 211 not only increases the structural strength but also helps to fix the linear light source light guide plate 510. And since several first reinforcing ribs 211 are evenly arranged along the axial direction, there is a space between the linear light source area 302 and the side light source light output member 500 and the side wall frame 210, which is also beneficial for heat dissipation.

[0052] In some alternative embodiments, the second reinforcing rib 221 and the first reinforcing rib 211 are located on the same side of the linear light source light guide plate 510, and the second reinforcing rib 221 abuts against the linear light source light guide plate 510. Thus, the setting of the second reinforcing rib 221 not only increases the structural strength but also helps to limit the position of the linear light source light guide plate 510.

[0053] In some alternative embodiments, the linear light source diffusion plate 520 is annular. The linear light source diffusion plate 520 is at least divided into a connected first area and a second area in the circumferential direction. There is at least one inclined boundary line between the first area and the second area. The linear light source light guide plate 510 is located in the first area or the second area, and the projection of one end of the linear light source light guide plate 510 in the circumferential direction on the linear light source diffusion plate 520 coincides with the inclined boundary line. Thus, a clear window shadow effect can be formed.

[0054] In some alternative embodiments, the panel pressing ring 600 includes: a side pressing ring 610, a first side pressing and fixing portion 620, and a second side pressing and fixing portion 630.

[0055] Among them, the side pressing ring 610 fits on the part of the linear light source light guide plate 510 between the light source circuit board 300 and the surface light source light output plate 400 to better block light.

[0056] In addition, the first side pressing and fixing portion 620 is bent and connected to one end of the side pressing ring 610 facing the light source circuit board 300, and abuts against the fixing area. The second side pressing and fixing portion 630 is bent and connected to one end of the side pressing ring 610 facing the surface light source light-emitting plate 400, and abuts against the edge of the surface light source light-emitting plate 400.

[0057] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
