[0037] Reference Figure 1 As shown, this is a screwless exposed ceiling light 1000 provided in an embodiment of the present utility model.
[0038] Reference Figure 2 As shown, the screwless exposed ceiling light 1000 includes a housing 100, an outer frame 200, a diffuser plate 300, a crystal plate 400, and a light panel 500.
[0039] Reference Figure 2 and Figure 4 As shown, the outer shell 100 has a circular structure. The lower end of the outer shell 100 has a downwardly extending annular boss 120, which forms an opening 110. The outer peripheral wall of the annular boss 120 has a convex ring 130 extending circumferentially therefrom. The lower end of the annular boss 120 has multiple downwardly extending first positioning posts 140, which can be arranged at intervals along the circumference of the annular boss 120. The outer frame 200 has a ring-shaped structure. The upper end of the outer frame 200 has a downwardly extending overlapping boss 210, which extends circumferentially along the outer frame 200. The lower end of the overlapping boss 210 abuts against the upper end of the convex ring 130. The lower end of the outer frame 200 has a horizontally extending support boss 220, which extends circumferentially along the outer frame 200. The lamp panel 500 is installed inside the housing 100. The diffuser plate 300 is located at the opening 110 and below the lamp panel 500. The prismatic plate 400 is located below the diffuser plate 300. The diffuser plate 300 is located at the opening 110, and its outer edge overlaps with the support boss 220. The lower end of the annular boss 120 abuts against the upper end of the diffuser plate 300. A first positioning hole 310 is provided near the outer edge of the diffuser plate 300, and the first positioning hole 310 cooperates with the first positioning post 140. The prismatic plate 400 is located between the diffuser plate 300 and the support boss 220. A second positioning hole 410 is provided near the outer edge of the prismatic plate 400, and the second positioning hole 410 cooperates with the positioning post.
[0040] When installing the screwless exposed ceiling light 1000 of this embodiment, first assemble the diffuser plate 300 and the rhombus plate 400 to the outer shell 100 from bottom to top, so that the first positioning post 140 passes through the first positioning hole 310 and the second positioning hole 410. Then, assemble the outer frame 200 to the outer shell 100 from bottom to top. The support boss 220 of the outer frame 200 supports the diffuser plate 300 and the rhombus plate 400. The lower end of the annular boss 120 of the outer shell 100 presses against the upper end of the diffuser plate 300, and the lower end of the first positioning post 140 abuts against the support boss 220. The upper end of the outer frame 200... The overlapping boss 210 overlaps on the convex ring 130, and the convex ring 130 supports the overlapping boss 210. It can be understood that the upper and lower ends of the outer frame 200 are fastened to the outer shell 100. In this way, the outer frame 200 can be limited, and the connection stability is better. Compared with the traditional solution, screw fixing can be eliminated, and the appearance effect is better. Since the annular boss 120 presses down on the diffuser plate 300 and the prismatic plate 400, and the diffuser plate 300 and the prismatic plate 400 are limited by the first positioning post 140, the diffuser plate 300 and the prismatic plate 400 are not easy to sag downwards.
[0041] In some embodiments, the outer frame 200 may undergo local deformation. For example, the outer frame 200 is a plastic part. When the upper and lower ends of the outer frame 200 are fastened to the outer shell 100, the outer frame 200 is tensioned, which can maintain connection stability. The outer shell 100 is made of aluminum, which can be understood as an aluminum shell. Aluminum shells have high processing precision and high structural strength.
[0042] Refer to Figure 2 and Figure 5 As shown, according to some embodiments of this utility model, the screwless exposed ceiling light 1000 further includes a connecting ring 600 and a light-emitting circular plate 700. The connecting ring 600 has an annular structure and surrounds the outer periphery of the light panel 500. The upper end of the connecting ring 600 is fixedly connected to the light panel 500 by fasteners. The connecting ring 600 and the light-emitting circular plate 700 can be light-transmitting components. The light-emitting circular plate 700 is provided with an upwardly extending buckle 710, which has a cantilever structure. Plate 700 is fastened to connecting ring 600 by buckle 710. Connecting ring 600 also has a cantilever structure similar to buckle 710 for fastening to buckle 710. Diffuser plate 300 and prism plate 400 are both ring-shaped structures. The inner periphery of prism plate 400 overlaps above light-emitting circular plate 700. Light-emitting circular plate 700 can support diffuser plate 300 and prism plate 400. Connecting ring 600 presses down on diffuser plate 300 and prism plate 400.
[0043] Reference Figure 6As shown in some embodiments of this utility model, both the diffuser plate 300 and the rhombic plate 400 have third positioning holes 320 extending in the vertical direction on their inner periphery. The lower end of the connecting ring 600 has multiple downward-extending second positioning posts 610. These second positioning posts 610 can be arranged at intervals along the circumference of the connecting ring 600. The second positioning posts 610 are positioned and engaged with the third positioning holes 320, preventing the diffuser plate 300 and the rhombic plate 400 from rotating relative to the connecting ring 600, thus providing a limiting function. Through the limiting engagement of the second positioning posts 610 with the first positioning posts 140 at both the inner and outer positions, the diffuser plate 300 and the rhombic plate 400 can be pressed tightly at both the inner and outer positions, further preventing the diffuser plate 300 and the rhombic plate 400 from sagging.
[0044] Reference Figure 6 As shown, according to some embodiments of the present invention, the outer peripheral wall of the second positioning post 610 is provided with reinforcing ribs 611, which can improve the structural strength of the second positioning post 610. The lower end of the reinforcing ribs 611 abuts against the upper end of the diffuser plate 300, so that the reinforcing ribs 611 can press down on the diffuser plate 300 and the rhombic plate 400 to prevent the diffuser plate 300 and the rhombic plate 400 from bending downward.
[0045] Reference Figure 6 As shown, according to some embodiments of the present invention, the lower end of the connecting ring 600 is provided with an annular positioning groove 620, and the upper end of the light-emitting circular plate 700 is provided with an annular positioning boss 720. The annular positioning boss 720 and the annular positioning groove 620 are positioned and engaged, which can facilitate assembly. The buckle 710 for fastening the light-emitting circular plate 700 and the connecting ring 600 is provided at the upper end of the annular positioning boss 720.
[0046] According to some embodiments of this utility model, the cross-section of the diffuser plate and the rhombic plate is wavy, which can make the emitted light more uniform and the irradiated area larger.
