[0031] It is understandable that, referring to Figures 1 to 6The ceiling lighting lamp of the present invention includes a base 100, a light guide cup 200 and a lamp body 300. The base 100 is connected to a plurality of mounting portions 130, which cooperate to be fixed to the ceiling; the light guide cup 200 is connected to the base 100, and the light guide cup 200 includes a transmissive portion 210 and a reflective portion 220. The reflective portion 220 is arranged around the transmissive portion 210, and the transmissive portion 210 is protruded away from the base 100. The wall surface of the transmissive portion 210 is provided with a plurality of protrusions 211, and the inner side wall of the reflective portion 220 is provided with a plurality of reflective prisms 221, and the plurality of reflective prisms 221 are arranged along the circumference of the transmissive portion 210; the lamp body 300 is fixedly connected to the base 100 and is located within the transmissive portion 210.

[0032] The base 100 is connected to a plurality of mounting portions 130. The base 100 is placed on the ceiling and fixed to the ceiling through the plurality of mounting portions 130. The light guide cup 200 and the lamp body 300 are both fixedly connected to the base 100. The light guide cup 200 includes a transmissive portion 210 and a reflective portion 220. The reflective portion 220 is arranged around the transmissive portion 210. The transmissive portion 210 is protruded away from the base 100 so that the lamp body 300 can be accommodated in the transmissive portion 210. The wall surface of the transmissive portion 210 is provided with a plurality of protrusions 211 so that the light emitted by the lamp body 300 can be refracted through the plurality of protrusions 211, thereby increasing the light intensity. The incident angle of the line, and then the light hits the reflecting part 220. The inner wall of the reflecting part 220 is provided with multiple reflecting prisms 221, and the multiple reflecting prisms 221 are arranged along the circumference of the transmitting part 210. The multiple reflecting prisms 221 can increase the reflection angle of the light and increase the number of reflections of the light, so that the illumination angle can be increased after the light passes through the transmitting part 210 and the reflecting part 220, and the uniformity of the illumination can be improved, so that the light emitted by the ceiling lighting is softer, and the user experience is enhanced.

[0033] It should be noted that the lamp body 300 can be accommodated within the transmissive portion 210, so that light emitted by the lamp body 300 can first pass through the transmissive portion 210, allowing the light to be refracted by the protrusions 211 to adjust the angle of illumination of the light, thereby increasing the angle of the light incident on the reflective portion 220, reducing the amount of light directly emitted through the transmissive portion 210, and improving the uniformity of illumination. Multiple reflective prisms 221 are arranged on the inner sidewall of the reflective portion 220, so that light entering from the reflective portion 220 can be emitted through the multiple reflective prisms 221. The reflective prisms 221 can increase the reflection angle of the light, thereby making the emitted light softer and improving the uniformity of the light.

[0034] The outer walls of the transmissive portion 210, protrusions 211, and reflective portion 220 are made of transparent materials such as acrylic and glass to allow light from the lamp body 300 to pass through smoothly. The inner walls of the reflective prisms 221 are electroplated with a layer of chrome, nickel, or other materials, allowing light to be reflected through them. When closed, the reflective prisms 221 reflect the surrounding colors, enhancing the aesthetics of the ceiling light.

[0035] It is understandable that, referring to Figures 3 to 5 The protrusions 211 are arranged on the inner bottom wall of the transmissive portion 210. When light emitted from the lamp body 300 passes through the bottom wall of the transmissive portion 210, it can be refracted by the multiple protrusions 211, thereby improving the uniformity of the light. When light emitted from the lamp body 300 passes through the side walls of the transmissive portion 210, the light can directly pass through the transmissive portion 210 and hit the reflective portion 220, thereby reducing light loss and improving the efficiency of the ceiling lighting.

[0036] It should be noted that the light emitted by the lamp body 300 is more concentrated in the middle part. By setting the protrusion 211 on the inner bottom wall of the transmission part 210, the light of the lamp body 300 is guided to irradiate the reflection part 220, reducing the direct emission of light and improving the uniformity of illumination.

[0037] Specifically, refer to Figures 3 to 5 The multiple protrusions 211 are arranged continuously, and the multiple protrusions 211 are distributed all over the inner bottom wall of the transmissive portion 210. By arranging the multiple protrusions 211 continuously and distributing them all over the inner bottom wall of the transmissive portion 210, light emitted from the lamp body 300 is refracted by the multiple protrusions 211 when passing through the bottom wall of the transmissive portion 210, reducing direct light emission, improving light uniformity, and softening the light. Furthermore, the multiple protrusions 211 distributing all over the inner bottom wall of the transmissive portion 210 can reduce direct light emission from the lamp body 300, reduce glare caused when a user looks directly at the ceiling light, reduce light irritation to the user's eyes, and improve the user experience.

[0038] It is understandable that, referring to Figures 3 to 5 The wall of the protrusion 211 is spherical. By setting the protrusion 211 to be spherical, the refraction angle of the light emitted by the lamp body 300 when it enters the protrusion 211 can be increased, thereby increasing the incident angle of the light, allowing more light to be directed to the reflective portion 220, improving the illumination uniformity of the ceiling lighting, and enhancing the user experience.

[0039] It is understandable that, referring to Figure 3 、 Figure 4 and Figure 6The multiple reflective prisms 221 are arranged continuously and are arranged around the circumference of the transmissive portion 210. The multiple reflective prisms 221 cooperate to scatter the light directed toward the reflective portion 220, thereby increasing the light emission angle, improving the uniformity of the light, and achieving floodlighting, thereby improving the user experience of the ceiling lighting.

[0040] Specifically, refer to Figure 3 、 Figure 4 and Figure 6 The cross-sectional shape of the reflective prism 221 is triangular. By setting the cross-sectional shape of the reflective prism 221 to be triangular, when light strikes the reflective prism 221, the light can be reflected between the two side walls of the reflective prism 221, thereby increasing the number of light reflections and allowing the light to be emitted at a larger light output angle, thereby improving the floodlighting effect of the ceiling lighting and enhancing the user experience.

[0041] In addition, the cross-sectional shape of the reflective rib 221 may also be rectangular, circular, etc., which is not limited here.

[0042] It is understandable that, referring to Figure 3 The reflective portion 220 has an arc-shaped cross section. By setting the reflective portion 220 to have an arc-shaped cross section, light reflected by the reflective portion 220 can be directed away from the transmissive portion 210, thereby reducing light loss and improving the brightness and efficiency of the ceiling lighting.

[0043] It is understandable that, referring to Figures 1 to 3 The base 100 includes a barrel 110 and a baffle 120. The baffle 120 is connected to the open end of the barrel 110. The light guide cup 200 and the lamp body 300 are both installed in the barrel 110. The mounting portion 130 is connected to the side wall of the barrel 110. The base 100 includes the barrel 110 and the baffle 120. By sequentially installing the lamp body 300 and the light guide cup 200 in the barrel 110 and then connecting the baffle 120 to the open end of the barrel 110, the assembly of the ceiling light is facilitated, improving production convenience.

[0044] It is understandable that, referring to Figure 3 The baffle 120 is provided with a connecting ring 121 on one side close to the cylinder 110, and the connecting ring 121 is inserted into the cylinder 110. The connecting ring 121 is provided on the side of the baffle 120 close to the cylinder 110, and the connecting ring 121 is inserted into the cylinder 110, so that the cylinder 110 and the baffle 120 can be conveniently connected together, thereby improving the convenience of assembly.

[0045] It should be noted that the outer diameter of the connecting ring 121 is greater than or equal to the inner diameter of the cylinder 110 , so that the connecting ring 121 can abut against the inner wall of the cylinder 110 , thereby stabilizing the baffle 120 on the cylinder 110 .

[0046] Specifically, refer to Figure 1 The mounting portion 130 includes a support plate 131 and a torsion spring 132. The support plate 131 is rotatably connected to the cylinder 110. The torsion spring 132 is disposed between the cylinder 110 and the support plate 131. One end of the torsion spring 132 abuts the cylinder 110, and the other end of the torsion spring 132 abuts the support plate 131, thereby driving the support plate 131 to rotate toward the baffle 120. The support plate 131 is rotatably connected to the cylinder 110. One end of the torsion spring 132 abuts the cylinder 110, and the other end abuts the support plate 131. The torsion spring 132 drives the connecting plate to rotate toward the baffle 120, allowing the baffle 120 to be pressed against the ceiling, thereby improving the installation convenience of the ceiling light.

[0047] It should be noted that when installing the ceiling lighting, first move the support plate 131 to compress the torsion spring 132, then insert the cylinder 110 into the ceiling, and use the torsion spring 132 to drive the support plate 131 to reset, so that the support plate 131 rotates in the direction close to the baffle 120, so that the baffle 120 can abut against the ceiling, thereby enabling the ceiling lighting to be stabilized on the ceiling and improving the convenience of installation.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
