[0005] A lighting body of a fan lamp includes a shell, a back cover, a light source, a light source driver, a light guide plate, a reflective element and a diffuser plate. The shell and the back cover are enclosed to form a chamber. The light source, light guide plate, reflective element and diffuser plate are arranged in the chamber. The reflective element is arranged between the light guide plate and the back cover. The diffuser plate is located on the side of the light guide plate away from the back cover. The light source is arranged on the inner wall of the chamber. An rubber ring is arranged between the diffuser plate and the light guide plate. When the shell and the back cover are enclosed, the rubber ring forms a gap between the diffuser plate and the light guide plate.

[0006] The beneficial effects of the lighting lamp body of the fan lamp of the present invention are as follows: when the light emitted by the light source is guided to the diffuser plate through the light guide plate, the light needs to pass through the gap between the diffuser plate and the light guide plate. The refractive index of the gap is different from that between the diffuser plate and the light guide plate, and the light is refracted and reflected. After the interaction and diffusion between the refraction and multiple reflections, the light becomes softer and more uniform.

DETAILED DESCRIPTION

[0032] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0033] The specific structure of the lighting lamp body of the fan lamp of the utility model is as follows Figure 1 and Figure 3As shown, the device comprises a housing 4, a back cover 2, a light source 1, a light source driver 3, a light guide plate 5, a reflective element 6, an apron 7, and a diffuser 8. The housing 4 and back cover 2 enclose a chamber, in which the light source 1, light guide plate 5, reflective element 6, and diffuser 8 are disposed. The light source driver 3 is fixed to the side of the back cover 2 away from the housing 4, and the light source 1 is fixed to the inner wall of the chamber. The light source 1 and the light source driver 3 are electrically connected. When the housing 4 and back cover 2 are enclosed, the reflective element 6, the light guide plate 5, the apron 7, and the diffuser 8 are stacked together, pointing from the back cover 2 toward the housing 4. They are pressed against each other by the pressure of the housing 4 and back cover 2. The rubber ring 7 forms a gap between the diffuser plate 8 and the light guide plate 5; when the light emitted by the light source 1 is guided to the diffuser plate 8 through the light guide plate 5, the light needs to pass through the gap between the diffuser plate 8 and the light guide plate 5. The refractive index of the gap is different from that between the diffuser plate 8 and the light guide plate 5, and the light is refracted and reflected. After the interaction and diffusion between the refraction and multiple reflections, the light becomes softer and more uniform.

[0034] like Figure 3 As shown, in this embodiment, the light guide plate 5 and diffuser plate 8 are circular plates of equal diameter. The outer diameter of the rubber ring 7 is larger than the diameter of the circular plate, specifically 3mm larger, while the inner diameter of the rubber ring 7 is smaller than the diameter of the circular plate, specifically 3mm smaller. The rubber ring 7 is partially pressed between the light guide plate 5 and the diffuser plate 8, with the protruding portion blocking light and preventing leakage of the light source 1. The thickness of the rubber ring 7 is controlled to 3mm. When the housing 4 and the back cover 2 are enclosed, the rubber ring 7 is squeezed, and the gap is controlled to 2mm to 3mm. This improves the softness and uniformity of the light while preventing excessive width, which would cause light attenuation and reduce light intensity. In other embodiments, the thickness of the rubber ring is 1.5mm or 5mm, instead of 3mm. The thickness is mainly selected to match the intensity of the light source.

[0035] In this embodiment, the reflective component is reflective paper, which is laid flat on the side of the light guide plate 5 away from the diffuser plate 8. Reflective paper is lightweight and inexpensive. In other embodiments, if cost is not a concern, reflective sheeting may be used instead of reflective paper.

[0036] In this embodiment, the fan light's illuminating body also includes pearl cotton (EPM) 14, located between the rear cover 2 and the reflective paper. When the housing 4 and rear cover 2 are enclosed, the EPM 14 fills the gap between the rear cover 2 and the reflective paper, flattening and tightening the reflective paper. In other embodiments, the EPM may be omitted, or a similar soft material such as fiber or sponge may be used in its place.

[0037] like Figure 2As shown, in this embodiment, the housing 4 includes an annular wall 41 and an annular plate 42 disposed at the lower end of the annular wall 41. The annular wall 41 and the annular plate 42 are integrally formed. When the housing 4 and the rear cover 2 are enclosed, the annular plate 42 forms a stop for the diffuser 8. A slot 43 is provided on the interior of the annular wall 41, and a buckle 9 is provided on the rear cover 2. The housing 4 and the rear cover 2 are enclosed by the engagement between the buckle 9 and the slot 43. In other embodiments, the housing and the rear cover can be connected by screws, with screw holes provided on the housing and countersunk through holes in the rear cover. Screws pass through the countersunk through holes and are screwed into the screw holes to achieve connection.

[0038] like Figure 1 and Figure 3 As shown, in this embodiment, the light source 1 comprises a plurality of lamp beads, which are electrically connected to the light source driver 3 and are embedded in the inner wall of the annular wall 41. An annular band 13 is provided within the annular wall 41, and the lamp beads are embedded in the annular band 13. The lamp beads are evenly spaced along the circumference of the annular wall 41. When the housing 4 and the back cover 2 are enclosed, the lamp beads are located on the side of the rubber ring 7 closest to the back cover 2, within the projection of the light guide plate 5 on the inner wall of the annular wall 41. This facilitates light transmission to the light guide plate 5 while preventing light source 1 from leaking out and being emitted through gaps into the diffuser plate 8, which would reduce the softness and uniformity of the light. In other embodiments, the light source is a light strip, which is tightly attached to the inner wall of the annular wall.

[0039] When in use, the light source driver 3 makes the lamp beads emit light, and the light is emitted to the light guide plate 5. Under the transmission of the light guide plate 5 and the reflection of the reflective paper, the light is transmitted downward. When the light passes through the gap, the refractive index between the gap and the diffuser plate 8 and the light guide plate 5 is different, and the light is refracted and reflected. After the interaction and diffusion between refraction and multiple reflections, the light becomes softer and more uniform, and is emitted under the action of the diffuser plate 8.

[0040] The specific structure of the embodiment of the utility model fan lamp is as follows Figure 4 As shown, the fan lamp includes a lighting body 12, a fan 10 and a fixing frame 11. The lighting body and the fan of the fan lamp are respectively arranged on the fixing frame, and the fan is located above the lighting body of the fan lamp; the lighting body of the fan lamp has the same structure as the lighting body of the fan lamp in the above embodiment, and will not be described one by one here.

[0041] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
