Description

Technical Field

[0001] This utility model relates to a ceiling light that can emit light from the back. Background Technology

[0002] Ceiling lights are a type of lighting fixture typically installed on the ceiling of a house. Existing ceiling lights generally emit downward-scattering light. For example, in a room, this illumination method creates a stark contrast in light intensity between the lower and upper parts of the room, usually with the lower part brighter and the upper part darker. The illumination or display effect is not perfect, resulting in uneven lighting within a given space. This is especially problematic for ceiling spaces with distinctive features, as the light from existing ceiling lights can directly cover or obscure them, affecting the visual experience. Furthermore, existing ceiling lights themselves have poor display effects and limited decorative impact on the surrounding environment. Therefore, it is necessary to develop a ceiling light that emits light from the back to solve the problems encountered in the use of existing ceiling lights. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a back-illuminated ceiling light with a novel structure, easy installation, and the ability to improve the illumination effect, making the light illumination more uniform in a certain area, improving the visual effect, and facilitating a better display of the environment in the area. It is practical and widely used.

[0004] To solve the above problems, the present invention adopts the following technical solution: A back-illuminated ceiling light includes a mounting plate, a back cover, a face ring, a power driver, wiring terminals, a DIP switch, a diffuser plate, reflective paper, a light guide plate, a first light strip, and a second light strip. The mounting plate and the back cover, as well as the back cover and the face ring, are connected by snap-fit. The first and second light strips are both annular structures, with the first light strip disposed on the inner side of the face ring and the second light strip disposed on the inner side of the back cover. The diffuser plate, reflective paper, and light guide plate are arranged sequentially from bottom to top and are located on the inner side of the first light strip; the back cover is made of transparent or semi-transparent plastic.

[0005] Preferably, the back cover has circumferentially distributed slots, and the inner circumferential side of the face ring has circumferentially distributed buckles that cooperate with the slots, and the slots and buckles are connected.

[0006] Preferably, the mounting plate is provided with mounting holes and wire holes. There are three mounting holes, which are equidistantly distributed around the wire holes, and the mounting holes are in a ring structure.

[0007] Preferably, the bottom of the mounting plate is provided with an annular extension structure, and a plurality of wedge-shaped blocks are distributed circumferentially on the annular extension structure; the middle of the back cover is recessed to the bottom to form a circular boss, and a groove is formed on the inner side of the circular boss. Limiting steps that cooperate with the wedge-shaped blocks are distributed around the groove. The limiting steps are connected to the wedge-shaped blocks, and the number of limiting steps is the same as the number of wedge-shaped blocks.

[0008] Preferably, the circular boss is provided with multiple wire-threading grooves.

[0009] Preferably, the second light strip is arranged around the circular boss, and the installation of the second light strip is completed by the function of the circular boss.

[0010] Preferably, the mounting plate is fully embedded in the groove, which makes the upper surface of the ceiling light flat, facilitates installation, and also makes the ceiling light have good overall integrity.

[0011] The beneficial effects of this utility model are: 1. The wiring channel facilitates the connection of wires and also helps dissipate heat, thus improving the working environment of the light strip.

[0012] 2. By using wedge blocks and limiting steps, and through the rotational interlocking action between the wedge blocks and the limiting steps, the ceiling light can be installed conveniently, and disassembly is also extremely convenient.

[0013] 3. The design of the ring-shaped mounting holes facilitates the fixing of the mounting plate, thus making the installation of the entire ceiling light easier. At the same time, the design of the wire hole facilitates the insertion and connection of the power cord.

[0014] 4. Through the action of the diffuser plate, reflective paper, and light guide plate, the light illumination becomes more uniform and softer.

[0015] 5. The design of the slot and buckle structure facilitates the connection between the face ring and the back cover, increasing the ease of assembly.

[0016] 6. By using transparent or semi-transparent plastic material for the back cover, and adding the second light strip, the light generated by the second light strip can penetrate the back cover and shine horizontally and upward, improving the illumination effect of the ceiling light, facilitating better display of local spaces, and enhancing the user experience.

[0017] 7. With its novel structure and convenient installation, it can improve the lighting effect, making the lighting in a certain area more uniform, enhancing the visual effect, and facilitating a better display of the environment in the area. It is practical and widely applicable. Attached Figure Description
