Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to a novel luminous backboard lamp structure. Background Art

[0002] Ceiling lamps are lamps that are attached to or embedded in the ceiling of the roof. Like chandeliers, they are also the main lighting equipment in the room and are widely used in various places such as homes, offices, and entertainment venues. Traditional ceiling lamps are usually composed of a lamp panel, a light source, and a lampshade. The light source of traditional ceiling lamps is generally an energy-saving lamp tube. Due to the pollution caused by the production process and after use of energy-saving lamp tubes, their power consumption is still relatively large compared with LEDs. LEDs are mercury-free, non-toxic, electromagnetically resistant, and free of harmful rays. They are energy-saving and environmentally friendly, and have a long service life. Therefore, existing ceiling lamps are gradually replacing energy-saving lamp tubes with LEDs as light sources. Traditional ceiling lamps generally have the phenomenon of uneven light output. For example, long-term use in a space with insufficient illumination will cause great damage to human vision.

[0003] To this end, a LED ceiling lamp with uniform light output, with the announcement number "CN219222146U", includes a lamp housing, including a main housing and a diffusion plate, wherein the diffusion plate is arranged on the opening of the main housing; a light source, which is a ring-shaped light strip, which is installed on the inner wall of the main housing and is arranged along the inner wall of the main housing; a light guide plate, which is installed in the accommodating cavity of the main housing, and the light guide plate is provided with a plurality of protrusions to achieve light guidance; a reflector, which is arranged on the light guide plate; a cushion layer, which is arranged on the reflector; wherein the light guide plate, the reflector, and the cushion layer are arranged in sequence from bottom to top. The light source is arranged in a strip shape on the inner edge of the lamp housing, and the light emitted by the light source is irradiated outward after passing through the reflector, the light guide with a plurality of protrusions, and the frosted diffusion plate, so that the ceiling lamp can emit light uniformly.

[0004] However, for the above-mentioned LED ceiling lamp with uniform light output, although the light guide plate, reflector plate, cushion layer and diffuser plate are fixed to the inner edge of the lamp housing from bottom to top by means of layer-by-layer edge abutment, there are still the following obvious defects during use: the light guide plate and the reflector plate are not clamped to the inside of the housing by means of a snap structure, and the layer-by-layer edge abutment method causes the upper light guide plate and reflector plate to slide from the diffuser plate and be damaged after the diffuser plate at the bottom of the lamp housing is removed when the lamp housing is disassembled from the ceiling because the surface of the diffuser plate is smooth.
