Description

Technical Field

[0001] The utility model relates to the technical field of light guide plates for ceiling lamps, in particular to a fixing structure of light guide plates for outdoor ceiling lamps. Background Art

[0002] Ceiling lamps are increasingly widely used in furniture, office and other living scenes due to their advantages such as low consumption and high brightness. Ceiling lamps generally use light guide plates to guide light. The light guide plates are made of optical-grade acrylic / PC sheets, and then high-tech materials with extremely high reflectivity and non-light absorption are used to print light guide points on the bottom of the optical-grade acrylic sheets using laser engraving, V-shaped cross grid engraving, and UV screen printing technology.

[0003] When using a ceiling lamp, a light guide plate needs to be installed to make the light diffusion more uniform and the viewing experience more comfortable. However, the existing light guide plates are generally only suitable for a single light guide plate. When installing multiple continuous light guide plates, it is mostly necessary to install the keel first, and then install the light guide plate on the keel. After installation, the large light guide plate will have a strong sense of segmentation and a sense of splicing. At the same time, the keel is not easy to hide, which further reduces the viewing experience. In view of this, we propose a light guide plate fixing structure for an outdoor ceiling lamp.
