Abstract
A light panel is disclosed. The light panel comprises a circuit assembly, a plurality of light sources, a light reflective structure, and a diffuser layer. The light reflective structure has a plurality of concaves, which are continuously connected to form a plurality of ridges. Each of the concaves has an opening formed on the bottom surface thereof, and each of the light sources is disposed corresponding to each of the openings of the concaves. The diffuser layer is supported by the ridges of the light reflective structure. In some aspects of the present invention, the diffuser layer may have a sloping inner surface or is coated with patterned diffuser coatings on the top surface. Each light source can be added with a lens.
