Abstract: A lens array panel includes a substrate and plural microlens structures periodically arranged on a side of the substrate, and the substrate and the microlens structure are integrally formed. The substrate and the microlens structure has a contact surface which is either a convex surface or a concave surface, so that the lens array panel have either a light scattering function or a light condensing function. The lens array panel formed by the substrate with a non-planar (convex or concave) surface has a light scattering or condensing function to achieve effects of adjusting the angle and illumination of the light and minimizing the use of lighting equipments for the same region.

Abstract: A flat panel lamp according to the invention comprises a light guide structure, at least a reflector member, at least a diffusion member and a light source module. The light guide structure has a bottom surface, an illuminating surface corresponding to the bottom surface, and a side surface located between the bottom surface and the illuminating surface. The reflector member is located at the bottom surface of the light guide structure. The diffusion member is located between the light guide structure and the reflector member. The light source module is located at the side surface of the light guide structure. The problem of non-uniform brightness can be resolved by the diffusion member, and the luminance intensity of the whole flat panel lamp can also increased.
