Abstract
An illumination apparatus includes a frame, an optical base plate, a light source and an optical film. The optical base plate is disposed in the frame and has a first protrusion portion at the center of the optical base plate. The first protrusion portion has at least a reflective surface and a top surface, which are connected with each other. The light source is disposed in the frame and located adjacent to the periphery of the optical base plate. The light source is disposed corresponding to the reflective surface and has a plurality of light-emitting elements. Each light-emitting element has an optical axis direction, and the optical axis directions extend toward the first protrusion portion. The optical film is disposed at the frame, and the first protrusion portion of the optical base plate protrudes toward the optical film.
