Abstract
An illumination device includes a light source including plural light emitting devices arranged in a pattern and that generate and guide light, the light emitting devices having tilted gain regions wherein guiding directions of the light are tilted with respect to a perpendicular of output surfaces of the light source, an optical axis conversion device that bends optical axes of the light output from the light source, and a light distribution control device that controls a light distribution angle of the light output from the optical axis conversion device, wherein the light emitting devices are super luminescent diodes, and the light output from the light distribution control device diverge.
