Abstract

An illuminating device which is provided with a plurality of light source units is provided. Each of the plurality of light source units includes a light emitting unit having a light emitting device, a first optical system that adjusts an optical path of light emitted from the light emitting unit, an electrode that supplies power to the light emitting unit, and a connecting element that connects the light emitting unit to the electrode and is disposed so as to block a part of the optical path of light from the light emitting unit thus to create an unilluminated area. In this structure, the plurality of light source units are arranged such that unilluminated areas of the plurality of light source units are substantially uniformly distributed over an entirety of an area illuminated by all the plurality of light source units.
