Abstract
A light emitting apparatus includes a plurality of full-color LED units. Constant current values of the constant current elements are set such that the plurality of full-color LED units come closer to a same chromaticity as compared with a case in which all the constant current elements of all the full-color LED units have a same constant current value. As a result, in at least one of the plurality of full-color LED units, at least one of the plurality of constant current elements is set to a constant current value different from that of the other constant current elements.
