<P>PROBLEM TO BE SOLVED: To provide a light emitting apparatus, capable of suppressing manufacturing cost while maintaining a good light adjustment function and good light emitting efficiency, by combining LED chips with wavelength conversion members. <P>SOLUTION: The light emitting apparatus comprises: a wiring board; a plurality of LED chips disposed on the wiring board and grouped into a plurality of LED groups, for emitting light in a prescribed wavelength range in a wavelength region from a visible light region to a near ultraviolet region; wavelength conversion members disposed in positions opposite to an LED chip mounting surface of the wiring board, and, corresponding to the plurality of LED chips, divided into a plurality of wavelength conversion regions that are grouped into a plurality of wavelength conversion groups corresponding to the LED groups, for radiating light by converting each light wavelength emitted from each corresponding LED chip, with different wavelength conversion characteristics for each wavelength conversion group; and drive means for supplying currents to the LED chips independently on an LED group basis. <P>COPYRIGHT: (C)2012,JPO&INPIT |
