Patent ID: 8393741

Claim:
A light source system comprising: a luminescent wheel in which a luminescent material layer is disposed circumferentially; a driving unit for rotating the luminescent wheel; a light source for shining excitation light onto the luminescent material layer; a light shining control unit for controlling an illumination starting timing of the light source; a light shining time integrating unit for integrating individual excitation light shining times to a plurality of predetermined divided areas of the luminescent wheel by the light source; an integrated light shining time storage unit for storing the individual light shining times to the predetermined divided areas integrated by the light shining time integrating unit; and a light shining range control unit for equalizing times over which excitation light is shone onto the plurality of predetermined divided areas of the luminescent wheel based on the individual excitation light shining times to the predetermined divided areas which are stored in the integrated light shining time storage unit.
