<P>PROBLEM TO BE SOLVED: To provide a lighting device and a light source adjustment device eliminating the unevenness of brightness and color temperature by appropriately alleviating the fluctuation of luminance of a plurality of LEDs for R, G, and B each constituting a light source of a strobe device for a camera or the like, and enabled to appropriately emit illumination light of a prescribed color temperature. <P>SOLUTION: At the time of light source adjustment, a system controller 10 makes each LED nR, nG, and nB (n=1 to M) constituting the light source emit light in turn, and adjust resistance values of variable resistors VRnR, VRnG, and VRnB so that brightness detected by a light receiving sensor S be a prescribed value at that time. Subsequently, all the LEDs are made to emit light, at which time, resistance values of the variable resistors VRR, VRG, VRB are adjusted so that the color temperature detected by a color temperature sensor 18 be a prescribed color temperature. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
