<p>PROBLEM TO BE SOLVED: To provide an illumination device for color vision deficient persons capable of corresponding to an individual difference or an ambient environment change.SOLUTION: An illumination device 1 comprises: a light source including a plurality of kinds of LED elements 5 having different emission wavelength ranges; a spectral colorimeter 8 for measuring a wavelength intensity distribution of external light; a memory 10 for storing a plurality of basic spectrum patterns of the light source 4; a changeover switch 7 for receiving a result that a user selects one of the plurality of basic spectrum patterns; a CPU 11 which executes correction processing for correcting the basic spectrum pattern selected by the user on the basis of the wavelength intensity distribution of the external light measured by the spectral colorimeter 8; and a lighting control circuit 12 capable of individually controlling emission intensities of the plurality of kinds of LED elements 5 on the basis of the corrected basic spectrum pattern.</p> |
