Illumination light color correction method, light source module employing the color correction method, and illumination device using the light source module

摘要

Provided is a lighting device capable of correcting loss of color balance of illumination light that tends to occur among a plurality of light source modules and providing uniform illumination light of the same color. A lighting device 1 including a plurality of light source modules 2A to 2D corrects the color of light emitted from each light source module to emit uniform illumination light of the same color. Each of the light source modules 2A to 2D includes: first light source modules 2B to 2D that each have a point light source 3 emitting light of a color having a plurality of wavelength components, a casing 4 accommodating therein the point light source, provided with an opening, and having an interior with a reflection surface, and an optical reflective member covering the opening of the casing and emitting uniform surface illumination light; and a second light source module 2A that is the first light source module further equipped with a color correcting member 7 adjusting a spectrum of the light emitted from the corresponding point light source.
