Title: LIGHT MIXING COLOR ILLUMINATION DEVICE
Abstract:
An object of the present invention is to provide a light mixing color illumination device capable of efficiently mixing, with a compact configuration, colors of light beams emitted from a multiple-wavelength light source having a plurality of light sources emitting different wavelengths. In order to achieve the above object, there is provided a light mixing color illumination device which mixes colors of light beams of a plurality of wavelengths, the device including: a multiple-wavelength light source having a plurality of light emitting surfaces; a light color mixing unit having a function of mixing colors of a plurality of light beams emitted from the multiple-wavelength light source; and a polarizing film which transmits light with polarization of a predetermined orientation emitted from the light color mixing unit and reflects light with other polarization, wherein the light color mixing unit is a rectangular columnar body formed of a transparent material and is configured to have a function of mixing colors of light beams emitted from the multiple-wavelength light source by internal reflection and a function of converting the orientation of polarization.
