ILLUMINATION APPARATUS AND PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240255838 titled 'ILLUMINATION APPARATUS AND PROJECTOR
The abstract describes an illumination apparatus that includes a light source device emitting light containing three different colors and a polarization converter that converts the light into polarized light. The converter separates the light into two polarized lights and uses a wave plate to convert one of them. The majority of one color light output is polarized, and the wavelength for optimal polarization rotation efficiency falls between the peak wavelengths of the other two colors.

Original Abstract Submitted
an illumination apparatus includes a light source device configured to a light containing a first color light, a second color light, and a third color, and a polarization converter converting a first polarized light of the light emitted from the light source device into a second polarized light, wherein the polarization converter has a polarization separation part separating the light emitted from the light source device into the first polarized light and the second polarized light, and a wave plate converting the first polarized light into the second polarized light, 80% or more of the first color light output from the light source device is the second polarized light, and a wavelength at which polarization rotation efficiency of the wave plate is the highest is longer than a peak wavelength of the second color light and shorter than a peak wavelength of the third color light.
