Document Type and Number:
WIPO Patent Application WO/2012/138020
Kind Code:
A1
Abstract:
Disclosed are a light source apparatus and a method for manufacturing the same. The light source apparatus is capable of enhancing color reproducibility by a wavelength conversion material configured to convert a wavelength of excitement light, and including an inorganic or organic pigment for absorbing or reflecting/transmitting a specific wavelength band of the wavelength-converted light. The light source apparatus comprises a light source configured to generate excitation light, an optical system configured to focus the excitation light, and a color wheel configured to generate a plurality of color lights based on the focused excitation light, wherein the color wheel comprises a fluorescent layer configured to convert a wavelength of the excitement light, containing an inorganic or organic pigment for absorbing or transmitting (reflecting) a specific wavelength band of the wavelength-converted light.
