ILLUMINATION OPTICAL SYSTEM USING SEMICONDUCTOR LASER DEVICE AS LIGHT SOURCE AND PROJECTOR UTILIZING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide an illumination optical system using semiconductor laser devices as a light source and a projector utilizing the same. PSOLUTION: The illumination optical system includes: a laser array base plate 68 where LEDs (light emitting diodes) 62 emitting light having the wavelength of red (R), LEDs 64 emitting light having the wavelength of green (G), and LEDs 66 emitting light having the wavelength of blue (B) are arranged in a two-dimensional array; a fly-eye lens 120 arranged in front of the base plate 68; and a condenser lens 122 arranged in front of the lens 120.
