Abstract
A projector using glass phosphor as a color mixing element includes: a laser light source capable of producing light; an optical system, the color mixing member, a reflection element and an imaging system disposed on a light transmission path. The optical system includes a color wheel, the light will be converted into light beams of different colors when passing through the color wheel. The color mixing element is located between the laser light source and the optical system and made of glass phosphor, and a glass transition temperature of the glass phosphor being higher than 500° C. The imaging system serves to convert the light beams into an image. The use of the heat-resistant glass phosphor as the color mixing element enables the projector to have a wide color gamut and an adjustable color gamut.
