Abstract:
A projector and a wavelength-converting element are disclosed. The projector includes an illumination system, a light valve and a lens. The illumination system includes a light source providing an excitation beam, and a wavelength conversion device located at a transmission path of the excitation beam. The wavelength-converting element includes a substrate having a wavelength-converting area, an optical film disposed in the wavelength-converting area of the substrate, and a fluorescent film covering the optical film and converts the excitation beam into a converting beam. The converting beam and the excitation beam constitute an illumination beam. The fluorescent film contains phosphors, wherein the phosphors having a larger particle size are distributed among or above the phosphors having a smaller particle size. The light valve converts the illumination beam into an image beam. The image beam becomes a projection beam after passing through the lens.

Claim (Index 1):
A projector, comprising an illumination system, a light valve and a lens,\n the illumination system comprising a light source and a wavelength-converting element, the light source being configured to provide an excitation beam; the wavelength-converting element being located at a transmission path of the excitation beam, the wavelength-converting element comprising a substrate, an optical film and a fluorescent film,\n the substrate having a central area and a wavelength-converting area, wherein the wavelength-converting area surrounds at least part of the central area; \n the optical film being disposed in the wavelength-converting area of the substrate; \n the fluorescent film being disposed in the wavelength-converting area of the substrate and covering the optical film, and the fluorescent film being configured to convert the excitation beam into a converting beam, wherein the converting beam and the excitation beam constitute an illumination beam, the fluorescent film containing a plurality of phosphors having a plurality of particle sizes, the plurality of particle sizes comprising a first particle size and a second particle size, the first particle size being greater than the second particle size, wherein the plurality of phosphors having the first particle size are distributed among or above the plurality of phosphors having the second particle size; \n the light valve being located at a transmission path of the illumination beam and being configured to convert the illumination beam into an image beam; the lens being located at a transmission path of the image beam, wherein the image beam is for becoming a projection beam after passing through the lens.
