Problems solved by technology

[0003] However, the current lighting system of the projector must use a lot of optical elements to guide the transmission of the lighting beam. In addition to complicating the optical path of the beam and reducing the optical efficiency of the projector, it will further lead to high cost and large volume. and noise problems

Abstract

The invention discloses a projector, a lighting system and a wavelength converter thereof. The wavelength converter includes a substrate, a wavelength converting portion, and a wavelength maintainingportion. The wavelength converting portion surrounds the rotation axis of the substrate and is configured to receive the first light beam to convert the first portion of the first light beam into a second light beam. The wavelength maintaining portion surrounds the rotation axis of the substrate and is configured to receive a first light beam to guide a second portion of the first light beam, theratio of the first portion of the first light beam to the first light beam being greater than the ratio of the second portion of the first light beam to the first light beam. The lighting system and the wavelength converter of the present invention are arranged in a projector so as to reduce the number of optical elements, thereby reducing the cost and reducing the volume of the projector.

Description

technical field [0001] The invention relates to a wavelength conversion device, in particular to a wavelength conversion device used in a projector and an illumination system. Background technique [0002] A digital light processing (DLP) projection device includes an illumination system, a light valve and a projection lens, wherein the illumination system is used to provide an illumination beam, the light valve is used to convert the illumination beam into an image beam, and the projection lens is used to convert The image light beam is projected on the screen to form an image frame on the screen. With the development of lighting technology, lighting systems of projector devices gradually adopt light sources with energy-saving advantages such as light-emitting diode light sources and laser light sources. [0003] However, the current lighting system of the projector must use a lot of optical elements to guide the transmission of the lighting beam. In addition to complicati...
