Abstract

The application discloses a light source device and a projection system. The light source device includes a light source for emitting excitation light; the first area of ​​the light splitting element is for receiving the excitation light emitted by the light source and transmitting or reflecting the excitation light; the wavelength conversion area of ​​the wavelength conversion device It is used to receive the excitation light transmitted or reflected by the first area of ​​the light splitting element to generate the received light; the excitation light reflection area of ​​the wavelength conversion device is used to reflect the excitation light incident on the excitation light reflection area of ​​the wavelength conversion device; when the light is split When the first area of ​​the element is used to transmit the excitation light emitted by the light source, the second area of ​​the light splitting element is used to reflect the excitation light reflected by the wavelength conversion device, and the first area and the second area are used to reflect the stimulated light; or, when When the first area of ​​the light splitting element is used to reflect the excitation light emitted by the light source, the second area of ​​the light splitting element is used to transmit the excitation light reflected by the wavelength conversion device, and the first area and the second area are used to transmit the received light.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a light source device and a projection system. Background technique [0002] Laser is a light source with high brightness, strong directionality, and monochromatic coherent light beam. Due to its many advantages, it has been gradually used as a light source in the field of projection display technology in recent years. In the field of display, as far as the realization of white light is concerned, using high-power blue LEDs or blue LDs to excite fluorescent substances and make them excited to obtain a combination of green, yellow, and red light to synthesize white light is a current white light solution. , this scheme has gradually attracted the attention of researchers in the industry because of its simplicity and low cost. [0003] In the current laser projection display products, most of the laser light source systems use laser-excited phosphors to emit light to re...
