Problems solved by technology

The actual situation is as figure 1 As shown, the light entrance 1 of the optomechanical system is usually a rectangular hole, but the incident light spot 2 is circular or approximately circular, so the shape and size of the incident light spot 2 and the light entrance 1 do not match, and part of the light will be irradiated to the The outside of the light entrance 1, causing a technical problem with the loss of brightness of some light sources

Embodiment Construction

[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] With the development of optical projection technology, laser projection technology has been more and more widely used. Most of the laser projectors use blue lasers, and then use blue lasers to excite phosphors of other colors to obtain stimulated light of other colors to obtain colored light sources.

[0037] Laser fluorescent light source refers to a light source device that uses blue laser to excite phosphor powder to generate fluorescence. In order to ensure sufficient brightness, two blue laser light sources a...

Abstract

The invention provides a light source device and an optical system, and relates to the technical field of optics. The light source device comprises at least two light source assemblies, an exciting light path assembly, an excited light path assembly and a wavelength conversion assembly; at least two beams of exciting light emitted by the at least two light source assemblies respectively pass through different paths in the exciting light path assembly and reach the wavelength conversion assembly to form at least two non-coincident exciting light spots, and the at least two non-coincident exciting light spots excite the wavelength conversion assembly to generate at least two beams of excited light; and the at least two beams of excited light respectively pass through different paths in the excited light path assembly and are combined to form output light. The light source device relieves the technical problem of light source brightness loss in the prior art.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a light source device and an optical system. Background technique [0002] With the development of optical projection technology, laser projection technology has been more and more widely used. Most of the laser projectors use blue lasers, and then use blue lasers to excite phosphors of other colors to obtain stimulated light of other colors to obtain colored light sources. [0003] Laser fluorescent light source refers to a light source device that uses blue laser to excite phosphor powder to generate fluorescence. In order to ensure sufficient brightness, two blue laser light sources are usually arranged inside the light source device. In this light source device, the excitation light emitted by two blue laser light sources is synthesized into one beam through the light-combining element first, and then incident on the phosphor through the light-shaping element, the beam spli...
