Abstract

The invention discloses a wavelength conversion device and a laser fluorescent conversion type light source. The wavelength conversion device comprises a packaging assembly and a fluorescent assemblywhich can convert incident light into emergent light. The packaging assembly is in a cuboid shape and is provided with four side faces and on sealed end face, wherein the other end, opposite to the sealed end face, of the packaging assembly is an opening and serves as a light emergence end. One side face or the two side faces of the packaging assembly is / are used as a light incidence end / light incidence ends, and an incident light window is formed. An optical film allowing specific light beams to pass through is arranged on the surface of the incident light window. In addition, the inner surfaces of other side faces, except the side face serving as the light incidence end, and the sealed end face are reflecting surfaces. The fluorescent assembly is arranged in the packaging assembly, and one end of the fluorescent assembly is connected to the sealed end face. A step structure is formed on the surface, opposite to the incident light window by spacing an air clearance, of the fluorescentassembly, the thickness is reduced in a step manner from the sealed end face to the light emergence end, and lambert reflecting layers or mirror face reflecting layers are arranged on the side wallsof at least part of steps of the step structure.

Description

technical field [0001] The present invention relates to a wavelength conversion device and a laser fluorescence conversion light source using the wavelength conversion device. Background technique [0002] In recent years, laser light sources have become an important development direction of projection light sources.
