Optical wavelength converter and its applicable light source system

Abstract

The invention relates to an light wavelength converter which can be applied to convert light of a first wavelength. The converter comprises a first substrate, a first wavelength conversion material and a second substrate, wherein the first substrate includes a first section. The first wavelength conversion material is arranged in the first section, and used to convert the light of the first wavelength into light of a second wavelength, and the light of the second wavelength is reflected by the first section. The second substrate is arranged adjacent to the first substrate, and includes a second section, and the second section is arranged interlaced with the first section so that the light of the first wavelength can pass. Thus, laser spots can uniformly and stably penetrate the light wavelength converter, the light wavelength converter can be effectively and accurately controlled, ratio errors of the spots can be avoided, the intensity and chroma of emergent light are stable, and the quality of light is improved.

Description

technical field [0001] The present invention relates to an optical wavelength converter, in particular to an optical wavelength converter providing a stable and high-quality light source and an applicable light source system. Background technique [0002] Optical wavelength converter is an optical transduction element, which is mainly used to convert more than one wavelength of light to generate specific visible light wavelength as a light source. It is usually used in special lighting, such as spotlights, headlights, display light sources or projectors. Like wait. [0003] Generally speaking, the traditional optical wavelength converter is based on the fluorescent pink wheel, which aims to cooperate with the laser light source and convert the laser light into colored light with different wavelengths. projection. Under high power operation, the light wavelength conversion efficiency of the fluorescent pink wheel can greatly improve the photoelectric conversion and lumen ou...

Problems solved by technology

[0008] The main purpose of the present invention is to provide an optical wavelength converter and its applicable light source system to solve the problem that traditional optical wavelength converters cannot accurately control the swing amount at high speeds, and blue light spots are prone to occur when the substrate radius is large. Ratio error and rotation balance problems lead to disadvantages such as poor light quality caused by unstable blue light output intensity and chromaticity
