光波长转换器及其适用之光源系统;OPTICAL WAVELENGTH CONVERTER AND ILLUMINATION SYSTEM USING SAME

摘要

本案系关于一种光波长转换器，适用于转换第一波段光并包括第一基板、第一波长转换材料及第二基板，且第一基板具有第一区段。第一波长转换材料设置于第一区段，用以将第一波段光转换为第二波段光，且该第一区段系反射该第二波段光。第二基板邻设于第一基板且具有第二区段，其中第二区段系与第一区段交错设置，俾使第一波段光穿透。藉此，雷射光斑可均匀且稳定地穿透本案之光波长转换器，不仅可有效且精准地控制光波长转换器，更可避免光斑之配比误差，进而使出光强度及色度稳定，并达到提升出光品质之功效。;An optical wavelength converter for converting a first waveband light includes a first substrate, a first wavelength-converting material and a second substrate. The first substrate has a first segment. The first wavelength-converting material is disposed on the first segment for transforming the first waveband light into a second waveband light. The second waveband light is reflected by the first segment. The second substrate disposed adjacent to the first substrate has a second segment. The second segment is staggered with the first segment, such that the first waveband light is transmitted through the second segment. Under this circumstance, the laser speckle can be uniformly transmitted through the optical wavelength converter of the present invention. Not only the optical wavelength converter is effectively and precisely controlled, but also the deviation of the ratio of the laser speckle is avoided, so that the intensity and the chroma are stable. Meanwhile, the quality of the output light is enhanced.
