PROBLEM TO BE SOLVED: To provide a light wavelength conversion device for providing a stable light source having high quality, and to provide a lighting system having a light wavelength conversion device.SOLUTION: An light wavelength conversion device 5 includes a first substrate 51, a first wavelength conversion material 53, and a second substrate 52. The first substrate has at least one first segment 511. The first wavelength conversion material is included in the first segment in order to convert light in a first wavelength band into light in a second wavelength band. The light in the second wavelength band is reflected by the first segment. The second substrate is disposed at a lateral side of the first substrate and has at least one second segment 521. The light in the first wavelength band penetrates through the second segment.SELECTED DRAWING: Figure 3A 【課題】安定した高品質の光源を提供するための光波長変換器、光波長変換器を有する照明システムを提供する。【解決手段】光波長変換器５は、第一基板５１、第一波長変換物質５３、及び第二基板５２を含んでいる。第一基板は、少なくとも１つの第一セグメント５１１を有している。第一波長変換物質は、第一波長帯の光を第二波長帯の光に変換するために、第一セグメント内に含まれている。第二波長帯の光は第一セグメントにより反射される。第二基板は第一基板の横に配置され、少なくとも１つの第二セグメント５２１を有する。第一波長帯の光は第二セグメントを透過する。【選択図】図３Ａ
