Zusammenfassung:PROBLEM TO BE SOLVED: To provide favorable color rendering of white light so as to fit in with "daylight white" effect required in various applied places.SOLUTION: A light emitting module of the present embodiment includes: a (circuit) board; at least one ultraviolet light emitting medium; at least one blue light emitting medium; and a wavelength conversion layer. The ultraviolet light emitting medium and the blue light emitting medium are installed on the board and a wavelength range of light beams of the ultraviolet light emitting medium is 380 nm-420 nm and a wavelength range of light beams of the blue light emitting medium is 440 nm-470 nm. The wavelength conversion layer includes a first wavelength conversion material and a second wavelength conversion material; and is used for receiving light beams emitted by the ultraviolet light emitting medium and the blue light emitting medium; and excites light beams of the ultraviolet light emitting medium to generate visible light; and converts light beams of the blue light emitting medium to white light; and mixes the light to obtain daylight white total output spectrum.SELECTED DRAWING: Figure 1 【課題】本発明は、様々な応用箇所で求められる「昼白」効果に符合するように、好ましい白色光の演色性を提供することにある。【解決手段】本発明は、(回路)基板と、少なくとも一つの紫外光放射体と、少なくとも一つの青色光放射体と、波長変換層とを包括している。前記紫外光放射体及び前記青色光放射体は前記基板上に設置し、前記紫外光放射体の光線の波長範囲が380nm〜420nmであり、前記青色光放射体の光線の波長範囲が440nm〜470nmである。また、前記波長変換層は、第一波長変換材料及び第二波長変換材料を包含し、前記紫外光放射体及び前記青色光放射体が放射する光線を受けるために用い、前記紫外光放射体の光線を励起して可視光を発生し、前記青色光放射体の光線を白色光に変換し、これ等光を混合することで昼白な総出力スペクトルを得ている。【選択図】図1
