摘要
PROBLEM TO BE SOLVED: To obtain an illuminating fluorescent substance providing nearly the same white light as white light of a white light source for general illumination maintaining a well-balanced state of each component of the three primary colors of red, green and blue and a strong light emission with a high luminous intensity especially when a light source emitting a near ultraviolet light at 340-380 nm wavelength is used as an excitation light source. SOLUTION: The illuminating fluorescent substance excited by the near ultraviolet light at 340-380 nm wavelength and emitting the white light comprises a red fluorescent substance at 625-750 nm peak wavelength or an orange fluorescent substance at 575-675 nm peak wavelength, a green fluorescent substance at 500-600 nm peak wavelength and a blue fluorescent substance at 400-500 nm peak wavelength.
