Phosphor composition for a luminaire |
摘要 |
A luminaire includes a semiconductor light source (5) having a light emission peak in a range of wavelength smaller than 480 nm and a phosphor excited by light radiated from the semiconductor light source to radiate light having wavelength equal to or larger than 480 nm. A spectrum of radiated light obtained by combining the light radiated from the semiconductor light source and the light radiated from the phosphor has a light emission peak in a range of wavelength equal to or larger than 610 nm and smaller than 650 nm. A ratio of radiation energy in a range of wavelength equal to or larger than 650 nm and equal to or smaller than 780 nm to radiation energy in a range of wavelength equal to or larger than 600 nm and smaller than 650 nm is equal to or lower than 35%. A color gamut area ratio exceeds 100%. |
