Patent ID: 8847264

Claim:
A luminaire comprising: a semiconductor light source 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, wherein 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%, and a color gamut area ratio exceeds 100%.
