Title (EN) WHITE LIGHT SOURCE
(FR) SOURCE DE LUMIÈRE BLANCHE
(JA) 白色光源
Abstract:
(EN) The white light source (1) of the embodiments has a color temperature of 2600 K to less than 3200 K. The ratio of the minimum light emission intensity to the maximum light emission intensity of the white light source of the embodiments in an emission spectrum wavelength region of 450 to 610 nm is 0.16 to less than 0.35.
(FR) L'invention concerne une source de lumière blanche (1) qui a une température de couleur allant de 2600 K à moins de 3200 K. Le rapport de l'intensité minimale d'émission lumineuse à l'intensité maximale d'émission lumineuse de la source de lumière blanche, dans une région de longueur d'onde du spectre d'émission située entre 450 et 610 nm, est de 0,16 à moins de 0,35.
(JA)  実施形態の白色光源1は、色温度が2600[K]以上3200[K]未満の白色光源である。実施形態の白色光源は、発光スペクトルの波長領域450~610[nm]における最大発光強度に対する最低発光強度の比率が、0.16以上0.35未満である。
