> This operator's description has not been translated yet. The original text follows as it is.
減能グレアの光幕輝度 L_v [cd/m²] (配列可)。E_glare = 目の位置での光源の照度 [lx]、θ = 光源と視線の角 [度]。
`model="stiles_holladay"`: L_v = 10 E / θ²(θ は 1°〜30° 程度で使われる経験式)。
`model="cie"`: CIE 146:2002 の一般式 L_v/E = 10/θ³ + (5/θ² + 0.1 p/θ)(1 + (age/62.5)⁴) + 0.0025 p
(p = 目の色素の係数、既定 0.5)。θ ≤ 0 は拒否(光源そのものは光幕でなく像)。
