Description
S2(λ)=SSR(λ)+SAR(λ) ・・・(式9)
これに対して、本実施形態においては赤色光とアンバー色光の比率が上記比率(例えば、赤色:アンバー色=100:2.7~4.0)となるように第1光源20A及び第2光源20Bを同時に点灯した場合のスペクトルをS1(λ)とする。
上記式8、式9、式10用いて、比較例と本実施形態それぞれでP型色覚者が感じる明るさを算出すると、比較例でP型色覚者が感じる明るさは1.000であるのに対して、本実施形態でP型色覚者が感じる明るさは1.108となり、比較例に対して、本実施形態でP型色覚者が感じる明るさは10.8%向上する。
<変形例1>
上記実施形態では、第1光源20A、第2光源20BとしてLEDを用いた例について説明したが、これに限らない。例えば、第1光源20Aとして赤色光を発光する第1有機EL(有機ELパネル。以下、第1有機EL20Aとも呼ぶ)、第2光源20Bとしてアンバー色光を発光する第2有機EL(有機ELパネル。以下、第2有機EL20Bとも呼ぶ)を用いてもよい。
<変形例2>
また、例えば、第1光源20Aとして赤色光を発光する第1フィルム光源(以下、第1フィルム光源20Aとも呼ぶ)、第2光源20Bとしてアンバー色光を発光する第2フィルム光源(以下、第2フィルム光源)を用いてもよい。
<変形例3>
図10(a)は光学部品30としてリフレクタ(以下、リフレクタ30とも呼ぶ)を用いた車両用灯具10C(変形例)の上面図である。
<変形例4>
図10(b)は光学部品30として2つのリフレクタ(以下、第1リフレクタ30A、第2リフレクタ30Bとも呼ぶ)を用いた車両用灯具10D(変形例)の上面図である。
