ЧТО ОЗНАЧАЕТ СЛОВО LUMINOUS ENERGY
Световая энергия
В фотометрии световая энергия - это воспринимаемая энергия света. Это иногда называют количеством света. Световая энергия - это не то же самое, что лучистая энергия, соответствующая объективная физическая величина. Это связано с тем, что человеческий глаз может видеть свет только в видимом спектре и имеет различную чувствительность к свету разных длин волн в спектре. При адаптации к ярким условиям глаз наиболее чувствителен к свету на длине волны 555 нм. Свет с заданным количеством лучистой энергии будет иметь более светящуюся энергию, если длина волны составляет 555 нм, чем если длина волны больше или короче. Свет, длина волны которого находится за пределами видимого спектра, имеет световую энергию нуля, независимо от количества присутствующей лучистой энергии. Единица СИ светящейся энергии - это просвет второй, который неофициально известен как талбот в честь Уильяма Генриха Фокса Тальбота. В других системах единиц световая энергия может быть выражена в основных единицах энергии.
