발광 에너지

발광 에너지(發光energy, luminous energy)는 인간의 눈이 받아들이는 빛의 에너지를 말한다. 인간의 눈이 얼마나 민감하게 받아들이는지를 측정하는 것이기 때문에 복사 에너지와는 다르다. 다시 말해, 가시광선의 에너지만을 측정하며, 인간의 눈이 가장 민감하게 받아들이는 555나노미터 파장의 빛을 가장 에너지가 강한 것으로 취급한다.

SI 단위는 루멘 초이며, 이 단위는 윌리엄 폭스 탤벗의 이름을 따서 탤벗(talbot)이라고도 부른다.

(광원의) 발광효율(luminous efficacy of a source) η 루멘 매 와트 lm/W cd⋅kg-1⋅m-1⋅s4 전등효율이라고도 하며, 어떤 광원에서 1W의 소비전력에 따라 발생하는 광선속 양의 비를 나타낸다. 이론적 최대치는 비시감도에 따라 파장별로 상이하고 파장 555nm에서 683 lm/W의 최대값을 가지나 실제로는 이보다 낮다.
