Light production metrics of radiation sources
arXiv:1311.3504 · doi:10.1088/0143-0807/35/4/045006
Abstract
Light production by a radiation source is evaluated and reviewed as an important concept of physics from the Black-Body point of view. The mechanical equivalent of the lumen, the unit of perceived light, is explained and evaluated using radiation physics arguments. The existence of an upper limit of luminous efficacy is illustrated for various sources and implications are highlighted.
