It is measured in lumen. What is lumen ? Lumen is the unit of luminous flux which is equal to the flux emitted per unit solid angle from a uniform source of one candle power. 1 lumen = 0.0016 watt (approx).
WebIf a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen (1 cd ·1 sr = 1 lm). Alternatively, an isotropic one-candela light-source emits a total luminous flux of exactly 4π lumens. Webthe entire wavelength spectrum gives the total blackbody emissive power E b: () 4 ()2 0 Eb T =∫EbλT dλ=σT W /m ∞ The Stefan-Boltzmann law gives the total radiation emitted by a blackbody at all wavelengths from 0 to infinity. But, we are often interested in the amount of radiation emitted over some wavelength band.
WebThe SI unit of luminous flux is the lumen (lm). One lumen is defined as the luminous flux of light produced by a light source that emits 1 cd of luminous intensity over a solid angle of 1 sr.
