When the light source radiation is uniform, the light intensity is I=F/Ω, Ω is the solid Angle, the unit is sphericity (sr), F is the luminous flux, the unit is lumen, for the point light source by I=F/4π. Brightness is the brightness of the luminous surface, refers to the ...
1. (Units) the quotient of the luminous flux of a radiation and its corresponding radiant flux. Symbol: K 2. (Units) the quotient of the luminous flux emitted by a source of radiation and the power it consumes. It is measured in lumens per watt. Symbol: ηv or Φv Collins...
Luminous intensity [cd] (of a source, in a given direction): Quotient of the luminous flux [lm] leaving the source and propagated in the element of solid angle [sr] containing the given direction, by the element of solid angle [sr]. In other words, it is the luminous flux [lm] leav...
