Koshel, Field ...Radiance Le = dle/dsxcos8 (watts per steradian.m2) (Eq. 1-14) Where Ie: radiant intensity s : area 8 : angle between viewing direction and small area surface. Luminance L = dl/dsxcos8 (candelas/m2) ~ (Eq. 1-15) Where I: luminous intensity (candelas) RADIANT SOURCE (LIGHT SOURCE), , L . NORMAL (NORMAL RADIANCELUMINANCE) VIEWING DIRECTIONFormula of Radian. Firstly, One radian = 180/PI degrees and one degree = PI/180 radians. Therefore, for converting a specific number of degrees in radians, multiply the number of degrees by PI/180 (for example, 90 degrees = 90 x PI/180 radians = PI/2). To convert a specific number of radians into degrees, multiply the number of radians by 180/PI.Radiant intensity [Luminous intensity] watts per steradian [candelas] W/sr [cd] watts per steradia' square meter W/sr"m2 Radiance [Luminance] [candelas per square meter] [cd/m2] Table 1-2: Comparisons of radiant units with photometric units (shown in brackets [ ])The luminous flux of the LED is measured in units of Lumens so we choose that unit for this simulation. Illuminance is therefore measured in terms of lm/m2, or Lux. Luminous intensity ("brightness") is measured in lumens/steradian or Candela (Cd). Luminance is measured in lm/m2/sr, or Cd/m2, which is sometimes referred to as a nit.Answer. Steradians are a measure of the angular 'area' subtended by a two dimensional surface about the origin in three dimensional space, just as a radian is a measure of the angle subtended by a one dimensional line about the origin in two dimensional (plane) space. Steradians are equivalently referred to as 'square radians.'.The SI unit of solid angle is the steradian (sr). The solid angle of a complete sphere is 4π sr.
