IlluminanceMeasure | rangeSubclass | SubtractionFn | A FunctionQuantity is a Function that maps from one or more instances of ConstantQuantity to another instance of ConstantQuantity. For example, the velocity of a particle would be represented by a FunctionQuantity mapping values of time (which are ConstantQuantities) to values of distance (also ConstantQuantities). Note that all instances of FunctionQuantity are Functions with a fixed arity. Note too that all elements of the range of a FunctionQuantity have the same physical dimension as the FunctionQuantity itself | (<=> | domainSubclass | FunctionQuantity | |

Lux | rangeSubclass | MeasureFn | SI IlluminanceMeasure. Symbol: lx. It is the amount of illumination provided when one Lumen is evenly distributed over an area of 1 square Meter. This is also equivalent to the illumination that would exist on a surface all points of which are one Meter from a point source of one Candela. Lux = lm/m^2 = m^(-2)*cd | (=> | domainSubclass | SystemeInternationalUnit |
