Abstract

In order to be able to evaluate the luminous characteristics of light sources it is necessary to know, amongst other things, the radiated luminous flux in the various directions within the space around the source, i.e. the distribution of the luminous intensity, termed the light distribution of the source. It must also be possible to express this numerically or graphically.
