A new concept which should facilitate the calculation of illumination from long linear light sources is proposed and a general theory of the infinite linear source is given.
The errors incurred when applying infinite source relations to finite layouts are assessed for three types of sources.
How the results of this analysis can be applied to practical design tasks is shown in a few examples of fluorescent lamp layouts.
