โœฆ Synopsis


The relation between brightness temperature, true temperature and colour" temperature for a tungsten ribbon filament lamp has been calculated.The calculations were based upon the measurements of the emissivity of tungsten by d e V o s. Results are given in a nomogram (fig. ) and in the C.I.E. chromaticity diagram (fig. ). The luminances L of a black body and a tungsten ribbon have been calculated as a function of temperature T. It was found that
