Abstract

In physical photometers the energy of the light rays falling upon the surface of a light-receptor is transformed into another form of energy. Since “energy”, or better “energy per second” i.e. “power”, in terms of lighting technology refers to “luminous flux”, the flux falling on the light-receptor, i.e. the illumination is measured.
