摘要:
Methods are proposed for determining the flux of a fluorescent lamp from illumination readings at a comparatively close distance without the aid of an integrator.A full mathematical analysis based on a previous paper of the authors is given and experimental checks are described.Of the methods described, one, the “three illumination-readings” method might be useful for type-tests; while another, the “single illumination-reading” method is applicable to routine tests on a particular lamp-type.
