Internal Traceability between Luminous Flux and Illuminance Standards

  title={Internal Traceability between Luminous Flux and Illuminance Standards},
  author={P. Fiorentin and Alessandro Scroccaro},
  journal={2008 IEEE Instrumentation and Measurement Technology Conference},
Two methods for the measurement of the luminous flux are presented: the first is based on an integrating sphere and a luminous flux standard lamp, the second utilizes an accurate goniometer and an accurate illuminance meter. A comparison between the two methods is carried on for two different light sources: an LED and a halogen source, presenting different luminous fluxes. The measuring procedure and an evaluation of the measurement uncertainties are described for both the methods. The… CONTINUE READING
