【 摘 要 】

This paper aims to determine the luminous flux of several types of power sources used for the artificial lighting inside. The luminous flux was determined using a photometer integrator (lumenmeter Ulbricht) and a luxmeter from the laboratory of Electrical and Lighting University "Eftimie Murgu" Resita. Based on a reference source, the constant of the integrator photometer k was determined. The paper presents the measuring results of the luminous flux on several lighting sources: with incandescent, fluorescent, and LED. It has been found that the amount of luminous flux in the nominal data written in the box of lighting sources, does not correspond to the actual measured value. Using the photometric sphere, the actual light output from various sources were it is not known, can be determined.
