Summary:In the first part of this paper, the authors present an analysis from photometrical (technical lighting) point of view of a DELFIN 03 type luminaire used in the modern street lighting. For this it started from determining by calculation (using a numerical calculation method - the method of equal plane angles) of the total luminous flux emitted by the street luminaire (polar photometric curves are required - polar luminous intensity distribution in different planes) and of the efficiency. The distribution of illuminances to different montage heights was then analyzed.In the second part of the paper, is presented a comparative study of the harmonic (distorted) regime produced by these luminaires equipped with high pressure sodium vapour tubular lamps type HST E40 socket, 250 W, for a network of street public lighting. In this regard was used an own conception computation program, developed in the Mathcad programming environment completed with an Excel subprogram.
