STUDYING THE CHARACTERISTICS OF DISCHARGE LAMPS FOR OPERATION IN NAVIGATION LIGHTHOUSES SUPPLIED BY PHOTOVOLTAIC SYSTEMS
S. Platikanov, P. Tsankov
Abstract
This paper presents the results of the research done on the start-up process of discharge lamp ignition up to the transition into a steady-state regime of operation. The paper studies the change in the basic electrical characteristics: current, voltage, power, power factor, as well as the change in the luminous flux. Different operation circuits of the lamps are discussed: from the mains supply with and without a compensating capacitor. Conclusions have been drawn about this initial period in the ignition of discharge lamps and their application and possibilities of use in navigation lighthouses supplied by photovoltaic systems.
Keywords: discharge lamp, navigation lighthouse, photovoltaic system, electrical characteristics, luminous flux, luminous efficacy.
