Impact of Current Crest Factor at High and Low Frequency Operation on Fluorescent Lamp Electrodes

This paper presents an analysis of the benefit-cost ratio of turning off or not a fluorescent lamp in small time intervals, based on the relation between energy consumption and lamp lifetime depreciation. Thus, this paper analyzes compact fluorescent lamp ignition characteristics considering factors such as: electrical performance, lifetime depreciation, power consumption and the relationship between electrical energy cost and lamp lifetime reduction by switching it on/off. The experimental results show the equivalence between the lamp lifetime depreciation and electrical energy cost to keep it on when it is activated for a certain cycled time period.

“…Both phenomena result in the weakening of the filaments and their final fracture before their rated life. [3][4][5] During steady-state operation, due to the heat emanating from the discharge between the two electrodes, the filament temperature is maintained at high values. Few types of ballast continue to supply the preheating voltage during operation to keep the temperature of the electrode high.…”

This paper presents the results of an experimental investigation of the life of T5 fluorescent tubes and compact fluorescent lamps with non-integrated ballasts. The lamps were operated on five different cycles with either instant start ballasts or electrode preheating ballasts. The influence of the operation time on the lamp life of every start was examined. During both the start and the operation of the lamps, measurements of particular electrical characteristics were carried out. The investigation focused on the effect of the starting and operating characteristics on the lamp lifetime. Lamps operating with ballasts providing preheat at the start up, showed a systematic change in certain electrical characteristics that can help to predict their failure.
