Efficient light production in AC supplied LPS (low-pressure sodium) lamps is strongly dependent on plasma conditions within the complete half-cycle. Significant luminous efficacy gains are obtained with sinusoidal currents of hundreds of kilohertz or rectangular current form at lower frequencies. Measurements of light emission from a 18 W LPS at several operating conditions, reported in this paper, can be useful to establish a compromise between supply frequency and current waveform shape for electronic ballast design.
