摘要
The return on investment from adopting centralized energy saving systems for street lighting can be compromised by voltage drop in long distribution lines. Large, centralized systems can reduce the output voltage sufficiently to dim distant high intensity discharge lamps. In this paper, the authors explore alternative dimming techniques and study the behavior of a 400W HPS lamp when supplied by trapezoidal or rectangular voltages rather than the conventional sinusoidal supply. The efficiency and effectiveness of these alternatives are assessed by means of laboratory experiments.
