57 Abstract AB [EN] Since the average life of long-life incandescent lamps (Sig lamps) is approximately 6000 hours, the use of general-purpose incandescent lamps with more than double the rated power and the use of pulse operation to extend their life to more than 100,000 hours is more expedient. Pulse operation, which is barely detectable by eye, reduces the r.m.s. incandescent lamp current by means of phases between the pulse phases in which no current flows. In consequence, far better data are obtained when operating Sig lamps with respect to the light intensity, the colour temperature and, especially, the power saving. Such pulse operation is carried out, for example, using the 50 Hz half-cycles of the AC mains, whose phases in which no current flows can still be optimised by means of a phase gating angle of approximately 90 DEG . <IMAGE>
