摘要

In this work, two types of commercially available compact fluorescent lamps (CFL) were investigated for intensity variation due to mechanical vibrations in the range of 0 to 30 Hz. In general, subjecting the lamps to 24-hour vibration affects the total intensity. Percentage variations of peak intensities after vibrations is in the range of + 10 to + 35 percent in case of CFL (Nuvue), whereas for the CFL (Ecosmart), it is in the range of-10 to + 10 percent. Continuous vibration measurements at various vibrational frequencies (intensity measurements at each frequency after subjecting the unit to mechanical vibrations for 10 minutes) show that the CFL luminaires, exhibits a peak in intensity at a vibrational frequency around 25 Hz for a wavelength of 546.78 nm (wavelength of maximum human sensitivity). Intensity variation effects due to vibration are attributed to the dropping off loose phosphor coatings in the inside wall of the glass enclosures. This hypothesis needs to be investigated further.
