16 13 June 2002 Page: 16 FS M PLANON ® dimming technology: Principles PLANON ® generates light by using very short pulses The voltage, which generates these short discharge pulses is shown to the right time To ensure a maximum of light stability, it is necessary to have a certain voltage (or energy) per pulse

17 13 June 2002 Page: 17 FS M PLANON ® dimming technology: Two different principles 100% Luminance ULUL 50% ULUL ULUL 20% ULUL PWM-Dimming: PWM m eans pulse width modulated, this possibility of dimming uses the inertia of the human eye. The signal is chopped into smaller portions at a rate not visible to the eye. The dimming ratio is proportional to the green coloured area. The PWM-dimming yields much better dimming rates than the analogue dimming. Analogue Dimming: The height of the signal (e.g. voltage) is adjusted to have a lower light output. The PLANON ® dimming range for this technology is 100…~50%.
