9. PLANON® operating principle
PLANON® generates light using pulsed dielectric barrier discharge
A suitable voltage is applied to the electrode system of the lamp from the outside. It excites xenon atoms in the gas chamber and enables the formation of excited Xe2* molecules
UV-radiation is transformed into visible light by phosphors

11. PLANON® microdischarges
Small protrusions affixed to the cathode lines function as starting points of microdischarges
The discharge channels widen to roughly triangular shapes ending on the opposing electrode lines
The high homogeneity featured by PLANON® is achieved by placing these triangular discharge filaments throughout the whole lamp surface

16. 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
To ensure a maximum of light stability, it is necessary to have a certain voltage (or energy) per pulse
time

17. PLANON® dimming technology: Two different principles
100%
Luminance UL
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%.
50% UL
50% UL
PWM-Dimming:
PWM means „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.
