5OSRAM innovations power the marketLatest
brilliant example OSRAM PLANON
- Extremely low-profile flat-format fluorescent
lamp for area lighting
- New high performance backlighting for LCD
screens
- New design possibilities for general lighting
with outstanding uniform luminance
- Virtually constant light-output over a wide
ambient temperature range
- Mercury-free, thus no problems with waste
disposal
6PLANON system advantages
- High luminance (gt7000 cd/m²) constant from
centre to edge - High homogeneity (gt 85)
- Lamp size not limited by physical constraints,
currently available Lamp diagonals 10,4,
15,0, 18,1, 20,1, 21,3 - Integrated reflector for optimised light-output
- Mercury-free discharge thus
- light-output unaffected by changes in
ambient temperature (-30C 85C)
instant start at full light-output
(start-up time lt 5ms) no hazardous waste
7PLANON system advantages
- Extremely long lamp life, up to 100,000 h
(based on 50 of initial luminance) - no internal heater electrodes to burn-out
- no darkening caused by loss of emitter
material or mercury effects
- Colour coordinates stable over lifetime
- Lambertian characteristics
- Heat dissipation with extremely low Rth
- Inverter/ECG QT PLANON designed for
optimising lamp performance Including PFC
lamp driver, lamp driver only
8PLANON lamp structure
- The various functional layers of a PLANON lamp
9PLANON 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
10Principle of the barrier discharge
11PLANON 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

Components of a PLANON system
13Maintenance characteristics of LCD backlighting
systems
- With an estimated lifetime of 100,000 h
PLANON technology surpasses other existing
backlighting systems by far
14Burn-in characteristics of LCD backlighting
systems
- PLANON starts at high luminance within 5 ms,
offering power saving benefits by enabling true
power- save modes
15Relative light output vs. ambient temperature
- PLANON light output is virtually unaffected
by changes in ambient temperature
16PLANON dimming technologyPrinciples
- 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
17PLANON dimming technology Two different
principles
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 10050.
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.
