3.1 OSRAM DALI/1…10 V ECG: Added-value through intelligent features
•
Automatic lamp detection through intelligent multi-lamp operation
(reduction of the ECG type variety)
Lamps of the same length and different powers can be operated
on an ECG. Furthermore, there are special approvals for specific
ECG lamp combinations
10
•
Dimming range to 1 % of the rated luminous flux (3 % in CFL)
•
Ignition of the lamp at an ambient temperature of -25 °C
•
Optimized lamp warm start within 0.6 s [including HF DIM]
•
Temperature-dependent “cut-off” at dimmer settings > 80 %
Shutdown of the filament heating at dimmer settings > 80 % pre-
vents a permanent heating current through the lamp electrodes
during operation. This reduces the filament loading and the power
loss by approx. 2W
• Power reduction by the ECG at excessively high ambient tempera-
tures in order to protect the electronics ! Can be used in very
close, hot luminaires (operating life, increased light yield, simplified
safety approval)
•
High T

(T

•
Stable dimming operation also in amalgam lamps (CFL (IN) and
OSRAM T5 CONSTANT lamps) ! particularly suitable for use in
areas with low ambient temperatures (e.g. cool rooms, outdoors):
relative luminous flux > 90 % from 0 °C to 70 °C
• Intelligent power control upon detecting instabilities in the lamp cir-
cuit (amalgam lamp start) – protects lamp/ECG
• Permanent Heat Mode (PHM) for lighting effects (permanent fila-
ment heating, switch-on of the continuous lamp pre-heating by
digital command, not DALI standard): The PHM ensures that, at
a light value = 0 (switched off lamp(s)), the lamp electrodes are al-
ready heated. A delay-free lamp start is therefore possible
•
•
> 1 s on/off switching cycle in the PHM ! No restrictions
•
•
0.5 s < t < 1 s on/off switching cycle in the PHM ! 30 k
switching actions with T5, 100k switching actions with T8
•
•
< 0.5 s on/off switching cycle in the PHM ! 15 k switching
actions with T5, 50k switching actions with T8
• Optimized filament heating and lamp operation at mains undervolt-
age (no damage to the lamps)
