4 Additional properties of dimmable
control gears from OSRAM

4.1 OSRAM DALI/1…10-V ECGs:
Added value through intelligent features
—
Automatic lamp detection through intelligent multi-lamp
operation (reduction of the ECG range of models)
— Lamps of the same length and various outputs can
be operated on a single ECG. Furthermore, special
approvals exist for certain lamp/ECG combinations.
9)
— Dimming range up to 1 % of the nominal luminous fl ux
(3 % in the case of CFL, also HF DIM)
— Ignition of the lamp at -25 °C ambient temperature
— Optimized lamp warm start within 0.6 s (also HF DIM )
— Temperature-dependent “cut-off” in case of dimmer
settings > 80 %
— Shutting down the fi lament heating at dimmer set-
tings > 80 % avoids a permanent heating current
through the lamp electrodes during operation.
The load on the fi laments and the power loss are re-
duced by approx. 2 W as a result. “Cut off” is not ac-
tive at low temperatures, which makes operating the
lamp easier for conventional lamps

and amalgam
lamps.
— Intelligent temperature management
— Power reduction control through the ECG to protect
the electronics in case of excessive ambient temper-
atures
➔ Use is possible in extremely tight, hot lumi-
naires (lifetime, effi ciency increase, approbation)
Note
— The ECG measures its internal temperature on the
intermediate circuit capacitor (electrolytic capacitor)
1 x per minute. It begins to reduce the power at
84 °C to lower the internal temperature of the lumi-
naire and maintain the temperature of the electrolytic
capacitor at 84 °C. The t
c
temperature remains be-
tween 75 °C and 80 °C, depending on the installation
conditions (heat coupling from above or below). At
an ambient temperature of 25 °C (in the room, e.g.
offi ce), a reduction in the ECG power by 10 % is also
suffi cient for hot luminaires. Very little light is lost in
the process because the effi ciency of lamps and EC-
Gs is improving.
➔ Most effi cient energy savings
measure compared to normal operation.
— High t
c
point values (t
c
= 75 °C) enable operation at
high ambient temperatures (t
a
values).
—
Stable dimming operation even in amalgam lamps
(CONSTANT lamps)
➔ Especially suitable for use in
areas with low ambient temperatures (e.g. cold stores,
outdoor areas) or high temperatures
— Intelligent power control when detecting instabilities
in the lamp circuit (amalgam lamp start) preserves
the lamp and ECG
— Optimized fi lament heating and lamp operation in
case of mains undervoltage (no damage to the lamps)
— EOL shutdown after test 2
— Asymmetric power test for detecting defective lamp
electrodes or high-impedance lamp sections, e.g.
through leakages in the glass tube
— Chip ID (CIN = Chip Identifi cation Number, series num-
ber) for easy system installation
➔ OSRAM DALI magic:
Address allocation is possible via CIN
— EEPROM for ensuring settings/parameters even in the
event of power failure
— Lamp replacement without mains reset (automatic re-
start of lamps after lamp replacement, including HF
DIM)
— DC operation in the input voltage range of 154–276 V/
lamp start above 198 V (i.e. no lamp ignition e.g. at
170 V DC)
— Optimized radio interference supression: Compliance
with the required EMC specifi cation limits with a com-
fortable safety margin to make it easier to install the lu-
minaire (including HF DIM)
— DALI standard according to IEC 62386 - 101/-102/-201
— 1…10-V standard according to IEC 60929
