7.5.1 Recommended
Minimum Distance
between Lamp and
Reflector
The maximum recommended base temperature of 120 °C may never be
exceeded (see
Section 7.5).
A distance of less than 3 mm between lamp and reflector can result in
generation of noise even in luminaires with non-dimmable ECGs.
At a distance of less than 6 mm between lamp and reflector the leakage
current of the dimmed lamps 35 W, 49 W and 80 W causes visible
differences in brightness between the ends of the lamps. In addition, the
radio interference suppression is getting worse.
OSRAM recommendation:
In general, OSRAM recommends to keep a
minimum distance of 6 mm
between lamp and reflector.
In certain cases (unfavourable capacitive interference) the minimum
distance should be even greater.
7.5.2 Recommended
Minimum Distance
between two
T5/
∅16mm-
Fluorescent Lamps
OSRAM recommendation:
1. For high luminaire efficiency the distance should be at
least 48 mm between the two lamps (approximately two
fingers should fit between the lamps)
2. When designing the luminaire for minimum distance the
maximum recommended base temperature of 120 °C
may
never be exceeded.
Exemptions:
Interference between dimmable ECG-lamp circuits in parallel configuration
can cause flickering. Therefore, we recommend a minimum distance of
120 mm (from lamp axis to lamp axis) between two lamps in a dimmable
two-lamp luminaire where two dimmable single-lamp ECGs are used. Or in
other applications where multiple dimmable ECGs are used in parallel such
as RGB-applications in illuminated ceilings.
If the wiring is done very carefully a minimum distance of 50 mm (between
the two lamp axis) can be achieved.
32 mm
