1. General

1.4.1 Radio interference

suppression

Even if used with conventional control gear (50/60 Hz), gas discharge lamps generate

electromagnetic radiation in the HF range. This radiation has such a low energy, how-

ever, that radio and television transmissions are normally not affected. The HF energy is

dissipated as radiation and via cables. The radiated energy decreases so rapidly with

distance (1/r2) that the radiation component about one metre from the source is lower

than the level of ambient noise.

To prevent interference being carried over the cables, OSRAM DULUX® lamps with

two-pin bases have built-in interference suppression capacitors:

An interference suppression capacitor is also built into the external starter used for

lamps with four-pin bases that are being operated on conventional control gear. In the

case of electronic control gear, ECG manufacturers are responsible for ensuring that

their products meet the relevant radio interference suppression requirements (CISPR 15

or EN 55015). In addition, interference suppression will also depend on the way in

which cables are routed in the luminaire; this factor may be quite considerable. The

luminaire manufacturer must ensure that the luminaire has adequate radio interference

suppression.

If an additional interference suppression capacitor is installed in the luminaire, ensure

that it is parallel with the mains and not with the lamp.
