Technical Guide
2.3.8 Radiation
components in
the infra-red range
Infra-red components radiated by compact fluorescent lamps as a percentage of power
consumption:
Fluorescent lamps emit radiation at wavelengths which are also used for infra-red
transmissions. Since the IR receivers used for televisions, wireless headphones and
sound transmission systems, for example, are often not sufficiently selective there
may be interference in the IR system, particularly with lamps operated by electronic
control gear, if light or optical radiation from the lighting system enters the IR receiver.
The light emitted by a fluorescent lamp is essentially modulated at twice the operating
frequency (50 to 250 kHz in the case of electronic control gear and 100 or 120 Hz in
the case of conventional control gear). Interference may occur if the useful signal is
also operating in this frequency range.

IR remote control
Interference-free operation is possible with systems that work with a sufficiently high
carrier frequency (400 to 1500 kHz). If interference occurs in systems or equipment
operating at a lower carrier frequency, it is best to move the IR receiver as far as
possible away from the radiation footprint of the lamp or shield it from direct light.

Electronic merchandise security systems
In many shops nowadays, merchandise such as CDs and clothing is protected against
theft by electronic security systems. These systems typically operate with resonances
in the kHz range. If the operating frequency is between 30 kHz and 150 kHz it may
lead to interference. Such interference can be avoided by increasing the distance bet-
ween the luminaires and the transmitting/receiving system.
