Television-suitable lighting in the chamber of the Federal State Parliament of Thuringia
Requirements to be fulfilled by the lighting system
In order to guarantee a television-suitable lighting, a sufficiently high
lighting level as well as a well-balanced ratio of horizontal to vertical
illuminance are extremely important. These factors are decisive for
obtaining good-quality, crisp and shadowless camera images presenting
an excellent colour rendering and brilliance during broadcast.
Furthermore, the members of the parliament need to be provided
with a pleasant, nearly glare-free lighting of their workplaces tailored
to the tasks to be carried out to guarantee efficient working free of
signs of fatigue. Here, special importance is attached to the good
recognition of the speaker's face especially in the near area around
the lectern.
The lighting system in the chamber should also provide a sufficiently
high and relatively even luminous intensity distribution in the area of
the seats of the members of the parliament so as to allow them to
do carry out their tasks efficiently.
During the realisation of the required light parameters, however,
another aspect had to be taken into account as well. The architectural
design of the chamber was not allowed to be affected too
much. Therefore, only well selected luminaires were used.

Simulation
|
On the basis of some rough details of the spatial layout and the
arrangement of the seats in the chamber, a modelling was carried
out employing the reflector lamps and luminaires already in use. In
order to guarantee a television-suitable lighting, various situations
were calculated and evaluated. Some of the existing luminaires were
adapted, and some others were replaced with new devices providing
a well-defined luminous intensity distribution. At the same time, some
additional reflector lamps were integrated into the ceiling. Some of
the results obtained are summarized in the following
file.
