8.6 Luminous rows
When planning lighting systems for commercial locations,
the type and number of lamps used is determined by the
luminance required. For reasons of cost efficiency, the
installation often consists of fluorescent tubes arranged in
luminous rows, and are divided into separate switching
circuits, according to the way the room is used.
8.6.1 Requirements for a lighting system
• The various luminous rows are switched on and off
locally.
• If there is sufficient daylight, the rows on the window side
of the roo
m are automatically switched off by means of a
daylight control switch.
• The lights are switched off automatically at 20.00 h.
• Local manual operation of the lighting must be po
ssible at
all times.
