Installation of light control in a classroom
A classroom is a workplace for both teachers and pupils. Good light-
ing is essential for the varying work. Through advances in lighting
technology a combination of preferable light levels and energy
eciency can be oered through controls. The right distribution
at the right level of light contributes towards a better learning
environment.
Advantages:
Automatic switching on/o or only switching o.•
Individual control and adjustment of the ceiling and smart board •
lighting.
Daylight control.•
Control by door and AV panels.•
Control integrated in standard pushbuttons.•
Lighting scenes.•
PC programming.•
Proposal for the installation of control in classrooms
Programmable control in a classroom allows exact control opera-
tions to be produced which directly correspond with the user
requirements. Maximum and minimum levels can be changed and
the luminaires can be programmed individually. Switching func-
tions can be changed and adapted to the function of the room.
Programming requires the temporary connection of a computer
with a Windows-based PC program. The possibility exists to transfer
program functions from one classroom to the next, which means
all functions are the same and the time for programming is reduced
significantly. Other advantages can be achieved by connecting the
heating and ventilation to the occupancy control. See the wiring
diagram below.
Installation in a classroom with DALI
DIGIDIM. Programming via a PC-
program. Power supply can be used
from Helvar’s EL-si DALI HF-ballast. The
dierent control functions have been
connected in parallel to the DALI control
cables. All luminaires are controlled in
common via a daylight sensor, except
the whiteboard lighting. Lighting is
switched on manually. All lighting is
switched o together. The size of the
classroom determines whether one
multisensor is sucient for occupancy
detection, or whether the installation
needs to be supplemented with addi-
tional units. The ceiling and whiteboard
lighting can be controlled individually
by the input units connected to the im-
pulse switch by the door and AV panel.
