Installation example – Classroom

Within a classroom environment e-Sense ActiLume offers many advantages. The lighting control is adapted to the size of the room, automatically incorporating the luminaires which are positioned away from the window. Installation costs are kept to a minimum thanks to the ease of installation and commissioning.

Dimming creates the right light during lessons, whilst also savings energy. When Risbroskolan in Sweden changed their old luminaires they made energy saving of 73 %. Read more about the project

 

Within a classroom environment e-Sense ActiLume offers many advantages. The lighting control is adapted to the size of the room, automatically incorporating the luminaires which are positioned away from the window. Installation costs are kept to a minimum thanks to the ease of installation and commissioning. 

Advantages:

  • Automatic switching on/off or only switching off.
  • Daylight control.
  • Offset control of luminaires by the corridor.
  • Control by door and AV panels.
  • Control integrated in standard pushbuttons.
  • Quick programming using IR-transmitters.

Proposal for the installation of control in classrooms

Installation in a classroom with
e-Sense ActiLume. The different control functions are connected to the master luminaire, which is placed in the middle of the row by the windows. Luminaires in the row by the corridor, furthest from the incidental daylight, are controlled via the DALI 2 line, which has an offset of 30 % from DALI 1. Resulting in the luminaries furthest in the room providing more light in the dimmed state. The size of the classroom usually demands occupancy detection to be supplemented with en extra sensor which is placed centrally in the ceiling.
Ceiling lighting is controlled using the pulse switch by the door. The whiteboard lighting can also be switched off separately.

The sensor is pre-fitted in one of the luminaires in the row by the windows; acting as a master luminaire. The sensor offers occupancy detection and daylight control, which can be easily accessed via a IR-receiver and a service button. Other luminaires are connected to the master luminaire on two different DALI connections. The luminaires away from the windows are adjusted with an offset of 30 % compared to those located by the windows.

The inclusion of offset control creates a balanced illumination over the whole area, which previously was only possible using an advanced bus system. After installation, a maintained illumination level of approximately
500 lx can be achieved by pressing the service button on the sensor and activating daylight control. The desired light level and other functions can be easily changed with an IR-transmitter 86155.

Depending on the design of an older installation, energy consumption can be reduced by up to 80 %.
