Day Lighting >> Day360™ – GLC
Group Lighting Controller (GLC)
Daylighting is integrated to existing building Electric Lighting
GROUP LIGHTING CONTROL system is integration of building daylight systems (viz. Lightpipe or Norikool) with electric lighting so that the electric lighting is switched off when the desired lux level is satisfied by daylighting systems. Here the daylighting systems are different and electric lighting systems are different and both of them are integrated by lighting control hardware installed at some convenient location.
1. Daylighting System: Lightpipe (or) Norikool
2. Lighting Controls:
A). Daylight Sensor:
The Daylight sensor housed in Sunlight collector continuously measures the ambient Sunlight and gives a feed back to lighting controller
B). Lighting Controller (On/off or Step Switching)
Method 1: ON/OFF LIGHTING CONTROLLER
Depending on available daylight, the lights turn on when daylight level reduces below the set point without any delay. The lights turn off when Daylight is above set point after the preset delay time.
Method 2: STEP SWITCHING CONTROLLER
The electric lamps are divided into 3 groups or 2 groups. Depending on available daylight, the number of groups of lamps (1 group | 2 groups | 3 groups) of lamps are switiched on to compenstae the loss of daylight. The system works vice cersa swiching off electric lamps in steps when Daylight is increasing.
3. Energy Management System :
The Control panel records the energy consumption of Electric lighting and gives the savings obtained. The data is available in daily/monthly/yearly basis in excel or graphical form. Remote access of data is possible.
