Local Dimming Controls (B)
The IS45K can also be installed to allow for manual on/off control.
Adjusting the dimming level appropriately according to the type of space and its layout.
- Light dimming level is adjusted to compensate for the level of natural daylight.
- A switch can also installed for manual control by the user as needed.
Schedule decides what dimming level to set in order to save energy.
Daylit Space Dimming
The room lighting level can be manually set depending on the natural lighting level.
Energy saving dimming for public daylit rooms, such as offices and library rooms
- When daylight is sufficient, then room lights need only to be half dimmed (adjustable), if the user feels it is enough, they would not need to do anything.
- When daylight becomes dim, then the half dimmed lights are not enough, and the user may press the switch to turn the lights to full.
- With a K15 installed, if the occupant leaves the room and forgets to press the switch, then the lights will go back to being half dimmed after a short delay.
Elevator Sensor Dimming
Typical Usage: At night, hallways or elevators make use of sensors.
- Peak Period: Centralized control takes care turning the lights fully on, half dimmed or authorizing local control.
- Off-Peak Period: Local sensor control, people come, lights on; people leave, lights off.
By making full use of sensors and integrated switches, one can expect to get the potential savings as shown below. Reference: US EPA Report
