Distributed Lighting Control


Centralized low-voltage lighting relay panels require load wiring and sensors to be run back to the central panels. In a distributed system, control groups have lower input and output counts so that they can be mounted closer to the area being controlled allowing lower installation cost. The traditional result of distributed systems result in the following issues:

  • Using a flexible enough system that can meet control needs of each distributed control zone. In many buildings the lighting needs vary from zone to zone.
  • Traditionally, one of the hardest steps with implementing a distributed lighting control system is getting it up and running after it is installed.
  • With an on/off approach, energy savings are not always maximized. Occupant satisfaction is also compromised by not taking into account individual preferences.

Delta Lighting Solutions

System scalability: With Delta Controls, use only the amount of inputs and outputs that your building needs. With switches, sensors, relays and dimming channels on different devices, a modular system that fits your building exactly can easily be accomplished. 

System programming: Through easy pushbutton programming and indicator lights that show the user what is happening, an installer can quickly do basic setup of assigning switches and occupancy sensors to associated relays to get the system up and running.  Advanced full-system programming can be accomplished through intuitive touchscreen setup screens on the device which provides scheduling and astronomical clock functionality.

Advanced dimming control: Maximizing energy savings not only relies on turning lights off when a space doesn’t need them, but also that only the required amount of light is generated.  Advanced daylighting operation and personal light-level preferences improve occupant comfort and reduce the amount of the building’s energy directed to lighting and cooling.


Having the lighting control system which can process all of the information for an area and make intelligent decisions as to how the lighting is adjusted reduces building energy costs in both lighting and cooling loads, and increases building usability by adapting the lighting to the different uses of a space.  With distributed intelligence, each piece knows exactly what it needs to do so is not impacted by other devices being offline or brought online.
