Background

Digital lighting control system application: Medium to large commercial enterprises and restaurants, and other large open spaces, where the lighting and air conditioning circuits are widely spread out, to save energy, everything must be centralized.

Each business activity would have its own lighting scene, with the appropriate lights in the building, both internal and external, turned on or off to match the scene.

Facilities

Traditional vs. Digital

Using the traditional approach, a staff needs to run all over the building just to control the lights and the air conditioning, this makes it impossible to do in a timely manner, so a compromise approach is used wherein the lights are turned on during office hours and turned off after office hours. Since the lights are difficult to manage, this results in unnecessary and wasted energy.

Space Saving

(1) Requires less conduit space:

A single pair of signal cable is needed to go through the entire building.

(2) Highly expandable:

Expansion can be done through the existing cable network, with a touch panel, additional lighting circuits do not require additional switches or cables.

Touch panels are used for centralizing controls for ease of operation.

Local Switches

Solution 1: Digital switches connected using digital bus cable.
Solution 2: Classic switches connected using signal cables.

Digital Lighting Network Failure Backup Mechanism

What to do in case of a system failure?

Local button control and manual relay switch
  1. Each controller module has its own set of control buttons for each lighting circuit that it controls, modules with external relays also have their own manual relay control switches for backup control.
  2. The failure of any one device will not affect the functionality of other device in the system.

  1. The actual relay used is at least twice the rated capacity.
  2. Product is CE certified.

Control Methods

On/Off Switching Mode

A portion of the lights are turned off or on at preset times.

Multi-Level Dimming Mode

The light dimming levels are adjusted automatically either from a fixed schedule or in combination with a daylight sensor

Software Design

touch panel
  1. The software on the touch panel is designed using the standard touch panel software and needs only simple configuration.
  2. No need for a specialist software engineer.
  3. To make changes, email a form with the current site changes to DAE for processing.
  4. Update the firmware using a USB flash drive.

Scheduler

It is not necessary to rely on electromechanical timers as the touch panel is equipped with a automated scheduler that can be easily set by the user to meet the need of any incidental event.

Multiple Centralized Controls

Sometimes the building manager needs to control the system from more than one location.

(1) Security office and control room in sync.
(2) The administrator is not in the control room, they can still move around with a mobile or tablet, or control from a PC.
(3) Sometimes it is necessary for the lighting control system to integrate with the building management system, the BMS can issue commands to the lighting control system and receive status feedback.
(4) A campus may have multiple buildings, during office hours, each building operates independently; but after office, all the buildings revert to central control.
