The
goal of this project is to develop an enhanced DALI
lighting ballast control standard to allow for the operation
and control of a complete lighting system. The enhanced
DALI open standard would enable different manufacturers
control devices to operate on the same control system.
The lighting system includes the ballast, peripheral
lighting control devices (such as occupancy sensors,
scene switches, centralized network monitoring and photosensors).
The
Watt Stopper
is leading the research and development work for this
project. This PIER work is being done in cooperation
with the National Electrical Manufacturers Association
(NEMA).
To
realize this goal, industry consensus must be reached
among the different control manufacturers. The standard
would create predefined messages and commands that would
be embedded in the controller intelligence and allow
for seamless communication between control devices and
between the control device and the ballast.
The
objectives of this project are to:
- Define
customer needs for automatic control, manual overrides,
central monitoring and reporting, load shedding, occupancy
and daylighting control in commercial office and school
applications.
- Conduct
a technology evaluation of the DALI system to develop
a common understanding of its strengths, weaknesses,
and opportunities for using available command structure
space for standard control device commands.
- Communicate
the knowledge gained from the applications research
and technology evaluation to the lighting controls
industry and key stakeholders.

Objectives
continued:
- Work
with NEMA to build and obtain consensus among manufacturers
for a standard control command structure.
- Incorporate
the agreed upon command structure into the DALI protocol.
This
project meets the PIER Goal of improving the reliability/quality
of California's electricity by creating a control standard
that will speed up the use of DALI ballasts and control
systems.
By
increasing the adoption of the technology, more end
users will have the ability to dim and control each
fixture, which will reduce energy use and demands upon
the electrical distribution system.
