Following application highlights the benefits of DALI practically. In the example below a typical conference room is shown, where all lights have been connected via a single DALI subnet. As the devices are digitally programmable, the Lighting Designer has chosen to create 4 x groups to virtually separate the accent lighting from the functional lighting. This gives the Lighting Designer control of each individual group allowing to creating different lighting scenes.
Since all devices are digitally programmable one can easily create different scenes, without making changes to wiring. The images below demonstrate how the room can change its ambiance at the touch of a button. More advanced functions, like scheduled events and occupancy sensors, can bring further energy saving benefits
A self-contained DALI system! A ballast and a multisensor, offering benefits such as constant light control, PIR movement-detection and IR remote operation.
The Digital Adressable Lighting Interface (DALI) is based on an international recognised IEC standard for intelligent and easy management of lighting equipment. The standard incorporates several parts that provide control and monitoring functionality for Ballasts, Emergency Gear and LEC gear; expanding to Lighting Controls in the near future.
Its digital simplicity and flexibility enables customers to create solutions that easy-to-use, robust, interoperable and above all affordable. DALI has proven its reliability for many years, and will continue to develop and support the growing demands for professional lighting.
Simply connect together components for a fully functional single-channel system. Minimal configuration is required - using either the control panel or the IR Remote Control.
The infra-red remote control or a Windows® based software can be used as an easy configuration tool to group loads together. Groups can be individually addressed, providing, for instance, zoned, localised control of task lighting within a large open-plan office.
Multiple DALI systems can be connected together utilising gateways to building management systems. Software programs offer more sophisticated programming functionality for grouped systems, such as scenesetting, timeclock, and partition control.
Having 64 addressable DALI devices is in practice sufficient for stand-alone single room lighting solutions e.g. single cell office or meeting room. However in larger installations there might be a need for integrating hundreds or even thousands of DALI devices.
In such case different manufacturers offer so called DALI gateways, which can network multiple DALI subnets (see 01). Some common examples include: ETHERNET (TCP/IP), BACNET, EIB/KNX and LON gateways. These networks offer a backbone for integrated building control to combine e.g. HVAC and Lighting. Nevertheless DALI is still important in offering a flexible, intelligent and standardised local lighting interface.
