What Is DALI?

DALI stands for Digital Addressable Lighting Interface. DALI is digital technology that provides two-way data communication for lighting systems. DALI is an automation system that is widely used especially in commercial buildings.

Thanks to the DALI standard, systems such as ballasts, drivers, control units, lighting fixtures, emergency lighting fixtures made by different manufacturers can be managed with a single control system.

The international standard for DALI technology is IEC 62386 and is published in multiple parts by the International Electrotechnical Commission (IEC). Standards can be purchased from the IEC website and downloaded online.

In the DALI system, just like in a computer network, a message is sent from the center and these messages are received by each unit via addresses.

In the DALI system, the data line is made with a standard 1.5 mm2 diameter double cable. Polarity is not important. DALI power and data are carried over the same double cable. Cabling up to 300 meters can be done in one subnet. A maximum of 64 devices can be controlled on a subnet. With the help of hub/router/gateway, DALI subnets can be created for controlling more than 64 devices.

DALI is a licensed brand and membership system has been introduced to use the DALI logo on the product. In order to use the DALI logo on the DALI compatible products, the members should test or acquire the test equipment and carry out the tests in-house.

When a DALI compatible LED driver is used in an LED lighting fixture, it can now work seamlessly with the DALI system. DALI can perform commands such as on, off and dimming, which it receives via data.

DALI offers a cost-effective, simple, energy-saving lighting system compatible with future technologies. Easy to install and flexible. It saves time and resources. It is easy to maintain with its control and monitoring systems, user comfort is at the forefront.
