DALI
Packed with functions but easy to use.
The DALI interface standard
If the lighting control system, sensors, controllers,
electronic control gear and light sources are to work
together at peak performance they must be able to
communicate with one another without restriction
and react accordingly. A common interface for all the
components within a system is therefore of enormous
importance.
What is DALI – and how does it work?
DALI – Digital Addressable Lighting Interface – is a
non-proprietary interface standard for digital dimmable
electronic control gear, offering greater functionality and
greater ease of use. A maximum of 64 DALI ECGs can
be controlled with a high degree of flexibility via a 2-wire
control line individually or jointly and in up to 16 groups.
The lighting is switched and dimmed via the control line.
In other words, there is no need for any relays.
Important information such the lamp status is stored in
the control gear and is available to the controller. DALI is
an interface for all professional lighting solutions. OSRAM
offers a wide range of DALI ECGs for fluorescent lamps,
compact fluorescent lamps, tungsten-halogen lamps,
metal halide lamps and LEDs.
