The DALI interface standard is standardised in the DIN IEC 60929 covering
electronic ballasts. Due to the large range of functions and application
possibilities of DALI, the DALI sections are currently being extracted from
the standard and written into a separate standard designated as DIN IEC
62386. With DALI, a standard has been created which meets the
requirements of modern lighting technology due to its digital possibilities.
The essential functions are:
•
Individual dimming speeds for each device
•
Lightscenes with fade times
•
Scene devices reach their final brightness value simultaneously
•
DALI ballasts have a dimming range of 1 to 100%
•
DALI uses a logarithmic dimming curve
•
Current brightness values and ON/OFF states can be queried
•
Ballast and lamp faults are detected
•
Behaviour in the event of a system fault can be defined
•
Feedback such as lamp and ballast faults
•
Global control of all DALI devices (broadcast mode)
DALI has established itself since 1999 as a manufacturer-independent
interface standard. There is a wide range of equipment available with the
DALI interface. ABB has a corresponding range of ballasts, transformers,
relays, dimmers and actuators (refer to ABB main catalogue chapter 14
"Lighting equipment"). It is possible to control fluorescent lamps,
incandescent lamps, LEDs etc. via DALI, combine them into lightscenes and
to integrate them with the ABB i-bus® DALI-Gateway DG/S 8.1 and DG/S
1.1 in the EIB / KNX building installation.
The DALI standard can be seen as a subsystem of modern building system
technology which links the components of lighting technology and is not
dependent on a single manufacturer.
In the supplied state, the equipment with DALI interfaces generally behaves
so that the luminaires light up with maximum brightness the first time the
operating voltage is applied or after voltage recovery. This "Power UP Level"
is defined by the ballast manufacturer.
In the supplied state, the equipment with DALI interfaces generally behaves
so that the devices switch to emergency lighting mode and the lamps light
up with maximum brightness in the event of a DALI voltage failure. This
value can be programmed by the DALI-Gateway DG/S 1.1.
