8.4. DALI
8.4.1. Description
DALI standard
DALI (Digital Addressable Lighting Interface) is an interface protocol for digital communication between electronic lighting
equipment.
The DALI standard was developed by Tridonic together with renowned manufacturers of operating and control equipment. Today,
these manufacturers belong to the DALI Activity Group which promotes the use and further development of DALI.
The DALI standard is defined in IEC 62386. A test procedure standardised by the DALI Activity Group ensures compatibility between
products from different manufacturers. Tridonic products have undergone this test and meet all the requirements. This is indicated by
the logo of the DALI Activity Group on the device.
The agreement by the lighting industry to adopt a common protocol has opened up a virtually unlimited number of options. With the
right choice of individual DALI components an extremely wide range of requirements can be met, from operating a simple light switch
to lighting management systems for entire office complexes with thousands of light sources.
DALI in Action
DALI offers a lot of possibilities:
Technical data of a DALI line:
I
NOTICE
LCA PRE devices support the new DALI standard V2 (according to EN 62386-102).
DALI line: 64 LED Driver can be grouped to a line
_
DALI groups: Every LED Driver can be attributed into 16 groups
_
Addressability: All LED Driver are individually addressable
_
Grouping: Possible without complicated rewiring
_
Programmability: Individual programmability makes it possible to use functions which transcend the DALI standard
_
Monitoring: Easily possible thanks to status feedback
_
Wiring: Simple wiring with five pole standard cables and a cable length of max. 300 metres
_
Wiring: Polarity-free control lines can be used for mains and control lines
_
Wiring: Multiple wiring possibilities (star, series and mixed wiring)
_
Unaffected by interruptions: All luminaires receive the same, unaffected digital signal and dimming level
_
Similar light level from first to last luminaire
_
DALI voltage: 9.5 V - 22.4 DC
_
