What is DALI ? (1)

The subject DALI is a synonym for a standard, independent of the manufacturer to control electronic ballast devices (ebd`s) and lamps the digital way

This standard (DALI) is supported by the worldwide leading manufacturers of ebd`s since 1999.

There is a working group ( Activity Group DALI – www.dali-ag.org) to establish the DALI Standard.

Since October 2003 ABB Stotz Kontakt is a member of AG DALI and therefore authorised to assemble and sell DALI compatible devices with DALI Logo.

Members of working group AG DALI: ABB, BAG, CEAG, DELMATIC, DIAL, ECKERLE, ERC, ERCO, ETAP, GEWISS, GITRONICA, HADLER, HELVAR, HÜCO, INSTA, JOHANSON CONTROLS, LIGHTOLIER, LUTRON, LUXMATE, MAY&CHRISTE, NIKO, OSRAM, PHILIPS LIGHTING, SANDER, TRIDONIC, TROLL, UNIVERSAL LIGTHING TECHNOLOGIES, VOSSLOHGIES, VOSSLOH-SCHWABE, WILA

Task of working group DALI

- worldwide adoption of DALI- Securing the convertibility of DALI devices- Support of application of DALI

No Certification or Registration of DALI devices necessary

DALI Logo indicates the compatibility of DALI components

DALI is a stand-alone System. It is a digital control and a subsystem for lighting technology and not a bussystem

Specification is documented in DIN IEC 60929

DALI is a digital interface in lighting technology, used as a subsystem in building technology

It is supported by all manufacturers of electronic ballast devices (ebd`s)

A standard independent of the manufacturer

Specification is documented in DIN IEC 60929

DALI is more and more in use in non residential buildings

Modern and smart Lighting technology is with DALI feasible, including coulored light

For all types of lamps (e.g. halogen lamps, fluorescent lamps, bulbs, LEDs) are appropiated ballast devices available

The product range of DALI components will extend on L&B 2004

DALI-Gateways for superior building installation systems like EIB / KNX, LON ... are available

Architects for Illumination accept DALI as ideal tool for lighting technology

DALI is specified in many cases for Light moods (e.g. Doctor`s surgery)

Light effects (e.g. Show rooms)

Functional Light control (e.g. Office buildings)

Supervision (e.g. Building with Facility-Management)
