  1. AN INTRODUCTION TODALI

  2. 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

  3. What is DALI ? (2) • 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

  4. What is DALI ? (3)

  5. What is DALI ? (4) • 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

  6. DALI - the Standard for Lighting Technology • 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

  7. Where is DALI today (1) • 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

  8. Where is DALI today (2) • 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)

  9. L N DALI DALI Technology (1) • 2 wires cable – no polarity • The DALI control line can be installed together with mains cable (e.g. by using a 5 wires standard cable)

  10. DALI Technology (2) • DALI relates to DIN IEC 60929, which defines a digital dim interface for elektronic ballast devices (ebd`s). • Standardised is: • Technical items (Current, Voltage, Timing ...) • Data protocol • Test conditions for ebd`s

  11. DALI Technology (3) • Technical Data • Data speed 1200 Baud (Bit/Sek.) • Master-Slave System without collision control • Control line with 2 wires • Interface voltage 16V (9,5V bis 22,5V) • Interface current 250mA • DALI devices needs max. 2mA • No SELV – no special cable needed • max. 64 DALI components in one system • Up to 16 groups • Up to 16 light scenes

  12. DALI Technology (4) • Functionality • Switching (ON/OFF) • Set of brightness values • Dimming via logarithmic characteristic curve (like human eye) • Fading times for scenes • Control of individual devices or groups • Synchronised dimming of all components • Simultaneous control of all devices (Broadcast-Mode) • max. / min. Dimming limits) • Status feedback (Lamp on/off, topical Brightness value, Lamp-, ebd fault) • Operation with emergency power

  13. DALI Technology (5) • The Intelligence of DALI is not centralised. A lot of adjustments and brightness values are stored in the EBD • Individual adress • Assignment to groups • Light scenes • Speed of Dimming • Switch on brightness in case of voltage recovery • Brightness value in case of emergency power supply
