    3. 3. DALI – the simple, versatile digital lighting solution DALI = Digital Addressable Lighting Interface DALI is an international standard created specifically for digital lighting control DALI provides a single interface for all electronically controlled light sources in an easy-to-install and versatile system DALI promises flexibility in design, and ease of installation DALI provides almost unlimited scalability of lighting control systems DALI is cost-effective through energy-savings and is easy to manage Created by Europe’s leading lighting manufacturers and is firmly established all over the worldSource: DALI-AG
    4. 4. History: Founded in Europe Tridonic and others » Digital Serial Interface (DSI) ballasts in 1991 » Digital Addressable Lighting Interface (DALI) ballast in 1998 » Dropped royalties to gain wide spread acceptance of DALI IEC » DALI protocol (IEC Standard 60929, Annex E & G) advanced to voting process in year 2000. » Adopted by other leading ballast and control manufactures » Formally adopted summer of 2002
    5. 5. History: Came to USA (and the world) NEMA Controls Council » Wiring Devices, Controls, and Ballasts » Liaison with International Electrotechnical Commission (IEC) » DALI subcommittee IESNA Controls Subcommittee » Established to develop a control protocol » Reviewed several existing systems » Asked by NEMA to comment on DALI proposal A true GLOBAL and OPEN standard
    7. 7. What is DALI? DALI is not a product DALI is a protocol, a set of rules defined from ballast perspective » Power connection » Lamp response » Control interface » Command set
    8. 8. Benefits of DALIInternational standard Versatility Interchangeability of different manufacturers’  Freely addressable DALI operating devices for equipment scalable lighting scenes (from workplace to room, to Designed specifically for commercial and architectural floor, to building) lighting  Lighting group configuration and reconfiguration by Future-proof software (no hard-wiring and rewiring)  Interoperability with building management systemsCost-effectiveness Intelligent lighting management (maximizing service life Digital system and saving energy)  Distributed intelligence (no external switching Low installation costs (simple wiring, fewer and low- relays, local storage of up to 16 lighting scenes on cost components) one DALI operating device) Low maintenance costs  Automated functions (e.g. sensor controlled dimming and switching)Simple planning and installation  Individual status reporting Single-cable solution (no additional bus cable required) Simple wiring (no observance of polarity, any topology) Flexible lighting designSource: DALI-AG
    9. 9. Benefits of DALI Lower initial cost to the Owner » Simple wiring Higher level of maintenance to the Facility Manager » Status of lamp and ballast Greater flexibility to the Lighting Designer » Change grouping via software Lower energy costs to the User » Reduced power consumption Greater sense of control to the Occupant » Individual control
    10. 10. Benefits for architects Ability to Mix and match » All major manufacturers offer DALI-compliant lighting control devices which are available for all kinds of light sources – offering freedom of choice » Architects can combine lighting solutions from multiple manufacturers and use different types of luminaires in one installation, allowing more artistic freedom Scene-based lighting » Using different lighting scenes, the mood and function of rooms or areas of a building, or even the character of a building itself, can be changed at the touch of a button Meeting people’s needs » Good lighting meets the visual, emotional and biological needs of the people using a building » Optimum conditions can be created by means of automated dimming and switching, using daylight and occupancy sensors, for exampleSource: DALI-AG
    11. 11. Benefits for specifiers Cost-effective » Fewer components and simple wiring, systems offer intelligent scene-based lighting management at low cost » Luminaires are grouped using software instead of hard-wiring allows changes to be made at any point up to the commissioning stage purely by reprogramming, without the expense of redesigning or rewiring Versatile » Replaces inflexible 1-10V analogue systems » Control individual luminaires, light groups and networks » Luminaires can be freely assigned to different groups to create flexible lighting scenes for workplaces, rooms, floors and buildings » Interoperable with all building management systems » Lighting scenes can be configured, reconfigured, saved and called up again on a central computer, meeting changing requirements with total flexibility throughout the system’s life Simple and intelligent » Single interface for all types of electronic control gear (ECG) and lighting control devices » Light fittings from any manufacturer and of any load type can be used in one installation, as long as they are fitted with DALI ECG, removing the constraints created by proprietary systems » Local lighting intelligence of the ECG, fewer controls are necessary for changing lighting scenes and even first-time users can quickly learn to operate groups of lights Source: DALI-AG
    12. 12. Benefits for installers and electrical contractors DALI is not only easy to install, but also extremely cost effective, saving both time and resources Wiring made simple » Single-cable digital system » Wiring is done using only a standard mains rated 5-core cable that handles power supply and DALI communications, so no separate bus cable or special tools are required » Offers complete freedom of topology, DALI avoids the wiring errors common with 1-10V systems Digital means simple and flexible » There is no need to wire luminaires in groups » The system is simply programmed and, if requirements change, it can be reprogrammed, thus avoiding costly rewiring » Switching relays are unnecessary because switching is done locally by the ballasts themselves » DALI can easily be integrated into a building management system by means of a simple gateway interface » Testing, fault-finding and commissioning are simplified and time is saved thanks to central monitoring of luminaire statusSource: DALI-AG
    13. 13. Benefits for building owners and facility managers DALI offers cost effective sustainability, ease of use, central monitoring and occupant-comfort Cost-effectiveness » Keeps running costs low through intelligent management of lamps and ballasts (i.e. dimming and switching) to maximize their service life, saving energy and reducing replacement costs Sustainability » Versatile and scalable enough to accommodate any changes in room uses and lighting requirements throughout the life of the building Ease of use » Easy to operate and provide a high degree of convenience - configured flexibly for task-related lighting scenes and reconfigure without rewiring when tenancies change » Permits extensive automation of lighting using daylight sensors, time controls and occupancy sensors Central monitoring » DALI’s 2-way digital communications feature system monitoring, status feedback and fault reporting, thus reducing maintenance costs, and enabling lighting groups to be reconfigured centrally and integrates as a sub-system in the building management system Occupant comfort » Occupants enjoy a pleasant working environment due both to the ease with which they can change lighting scenes and to automated comfort features, such as dimming and switching in response to ambient light levels and occupancySource: DALI-AG
    14. 14. DALI vs. Proprietary Digital Bus The market is confused and searching for a solution One group wants a single vendor solution for security and guaranteed compatibility » Most single vendor solutions lock a project into a proprietary solution with higher price and limited options Another group wants an open/standard solution for competitive pricing and broader options » Many open solutions have compatibility challenges and open the project to finger pointing
    15. 15. Crestron DALI Solution Single Vendor = Single Point of Responsibility and Response » Crestron supplies Ballasts, Controls, Sensors and Systems beyond DALI » Crestron takes full responsibility for start-up and commissioning of the entire Crestron system » Designer and Contractor are secure because there is “one throat to choke” Open Standard = Competitive Pricing and Broader Choices » True DALI solution – member of DALI and fully compliant » Competitive to every other DALI manufacturer – No single source cost premium » If the application requires components beyond those supplied by Crestron, the world of DALI is open to the design
