Our VisionTo help partners meet demands of lighting todays buildings by: Influencing luminaire design based on watt hours per sq ft (not just lumens per watt and watts per sq. ft.) Specifying intelligent, digital, addressable fixtures with maximum controllability to: Measure watt hours per sq. ft. Report status, current power consumption Load shed during peak demands Why Dim? Cost to generate a watt is 4 - 22 times more expensive than the cost to save a watt using dimmers (NegaWatt). ** Source: Building Dimmers vs. Building Power Plants: An Economic Analysis, Mar 2009

Technical OverviewLets Get Technical

Fluorescent Dimming OverviewBallast supplies the lamp with high voltage at both endsPhosphor coating reacts with UV photons released by the plasma arc stream and converts to visible light

Rapid Start vs. Instant StartRapid Start sockets required for programmed start allow current flow to heat the filamentrequired for dimming applications Instant start sockets only allow current to flow to the arcNot for dimming

Socket Lead LengthsLinear Lamps T8 & T5All lamp leads Maximum 7 feet (2.1m)

Compact lamps - T4 Compact & T5 Twin tube All lamp leads Maximum 3 feet (0.9m)

Good lamp pin connections is essential for dimming Using correct lamp holders is the key to reliable performanceLutron recommends using lamp holders that meet European IEC Specification 60400:superior quality more reliable connectionsSome brands of IEC compliant sockets domestically available are: -A.A.G. Stucchi-Vossloh Schwabe-BJBUsing High Quality Sockets

Ballast MountingLutron ballasts dissipate a small amount of heat and must be mounted to a flat metal portion of the fixtureThis metal will transfer the heat more effectively if it is exposed to the exterior of the fixture. Fixtures should be thermally tested with the ballast to ensure that they are thermally compatible. Ballasts must be mechanically secured to the fixture so that the ballast and fixture are electrically connected or grounded. It is a UL requirement that all parts of a light fixture be grounded. Lutron recommends using paint piercing hardware such as star washers or press-nuts to mount the ballasts. Note: Double sided tape is unacceptable for mounting ballasts.

Lamp to Fixture Separation All fluorescent lamps capacitively leak current through the walls of the lampThis phenomena is expected and compensated for in the ballast designWhen dimming a lamp, it is more critical to keep capacitive leakage within a certain range This range can be controlled by establishing minimum and maximum separation dimensions of the lamp to the ground plane (refer to ANSI C78.1&2)Note: It is unacceptable for the lamps to come into contact with metal parts of the fixture. (ANSI C82.11)Min-Max Distance of Lamp Wall from Ground Plane

Agenda:

EcoSystem is the name for technology that improves energy savings, improves the environment, and improves performance of those that use the system.EcoSystem is the name for technology that improves energy savings, improves the environment, and improves performance of those that use the system.EcoSystem is the name for technology that improves energy savings, improves the environment, and improves performance of those that use the system.Cost - installed cost, lifecycle cost, and iniatial installed cost are all different items.

Raw ballast cost is about 20% higher than our standard Eco10 ballast. We save a lot of cost by eliminating power packs and other interfacing gear to provide a lighting control system with this type of capability.

Depending upon system layout, payback can occur within 2 years.

Improved maintenance - we are developing systems that will present lamp failure data and report hours of operation. Fixtures requiring service will be easily identified remotely. Ballasts shipping today have this capability.

Failure replacement without reprogramming - DALI stands for Digital Addressable Lighting InterfaceBorn from the coordination of several European Ballast manufacturers over 10 years ago.

ADVANTAGESTechnology supports addressing and software programming.DALI wiring (2 wires) are polarity free and topology free since this comes from 0-10V ballast manufacturers, miswires were common. Making no + or side makes swapping D1 and D2 a non-issue.

DISADVANTAGESSince this technology is addressable and configured via software, than someone must do the work.Since this is a ballast communication spec how to tell the ballast how to do something, there was never a control protocol defined. No method to communicate sensor status. A central processor is required.Since DALI is a last command wins system automatic control (daylight harvesting and occupancy sensor operation) complicates programming and limits system applications.Add each sensor in one by one. Daylight is first Introduce rows and compensation setting. With just one sensor multiple rows are configured where each row saves energy and sets the right light level for the tasks.

Wallstations are third. Wallstations can be 1 button or 4 scene. Wired to any fixture, even to fixtures the wallstation will not control.

The end result - daylight harvesting and personal control intersect but each function operates independently to maximize energy savings and achieve the right light level for the tasks.

Remind about hierarchy, spend time on this slide - there are always a lot of questions. This slide, more than any other represents the real value of EcoSystem and where we are unmatched

---In school districts that build a new school theyll have one zone of control. Next year when there is room in the budget for an A/V projector, they need a lighting control system that will allow separate control of the projection screen area and audience area. EcoSystem supports this via Class 2 keypads that can be dropped in and via simple programming to separate the front from the back.DALI stands for Digital Addressable Lighting InterfaceBorn from the coordination of several European Ballast manufacturers over 10 years ago.

Complete lighting control systems must be flexible enough to cover multiple objectives since a spaces and buildings needs will change over time.
