3 What do you need from light control on your project?
5 Current Control Strategies DALI is not a complete solution.
6 Existing Control Technologies 0-10V2-Wire Phase Control3-Wire Phase ControlDALI (One type of Digital Ballast)
7 Anatomy of a Ballast Front End Back End Listens for signals from 0-10V, 2-Wire, 3-Wire, or DALIControls the lamps
8 0-10V Technology Advantages Disadvantages 4 wireAdvantages DisadvantagesMis-wire can destroy ballast or all ballasts on that circuit2 Control WiresCode limitationsSensitive to wire length and control noiseLong historyZones can be wired independent of circuitsFull line voltage available to strike lampsEasy to retrofitLow cost controlsTHD <10%ADVANTAGESEasy to retrofit because the control wires do not have to follow circuiting.Circuits and zones can be separate. Because low voltage wire is used the zones are relatively easy to re-configure.Most codes do not require low voltage wires to run through conduit. A variety of simple, direct controls are manufactured.Good power quality and low THD of less than 10%Full voltage to ballast helps means lamps strike at any setting.DISADVANTAGESBallast can be destroyed by mis-wires, in fact every ballast on the same zone can be destroyed if line voltage is wired to the low voltage control wire.Line voltage and low voltage wires lend themselves open for many different interruptions in the electrical code.Control wire length is an issue due to voltage drop as the wire is extended.
9 2 Wire Phase Control Advantages Disadvantages Easy retrofit Low cost controlsNo control wiresTHD/THC over 30%No wiring of zonesindependent of circuitsCurrent implementationshave lamp stabilityproblemsADVANTAGESEasy retrofit for one 1 circuit with small load.No control wires- dimming occurs on existing two wires.DISADVANTAGESLimited voltage: Since dimming is achieved by reducing the input voltage to the ballast and not by a control signal, the voltage is reduced thereby limiting the voltage to strike the lamps. This technology also results in high THD.May require dedicated controls. May not be able to use standard incandescent dimmer because low end trim and circuitry may not be compatible. Should consult manufacturer for compatibility.
10 3 Wire Phase Control Advantages Disadvantages Long history Full line voltage available to strike lampsTHD <10%Low control powerLow cost controlsWide variety ofcontrols availableNo wiring of zones independent ofcircuitsHigher costExtra line voltage wirefor controlADVANTAGES23 years of market acceptanceThe best power quality means the least amount of harmonic distortion i.e. less than 10%.Low control power signal means many ballasts can be controlled by a single inexpensive wall box dimmer.
11 Digital (DALI, DSI) Advantages Disadvantages 4 wireAdvantages DisadvantagesEvery fixture is addressableCan Be RetrofittedRe-zoning capabilitiesIndividual Fixture ControlStandard Power wiringPolarity and Topology freeRequires CommissioningLimited ManufacturersLimited lamp typesNo control protocol definedFailed ballast require re-commissioningADVANTAGESEasy to retrofit because the control wires do not have to follow circuiting.Circuits and zones can be separate. Because low voltage wire is used the zones are relatively easy to re-configure.Most codes do not require low voltage vires to run through conduit. A variety of simple, direct controls are manufactured.Good power quality and low THD of less than 10%Full voltage to ballast means means lamps can strike at any setting and compensate for line noise.DISADVANTAGESBallast can be destroyed by mis-wires, in fact every ballast on the same zone can be destroyed if line voltage is wired to the low voltage control wire.Line voltage and low voltage wires lend themselves open for many different interruptions in the electrical code.Control wire length is an issue due to voltage drop as the wire is extended.
12 Fluorescent Control Market Although multiple technologies are available, why is fluorescent control not widely used?Too ExpensiveToo Complicated to DesignToo Cumbersome to Maintain
13 New Product FocusMake fluorescent lighting control more cost effectiveMake fluorescent lighting control easy to design by reducing interfaces and complicationMake a lighting control system that improves maintenance.Meet and exceed benefits of existing technologies without the disadvantagesMake this a REALITY
14 Can a system that does this be simple to design?
15 Begin with 1... ...Scale to New architecture Building block approach Single Fixture, Multiple, SystemNo power packs or interfacesEverything wired together works together.Simple customization to meet different needs....Scale to

32 What can the designer expect Zoning decision can be delayed, perhaps until commissioningLower cost solutions to meet the client’s needs and energy codesNo interfacesNo miswiresOnce the ballast is specified, any controls can be added/removed/reconfigured without major redesigns
33 What can the contractor expect Control wiring free of topology and polarity issuesCommissioning done by someone either Lutron or contractorLess parts and pieces to install in the field.No interfaces to co-ordinateLess wiring timeClass 2 is not enough at 277VTraditional low voltage devices are likely lower cost than these DALI devices will be.
34 What can the owner expect Infinite flexibility of lightingNo class 1 rewiring everNo power packs or interface boxes to replace or “chase” around the buildingSimplified maintenance through reportingLegitimate return on investmentProductivity improvement through proper lighting levels and individual controlNo ballast failure reprogrammingClass 2 is not enough at 277VTraditional low voltage devices are likely lower cost than these DALI devices will be.
