Conclusion

3. What do you need from light control on your project?

4. Market Needs (End User)
Energy Savings • Simplify Maintenance
Greater Flexibility • LEED/Energy Codes

5. Current Control Strategies
DALI is not a complete solution.

6. Existing Control Technologies
0-10V
2-Wire Phase Control
3-Wire Phase Control
DALI (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 DALI
Controls the lamps

8. 0-10V Technology Advantages Disadvantages
4 wire
Advantages Disadvantages
Mis-wire can destroy ballast or all ballasts on that circuit
2 Control Wires
Code limitations
Sensitive to wire length and control noise
Long history
Zones can be wired independent of circuits
Full line voltage available to strike lamps
Easy to retrofit
Low cost controls
THD <10%
ADVANTAGES
Easy 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.
DISADVANTAGES
Ballast 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 controls
No control wires
THD/THC over 30%
No wiring of zones
independent of circuits
Current implementations
have lamp stability
problems
ADVANTAGES
Easy retrofit for one 1 circuit with small load.
No control wires- dimming occurs on existing two wires.
DISADVANTAGES
Limited 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 lamps
THD <10%
Low control power
Low cost controls
Wide variety of
controls available
No wiring of zones independent of
circuits
Higher cost
Extra line voltage wire
for control
ADVANTAGES
23 years of market acceptance
The 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 wire
Advantages Disadvantages
Every fixture is addressable
Can Be Retrofitted
Re-zoning capabilities
Individual Fixture Control
Standard Power wiring
Polarity and Topology free
Requires Commissioning
Limited Manufacturers
Limited lamp types
No control protocol defined
Failed ballast require re-commissioning
ADVANTAGES
Easy 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.
DISADVANTAGES
Ballast 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 Expensive
Too Complicated to Design
Too Cumbersome to Maintain

13. New Product Focus
Make fluorescent lighting control more cost effective
Make fluorescent lighting control easy to design by reducing interfaces and complication
Make a lighting control system that improves maintenance.
Meet and exceed benefits of existing technologies without the disadvantages
Make 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

32. What can the designer expect
Zoning decision can be delayed, perhaps until commissioning
Lower cost solutions to meet the client’s needs and energy codes
No interfaces
No miswires
Once 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 issues
Commissioning done by someone either Lutron or contractor
Less parts and pieces to install in the field.
No interfaces to co-ordinate
Less wiring time
Class 2 is not enough at 277V
Traditional low voltage devices are likely lower cost than these DALI devices will be.

34. What can the owner expect
