7
We’ve moved past analog!
ˈanlˌôɡ/ adjective 1. relating to or using signals or information represented by a continuously variable physical quantity such as spatial position or voltage.
8
We are in the age and we’ve moved past analog in almost every way…….
9
Except for Dimming!!!!
10
Why are we still controlling solid state lighting with an analog signal?
11
It’s like designing a Printed Circuit Board
12
On a Drafting Table!!
14
It’s time to move dimming to Digital!
15
It’s time to move dimming to Digital!
And Digital in Lighting is
16
It’s time to move dimming to Digital!
And Digital in Lighting is DALI
17
It’s time to move dimming to Digital!
And Digital in Lighting is DALI
18
What is DALI? DALI = Digital Addressable Lighting Interface
It is a communication standard designed specifically for lighting.
19
What is DALI? DALI defines how each component in a lighting control system communicates. True 2-Way Communication!
20
DALI is also an “Open” standard. Why is that important?
What is DALI? DALI is also an “Open” standard. Why is that important?
21
What is DALI? As an open standard any manufacturer can create devices that communicate using DALI.
22
What is DALI? For example a DALI driver from one manufacturer will work with control stations, sensors, etc. from any other manufacturer using DALI.
23
What is DALI? Levels the playing field
End user creates the exact system for their needs OEM’s have to become more innovative with their products More focus on design and customer service
24
What is 0-10v? A varied input from 0 to 10v One way communication
The scale for 0-10v values are set by the individual manufactures.
25
What is 0-10v? A varied input from 0 to 10v One way communication
The scale for 0-10v values are set by the individual manufactures.

28
So why isn’t it used more in the United States?
29
So why isn’t it used more in the United States?
The Drivers are more expensive than 0-10v Drivers
30
So why isn’t it used more in the United States?
The Drivers are more expensive than 0-10v Drivers
35
$4 to $6 premium on DALI Drivers
Harvard Technology $4 to $6 premium on DALI Drivers
36
So why isn’t it used more in the United States?
Installers don’t have experience with DALI

Lutron Eco System
39
Lutron Eco System Is DALI!!
40
Lutron Eco System Or rather based on DALI. It has been modified to be proprietary, but still retains all of the functionality of DALI.
41
The real reason’s its not used more
42
The real reason’s its not used more
Early DALI Systems were a nightmare to commission!
44
The real reason’s its not used more
Early DALI Systems were a nightmare to commission! Lighting Control manufacturers didn’t see the need for DALI!!!

Human Centric Lighting (HCL) DALI vs. 0-10v
85
HCL with 0-10v In each fixture!
86
HCL with DALI
87

88
0-10v scale set by the manufacturer
HCL with 0-10v 0-10v scale set by the manufacturer
89
Human Centric Lighting (HCL) DALI vs. 0-10v
Exact color temperature no matter how long the wire runs. 0-10v Color temperature changes with long wiring runs
90
Human Centric Lighting (HCL) DALI vs. 0-10v
Exact color temperature no matter how long the wire runs. Exact color temperature on fixtures from different manufacturers 0-10v Color temperature changes with long wiring runs The same command sent to fixtures from different manufactures will produce different color temperatures.
91
Human Centric Lighting (HCL) DALI vs. 0-10v
Exact color temperature no matter how long the wire runs. Exact color temperature on fixtures from different manufacturers Less Components and cheaper to install 0-10v Color temperature changes with long wiring runs The same command sent to fixtures from different manufactures will produce different color temperatures. More components, more complicated to install
