Solid state lighting control is a critical component of many lighting designs. The variety of possible control approaches can be confusing and a bit overwhelming. The goal of this presentation is to demystify the control vocabulary and provide a better understanding of the positive and negative attributes of each of the various approaches to solid state dimming. The concept is to have a role play situation, with a lighting designer and a controls rep discussing best approaches to various applications. The rep will be assisted by a ventriloquist dummy - everytime the rep uses tech speak to explain something, the dummy will translate it into very understandable language.

4.  Solid state lighting control is a critical component of
many lighting designs. The variety of possible control
approaches can be confusing and a bit overwhelming.
 The goal of this presentation is to demystify the control
vocabulary and provide a better understanding of the
positive and negative implications of using each of the
various approaches to solid state dimming.

5. Attendees will learn the different approaches and technologies involved
with control of solid state products and the associated terminology
Attendees will learn the positive and negative aspects to each approach
Attendees will learn the cost/install implications of each approach
Attendees will learn the basics of building a network for building control
Attendees will learn code compliance requirements as applied to controls

7. FORWARD PHASE/LEADING EDGE
• INCANDESCENT STYLE
• MOST COMMON DIMMER TYPE
• LEAST EXPENSIVE DIMMER TYPE
• INRUSH ISSUES DUE TO CUTTING INTO THE
HALF CYLCE WHEN TURNING ON

8. REVERSE PHASE/TRAILING EDGE
• ELECTRONIC LOW VOLTAGE (ELV)
STYLE
• OFTEN PERFORMS BETTER THAN
FORWARD PHASE
• LESSENED INRUSH ISSUES DUE TO
CUTTING INTO THE HALF CYCLE
WHEN TURNING OFF

10. INRUSH CURRENT
REPETITIVE PEAK CURRENT
• NEMA 410 STANDARD

11. LED DRIVER TO LED MODULE
CONSTANT CURRENT – 1:1 SITUATIONS
CONSTANT VOLTAGE – LINEAR SITUATIONS

12. CONSTANT VOLTAGE DIMMING
Constant Voltage Output

13. CONSTANT CURRENT DIMMING METHODS
PWM – PULSE WIDTH MODULATION –
RAPIDLY TURN POWER ON AND OFF
CONSTANT CURRENT REDUCTION – STEADY
REDUCTION OF CURRENT TO THE LED
