ABSTRACT 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.

LEARNING POINTS 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   

CONTROL VOCABULARY

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

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

DIMMER LOADING

INRUSH CURRENTREPETITIVE PEAK CURRENT

• NEMA 410 STANDARD
