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 MODULE Constant Current Output

14. CONTROL TYPES - LED DIMMER TO LED DRIVER 2 WIRE DIMMING --------------------------------------- (FORWARD OR REVERSE PHASE CONTROL) 3 WIRE DIMMING --------------------------------------- 0-10V ------------------------------------------------------ DALI/DIGITALLY ADDRESSABLE -----------------

15. 0-10V CONTROL OFTEN USED FOR SWITCHING AND DIMMING 2 POWER WIRES AND 2 LOW VOLTAGE CONTROL WIRES IEC 60929 STANDARD 10V - HIGH END - DEFINED AS 100% 0V - LOW END - ??? VOLTAGE LEVELS IN BETWEEN - ???

16. DIGITAL CONTROL DALI/DALI PLUS IECC 62386 TYPICALLY REQUIRES COMMISSIONING CAN RESULT IN PROPRIETARY SITUATION – DRIVER + CONTROLLER BY SAME MANUFACTURER DMX – 512A ANSI standard ALWAYS REQUIRES COMISSIONING USED FOR FAST AND CONTINOUS COMMUNICATION, TYPICALLY IN THEATRICAL APPLICATIONS
