Chapter 16

Control Systems

Abstract

Chapter 16 discusses dimming control systems, both linear and digital. Linear systems include 1–10 V analog voltage and triac dimming. Digital systems include DALI, DMX, LIN bus, and CAN bus. The digital systems provide the pulse width modulation dimming signal to the constant current LED drivers. Wireless systems using Bluetooth or Wi-Fi are also possible.
