This Application Note from Maxim describes the implementation of ambient light sensing, communication, and energy measurement into LED lighting systems for energy conservation and lower operating costs. It explores the critical design considerations of adding ambient light sensing, communication (both wireless and powerline), and energy measurement to LED lighting systems. Reference design examples are also presented.

Ambient light sensing, communications, and energy measurement make up the critical components of an intelligent lighting system. Ambient light sensing allows lights to dim when other sources of light already light a space sufficiently. In addition, sensors that detect the color of ambient light permit color tuning of advanced RGB LED lighting systems. Communication permits remote control and central networking of both small and large lighting installations. Energy measurement provides accurate accounting of consumed power and system insight for predictive maintenance.
