LEDs Allow New Remote-Controlled Lighting Applications
By: Piero Bianco, Business Manager, SPM Business Unit

Abstract: One benefit LEDs offer in general lighting applications is that they are easier to control remotely. This
application note describes a remote-controlled architectural or street-lighting system and describes how to implement
power-line or wireless communications control of a lighting system.
Remote-Controlled Applications in Street, Parking,
and Indoor Lights
As stated in application note 4670, "LEDs for General Lighting: What They Offer and Their Design in Retrofit Lamps",
LEDs offer more design flexibility for dimming and changing the light color. This versatility makes them ideal for
applications like architectural lighting, indoor ambient lighting, and dimmable street and outdoor lighting. All these
applications require a technology to control the LED light remotely. For the application to be successful in the
marketplace, the cost of upgrading the lighting infrastructure to new LED technology must be minimized. Not
surprising, solutions that can reuse the present infrastructure will likely be the first to penetrate the market.
When converting to remote-controlled LED lighting, the most costly infrastructure upgrade to anticipate is the wiring to
control the LED lights. Fortunately, LED lamps can be controlled through existing power lines using PLC technology.
PLC technology allows communication over a long range. New OFDM-based PLC technology, including emerging
standards such as G3-PLC™, is simplifying integration of lighting control applications by providing noise immunity and
interoperability.
