Smart LED Lighting using GaN-based “Discrete” Power and Data Sequential Co-Transfer Network

Abstract

Lately, patent-pending sequential high-frequency (HF) discrete power and discrete data co-transfer network has experimentally been proven to simplify and improve the data transfer efficacy in pulsed-power applications. In this paper, possibility of employing this network for smart LED lighting application is outlined. Incorporating sequential co-transfer network in the LED lighting system can add to the intelligence of the system in terms of its response to the prevailing environmental conditions and customer demands. In the present paper this scheme has been explained using a simple, single-input single-output (SISO) system. Various modes of operation are explained and experimental results demonstrating the sequential co-transfer approach for the LED lighting system is provided. Detailed design, advantages and challenges of designing a smart LED lighting system with GaN-FET based distributed SISO/SIMO/MIMO power-converter networks are discussed in this paper.
