“…In three-phase AC source also a multi-cell converter solution may be used. In this topology approach, three single-phase converters in a star or delta connection to the three-phase power grid are arranged and linked in parallel connection at the output [29]. Finally, in Figure 6a block diagram classification of ac-dc LED drivers for both single-phase and three-phase AC source are summarized.…”

In this chapter, a survey of LED driver circuits is presented. The driver circuit is a crucial component in the LED light system. It provides the correct voltage and current values for the best brightness and long life. Furthermore, the driver circuits contribute to obtaining high efficiency and reliability light system. Several lighting applications need different driver topologies that meet the use requirement and the energy sources available. In actual applications, passive and active circuits are implemented to satisfy the LED driver electrical requirements and cost-effective demands. The LED driver circuits investigation evaluate the issues and the solutions in the LED lighting systems connected to a DC source such as a battery or AC line. The AC line connection requisites such as the power factor correction and the harmonic distortion are dealt with both the driver topology and control optimization. Also, the volume reduction need is examined in the circuitry choice. Moreover, the different topologies of the power converters isolated and not isolated used in the driver circuits based on both the power request and supply source are described and critically evaluated.

“…The authors employed Manchester coding with OOK modulation to achieve the best tradeoff between lighting and data rates. In [69, 157], a 682 nm visible‐vertical‐cavity surface‐emitting laser is used to attain 10.5 Gbps downstream traffic and 2 Mbps upstream traffic using QAM‐OFDM modulation scheme.…”

“…In the recent times, a different dimension of LED research is being explored in industrial laboratories and academic research labs to enhance light extraction efficiency and communication capacity. InGaN-based QWs LED emits blue-violet spectrum coated by colour conversion materials, and this colour mixing technique makes it more efficient over the incandescent and fluorescent light sources [69]. Currently, most of the GaN LEDs are fabricated by metal-organic chemical vapour deposition machines, where the LED structure is fabricated on a single crystalline substrate [70].…”

Visible light communication (VLC) is a promising candidate for future indoor wireless communication. Light emitting diodes (LEDs) are popular choices as transmitters for VLC, since they are energy efficient and have the ability to provide illumination and data transmission simultaneously. VLC is attractive for reasons such as security, the ability to use a licence free spectrum, and broad bandwidth. Previous review articles on VLC mainly focused on VLC network algorithms, implementation challenges, system design, applications, and physical layer technologies. Unlike the existing reviews, this study presents stateof-the-art VLC systems for high-speed data communication in the gigabit range and the techniques to achieve such high data rates. In addition, concepts such as LED modelling and fabrication process, recent commercial advancements of VLC products, and hybrid/heterogeneous networks to achieve high data rate are highlighted in this study. For this purpose, some key technologies of VLC systems, including channel equalisation from both transmitter and receiver sides, higher-order modulation techniques, wavelength division multiplexing, multiple input multiple output technology, LED modelling, and advanced fabrication processes are discussed. This study also covers recent advancements in commercialisation of VLC technology, and recent progress made by various research groups.

Light-Emitting Diodes (LEDs) are coming strongly into the lighting market due to their advantages over conventional lighting solutions: energy efficient, controllable in both light and color, long lifetime, lack of a warm-up period and high power density. Some of these advantages will make LED light sources to be more than just a lightbulb, being able to transmit data, control light color, hue and intensity or even detect people in indoor environments. Nevertheless, these advantages attributed to LED capabilities are, in reality, achieved thanks to the LED driver. The present work reviews the current stateof-the-art strategies to drive LEDs from ac power grids with special emphasis into removing the most limiting component from the point of view of the lifetime, which is the electrolytic capacitor, while achieving a flicker-free performance of the light output of the LED driver. Moreover, it focuses on analyzing the required regulations, challenges and applicability of LED drivers in both single-phase and three-phase ac power grids.Note: This only applies for certified dimmable luminaires.
