“…The development of lighting that uses LED (light-emitting diode) technology has enabled the replacement of high-pressure luminaires with luminaires that consume significantly less energy [3,4]. The advantages are [5][6][7]: high luminous efficacy, long life, instant start-up, dimming possibility, lower environmental impact, and decreased investment and maintenance costs.…”

The paper analyses the power-quality effects of connecting LED luminaires to street lighting installations. The power quality impact of LED luminaires and the implementation of smart control systems are discussed. Several power-quality measurements have been performed to determine the effect of connecting multiple LED luminaires to the electrical power network. Three LED street lighting systems were selected, each equipped only with LED luminaires of different power ratings and numbers, produced by different manufacturers. The measurements were performed at the lighting connection box, and the results are presented and discussed for each case.

“…TREET lighting generates a significant cost of maintaining road infrastructure in cities [1]. The development of luminaires using LED (light-emitting diode) technology has enabled the replacement of traditional light sources with luminaires that consume significantly less energy [2,3,4]. There are some undeniable advantages of this type of light sources such as: compact design, long service life of LED luminaire and above all low energy consumption [5].…”

More and more street lighting deployments use LED technology as a light source. Unfortunately, the new technology also brings some challenges with it that remain unnoticed until installed at scale. This article presents issues related to capacitive reactive power consumed by LED luminaires. The problem is even more profound if the luminaire is dimmed, because it consumes capacitive reactive power, which is very undesirable in the power system. Countermeasures in terms of reactive power compensation for a luminaire working with variable power and their effects are also presented. The article also contains the results of the harmonic analysis of the LED luminaires current for full power and dimmed operation.

LED lamps are projected as prospective successors of incandescent lamps with high efficiency and a long lifetime. Therefore, there is a need to develop energy efficient LED driver topologies for achieving constant current regulation, despite the effects of temperature on the LED V-I characteristics. This paper presents the salient features of various LED driver topologies with a focus on power density, multi-string operation, renewable energy utilization, soft switching, optical wireless communication, reliability and size. The performance of the above topologies is analysed in terms of the number of components, converter switching frequency, galvanic isolation, power rating and efficiency. This paper takes a look at efficiency improvement methods while dwelling on aspects of lifetime and reliability prediction of LED drivers. The paper will anticipate some of the future trends associated with the adaptation of wide bandgap power semiconductor materials, smart LED lighting for the internet of things (IoT) and programmable LED lamp drivers. This detailed technology review is extremely useful for researchers, designers and engineers in choosing the right topology.
