Lighting systems, as one of the biggest energy consumers on a global scale, are being
upgraded based on innovative energy-saving (hereafter E-saving), energy-efficiency (E …

The purpose of the present paper is to evaluate the sensitivity of modern lighting
technologies to different types of RVCs. In order to do that, 27 modern lamps—mainly LED …

More and more light-emitting diode lighting devices (LED) are being connected to modern
power distribution lines. In addition to its many positive features, this poses problems in …

Designing a bright blue and red phosphor for phosphor-converted white-light-emitting
diodes would be extremely beneficial to the lighting industry. Achieving the same through …

Direct AC LED drivers have advantages over conventional LED drivers in size and cost
because of no need for bulky and expensive inductive components. However, none of …

This paper evaluates the impact of voltage distortion on the electrical quantities measured
by revenue meters and the influences on the electrical energy billing. This is done through …

In the context of the electricity crisis, measures are needed to reduce energy consumption.
The case study was conducted on the lighting system at a university sports hall. To …

In this paper, a novel approach to matrix-converter-based variable frequency drives is
presented. It is proposed that these drives are used to provide or draw out reactive power …

Road lighting is one of the most important services provided by public entities. Entities
providing such a service are interested in providing it with the lowest possible financial …

Due to changes in power networks and increased use of power electronics-based devices
as consumer loads, utilities are now facing a problem of capacitive (reverse) reactive power …
