“…Most of the initial LED drivers were based on the switched-mode voltage sources, and it has been necessary to design new suitable circuit topologies that can be used as current sources for LED applications, the most common power methodology [26]. Thus, high-efficiency high-reliability converters optimized for LED-based applications have been proposed in the recent years, including different dimming, power factor correction (PFC), harmonic-reduction units and control techniques.…”

Abstract:In this work, a practical methodology is proposed to analyze, before undertaking a large investment, an outdoor lighting installation renewal with light-emitting diode (LED) luminaires. The main problems found in many of the luminaires tested are associated with inrush peak currents in cold start (which may cause ignition problems with random shutdowns), the harmonic distortions caused by their AC/DC associated electronic nature driver, and their working and efficiency dependency on the ambient temperature. All these issues have been tested in the context of a large metal halide (MH) to LED luminaires lighting point renewal where six commercial LED projectors have been analyzed with the above considerations. This research has isolated a single-phase circuit powered with constant stabilized 230 V AC voltage source in a real public lighting installation. All of them have been sequentially installed and their main electrical and power-quality parameters measured and recorded. The results indicate that each luminaire option will influence the expected long-term reliability (>50.000 h or more as expressed by the U.S. Department of Energy) of the lighting installation (in the case poor power quality is generated on the grid). The economic analysis made to estimate the profitability of the investment may be severely affected by the difference between the declared and the real consumption values in which they perform in our specific installation.

“…Boost-buck is a typical design, depicted in Figure 4 in which the boost stage operates as a PFC, and the buck stage converts down and regulates the LED current. Given the vast amount of possible AC LED driver designs available, it is recommended to consult references [17,18] for an in-depth overview. In [17], a comparison is made between a range of commercial LED driver typologies.…”

This paper highlights the benefits and possible drawbacks of a DC-based lighting infrastructure for powering Light Emitting Diode (LED)-lamps. It also evaluates the efforts needed for integrating the so called smart lighting and other sensor/actuator based control systems, and compares existing and emerging solutions. It reviews and discusses published work in this field with special focus on the intelligent DC-based infrastructure named EDISON that is primarily dedicated to lighting, but is applicable to building automation in general. The EDISON "PowerLAN" consists of a DC-based infrastructure that offers telecommunication abilities and can be applied to lighting retrofitting scenarios for buildings. Its infrastructure allows simple and efficient powering of DC-oriented devices like LED lamps, sensors and microcontrollers, while offering a wired communication channel. This paper motivates the design choices for organizing DC lighting grids and their associated communication possibilities. It also shows how the EDISON based smart lighting solution is evolving today to include new communication technologies and to further integrate other parts of building management solutions through the OneM2M (Machine to Machine) service bus.

“…An unregulated DC voltage is produced without performing any PFC. Such a configuration is only useful for low-power LED applications, of which the PF requirement is less stringent [41], [42]. Also, the SIMO converter in [40] is operating in continuous conduction mode (CCM) and suffers from cross-regulation issues.…”

Abstract-Various AC/DC LED driver topologies have been proposed to meet the challenges of achieving a compact, efficient, low-cost and robust multi-string LED lighting system. These LED drivers typically employ a two-stage topology to realize the functions of AC/DC rectification and independent current control of each LED string. The choice of having two stage conversions involves additional hardware components and a more complicated controller design process. Such two-stage topologies suffer from a higher system cost, increased power loss, and large form factor. In this paper, a single-stage AC/DC single-inductor multiple-output (SIMO) LED driver is proposed. It uses only one single inductor and N+1 active power switches (N being the number of LED strings) with reduced component count and smaller form factor. The proposed driver can achieve both functions of AC/DC rectification with a high power factor and precise independent current control of each individual LED string simultaneously. A prototype of an AC/DC single-inductor triple-output (SITO) LED driver is constructed for verification. Experimental results corroborate that precise and independent current regulation of each individual LED string is achievable with the proposed driver. A power factor of above 0.99 and a peak efficiency of 89% at 30 W rated output power are attainable.
