“…Street lighting is a high energy-consuming facility that requires long-term lighting, which is a burden to environmental protection, Sustainability 2023, 15, 10579 2 of 19 electricity consumption and government finance. In line with the global trend of clean energy, energy saving and carbon reduction, as well as reducing the financial burden of the government, street lighting, as an important type of urban lighting, can meet the demand of environmental protection by using energy-saving and efficient light sources [3][4][5][6]. Advantages of light-emitting diodes (LEDs) over high-pressure mercury lamps are their long life, high energy efficiency, low installation and maintenance costs, and the absence of toxic chemicals such as mercury, which contributes to environmental protection and sustainable development.…”

The use of light-emitting diodes (LEDs) in street lighting applications has been greatly welcomed with the current trends of energy saving, environmental protection, carbon reduction, and sustainable development. This paper presents a novel AC-DC LED integrated streetlight driver that combines an interleaved buck converter with a coupled inductor and a half-bridge series resonant converter with a full-bridge rectifier into a single-stage power conversion topology with power factor correction (PFC) and soft switching capabilities. The PFC is achieved by designing the coupling inductor in the interleaved buck converter sub-circuit in discontinuous conduction mode. In addition, the resonant tank in the half-bridge series resonant converter sub-circuit is designed to be similar to an inductive load, thus giving the power switch a zero-voltage switching (ZVS) function, decreasing switching losses and increasing the overall efficiency of the proposed circuit. A prototype circuit of the proposed LED integrated streetlight driver with a power rating of 165 W (235 V/0.7 A) and 110 V input utility voltage has been developed and tested. According to the measurement results, a power factor greater than 0.98, a total harmonic distortion coefficient of the input current less than 3%, and an efficiency greater than 89% were obtained in the AC-DC LED integrated streetlight driver. Therefore, the experimental results are satisfactory and demonstrate the functionality of the proposed AC-DC LED integrated streetlight driver.

“…As well, the costs of installing and maintaining LED streetlights have virtually bottomed out. Consequently, LED streetlights have replaced traditional sources of street lighting and play an important role in energy-efficient outdoor lighting [5][6][7][8][9][10]. Replacing old energy-consuming traditional streetlight sources with energy-efficient LED lights not only reduces the environmental pollution caused by high-pressure mercury lamps and carbon dioxide emissions, but also significantly reduces the power consumption of streetlights and lowers the power generation load and costs for power companies.…”

A Novel Light-Emitting Diode Streetlight Driver Circuit Applied to a Direct Current-Input Voltage Source

et al. 2023

With the global advocacy of green lighting and the urgent need for energy saving and carbon reduction, more and more street lighting applications have entered the era of being replaced by light-emitting diode (LED) lighting sources. This paper presents a new LED streetlight driving circuit applied to a direct current (DC)-input voltage source, which consists of a buck converter combined with a flyback converter to reduce the number of circuit components required and to recover the leakage energy of the transformer to improve energy conversion efficiency. In addition, this study also completed the analysis of the operational principle of the new LED streetlight driving circuit, and developed a prototype LED streetlight driver with DC-input voltage of 48V and output power of 72 W (36 V/2 A). Finally, the measurement results of the prototype circuit show that the output voltage ripple rate was less than 15%, the output current ripple rate was less than 6%, and the circuit efficiency was as high as 91%.
