“…A study performed by the European Commission has shown that between 30% and 50% of electricity used for lighting could be saved by investing in energy-efficient lighting systems [18]. In Spain, in some municipalities, the consumption of energy in public lighting reaches up to 80% of the total electricity consumption.…”

This paper analyzes the technical and economic viability and sustainability of urban street lighting installation projects using equipment powered by photovoltaic (PV) energy. First, a description of the state-of-the-art of the technology is performed, studying the components involved in solar LED luminaires for street lighting application and examples of autonomous PV systems installed in different countries. Later, a case study a based on a renovation project of the street lighting installation at a 5000-inhabitant municipality in Lanzarote (Spain) is presented. Two alternatives are analyzed: underground channeling of the previous aerial electrical grid and the installation of LED luminaires, and, on the other hand, the installation of autonomous LED solar luminaires. Simulations concluded that a PV lighting installation proposal guarantees the existing M3 lighting requirements (EN 13201-2:2015) and represents a saving in the material execution budget of 43.78% with respect to the channeled power grid option. Finally, a statistical study has been carried out to assess the social acceptance of Spanish citizens of this autonomous PV technology in urban environments. This considers strengths and weakness of the technology: sustainability, robustness, visual impact, or risk of vandalism. In general, most subjects of all age segments are aware of the problem that means having aerial wiring running at facades (95%) and considers the use of PV in urban lighting sustainable (88%). However, 47% of those surveyed consider that shutdowns due to lack of energy harvesting is problematic and 17% consider this very problematic. This major drawback (visual impact of PV equipment is mostly evaluated as neutral) gives rise to social reluctance, especially in people younger than 50 who remarked this as more problematic than senior segments. Thus, guaranteed operational service is fundamental to have social agreement for PV technology implementation.

A Model to Improve the Implementation Standards of Street Lighting Based on Solar Energy: A Case Study

This paper aims to improve the implementation standards of solar-energy-based street lighting in Indonesia. A model framework was developed to assess existing conditions regarding the level of lux, the distance between poles, pole height, and lamp power. According to the evaluation of the existing circumstances, the street lighting system is not satisfactory according to the national standard, with 64.7% black area. An alternative installation of street lighting designed by DIALux application was proposed to fulfill the technical standard of street lighting. The result shows that this alternative design can be used for renewing existing street lighting with better performance and reliability. Economic analysis of all technically feasible alternatives was conducted afterward by benefit–cost analysis. The analysis shows that solar-energy-based street lighting requires as much as 621,473,620.00 Indonesian Rupiah (IDR), with 1.06 benefit–cost ratios and a 9% reduction of total cost. Therefore, the analysis indicates that solar-energy-based technology can be feasibly implemented in a street lighting system. The results show that the proposed model can be applied to improve the implementation standard of solar-energy-based street lighting.

“…Measures, such as installing additional security lighting or increasing the luminous flux of existing security lighting, can be considered to solve such problems. However, maintaining bright security lighting throughout the night consumes considerable lighting energy and results in light trespass to nearby residents, which can cause sleeping disorders and privacy infringement [6][7][8]. These issues can be solved by providing brighter light only at those locations and times in which a bright luminous environment is needed.…”

Design of a Connected Security Lighting System for Pedestrian Safety in Smart Cities

et al. 2019

Historical and ongoing pedestrian anxiety about night crimes in alleyways is an important issue in our society. Therefore, recommended illuminance levels in pedestrian alleys have been established and security lighting meeting such illuminance levels has been installed to ensure proper brightness. However, pedestrians may still feel that such areas are too dark and want to ensure their safety through sufficient brightness, especially late at night. In this study, a smart security lighting system, which was namely the Connected Security Lighting System (CSLS), has been designed to reduce the pedestrians’ fear of crime in smart cities. The CSLS increases the brightness of security lighting by turning on additional lights to relax pedestrians’ psychological fear of crime because of the increased sense of surveillance. Such a change may also deter potential offenders. The CSLS employs various sensors and information communication technologies that are widely used in interior and outdoor smart lighting applications. It also uses a beacon device and smartphone application to effectively detect pedestrians while infrared sensors in the CSLS are activated to detect any pedestrians approaching from the opposite direction after the beacon device is initiated. The method for controlling the CSLS is described and a prototype system is presented to demonstrate the feasibility of this security lighting system in smart cities.
