  Title A New Light Control Method with Charge Induction of Moving Target Type Journal Article
  Year 2019 Publication IEEE Sensors Journal Abbreviated Journal (up)  
  Volume 19 Issue 16 Pages  
  Keywords Lighting; Instrumentation  
  Abstract Intelligent lamp control system has been widely studied all over the world because of its energy saving and social effect. In this paper, a new intelligent lamp control method based on charge induction for moving target is proposed. The detection model is established with the surface charge induction and verified by a luggage detection experiment. The intelligent lamp control system using the detection method is carried out. The performance of the system demonstrates that the proposed method can detect the moving target at any orientation whatever with or without occlusion and the detection distance can reach more than 3 m for the pedestrian.

  Title Assessment of Light Pollution Based on the Analysis of Luminous Flux Distribution in Sports Facilities Type Journal Article
  Year 2019 Publication Engineer of the XXI Century Abbreviated Journal (up)  
  Volume 70 Issue Pages 139-150  
  Keywords Lighting  
  Abstract The article attempts to assess the amount of light pollution with artificial light from sports facilities. The football stadium has been analysed, while considering a few configurations that take into account different coefficients of reflection of the luminous flux for the tribunes and the object main board. Simplified model of the football stadium was introduced to the DIALux simulation software, and then computer calculations were made for selected variants. In addition, the applicable normative requirements in the field of lighting systems were discussed and the mathematical distribution of the luminous flux in the examined sports facility was presented.

  Title Lighting and Power Upgrade Recommendations for U.S. National Park Service Caribbean Units Type Journal Article
  Year 2019 Publication National Park Service Caribbean Units Abbreviated Journal (up)  
  Volume Issue Pages  
  Keywords Lighting; Conservation; Ecology; Skyglow; Planning  
  Abstract The U.S. National Park Service (NPS) maintains and operates numerous park units along the Eastern Seaboard of the United States, extending into the Caribbean to Commonwealth territories like Puerto Rico and the U.S. Virgin Islands (USVI). Several of these units were in the direct path of hurricanes Irma and Maria during the 2017 hurricane season and suffered considerable damage, including power outages, structural damage, and destroyed equipment. In February 2018, a task force deployed to three locations in the Caribbean to assess hurricane damage to the existing lighting systems and energy infrastructure. The primary objective was providing related recommendations for resiliency upgrades to the lighting and electrical supply systems, with special added emphasis on the numerous goals, objectives, and requirements of the NPS (such as protecting night skies, wildlife, wilderness character, cultural resources, etc.). Numerous opportunities exist for simultaneously increasing resiliency and preserving natural environments within these sensitive locations, and technological approaches that work in the extreme conditions encountered here should readily translate to many other less complex sites across the greater park system. Ultimately, care and attention to detail in implementation are the most important underlying requirements for success across the myriad needs likely encountered at these sites, once commitment to resolving them has been secured

  Title Economic feasibility of energy efficiency improvements in street lighting systems in Rome Type Journal Article
  Year 2017 Publication International Journal of Energy Economics and Policy Abbreviated Journal (up)  
  Volume 7 Issue 1 Pages 190-198  
  Keywords Economics; Energy; Society; LED lighting; LED; real options  
  Abstract This study evaluates an investment project concerning the redevelopment of the public lighting of the Municipality of Rome. In particular, we consider the replacing of the traditional lamps of the system with LED lamps. We consider the factors that affect this kind of project: the cost of energy, the manteinance cost, the investment cost and the Weighted Average Cost of Capital (WACC). Our results underline the reduction of energy consumption and of the maintenance costs, lower emissions of CO2 into the atmosphere, the reduction of light pollution, the positive effects on road safety and the indipendence by incentives.

  Title Responses of insectivorous bats and nocturnal insects to local changes in street light technology Type Journal Article
  Year 2019 Publication Austral Ecology Abbreviated Journal (up)  
  Volume 44 Issue 6 Pages 1052-1064  
  Keywords Animals; Mammals; Bats; Chalinolobus gouldii; Miniopterus schreibersii oceanensis; Australia; LED; lighting; street lighting  
  Abstract Artificial light at night is a pervasive anthropogenic stressor for biodiversity. Many fast‐flying insectivorous bat species feed on insects that are attracted to light‐emitting ultraviolet radiation (10–400 nm). Several countries are currently focused on replacing mercury vapour lamps, which emit ultraviolet light, with more cost‐efficient light‐emitting diode (LED) lights, which emit less ultraviolet radiation. This reduction in ultraviolet light may cause declines in insect densities in cities, predatory fast‐flying bats, and some edge‐foraging and slow‐flying bats. Capitalising on a scheme to update streetlights from high ultraviolet mercury vapour to low ultraviolet LED in Sydney, Australia, we measured the activity of individual bat species, the activity of different functional groups and the bat and insect communities, before and after the change in technology. We also surveyed sites with already LED lights, sites with mercury vapour lights and unlit bushland remnants. Species adapted to foraging in cluttered vegetation, and some edge‐space foraging species, were more active in unlit bushland sites than in all lit sites and decreased in activity at lit sites after the change to LED lights. The change to LED streetlights caused a decrease in the fast‐flying Chalinolobus gouldii but not Miniopterus schreibersii oceanensis, the latter being more influenced by seasonal and environmental variables. Insect biomass was not affected by changing light types, but instead was negatively correlated with the moon's percentage illuminance. Changing streetlights to LEDs could result in a decline in some insectivorous bats in cities. This study confirms that unlit urban bushland remnants are important refuges for high bat diversity, particularly for more clutter‐adapted species and some edge‐space foraging species. Preventing light penetration into unlit bushland patches and corridors remains essential to protect the urban bat community.
