  Title Changing the colour of night on urban streets – LED vs. part-night lighting system Type Journal Article
  Year 2019 Publication Socio-Economic Planning Sciences Abbreviated Journal Socio-Economic Planning Sciences  
  Volume in press Issue Pages 100692  
  Keywords (up) Energy; Planning; Economics; United Kingdom; LED; Lighting  
  Abstract Many cities in the United Kingdom are upgrading the streetlights to white light-emitting diode (LED) lamps for reducing the electricity costs and attaining the sustainable energy solutions. Installation of LED lamps on urban street requires higher installation costs and a long-term period to payback benefits of replacing outdated streetlights in terms of energy savings and costs. To achieve the short-term energy efficiency of urban street lighting, city councils sometimes adopt the part-night lighting system particularly in the residential areas. The Coventry City Council recently replaced 29,701 existing sodium lights with LED lamps. This paper performs the economic analyses to understand the feasibility of two street lighting systems: LED lamps and ‘part-night’ lightings on the Coventry streets during the twenty-year period assuming the return period of investment is twenty years. The projection of energy consumption and costs for LED lamps and part-night lighting systems shows that electricity can be saved by 44% and 21% comparing to current electricity usages, respectively. Considering the budgetary constraints of Coventry City Council, this paper concludes that the part-night lighting system may be beneficial in short-term period, but it is economically feasible to replace the existing lower efficiency lights with LED lamps.

  Title Energy Efficiency Lighting – Romania Type Journal Article
  Year 2015 Publication Romanian Journal of Building Services Abbreviated Journal Romanian J. of Building Services  
  Volume 1 Issue 3 Pages 1-7  
  Keywords (up) Energy; Romania; architecture; sustainability; sustainable lighting  
  Abstract The paper presents the Romanian experience, which is unique in promoting green

buildings and the impact for lighting. Without prior experience, situation has changed with the new Romanian Green Building Council, founded in 2008, which started with courses on sustainability (including 8 hours course on lighting), with green building contest and ending with a European web-platform Construction21.eu. A major breakthrough was a 2012 Cluj-Napoca city council decision that a certified green building should receive a 50% local tax reduction.

Since then all new buildings are LEED or BREEAM certified and lighting was one of the parts were buildings received a lot of points or credits. The sustainable lighting approach is the future oriented solution. It includes all the aspects not

only technical or energy efficient ones and for this we need to rethink lighting from a broader perspective.

  Title Individual factors influencing the assessment of the outdoor lighting of an urban footpath Type Journal Article
  Year 2011 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology  
  Volume 43 Issue 1 Pages 31-43  
  Keywords (up) footpath lighting; pathway lighting; outdoor lighting; lighting perception  
  Abstract During the hours of darkness, the mobility of young women, the elderly and the disabled is limited in urban areas. In a field study possible predictors of the perceived visual accessibility and the perceived danger of an urban footpath were investigated. Eighty-one people individually walked along the footpath after dark. They subjectively assessed the environment and answered a questionnaire about personality and socio-demographics. Visual accessibility was predicted by visual field, environmental trust and brightness. Danger was predicted by the pleasantness of the lighting, gender, brightness and environmental trust. Consequently, the influence of individual characteristics, including the subjective judgments of brightness and hedonic tone and the personality dimension of trust in the physical environment, should be considered in the design of exterior lighting for urban footpaths.

  Title Historical perspective on the physics of artificial lighting Type Journal Article
  Year 2018 Publication Comptes Rendus Physique Abbreviated Journal Comptes Rendus Physique  
  Volume 19 Issue 3 Pages 89-112  
  Keywords (up) History; Lighting  
  Abstract We describe the evolution of lighting technologies used throughout the ages, and how the need for improvements was such that any new technology giving better and cheaper lighting was immediately implemented. Thus, every revolution in energy sources – gas, petrol electricity – was first put to large-scale use in lighting. We describe in some detail several “ancient” techniques of scientific interest, along with their physical limitations. Electroluminescence – the phenomenon by which LEDs directly convert electricity into light – was long thought to only be of use for indicators or flat panel displays supposed to replace the bulky cathode-ray tubes. The more recent uses of LEDs were mainly for street traffic lights, car indicators, small phone displays, followed by backlighting of TV screens. LED lamps for general lighting only emerged recently as the dominant application of LEDs thanks to dramatic decrease in cost, and continuous improvements of color quality and energy conversion efficiency.
