  Title Why Lighting Claims Might Well Be Wrong Type Journal Article
  Year 2017 Publication International Journal of Sustainable Lighting Abbreviated Journal Intl J of Sustainable Lighting  
  Volume 19 Issue 1 Pages 69-74  
  Keywords Security; Crime; lighting; regulation  
  Abstract This paper gives some background to claims of benefit from road lighting and why large beneficial claims may be suspect. It places this in the context of general concerns about the unreliability of claims in science using knowledge gained, particularly from investigations in the field of health-care. It points to the need to plan, proceed and check science in unbiased and rigorous ways. It gives recommendations for more transparency, asks for clear protocols to be produced in advance, that clear reports are written which follow appropriate reporting guidelines and that the data is accessible.

  Title Contentious Light: An Analytical Framework for Lighting Conflicts Type Journal Article
  Year 2018 Publication International Journal of Sustainable Lighting Abbreviated Journal  
  Volume 20 Issue 1 Pages 62-77  
  Keywords Society; Lighting; Planning  
  Abstract This paper takes into view the broad range of contemporary conflicts regarding outdoor lighting. It proposes a working-definition that allows for differentiating lighting conflicts from other forms of lighting-related contention, as well as an analytical framework that allows for the structured description of individual lighting conflicts, and the comparative analysis of multiple cases. The analytical framework was developed based on the social-scientific analysis of media reports of existing conflict cases in Europe and North America, and informed by existing knowledge from the fields of lighting and conflict studies. A central challenge for developing such a framework is dealing with the high level of contingency and complexity of lighting conflicts. The framework reduces this complexity by focusing its field of vision to those aspects that are directly related to the lighting and its contestation. For each of these aspects, it provides sets of descriptive variables that allow for describing the conflicts’ individuality in a standardized – and thus comparable – way. The framework strictly separates the regarded aspects from their judgment by the conflict parties, making it possible to contrast their views on one and the same lighting situation. A visual template supports the process of analysis. It allows for depicting individual cases in short, and for clearly identifying where perspectives differ. At the multiple-case level, the framework not only opens up possibilities for spatial and temporal comparisons of lighting conflicts and the subsequent development of typologies, but also for harnessing their potential for informing the development of more sustainable planning and policy approaches for artificial lighting.

  Title Energy Efficiency Considerations for LED-based Lighting of Multipurpose Outdoor Environments Type Journal Article
  Year 2015 Publication IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensingournal of Emerging and Selected Topics in Power Electronics Abbreviated Journal IEEE J. Emerging and Sel. Topics in Power Elec.  
  Volume PP Issue 99 Pages 1  
  Keywords Lighting; LED lighting; LED; optimization; lighting technology; lighting design; energy; energy efficiency  
  Abstract Nowadays street lighting accounts for 53% of outdoor lighting use and the market is continuously increasing. In the context of rising energy prices and growing environmental awareness, energy efficiency is becoming one of the most important criteria for street lighting systems design. LED-based lights have become the primary option for replacing conventional light bulbs, being digitally controllable, small, highly efficient, and cheap to manufacture. Advanced control strategies adapted to ambient conditions are needed to combine low energy consumption and high quality light ambience according to changing specifications. This paper describes an outdoor lighting solution aimed at energy efficient performance in the context of multipurpose outdoor environments, where control is crucial in achieving efficiency improvements. The work addresses efficiency at the component level, by optimizing the performance of LED drivers, and at system level, defining the control strategy and associated hardware infrastructure. The approach designed was tested in a real environment. The performance of the lighting installation was assessed using the web-based monitoring application, providing real-time consumption information and aggregated historical data.

  Title Research on the Lighting Performance of LED Street Lights With Different Color Temperatures Type Journal Article
  Year 2015 Publication IEEE Photonics Journal Abbreviated Journal IEEE Photonics J.  
  Volume 7 Issue 6 Pages 1-9  
  Keywords Lighting; LED; light-emitting diodes; PC-LED; dark adaption; color perception; fog; skyglow  
  Abstract While light-emitting diodes (LEDs) are a very efficient lighting option, whether phosphor-coated LEDs (PC-LEDs) are suitable for street lighting remains to be tested. Correlated color temperature (CCT), mesopic vision illuminance, dark adaption, color perception, fog penetration, and skyglow pollution are important factors that determine alight's suitability for street lighting. In this paper, we have closely examined the lighting performance of LED street lights with different color temperatures and found that low-color-temperature (around 3000 K) PC-LEDs are more suitable for street lighting.

  Title Does ambient light at night reduce total melatonin production? Type Journal Article
  Year 2015 Publication Hormones Abbreviated Journal Hormones  
  Volume Issue Pages  
  Keywords Human Health; melatonin; ambient lighting; indoor light; sleep; *Circadian Rhythm; chronotype  
  Abstract It was with great interest that we read the recent study by Hersh et al on the effects of sleep and light at night on melatonin in adolescents. Of particular interest was their focus on electronic use after “lights out”. The authors highlight the importance of understanding what effects this may have on sleep, citing a survey that showed that 72% of American 13-18 year olds regularly use a cellphone or computer before trying to go to sleep. In their study, Hersh et al1 did not observe a significant suppression in urinary morning melatonin (aMT6s) levels with respect to the use of electronic devices between lights off and sleep onset. Therefore, the authors conclude that “nighttime behaviors of adolescents by and large do not impact urinary melatonin levels”. Absence of evidence, however, is not the same as evidence of absence, and we believe that the authors’ conclusion is premature.
