  Title Concept of Intelligent Solid-State Street Lighting Technology Type Journal Article
  Year 2012 Publication Electronics and Electrical Engineering Abbreviated Journal ElAEE  
  Volume 18 Issue 10 Pages (up)  
  Keywords outdoor lighting; street lighting; LED; LED lighting; energy consumption; algorithm design and analysis; electromagnetic interference  
  Abstract Street and road lighting consumes about ~2 % of global electric power and the trade-off between energy saving and social needs for traffic safety, crime prevention, aesthetic comfort, etc. has to be established. A wide range investigation of an intelligent solid-state street lighting system prototype equipped with LED-based luminaires, motion sensors and microcontrollers with power-line-communication interfaces was performed under real outdoor conditions. The two-level and two-zone street illumination method was implemented basing on psychophysical investigation. The decrease of efficiency under the dimming conditions and significant electromagnetic interference in the frequency range of tens and hundreds MHz were identified as limiting factors of conventional current regulating ICs and the necessity of further improvement was pointed out.

  Title Gazing Up: An Exploration of Municipal Night Lighting Practices Amongst Six Canadian Municipalities Type Manuscript
  Year 2014 Publication Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords light pollution; public policy; Canada; outdoor lighting; municipal  
  Abstract Light pollution is broadly defined as the unnecessary illumination of the nocturnal environment. Light pollution is a pervasive phenomena shown to have harmful consequences for both the biotic and abiotic components of an ecosystem. While some municipalities have begun to address the environmental and economic costs of light pollution, most have not. The goal of this study was to investigate current municipal night lighting practices for six selected Canadian municipalities with the aim of determining their policies and practices for night lighting. Semi-structured interviews with key informants were conducted and analyzed using a mixed methods approach that included a thorough literature review. The results indicate that rising energy costs, aging infrastructure and the lighting industry are driving the majority of changes taking place in adapting municipalities while most municipalities remain content with status quo. The research conducted led to guideline improvements for municipal night lighting in today’s municipalities.

  Title The Night Shift: Lighting and Nocturnal Strepsirrhine Care in Zoos Type Book Whole
  Year 2013 Publication Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords zoos; light at night; circadian disruption; strepsirrhines; primates; lorises; pottos; lighting design  
  Abstract Over billions of years of evolution, light from the sun, moon, and stars has provided

organisms with reliable information about the passage of time. Photic cues entrain

the circadian system, allowing animals to perform behaviors critical for survival and

reproduction at optimal times. Modern artificial lighting has drastically altered

environmental light cues. Evidence is accumulating that exposure to light at night

(particularly blue wavelengths) from computer screens, urban light pollution, or as

an occupational hazard of night-shift work has major implications for human health.

Nocturnal animals are the shift workers of zoos; they are generally housed on

reversed light cycles so that daytime visitors can observe their active behaviors. As a

result, they are exposed to artificial light throughout their subjective night. The goal

of this investigation was to examine critically the care of nocturnal strepsirrhine

primates in North American zoos, focusing on lorises (Loris and Nycticebus spp.) and pottos (Perodicticus potto). The general hypothesis was that exhibit lighting design affects activity patterns and circadian physiology in nocturnal strepsirrhines. The

first specific aim was to assess the status of these populations. A multi-institutional husbandry survey revealed little consensus among zoos in lighting design, with both red and blue light commonly used for nocturnal illumination. A review of medical records also revealed high rates of neonate mortality. The second aim was to

develop methods for measuring the effects of exhibit lighting on behavior and

health. The use of actigraphy for automated activity monitoring was explored.

Methods were also developed for measuring salivary melatonin and cortisol as

indicators of circadian disruption. Finally, a multi-institutional study was conducted

comparing behavioral and endocrine responses to red and blue dark phase lighting.

These results showed greater activity levels in strepsirrhines housed under red light than blue. Salivary melatonin concentrations in pottos suggested that blue light

suppressed nocturnal melatonin production at higher intensities, but evidence for

circadian disruption was equivocal. These results add to the growing body of

evidence on the detrimental effects of blue light at night and are a step towards

empirical recommendations for nocturnal lighting design in zoos.

  Title A Win-Win-Win for Municipal Street Lighting: Converting Two-Thirds of Vermont's Street Lights to LED by 2014. Type Journal Article
  Year 2012 Publication American Council for an Energy-Efficient Economy. Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords Lighting Systems  
  Abstract Reducing energy costs and enhancing the nighttime environment with LED street lighting

is by now well understood. However, few municipalities and utilities have successfully taken

advantage of this opportunity to convert their street lighting operations to LEDs. Before a

system-wide conversion of existing street lights can occur, a utility must obtain the large amount

of required capital, identify appropriate LED street light equipment for their applications,

consider changes in utility rate structures, and design effective methods for recovering costs.

Using Vermont as a case study, this paper presents a partnership model among the statewide

energy efficiency utility, the state’s largest electric utilities, and several municipalities. The

model was designed to overcome the challenges to widespread LED street light conversion. By

2014, more than two-thirds of Vermont’s municipal street lights will be upgraded to LED

technology. The conversion will: (1) provide municipalities with better nighttime street lighting

and significant cost savings—at no additional capital expense to the municipalities, (2) deliver

8,000 MWh of cost-effective new savings to the energy efficiency utility, and (3) deliver

financially attractive returns for Vermont’s utilities. This win-win-win model is scalable and

replicable, and is now being considered in Massachusetts and Rhode Island
