  Title (up) A study on selecting of Light Cutoff Panel depending on the installation condition using the lighting simulation Type Journal Article
  Year 2016 Publication Journal of the Korea Academia-Industrial cooperation Society Abbreviated Journal Journal of the Korea Academia-Industrial cooperation Society  
  Volume 17 Issue 2 Pages 246-251  
  Keywords Lighting; Light cutoff panel; Light pollution; Light trespass; Relux; Security light  
  Abstract The use of security lighting that emits spill light is considered a cause of light trespass problems in the residential areas. Therefore, a cutoff panel was installed as an alternative way to reduce light trespass. On the other hand, it has another problem in that it is less effective and is not good enough for aesthetics and safety. In this study, a light cutoff panel was designed and manufactured to reduce the light trespass, and the structure of a proper light cutoff panel was studied. Using a goniophotometer, the light distribution file (IES file) was extracted and the characteristics of light distribution were analyzed using the RELUX program. The results showed that the reduction of spilt light in the backward direction was decreased significantly for all types of light cutoff panels except the coated globe. In the case of a black powder coated light cutoff panel, the forward light caused by light reflected from the surface of the light cutoff panel was also reduced, which means that the black powder coated light cutoff panel is effective in the performance of light cutoff in the forward and backward directions. In addition, the coated glove increased the spilt light in the forward and backward directions because it reflects the upward light to go down. A 90 % accuracy between the measurement value of light trespass and the expected value of the light trespass was obtained from a simulation.

  Title (up) A survey of the luminance distribution in the nocturnal environment in Shanghai urban areas and the control of luminance of floodlit buildings Type Journal Article
  Year 2006 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume 38 Issue 3 Pages 185-189  
  Keywords Lighting  
  Abstract A survey of the luminance distribution of the nocturnal environment in Shanghai urban areas, which included 11 locations and 16 buildings, was made. The 11 locations could be categorized as commercial, administration, leisure or residential. The average environmental luminance of these was recorded. The authors identified the effects of excessive exterior lighting. The luminance was measured and subjective appraisals made of 16 buildings. The writers have developed an empirical formula for arriving at the brightness level rating for floodlit buildings and recommended corresponding working ranges of luminance.

  Title (up) 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  
  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

  Title (up) Adaptive light: a lighting control method aligned with dark adaptation of human vision Type Journal Article
  Year 2020 Publication Scientific Reports Abbreviated Journal Sci Rep  
  Volume 10 Issue 1 Pages 11204  
  Keywords Human Health; Vision; Lighting  
  Abstract Light exposure before sleep causes a reduction in the quality and duration of sleep. In order to reduce these detrimental effects of light exposure, it is important to dim the light. However, dimming the light often causes inconvenience and can lower the quality of life (QOL). We therefore aimed to develop a lighting control method for use before going to bed, in which the illuminance of lights can be ramped down with less of a subjective feeling of changes in illuminance. We performed seven experiments in a double-blind, randomized crossover design. In each experiment, we compared two lighting conditions. We examined constant illuminance, linear dimming, and three monophasic and three biphasic exponential dimming, to explore the fast and slow increases in visibility that reflect the dark adaptation of cone and rod photoreceptors in the retina, respectively. Finally, we developed a biphasic exponential dimming method termed Adaptive Light 1.0. Adaptive Light 1.0 significantly prevented the misidentification seen in constant light and effectively suppressed perceptions of the illuminance change. This novel lighting method will help to develop new intelligent lighting instruments that reduce the negative effect of light on sleep and also lower energy consumption.
