Abstract |
The study examines the spatial trend of light pollution across the study area. The Global Positioning System (GPS) was used to acquire the coordinates of each respondent resident, where structured questionnaire were administered in the study area and then imported to the ArcGIS 9.3 software environment to analyse the spatial trend in light pollution using the Inverse Distance Weighted (IDW) method of interpolation. Findings, reveals that the perception of pollution by light stray is obviously noticed by the respondents with particular emphasis on light stray from traffic light, neighbor security lights which to a large extend alters their level of comfort and distort their level of outdoor relaxation. Thus, the study recommends, among others, that: shielded light bulbs or properly designed light fittings should be installed to avoid light rays spreading beyond the needed boundaries. And measure should be taken to ensure car drivers use properly fixed headlamps that are not damaged and also, awareness should be passed on adequate use of headlamps by road users (vehicle drivers) on streets when compared with use on highways and minor roads. |

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 |

Abstract |
In this work, we investigated 39 façade lighting displays, all of which consisted of tri-chromatic light sources, namely blue-, green-, and red- light units, in Shenzhen, China. We extracted the spectral characteristics of the mean peak wavelength/full-width at half-maximum,and proposed universal spectral models. We further established the ‘chromaticity-performance’ relation to quantitatively assess the impact of light pollution on typical species based on corresponding action spectra. The findings provide a low-cost, fast and precise approach to assess light pollution of complicated light environment, and may help reduce energy waste and adverse environmental consequences associated with light pollution. |

Abstract |
This paper proposes a new design method to create a novel optical element to generate uniform illumination within a rectangular area. Based on this model, an illuminated area is irradiated by two sets of rays; the first one irradiates the target plane after refraction from the top section of the lens, and the second one irradiates from the reflection at the side profile of the lens and then from refraction at the top part of the lens. The results show that a uniformity of over 90% can be achieved. |

Abstract |
Visible light is all around us, from sunlight to street lighting and automobile headlights to the backlight on a smartphone and in nearly every indoor space. Humans are so accustomed to working and living in artificial light that many of us have not stopped to consider the implications. Most OSH professionals’ experience with light and artificial lighting is likely limited to assessing whether sufficient light exists for people to see where they are going or carry out a task, or whether a light is too bright. This article aims to provide a current review of lighting for OSH professionals. Such a review is timely due to emerging issues including energy efficiency, human health impacts (e.g., blue light hazard, circadian rhythm disruption, fatigue), human performance (e.g., visual performance, visual comfort) and environmental impacts (e.g., light pollution). |
