  Title (up) A preliminary investigation of Luojia-1 night-time light imagery Type Journal Article
  Year 2019 Publication Remote Sensing Letters Abbreviated Journal Remote Sensing Letters  
  Volume 10 Issue 6 Pages 526-535  
  Keywords Remote Sensing; Instrumentation  
  Abstract Launched on 2 June 2018, Luojia-1 satellite records night-time light imagery at 130 m resolution, which is higher than most of the existing night-time light images to date. This study evaluated radiometric and spatial properties of the Luojia-1 satellite imagery for cities of Los Angeles, Wuhan and Rome as well as the change detection capability for Zunyi city. For the radiometric property, the analysis shows that the Luojia-1 images correlate well with the radiance of the Visible Infrared Imaging Radiometer Suite (VIIRS)’s Day and Night Band (DNB), and that the Luojia-1 images have a wider range of radiance values, as well as higher radiance values (e.g., 40%–90% higher) than the VIIRS DNB images. Using wavelet decomposition and change detection analysis to evaluate spatial property and change detection capability, it was found that the Luojia-1 images provide abundant spatial detail information, with about 20%–54% energy of wavelet component of the images stored in 100–400 m resolutions, and they can help to track the electrification of new roads and buildings at a fine resolution. This study shows that the Luojia-1 images are an effective data source for analysing spatiotemporal distribution of night-time light and its associated socioeconomic attributes.

  Title (up) A Research on Visual Performance at Different Ages Depending on Color Temperature of Headlights Type Journal Article
  Year 2017 Publication Journal of the Korean Institute of Illuminating and Electrical Installation Engineers Abbreviated Journal  
  Volume 31 Issue 8 Pages 40-48  
  Keywords Lighting  
  Abstract Under night-time driving conditions, both cones and rods in eye’s retina simultaneously act to influence mesopic vision in two areas: central and peripheral visions. However, as people age, the amount of light received as well as the color temperature perceived by the human eyes also change. This research, through simulations and scaled down experiments with various headlight color temperatures and two levels of fixed brightness, deals with differences in ability to detect and identify obstacles by the subjects in their 20’s and 50’s.

According to the results obtained from the experiments on peripheral vision, subjects in their 20’s detected the obstacles more quickly at the combined color temperature of 3,000K+4,500K than at the single color temperature of 4,500K, and likewise at 3,000K+5,500K than at 5,500K; this tendency was significantly more noticeable for the subjects in their 50’s. As for the central vision, the results showed that there were no significant differences due to color temperature between the subjects in their 20’s and those in their 50’s. Moreover, the landolt ring experiment conducted under low luminance yielded higher percentage of correct answers at combined color temperatures.

  Title (up) A review of energy efficiency label of street lighting systems Type Journal Article
  Year 2016 Publication Energy Efficiency Abbreviated Journal Energy Efficiency  
  Volume Issue Pages 1-18  
  Keywords Energy; Energy Efficiency Index; Total Luminous Flux; Energy Efficiency Label; Electronic Ballast; Energy Performance Indicator; Lighting Project; Energy Efficiency Class; Energy Efficiency Level; Road Lighting; Active PowerLighting System; Wind Turbine; Current Energy Efficiency; Luminous Efficacy; Electricity Consumption; Kiviat diagram; Lamp; Light pollution; Pie chart; Dimming luminous flux; review  
  Abstract There are very few countries that have provisions addressing the energy efficiency of the whole street lighting system, such as Spain or the Netherlands. Nevertheless, there is not an agreement about how energy efficiency must be assessed. The Spanish Government contemplates it in the Royal Decree 1890/2008 with the goal of improving energy savings and efficiency. However, this has not obtained the expected results. Nowadays, energy efficiency of this kind of systems is assessed using a label. In the case of Spain, this label only assesses one magnitude. The contributions of this paper are two evaluation systems (kiviat diagram and pie chart) which assess five magnitudes: lamps, energy efficiency index, light pollution, renewable energy contribution, and harness of the luminous flux using dimming. After that, a survey was done to study several subjects: (1) if citizens are aware about the efficiency of street lighting systems, (2) whether the sample of colors used in the label is adequate, and (3) if our proposed systems could replace the current evaluation system. Finally, the paper finishes with the conclusions of the survey.

  Title (up) A review of local authority road lighting initiatives aimed at reducing costs, carbon emissions and light pollution Type Journal Article
  Year 2011 Publication Report to Defra, UK Abbreviated Journal  
  Volume Issue Pages  
  Keywords Economics  
  Abstract This review of local authority road lighting initiatives was commissioned by Defra’s

Statutory Nuisance team in response to one of the recommendations contained in the

Royal Commission on Environmental Pollution’s (RCEP) report “Artificial Light in the

Environment”. The RCEP report made reference to road lighting trials being undertaken by

local authorities in the UK that have been reducing or turning road lights off. This report

has been produced following a review of fifteen out of twenty five such initiatives identified

in England and Wales.

The overall aim of the review was to examine the local authority road lighting trials and

initiatives and draw out the lessons learnt.

Local authorities have implemented these initiatives in response to economic pressures

such as rising energy prices and environmental concerns about wasted energy and the

effects of carbon emissions and light pollution. Changes have been made to the way they

deliver public road lighting services by:

 switching selected road lights off;

 lighting roads for part of the night only;

 dimming the level of lighting during the early hours of the morning;

 reducing the “burning” time of lamps in the evening and early morning; and / or

 using new and evolving technologies such as a central management system (CMS) or

light emitting diodes (LED).

These initiatives have the potential to provide a range of benefits including substantial

financial savings to local authorities, reduced carbon emissions and reduced light pollution.

However, the benefits need to be considered in the context of the important role that road

lighting plays in terms of assisting traffic safety and helping to reduce crime. Local

authorities have needed to carefully consider the impacts of proposed changes on these

issues and adopt appropriate management strategies prior to, during and post

implementation. These strategies have included the use of measures such as exemption

criteria, risk assessments and active engagement with stakeholders.

From this review, it is evident that there are a range of options and tools available to local

authorities as they consider how best to respond to the growing economic and

environmental pressures on the way they deliver their public road lighting services.

It is hoped that the information contained within this report may inform local authorities

which face similar challenges in the future, in identifying some of the key issues that may

affect their particular public road lighting service and assist in the process of implementing

changes appropriate to their circumstances.
