  Title Model Calibration Methodology to Assess the Actual Lighting Conditions of a Road Infrastructure Type Journal Article
  Year 2020 Publication Infrastructures Abbreviated Journal Infrastructures  
  Volume (up) 5 Issue 1 Pages 2  
  Keywords Lighting  
  Abstract Street lighting plays an important role in the comfort and safety of drivers and pedestrians, so the control and management of the lighting systems operation and consumption is an essential service for a city. In this document, a methodology is presented to calibrate lighting models in order to assess the lighting performance through simulation techniques. The objective of this calibration is to identify the maintenance factor of the street lamps, determine the real average luminance coefficient of the road pavement and adapt the reflection properties of the road material. The method is applied in three stages and is based on the use of Radiance and GenOpt software suits for the modeling, simulation, and calibration of lighting scenes. The proposed methodology achieves errors as low as 13% for the calculation of illuminance and luminance, evincing its potential to assess the actual lighting conditions of a road.

  Title Firelight LED Source: Toward a Balanced Approach to the Performance of Solid-State Lighting for Outdoor Environments Type Journal Article
  Year 2014 Publication IEEE Photonics Journal Abbreviated Journal IEEE Photonics J.  
  Volume (up) 6 Issue 3 Pages 1-16  
  Keywords LED; lighting; lighting technology; light emitting diode; firelight LED  
  Abstract We report on a blue-amber (“firelight”) cluster of light-emitting diodes (LEDs) with extra-low correlated color temperature (~1860 K) optimized for outdoor lighting under mesopic conditions. When compared with common white LEDs, the firelight LED cluster shows considerably reduced indexes of melatonin suppression and skyglow, increased retinal illuminance for elderly people, but a reduced performance of perceiving colors, which, however, can be tolerated at mesopic luminance. In comparison with an almost metameric high-pressure sodium lamp, the cluster exhibits a potentially higher luminous efficacy, similar reaction time and detection threshold of luminance contrasts for achromatic targets, and noticeably improved color discrimination characteristics.

  Title Solar street lighting: a key technology en route to sustainability: Solar street lighting technology for sustainability Type Journal Article
  Year 2016 Publication Wiley Interdisciplinary Reviews: Energy and Environment Abbreviated Journal WIREs Energy Environ  
  Volume (up) 6 Issue 2 Pages in press  
  Keywords Lighting, Energy  
  Abstract Today’s solar street LED lights are able to provide reliable, quality lighting both in developing and developed countries, thereby reducing light poverty and the economic and environmental costs of electric outdoor lighting. Rapid technical innovation and dramatic price reduction in the LED, PV module, and battery components, which has occurred in the last 5 years, will accelerate the penetration of solar street LED lights across the world. Applications will not be limited to countries with significant insolation only but will extend to Northern regions as well. This study provides a critical overview of a technology that will play an important role en route to global sustainability.

  Title Experimentally comparing the attractiveness of domestic lights to insects: Do LEDs attract fewer insects than conventional light types? Type Journal Article
  Year 2016 Publication Ecology and Evolution Abbreviated Journal Ecol Evol  
  Volume (up) 6 Issue 22 Pages 8028-8036  
  Keywords ecology; Lighting  
  Abstract LED lighting is predicted to constitute 70% of the outdoor and residential lighting markets by 2020. While the use of LEDs promotes energy and cost savings relative to traditional lighting technologies, little is known about the effects these broad-spectrum “white” lights will have on wildlife, human health, animal welfare, and disease transmission. We conducted field experiments to compare the relative attractiveness of four commercially available “domestic” lights, one traditional (tungsten filament) and three modern (compact fluorescent, “cool-white” LED and “warm-white” LED), to aerial insects, particularly Diptera. We found that LEDs attracted significantly fewer insects than other light sources, but found no significant difference in attraction between the “cool-” and “warm-white” LEDs. Fewer flies were attracted to LEDs than alternate light sources, including fewer Culicoides midges (Diptera: Ceratopogonidae). Use of LEDs has the potential to mitigate disturbances to wildlife and occurrences of insect-borne diseases relative to competing lighting technologies. However, we discuss the risks associated with broad-spectrum lighting and net increases in lighting resulting from reduced costs of LED technology.

  Title Efficient warm-white lighting using rare-earth-element-free fluorescent materials for saving energy, environment protection and human health Type Journal Article
  Year 2016 Publication RSC Adv. Abbreviated Journal RSC Adv.  
  Volume (up) 6 Issue 113 Pages 111959-111965  
  Keywords Lighting  
  Abstract Solid-state white light emission is important for energy saving, but currently it is mainly based on environmentally unfriendly rare-earth doped phosphors or cadmium-containing quantum dots. Here, we explore an environmentally friendly approach for efficient white light emission based on ZnSe:Mn nanoparticles without rare-earth or cadmium elements. The emission is composed of a broad green-orange spectral band (525–650 nm) with the peak located at 578 nm and the color temperature is low, so it is particularly good for lighting at night to reduce risks to human health. Furthermore, the optimal absorption peak could be designed at 453 nm, which well matches the commercial blue-LED emission wavelength (445–470 nm). A quantum yield up to 84.5% could also be achieved. This rare-earth-element-free material opens up a new avenue for energy-saving, healthy, and environmentally benign lighting.
