  Title Effect of illuminance and spectrum on peripheral obstacle detection by pedestrians Type Journal Article
  Year 2015 Publication Lighting Research & Technology Abbreviated Journal  
  Volume (down) 49 Issue 2 Pages 211-227  
  Keywords Public Safety; Lighting  
  Abstract Obstacle detection is an important visual task for pedestrians. An experiment was carried out to measure the ability to detect peripheral obstacles under variations of illuminance and scotopic/photopic luminance ratio and with older and younger test participants. The LED array used in this work enabled scotopic/photopic ratio to be varied whilst chromaticity was held constant. The tests employed a full-scale model with dynamic fixation and walking to better simulate pedestrian experience than in past work. Detection performance increased with illuminance, reaching a plateau at 2.0 lux. A higher scotopic/photopic ratio improved obstacle detection but only at the lowest illuminance used in this study (0.2 lux). Older participants showed poorer obstacle detection performance than younger participants but again only at the lowest illuminance.

  Title Insect reactions to light and its applications to pest management Type Journal Article
  Year 2013 Publication Applied Entomology and Zoology Abbreviated Journal Appl Entomol Zool  
  Volume (down) 48 Issue 4 Pages 413-421  
  Keywords ultraviolet; light; Integrated pest management; Artificial lighting; Photoreception; Phototaxis; Light-emitting diode; *Lighting  
  Abstract Insects are able to see ultraviolet (UV) radiation. Nocturnal insects are often attracted to light sources that emit large amounts of UV radiation, and devices that exploit this behavior, such as light traps for forecasting pest outbreaks, and electric insect killers, have been developed. Some diurnal species are attracted to yellow; yellow pan traps are used for conducting surveys for pest outbreaks and yellow sticky plates are used for pest control. Lamps that give off yellow illumination have been used effectively to control the activity of nocturnal moths and thus reduce damage to fruit, vegetables, and flowers. Covering cultivation facilities with film that filters out near-UV radiation reduces the invasion of pests such as whiteflies and thrips into the facilities, thus reducing damage. Reflective material placed on cultivated land can control the approach of flying insects such as aphids. Future development and use of new light sources such as light-emitting diodes is anticipated for promoting integrated pest management.

  Title Energy and user acceptability benefits of improved illuminance uniformity in parking lot illumination Type Journal Article
  Year 2015 Publication Lighting Research and Technology Abbreviated Journal Lighting Res. & Tech.  
  Volume (down) 48 Issue 7 Pages 789-809  
  Keywords Lighting; parking lots; uniformity; light distribution; illuminance; LED  
  Abstract This study set out to understand the benefits of improved illuminance uniformity in parking lots in terms of user perception and acceptability, as well as energy use, and to demonstrate that light-emitting diodes (LEDs) can achieve uniform distributions more efficiently than traditional light sources. The results from a field evaluation showed that more uniform illuminance distributions are favourably perceived by people in terms of goodness of illumination, ability to see around and at a distance, and perception of safety -- all of this at a much lower average horizontal illuminance. Thus, improving uniformity alone can translate into lower energy use and potential for less glare and light pollution. Optical modelling showed that LEDs have a much greater potential to efficiently produce uniform illuminance distributions than larger light sources such as high pressure sodium or metal halide.

  Title Applicability of mesopic factors to the driving task Type Journal Article
  Year 2015 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology  
  Volume (down) 48 Issue 1 Pages 70-82  
  Keywords Lighting; Public Safety; Planning  
  Abstract With the advent of light-emitting diode technology being applied to roadway lighting, the spectral power distribution of the light source is becoming much more important. In this experiment, the detection of pedestrians at five adaptation levels under three light sources, high pressure sodium and light emitting diodes of two colour temperatures was measured in realistic roadway scenarios. The results show that while the light source type was not significant, an increase in adaptation luminance increased the detection distance. As the offset of the object to the roadway increased, some spectral effects became more significant; however, this effect was not consistent across all angles of eccentricity. The conclusions from this work indicate that mesopic factors may not be applicable on high-speed roads.

  Title Advanced lighting technology in controlled environment agriculture Type Journal Article
  Year 2016 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology  
  Volume (down) 48 Issue 1 Pages 83-94  
  Keywords Plants; Lighting  
  Abstract There is a recent awareness of the importance of plants in our everyday lives. Light is a requirement for plants and serves two important roles. It provides energy for growth and provides information that elicits plant responses including, among others, plant shape, pigmentation, nutritional content and resistance to stress. Light is paradoxical to plants, it is a requirement however, in excess it is damaging. Plants sense and interpret light through many families of photoreceptors and through the energy state of the photosynthetic apparatus. Light emitting diodes (LEDs) are quickly replacing traditional light sources for human applications, and currently there is effort being put into tailoring these technology platforms for the plant community. Potential plant sensing pathways and the spectral effects on pigmentation and photochemistry in red lettuce are described.
