Redesigning Public Street Lighting Using Photometric Method

Street Lighting Disturbs Commuting Bats

Anthropogenic disturbance is a major cause of worldwide declines in biodiversity. Understanding the implications of this disturbance for species and populations is crucial for conservation biologists wishing to mitigate negative effects. Anthropogenic light pollution is an increasing global problem, affecting ecological interactions across a range of taxa and impacting negatively upon critical ...

High-performance LED street lighting using microlens arrays.

An efficient LED lamp that illuminates the street with high quality is presented. The luminaire shows high optical efficiency, high optical utilization factor, low glare, and illuminates the street with high uniformity. The concept is simple but effective: a cluster of LEDs with TIR lenses are put inside a reflective box, which is covered with a microlens sheet; the reflective cavity improves e...

Smart Street Lighting & Automated fault detection using power consumption data

Street lighting systems are one of the key infrastructures of a city and are important for safe driving and safety of the pedestrians. Also, owing to the large number of lamps, street lighting accounts to high energy consumption and thus a significant cost to the utilities. Smart street lighting solutions enable control, monitoring and automatic fault detection, transforming these systems into ...

Discussion of "Electrocution by Street Lighting".

Albedo Recovery Using a Photometric Stereo Method

This paper describes a method for the calculation of surface reflectance values via photometric stereo. Experimental results show that surfaces rendered with reflectance values calculated by the proposed method have more realistic appearances than those with constant albedo. 1 Center for Image Technology and Robotics Tamaki Campus, The University of Auckland, Auckland, New Zealand. 2 Agilent Te...
