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 ...

Discussion of "Electrocution by Street Lighting".

Survey on Street Lighting System Based On Vehicle Movements

Street Light Control System which operates automatically is not only easiest but also the intelligent system. This system can be set to operate in automatic mode, which regulates the streetlight according to brightness and dimness Algorithm and light intensity. This control can make a reasonable adjustment according to the seasonal variation. we can take the initiative to control streetlights t...

A Review of Street Lighting Evaluations: Crime Reduction Effects

Consideration of the literature concerning street lighting effects on crime yields the following conclusions: (1) Precisely targeted increases in street lighting generally have crime reduction effects. (2) More general increases in street lighting seem to have crime prevention effects, but this outcome is not universal Older and U.S. research yield fewer positive results than more recent U.K. r...

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...
