Improved Design and Recommendations for Street Lighting in Gitega City

Design Guideline on 150W Power Supply for LED Street Lighting Design Using FL7930B and FAN7621S

Sustainable Street Lighting Design Supported by Hypergraph-Based Computational Model

Street lighting systems are significant energy consumers in urban environments. The important step toward the reduction of this energy consumption and, thus, finding a balance between functional requirements and savings-related demands, was introducing LED-based light sources. There still exists, however, a margin for further savings, which is associated with well-tailored designs of road light...

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 ...

Recommendations for Improved Development by Design*

This paper challenges several of the accepted methods of practical engineering and product development for groups and situations in less industrialized economies. The underlying argument is that all activities related to product design, development, dissemination, and reporting must be of the highest possible quality and user-centric regardless of the economic environment. Five key points are a...

Interactive Global Illumination for Improved Lighting Design Workflow

In this paper, we present a hybrid software–hardware rendering technique which can compute and visualize global illumination effects in dynamic scenes at interactive rates. Our system uses a hardware splatting technique simular to, but developed independently of, Stüerzlinger et al. The technique involves a progressively refined photon tracing calculation capable of simulating a wide range of B...
