Research on the Lighting Performance of LED Street Lights With Different Color Temperatures
IEEE Photonics Journal, 2015 While light-emitting diodes (LEDs) are a very efficient lighting option, whether phosphor-coated LEDs (PC-LEDs) are suitable for street lighting remains to be tested.

Ecological effects of artificial light at night on wild plants [PDF]
, 2016 PublishedSummary 1.Plants use light as a source of both energy and information. Plant physiological responses to light, and interactions between plants and animals (such as herbivory and pollination), have evolved under a more or less stable regime of ...

Artificial Light Increases Nighttime Prevalence of Predatory Fishes, Altering Community Composition on Coral Reefs. [PDF]
Glob Chang BiolArtificial light is a manmade pollutant that is spreading into marine environments, and coral reefs are particularly susceptible to biological impacts due to the inshore, shallow, and clear‐water locations that they thrive in. We manipulated artificial light at night on a Polynesian coral reef to study its impact on nighttime fish communities.

Establishing a Large-Scale Field Experiment to Assess the Effects of Artificial Light at Night on Species and Food Webs [PDF]
, 2015 Artificial light at night (ALAN) is one of the most obvious hallmarks of human presence in an ecosystem. The rapidly increasing use of artificial light has fundamentally transformed nightscapes throughout most of the globe, although little is known about

Human alteration of natural light cycles: causes and ecological consequences. [PDF]
, 2016 Artificial light at night is profoundly altering natural light cycles, particularly as perceived by many organisms, over extensive areas of the globe. This alteration comprises the introduction of light at night at places and times at which it has not ...

Approximate Inference for Constructing Astronomical Catalogs from Images
, 2019 We present a new, fully generative model for constructing astronomical catalogs from optical telescope image sets. Each pixel intensity is treated as a random variable with parameters that depend on the latent properties of stars and galaxies.

Reducing the ecological consequences of night-time light pollution: options and developments. [PDF]
, 2016 1. Much concern has been expressed about the ecological consequences of night-time light pollution. This concern is most often focused on the encroachment of artificial light into previously unlit areas of the night-time environment, but changes in the ...

Ecography, Volume 2026, Issue 3, March 2026.The regular variations of light in the natural light cycle serve as one of the most important cues for the timing of biological events in organisms. The increasing prevalence of artificial light at night (ALAN) alters the natural light cycle and has been found to have harmful effects on human, wildlife, and environmental health.
