Photobiocatalytic alcohol oxidation using LED light sources

Color Rendering Properties of LED Light Sources

A laboratory human factors experiment was conducted to understand the color rendering properties of various LED-based reading lights. Human subjects rated their preference for a given scene illuminated by a test light source compared to an identical scene illuminated by a reference light source. In another experiment the same subjects viewed and rated the scenes individually when illuminated by...

Light-induced retinal damage using different light sources, protocols and rat strains reveals LED phototoxicity.

To save energy, the European directives from the Eco-design of Energy Using Products (2005/32/CE) have recommended the replacement of incandescent lamps by more economic devices such as Light Emitting Diodes (LEDs). However, the emission spectrum of these devices is enriched in blue radiations, known to be potentially dangerous to the retina. Recent studies showed that light exposure contribute...

The asymmetries of colour constancy as determined through illumination discrimination using tuneable LED light sources

reveals " blue " bias for colour constancy in real and simulated scenes. On calculating metamer sets for spectrally tunable LED illuminators. Are colour constancy mechanisms biased for typical illuminations? AIC 2013. Abstract The light reflected from object surfaces changes with the spectral content of the illumination. Despite these changes, the human visual system tends to keep the colours o...

Comparison of Latent Print Detection using Semiconductor Laser and LED Light Sources with Three Chemical Reagents

A variety of light sources and reagents are available for the detection and identif ication of latent prints. This study was undertaken to explore the optimum light and f ilter combinations of laser and light-emitting diode (LED) light for use with indanedione and two new reagents, genipin and lawsone. The light sources utilized were Coherent TracER lasers operating at 460 nm, 532 nm, and 577 n...
