An accelerated test method for predicting the useful life of an LED driver
(Rensselaer Polytechnic Institute, Troy, NY, 2009-12) -
Changes in electrical and thermal parameters of LED packages under different current and heating stresses
(Rensselaer Polytechnic Institute, Troy, NY, 2013-12)Experiment results showed that the series electrical resistance went through four phases of change; including periods of latency, rapid increase, saturation, and finally a sharp decline just before failure. Formation of ... -
Changes in spectral sensitivity of the human circadian system
(Rensselaer Polytechnic Institute, Troy, NY, 2009-08) -
Characterizing the thermal resistance of alternating current light emitting diodes
(Rensselaer Polytechnic Institute, Troy, NY, 2011-12) -
Effect of different colored background lighting on led glare perception
(Rensselaer Polytechnic Institute, Troy, NY, 2011-08) -
Investigating melanopsin contribution to scene brightness perception
(Rensselaer Polytechnic Institute, Troy, NY, 2013-12)Experiment 1 used a "Green" stimulus composed of LED illumination peaking at 525 nm and 625 nm, and a "Fuchsia" stimulus composed of LEDs peaking at 465 nm and 625 nm. S-cone stimulation from the Green stimulus was only ... -
Strategies for optimizing light therapy efficacy in Alzheimer's disease patients
(Rensselaer Polytechnic Institute, Troy, NY, 2013-05)Dependent variables gauging the performance of the novel luminaires include illuminance measured at the eye and corresponding circadian light (CLA) and circadian stimulus (CS) values. Parameters assessing the circadian ... -
The effect of self-luminous electronic displays on melatonin
(Rensselaer Polytechnic Institute, Troy, NY, 2012-12) -
The impact of 470-nm light on acute nocturnal melatonin suppression
(Rensselaer Polytechnic Institute, Troy, NY, 2011-12)
