Purdue University researchers have published a study of supplemental lighting experiments in HortScience noting that light-emitting diodes are becoming a viable alternative to high-pressure sodium supplementation. The Purdue team collected physicochemical and sensory data in studies investigating the effect of supplemental light quantity and quality on greenhouse-grown tomatoes. The supplemental intracanopy LED lighting at the […]






Researchers at Aalto University and VTT Technical Research Center of Finland have succeeded in developing a method which helps to improve the relative uncertainty in measuring the luminous efficacy of LEDs. The improvement from the approximate five percent of today to one percent in the future may save billions in lighting costs in the future. […]






University of Toronto engineers have combined two promising solar cell materials together for the first time, creating a new platform for LED technology. The team has designed a way to embed the strongly luminescent nanoparticles called colloidal quantum dots into perovskite. Researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering invented […]






Hiroshima University researchers have announced fabrication of a silicon quantum dot based hybrid inorganic/organic light-emitting diode (LED) that exhibits white-blue electroluminescence. The hybrid LED is expected to be a next-generation illumination device for producing flexible lighting and displays. The fabrication was done by Professor Ken-ichi Saitow at the Natural Science Center for Basic Research and […]






Scientists from Tohoku University in Japan have developed a new type of energy efficient flat light source based on carbon nanotubes. The new flat panel technology has a very low power consumption of around 0.1 Watt for every hour’s operation making them about a hundred times lower in energy consumption than an LED. With only […]
