Princeton University researchers have built another path forward for LED technologies. By refining the manufacturing of light sources made with crystalline substances known as perovskites, a more efficient and potentially lower-cost alternative to materials used in today’s LEDs can be made. Just as the complexity and bulkiness of CFLs distorted the engineering and lighting market, […]






Researchers at the University of Almería, Spain, determined LED lamps specifically designed for horticultural use were more beneficial to plant growth and had 26 percent higher energy efficiency when compared to conventional LED lamps. Conventional LED lamps are already known to offer better electrical energy efficiency. In horticultural operations, light-emitting diode (LED) lamps are becoming […]






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 […]
