LEDs Offer a Huge Improvement to Greenhouse Lighting

May 11, 2016 | 1 Comment

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 […]

Can LEDs Work In Greenhouses?

December 30, 2015 | Leave a Comment

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 […]

Pure Perovskite Crystals For Better LEDs and Solar Panels

February 5, 2015 | Leave a Comment

University of Toronto engineers have grown large and pure perovskite crystals. Perovskite crystals are an emerging family of solar-absorbing materials that could clear the way for cheaper and more efficient solar panels and LEDs. These materials are particularly good at absorbing visible light, but had never been thoroughly studied in their purest form: as perfect […]

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 […]

Wonder Material Perovskite Destined For LEDs

August 7, 2014 | 2 Comments

A hybrid form of perovskite, the same type of material that has recently been found to make highly efficient solar cells that could one day replace silicon, has been used to make low-cost, easily manufactured LEDs. This particular class of semiconductor perovskites has generated excitement in the solar cell field over the past several years, […]
