LED Street Lights Reduce Energy Consumption by 72% at Power Station

When the NRG power plant in El Segundo, Calif., was redesigned, two towers were demolished which caused extensive light from the plant to bother local neighbors. In an effort to get rid of this light pollution and update old lighting fixtures at the same time, NRG turned to LEDtronics, Inc. for assistance.

Production Company Uses LED Street Lights To Illuminate Dark Parking Lot

Solar Energy Technologies, Inc., Hialeah, FL MaxLite, West Caldwell, NJ Imagina US is a pioneer production company in the U.S. Hispanic TV industry that has a newly built headquarters in Miami, Florida. Owners were seeking low-wattage outdoor lighting for the facility’s parking lots. At first, the owners were looking at 400-watt metal halide fixtures, however, they wanted to consider lower wattage and better quality LED lighting fixtures.

Customized Goniophotometer System Tests High Intensity Obstruction Lights

Hughey & Phillips (H&P), Urbana, OH Hughey & Phillips (H&P) designs and manufactures flashing and steady state anti-collision lighting used on above-ground obstructions like communication towers, antennas, buildings, wind turbines, grain elevators, smoke stacks, bridges and other man-made structures that are potential collision hazards for aircraft. Used as either standalone fixtures or as part of integrated systems, these low, medium, and high intensity lighting devices illuminate obstructions to aerial navigation as specified by the FAA, FCC, ICAO, DGAC of Mexico and Transport Canada. The required light output intensity of H&P’s products increases with altitude - the higher the elevation, the greater the required output intensity.

First Single-Molecule LED Developed

Breakthrough could be the first step towards making molecule-sized components that combine electrical and optical properties. Institut de Physique et de Chimie des Matériaux de Strasbourg, Strasbourg, France The ultimate challenge in the race to miniaturize light emitting diodes (LED) has finally been met. A team led by the Institut de Physique et de Chimie des Matériaux de Strasbourg (IPCMS, CNRS/Université de Strasbourg), in collaboration with UPMC and CEA, has developed the first-ever single-molecule LED.

Two-Dimensional Material Shows Promise for Optoelectronics

Team creates LEDs, photovoltaic cells, and light detectors using novel one-molecule-thick material. Massachusetts Institute of Technology, Cambridge, MA Ateam of MIT researchers has used a novel material that’s just a few atoms thick to create devices that can harness or emit light. This proof-of-concept could lead to ultra-thin, lightweight, and flexible photovoltaic cells, light emitting diodes (LEDs), and other optoelectronic devices.

Improving the Efficiency of Green-Blue-Ultraviolet Light-Emitting Diodes

New approach could lead to the creation of low threshold lasers and high power light emitting diodes (LEDs). U.S. Naval Research Laboratory, Washington, DC Scientists at the U.S. Naval Research Laboratory (NRL) have suggested a method that could significantly increase the efficiency of green-blue-ultraviolet light-emitting diodes based on GaInN/GaN, AlGaN/GaN, and AlInN/GaN quantum wells. Their approach could enable advances in solid state lighting and the creation of low threshold lasers and high power light emitting diodes (LEDs).

Scientists Build Thinnest-Possible LEDs To Be Stronger, More Energy Efficient

University of Washington Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based on semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for semiconductors that are tinier, stronger and more energy efficient.
