Liquid Cooling Technology for LEDs

By David Horn, SWITCH Lighting Co., San Jose, CA Best quality LED A-lamp light bulbs provide a superior, energy-efficient alternative to incandescent bulbs, which have essentially been banned as of January 1, 2014. LED bulbs offer the same amount of light as an incandescent while using up to 80 % less energy. There still remains, however, a wide discrepancy in performance between LED bulbs and what consumers expect from them as alternatives to standard incandescent bulbs. This variation in performance and cost can be largely attributed to how specific LED bulb manufacturers solve the challenge of removing heat from the LED components within their bulbs.

Finding the Optimal Lighting Solution for Line-Scan Applications

By Michael Geiser and Martin Hund, Chromasens, Konstanz, Germany In machine vision systems, acquiring images of moving targets is a challenge and consequently the best image requires three fundamentals to be well defined: an excellent camera; an appropriate lens; an appropriate illumination. All three items are the key to enable subsequent successful image analysis, while poor image quality will task any machine vision application.

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.
