Compact Range LEDs

Mouser Electronics, Inc. (Mansfield, TX) is now stocking LUXEON CoB Compact Range LEDs from Lumileds (San Jose, CA). These LEDs offer high flux densities in a very small light emitting surface (LES), which provides good center beam candle power (CBCP). The Lumileds LUXEON CoB Compact Range LEDs feature a single 6.5mm optical LES that provides high flux densities and high efficacy. Industry-leading thermal resistance allows for smaller heat sinks, and the assembly’s ceramic substrate offers excellent protection in high-potential (HiPot) testing.

Flexible Light Engine Material

Norlux (Elgin, IL) has introduced new NorFlex brand flexible continuous light engine material. The cuttable high-power LED circuits on a semi-rigid material provide 5x the lumen output of low power flex materials. Available on 200-400 ft. reels, the material is cuttable to maximize production flexibility. No special tools required! Most parameters are customizable – width, length, CCTs, LED spacing, power levels, custom components, etc. Both Constant-Current and Constant-Voltage versions are available. NorFlex circuits are designed to provide superior thermal performance, eliminating the need for big heat sinks. Suitable for fixtures with curved surfaces, low profiles or edge-lit.

Will iris detection become a mainstream smartphone feature?

This week's Question: The Fujitsu Arrows NX F-04G, a new smartphone set for release in Japan, comes with a built-in retinal scanner that can be used for a variety of different functions, including unlocking the device, accessing apps, and making mobile payments. A front-facing infrared camera and an infrared LED light illuminate the user's eyes, verifying his or her unique iris pattern. Although the technology is currently only available in Japan, bigger companies like Samsung are also working on iris-detecting smartphones. What do you think? Will iris detection become a mainstream smartphone feature?

Will "smart city" lighting efforts pay off?

This week's Question: At this year's Mobile World Congress in Spain, Sierra Wireless and Philips CityTouch demonstrated "smart city" lighting capabilities. The companies' systems connect a city's individual street lights to the Internet via 2G, 3G, and 4G networks. The "smart" technology allows authorities to create customized lighting patterns and adjust the lamps for specific weather conditions or neighborhood needs. With "smart city" designs, users will potentially gain a clearer picture of a city’s lighting infrastructure, access real-time data on energy consumption, and receive automatic failure notifications, ultimately reducing costs in both energy and maintenance. To achieve this type of connected city, however, a common set of standards must enable interoperability so that every application can communicate and share data. Security levels, too, must be maintained. What do you think? Will "smart city" lighting efforts pay off?

High-Performance Photocatalytic Oxidation Reactor System

Airborne volatile organic chemicals are oxidized using blue LEDs, fiber optics, and visible light-activated catalysts for space and terrestrial air purification. Marshall Space Flight Center, Alabama As crewed space missions extend beyond low Earth orbit, the need to reliably recover potable water is critical. Aboard the International Space Station (ISS), the water is recycled from cabin humidity condensate, urine distillate, and hygiene wash wastes. In spacecraft cabin air environments, off-gassing from equipment, human metabolism, and human personal care products contributes to significant airborne concentrations of volatile organic compounds (VOCs). These polar and water-soluble compounds ultimately dissolve into the humidity condensate and stress the process load, logistics costs, and lifecycle requirements of the water processing systems. The aim of this effort was to develop the High Performance Photocatalytic Oxidation Reactor System (HPPORS) technology for the destruction of airborne VOCs prior to reaching the water processing systems. This innovation will reduce the logistics costs and lifecycle requirements of water processing systems, and help extend NASA missions to include long-duration space habitation and lunar and Mars colonization missions.

Public Lighting System Runs on Solar and Wind Energy

A researcher at the Barcelona College of Industrial Engineering, in collaboration with the company Eolgreen, has developed the first autonomous industrialized public lighting system that works with solar and wind energy. This system, developed after four years of research, is designed for inter-urban roads, motorways, urban parks, and other public areas. It is unique in the world, and reduces the cost by 20% compared with conventional public lighting systems. The prototype is 10 meters high and is fitted with a solar panel, a wind turbine, and a battery. The turbine runs at a speed of 10 to 200 rpm and has a maximum output of 400 watts. Work is being done on a second prototype generator that runs at a lower speed (10 to 60 rpm) and has a lower output (100 W). An electronic control system manages the flow of energy among the solar panel, the wind turbine, the battery, and the light. Source:
