LED Drivers

SL Power Electronics (Ventura, CA) has introduced its new LE Series of LED drivers. Available in 10 models from 75 to 300 watts, the constant current LED drivers enable highly efficient LED lighting for applications that require more than eight hours per day of operating life. Featuring a wide input voltage range of 90 to 305 VAC, up to 95 percent efficiency and the ability to survive lightning strikes, the LE-Series have UL 8750 and EN61347 safety approvals with an IP67 rating and are housed in a waterproof metal case in order to withstand hot and cold temperatures in outside installations.

Aluminum Body LED Work Light

The EPL-FL1524-LED-120X12- C1D2-50 hazardous area LED work light from Larson Electronics (Kemp, TX) provides operators with a far more durable and reliable high performance alternative to standard incandescent and fluorescent work lights. This LED drop light is designed similarly to a standard fluorescent drop light, but offers greatly improved performance and durability through the inclusion of a 15 watt LED tube lamp instead of the usual fragile fluorescent tube. This light produces more light output than a standard 100 watt incandescent drop light, has no glass to shatter or break, has no filament, and runs only slightly warm to the touch. This light produces 1,450 lumens of clean white light output from only 15 watts of power consumption.

Big Ideas for Small Spaces

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.

Transient Electronics Dissolve When Triggered

An Iowa State research team led by Reza Montazami is developing "transient materials" and "transient electronics" that can quickly and completely melt away when a trigger is activated. The development could mean that one day you might be able to send out a signal to destroy a lost credit card.To demonstrate that potential, Montazami played a video showing a blue light-emitting diode mounted on a clear polymer composite base with the electrical leads embedded inside. After a drop of water, the base and wiring began to melt away. As the technology develops, Montazami sees more and more potential for the commercial application of transient materials. A medical device, once its job is done, could harmlessly melt away inside a person’s body. A military device could collect and send its data and then disappear, leaving no trace of an intelligence mission. An environmental sensor could collect climate information, then wash away in the rain. SourceAlso: Read other Electronics & Computers tech briefs.

New Approach To Growing InGaN Crystals For Diodes Could Also Improve Solar Cell Efficiency

Metal-modulated epitaxy allows an atomic, layer-by-layer growth of the material. Crystals form the basis for the penetrating icy blue glare of car headlights and now they could be fundamental to the future in solar energy technology? Crystals are at the heart of diodes. Not the kind you might find in quartz, formed naturally, but manufactured to form alloys, such as indium gallium nitride or InGaN. This alloy forms the light emitting region of LEDs, for illumination in the visible range, and of laser diodes (LDs), in the blue-UV range.

New Plastic-Like Polymer Could Lead To White Organic LEDs

Inserting platinum metal atoms into a chain-like organic polymer enabled tuning of the colors emitted. By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to “tune” the plastic-like polymer to emit light of different colors – a step toward more efficient, less expensive and truly white organic LEDs for light bulbs of the future.

LED Panels Illuminate Stained Glass Window

The newly-renovated Church of the Covenant in Cleveland, Ohio, has a large, ornate rose stained-glass window that faces the Seidman Cancer Center at the University Hospitals Case Medical Center across Euclid Avenue. In a joint partnership project between the church and hospital entitled, “Hands Across the Healthway,” the neighbors wanted to find a way to illuminate the stained glass window so that recovering patients can view the illumination.
