The Old North Church, a beacon for Paul Revere's famous warning of the movement of British forces, and a symbol of the American Revolution, has gone high-tech with the installation of light-emitting diodes, or LEDs. The energy-efficient lights illuminate ceiling vaults inside the church, whose steeple was used to display two lanterns as a signal about British troop movements on April 18, 1775 — the night described in Henry Wadsworth Longfellow's famous poem, which included the line: "One if by land, and two if by sea."

A real godsend for those of us in need of constant visual stimulus, the Oakland-based group Because We Can has devised a way to interact with your coffee table. The "Design-Build studio" teamed up with the tech whizzes from Evil Mad Scientist Laboratories to create an LED Coffee Table dubbed The Wave. They fitted the table with 480 bright LED lights, along with 32 near infrared optical sensors. The result is a surface that reacts to any motion by following it with a cascade of glowing light.

Mount these battery-operated lights along a stairwell, in a closet, outside your side door…wherever you need some light but don't need the hassle of electrical work.  Loud or sharp sound will turn the four bright LED lights on; they'll turn off automatically 10 seconds after last sound heard. Manual on/off option. Pivoting bracket directs the light where you need it. Weather-resistant for outdoor use.

Whever attention needs to be gained, it’s normal practice to flash LEDs. In addition to attracting the eye, flashing LEDs also considerably drops battery consumption.

A lamp that uses gravity to power light emitting diodes (LEDs) has been given a green award.The Gravia lamp designed by Virginia Tech student Clay Moulton earned second place in the Greener Gadgets Design Competition.Electricity to power the 10 high-output LEDs is generated by a weight that spins a rotor as it falls to earth.The weight is housed in an acrylic column, with the LEDs at its base shining through the acrylic to provide a diffuse glow.

A metal core printed circuit board (MCPCB) laminate for LED applications has been announced by Laird Technologies. The innovative environmentally-friendly new T-lam SS LLDlaminate is designed to keep bright and ultra-bright LED light engines burning brighter, longer and uniformly, says the company.T-lam SS LLD features a copper circuit layer and aluminium base plate bonded together with the company's T-lam LLD dielectric. T-lam SS LLD laminates are processed through standard circuit board manufacturing and assembly processes.

The inventor of the light emitting diode (LED) is set to join the inventor of the original light bulb when he is inducted into the National Inventors Hall of Fame.Nick Holonyack, who developed the first practical LED, will enter the pantheon which welcomed Thomas Edison when it first opened in 1973.

Dialight Corp.'s D264 Series LED-based flashing red beacons are being optimized for wind farm installations by two industry-leading OEM distributors.Dialight provides standard D264 beacons, which are modified to incorporate an integral photocell, controller and GPS-based synchronized flasher module in a compact design that eliminates the need for additional control cabinets and wiring, according to the company.

Carmanah Technologies Corporation has received an order through Dubai-based GESOLAR - the company's authorized aviation distributor in the United Arab Emirates (UAE) - to supply solar-powered portable airfield lights for privately-owned airfield applications within the region. The order, valued at more than $600,000, provides the tools to enhance visibility and safety at remote airfields using energy-efficient LED (light emitting diode) beacons powered by clean, cost-effective solar energy.

Light Emitting Diodes (LED) are changing the face of autos, inside and out, designers and engineers say. Once a beacon for the plush interiors of Lexus, Mercedes and Cadillac, LEDs have made their way into daily drivers such as the Ford Focus and Chevy Malibu, and certainly will make their way into more. Interior and exterior designers love the little light bulbs and are finding new ways to use them.

Atlas Electrical Technologies Services designed and installed an anti collision system that supervises the work area limits, gathers information on the proximity of these limits and prevents dangerous movements. This involves radio telecommunication features which aid in establishing limiting features to prevent jib to jib, jib to load and jib to tower deck collision. The system also has zone points along loading bays, traffic lanes and edges of buildings where the cranes should not tread.

  You can forget the Wii, PS3 or iPhone right now. The most exciting product unboxing of the 21st century is here, and it dumps on all of 'em from a great height. Oh yes, Tech Digest has the exclusive on the Tchibo Tweezers with LED. That's right: laser-guided tweezers (almost).

14-gauge, 25' black cable with 3 outlets spaced evenly apart. CBI MOX Series cords are engineered for easy storage and the elimination of twisted cords.

A new study has shown that a coating of carefully tuned nanocrystals helps make LED light warmer and less clinical. Hilmi Volkan Demir of Bilkent University in Ankara, Turkey, says that this development may pave the way for energy-efficient LED lights headway in the commercial market. He has revealed that nanocrystals show promise to create LEDs that give off a warm white light, with efficiency far beyond compact fluorescents.

The PL-Pro II Power Conditioner serves up Furman's Series Multi-Stage Protection (SMP) and Linear Filter Technology (LiFT).

Austin Energy is joining a national effort to develop new, energy efficient light bulbs made from LEDs. Those light-emitting diodes are commonly used in billboards and traffic signals, and new developments in the field mean they could soon be used in everyday office and home environments.
