Nano-Layer Deposition Tool and Processes Will Support Advanced Development for HB-LEDs at one of the world's foremost manufacturers.

Dozens of and even hundreds of LEDs need to be connected together to form a light emitting device in commercial practices. The connection mode of LED load circuit will directly influence the reliability and life-span of the LED. The LED circuit which can work safely has the following 2 basic functions: to keep the current constant and to maintain low power consumption for the circuit itself. Only in this way can the LED system efficiency stays in a higher level.

LED is made up of a very small chip packaged in the epoxy resin. Generally, the operating voltage is 2-3.6V and the operating current is 0.02-0.03A. Traditional incandescent lamp emits light depending on tungsten filament, and the power-saving lamp depends on tricolor powder. Different from these two kinds of lamps, LED emits light through electric field. Long lifespan, high efficiency, absence of radiation and energy saving is the advantages of LED light. These advantages destined it to replace traditional light sources and to be used extensively.

Now when the lights go low, the bocce won't have to stop when you have these LED bocce balls. Included in the set are nine colored balls in white, yellow, red, green and blue that all have embedded LEDs.

Delta Electronics, Inc. announced it has developed an advanced, energy-saving High Brightness 5W/9W/12W LED Lamp, and will demonstrate the new lamp at the Light+Building 2008 exhibition in Frankfurt, April 06-11. The LED lamp is 100% compatible with current sockets (E27) and is similar in appearance to compact fluorescent lamps (CFL) of the same wattage. The lamp is easily installed and readily replaces CFL and incandescent lamps.

The lights are a little whiter and a little brighter in part of St. Paul as part of an experiment with LED streetlights. The city's environmental policy director, Anne Hunt, says it is experimenting with the new lights because they are greener, last longer and cheaper to operate. Paul is following Austin, Texas; Anchorage, Alaska and Ann Arbor, Michigan, in installing the lights. A few smaller Minnesota cities have also tried them.

STMicroelectronics , a world leader in power applications, has introduced three monolithic step-up converters for LED backlights and lighting, providing 30mA or 85mA current sources for six rows of up to 10 white LEDs. The LED7706, LED7707 and mobile-optimized PM6600 include on-chip MOSFETs to reduce part count, and operate up to 1MHz to minimize filter components.

LED-backlit LCD TVs, enabled by Dolby Laboratories' High Dynamic Range (HDR) technology, produce stunningly clear pictures. Unclear, though, is how much consumers will have to pay for that kind of picture quality. "These products have been screaming to get out to a mass market," said Eric Haruki, research director for TV markets and technologies at IDC. But he cautioned that unless LED manufacturers can achieve the economies of scale and cut the cost of LEDs, "this could still remain a great white hope for awhile."

Jesco LED has released its new DL-Flex-Up series, a flexible 3/8" X 1/8" X 12" PCB with high output, 110 degree or 65 degree LEDs in three color temperatures. The colors available include 3000K, 4100K, and 6000K white with an outstanding evenness of distribution. The strips are modular with flat mini-plugs eliminating in-field soldering, and special controllers that provide the designer the means to install these mini-light sources in the tightest locations.

Marumi's little ring-light uses LEDs instead of a flash tube, which has a couple of advantages. You can preview the light's effect on the image, and batteries will last a lot longer. Digital photography means that the color of light doesn't matter nearly as much as it did with film, but mixed lighting can still cause problems. The LEDs on the Marumi are daylight balanced.

It's reported that St. Paul is trying to take on a whole new light. A block of St. Paul's Iowa Avenue, between Chatsworth and Milton Streets, is lit with light-emitting diode, or LED, streetlights. The lights are brighter and save on energy costs, but some worry about the lighting levels. The city is testing them to see whether they can cut energy use and maintenance costs.

Seekway has put together this spectacular 3D LED display, which is capable of displaying images in full 3D (duh) at an amazing, 30 fps. The prototype consists of a 16 x 16 x 16 grid of interconnected colour LEDs and if our mathematics doesn't fail us, that's 4096 individual diodes.

Carmanah Technologies Corporation has received an order to supply solar-powered portable airfield lights for Bariven S.A. in Venezuela, a subsidiary of PDVSA. The order, valued at over $800,000 USD, will provide the tools to equip Venezuela's Carupano Airport with a stand-alone system of solar-powered LED (light emitting diode) aviation lights.

Currently, the luminous efficacy of power LEDs is around 50lm/W (lumens/watt), which does not meet the requirements for home lighting. Therefore, many problems remain to be tackled to boost the power WLEDs (White LEDs) into home lighting, of which the luminous efficacy is the key factor. Although there are many factors which can influence the luminous efficacy of WLEDs, the following ones are worth paying attention to.

Ann Arbor is installing its new energy-efficient LED streetlights one block at a time in its downtown district. Tree Town is also testing new ways to save more energy in the way it provides public light. One block at a time. That's how quickly Ann Arbor is changing its downtown street lights to more energy-efficient LED lights this year.The city's energy department recently started relamping the street lights and so far has three blocks (on Washington Street between 5th and Ashley streets) of new LEDs in place.
