Recently, the Sentry Equipment Corp. in Oconomowoc, Wis., was considering how to light its new factory, the company's president, Michael Farrell decided to try LEDs. At last he chose to light the building's exterior and most of its interior with LEDs, a light source that many bulb manufacturers are now convinced will supplant incandescent and compact fluorescent bulbs.

According to analysts at the Darnell Group market research firm in Corona, Calif, LED will rapidly accelerate over the next few years in general illumination applications.

LED luminous letter (or caption machine) adopts light emitting diode as lighting source. It is usually installed on the top of buildings or on wall surface in the shape of given letters or signs. LED luminous letter chooses high brightness LED chips and uses specific system to take control of the dynamic video of the letters or signs. The unique designed LED luminous letter surpasses the traditional outdoor advertisement in function. Its abundance colors make it much superior than traditional neon light and make break through in application variety.

According to counters Jeff Shepard, president of Darnell Group, the impending displacement of cold-cathode fluorescent lamps by LED backlights in the laptop computer market is only one of the most visible indicators, and analyzed over 50 application sub-segments in detail to arrive at our growth trajectories. Growth in these applications will drive down the cost of LEDs is quite faster. And growth is accelerating in numerous market segments including video signs and billboards, automotive lighting, and others.

It's reported Seoul Semiconductor has recommended a new Top-View LEDs with high CRI, high efficacy and high reliability. Generally, the Warm White part (CAWT722-S) has a CRI of 96 and achieves 68 lm/W, while the Pure White (CWT722-S) has a CRI of 92 and produces 70 lm/W. moreover, it is important to note that these figures are for a drive current of 60 mA and a power consumption of 0.192 W. The light output of the pure white and warm white devices is only 13.9 and 13.1. lm, respectively.

According to the expert's analysis, OLED lighting is more than twice as efficient as regular incandescent light bulbs by using a new process that involves tiny micro lenses, cranking out 70 lumens of light per watt of power, compared with the 30 lumens per watt of GE's latest OLEDs. While these fantastic new lighting sources won't light up every house for a few more years, they'll be a whole lot better than current compact florescent bulbs.

Recently Universal Display Corporation through its UniversalPHOLED™ technology, announced a $1,918,878, two-year U.S. Department of Energy contract to accelerate development of white OLED lighting products. Universal Display plans to use Armstrong World Industries as a key subcontractor to fulfill the requirements of the grant. Funded through the U.S.

According to the latest research, LED strips in both rigid and aluminiumLEDS-R-US, a subsidiary of Eco Living Centre , offers the home renovator, providing a long lasting and low energy use globe. Usually, LED lighting generates very little heat, has a small footprint, and has a variety of colour options. The added benefit is their long life >50,000 hours or 6.2 years of 24/7 operation and low power consumption.

It's reported Toshiba Corp. and Matsushita Electric Industrial Co. Ltd. said that they will mass produce next-generation organic displays, spending roughly $140 million to cash in on the growing market for the ultra-thin screens On July 22.

It's reported Taiwan-based LED chipmaker Arima Optoelectronics has stressed that its finances and operations remain healthy despite heavy losses in 1Q.The company saw its June sales drop 59% on year to NT$104 million, with a net loss of NT$82 million for the month. It posted net losses of NT$124 million for the first quarter of 2008. It attributed the poor results to the spinning off its laser diode business last August, and fierce pricing amid weak demand.

Energy efficiency and flexible lighting applications of OLEDs hasn't lived up to its promise, however, because in typical OLEDs, only 20 percent of the light generated is released from the device. That means that most light is trapped inside the bulb, making it highly inefficient. It's reported the scientists are on to a way to break the OLED-efficiency logjam. TThey have designed an OLED that boosts illumination by 60 percent using a combination of an organic grid working in tandem with small micro lenses that guide the trapped light out of the device.

It's reported Osram is claiming a record for luminous flux and efficacy from an LED driven at 350 mA. It says that its development engineers have achieved new records for the brightness and efficiency of white LEDs in the laboratory. Under standard conditions with an operating current of 350 mA, brightness peaked at a value of 155 lm, and efficacy at 136 lm/W. White prototype LEDs with 1 mm2 chips were used. The light produced had a color temperature of 5000 K, with color (x,y) coordinates at (0.349, 0.393).

It's reported Purdue's Professor Sands and a graduate researcher man the reactor, which produces the first blue LEDs based on a silicon process. The new LEDs promise greater efficiency, longer lifetimes, and much lower costs. Purdue research have developed new production methods which will cut LED lighting costs to about a twentieth of current expenses.

The technique overcomes prohibitive costs of current LED technology by building the diodes on low cost silicon wafers, instead of currently-used sapphire. LEDs are said to be four times more efficient than conventional incandescent lights, more environmentally friendly than compact fluorescent lights, and have a far longer lifespan of up to 15 years.

In the past, high power LED lighting has been one of the technical revolutions. Filament lamps have reigned supreme for something like a century, are now being replaced by LEDs.But using high power LEDs has never been as simple as using filament lamps - what with the need to control current by a dropping resistor or a DC:DC converter. for example, take the replacement of an interior car light. By the time you source a LED of sufficient intensity and organize and position a dropping resistor, it's a project that very rapidly loses appeal!
