says that although the aesthetically pleasing technology will improve over the next decade, and become much cheaper than today, it will still be far too expensive for mainstream use.
As a result, says Lux, OLED lighting will command just a $58 million market by 2020, with the technology only making a significant penetration into high-end applications such as designer lighting, casinos and upmarket bars and restaurants. If correct, it will mean that the wider market for OLEDs will be almost totally dominated by display applications such as phone handsets and televisions.

conservatives does it take to screw up a light bulb law that sets a higher bar for energy-efficient bulbs -- a law that was passed during Geroge W. Bush’s administration, no less? With any luck we won’t find out. While Republican lawmakers push back against modern bulbs in favor of old-fashioned bulbs, hopefully consumers will continue to forge their own path by embracing the modern bulbs that the light bulb industry has already developed.
Part of the WinonaLED product family, the Winline 607 LED Submersible Light is an LED linear water-cooled submersible luminaire. Available in various color temperatures and in sizes from 30" to 54" in length, the fixture delivers up to 1840 lumens per foot. Its stainless steel end cap and pure copper center tube, as well as its high-impact UV resistant polycarbonate lens material, make it ideal for landscaping applications that require submersible luminaires.

“We are excited about the possibilities the new Solas LED can provide,” explained Chalmit Marketing Manager Gareth Bruce. “The initial concept was to replace an existing emergency floodlight, the 261E. In this product the batteries were contained in a separate Ex e box. The use of LED’s and smart driver technology has allowed the complete solution to be contained within the luminaire enclosure. Not only is the Solas a more efficient, compact and price competitive replacement for the 261E, it has also created a host of new applications due to its increased flexibility.”
Traditionally, battery backup emergency floodlights have been reserved for specific platform abandonment applications. The development of quality long life LEDs is proving to have a much wider appeal. Such floodlights can now be used for continuous operation under normal lighting conditions. In contrast to high intensity discharge floods, the Solas is effectively maintenance free offering over sixty thousand hours of continuous operation. Another advantage of using LED technology is the efficient use of the light generated. The Solas has a high light output ratio resulting in over four thousand lumens with minimal losses. These levels can be compared to a seventy watt high pressure sodium (HPS) floodlight. However unlike HPS lamps the use of LED results in a much whiter light closer to that of natural daylight.
The luminaire is compliant with both ATEX and IEC Ex standards and is suitable for use in a wide range of ambient conditions from -55 degrees C to +55 degrees C. The universal voltage; 110V – 254V AC/DC 50/60Hz, makes the Solas a truly global product. An industrial, non-hazardous version is also available that provides the same levels of ingress protection (IP66/67) and maintenance free capability.
In addition to normal emergency operation where the battery engages when the mains power goes off, the Solas can also be fitted with a remote inhibition switch. Similar in function to the earlier 261E, this enables the LEDs to remain de-energised (Off) when the mains power fails. By operating the switch, the LEDs can be energised and run from the internal batteries. This gives instant illumination with one hundred percent output, unlike HID lamp technologies. The use of remote switching thus ensures battery duration is maximised.
This flexibility means the Solas is ideally suited to provide emergency escape lighting for example; during platform abandonment conditions, where the sea must be illuminated to ensure lifeboats can be safely launched.
Chalmit is part of Hubbell Harsh and Hazardous, a division of Hubbell Inc. The company has worldwide distribution and a network of offices strategically located to provide sales technical support to the oil and gas industry. Free Chalmlite software is available to help electrical and mechanical services designers optimise lighting intensity for safety and efficient working.

confession to make. I’m an environmentalist who’s been hoarding old incandescent light bulbs before they become illegal in January. But it was all unnecessary, so I learn. In 2007, Congress passed a law (signed by President George W. Bush) requiring that light bulbs be 70 percent more efficient by 2020. The tea party opposes all laws that force energy conservation on the public. (I like them.) My objection to the squiggly “energy savers” is purely aesthetic. I can’t stand the way they look.
While very efficient, LEDs produce heat that must be dissipated in lighting designs and retrofits, and this is often a challenge for engineers who do not have an extensive thermal management background. Wakefield's new heat sink extrusions save engineers the considerable time it can take to match the right heat sink with the right LED. Offering the maximum thermal management performance, they can accommodate top or side mounting with Bridgelux LEDs.

thousands on their energy bills after the introduction of the first LED powered street lights in Britain. Bath and North East Somerset Council are pioneering the move and have already installed the environmentally friendly lights at the Hicks Gate roundabout at the Bristol end of the Keynsham, Somerset.
The reason is simple: The new technologies promise brighter days for the bottom line. Light-emitting diodes or LEDS, in particular, are driving the lighting market as commercial, industrial and outdoor sectors — which make up 96 percent of the world's lighting energy use — continue to realize massive savings from the emerging technology.

LED bulbs. But this simple switch is not limited to the home. Some very important lights in South Bend are saving some serious money. The city has more than 205 intersections, add up all the individual lights and that is over 4000 bulbs. "The reason that we changed the bulbs is because incandescent bulbs are inefficient. By changing an incandescent bulb to an LED fixture, you save roughly 85 percent of the energy,” Rob Nichols said.

When I drove to the offices of a start-up called Switch Lighting last week, I wasn't expecting much. A company representative had promised to show me something amazing—an alternative light bulb that uses a fraction of the energy of a traditional incandescent bulb and lasts 20 times as long, but that plugs into a standard socket and produces the same warm, yellowish, comforting glow that we're all used to seeing when we flip the switch.
The HLMP-Lx75 and HLMP-Hx74/75 LED series offer a typical viewing angle of 40 by 100 degrees, while the HLMP-Ax74/75 LEDs offer 30 by 70 degrees. The wide typical viewing angles and the high luminous intensity of the LEDs deliver optimal performance for outdoor applications. The package epoxy of the LEDs contains UV inhibitor to reduce the effects of long-term exposure to direct sunlight, and the package also offer superior resistance to moisture, providing enhanced durability for outdoor environments. Avago provides design flexibility with the option of shipping tight color and intensity bins, up to 4 nm per bin for the new blue and green LEDs.
The new red AlInGaP LEDs are available at 626-nm dominant wavelength, and the new green InGaN and blue InGaN LEDs are available at 530-nm and 470-nm, respectively. The maximum luminous intensity at 20 mA of the new LEDs is as follows

gaining much interest. Typically, a small number of LEDs—between five and nine—are connected in series and a power supply has to convert the line voltage to a low voltage, typically tens of volts, at currents around 350 to 700 mA. There are a number of tradeoffs in determining how to best isolate the consumer from the line voltage. Isolation can be accomplished either in the power supply or in the mounting of the LEDs. In these lower-power designs, physical isolation of the LEDs is a common choice as it allows the use of a cheaper, non-isolated power supply.
