    OUTDOOR LIGHTINGField trials of LED outdoor lighting demonstrate benefits to potential adopters The LightSavers consortium of cities is undertaking an extensive and coordinated series of trials of LED outdoor lighting products, with a view to persuading the relevant authorities to adopt the technology, writes PHILIP JESSUP.

    FABRICATIONLED industry requires versatile equipment to suit different needs Collaboration with equipment suppliers can help LED manufacturers to get equipment specifically designed or adapted for their needs, and can also result in shorter development cycles for new products and process flows, according to Thomas Uhrmann and Thorsten Matthias.




    CONTROLS
    LED lighting must work with legacy dimming technologies
    To achieve broad market success, LED lighting manufacturers must deliver products that offer dimming capability that is at least equivalent to incandescent lighting, and SSL luminaire design must support legacy dimming controls, explains David Cooper.

    THERMAL Active cooling can boost lumen output in LED lighting Active cooling technology can offer thermal capabilities that are superior to passive heat sinks and can raise lumen output and extend LED life in solid-state lighting, says Ryan Ahearn.
    OUTDOOR LIGHTINGRaleigh LED lighting projects demonstrate durability and savings Beginning in 2007, Raleigh, North Carolina, was among the first cities to install LED-based lighting, and has demonstrated energy and maintenance savings over a long term with better-than-expected lumen maintenance, says MAURY WRIGHT.
    OLEDs Is the lighting industry now in the mood for OLEDs? OLEDs are evolving as complementary sources for indoor lighting, says Verbatim’s JEANINE CHROBAK-KANDO, who provides an overview of technology, desirable characteristics and the current status of today’s OLED lighting products.

    DESIGN FORUMCoordinated circuit protection enhances AC-LED luminaires and lamps Properly-deployed components can protect AC-LED-based lighting-system designs from over-voltage, over-current, and over-temperature conditions while meeting safety and performance standards, say Barry Brents and David Neal.

    LAST WORDLED lighting allows companies to go green and save money Green initiatives are certainly worthwhile given the positive impact on the environment, and LED lighting is one green technology that can also save companies and individuals money, explains Ron Lusk, CEO of Lumetech Group.
