    CONFERENCESStrategies in Light Europe addresses market adoption of LED lighting Part 1 of our report from the 2010 Strategies in Light Europe conference describes the activities of the European lighting industry, the rise of LED modules, and how LED lighting is shaping the future of light. TIM WHITAKER reports.


    LIGHTING: INDUSTRY STANDARDS
    LED lighting at the crossroads: country road or expressway?
    The LED lighting industry faces five major roadblocks, but if these can be overcome then the market will be able to accelerate rapidly, say FLORIAN WUNDERLICH, DOMINIK WEE and OLIVER VOGLER.

    STANDARDS UPDATE Non-directional luminaires require new testing procedures for LED light engines In his latest column on standards, JIANZHONG JIAO explains why changes to the Energy Star program will require new standardized procedures to evaluate the performance of LED light engines.

    STANDARDS: PRODUCT SAFETY LED product safety standard requires ongoing updates The UL 8750 product-safety standard has established a set of requirements for LED-based lighting products and the components needed to operate them. However, maintaining the standard during this period of rapid technological advancement is a daunting task, says TOM BLEWITT.


    NETWORK CONTROLS
    Networks layers pave the way to adaptive lighting controls
    Adaptive lighting control systems will be key to maximizing the energy efficiency of SSL, and network technology will form the foundation for such intelligent lighting systems, says Maury Wright.


    CONTROLS: INTELLIGENT LIGHTING SYSTEMS
    Intelligent lighting systems drive radical energy efficiency
    LED-based SSL can deliver significant energy savings relative to legacy light sources. And as Brian Chemel describes, the savings are compounded substantially with the addition of controls, resulting in an intelligent lighting system.

    ACQUISITIONS Merger of measurement companies brings integrating-sphere expertise under one roof Labsphere and SphereOptics, two US-based LED metrology companies, merged earlier this year and are now operating as part of Halma, a holding company that is eyeing further acquisitions, as KEVIN CHITTIM and DAVID LEIGHTY explain.

    DESIGN FORUM Thermal protection in LED driver circuit boosts reliability Despite an efficiency advantage over other light sources, LEDs can still suffer reliability issues if all parts of the lighting system, including the driver, aren’t properly protected from over-temperature situations, says STEVE ROBERTS.



    LIGHTING: COMPATIBILITY
    System compatibility testing improves reliability of LED lighting devices and systems
    In the second article in his series on compatibility and reliability, PHILIP KEEBLER explains how the concept of system compatibility was developed and how it applies to today’s electronic lighting products.
