Acuity demonstrated dazzling OLED products at Lightfair including the Winona Modelo fixture designed for retail and hospitality applications, but the technology still trails LEDs in efficacy and was relatively scarce at the LED-dominated tradeshow (see page 34).

CONFERENCES
Executives chart future of LEDs and lighting at Lightfair
Tunable lighting, networks and controls, thermal and optics advancements, the evolution of the LED, and business strategy were top-of-mind subjects for key industry executives at Lightfair, reports Maury Wright.

LIGHTFAIR PRODUCTS Tunable LED lighting and controls are stars of show Solid-state lighting (SSL) products again dominated the exhibit floor at Lightfair International, with the most compelling demonstrations involving tunable LED white and color lighting and adaptive controls. Indeed, SSL retrofit lamps took a back seat at Lightfair International (LFI) 2013, with the emphasis on more functionality such as tunable features in LED-based integral luminaires. The exhibits revealed more evolution in form factor and functionality and little lingering concern as to whether LEDs are the best light sources for general illumination applications.

CASE STUDY
Field evaluations of LED lighting show benefits beyond reduced energy usage
Industry-specific field demonstrations will play an essential role in assessing the benefits of solid-state lighting, especially when looking at factors that go beyond energy savings, say Martha Carney and Howard Wolfman.

SEMICON WEST PREVIEW Semicon session will examine next steps for HB LED manufacturing Integration of more features on chip and transition to new materials technologies are two potential paths that LED manufacturers will pursue in attempts to lower LED-component or SSL-system cost, reports Paula Doe.

DESIGN FORUM Proper driver design optimizes LED lighting Since LEDs don't inherently flicker, careful approaches to the driver electronics enable SSL products that can dim smoothly and eliminate visible flicker, writes Robbie Paul.

LAST WORD
Integral LED luminaires outperform lamps
Thor Scordelis and Steve Landau, manager of global product marketing and director of marketing communications, respectively, of Xicato argue that while the time is right for LEDs, demanding lighting applications fare better with purpose-built luminaires rather than retrofit lamps.
