Project Lighting - April 2008 - (Page 18) FeAtURe leD lighting needs Smarts to Be competitive efficient solid-state lighting with smart controls may soon reach mass adoption By lucio Di jasio | microchip technology | chandler, az | www.microchip.com Contents Viewpoint Selecting HBLED Drivers for Lighting Apps Simulation Technique for Optimizing White-LED Design An Analytical Approach to Cooling HBLEDs Lighting News he introduction of new and ever-moreenergy-efficient and powerful LED solid-state lighting (SSL) solutions has recently accelerated so much that some believe a major revolution of the entire lighting market is imminent. In many vertical applications, such as in signaling, automotive, and LCD TV backlighting, LEDs are becoming an irresistible alternative. Yet, the next obvious step—wide adoption in general lighting applications—cannot be taken for granted and may lag the vertical applications by a significant number of years. No doubt the cost and energy efficiency of SSL solutions 18 | Project lighting | aPr 08 T continues to improve rapidly and should soon reach the critical thresholds for mass adoption of the technology— some say it will be in 2007, some in 2008, some are only willing to bet on 2010. ssL in gEnEraL Lighting Home Page Product Training Module Online Ordering Suppliers Catalog The problem with making this transition is the market’s size, and consequently its inertia. The need for backward compatibility is perhaps the biggest challenge. Thermal management, voltage conversion, and color management are some of the fundamental problems that need to be addressed.
