LED Lighting Design Guide 2015 Littelfuse LED Lighting Design Guide www.littelfuse.com Over the next couple of years, LED lighting adoption will be highest in retail accent lighting and cold storage followed by street, highway, parking lot and public structure illumination, and niche applications in commercial building lighting. Street lighting energy efficiency measures have been initiated by many local cities and municipalities around the world seeking to replace high pressure sodium (HPS) lamps with LED lights. For parking lots and parking garages, HPS, metal halides and fluorescents are the main targets for replacement. The United States is leading the way for establishing uniform performance and safety standards for certain indoor commercial lighting as well as roadway, parking lot and garage illumination. The EPA's Energy Star specifications apply to LED replacement bulbs for residential and certain commercial applications. The US Dept of Energy's Municipal Solid State Street Lighting Consortium's LED Roadway model spec, and the Commercial Building Energy Alliance Parking Lot and Structure Outdoor LED lighting performance spec are examples of important documents released in late 2011 and early 2012 respectively. A Littelfuse video, Circuit Protection and Reliability Solutions for the LED Lighting Market , provides an overview of global standards for circuit protection of LED lighting. Littelfuse describes the market and circuit protection needed for LED lighting. To view the video, visit: https://vimeo.com/50692101 Introduction (continued) 4
