This standard provides compatibility requirements when a forward phase cut dimmer is combined with one or more dimmable LED Light Engines (LLEs). An LLE comprises one or more LED modules, LED control gear (integral or remote), and a connection to the mains circuit. This includes both screw-in integrated LED lamps, as well as fixtures which contain separate LED drivers. NEMA SSL 7A-2013 is meant to reduce the testing burden by utilizing synthetic loads and waveform generators to represent LLEs and dimmers during testing.
Among other matters with LEDs, reliability has been an issue. Long life, unparalleled efficiency, brightness and durability are just some of the benefits that LED technology brings to the industry table and the contractor’s market basket. But while the $2.5-plus billion LED lamp industry continues to progress along its rapid growth trajectory and distinctive path as the future of lighting, it remains plagued by a number of issues that currently impair its viability in a variety of key applications. Experts discuss some of the issues that LEDs continue to face at this stage of their evolution as well as tips to help contractors navigate through the sometimes murky waters of LED technology.
While integrated LED replacement lamps are designed around conventional lamp sockets, these interfaces are impractical for LED lighting fixtures, the majority of which are designed as highly integrated devices. This allows the product to be optimized around the technology but means the light source and control gear (driver/power supply) cannot be easily replaced. Some products are designed around components that are replaceable but only with major disassembly. A growing number of fixtures are entering the market that offer replaceable components, but the connections are proprietary, providing durability but not choice. Enter Zhaga, an industry consortium founded in 2010 around the goal of providing interchangeability of LED light sources made by different manufacturers. The organization now has more than 270 companies and organizations participating, including big names such as Acuity Brands, Cooper, Cree, GE, Osram Sylvania, Philips and Zumtobel.
With the increased concern for facility energy conservation in recent years, much attention has been focused on lighting energy consumption and the methods for reducing it. Lighting has a profound effects on worker productivity, as well as important aesthetic qualities. With this understanding in mind, this book presents an introduction to effective lighting design, and an examination of energy efficiency measures which can be implemented while simultaneously maintaining the required quality of illumination. Topics include lighting energy management, selection of lamps, task lighting, lighting design, lighting control, use of reflectors, ballast selection, natural daylighting, wireless lighting control, and case studies.
