Electronic and thermal improvements bring advances to lighting technologies The Direction of Light

摘要

The desire to cut costs and reduce energy use has led both consumers and businesses to explore more efficient lighting options. By 2012, the United States will begin to implement the first phases of the efficiency standards mandated by the EISA (Energy Independence and Security Act) of 2007 and will begin to phase out the use of incandescent bulbs (Reference 1). In the short term, CFL (compact-fluorescent-light) bulbs will be the most common replacements for incandescents, and halogen bulbs will be a distant second. Manufacturers have also begun to deploy SSL (solid-state lighting) employing HB LEDs (high-brightness light-emitting diodes) in applications that can trade off SSL's premium price in exchange for efficiency and ruggedness.
