摘要

Huge advances in LED technology over the past decade are translating into power savings, increased functionality and low maintenance costs. There have been big advances in LED technology over the last 10 years. "In 2000, white LED technology in the form of low-power signal emitters was only suitable for indication purposes or when grouped in a high-density array used as localised spotlights for applications such as reading lights," says Martin Ramsden, engineering manager at LPA Excil Electronics. "However, the introduction of high-brightness power LEDs in the early 2000s opened up the opportunity to replace conventional lighting technologies. With efficacy figures low at only 10 lm/W, dramatic power savings were not possible, but this new technology was significantly more reliable, At this efficacy level LEDs became a suitable replacement for halogen lamps for use as reading lights and supplementary downlights."
