LEDS set to dominate lighting applications in the future
Technology Review reports on the increasing use of LEDS and the consequent decline in popularity of the traditional light bulb. ‘LEDs, which are small chips usually encased in a glass dome the size of a matchstick head, have been in use in electronics for decades to indicate, for example, whether a VCR is on or off. Those LEDs were usually red or green, but a scientific breakthrough in the 1990s paved the way for the production of LEDs that produce white light. Because they use less power than standard incandescent bulbs, white LEDs have become common in flashlights.’
