ENERGY-EFFICIENT LIGHTS TO GAIN FROM INCANDESCENT BAN

摘要

THE 100-YEAR-LONG REIGN OF THE INCANDESCENT LIGHT BULB IS ABOUT TO END. RATHER THAN BEMOANING ITS DEATH, LIGHTING-CIRCUIT DESIGNERS WOULD DO WELL TO SEETHE OPPORTUNITY IN OFFERING A LIGHT WITH INSTANT-ON.THAT DIMS WITHOUT FLICKER, AND THAT IS RELIABLE AND COST-EFFECTIVE. The Energy Independence and Security Act of 2007 dictates the phase-out of the incandescent light bulb starting in 2012 (Reference 1). The bill does not specifically ban incandescent lights: You will still be able to buy any incandescent light that can meet the act's efficacy specification of a 25% improvement in incandescent-light output. The lights are notoriously poor producers of usable light, however. They lose 96% of the power they use to heat; hence, Hasbro uses them as the heating element in the Easy-Bake toy oven. So far, no one has discovered a cost-effective way of coaxing more light and less heat from incandescent lights.
