資料介紹

?

It is estimated by the International Energy Agency that more than 19% of electrical energy demand?
globally is used for lighting. As a result, there has been significant effort around the globe in replacing?
in-efficient incandescent light sources with higher efficiency solutions. Much of the focus in curbing?
this demand at the consumer level has been in programs to drive adoption of compact fluorescent lamps?
(CFL). The choice of using CFLs is not without consequence; each bulb contains mercury which, when?
not disposed of properly, ends up in landfills. ?Moreover, the form factor is not ideal for all lighting?
applications. An alternative which has been gaining significant attention is phosphor converted “white”?
LEDs. LED lumen output and efficacy – the measure of lumen output versus input power - continues to?
make significant progress year over year while, at the same time, the cost in terms of lumen/$ is falling.?
Beyond energy savings, High brightness LEDs can have lifetimes of greater than 50,000 hours when?
properly designed and operated which eliminates the cost of replacing bulbs.?
?
An off-the-shelf halogen desk lamp was used as the basis for a demonstration of the real world?
performance of today’s latest production LED light sources. ?A Cree XLAMP(R) MC-E LED was used?
as the light source. ?This product incorporates 4 LEDs in a single compact package which is ideal for?
directed light applications such as MR-16 and Portable Task Lamps. ?The original lamp was?
characterized before and after modification to highlight the real world performance differences. ?
?
The DoE ENERGY STAR Standard for Solid State Lighting Luminaires (Version 1.1 - 12/19/08)?
includes requirements for a minimum power factor (PF) of 0.7 for portable residential desk lamps. ?
Typical LED drivers at this power level normally have a PF of 0.5-0.6 which falls below the?
requirements. ?The solution presented here has been specifically designed to exceed the residential?
ENERGY STAR(R) PF requirements without the addition of extra circuitry.?
