Light-emitting diodes brighten new HDTVs

LED LCD TVs have joined the parade of garden-variety LCD and plasma TVs on the shelves of retailers. But before you say “Not another acronym!” consider the energy savings and enhanced picture of this new breed of  TV.

Change your light bulb, flatter your face

Every time I’m on the TODAY Show, I say hi to Matt, Ann, Al and Meredith, I shake hands with my producer, and then I bow down and give thanks to the man who is by far the most important person at the show: Howie Strawbridge. Who the heck is Howie? He’s the TODAY lighting director. Why do I bow down to him? Well, for one thing, he’s very nice. But while my TODAY pals are fantastic to work with on camera and my producer keeps me out of trouble, it’s Howie who makes me look, um, “good” at 7:00 in the morning.

LEDs Move Into Home Lighting Market

Joey Nicotera's fascination with multicolored light bulbs bordered on obsession when he was a teenager. He framed posters in lights and decorated his own Christmas tree. When he couldn't find a color bulb he wanted, he got paint cans from the basement and made some himself, bathing his second-story bedroom in an eerie glow.

Light-emitting diodes save energy. In terms of their light output, however, they have so far been unable to compete with light bulbs. A new, low-priced optical component is set to change that situation: It concentrates the light and directs it precisely to where it is needed.
