March 22nd, 2008A Really Bright Idea
Californian company Luxim has developed a new ‘LIFI’ plasma light bulb. It’s not much bigger than a Tic-Tac, according to a report on CNET News, yet it gives off the same amount of light as a streetlamp. The bulb is driven by a RF generator, which creates a high frequency field around it that vaporises a mixture of gasses that changes to a plasma. The result is an intense light, available in a spectrum of colours. The bulbs are long lasting – up to five times longer than conventional lamps and they’re energy efficient too. Applications include street and stage lighting, video projectors, endoscopy and numerous industrial processes.
