The Future of Lighting

James Holloway, writing for Ars Technica:

"More tantalizing still is the prospect that the boundary between lighting technology and display technology may cease to exist. News headlines, share prices, real time weather data, and TV pictures could all be displayed on OLED lightwalls. Transparent OLEDs could overlay windows, letting in daylight by day and becoming warm, glowing electric lights by night. And you'd know it was time to knock off work if the entire west wall of your office dynamically displayed a photorealistic artificial sunset."

Ars has a two-page, fascinating article on current lighting technologies. There's apparently a Moore's Law for lighting, called Haitz's Law, and its claim is similar: LED lumen output doubles every three years, and costs drop by a factor of ten every decade. In short, the portent of the paragraph above will happen in the next ten years. Can't wait.
