    What's Inside Those LED Bulbs, Anyway?

    Generally you see a light bulb and you think “yep, a light bulb.” But when you see an LED bulb, you might pause and say “wait, isn’t there more to an LED than there is to incandescents?” And you’d be right to pause.

    POV displays for Ping Pong (and how to make your own)

    Recently, UK design studio Troika came up with a concept Ping Pong paddle (they call them bats - silly englishmen) that that uses LEDs to show the word "PING" or "PONG" as the paddle moves through the air. Pretty cool idea, but what if you could do the same thing for regular objects in your home? Maybe a door that shows "SLAM" as you close it? Read More

    Duroflash LED road lights effectively replace flares

    Forget about roadside flares. You don't need them anymore now that there's a gadget that can do the same thing. The Duroflash LEDs are simple little lights that do the same job but better. They're waterproof, super bright, available in several colors, and can support up to 20,000 lbs.

  • New LED lightbulb will last 17 years

    New LED lightbulb will last 17 years

    CFL bulbs are great, but the mercury they use can be harmful. LEDs don't use mercury, but the technology is still pretty rough, and it's tough to get something that resembles a normal lightbulb from them. There's been a couple of examples of how LED light can be used as a replacement for normal lighting, but nothing that's really practical. Read More

    Better LCD TVs? New CCFL backlights to compete with LEDs

    Japan's Sanken Electric has developed a new type of cold cathode fluorescent lamp (CCFL) backlight for LCD TVs that's as power-efficient as LED backlights but is supposedly up to 60% cheaper to mass-produce. Approximately 90% of all LCD TVs currently on the market have CCFL backlights. A 32-inch LCD TV usually requires six CCFL tubes, but Sanken says their new lamps are so efficient that only two… Read More

    Acriche unveils first 100 lm/W AC LED light

    I like the idea of LED lights, as I'm sure you do, too. Like you, I dislike the inefficiencies of incandescent bulbs, although I like the bright, warm light they produce. Like you, I like the power efficiency of CFL bulbs, although I dislike all that nasty mercury inside them. LED lights look like a big win, except, of course, for the fact that the light is either too diffuse to be useful, or too… Read More

    Now blinking LEDs can transmit information to cell phones via light

    I'm not really sure if this is good or bad news for end consumers, but a couple of Japanese companies have developed a technology that makes it possible to transmit information from blinking LEDs fixed on advertisements to cell phones - using only light. The companies involved in the development include some big names such as Toshiba or NEC. With this new system, Japanese cell phone users don't… Read More
