Physics Nobel Prize to Inventors of Blue Diode Light Source

LED

|

Two Japanese scientists and a Japanese-born American won the Nobel Prize in physics on Tuesday for inventing blue light-emitting diodes, a breakthrough that has spurred the development of LED technology to light up homes, computer screens and smartphones worldwide.

Isamu Akasaki, Hiroshi Amano and naturalized U.S. citizen Shuji Nakamura revolutionized lighting technology two decades ago when they came up with a long-elusive component of the white LED lights that in countless applications today have replaced less efficient incandescent and fluorescent lights.

  1. Damn. I thought it was going to be an Obama sweep.

    1. Only in the Peace Prize category. Just the things he’s really good at. I’m sure he’ll pick up a Nobel Prize in Physics after he’s done his stint as World Leader at the UN from 2016 to 2026.

  2. I hate blue LED’s on everything!!! They light up the room and mess up my night vision.

  3. “Poor Nakamura’s” story is a good libertarian IP read. The Blue-LED brought about the revolution in LED lighting and high-density optical storage. Nichia Corp. paid Nakamura a nominal $100 bonus, and dominated/crippled the market;

    1. FTA:Researchers at Japanese companies usually sign a contract that gives all rights to innovations to their employers, and Nakamura said he signed such a contract when he joined Nichia.

      He agreed that the company got all the patents when he signed the contract. I don’t see any issue here except contractual obligations. What am I missing?

      1. What am I missing?

        Uh… [In 2004] a Tokyo court ordered Nichia to pay him a record 20 billion yen ($185 million). The company appealed and Nakamura settled for about $8 million.

        Not to mention your rather selective reading of the strictly personal side of the issue. Nichia squashed innovation WRT to the Blue LED. It used IP law to harass unrelated businesses (and antagonize the careers of former scientists). Counter-litigation followed and the settlements effectively nullified the IP.

        Seems like a lot of work to ‘own’ something which can’t actually be held/consumed.

        1. Stupid link; http://www.reuters.com/article…..MJ20141007

        2. Seems like a lot of work to ‘own’ something which can’t actually be held/consumed.

          So he doesn’t deserve jack shit, right? Only individuals can hold IP’s not corporations? His personal involvement is meaningless but you just wanted to rant against IP?

          I guess what I am missing are the voices in your head.

  4. I spotted this blog post from American Thinker about the unintended consequences of the LED lights http://www.americanthinker.com…..nobel.html

    1. The three scientists responsible for allowing governments to ban most incandescent light bulbs by inventing the LED have won the Nobel Prize in physics.

      That’s an awful lot of bullshit to swallow in one sentence.
