Breakthrough In LED Construction Increases Efficiency By 57 Percent

Posted by Soulskill on from the more-bright-ideas dept.

Zothecula writes: With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent.

    Your equipment will now have 57% brighter indicator LEDs on the front to burn your retinas at night!

      In Low light environments you really need red LED's
      Sure Red LEDs are old. But for low lights your eyes don't adjust as much to red lights.

      This is quite funny. Though refrained taping my eyes shut (and I'm not a vampire), I did just last night, go around my room and put pieces of black electrical tape over every LED light I could find sans the clock (which dims in the darkness thank goodness). It's amazing just how sensitive your eyes are to light pollution at night. Every power bar I have has a glowing light of some kind. One even has two. I have a wireless extender that has several LEDs on it. Then there's the TV, the TV cable box, a heater...everything got the electrical tape band aid treatment. I even put a black screen wipe over my cell phone in it's charger cradle that likes to let me know it's charged by beaming me in the face with green light. Tablets get charged with their cases closed and the laptop charger goes face down into the carpet. When I charge my electric shaver or toothbrush, they get turned upside down to shine their light into themselves. Made a HUGE difference to the point where I have to feel my way around if I shut off the lights too soon.

      I've had to get obsessive compulsive about this just so I can get a decent sleep...but it's worth it!

    Just saying.

    The main barrier to large scale consumer and commercial adoption of LEDs is cost per unit.

    That said, good news!

    There's a big difference between "LEDs" and "Organic LEDs". To the best of my knowledge, organic LEDs aren't used for "lighting".
