2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED posting says that the 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, the inventors of the blue LED. When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors →

I needed to replace few burned 50W GU10 halogen bulbs with LEDs. A standard 50W halogen lamp outputs 400 lumens so I needed to find a reasonably LED bulb that gives around the same light output. I could live with slightly less, but not too much less. I found suitable looking product AIRAM LED 4W →

LEDs Bring New Light to Car-to-Car Communication – IEEE Spectrum http://spectrum.ieee.org/transportation/advanced-cars/leds-bring-new-light-to-car-to-car-communication This is quite interesting idea. It combines tho things I have written earlier: communicating LED lamps and car electronics. Posted from WordPress for Android →

I had to replace some 50W GU10 halogen bulbs. I though it could be time to check if it would be reasonable to go to use LED bulbs. I did a year or so similar checking, and at this time it did not feel reasonable because reasonably prices LED bulbs gave considerably less lights out →
