Sapphire Industry Watch – October 10

  • Physics Nobel Prize goes to scientists who perfected LED light – CNN World: The 2014 Nobel Prize for Physics has been awarded jointly to three scientists for inventing LEDs, a source that now lights up everything from homes to streetlights to smartphones. American Shuji Nakamura along with Japan’s Isamu Akasaki and Horoshi Amano revolutionized lighting technology 20 years ago when they created blue LEDs, which when coupled with red and green LEDs produces white light.
  • Shipments of LEDs for residential applications to grow from 81 million in 2014 to 1.1bn units by 2023 – Semiconductor Today:  According to a report from Navigant Research, annual shipments of LEDs for residential applications are expected to grow from 81 million in 2014 to 1.1 billion units by 2023. As prices of LEDs continue to fall, the market for LED light fixtures and lamps is set to explode in the residential sector. In addition, advances in connected lighting shows promise to dramatically affect the way people will interact with lighting in their homes.
  • James Dyson’s son built a super-efficient LED light that will last 40 years – Digital Trends: Inventor/designer Jake Dyson, son of James Dyson, has created an LED light bulb that can run for an estimated 180,000 hours- approximately 40 years of shining at full brightness for 12 hours each day. The bulb, named the “Ariel” suspension light, is named after the Ariel 1 satellite and incorporates the same heat pipe cooling technology that was initially developed to siphon heat away from a satellite’s microprocessors.
  • Kyocera’s sapphire screen is tougher than we expected – Engadget: The Verizon-exclusive Kyocera Brigadier is armed with a 4.5-inch sapphire screen and to demonstrate just how scratch-proof it is, Engadget reporter Brad Molen put the screen through rigorous testing. After scraping several sharp objects against the screen (knives, keys, scissors, screwdriver) and performing drop tests, it is clear that the sapphire screen is unscratched and in one piece.
  • Dubai Skyscrapers The Inspiration of 2015 Cadillac Escalade LED Lights? – GM Authority: According to Cadillac, the 2015 Escalade’s designers looked at both classic Cadillac models and modern skyscrapers, such as those in Dubai, for inspiration when working on the exterior lighting of the vehicle. 142 LEDs make up the exterior lighting of the car which is accentuated with an edge-lit blade technology, giving the visual of lights floating in space.
