  • Quantum dot chip on board
    Patent number: 9634198
    Abstract: Quantum dots used to modify the spectral output of an LED exhibit less of a performance decrease (due to increased temperature) when incorporated in a chip on board (COB) as compared to conventional LED packages. A ceramic ring may be used to shield the quantum dots from the heat associated with connecting electrical leads to pads on the COB. The upper surface of the ceramic ring may be sealed with a glass disk or other transparent material.
    Type: Grant
    Filed: January 23, 2015
    Date of Patent: April 25, 2017
    Assignee: Nanoco Technologies Ltd.
    Inventor: Dale Needham
  • Multi-wavelength-emitting lens to reduce blending of light over long distances
    Patent number: 9255671
    Abstract: A lamp for safety signalling is disclosed. The lamp uses quantum dot phosphors to down-convert light from a primary light source and provide red or green light.
    Type: Grant
