  • LED component with low RTH with dissociated electrical and thermal paths
    Patent number: 8921881
    Abstract: A component emitting light radiation comprising a vertical junction supported on a substrate, the face of the substrate opposite the face on which the junction is made is provided with at least one first conducting zone dedicated to electrical contact and a second conducting zone insulated from the substrate and from the first conducting zone, the second zone being dedicated to heat dissipation.
    Type: Grant
    Filed: March 22, 2013
    Date of Patent: December 30, 2014
    Assignee: Commissariat a l'Energie Atomique et aux Energies Alternatives
    Inventors: Adrien Gasse, Francois Levy
  • Light emitting diode component
    Patent number: 8866375
    Abstract: A light-emitting diode component includes a primary source, a conversion layer forming a secondary source configured for absorbing the primary radiation at least in part and emitting a secondary radiation, an encapsulation layer, situated between the primary and secondary sources. The light-emitting diode component also includes a reflection layer (i) situated between the encapsulation layer and the conversion layer and having a face in contact with the encapsulation layer so as to form an interface with the encapsulation layer, the reflection layer (i) and the encapsulation layer being configured so that the interface allows the primary radiation originating from the primary source to pass and reflects the secondary radiation toward the outside of the light emitting diode.
