  • Light-emitting device
    Patent number: 9269862
    Abstract: A light-emitting device includes: a Distributed Bragg reflector comprising alternate first semiconductor layers and second semiconductor layers, wherein each first semiconductor layer comprises a low-refractive-index part having a depth; and a light-emitting semiconductor stack associated with the Distributed Bragg reflector; wherein the depths of the low-refractive-index parts of the first semiconductor layers are gradually changed in a direction toward the light-emitting semiconductor stack.
    Type: Grant
    Filed: November 29, 2013
    Date of Patent: February 23, 2016
    Assignee: EPISTAR CORPORATION
    Inventors: Wu-Tsung Lo, Yu-Chih Yang, Chien-Ming Wu, Kai-Yi Hong

  • Electromagnetic wave gathering device and solar cell module having the same
    Patent number: 8755665
    Abstract: An electromagnetic wave gathering device includes a pillared electromagnetic waveguide body and a reflective structure. The reflective structure is located at about an axis of the pillared electromagnetic waveguide body. The reflective structure comprises a plurality of bicone reflective units. Each of the reflective units has a first reflective surface. The electromagnetic wave gathering device may have a smaller volume and is handy for use.
