  • Patent number: 9190586
    Abstract: A semiconductor light-emitting device includes at least one light-emitting chip. The light-emitting chip includes plural light-emitting units, which are electrically coupled to each other in series, in parallel or in series-parallel combination; a first-type electrode electrically coupled to an external power source, the first-type electrode being disposed on one of the light-emitting units; a second-type electrode disposed on another of the light-emitting units; and a tapped point for electrically coupling at least one of the light-emitting units to an electronic component.
    Type: Grant
    Filed: April 12, 2013
    Date of Patent: November 17, 2015
    Assignee: PHOSTEK, INC.
    Inventors: Shih Tsun Yang, Yuan-Hsiao Chang, Jhih-Sin Hong

  • Publication number: 20140055049
    Abstract: An illuminating device includes at least one light-emitting source. The light-emitting source includes a substrate; at least one light-emitting chip disposed on the substrate; and at least one constant-current component electrically coupled to the light-emitting chip. The light-emitting chip includes multiple light-emitting units that are electrically coupled in series, in parallel, or in series-parallel; a first-type electrode, disposed on at least one of the light-emitting units, for electrically coupling to a central DC power source; a second-type electrode disposed on at least one light-emitting unit different from the one, on which the first-type electrode is disposed; and a tapped point configured for electrically coupling at least one of the light-emitting units to the constant-current component.
