  • Semiconductor light emitting device
    Patent number: 8704249
    Abstract: A semiconductor light emitting device includes: a first conductivity type semiconductor layer; a light emission layer; a second conductivity type semiconductor layer; a conductive portion of a first polarity electrically connected to the first conductivity type semiconductor layer; and a conductive portion of a second polarity electrically connected to the second conductivity type semiconductor layer. At least one of the conductive portion of the first polarity and the conductive portion of the second polarity includes a plurality of separated electrode portions arranged on a light emission surface. The closer the positions of the separated electrode portions are to a center point of the light emission surface, the separated electrode portions are provided sparsely, and the farther the positions of the separated electrode portions are from a center point of the light emission surface, the separated electrode portions are provided densely.
