  • Light emitting device, light emitting device unit, and method for fabricating light emitting device
    Patent number: 8575630
    Abstract: In a light emitting device, a light emitting device unit, and a method for fabricating a light emitting device according to an embodiment of the present invention, a light emitting device (100) includes a substrate (131), a semiconductor light emitting element (121) disposed on the substrate (131), and a resistor (122) coupled to the semiconductor light emitting element (121). The resistor (122) is coupled in parallel to the semiconductor light emitting element (121). The resistor (122) has a resistance set at such a value that when a light emitting operation voltage for causing light emission of the semiconductor light emitting element (121) is applied to the semiconductor light emitting element (121), a current flowing through the resistor (122) is equal to or less than one-fiftieth of a current flowing through the semiconductor light emitting element (121).
