  • Illumination light control system and switching unit
    Patent number: 10499483
    Abstract: Provided is a technique that facilitates control of a navigation light which uses light-emitting diodes for a light source. This navigation light control system is provided with: a navigation light that has a light source for which a light-emitting diode is used; a power supply unit that supplies power to the navigation light; and a control device that controls lighting of the navigation light, wherein the control device is provided with a light source circuit that supplies the power received from the power supply unit to the light source, and a determination unit that determines failure of the light source on the basis of the value of the current flowing through a resistor connected to the light source circuit.
    Type: Grant
    Filed: October 26, 2017
    Date of Patent: December 3, 2019
    Assignee: OMRON Corporation
    Inventors: Gen Yoneda, Naoki Motoyama
