  • Lighting control circuit
    Patent number: 11102865
    Abstract: A lighting control circuit includes: a light-emitting element which includes a first terminal and a second terminal; a first shunt resistance element which is connected in parallel to the light-emitting element between the first terminal and the second terminal; and a control circuit which turns, into a conducting state, a first current path extending between the first terminal and the second terminal via the first shunt resistance element when a potential difference between the first terminal and the second terminal is greater than a first threshold value and turns, into a non-conducting state, the first current path when the potential difference is smaller than the first threshold value.
