  • Driver circuit for an led
    Patent number: 5742133
    Abstract: A driver circuit for an LED includes a switch device being connected to the LED, being controlled by an input signal, and having a current source circuit. The switch device short-circuits the LED after a transition to a first switching state, and the switch device supplies the LED from the current source circuit after a transition to a second switching state, causing a higher current to flow initially and causing a lesser current to flow after a predetermined time period has elapsed.
