  • Circuit arrangement for an LED light source
    Patent number: 9516711
    Abstract: A light-emitting diode module is provided that includes a housing and a printed circuit board, which is connected to a light-emitting diode and which has an LED driver, a control module, and a circuit arrangement. The circuit arrangement has a DC/DC converter and a bypass connected in parallel to the DC/DC converter. The bypass is activatable by a comparator circuit. The comparator circuit is arranged between an input of the circuit arrangement and the DC/DC converter and detects the level of an input voltage of the circuit arrangement and compares it with a first and second threshold value. The comparator circuit activates the bypass when the input voltage is below the first threshold value and deactivates the bypass when the second threshold value is exceeded.
