  • Method and apparatus for operating a semiconductor light source
    Patent number: 11019696
    Abstract: A method and apparatus for operating a semiconductor light source is presented. In particular there is a current regulator for regulating a current flowing through a light emitting diode device. The current regulator includes a first switch for receiving a first current flowing through the semiconductor light source and a control circuit coupled to the first switch and adapted to provide a second current proportional to the first current. The current regulator is adapted to regulate the first current using the second current.
