Semiconductor component for supplying power to semiconductor light source of lighting device, has current output provided for direct electrical connection with light source, and component formed as integrated switching circuit

摘要

The component (2) has a constant current source (6) for supplying mean current of 40 milli Ampere, and a current output (4) provided for a direct electrical connection with a semiconductor light source (5) i.e. LED, where the component is formed as an integrated switching circuit. The component processes a serial input signal at a data input interface (1), where the input signal comprises a control signal that controls the semiconductor light source. A gamma correction unit is provided to extend the control signal up to 12 bits.
