Abstract

An illumination device is provided. The illumination device includes a light source and a current path configured to transport a supply current to the light source. Further, the illumination device includes a sensor configured to contactlessly measure a current strength of the supply current in the current path and to output a measurement signal indicative of the measured current strength. The illumination device additionally includes processing circuitry coupled to the sensor and configured to determine the optical output power of the light source based on the measured current strength indicated by the measurement signal.
