ILLUMINATION SYSTEM

An illumination system (1) comprises a plurality of lamps (11, 12, 13) for generating light (R, G, B) with mutually different colors; in an embodiment, the lamps are fluorescent lamps. A sensing system (50) comprising a color sensor (51) provides a sensor output signal (Ss) that indicates the color...

Zusammenfassung:	An illumination system (1) comprises a plurality of lamps (11, 12, 13) for generating light (R, G, B) with mutually different colors; in an embodiment, the lamps are fluorescent lamps. A sensing system (50) comprising a color sensor (51) provides a sensor output signal (Ss) that indicates the color of the light received by the color sensor. The sensing system comprises a light guide arrangement (60) interposed between the lamps and the sensor, which is arranged in a service room (74) shielded from ambient light. Each light guide captures light from one lamp only, and the sensor receives a mixture of the captured lights. The color sensor and light guide are used in a feedback system that corrects for tolerances, lamp aging, ambient temperature etc.
