Abstract

Bei einer Beleuchtungsanordnung (1) mit mindestens einer Lichtquelle (2), insbesondere einer LED, Erfassungsmitteln (10, 20) zum Erfassen des von der Lichtquelle (2) abgegebenen Lichts sowie einer Steuereinrichtung (5) zum Ansteuern der Lichtquelle (2) in Abhängigkeit von durch die Erfassungsmittel (10) übermittelten Informationen sind die Erfassungsmittel (10, 20) bzw. ein Teil davon zum Erfassen des von der Lichtquelle (2) abgegebenen Lichts vorübergehend in den zur Lichtabgabe der Anordnung vorgesehenen Strahlengang (7) einbringbar.

Figure imgaf001
In a lighting arrangement (1) with at least one light source (2), in particular an LED, detection means (10, 20) for detecting the light emitted by the light source (2) and a control device (5) for controlling the light source (2) in dependence of information transmitted by the detecting means (10), the detecting means (10, 20) or a part thereof for detecting the light emitted from the light source (2) is temporarily introduced into the optical path (7) provided for the light emission of the device.
