A luminous means comprising a substrate having a first main surface, to which a first electrode is applied, a second electrode, an organic layer stack within an active region of the substrate between the first and the second electrode, wherein the organic layer stack comprises at least one organic layer which is suitable for generating light, and at least one reflective element, which is formed along a main plane of the luminous means, wherein the luminous means has two operating states, such that the luminous means is an illumination source in a first operating state and the luminous means is a mirror in a second operating state.

Organic lighting device and lighting equipment

A glazing comprising a luminous means with a substrate having a first main surface, to which a first electrode is applied, a second electrode, and an organic layer stack within an active region of the substrate between the first and the second electrode, wherein the organic layer stack comprises at least one organic layer which is suitable for generating light, wherein the luminous means is arranged between two glass plates of the glazing of a window. Also, storage furniture is disclosed comprising a storage element shaped in planar fashion and having at least one storage surface and at least one radiation-emitting component, and at least one holding apparatus for holding the storage element.

An organic luminous means and an illumination device comprising such a luminous means are specified. An optical display apparatus, emergency lighting, motor vehicle interior lighting, an item of furniture, a construction material, a glazing and a display comprising such a luminous means and, respectively, comprising an illumination device having such a luminous means are furthermore specified.

An illumination system has at least two light sources of which at least one light source includes an LED, and a driver device designed to operate at least the one LED with a DC signal; a sensor device for determining at least one feature of the light output; an actual value storage device connected to the sensor device for storing an actual value of the feature; a setpoint selection device for storing a setpoint of the feature; and a control device connected on the input side to the actual value storage device for of transmitting the actual value, and to the setpoint selection device for transmitting the setpoint, and which provides the driver device with a control signal that changes a characteristic of the DC signal used for driving the LED such that the actual value approaches the setpoint.

Illumination system having at least two light sources, and a method for operating such an illumination system
