摘要： The invention relates to an electroluminescent lighting device, which is based on an array of standard electroluminescent tiles (D1-Dn) combined with an array of ballast components (R1-Rn) mounted on a carrier board (30) in such a way that the power loss is evenly spread across the whole board area to minimize local electric power in the ballast components. The unavoidable remaining hot spots and electroluminescent tiles are thermally coupled in such a way that the additional thermal load on the electroluminescent emission layer is as symmetric as possible with respect to the self heating of the electroluminescent device. This can be achieved by a combination of properly designed heat spreading and thermal isolation of the electroluminescent and ballast components. Heat spreading is achieved by a properly designed interconnection structure (40) on the carrier board. Different options are proposed to thermally isolate the electroluminescent tiles from the hot spots.

摘要： The invention relates to supervision circuits (10) for supervising organic light emitting diode devices (1) via detection circuits (20) for detecting failure states of the organic light emitting diode devices (1) and for generating decision signals in response to detected failure states of the organic light emitting diode devices (1), which detected failure states have durations equal to or larger than time intervals. In response to the decision signals, the organic light emitting diode devices (1) can be bypassed and deactivated through switching circuits (30) such as bi-stable circuits. The failure states may include that the organic light emitting diode devices (1) have a relatively low impedance or “short” and a relatively high impedance or “open”. The supervision circuit (10) further prevents the organic light emitting diode devices (1) from being bypassed unjustly. The supervision circuits (10) may be autonomous circuits that only receive power via the organic light emitting diode devices (1) and may be automatic circuits that automatically reset themselves after turn-off.

摘要： The invention relates to a light apparatus (1) for generating light. The light apparatus includes a light emission structure (2) including light emission material (9), a capacitor structure (3) including at least two capacitor electrode films (11, 12) and a dielectric film (14) between the capacitor electrode films, and a film encapsulation (30) including at least one film for encapsulating and thereby protecting at least the light emission material. The capacitor structure is integrated in the light apparatus such that the capacitor electrode films and the dielectric film are at least partly arranged in parallel to the light emission structure. Since films, in particular, thin films, are used for the capacitor structure and the encapsulation and since the capacitor structure is integrated in the light apparatus, the light apparatus can be relatively thin.
