Patent number: 9485831Abstract: 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.Type: GrantFiled: February 17, 2015Date of Patent: November 1, 2016Assignee: OLEDWORKS GMBHInventor: Dirk Hente

Patent number: 9312314Abstract: 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.Type: GrantFiled: January 18, 2013Date of Patent: April 12, 2016Assignee: Koninklijke Philips N.V.Inventors: Dirk Hente, Holger Spahr, Sami Hamwi, Alexander Rohr, Wolfgang Kowalsky, Torsten Rabe

Patent number: 9295131Abstract: 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.Type: GrantFiled: March 1, 2013Date of Patent: March 22, 2016Assignee: OLEDWORKS GMBHInventor: Dirk Hente

Patent number: 9173268Abstract: The invention relates to a current determination apparatus for determining an operational driving current for driving a light source of a group of light sources. A same color shift function defining a light color shift depending on a driving current can be provided for all light sources of the group. An operational driving current is determined based on the color shift function such that the light color (43) of the light source of the group of light sources is shifted from a nominal color, which may be specific for each light source, to a light color (45) within a target color window (41). Since for the different light sources the same color shift function can be used, a determination of individual operational driving currents such that the light sources of the group emit light having substantially the same color can be simplified.Type: GrantFiled: July 12, 2012Date of Patent: October 27, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Dirk Hente, Joseph Hendrik Anna Maria Jacobs, Céline Catherine Sarah Nicole, Christian Kalkschmidt
