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
