Patent number: 11929455Abstract: An optoelectronic component may include a layer sequence having an active layer configured to emit an electromagnetic primary radiation and a conversion element arranged in the beam path of the primary radiation. The conversion element may include a conversion layer and a conversion potting arranged over the conversion layer. The conversion layer may include a first matrix material and a converter material, and the conversion potting may include a second matrix material and a converter material. There may be a jump in concentration of converter material between the conversion layer and the conversion potting.Type: GrantFiled: July 31, 2018Date of Patent: March 12, 2024Assignee: OSRAM OLED GmbHInventor: Norbert Harendt

Patent number: 11476384Abstract: A light source is specified which comprises a planar semiconductor light source comprising a plurality of independently operable single emitters, wherein, during operation, each of the single emitters emits light via respective single luminous surface. Furthermore, the light source has a common optical element which is arranged directly downstream of the single emitters and which is embodied and intended to direct light from different single emitters into different solid angle regions, wherein the single emitters are arranged defocused with respect to the optical element and the individual light surfaces are imaged in a blurred manner by the optical element.Type: GrantFiled: December 11, 2018Date of Patent: October 18, 2022Assignee: OSRAM OLED GMBHInventors: Ralph Peter Bertram, Norbert Harendt
