Abstract: A lighting device (1) and an operating method for the lighting device (1), which comprises at least one base chip (21) and a plurality of cover emitter regions (22). The base chip or chips (21) and the cover emitter regions (22) are realized by light-emitting diode chips and are electrically controlled independently of one another. Main emission directions (M) of these light-emitting diode chips are oriented parallel to one another. The cover emitter regions (22) are partially overlapping with the at least one base chip (21), so that an overlap region (3, B) is formed and the at least one base chip (21) radiates through the cover emitter regions (22) during operation. The cover emitter regions (22) are arranged in a common plane perpendicular to the main emission directions (M).

Abstract: An optical element has a first surface and a second surface opposite the first surface. The first surface is subdivided into at least one first segment and a second segment. The segments in each case adjoin a midpoint of the first surface. Each segment has a tooth structure having teeth extending along tooth extension directions. The tooth extension directions have bends at boundaries between the segments.

Abstract: The present invention relates to an LED backlighting system comprising a substrate, an optoelectronic semiconductor chip assembly, a reflector and a diffuser element. The optoelectronic semiconductor chip assembly is disposed on an upper side of the substrate. The reflector has a through-hole that extends between a lower opening on an underside of the reflector and an upper opening on an upper side of the reflector. The reflector is disposed on the upper side of the substrate so that the underside of the reflector is facing the upper side of the substrate. The optoelectronic semiconductor chip assembly is disposed in the through-hole of the reflector. The diffuser element has an upper side and an underside. The diffuser element is disposed above the upper side of the reflector so that the underside of the diffuser element is facing the upper side of the reflector.
