  • Patent number: 9964270
    Abstract: An optoelectronic semiconductor component and an adaptive headlight are disclosed. In an embodiment an optoelectronic semiconductor component includes a carrier having a carrier top side and a carrier underside, a plurality of active zones, which are fitted at the carrier top side and which are designed for emitting radiation, electrical contact locations at the carrier underside, which are designed for electrically connecting the semiconductor component and a drive unit for electrically addressing the semiconductor component and for electrically driving the active zones, wherein the active zones are fitted in a regular grid at the carrier top side, wherein the grid has a grid pitch, wherein geometrical midpoints of radiation main sides of the active zones lie on grid points of the grid, and wherein a distance between the geometrical midpoints of marginal active zones and a closest edge of the carrier is at most 50% of the grid pitch.

  • Patent number: 9591705
    Abstract: A method is set up to operate an arrangement that has N radiation-emitting semiconductor chips arranged in an electric series circuit. The arrangement includes multiple switching elements, wherein to each of the semiconductor chips one of the switching elements is connected electrically in parallel. The arrangement includes a controller for the mutually independent activation of the switching elements. The arrangement includes a constant current circuit for energizing the series circuit. When switching off, the respective semiconductor chip associated with a switching element is bridged electrically by the switching element. A protective module of the arrangement is set up to reduce or to prevent current peaks when one or more of the semiconductor chips is/are switched off.
