    Abstract: An arrangement includes a semiconductor chip with a first and second electrode. The arrangement also includes a control unit for adjusting a current for operating the semiconductor chip, a first LED voltage input coupled to the first electrode, and a reference voltage input coupled to the second electrode. The arrangement further includes an LED data input coupled to the control unit, by which a data parameter representative of a current for operating the semiconductor chip is provided. The arrangement additionally includes a cycle input coupled to the control unit, by which a reference cycle signal is provided which is representative of an operating phase of the arrangement. The control unit includes a memory arranged to record the data parameter as a memory value depending on the reference cycle signal. The control unit is configured to adjust the current depending on the memory value.

    Abstract: Light-emitting component includes a light source and a dimming element arranged downstream of the light source in a radiation direction. The dimming element includes a dimming layer. The light source includes at least one emitter which is configured to emit light. A brightness of a light emitted by the light-emitting component is adjustable. The brightness is partially adjustable by way of a pulse width modulated and/or amplitude modulated operating signal for the emitter, and the brightness is partially adjustable by way of partial absorption and/or reflection of the light emitted by the emitter in the dimming element. A dimming capability of the dimming layer increases along an extension direction transverse to the radiation direction. The dimming layer is displaceable along the extension direction relative to the light source. A degree of absorption and/or reflection of light emitted by the emitter is variably adjustable.
