Light-emitting component and method of operating a light-emitting component
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.
