Abstract: An indicator apparatus, having a pulse width modulation circuit (1), a demultiplexer (2) which has at least one signal input (21) and at least two signal outputs (22), wherein the signal input (21) is connected to the pulse width modulation circuit (1), and at least two light-emitting diodes (3) which are each connected to a signal output (22) of the demultiplexer.
Abstract: A lamp (100), having a plurality of light-emitting diodes (1), a focusing optical element (10, 11) being arranged downstream of each light-emitting diode (1), an electrically adjustable diffuser (3), which is arranged downstream of the focusing optical element (10, 11) in a main beam direction of the light-emitting diodes (1), and a control device (4), which is connected to the diffuser (3) and by means of which the light-scattering properties of the diffuser (3) may be adjusted.
