Method for operation-optimized control of a deflection unit (DU) for a light module. The light module is designed to emit segmented light distribution. The light module includes the DU, with which a native resolution of the light module can be visually increased by at least temporary beam deflection via the DU. The method includes: a) receiving a setpoint operating signal (SOS) which contains information on at least one of: setpoint's energy efficiency, temperature, image resolution, image sharpness, clarity, or offset correction; and b) manipulating a control variable (CV) of the DU depending on the SOS, wherein the extent and temporal process of deflection by the DU occurs depending on the CV. At least two of the following aspects of the deflection, predetermined by the CV, are manipulated in amount and/or time period: amplitude; zero position; temporal rate of change; signal basic form; or time period between the zero position passes.

Method for operation-optimized control of a deflection unit

Light module for a motor vehicle light including a light source, projection unit, deflection unit, and control unit. The light source is designed to receive a light control signal (LCS) and emit spatially modulated light (SML) as a function of the LCS. The projection unit is designed to project the SML emitted by the light source within a projection angular range (PAR) in front of the light module. The deflection unit is designed to receive a deflection control signal (DCS) and manipulate the SML emitted by the light source as a function of the DCS such that the projection of the SML emitted by the light source can be displaced in front of the light module with a displacement angle within the PAR. The control unit is designed to receive and evaluate an input signal and to transmit the LCS to the light source based on said evaluation.
