A lighting module for the controlled emission of light by means of lighting elements (1; 1a,..., 1d), comprising - at least two lighting elements (1; 1a,..., 1d), - wherein the individual lighting elements (1; 1a,..., 1d) are each arranged rotatably, in particular about a common axis, and are each arranged pivotably, in particular with respect to the common axis, - a control unit in communication connection with the individual lighting elements (1; 1a,..., 1d), and - at least one sensor for measuring at least one, in particular physical and/or chemical, parameter in the environment of the lighting module, - wherein the sensor is in communication connection with the control unit, - wherein the sensor is designed to determine, in particular repeatedly at predetermined times, measured values of the at least one parameter, and - wherein the control unit is designed to activate selected lighting elements (1; 1a,..., 1d) individually, in particular to switch them on, and/or to adjust their rotational and/or pivoting position when a measured value corresponding to at least one predetermined criterion is determined by the at least one sensor characterized in that - the lighting module is modularly constructed from a plurality of individual segments (8; 8a,..., 8e), wherein each lighting element (1; 1a,..., 1d) is accommodated in each case in a separate segment (8; 8a,..., 8e), and wherein the lighting module is expandable by further segments (8; 8a,..., 8e), in particular by further segments (8; 8a,..., 8e) with lighting elements (1; 1a,..., 1d) and that - the lighting module has a substantially cylindrical shape, and that the segments (8; 8a,..., 8e) of the lighting module form subsections of the lighting module with a substantially cylindrical shape. - at least two lighting elements (1; 1a,..., 1d), - wherein the individual lighting elements (1; 1a,..., 1d) are each arranged rotatably, in particular about a common axis, and are each arranged pivotably, in particular with respect to the common axis, - wherein the individual lighting elements (1; 1a,..., 1d) are each arranged rotatably, in particular about a common axis, and are each arranged pivotably, in particular with respect to the common axis, - a control unit in communication connection with the individual lighting elements (1; 1a,..., 1d), and - at least one sensor for measuring at least one, in particular physical and/or chemical, parameter in the environment of the lighting module, - wherein the sensor is in communication connection with the control unit, - wherein the sensor is designed to determine, in particular repeatedly at predetermined times, measured values of the at least one parameter, and - wherein the control unit is designed to activate selected lighting elements (1; 1a,..., 1d) individually, in particular to switch them on, and/or to adjust their rotational and/or pivoting position when a measured value corresponding to at least one predetermined criterion is determined by the at least one sensor - wherein the sensor is in communication connection with the control unit, - wherein the sensor is designed to determine, in particular repeatedly at predetermined times, measured values of the at least one parameter, and - wherein the control unit is designed to activate selected lighting elements (1; 1a,..., 1d) individually, in particular to switch them on, and/or to adjust their rotational and/or pivoting position when a measured value corresponding to at least one predetermined criterion is determined by the at least one sensor - the lighting module is modularly constructed from a plurality of individual segments (8; 8a,..., 8e), wherein each lighting element (1; 1a,..., 1d) is accommodated in each case in a separate segment (8; 8a,..., 8e), and wherein the lighting module is expandable by further segments (8; 8a,..., 8e), in particular by further segments (8; 8a,..., 8e) with lighting elements (1; 1a,..., 1d) and that - the lighting module has a substantially cylindrical shape, and that the segments (8; 8a,..., 8e) of the lighting module form subsections of the lighting module with a substantially cylindrical shape.
