Lighting device with consistent lighting properties

A lighting device for coordinated lighting, comprising:

• a plurality of spatially distributed lighting units, wherein each lighting unit has a light source, a first sensor, and a calibrating device, the calibration device having a storage unit, each of the lighting units being individually calibrated so that the calibrating device of the particular lighting unit has individual calibration values stored in the storage unit, wherein the individual calibration values represent value pairs of calibrated actual values and corresponding measurement values of the first sensor;
• and
• a regulating device that receives the corresponding measurement values from the first sensor of each of the lighting units, forwards the corresponding measurement values to the calibrating device of each of the lighting units, and forwards specified color and/or intensity values to the calibrating device of each of the lighting units,
• wherein the calibrating device of each of the lighting units, based on the corresponding measurement values and the specified color and/or intensity values, forms a control value, by which the light source of the respective lighting unit is actuated in order to achieve the specified color and/or intensity value.

A lighting device for the coordinated lighting, comprising:

• a regulating device;
• a first lighting unit including a first semiconductor light-emitting element and a first sensor, the first semiconductor light-emitting element having a first light characteristic, the first lighting unit being individually calibrated with first calibration values;
• a second lighting unit including a second semiconductor light-emitting element and a second sensor, the second lighting unit being individually calibrated with second calibration values, the second semiconductor light-emitting element having a second light characteristic that is different from the first light characteristic of the first semiconductor light-emitting element, the second lighting unit being spatially separated from the first lighting unit;
• and
• a calibrating device including a storage unit having the first and second calibration values stored therein,
• wherein, in an operating state, the first sensor measures radiation emitted by the first semiconductor light-emitting element, the second sensor measures radiation emitted by the second semiconductor light-emitting element, and the radiation measured by the first and second sensors is forwarded to the calibrating device,
• wherein the calibrating device, in the operating state, forms a corrected color and/or intensity values based on the radiation measured by the first and second sensors, and
• wherein the regulating device, in the operating state, forms a control value based on the corrected color and/or intensity values and actuates the first and second semiconductor light-emitting elements with the control value to achieve a specified color and/or intensity value.
