Abstract
An illumination device and process illuminate a surface of an object. The device includes plural illumination units and a signal processing control unit. Each illumination unit illuminates the surface with a maximum irradiance, wherein the device illuminates the surface with a maximum total irradiance that depends on the maximum irradiances of the illumination units. The device captures a maximum total irradiance user specification of the device or units. The control unit controls the maximum irradiance of each illumination unit independently and responds to the user specification by predicting the maximum total irradiance of the device operated according to the user specification, compares the predicted maximum total irradiance with a specified upper threshold and if greater than the upper threshold, controls one or more illumination units depending on the user specification such that the actually achieved maximum total irradiance is less than or equal to the upper threshold.
