Electrical or electronic installation unit for building system, has movement sensitive lighting-microprocessor, where time calibration and twilight adjustment are controlled on infinite large falling delay and infinite small light value

摘要

The unit (1) has movement sensitive lighting-microprocessor (2) and a switching device. The time calibration (6) is controlled on an infinite large falling delay. The duration of the falling delay corresponds to an infinite large time period. The twilight adjustment (7) is controlled on an infinitely small light value. The light value with which the unit should begin with the compilation of the infrared radiation corresponds to absolute darkness which is never attained in a natural environment. Once switched off lighting device remains in the switched off condition.
