Bewegungsmelder

摘要

A motion detector is proposed for switching at least one light source as a function of movement, having a switching stage (2), which connects, as required, the at least one light source (1) to an energy-supply stage (3) and which can be controlled as a function of the signals of a motion sensor (5) as soon as the instantaneous light intensity falls below a lower brightness limit which can be predetermined. The instantaneous light intensity is simulated by a time module (17, 17') in accordance with the position of the sun, as defined by sunrise and sunset, as a function of the instantaneous calendar day and the instantaneous calendar month. Either a calendar unit (10) and a clock unit (9) or a radio-controlled clock receiver (18) serve to predetermine the instantaneous calendar day, the instantaneous calendar month and the instantaneous time.
