Abstract
An automatic lamp control device in which a Doppler radar module, a switching unit for switching a lamp circuit on and off, a circuit configuration for evaluating Doppler radar module signals and for producing signals for controlling the switching unit, and a power supply unit for supplying current to the Doppler radar module and to the circuit configuration are provided on a printed circuit board configuration. The lamp control device reacts to movements within the transmitting and receiving range of the Doppler radar module. The range is independent of the ambient temperature. The lamp control device can be configured to save space, in such a way that it can be integrated completely in a standard flush-mounted box.
