    Abstract: The movement detector (1) has a push-button operating switch (2), coupled to an electronic control and evaluation stage (3), for manual switching of the operating mode between an automatic mode, a timed switched on mode for the lighting device (6), or a timed switched off mode for the lighting device, using short-term and/or long-term depression of the push-button switch.

    Abstract: The invention relates to a device for receiving light beams, especially a PIR movement detector, having a housing which has at least one window in which first lens segments (LS1), preferably configured as Fresnel lenses, are arranged in such a way that horizontally incident light beams are focused as direct horizontal beams (S1, S2) onto two light sensors (W1, W2) and the two light sensors (W1, W2) are mutually arranged in such a way that the usable sensor detection angle (a1+a2) of both light sensors (W1, W2) is valid. In order to achieve an enlargement of the detection angle, it is proposed that, in the region of at least one light sensor (W1, W2), at least one horizontal reflector (R1, R2) is arranged so that the latter detects further light beams from a horizontal angular region not covered by the light sensors (W1, W2) with their usable detection angle (a1+a2), and these beams reach at least one light sensor (W1, W2) as reflected horizontal beams (S3, S4). It is furthermore provided that the first lens segments (LS1) surround the light sensors (W1, W2) having the at least one horizontal reflector (R1, R2) in a curve-shape to such an extent that they also focus horizontal beams (S3, S4) which are incident outside the usable sensor detection angle (a1+a2).
