Abstract
Bei Bewegungsmeldern mit einer segmentierten Sammeloptik entstehen zwischen den einzelnen fokussierenden Segmenten Toträume, in denen sich ein Strahlungsobjekt aufhalten kann, ohne ein Signal auszulösen. Bei dem neuen Bewegungsmelder sollen diese Toträume praktisch vermieden werden. For motion detectors with a segmented Collection optics arise between the individual focusing segments dead spaces in which a radiation object can stop without one Trigger signal. With the new motion detector these dead spaces should be practically avoided.
Hierzu wird hinter der Sammeloptik (1) eine Ablenk optik (3) angeordnet, die jeweils einen Teil des parallel zum Hauptstrahl (6) eines Segmentes (2) einfallenden Strahlenbündels (8) so ablenkt, daß mindestens zwei Strahlungsmaxima entstehen. Diese Strahlungsmaxima treffen bei entsprechender Posi tionsänderung des Strahlungsobjektes (13) nachei nander auf Sensorelemente (7) des Sensors (5) auf. Die Toträume werden dadurch soweit verkleinert, daß sie praktisch entfallen. For this purpose, a deflection is behind the collecting optics (1) optics (3) arranged, each part of the parallel to the main beam (6) of a segment (2) deflecting incident beam (8) so that at least two radiation maxima arise. These Radiation maxima meet with the corresponding posi tion change of the radiation object (13) nachei on sensor elements (7) of the sensor (5). The dead spaces are reduced so much that they practically disappear.
Der Bewegungsmelder dient zur Raumüberwachung innerhalb und außerhalb von Gebäuden. Durch Signal gabe kann er eine Beleuchtung einschalten oder einen Alarm auslösen. The motion detector is used for room monitoring inside and outside of buildings. By signal he can turn on lighting or to trigger an alarm.
