DÄMMERUNGSSCHALTER MIT C-MOS-SPEICHER ZUR UNTERDRÜCKUNG OPTISCHER RUCKKOPPLUNGEN TWILIGHT SWITCH WITH C-MOS MEMORY FOR SUPPRESSION OF OPTICAL FEEDBACK

Ein Dämmerungsschalter, der durch die optische Rückkopplung der geschalteten Leuchte nicht beeinflußt wird.A twilight switch that is switched by the optical feedback of the Luminaire is not affected.

Energie kann bei Außen-, Treppen- und Flurbeleuchtungen nur gespart werden, wenn jede Leuchte durch einen Dämmerungsschalter gesteuert wird. Mit auf dem Markt erhältlichen Dämmerungsschaltern ist dies wegen der optischen Rückkopplung nicht möglich, da der Dämmerungsschalter nicht in die Leuchte integriert werden kann.Energy can only be saved with exterior, stair and corridor lighting when each lamp is controlled by a twilight switch. With twilight switches available on the market, this is not possible due to the optical feedback, as the twilight switch cannot be integrated into the luminaire.

Die Lösung des Problems sind zwei antiparallel arbeitende Fotoelemente. Das Fotoelement 1 schaltet bei abnehmendem Umgebungslicht über den Speicher 4 und die Thyristorsteuerung 5 die Leuchte ein. Das durch die optische Rückkopplung auf das Fotoelement 2 einwirkende Licht reicht nicht aus, um den Speicher zurück zusetzen. Die Ausschaltschwelle wird erst erreicht, wenn das Umgebungslicht wieder zunimmt.The solution to the problem are two photo elements working antiparallel. When the ambient light decreases, the photo element 1 switches the light via the memory 4 and the thyristor control 5 a. The light acting on the photo element 2 through the optical feedback is not sufficient to reset the memory. The switch-off threshold is only reached when the ambient light increases again.
