Patent

CA 2193820

A dusk-to-dawn switch for lighting means (12; 52) has a light sensing element (22) that reacts to ambient light and a switching unit (38; 54) designed to react to an output signal from the light sensing element (22) and to activate or deactivate the lightmeans (12; 52). The switching unit has a reference threshold generator (48; 68). The lighting means (12; 52) are activated or deactivated depending on whether the output signal from the light sensing element (22) exceeds or falls below a threshold generated by the reference threshold generator (48, 68), and the threshold level depends on the luminosity sensed by the light sensing element (22).

Cet interrupteur crépusculaire conçu pour un luminaire (12; 52) comprend un élément photo-détecteur (22) qui réagit à la lumière ambiante et une unité de commutation (38; 54) qui réagit à un signal de sortie de l'élément photo-détecteur (22) en activant ou en désactivant le luminaire (12; 52) et qui comprend un générateur (48, 68) d'un seuil de référence. Le luminaire (12; 52) est activé ou désactivé selon que le signal de sortie de l'élément photo-détecteur (22) se trouve au-dessus ou au-dessous d'un seuil généré par le générateur de seuil de référence (48, 68), le niveau du seuil étant dépendant de la luminosité détectée par l'élément photo-détecteur (22).
