Title
(EN) SAFETY INTERLOCK SYSTEM FOR ILLUMINATION SYSTEMS
(FR) SYSTÈME DE VERROUILLAGE DE SÉCURITÉ POUR SYSTÈMES D'ÉCLAIRAGE
Abstract
(EN)
An illumination system (200) includes an illumination device (202); an optical element (206) positioned to receive light (208) from the illumination device (202); a layer (210) of a transparent material disposed on the optical element (206) and positioned to receive light (208) from the illumination device (202); and an interlock circuit (220) configured to measure a resistivity of the layer (210) of transparent material and to control operation of the illumination device (202) based on the measured resistivity
(FR)
Un système d'éclairage (200) comprend un dispositif d'éclairage (202) ; un élément optique (206) positionné pour recevoir de la lumière (208) en provenance du dispositif d'éclairage (202) ; une couche (210) d'un matériau transparent disposé sur l'élément optique (206) et positionné pour recevoir la lumière (208) du dispositif d'éclairage (202) ; et un circuit de verrouillage (220) conçu pour mesurer une résistivité de la couche (210) de matériau transparent et pour commander le fonctionnement du dispositif d'éclairage (202) sur la base de la résistivité mesurée.
