Title
(EN) A LAMP HAVING A SAFETY CIRCUIT, AND A SAFETY CIRCUIT FOR USE IN SUCH LAMPS
(FR) LAMPE COMPRENANT UN CIRCUIT DE SÉCURITÉ ET CIRCUIT DE SÉCURITÉ DESTINÉ À ÊTRE UTILISÉ DANS DE TELLES LAMPES
Abstract
(EN)
A lamp has a safety circuit connected to first and second electrical connection terminals. A test is used to detect if the first and second electrical connection terminals are both connected to external power without an interfering impedance such a human body, and only then enable operation of the lamp. A time for the test is different from a time when another lamp in the system applies a test.
(FR)
L'invention concerne une lampe comprenant un circuit de sécurité connecté à des première et deuxième bornes de connexion électrique. Un test est utilisé pour détecter si les première et deuxième bornes de connexion électrique sont toutes deux connectées à une alimentation externe sans impédance d'interférence telle qu'un corps humain, et alors seulement autoriser le fonctionnement de la lampe. Un moment auquel est effectué le test est différent d'un moment auquel une autre lampe dans le système applique un test.
