Title
(EN) LED LIGHTING SYSTEM
(FR) SYSTÈME D’ÉCLAIRAGE À DEL
Abstract
(EN)
An LED lamp arrangement (1) adapted for fitting in a luminaire. The luminaire is adapted for a fluorescent lamp and having a ballast. The LED lamp arrangement has a plurality of LEDs (25, 26, 27) and two or more electrodes (22) for releasably connecting to the luminaire and for conducting current from the ballast for supply to the LEDs. The LED lamp arrangement further has a sensor circuit (21) and a protection circuit (24). The sensor circuit and the protection circuit are adapted to increase the total load impedance of the LED lamp arrangement if the ballast is a constant power electronic ballast.

L'invention concerne un agencement de lampe à DEL (1) conçu pour s'adapter dans un luminaire. Le luminaire est conçu pour une lampe fluorescente et ayant un ballast. L'agencement de lampe à DEL présente une pluralité de DEL (25, 26, 27) et deux électrodes (22) ou plus pour se connecter de manière libérable au luminaire et pour conduire le courant depuis le ballast pour alimenter les DEL. L'agencement de lampe à DEL présente en outre un circuit de capteur (21) et un circuit de protection (24). Le circuit de capteur et le circuit de protection sont conçus pour augmenter l'impédance de charge totale de l'agencement de lampe à DEL si le ballast est un ballast électronique à puissance constante.
