Abstract

Improvements introduced in the object of the main patent no. 466,009, deposited on december 23, 1977, by: "improvements in detection devices of the defective state of a lamp among several fed by direct current", comprising in accordance with the main patent a means to create an impedance when it is powered under an alternative voltage, an alternative voltage source connected between each of the lamps to be controlled and said means that is associated to it, as well as a device for detecting the variations of the voltage in the terminals of said own means, characterized in that the detector device comprises a differential device for detecting variations in the voltage at the terminals of the means of creating an impedance, capable of controlling two lamps mounted in parallel and constituted by two transistors, that the base of one of them and the emitter of the other are connected to the point of uni between one of the lamps and the medium to create an associated impedance, and inversely for the junction point of the second lamp.
