Abstract

Apparatus for checking automobile lamps. The invention makes it possible to signal, by the flashing of a test lamp, a defect in the various lamps for lighting, signalling, braking, etc., by virtue of an electronic circuit. It comprises a current detector 1, a monostable oscillator 2, a comparator 3, a power interface between the circuit and the test lamp 4. Advantages of the circuit: - makes it possible to check the correct operation of the lamps at any moment without getting out of the vehicle.

Description

La présente invention signale, par une lampe témoin qui se trouve sur le tableau de bord du véhicule, un défaut sur.les différentes lampes d'éclairage, de signalisation, de freinage, etc... The present invention signals, by a warning lamp which is located on the dashboard of the vehicle, a fault on the various lighting, signaling, braking, etc. lamps.

Ce dispositif est très utile du fait que l'on ne peut pas vérifier ses lampes quand le véhicule roule. This device is very useful because you cannot check its lamps when the vehicle is moving.

Avec ce circuit, il existe deux manières pour différencier une panne: - la lampe témoin du tableau de bord est en allumage
constant: c'est qu'il y a un manque de pression ou de
liquide de frein; - la lampe témoin du tableau de bord clignote: ctest
qu'unie lampe est grillée.With this circuit, there are two ways to differentiate a fault: - the indicator light on the dashboard is on
constant: there is a lack of pressure or
brake fluid; - the instrument panel warning light flashes: ctest
that a lamp is burnt out.

Le dessin ci-joint est un schéma de principe de montage 1/1. The attached drawing is a 1/1 mounting block diagram.

Le circuit est composé de quatre parties distinctes: 1 - le détecteur de courant, 2 - l'oscillateur monostable, 3 - un comparateur, 4 - un interface de puissance entre le circuit et la
lampe témoin.The circuit is made up of four distinct parts: 1 - the current detector, 2 - the monostable oscillator, 3 - a comparator, 4 - a power interface between the circuit and the
pilot light.

Le circuit de détection de courant est monté en série avec les lampes L2. I1 est composé d'une bobine d'intensité bl qui est enroulée autour d'une ampoule à lame souple aimantée ILS1. Si l'intensité est à sa valeur normale, l'ampoule souple ILS1 fait un contact électrique grâce au nombre d'ampère-tours créé par la bobine bl. The current detection circuit is connected in series with the L2 lamps. I1 is composed of a coil of intensity bl which is wound around a bulb with a flexible magnetic blade ILS1. If the intensity is at its normal value, the flexible bulb ILS1 makes an electrical contact thanks to the number of ampere-turns created by the coil bl.

Dans le cas contraire, le contact dans l'ampoule ILS1 ne se fait pas.Otherwise, contact in the ILS1 bulb is not made.

Pour faire clignoter la lampe témoin L1, on fait appel à un oscillateur monos table fabriqué avec trois portes NI du circuit intégré Al. La variation du temps d'allumage ou d'extinction de la lampe témoin Li se fait grace au condensateur C1 et à la résistance R2. To make the indicator lamp L1 blink, we use a single-table oscillator made with three NI doors of the integrated circuit Al. The variation of the on or off time of the indicator lamp Li is made thanks to the capacitor C1 and to resistance R2.

Le comparateur est composé par la dernière porte NI du circuit intégré Al; une de ses entrées est reliee à l'oscillateur monostable et l'autre à la masse via la résistance R1. The comparator is composed by the last gate NI of the integrated circuit Al; one of its inputs is connected to the monostable oscillator and the other to ground via the resistor R1.

Lorsque les lampes L2 sont bonnes, les entrées du comparateur sont mises au positif à l'aide de l'ampoule
ILS1, donc pas d'impulsion à sa sortie. Par contre, si les deux entrées sont mises au negatif, c'est qu'il y a une lampe de grillée: à la sortie du comparateur, il y a une impulsion et c'est à ce moment là que rentre en service l'interface de puissance. I1 est composé de la résistance R3 qui met en fonctionnement le transistor Tl qui allume ou éteint la lampe témoin L1 via la diode Dl. When the L2 lamps are good, the comparator inputs are set to positive using the bulb
ILS1, therefore no pulse at its output. On the other hand, if the two inputs are set to negative, it means that there is a burnt out lamp: at the output of the comparator, there is a pulse and it is at this point that the power interface. I1 is composed of the resistor R3 which activates the transistor Tl which turns on or off the indicator lamp L1 via the diode Dl.
