Definitions
- the present invention relates to a light information device concerning the state of operation of a system and a management method such a device, particularly in the field of avionics.
- the pilots are therefore led to check regularly the good working order of such indicators via a test command which has the effect of lighting up a pre-determined set of these, for example those of the ceiling panel.
- the drivers must then change the faulty LEDs to line.
- a command button 12 causes the simultaneous lighting of all these lights and allows the pilot to easily spot a light that remains off.
- the subject of the invention is a device of light information of the operating state a system to overcome the disadvantages devices of the prior art by detecting the breakdowns of signaling indicators and in guaranteeing a good functioning even in the presence of some failures.
- the invention also relates to a method of managing such a device.
- the present invention relates to a light information device concerning the state of operation of a system comprising at least one indicator light and means for detecting failure of this or these LEDs, characterized in that each LED includes m branches in parallel each consisting of n electroluminescent diodes in series, and means of selection of a branch, m and n being numbers integers such that: m ⁇ 2 and n ⁇ 1.
- each indicator, its module control and its switch are integrated in a single housing.
- the present invention also relates to a method of managing an information device light concerning the operating status of a system, comprising several LEDs each comprising several branches of several luminous elements, in which has a permanent automatic test step of all the lights of the system.
- the process comprises a step of dynamic management of the redundancy in case of failure of a branch of a light.
- the duty cycle other flawless branches is changed to keep the same overall brightness at the LED.
- the invention can advantageously be used in the avionics field.
- FIGS 1 and 2 illustrate two devices of the prior art.
- FIGS 3 and 4 illustrate the device of the invention.
- FIG. 5 illustrates an embodiment advantageous of the device of the invention.
- a voltage measuring device 34 connected between the E input and the S output of the LED allows to know the voltage at the terminals of this indicator.
- An intensity measuring device 35 connected in output of the indicator 29 makes it possible to know the intensity of the current running through it.
- the light 29 is powered by a current generator 40.
- a control module 41 driver on the one hand the selector 33 via a line 43 and secondly a switch 42 via a line 44.
- This control module 41 contains a memory for storing the functional state or not of each branch 31.
- the control signal of this module 41 conveyed on a command line 45, is a classic order given to a seer (On / off).
- a line of record 46 allows report the state of this seer 29 to external devices for alarm or maintenance for example.
- the method of the invention also provides a dynamic management of the redundancy of each which consists, using the selector 33, in alternately select the different branches 31 of this indicator with a polling frequency sufficiently high (of the order of a few kHz) for not to be perceived by the human eye.
- the parameters current / voltage of the indicator are checked. If a defect is found, the court branch is no longer requested and the other branches have their report cyclical ignition modified to keep the same overall brightness at the LED.
- the method of the invention thus allows to avoid the total loss of the light. Also, even when the indicator light is not lit, the method of the invention continues his dynamic test by performing a brief control of the different branches. Upon the loss of first branch, it is possible to develop a message preventive maintenance without the pilot being informed.
- the control module 41 opens and closes the switch 42 so as to power the seeing 29 by pulses sufficiently brief, by example of a duration of the order of a few microseconds, and spaced out so that the LED 29 seems extinct to an observer.
- Each pulse is switched successively by the selector 33 on one of the branches 31. It measures the voltage across this branch and the current running through it.
- the control module 41 closes the switch 42 so as to power the indicator 29 permanently. Cyclically, the selector 33 controlled by the signal C feeds the branches 31 functional one after the other.
- branch (s) in question can (wind) be requalified as functional, the LED emitting less light than when it was nominal operation.
- Any failure detection can result in the emission of a signal on the line of report, intended for an operator and / or any maintenance.
- the indicator light 29, its module control 41 as well as the switch 42 are integrated in a single housing 50, with two lines 51, so as to present the appearance outside of an almost classic sight.

Abstract
Description
- une consommation importante pendant le test, surtout lorsque ces voyants sont des lampes à incandescence,
- une impossibilité de détecter un voyant tombé en panne postérieurement au test,
- une efficacité du test reposant sur la vigilance de l'opérateur.
- un ensemble émetteur de lumière composé de m branches de n diodes électroluminescentes connectées en série et dans le même sens, les m premières extrémités de chaque branche étant connectées ensemble, leurs secondes extrémités étant connectées aux différentes entrées d'un sélecteur,
- ce sélecteur qui, en fonction d'un ordre de commande, relie une branche sélectionnée vers la sortie.
- un générateur de courant qui alimente ce voyant,
- un module de commande qui pilote le sélecteur ainsi qu'un interrupteur,
- cet interrupteur qui est relié entre la sortie du sélecteur et l'entrée du générateur de courant.
- dans le cas où le voyant est allumé, on vérifie son bon fonctionnement en contrôlant l'intensité consommée et la tension présente à ses bornes,
- dans le cas où ce voyant est éteint, on le sollicite pendant une durée de l'ordre de quelques microsecondes et on mesure à cet instant ses paramètres courant/tension.
- un ensemble 30 émetteur de lumière composé de m branches 31 de n diodes électroluminescentes (DEL) 32 (avec m ≥ 2 et n ≥ 1) les n diodes de chaque branche étant connectées en série et dans le même sens, les m premières extrémités de ces branches 31 étant connectées ensemble à l'entrée E, leurs secondes extrémités étant connectées aux différentes entrées d'un sélecteur 33,
- ce sélecteur 33, qui en fonction d'un ordre de commande C, relie une des branches 31 sélectionnée à la sortie S.
- dans le cas où un voyant est allumé, il est facile de vérifier son bon état de fonctionnement en contrôlant régulièrement l'intensité consommée et la tension présente à ces bornes.
- dans le cas où un voyant est éteint, on utilise le même principe de mesure en sollicitant brièvement ce voyant. On alimente alors ce voyant durant une durée de l'ordre de quelques microsecondes, non perceptible par l'oeil humain, en respectant les valeurs de commande nominales. On mesure, à cet instant, les paramètres courant/tension de ce voyant.
- un courant nul : le circuit est ouvert et la branche ne peut plus fonctionner. Elle est considérée comme non fonctionnelle.
- une tension plus faible que la tension nominale : une diode au moins est en court-circuit. Le fait de considérer ou non la branche comme fonctionnelle dépend du rapport entre le nombre de diodes en bon état et le nombre de diodes de la branche, qui se trouve égal au rapport entre la tension mesurée et la tension nominale. Le fabricant ou l'utilisateur décide à partir de quelle baisse d'efficacité une branche doit être déclarée non fonctionnelle. Un tel mode de fonctionnement "voyant éteint" permet au module de commande 41 de connaítre avant tout ordre d'allumage, les branches fonctionnelles qui pourront être utilisées en mode "voyant allumé".
- un courant nul : le circuit est ouvert et la branche ne peut plus fonctionner. Elle est considérée comme non fonctionnelle.
- une tension plus faible que la tension nominale : une diode au moins est en court-circuit. Le fait de considérer ou non la branche comme fonctionnelle dépend du rapport entre le nombre de diodes en bon état et le nombre de diodes de la branche qui se trouve égal au rapport entre la tension mesurée et la tension nominale.
