Abstract
Description
L'invention a pour objet un dispositif de contrôle du fonctionnement d'une source de lumière, ampoule à filament ou fluorescente notamment, ainsi qu'une application d'un tel dispositif au contrôle des organes lumineux de signalisation d'un véhicule. The subject of the invention is a device for controlling the operation of a light source, in particular a filament or fluorescent bulb, as well as an application of such a device for controlling the light signaling members of a vehicle.
De façon habituelle, le contrôle du fonctionnement des ampoules à filament met en oeuvre le principe d'un contrôle de leur alimentation électrique. In the usual way, the control of the operation of filament bulbs implements the principle of a control of their electrical supply.
Par exemple dans une automobile, les témoins de contrôle des clignotants et les ampoules à filament y relatives s'allument simultanément, en raison de leur montage en parallèle et donc de leur alimentation conjointe en électricité. For example in an automobile, the indicator lights and the related filament bulbs light up simultaneously, due to their parallel connection and therefore their joint supply of electricity.
Un inconvénient réside dans le fait qu'une ampoule à filament peut ne pas fonctionner, mais le circuit parallèle du témoin autoriser néanmoins la circulation d'électricité, ce qui a pour conséquence une alimentation en électricité du témoin correspondant, et donc la communication d'une information fausse. A drawback lies in the fact that a filament bulb may not work, but the parallel circuit of the indicator nevertheless authorizes the circulation of electricity, which results in a supply of electricity to the corresponding indicator, and therefore the communication of false information.
Le but de l'invention est de proposer un dispositif fiable de contrôle du fonctionnement d'une source de lumière, ampoule à filament ou fluorescente notamment, et notamment un dispositif pour le contrôle du fonctionnement des organes lumineux de signalisation d'un véhicule. The object of the invention is to propose a reliable device for controlling the operation of a light source, in particular a filament or fluorescent bulb, and in particular a device for monitoring the operation of the light signaling members of a vehicle.
La démarche inventive a consisté à contrôler le fonctionnement réel d'une source de lumière, ampoule à filament par exemple, c'est à dire son émission lumineuse, au moyen d'une fibre optique dont l'une des extrémités est disposée en regard de l'organe générateur de lumière de la source lumineuse, par exemple en regard du filament de l'ampoule, et dont l'autre extrémité émerge d'un
Sur la figure, un dispositif de
contrôle du fonctionnement des ampoules à filament, telles
que 2, d'organes d'éclairage, est principalement caractérisé
en ce qu'il est principalement constitué d'une fibre 4
conductrice de lumière, dite fibre optique, telle que fibre
de polyméthacrylate, de macrolon ou de verre, dont une extrémité 6, conformée de préférence en guide-onde ou cornet,
est destinée à être disposée à proximité du filament de
l'ampoule 2 à contrôler, et dont l'autre extrémité 8 est
destinée à émerger d'un tableau de contrôle 10, de telle
sorte que la lumière produite par l'ampoule 2 à contrôler,
qui constitue un exemple de source lumineuse, est véhiculée
depuis son emplacement jusqu'au tableau de contrôle 10.The inventive step consisted in controlling the real functioning of a light source, filament bulb for example, that is to say its light emission, by means of an optical fiber one end of which is arranged opposite the light-generating member of the light source, for example facing the filament of the bulb, and the other end of which emerges from a
In the figure, a device for
control of the operation of filament bulbs, such as
that 2, of lighting elements, is mainly characterized
in that it mainly consists of a fiber 4
light-conducting, called optical fiber, such as fiber
polymethacrylate, macrolon or glass, one end of which 6, preferably shaped as a waveguide or horn,
is intended to be placed near the filament of
the bulb 2 to be checked, and the other end of which 8 is
intended to emerge from a control panel 10, such
so that the light produced by the bulb 2 to be controlled,
which is an example of a light source, is conveyed
from its location to the control panel 10.
Il résulte de ces dispositions que
l'information transmise du fonctionnement de l'ampoule à
contrôler est fiable en raison de la prise de l'information
réelle directement à partir de la lumière émise par l'ampoule
2.It follows from these provisions that
the information transmitted from the operation of the bulb to
control is reliable due to taking information
real directly from the light emitted by the bulb
2.
Un exemple privilégié d'application
du dispositif de l'invention, est l'application au contrôle
du fonctionnement des ampoules de signalisation des
véhicules, telles que clignotant, feu stop, feu de recul,
veilleuse, etc...A privileged example of application
of the device of the invention, is the application to control
the operation of the signaling light bulbs
vehicles, such as turn signal, brake light, reversing light,
night light, etc ...
Le tableau de contrôle 10 est placé
dans la zone du tableau de bord du véhicule, et comporte une
pluralité de témoins matérialisés par des capots
translucides, tels que 12, de protection de l'extrémité
émergeante d'une fibre optique 4 en provenance respectivement
de chacune des ampoules à contrôler.Control panel 10 is placed
in the vehicle dashboard area, and has a
plurality of witnesses materialized by hoods
translucent, such as 12, end protection
emerging from an optical fiber 4 coming respectively
of each of the bulbs to be checked.
Bien que l'on ait décrit et
représenté une forme et une application préférées de
l'invention, il doit être compris que la portée de cette
dernière n'est pas limitée à cette forme et application, mais
qu'elle s'étend à tout dispositif comportant les
caractéristiques énoncées plus haut. Although we have described and
depicted a preferred form and application of
invention, it should be understood that the scope of this
the latter is not limited to this form and application, but
that it extends to any device comprising the
characteristics set out above.
