Description
Le systeme qui fait l'objet de ce brevet sert à résoudre principalement le problème rencontré tous les jours dans les escaliers de bâtiments ou autres, où l'éclairage est commandé par une minuterie et, qui s'éteind d'une façon brusque sans prévenir la personne qui serait en train de monter qui, souvent, se retrouve au milieu des escaliers dans le noir exposée au risque de trébucher, avec tout ce qui s'en suit... The system which is the subject of this patent serves mainly to solve the problem encountered every day on the stairs of buildings or other, where the lighting is controlled by a timer and, which turns off suddenly without warning the person who is going up, who often finds himself in the middle of the stairs in the dark exposed to the risk of tripping, with everything that follows ...
La solution oonsiste à, lorsque la minuterie arrive à sa fin, de relanoer une deuxième minuterie qui prend la relève en commandant la lumière mais oette fois, en diminuant l'intensité d'éclairage, suffisament pour prévenir la personne qui serait en train de monter tout en lui permettant de distinguer devant elle et pouvoir appuyer sur le bouton de réarmement de la minuterie principale. S'il nty a personne dans les escaliers et qu'aucun ordre n'est donné au bout d'un oertain temps après la fin de la première minuterie, l'éclaira- ge s'éteint totalement. The solution is to, when the timer comes to an end, to relano a second timer which takes over by controlling the light but this time, by decreasing the lighting intensity, enough to warn the person who is going up while allowing it to distinguish in front of it and be able to press the reset button on the main timer. If there is nobody on the stairs and no order is given after a certain time after the end of the first timer, the lighting goes out completely.
A oe système est associé, à l'allumage de l'éclairage, une mise en marche prcgréssive des ampoules. El effet il est connu qu'à froid les lampes à incandescence, ont une très faible résistance (10 à 20fois plus faible qu'à ohaud). Et donc à la mise sous tension elles sont paroouru par un courant très froid, qui fait monter le filament à une très grande température, qui le fait évaporer à chaque allumage
Jusqu'à ce qu'en chauffant les résistances atteignent leur résistance normale, et, donc, la température normale L'allumage progressif consiste à envoyer la tension de secteur par petit paliers Jusqu'à sa valeur maximale, ceci évite d'atteindre des températures excessives et donc, de prolonger la durée de vie de l'ampoule d'une façon notable, en limitant son évaporation à chaque mise en marche. With this system, when the lighting is switched on, the bulbs are switched on in advance. El effect it is known that when cold incandescent lamps, have a very low resistance (10 to 20 times lower than with hot). And therefore at power up they are appeared by a very cold current, which causes the filament to rise to a very high temperature, which makes it evaporate with each ignition
Until by heating the resistors reach their normal resistance, and, therefore, the normal temperature Progressive ignition consists in sending the mains voltage in small steps Up to its maximum value, this avoids reaching temperatures excessive and therefore, extend the life of the bulb significantly, limiting its evaporation each time it is started.
Le circuit realisant toute ces fonotions est organisé de la sorte : (1) Filtre empeohant les parasites, dus à l'appel brusque de courant par le triac lorsqu'il travaille en angle conduction, de se propager dans le secteur, ceci est imposé par la Norme Française. (2) Transformation de la tension du secteur, redressement et filtrage pour la tension dtalimenta- tison;; de plus cette partie isole le système par rapport au seoteur pour la seourité des usagers. (3) Détecteur du 0 volt de tension du seoteur pour la synchronisation de la partie "4" du circuit. (4) Générateur de rampes synchronisées sur l'onde du secteur et de période deux fois plus petite que celle du secteur, pour la oommande du trias en angle de con duotion. (5) Interface permettant la mise en conduction du triac tout en assurant l'isolation du circuit par rapport au secteur, pour la sécurité des usagers. (6) Triao dont les dimensions sont fonction de la puissance à oommander. (7) Interface realisant la mise en forme du signal de lancement de la minuterie, ainsi que la protection du système contre les signaux d'importance anormale qui pourrait venir des bouttons poussoir mis à la disposition des usagers. (8) Première minuterie, générant le temps pendant lequel l'éclairage sera allumé normalement (ce temps pourrait avoir une valeur autour de 2 minutes par exemple). (9) Deuxième minuterie, gFné- rant le temps pendant lequel l'éclairage sera deZfaibleintensité, pour prévenir l'usager et lui permettre de distinguer autour de lui (temps qui sera autour de 20 secondes par exemple). The circuit realizing all these concepts is organized in this way: (1) Filter preventing the parasites, due to the sudden current demand by the triac when it works in conduction angle, to propagate in the sector, this is imposed by French Standard. (2) Transformation of the mains voltage, rectification and filtering for the supply voltage; moreover, this part isolates the system from the sponsor for the sake of the users. (3) Detector of the 0 volt voltage in the booster for synchronization of part "4" of the circuit. (4) Generator of ramps synchronized on the wave of the sector and with a period half as small as that of the sector, for the control of the trias in angle of conduction. (5) Interface allowing the triac to go into conduction while ensuring the isolation of the circuit with respect to the sector, for the safety of users. (6) Triao, the dimensions of which depend on the power to be ordered. (7) Interface realizing the formatting of the timer start signal, as well as the protection of the system against signals of abnormal importance which could come from the push buttons made available to users. (8) First timer, generating the time during which the lighting will be switched on normally (this time could have a value around 2 minutes for example). (9) Second timer, generating the time during which the lighting will be of low intensity, to warn the user and allow him to distinguish around him (time which will be around 20 seconds for example).
Fonctionnement t lorsque les deux minuteries sont au reposs la tension d'alimentation est imposée, via la diode D3, à la borne e- numéroté 6 de l'ampli-op.Â2, de oe fait le triao ne peut être mis en oonduotion,
Lorsqu'un ordre de lancement de la première minuterie est donné, la tension précédente n'est plus imposée en e- de A2, le potentiel de oette borne diminu alors progressivement au fur et à mesure que le condensateur C3 se charge, ceci entraîne la mise en conduction du triac, aveo la charge de o3 jusqu'à atteindre 1800; cette phase de fonctionnement du système est celle qui réalise l'allumage progressif. L'éclairage ensuite se stabilise à sa valeur maximale et reste ainsi pendant toute la durée fixé par les composants C7 et P1.A la fin de cette durée, la première minuterie lanoe une deuxième minuterie qui, elle, impose pendant sa durée, un potentiel donné à la borne e- de A23 ce potentiel est fixable par les résistances R6,R7 et R13, pour agir sur l'angle de conduction du triao de tel sorte que l'éclairage ait une intensité suffisante pour permettre de distinguer devant soi tout en diminuant cet eclairage suffisament pour pouvoir sten apercevoir. Si un ordre est redonné avant la fin de la durée de la deuxième minuterie (durée qui depend des éléments C8 et P2), alors il se rallume à nouveau progressivement, sinon il s'eteind totalement. Les boutons poussoir sont oablé de telle sorte que l'on puisse avoir un éclairage continu en bloquant un de ces boutons. On adaptera le trias ainsi que son dissipateur aux puissances à colrjmander ; de plus il est possible de commander un eclairage alimenté par un reseau polyphasé en utilisant autant d'appareils (appareil qui fait l'objet de oe brevet) qu'il y a de phases.Operation t when the two timers are at rest the supply voltage is imposed, via the diode D3, at the terminal e- numbered 6 of the op-amp.Â2, so that the triao cannot be switched on,
When an order to launch the first timer is given, the previous voltage is no longer imposed at e- of A2, the potential of this terminal then gradually decreases as the capacitor C3 charges, this causes the conduction of the triac, with the charge of o3 until reaching 1800; this operating phase of the system is that which achieves progressive ignition. The lighting then stabilizes at its maximum value and thus remains for the entire duration fixed by the components C7 and P1.At the end of this duration, the first timer launches a second timer which, for its part, imposes a potential given to the terminal e- of A23 this potential is fixable by the resistors R6, R7 and R13, to act on the angle of conduction of the triao so that the lighting has a sufficient intensity to allow to distinguish in front of one while dimming this lighting enough to be able to see. If an order is given again before the end of the duration of the second timer (duration which depends on elements C8 and P2), then it will light up again gradually, otherwise it will go out completely. The push buttons are wired so that one can have continuous lighting by blocking one of these buttons. We will adapt the triassic and its dissipator to the powers to be ordered; moreover it is possible to control a lighting supplied by a polyphase network by using as many apparatuses (apparatus which is the object of oe patent) that there are phases.
I1 est possible d'avoir tout leStemps de minuterie utiles pour oette application, il suffit pour cela de jouer sur les constantes de temps C7*P1 et C8.P2. It is possible to have all the timer time useful for this application, it suffices to play on the time constants C7 * P1 and C8.P2.
