Description

Dispositif pour créer une ambiance lumineuse variable La présente invention concerne un dispositif permettant de faire décroître de façon imperceptible à l'oeil l'intensité lumineuse d'une lampe d'éclairage afin de créer une ambiance lumineuse comparable au coucher du soleil , favorable en elle même à l'endormissement et renforcée par le fait qu'elle libère l'utilisateur du souci d'éteindre la lumière et qu' elle lui évite de se trouver brutalement plongé dans l'obscurité , associé à un moyen permettant à tout moment de ramener l'intensité lumineuse de la lampe à son niveau initial en réponse à des sons répondant aux critères de discrimination justifiant cette réactivation . The present invention relates to a device making it possible to decrease the light intensity of an illumination lamp imperceptibly to the eye in order to create a favorable light environment comparable to sunset, even when falling asleep and reinforced by the fact that it frees the user from the worry of turning off the light and that it saves him from being brutally plunged into darkness, associated with a means allowing at any time to bring back the light intensity of the lamp at its initial level in response to sounds meeting the discrimination criteria justifying this reactivation.
La peur de l'obscurité chez l'enfant et chez certains adultes est éliminée traditionnellement en laissant prés du sujet une source lumineuse qui est éteinte ou non après son endormissement.Par ailleurs.il est connu qu' une lumière s'éteignant progressivement a un effet bénéfique sur l'endormissement,comme le coucher du soleil sur l'endormissement du monde animal ou de l'homme par le passé.Par contre,un enfant,un malade,peuvent se réveiller la nuit en pleurant ou en gémissant, dans ce cas il est utile que ces pleurs ou ces gémissements activent le réallumage de la lampe d'éclairage afin de les rassurer et d'éviter ainsi à une tierce personne de le /faire. Des dispositifs permettant de faire décroître lentement l'intensité lumineuse d'une lampe d'éclairage ont déjà été décrits : (MUND0 ELECTRONICO n° 58, décembre 1976,page 58,"Graduador progresivo automatico de luz "; ELEKTRO TECHNIK, vol.61,n°4, février 1979,page 54 ," Schlummerschalter mit MOS-Dimmer "; ELECTRONIQUE INDUSTRIELLE,n°274,octobre 1979,page 68 "Gradateur de lumière en CMOS "). De même un tel variateur automatique associé à un microphone permettant de réactiver la lampe d'éclairage lorsque le niveau sonore dépasse un seuil prédéterminé a déjà été décrit : ( Brevet US 3 898 383 , 5 Août 1975 , Charles HERBITS ) . Ce dernier dispositif présente l'inconvénient de réactiver la lampe d'éclairage dès que le niveau sonore dépasse un seuil prédéterminé . La réactivation se fera donc sans distinction d'origine ou de nature du son , c'est ainsi qu'une porte qui claque , un objet qui tombe , un éternuement et d'une manière générale tout bruit quelle qu'en soit l'origine réactivera la lampe pourvu que son amplitude dépasse le seuil de déclenchement . Un tel dispositif peut même aller à l'encontre du but recherché car le réallumage brutal peut alors réveiller la personne ou l'enfant endormi .The fear of darkness in children and in some adults is traditionally eliminated by leaving near the subject a light source which may or may not be extinguished after falling asleep. Furthermore, it is known that a light which gradually goes out at a beneficial effect on falling asleep, like the sunset on the drowsiness of the animal world or the man in the past. On the other hand, a child, a patient, can wake up at night by crying or moaning, in this In this case, it is useful for these crying or groans to activate the re-ignition of the lighting lamp in order to reassure them and thus prevent a third person from doing so. Devices allowing the light intensity of a lighting lamp to slowly decrease have already been described: (MUND0 ELECTRONICO n ° 58, December 1976, page 58, "Graduador progresivo automatico de luz"; ELEKTRO TECHNIK, vol.61 , n ° 4, February 1979, page 54, "Schlummerschalter mit MOS-Dimmer"; ELECTRONICS INDUSTRIAL, n ° 274, October 1979, page 68 "Dimmer of light in CMOS"). Similarly, such an automatic dimmer associated with a microphone enabling the lighting lamp to be reactivated when the sound level exceeds a predetermined threshold has already been described: (US Patent 3,898,383, August 5, 1975, Charles HERBITS). The latter device has the drawback of reactivating the lighting lamp as soon as the sound level exceeds a predetermined threshold. The reactivation will therefore be done without distinction of origin or nature of the sound, this is how a door slams, an object which falls, a sneeze and in general any noise whatever its origin will reactivate the lamp as long as its amplitude exceeds the triggering threshold. Such a device can even go against the desired goal because the sudden re-ignition can then wake the sleeping person or child.
Le dispositif selon l'invention permet d'éviter cet inconvénient , il comporte pour cela , associé à un variateur automatique permettant de faire décroître sur un temps prédéterminé l'intensité lumineuse d'une lampe d'éclairage d'un niveau initial prédéterminé jusqu'à l'extinction , un moyen de discrimination des sons pour déterminer la nature de ces sons afin de ramener l'intensité lumineuse à son niveau initial en réponse à des sons répondant aux critères de discrimination . Les critères de discrimination permettant de sélectionner les sons justifiant de ramener l'intensité lumineuse à son niveau initial peuvent être le spectre de ces sons et/ou la durée et/ou la répétition de ces sons . Ainsi les bruits parasites tels que ceux cités plus haut ne provoqueront pas l'allumage intempestif de la lampe d'éclairage alors qu'avec des critères de discrimination correctement choisis , des bruits comme les pleurs ou les cris d'un enfant , les gémissements d'un malade provoqueront le retour de l'éclairage à son niveau initial . Lorsque ces bruits cesseront , le variateur automatique fera de nouveau décroître de façon imperceptible l'intensité lumineuse de son niveau inital jusqu'à l'extinction pendant le temps prédéterminé . Le dispositif ainsi réalisé , placé dans la chambre d'un enfant , d'un malade , d'une personne âgée ou angoissée aura ainsi pour finalité d'être entièrement et exclusivement à leur disposition . C'est précisément l'intérêt d'un tel dispositif que d'être attentif à l'endormissement et au sommeil physiologique . Un enfant peut éternuer , cogner son berceau , un véhicule peut en passant dans la rue faire vibrer les vitres de la fenêtre , une porte peut claquer dans la pièce voisine , tout cela ne justifie pas de réactiver la lampe . Mais si l'enfant pleure ou crie à la suite d'un cauchemar ou s'il émet des gémissements parce qu'il souffre cela justifie de réactiver la lampe et il en va de même pour un malade . Le dispositif comporte par ailleurs un moyen de réglage du niveau initial de la lampe d'éclairage , un moyen de réglage du temps nécessaire pour obtenir l'extinction de la lampe et une commande manuelle permettant de ramener l'intensité lumineuse à son niveau initial . D'autre part pour éviter un inconvénient lié aux variateurs automatiques cités plus haut qui est de fixer la vitesse de décroissance de l'intensité lumineuse et non le temps pour obtenir l'extinction , ce qui se traduit par un temps d'autant plus court que le niveau initial de l'intensité lumineuse est bas , le dispositif selon l'invention comporte un moyen pour compenser cet effet , c'est à dire que le temps nécessaire pour que l'intensité lumineuse de la lampe passe du niveau initial à l'extinction est maintenu constant quel que soit le niveau initial . Ceci est obtenu en réduisant la vitesse de décroissance de l'intensité lumineuse proportionnellement à la réduction de l'intensité lumineuse correspondant au niveau initial choisi . Une variante du dispositif selon l'invention permet de ramener l'inten site lumineuse de la lampe progressivement; a une viτesse preaetermlnee jusqu'au niveau initial prédéterminé en réponse à des sons répondant aux critères de discrimination .The device according to the invention makes it possible to avoid this drawback, it comprises for this, associated with an automatic dimmer making it possible to decrease over a predetermined time the luminous intensity of a lighting lamp from an initial predetermined level up to at extinction, a sound discrimination means for determining the nature of these sounds in order to bring the light intensity to its initial level in response to sounds meeting the discrimination criteria. The discrimination criteria for selecting the sounds justifying bringing the light intensity to its initial level can be the spectrum of these sounds and / or the duration and / or repetition of these sounds. Thus, parasitic noises such as those mentioned above will not cause the lighting lamp to light up unexpectedly, whereas with correctly selected discrimination criteria, noises such as the crying or the cries of a child, the groans of 'a patient will cause the lighting to return to its initial level. When these noises cease, the automatic dimmer will again make the light intensity decrease imperceptibly from its initial level until it goes out for the predetermined time. The device thus produced, placed in the room of a child, a patient, an elderly or anxious person will thus have the purpose of being entirely and exclusively at their disposal. It is precisely the interest of such a device to be attentive to falling asleep and physiological sleep. A child can sneeze, bang his cradle, a vehicle can while passing in the street make vibrate the panes of the window, a door can slam in the next room, all that does not justify reactivating the lamp. But if the child cries or shouts following a nightmare or if he emits groans because he suffers that justifies reactivating the lamp and the same goes for a sick person. The device also comprises a means for adjusting the initial level of the lighting lamp, a means for adjusting the time necessary to obtain the extinction of the lamp and a manual control making it possible to return the light intensity to its initial level. On the other hand, to avoid a drawback linked to the automatic dimmers mentioned above which is to fix the speed of decrease of the light intensity and not the time to obtain the extinction, which results in an even shorter time. that the initial level of the light intensity is low, the device according to the invention comprises means to compensate for this effect, that is to say that the time necessary for the light intensity of the lamp to go from the initial level to 1 extinction is kept constant whatever the initial level. This is achieved by reducing the rate of decrease in light intensity in proportion to the reduction in light intensity corresponding to the initial level chosen. A variant of the device according to the invention makes it possible to reduce the intensity light site of the lamp gradually; has a preaetermlnee speed to the initial predetermined level in response to sounds meeting the discrimination criteria.
La figure 1 est le schéma synoptique de la présente invention . La figure 2 est le schéma de principe d'une forme de réalisation de la présente invention .Figure 1 is the block diagram of the present invention. Figure 2 is the block diagram of an embodiment of the present invention.
Sur la figure 1 , on peut voir , alimenté par une source de courant alternatif (1) , en série avec une lampe d'éclairage (2) et un filtre antiparasite (3) , un variateur de lumière automatique (4) , comportant un moyen de réglage de l'intensité lumineuse initiale du maximum à l'extinction (5) et un moyen de réglage du temps nécessaire pour obtenir l'extinction (6) . Ce variateur automatique peut à tout moment ramener l'intensité lumineuse à son niveau initial déterminé par le réglage (5) lorsque la commande manuelle (7) est actionnée ou lorsque les sons recueillis et transformés en signaux BF par le microphone (8) auront pu traverser le filtre (9) dont la courbe de réponse correspond au spectre des sons justifiant de réactiver la lampe (2) et qu'une fois redressés par le détecteur (10) la durée et/ou la répétition de ces sons transformés en signaux BF auront permis une charge suffisante de l'intégrateur (11) .In Figure 1, we can see, powered by an alternating current source (1), in series with a lighting lamp (2) and a noise filter (3), an automatic light dimmer (4), comprising a means for adjusting the initial light intensity of the maximum at extinction (5) and means for adjusting the time necessary to obtain extinction (6). This automatic dimmer can at any time bring the light intensity to its initial level determined by the setting (5) when the manual control (7) is actuated or when the sounds collected and transformed into LF signals by the microphone (8) have been able cross the filter (9) whose response curve corresponds to the spectrum of sounds justifying to reactivate the lamp (2) and that once rectified by the detector (10) the duration and / or the repetition of these sounds transformed into LF signals have allowed a sufficient load of the integrator (11).
Dans une variante du dispositif selon l'invention , chaque fois que l'intégrateur (11) a atteint une charge suffisante ou lorsque sa charge se trouve maintenue , le variateur automatique (4) ramène progressivement à une vitesse prédéterminée l'intensité lumineuse au niveau initial réglé par (5) .In a variant of the device according to the invention, each time the integrator (11) has reached a sufficient charge or when its charge is maintained, the automatic dimmer (4) gradually returns the light intensity to the predetermined speed. initial set by (5).
Sur la figure 2 , on trouve en série avec l'alimentation en courant alternatif (1) une lampe d'éclairage (2) et le dispositif selon l'invention (20) . Le dispositif (20) étant lui même composé d'un filtre antiparasite (3) , d'une alimentation en courant continu (12) obtenue par redressement d'une partie du courant d'alimentation de la lampe (2) , ce courant étant suffisamment faible pour ne pas allumer la lampe (2), et du triac (13) qui permet de doser le courant traversant la lampe (2). Chaque fois que le circuit (14) détecte le passage à zéro du courant alternatif, le transistor (15) est rendu conducteur et décharge à travers la diode (17) le condensateur (16) . Le condensateur (16) se recharge ensuite à travers les résistances (18) dont le réglage de la valeur (5 ) permet de déterminer le niveau initial de l'intensité lumineuse de la lampe d'éclairage (2) . Ceci est obtenu en bloquant le décompteur (21) jusqu'à ce que la tension aux bornes du condensateur (16) ait atteint le seuil de l'inverseur (22) . Pendant que le décompteur (21) est bloqué et après le passage à zéro du courant alternatif , le transistor (15) est bloqué , les diodes (17) et (23) sont bloquées , la sortie de l'inverseur (22) est à un niveau logique un car la condensateur (16) est en train de se recharger , l'inverseur (24) reçoit sur son entrée ce niveau logique un et prêsente donc sur sa sortie un niveau logique zéro qui est appliqué sur l'entrée de chargement du décompteur (21) permettant à ce dernier de se positionner à la valeur présentée sur ses entrées 0 à 7 par les sorties 0 à 7 du compteur (25) . Lorsque le condensateur (16) est chargé , la sortie de l'inverseur (22) passe à zéro et celle de l'inverseur (24) passe à un. Le décompteur (21) est alors libéré et peut décompter les Impulsions d'horloge fournies par l'oscillateur (26) . Lorsque le nombre d'Impulsions fourni par l'oscillateur (26) correspond à la valeur fournie par le compteur (25) , le décompteur (21) passe à zéro et génère alors une impulsion sur sa sortie "détect.zéro" qui est utilisée pour commander l'amorçage du triac (13) par l'intermédiaire du transistor (27) . lorsque le contenu du compteur (25) est zéro , la valeur chargée dans le décompteur (21) sera aussi zéro et le retard introduit par le décompteur (21) dans l'amorçage du triac (13) sera nul . Le retard entre le passage à zéro du courant alternatif et l'amorçage du triac (13) sera uniquement du au temps de recharge du condensateur (16) qui détermine ainsi le niveau initial de la lampe (2) . Le compteur (25) est ensuite très lentement incrémenté par les impulsions fournies par l'oscillateur-diviseur (28) dont la fréquence peut être réglée par (6) afin de déterminer le temps nécessaire pour obtenir l'extinction de la lampe (2) . Pour que le réglage (6) agisse bien sur le temps pour obtenir l'extinction de la lampe (2) et que ce temps soit indépendant du niveau initial réglé par (5), l'oscillateur-diviseur (28) est bloqué par la diode (29) lorsque la sortie de l'inverseur (24) est à zéro c'est à dire lorsque le condensateur (15) se recharge . Le blocage de l'oscillateur-diviseur (28) va donc être proportionnel au temps nécessaire pour que le condensateur (16) se recharge et le compteur (25) sera incrémenté d'autant plus lentement que le niveau initial de la lampe (2) sera bas . Lorsque le compteur (25) arrive à sa capacité maximum , sa sortie 8 passe au niveau logique un ce qui produit le blocage de l'oscillateur-diviseur (28) par maintien à zéro et le blocage du décompteur (21) par maintien à un . La lampe (2) sera alors maintenue éteinte et cela jusqu'à ce que le compteur (25) soit remis à zéro . La remise à zéro du compteur (25) pourra être faite par effleurement de la touche (7) ou lorsque les sons captés par le microphone (8) seront identifiés comme étant des pleurs ou des cris . Les critères de discrimination choisis pour permettre d'identifier des pleurs ou des cris sont dans cette forme de réalisation de la présente invention , la hauteur des sons qui est mise en évidence par un filtre passe haut (9) constitué de l'amplificateur opérationnel (31) associé aux résistances (32) et (33) et au condensateur (34) , et la durée et la fréquence de répétition de ces sons mis en évidence par un semi-intégrateur (11) constitué du condensateur (38) associé aux résistances (39) et (40) . Lorsque la tension aux bornes du condensateur (38) atteint le seuil de basculement de l'inverseur (41) , la sortie de l'inverseur (41) passe au niveau logique un et le compteur (25) est remis à zéro ce qui entraine l'allumage de la lampe (2) au niveau initial réglé par (5) . La constante de temps de charge du semi-intégrateur (11) est choisie de façon à autoriser l'allumage de la lampe (2) si des cris ou des pleurs continus d'une durée d'au moins deux secondes pouvant aller jusqu'à cinq secondes pour des cris ou des pleurs intermittents . La constante de temps de décharge du semi-intégrateur (11) est choisie de façon à ne pas provoquer le réallumage de la lampe (2) si des sons ayant pu franchir le filtre (9) ont un rapport cyclique inférieur à un dixième . La commande de l'intégrateur (11) est effectuée par le transistor (37) lui même commandé par la sortie du détecteur (10) constitué d'un comparateur qui bascule en présence des alternances négatives du signal BF issu du filtre (9) . La sensibilité du comparateur peut être ajustée par le potentiomètre (36) . Dans une variante du dispositif selon l'invention le compteur (25) est un compteur-décompteur qui est incrémenté par les impulsions fournies par l'oscillateur-diviseur (28) en l'absence de cris ou de pleurs afin d'obtenir la décroissance de l'intensité lumineuse et qui décompte les impulsions fournies par l'oscillateur-diviseur (28) en présence de cris ou de pleurs afin de ramener progressivement l'intensité lumineuse de la lampe (2) au niveau initial réglé par (5) à une vitesse réglée par (35) .In Figure 2, there is in series with the AC power supply (1) a lighting lamp (2) and the device according to the invention (20). The device (20) itself being composed of a noise filter (3), of a direct current supply (12) obtained by rectifying part of the supply current of the lamp (2), this current being low enough not to light the lamp (2), and triac (13) which allows the current flowing through the lamp (2) to be measured. Each time the circuit (14) detects the zero crossing of the alternating current, the transistor (15) is made conductive and discharges through the diode (17) the capacitor (16). The capacitor (16) is then recharged through the resistors (18) whose value setting (5) makes it possible to determine the initial level of the light intensity of the lighting lamp (2). This is achieved by blocking the downcounter (21) until the voltage across the capacitor (16) has reached the threshold of the inverter (22). While the down-counter (21) is blocked and after the zero crossing of the alternating current, the transistor (15) is blocked, the diodes (17) and (23) are blocked, the output of the inverter (22) is at a logic level one because the capacitor (16) is in being recharged, the inverter (24) receives on its input this logic level one and therefore presents on its output a zero logic level which is applied to the loading input of the down-counter (21) allowing the latter to position itself to the value presented on its inputs 0 to 7 by the outputs 0 to 7 of the counter (25). When the capacitor (16) is charged, the output of the inverter (22) goes to zero and that of the inverter (24) goes to one. The down-counter (21) is then released and can count down the clock pulses supplied by the oscillator (26). When the number of pulses supplied by the oscillator (26) corresponds to the value supplied by the counter (25), the down-counter (21) goes to zero and then generates a pulse on its "zero detect" output which is used to control the initiation of the triac (13) via the transistor (27). when the content of the counter (25) is zero, the value loaded into the down-counter (21) will also be zero and the delay introduced by the down-counter (21) in the initiation of the triac (13) will be zero. The delay between the zero crossing of the alternating current and the ignition of the triac (13) will only be due to the recharging time of the capacitor (16) which thus determines the initial level of the lamp (2). The counter (25) is then very slowly incremented by the pulses supplied by the oscillator-divider (28) whose frequency can be adjusted by (6) in order to determine the time necessary to obtain the extinction of the lamp (2) . So that the setting (6) acts on the time to obtain the extinction of the lamp (2) and that this time is independent of the initial level set by (5), the oscillator-divider (28) is blocked by the diode (29) when the output of the inverter (24) is zero, that is to say when the capacitor (15) is recharging. The blocking of the oscillator-divider (28) will therefore be proportional to the time necessary for the capacitor (16) to recharge and the counter (25) will be incremented all the more slowly as the initial level of the lamp (2) will be low. When the counter (25) reaches its maximum capacity, its output 8 goes to logic level one which produces the blocking of the oscillator-divider (28) by holding to zero and the blocking of the down counter (21) by holding to a . The lamp (2) will then be kept off and this until the counter (25) is reset to zero. The counter (25) can be reset to zero by pressing the key (7) or when the sounds picked up by the microphone (8) are identified as crying or shouting. The discrimination criteria chosen to identify crying or shouting are in this embodiment of the present invention, the pitch of the sounds which is highlighted by a high pass filter (9) consisting of the operational amplifier (31) associated with the resistors (32) and (33) and with the capacitor (34), and the duration and frequency of repetition of these sounds highlighted by a semi-integrator (11) consisting of the capacitor (38) associated with the resistors (39) and (40). When the voltage across the capacitor (38) reaches the switching threshold of the inverter (41), the output of the inverter (41) goes to logic level one and the counter (25) is reset to zero, which causes switching on the lamp (2) at the initial level set by (5). The charge time constant of the semi-integrator (11) is chosen so as to authorize the lighting of the lamp (2) if cries or continuous crying lasting at least two seconds which can go up to five seconds for intermittent cries or crying. The discharge time constant of the semi-integrator (11) is chosen so as not to cause the lamp (2) to re-ignite if sounds which may have passed through the filter (9) have a duty cycle of less than one tenth. The integrator (11) is controlled by the transistor (37) itself controlled by the output of the detector (10) consisting of a comparator which switches in the presence of negative half-waves of the LF signal from the filter (9). The sensitivity of the comparator can be adjusted by the potentiometer (36). In a variant of the device according to the invention, the counter (25) is an up-down counter which is incremented by the pulses supplied by the oscillator-divider (28) in the absence of shouts or crying in order to obtain the decrease of the light intensity and which counts the pulses supplied by the oscillator-divider (28) in the presence of cries or tears in order to gradually reduce the light intensity of the lamp (2) to the initial level set by (5) at a speed set by (35).
