Den foreliggende opfindelse angår en anordning til styring af belysningsarmaturer og af den i krav l's indledning angivne art.The present invention relates to a device for controlling lighting fixtures and of the kind specified in the preamble of claim 1.
55
Ved en sådan styringsenhed søges opnået, at det enkelte armatur eller grupper af armaturer dæmpes eller kobles ud, når det nødvendige belysningsniveau i den pågældende del af rummet opretholdes af tilstrækkeligt dagslys/sollys. Dette vil have en gunstig virkning for indeklimaet, særlig i perioder med høj udetemperatur. Afbrudte lyskilder kan betyde en direkte besparelse af energiudgifter og kan i mange tilfælde reducere vedligeholdelsesomkostningerne.By such a control unit it is sought to achieve that the individual luminaire or groups of luminaires are dimmed or switched off when the necessary lighting level in that part of the room is maintained by sufficient daylight / sunlight. This will have a favorable effect on the indoor climate, especially during periods of high outdoor temperature. Interrupted light sources can directly save energy costs and can in many cases reduce maintenance costs.
For at opnå dette er det kendt at benytte lokale eller centrale styringsenheder, som kobler fra og til, eventuelt dæmper, armaturer eller grupper af armaturer på basis af fotocellemåling af belysningsstyrken på et referencested og/eller ved hjælp af et kontaktur. (Det er beskrevet i 20To achieve this, it is known to use local or central control units which switch off and on, optionally attenuators, luminaires or groups of luminaires based on photocell measurement of the illuminance at a reference point and / or by means of a contact clock. (It is described in 20
Elektro - Elektro-teknisk Tidsskrift 91, nr. 7, side 12-15, 11. april 1978, Lampetten nr. 3, 1977 samt brochuremateriale fra Notika A/S, DK-9400 Nørresundby, vedrørende produktet LUXSTAT (varemærke).) 25Electro - Electro-technical Journal 91, no. 7, pages 12-15, April 11, 1978, Lampetten no. 3, 1977 and brochure material from Notika A / S, DK-9400 Nørresundby, concerning the product LUXSTAT (trademark).) 25
Der findes også manuelle fjernbetjeningsenheder baseret på overføring af styresignaler via IR-stråling for lokal tilog frakobling eller dæmpning af armaturer eller grupper af armaturer (en sådan anordning er beskrevet i Siemens Elek- trodienst 26 (1984) hæfte 3, side 23). Sådanne enheder 30 findes også i kombination med de automatiske styresystemer, som er nævnt ovenfor, fx Philips Technical Information "Light" og "Integrated Function System".There are also manual remote control units based on transmitting control signals via IR radiation for local switching on or off of luminaires or groups of luminaires (such a device is described in Siemens Electro-Service 26 (1984) booklet 3, page 23). Such units 30 are also found in combination with the automatic control systems mentioned above, eg Philips Technical Information "Light" and "Integrated Function System".
De hidtil kendte automatiske styringssystemer benytter en 35 enkelt detektor (fotocelle) til at registrere pa et valgt referencested, enten summen af bidragene fra dagslys/sollys og den kunstige belysning i rummet eller belysningsstyrkenThe previously known automatic control systems use a single detector (photocell) to record at a selected reference point, either the sum of the contributions of daylight / sunlight and the artificial lighting in the room or the lighting intensity.

Fra GB patentskrift nr. 2.132.751 kendes et styresystem til styring af alle lyskilderne i et lokale under et, Lysde-5 tektoren indfanger lys fra en stor indfaldsvinkel. Et lignende styringssystem er beskrevet i US patentskrift nr. 4.236.101.From GB patent specification 2,132,751 a control system is known for controlling all the light sources in a room together, the Light detector captures light from a large angle of view. A similar control system is described in U.S. Patent No. 4,236,101.
I alle rum med dagslystilgang varierer belysningsstyrken for dagslyset alene stærkt fra sted til sted og desuden med tiden på grund af ændringer i solens position kombineret med rummets arkitektoniske udformning. Behovet for kunstig tillægsbelysning vil variere fra sted til sted og med tidspunktet i rummet. Det er således et væsentligt problem at finde et referencested for detektoren, som kan siges at være repræsentativt for rummet som helhed.In all rooms with daylight access, the lighting intensity of daylight alone varies greatly from place to place and in addition to time due to changes in the position of the sun combined with the architectural design of the room. The need for artificial additional lighting will vary from place to place and with the time in the room. Thus, it is a significant problem to find a reference point for the detector, which can be said to be representative of the space as a whole.
Det er yderligere et problem, at behovet for belysningsstyrke kan variere fra den ene arbejdsplads til den anden.Another problem is that the need for lighting power can vary from one workplace to another.
2020
Det er også en ulempe, at de eksisterende tekniske løsninger for automatisk styring kræver ekstra installationer af styresignalledere eller egne effektledere for lysinstallationerne. Dette medfører ekstra installationsomkostninger 25 ved nye anlæg og kostbare tillægsinstallationer ved anvendelse af eksisterende anlæg.It is also a disadvantage that the existing technical solutions for automatic control require additional installations of control signal conductors or own power conductors for the lighting installations. This entails additional installation costs 25 for new plants and expensive additional installations when using existing plants.
Formålet med opfindelsen er at anvise en anordning, som giver individuel automatisk styring af det enkelte lysarmatur 30 på en sådan måde, at styringen af det enkelte armatur ikke indvirker på den tilsvarende styring af andre armaturer i rummet, således at ustabilitet optræder. Det enkelte armaturs styringsenhed må kunne kalibreres individuelt i overensstemmelse med det belysningsniveau, som er hensigtsmæssigt for vedkommende del af rummet.The object of the invention is to provide a device which provides individual automatic control of the individual light fixtures 30 in such a way that the control of the individual luminaire does not affect the corresponding control of other luminaires in the room, so that instability occurs. The control unit of the individual luminaire must be individually calibrated in accordance with the lighting level appropriate for the part of the room.

krav 1.claim 1.
Opfindelsen muliggør lokal styring af lyskilderne i nye eller eksisterende anlæg uden ekstra omkostninger forbundet 5 med indføring af styringssignalledere eller separate effektledere for lysinstallationerne.The invention enables local control of the light sources in new or existing plants at no additional cost associated with the introduction of control signal conductors or separate power conductors for the light installations.

I fig. 3 er for det første vist de elektriske komponenter til et lysstofrørarmatur 11. Hovedelementet her er et lys-15 stofrør 20 med en starter 21, en reaktor 22 og en fasekondensator 23. Disse komponenter er på i og for sig kendt måde koblet sammen og til en indgangsterminal 24.In FIG. 3, firstly, the electrical components of a fluorescent lamp luminaire 11 are shown. The main element here is a fluorescent lamp 20 with a starter 21, a reactor 22 and a phase capacitor 23. These components are connected in a manner known per se. an input terminal 24.
Anordningen ifølge opfindelsen, som er betegnet generelt 20 med henvisningstal 14, omfatter en elektrisk del 25, som er seriekoblet mellem lysnettet og lysstofrørarmaturet 11, og en optisk del 15 med detektoren 16.The device according to the invention, generally designated 20 by reference numeral 14, comprises an electrical part 25 which is connected in series between the mains and the fluorescent lamp fixture 11, and an optical part 15 with the detector 16.
I fig. 3 er vist et udførelseseksempel for en lysenhed 25 25In FIG. 3 is an exemplary embodiment of a light unit 25

The operation of these parts will be described in more detail below, with the circuit being made up in principle known manner of available components.

- 5 - I fig. 4 er også vist den nærmere udformning af en teleskopisk, rørformet afblænding 17, som er fastgjort til et hus 31 uden for detektoren 16. I eksemplet er det optiske filter 18 monteret over den indre åbning i afblændingen 17.In FIG. 4 is also shown the configuration of a telescopic tubular aperture 17 which is attached to a housing 31 outside the detector 16. In the example, the optical filter 18 is mounted over the inner aperture of the aperture 17.
55
Huset 31 kan benyttes til montering på allerede eksisterende armaturer, til uafhængig montering eller til indbygning.The housing 31 can be used for mounting on pre-existing luminaires, for independent mounting or for installation.
For at opnå formålet med opfindelsen er det nødvendigt, at ^ målingen af lyset og behandlingen af det signal, som registreres, sker på en eller flere af følgende måder: 1. Det optiske filter 18 udformes for at transmittere lys i en del af spektret, hvor forholdet mellem det optiske ^ egensignal og det optiske hovedsignal, nemlig skabt af fremmed lys, er et minimum. Dette vil i et eksempel kunne betyde, at der bruges et filter, som lader lys slippe igennem nær det infrarøde område.In order to achieve the object of the invention, it is necessary that the measurement of the light and the processing of the signal being recorded take place in one or more of the following ways: 1. The optical filter 18 is designed to transmit light in a portion of the spectrum; where the ratio of the optical ^ intrinsic signal to the principal optical signal, namely created by foreign light, is a minimum. In an example, this could mean using a filter that lets light pass through near the infrared area.
20 2. Detektoren 16 kan være fremstillet af et materiale med særlig høj spektral følsomhed i det område, som er nævnt ovenfor. Dette bidrager også til, at der først og fremmest måles fremmed lysindfald i måleområdet.2. The detector 16 may be made of a material of particularly high spectral sensitivity in the region mentioned above. This also contributes to the fact that, first and foremost, foreign light is measured in the measurement area.
25 3. Den elektroniske kreds 29 indeholder komponenter, som beregner hovedsignalet, altså komponenten af fremmed lys Ed, på grundlag af den registrerede variation af belysningsstyrken i løbet af vekselstrømsperioden, som det er vist i fig. 2.25 3. The electronic circuit 29 contains components which calculate the main signal, that is, the component of foreign light Ed, on the basis of the recorded variation of the illumination during the AC period, as shown in FIG. 2nd
3030
Ifølge opfindelsen er det muligt med en styringsenhed at sikre en rigtig belysningsstyrke i armaturets belysningsområde ved en individuel kalibrering. Dette indebærer, at kun det antal armaturer, som er nødvendig for at opretholde 35 denne rigtige belysningsstyrke, er i drift til enhver tid.According to the invention, it is possible with a control unit to ensure a correct illuminance in the illumination area of the luminaire by an individual calibration. This means that only the number of luminaires needed to maintain this true illuminance is in operation at all times.
Der skal nu gives en mere detaljeret beskrivelse af signal-A more detailed description of the signal-

- 6 - behandlingen i styrekredsen 29.- 6 - processing in the control circuit 29.
Det elektriske signal fra detektoren indeholder en tilnær-5 met konstant andel, som kan relateres til dagslys/sollyskomponenten Ed i belysningsstyrken på målestedet, og en andel, som kan relateres til belysningsstyrken E , som skyl-des elektriske lyskilder. Dette er illustreret i fig. 2.The electrical signal from the detector contains an approximate constant proportion which can be related to the daylight / sunlight component Ed in the illumination power at the measurement location, and a proportion which can be related to the illumination power E due to electric light sources. This is illustrated in FIG. 2nd
j^q Det elektriske signal forstærkes. Under antagelse af en karakteristisk værdi for forholdet E,. . /E, kan andelen E^ filtreres bort, og den resterende del af E^min gøres mindst mulig, i princippet fjernes helt. Det endelige elektriske signal indeholder således alene information om -^5 komponenten Εβ og en eventuel rest af E^. Dette viderebe-handles i komparatoren.j ^ q The electrical signal is amplified. Assuming a characteristic value for the ratio E,. . / E, the proportion of E ^ can be filtered out and the remaining part of E ^ min made as small as possible, in principle completely removed. Thus, the final electrical signal contains only information about the - ^ 5 component Εβ and any residual E ^. This is further processed in the comparator.
Forstærkerkredsens tidsforsinkelse hindrer, at tilfældige varitioner af kort varighed i belysningsstyrken på måleste-20 det medfører til- eller frakobling af armaturet.The time delay of the amplifier circuit prevents random variations of short duration in the illuminance of the measurement site causing the luminaire to be switched on or off.
Det endelige elektriske signal bliver i komparatorkredsen sammenlignet med manuelt indstillelige niveauer for belysningsstyrke og hysterese. Niveauet for hysteresen indstil-25 les med et potentiometer 32. Hysteresen virker således, at niveauet for belysningsstyrken, som fører til frakobling af armaturet, ligger højere end det tilsvarende, som medfører tilkobling. Derved undgås, at der opstår gensidig påvirkning og ustabilitet for det enkelte armatur og armaturerne 20 indbyrdes. Signalet fra komparatorkredsen 28 aktiverer den elektroniske afbryder 27 ud eller ind.The final electrical signal is compared in the comparator circuit with manually adjustable levels of illuminance and hysteresis. The level of the hysteresis is set with a potentiometer 32. The hysteresis acts so that the level of illumination which leads to disconnection of the luminaire is higher than the corresponding one which results in connection. This avoids the mutual influence and instability of the individual luminaire and the luminaires 20 among themselves. The signal from the comparator circuit 28 activates the electronic switch 27 out or in.
Opfindelsen kan modificeres på forskellige måder i forhold til eksemplet. Den elektroniske afbryder 27 kan erstattes 25 med en kreds, som kan styre lysarmaturet trinløst eller i trin, fx en fasestyret triac. På denne måde kan der foretages en endda mere nøjagtig tilpasning af belysningsstyrken.The invention can be modified in various ways relative to the example. The electronic switch 27 can be replaced 25 by a circuit which can control the light fixture infinitely or in stages, for example a phase controlled triac. In this way, an even more accurate adjustment of the illuminance can be made.

Anordningen ifølge opfindelsen vil i udgangspunktet væreThe device according to the invention will basically be
egnet til brug ved individuelle belysningsarmaturer. Isuitable for use with individual lighting fixtures. IN
princippet kan den imidlertid udnyttes også for grupper på to eller flere armaturer, som styres under et. I dette 5 tilfælde skal anordningen have en central placering i det samlede lysfelt fra armaturerne. Fx kan en række armaturer langs en vinduesvæg styres for sig, og armaturer, som er placeret længere inde i rummet, styres for sig.however, it can also be used for groups of two or more luminaires, which are controlled together. In this case, the device must have a central location in the total light field from the luminaires. For example, a number of luminaires along a window wall can be individually controlled and luminaires located further inside the room can be individually controlled.

Styringssystemet ifølge opfindelsen kan også kombineres med et system for til- og frakobling ved hjælp af en IRT-sen-der, som modsvarer det, som er beskrevet under omtalen af kendt teknik i det foregående.The control system according to the invention can also be combined with a system for switching on and off by means of an IRT transmitter which corresponds to that described in the prior art discussion.
