Description

20 25 30 Ešfl E59 vänds, eller rapid-startkoppling och semiresonanskoppling, i vilka glimtända- re saknas. l dessa kopplingar ingår även olika fonner av reaktorer. Ytterligare en kopplingsform är en sk HF-koppling (högfrekvenskoppling), i vilken ett HF- don är anslutet till en fasledning och en 0-ledning tillhörande ett elnät eller en annan strömkälla. Den från HF-donet utgående matningen till lysröret utgörs i sin tur av två kontaktledningar, vilka är anslutna till var sin kontaktsockel eller motsvarande organ. Dessa kontaktledningar är i drift växelvis spänningsfö- rande. l denna text görs ingen skillnad på om kontaktsocklarna är anslutna direkt eller indirekt genom reaktorer eller HF-don till fasledning respektive 0- ledning. Alla ledningar, som matar ström till belysningsarmaturens kontakt- socklar, benämns nedan ”kontaktledningañ Ett gasfyllt lysrör leder inte ström förrän en spänning lagts över dess båda kontaktändar. En lysdiodstav uppvisar däremot en strömledande förbindning mellan sina ändar, vilket kan medföra att åtminstone ett kontakt- organ i den fria änden av staven skulle kunna bli strömförande och välla personskada om staven skulle föras in snett i en kontaktsockel så att dess ena ände kom i kontakt med en spänningsförande kontaktledning och dess andra ände blev åtkomlig för beröring. Såväl lysdiodstavar som andra belysningsanordningar, som uppvisar strömledande förbindningar, benämns nedan ”lampor” . 20 25 30 Ešfl E59 is reversed, or rapid-start coupling and semi-resonant coupling, in which glow plugs are missing. These connections also include various forms of reactors. Another form of connection is a so-called HF connection (high-frequency connection), in which an HF device is connected to a phase line and an O-line belonging to an electricity network or another power source. The supply to the fluorescent lamp emanating from the HF device in turn consists of two contact wires, which are each connected to a separate socket or corresponding member. These overhead contact lines are alternately live in operation. In this text, no distinction is made between whether the contact sockets are connected directly or indirectly through reactors or HF ballasts to phase line and 0 line, respectively. All wires that supply power to the luminaires' contact sockets are referred to below as “contact wire” A gas-filled fluorescent lamp does not conduct current until a voltage has been applied across its two contact ends. An LED rod, on the other hand, has a current-conducting connection between its ends, which can mean that at least one contact member at the free end of the rod could become live and cause personal injury if the rod were inserted obliquely into a contact socket so that one end of it came into contact. with a live contact wire and its other end became accessible for touch. Both LED rods and other lighting devices, which have conductive connections, are hereinafter referred to as "lamps".

Sammanfattning av uppfinningen Ett ändamål med uppfinningen är att åstadkomma en skyddsanordning för en belysningsarmatur som gör att en lampa som uppvisar en ledningsförbindning mellan sina båda ändar, exempelvis en lysdiodstav, kan monteras och demonteras i arrnaturen utan risk för personskada. Uppfinningen omfattar sålunda en skyddsanordning för en belysningsarmatur, vilken armatur är avsedd att uppbära minst en i huvudsak stavformig lampa, vars vardera ände uppvisar minst ett kontaktorgan, varvid lampan vidare uppvisar ett eller flera ljusavgivande organ, som är elektriskt anslutna mellan kontaktorganen i respektive ändar, varvid lampans ena ände är avsedd att anslutas till en första kontaktsockel och andra ände är avsedd att anslutas till en andra kontaktsockel i belysningsarmaturen, och varvid den 10 15 20 25 30 53? E93 första kontaktsockeln står i förbindelse med en första, och den andra kontakt- sockeln står i förbindelse med en andra kontaktledning för matning av ström till lampan. Lampan innefattar minst en strömbrytare, som bringas att sluta strömkretsen med de ljusavgivande organen när lampans båda ändar samtidigt förs in i respektive kontaktsocklar.Summary of the invention An object of the invention is to provide a protection device for a luminaire which enables a lamp having a wiring connection between its two ends, for example an LED rod, to be mounted and disassembled in the luminaire without risk of personal injury. The invention thus comprises a protection device for a lighting luminaire, which luminaire is intended to support at least one substantially rod-shaped lamp, each end of which has at least one contact member, the lamp further having one or two light emitting means, which are electrically connected between the contact means at respective ends. wherein one end of the lamp is intended to be connected to a first contact socket and the other end is intended to be connected to a second contact socket in the luminaire, and wherein it is 10 15 20 25 30 53? The E93 first socket is connected to a first, and the second socket is connected to a second socket for supplying power to the lamp. The lamp comprises at least one switch, which is caused to close the circuit with the light emitting means when both ends of the lamp are simultaneously inserted into the respective sockets.

En strömbrytare kan vara anordnad vid vardera änden av lampan. Respektive strömbrytare kan uppvisa ett eller flera brytarorgan, som indikerar när lampan är införd i respektive kontaktsocklar. Nämnda ett eller flera brytarorgan kan utgöras av ett eller flera från lampan utskjutande tryckorgan, som är förskjutbara in i lampan och som är anordnade att sluta strömkretsen med de ljusavgivande organen.A switch can be arranged at each end of the lamp. The respective switches can have one or more switch means, which indicate when the lamp is inserted in the respective sockets. Said one or more switch means may be constituted by one or more pressure means projecting from the lamp, which are displaceable into the lamp and which are arranged to close the circuit with the light-emitting means.

Tryckorganen kan vara anordnade på minst en brytarkropp, som är anordnad att förskjutas in i lampan när tryckorganen bringas i kontakt med respektive kontaktsockel eller kontaktsocklar. Brytarkroppen kan uppbära minst en styrtapp, som är anordnad att löpa in i minst ett styrspår när lampans båda ändar samtidigt förs in i respektive kontaktsocklar.The pressure means may be arranged on at least one switch body, which is arranged to be displaced into the lamp when the pressure means are brought into contact with the respective contact base or contact sockets. The switch body can support at least one guide pin, which is arranged to run into at least one guide groove when both ends of the lamp are simultaneously inserted into the respective contact sockets.

Styrtappens inåtgående rörelse kan vara anordnad att stoppas av minst en styrklack om den ena av lampans ändar förs in i respektive kontaktsockel före den andra.The inward movement of the guide pin can be arranged to be stopped by at least one guide lug if one of the ends of the lamp is inserted into the respective contact base before the other.

Företrädesvis utgörs lampan av en lysdiodstav. Lysdiodstaven innefattar en elektrisk drivenhet, som dels är ansluten till det första kontakt- organet, dels är ansluten till det andra kontaktorganet via en elektrisk led- ning, till vilken ett antal ljusavgivande organ i form av lysdioder är anslutna. I detta fall kan strömbrytaren vara sammanbyggd med drivenheten och anord- nad vid lysdiodstavens ena ände. I ett alternativt utförande kan en strömbry- tare vara anordnad vid vardera änden på lampan/lysdiodstaven och den eventuella drivenheten i fallet med lysdiodstaven vara placerad skild från dessa strömbrytare.Preferably, the lamp consists of an LED rod. The LED rod comprises an electric drive unit, which is partly connected to the first contact means, and partly connected to the second contact means via an electrical line, to which a number of light-emitting means in the form of LEDs are connected. In this case, the switch can be integrated with the drive unit and arranged at one end of the LED rod. In an alternative embodiment, a switch may be arranged at each end of the lamp / LED rod and the possible drive unit in the case of the LED rod may be located separately from these switches.

Beskrivning av utföringsformer En singelkopplad belysningsarrnatur1 för lysrör, som visas ifigur 1, och som är avsedd att fästas t ex vid ett undertak eller på en vägg, uppbär en lysdiodstav 2 försedd med ett eller flera kontaktorgan i sin vardera ände.Description of embodiments A single-coupled lighting fixture1 for fluorescent lamps, shown in Figure 1, which is intended to be attached, for example, to a suspended ceiling or to a wall, carries an LED rod 2 provided with one or two contact members at each end.

Lysdiodstaven 2 är anordnad mellan två kontaktsocklar 1.1, 1.2 och innefattar en elektrisk drivenhet 2.1, som är ansluten till en första kontakt- ledning, i detta fall en fasledning från en reaktor 3, via den vänstra kontakt- sockel 1.1 ifigur 1. Lysdiodstaven 2 är vidare ansluten till en andra kontaktledning, i detta fall en 0-ledning, via den högra kontaktsockeln 1.2. En . elektrisk ledning, till vilken ett antal lysdioder 2.2 är anslutna, förbinder lysdiodstavens 2 båda ändar och därmed de i dessa ändar befintliga kontaktorganen. Drivenheten 2.1 visas schematiskt i figur 2.The LED rod 2 is arranged between two contact sockets 1.1, 1.2 and comprises an electric drive unit 2.1, which is connected to a first contact line, in this case a phase line from a reactor 3, via the left contact socket 1.1 in Figure 1. The LED rod 2 is further connected to a second contact wire, in this case a 0-wire, via the right contact socket 1.2. One . electrical cable, to which a number of LEDs 2.2 are connected, connects the two ends of the LED rod 2 and thus the contact means which are insensitive at these ends. The drive unit 2.1 is shown schematically in Figure 2.

En konventionell belysningsarmatur 1 för lysrör är normalt försedd med en glimtändare, som är ansluten till ett av två kontaktorgan i form av kontaktstift i var sin ände av lysröret, men som, då detta ersätts av en lysdiodstav 2, är avlägsnad från belysningsarmaturen 1. De andra två kontaktstiften i var ände av lysröret är avsedda att anslutas till fasledningen från reaktorn 3 respektive till 0-ledningen. Lysdiodstaven 2 enligt exemplet uppvisar, liksom lysröret, två cylinderforrniga kontaktstift 2.3 anordnade i vardera änden med syfte att medge montering av lysdiodstaven 2 i en belysningsarmatur 1, som är avsedd för konventionella lysrör. Lys- diodstavens 2 kontaktstift medger anslutning till fasledningen och till 0- ledningen oavsett hur lysdiodstaven 2 förs in i kontaktsocklarna 1.1, 1.2.A conventional fluorescent lighting fixture 1 is normally provided with a spark plug, which is connected to one of two contact means in the form of contact pins at each end of the fluorescent lamp, but which, when replaced by an LED rod 2, is removed from the lighting fixture 1. the other two contact pins at each end of the fluorescent lamp are intended to be connected to the phase line from the reactor 3 and to the 0 line, respectively. The LED rod 2 according to the example has, like the fluorescent lamp, two cylindrical contact pins 2.3 arranged at each end for the purpose of allowing mounting of the LED rod 2 in a lighting fixture 1, which is intended for conventional fluorescent lamps. The contact pin of the LED rod 2 allows connection to the phase line and to the 0 line, regardless of how the LED rod 2 is inserted into the contact sockets 1.1, 1.2.

Om lysdiodstaven 2 av misstag skulle föras in endast i den fasanslutna kontaktsockeln 1.1, såsom visas med streckade linjer i figur 1, skulle åtminstone ett av kontaktstiften 2.3 iden fria änden bli strömförande och kunna vålla personskada. För att förhindra detta innefattar drivenheten 2.1 en strömbrytare 4, som uppvisar två tryckorgan 4.1 anordnade på var sida om kontaktstiften 2.3. Tryckorganen 4.1 uppbärs av en brytarkropp 4.2, som förskjuts maximalt in i lysdiodstaven 2 när dennas ändar samtidigt förs 10 15 531 535 in i kontaktsocklarna 1.1, 1.2 och sluter den ledning, som står i förbindelse med Iysdioderna 2.2. En styrtapp 4.3, anordnad på vardera sidan av brytar- kroppen 4.2 löper linjärt in i ett styrspår 4.4 i drivenheten 2.1. Om lysdiodstaven 2 skulle föras in snett i kontaktsockeln 1.1, såsom nämnts ovan, påverkas strömbrytaren 4 endast av ett av tryckorganen 4.1, varvid styrtapparna 4.3 trycks in snett i drivenheten 2.1 och stoppas av att de kommer i kontakt med endera av två stoppklackar 4.5, som är anordnade på var sida om styrspåret 4.4 på respektive sida av strömbrytaren 4.If the LED rod 2 were accidentally inserted only into the phase-connected contact socket 1.1, as shown in broken lines in Figure 1, at least one of the contact pins 2.3 at the free end would become live and could cause personal injury. To prevent this, the drive unit 2.1 comprises a switch 4, which has two pressure means 4.1 arranged on each side of the contact pins 2.3. The pressure means 4.1 are supported by a switch body 4.2, which is displaced maximally into the LED rod 2 when its ends are simultaneously inserted into the contact sockets 1.1, 1.2 and close the line which is connected to the LEDs 2.2. A guide pin 4.3, arranged on each side of the switch body 4.2 runs linearly into a guide groove 4.4 in the drive unit 2.1. If the LED rod 2 were to be inserted obliquely into the socket 1.1, as mentioned above, the switch 4 is only actuated by one of the pressure means 4.1, the guide pins 4.3 being pushed obliquely into the drive unit 2.1 and stopped by coming into contact with either of two stop lugs 4.5, are arranged on each side of the guide groove 4.4 on each side of the switch 4.

Strömbrytaren 4 kan därmed inte sluta ledningen till Iysdioderna 2.2 och därmed inte leda ström till kontaktstiflen 2.3 iden för beröring .åtkomliga . änden av lysdiodstaven 2. l ett alternativt utförande kan lampans 2 kontaktorgan. vid respektive ände av lysdiodstaven 2 utgöras av ett skivformigt organ, som skjuter ut lika långt från lampans 2 ände, som de ovan nämnda kontaktstlften 2.3, och uppvisar en tjocklek, som är lika med kontaktstiftens 2.3 diameter samt har en bredd, som motsvarar avståndet mellan kontaktstiftens 2.3 yttersidor.The switch 4 can thus not connect the line to the LEDs 2.2 and thus not lead current to the contact pins 2.3 in the contact area. the end of the LED rod 2. In an alternative embodiment, the contact means of the lamp 2 can. at each end of the LED rod 2 consists of a disc-shaped member, which projects as far from the end of the lamp 2 as the above-mentioned contact pin 2.3, and has a thickness equal to the diameter of the contact pin 2.3 and has a width corresponding to the distance between the outer surfaces of the contact pins 2.3.

Uppfinningen är inte begränsad till de här visade utföringsformerna utan kan varieras inom ramen för efterföljande patentkrav.The invention is not limited to the embodiments shown here but can be varied within the scope of the appended claims.
