DK 177611 B1 LED-rør med sikkerhedskredsløb samt anvendelseDK 177611 B1 LED tube with safety circuit and use
Opfindelsen angår et LED-rør til lysafgivelse med elektriske terminaler a1, a2 i en rørende samt elektriske terminaler b1, b2 i den modstående 5 rørende, hvor LED-røret mellem a1, a2 og b1, b2 terminalerne er forsynet med elektroniske kredsløb såsom i form af et antal fortrinsvis to diodebroer samt et LED modul, som omfatter et antal lysdioder, og hvor LED-røret kan monteres i et lysstofrørsarmatur med en Starter samt en Ballast, hvor LED-røret er forsynet med et sikkerhedskredsløb, som kun åbner for elektrisk 10 strøm mellem de elektriske terminaler a1, a2 og b1, b2, når LED-røret er korrekt monteret i et lysstofrørsarmatur.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a LED tube for light emitting with electrical terminals a1, a2 in a tube and electrical terminals b1, b2 in the opposite tube, wherein the LED tube between a1, a2 and b1, b2 terminals is provided with electronic circuits such as in form a plurality of preferably two diode bridges as well as an LED module comprising a plurality of LEDs, wherein the LED tube can be mounted in a fluorescent lamp fixture with a Starter and a Ballast, wherein the LED tube is provided with a safety circuit which opens only for electrical 10 current between the electrical terminals a1, a2 and b1, b2 when the LED tube is properly mounted in a fluorescent lamp fixture.
Desuden angår opfindelsen anvendelse af LED-rør.In addition, the invention relates to the use of LED tubes.
15 Gas-fyldte lysstofrør er konstrueret således, at de fungerer ligegyldigt hvordan de vendes i armaturet. Man kan endog indsætte den ene ende af røret i armaturet, med strømmen tændt, uden at der kommer spænding på rørets anden ende, idet rørets gas ikke er ledende, før røret er korrekt monteret og startet.15 Gas-filled fluorescent lamps are designed so that they function no matter how they are turned in the luminaire. You can even insert one end of the pipe into the luminaire, with the power turned on, without any tension on the other end of the pipe, since the gas of the pipe is not conductive until the pipe is properly installed and started.

For at reducere energiforbruget samt for at højne lyskvaliteten er der fremstillet såkaldte LED-rør, som kan placeres i lysstofrørsarmaturer og dermed substituere lysstofrørene.In order to reduce energy consumption and to improve the quality of light, so-called LED tubes have been manufactured, which can be placed in fluorescent lamp fixtures and thus substitute the fluorescent lamps.
25 LED-rør adskiller sig fra lysstofrør ved, at de ikke indeholder en gas, men i stedet et antal LED’s (Light Emitting Diode) og et elektrisk kredsløb, der er forbundet til terminalerne i begge ender af røret for at sikre kompatibilitet med eksisterende lysstofrørs armaturer.25 LEDs differ from fluorescent lamps in that they do not contain a gas, but instead a number of LEDs (Light Emitting Diode) and an electrical circuit connected to the terminals at both ends of the tube to ensure compatibility with existing fluorescent lamps. fixtures.
30 Det har imidlertid vist sig, at der er nogle problemer ved de kendte LED-rør.30 However, it has been found that there are some problems with the known LED tubes.
2 DK 177611 B12 DK 177611 B1
Eftersom LED-rørs kredsløb er forbundet i begge ender af røret for at sikre kompatibilitet med eksisterende armaturer, så kan man ved fejlmontage risikere, at der løber en strøm fra den ene monterede ende af rørets terminaler til den anden ende af røret, såfremt strømmen til armaturet er 5 tændt.Since LED tube circuits are connected at both ends of the tube to ensure compatibility with existing luminaires, there may be a risk of error flowing from one mounted end of the tube terminals to the other end of the tube if the current to the the fixture is 5 lit.
Såfremt en installatør eller anden operatør berører terminalerne på den tilgængelige, anden ende af LED-røret og samtidig berører jord på armaturet eller andet steds, er der risiko for elektrisk stød.If an installer or other operator touches the terminals on the accessible, other end of the LED tube and at the same time touches ground on the luminaire or elsewhere, there is a risk of electric shock.

Fra EP 2381159 A2 (TEKNOWARE OY [Fl]), Oct. 26, 2011 kendes et LED-rør, hvor LED-røret kan monteres i et lysstofarmatur med en Starter og en Ballast og hvor LED-røret er forsynet med et sikkerhedskredsløb, som kun åbner for elektrisk strøm mellem de elektriske terminaler, når LED-røret er 15 korrekt monteret i lysstofrørsarmaturet.From EP 2381159 A2 (TEKNOWARE OY [Fl]), Oct. 26, 2011, an LED tube is known in which the LED tube can be mounted in a fluorescent luminaire with a Starter and a Ballast and where the LED tube is provided with a safety circuit which opens only electrical current between the electrical terminals when the LED tube is correctly mounted in the fluorescent lamp fixture.
Det er imidlertid en ulempe ved teknikken beskrevet i EP 2381159 A2 at sikkerhedskredsløbet anvender relativt bekostelige komponenter.However, it is a disadvantage of the technique described in EP 2381159 A2 that the safety circuit uses relatively expensive components.
20 Det er derfor et formål med opfindelsen, at anvise et LED-rør uden ovennævnte ulemper.It is therefore an object of the invention to provide an LED tube without the above disadvantages.
Opfindelsens formål tilgodeses ved et LED-rør af den i indledningen til krav 1 angivne type, som er karakteristisk ved, at sikkerhedskredsløbet omfatter 25 en diodebro, der drives af a1, a2 terminalerne og som styrer en kontakt, der er placeret i serie med LED modulet.The object of the invention is met by an LED tube of the type set forth in the preamble of claim 1, characterized in that the safety circuit comprises a diode bridge operated by the a1, a2 terminals and which controls a switch located in series with the LED module.
På denne måde bliver det således muligt at montere og demontere LED-rør i eksisterende lysstofrørsarmaturer uden risiko for at montøren udsættes for 30 elektriske stød, med anvendelse af et sikkerhedskredsløb som fremstilles af billige standardkomponenter.In this way, it becomes possible to install and disassemble LED tubes in existing fluorescent lamp fixtures without the risk of exposing the installer to 30 electric shocks, using a safety circuit manufactured from cheap standard components.
3 DK 177611 B1 Øvrige hensigtsmæssige udførelsesformer for fremgangsmåden er angivet i kravene 2 og 3.Other suitable embodiments of the method are set out in claims 2 and 3.
5 Som nævnt angår opfindelsen også anvendelsen af LED-rør til substitution af lysstof rør.As mentioned, the invention also relates to the use of LED tubes for the substitution of fluorescent tubes.
Herved bliver det muligt, at substituere lysstofrør med LED-rør med deraf reduceret energiforbrug og øget lyskvalitet uden at montøren udsættes for 10 risiko for at få helbredstruende elektriske stød.This makes it possible to substitute fluorescent lamps with LED tubes with reduced energy consumption and increased light quality without exposing the installer to 10 risk of having health-threatening electric shocks.

20 På fig. 1 er med 1 betegnet et LED-rør som internt er traditionelt opbygget som vist i principskitsen fig. 1.1.20 In FIG. 1 is indicated by 1 as an LED tube which is internally traditionally constructed as shown in the principle sketch fig. 1.1.
LED-røret 1 er placeret i et lysstofrørsarmatur, der omfatter en såkaldt 25 starter, som i den i fig. 1 viste placering af LED-røret 1 er placeret mellem LED-rørs 1 terminalerne a1 og b1.The LED tube 1 is located in a fluorescent tube fitting comprising a so-called starter, as in the embodiment shown in FIG. 1 of the LED tube 1 is located between the terminals a1 and b1 of the LED tube 1.
Lysstofrørsarmaturet er desuden forsynet med en såkaldt ballast, som er placeret mellem lysnettets L terminal og LED-rørs 1 terminalen a2.The fluorescent lamp fixture is furthermore provided with a so-called ballast, which is located between the mains L terminal and the LED tube 1 terminal a2.
LED-rørets 1 terminal b2 er i den i fig. 1 viste placering af LED-røret 1 30 5 DK 177611 B1 forbundet til lysnettets N (Neutral) terminal.The terminal b2 of the LED tube 1 is in the embodiment shown in FIG. 1 of the LED tube 1 30 5 DK 177611 B1 connected to the N (Neutral) terminal of the mains.
Lysstofarmaturet 1 kan som anført i fig. 1 være skærmet ved forbindelse til jord (PE).The luminaire luminaire 1, as shown in FIG. 1 be shielded when connected to ground (PE).

Den elektriske strøm, der løber i kredsløbet som anvist i fig. 1 ved normalt drift, er anført ved 5.The electrical current flowing in the circuit as shown in FIG. 1 in normal operation is indicated by 5.
Fig. 1.1 viser en principskitse over det elektriske kredsløb, som er 10 indesluttet i LED-røret 1 interne opbygning.FIG. 1.1 shows a principle sketch of the electrical circuit, which is 10 enclosed in the LED tube 1 internal structure.
Som det vil fremgå af fig. 1.1, er LED-rørets 1 endeterminaler a1, a2 forbundet til en diodebro 6, hvis udgangsterminaler er forbundet til et LED modul 7, som omfatter de lysdioder, der skaber lyset, når LED-røret 1 15 aktiveres.As will be seen from FIG. 1.1, the end terminals a1, a2 of the LED tube 1 are connected to a diode bridge 6, the output terminals of which are connected to an LED module 7, which comprises the LEDs which create the light when the LED tube 1 is activated.
Desuden er diodebroens 6 udgangsterminaler forbundet til en diodebro 8, hvis to øvrige terminaler er forbundet til de to LED-rørs 1 terminaler b1, b2.In addition, the output terminals of the diode bridge 6 are connected to a diode bridge 8, the other two terminals of which are connected to the terminals b1, b2 of the two LED tubes 1.
20 I fig. 1.1 er den elektriske strøm gennem LED-røret 1 anført ved 5.In FIG. 1.1, the electrical current through the LED tube 1 is indicated at 5.
Fig. 2 viser et LED-rør 1, som kun er monteret i den ene ende ved terminalerne a1, a2, således et terminalerne b1, b2 er frie og derfor kan berøres af en bruger eller montør.FIG. 2 shows an LED tube 1 mounted only at one end at terminals a1, a2, thus one terminals b1, b2 are free and can therefore be touched by a user or installer.

Situationen som skildres i fig. 2 kan således forekomme ved montering eller demontering af et LED-rør 1 til eller fra et lysstofrørsarmatur.The situation depicted in FIG. 2 can thus occur when mounting or disassembling an LED tube 1 to or from a fluorescent lamp fixture.
Såfremt lysstofrørsarmaturet i den i fig. 2 viste situation er koblet til 30 lysnettet, vil der med et traditionel elektrisk kredsløb som anført ved fig. 1.1 af LED-røret 1 kunne løbe en elektrisk strøm 9 gennem LED-røret 1.If the fluorescent lamp fixture in the one shown in FIG. 2 is connected to the mains, with a conventional electrical circuit as indicated in FIG. 1.1 of the LED tube 1 could run an electric current 9 through the LED tube 1.

Strømmen 9 vil således kunne løbe gennem en montør, der kommer i berøring med endeterminalerne b1, b2, såfremt montøren har kontakt til eksempelvis jordpotentialet (PE).Thus, the current 9 can pass through an installer which comes into contact with the end terminals b1, b2 if the installer has contact, for example, with the earth potential (PE).

Et sådant elektrisk stød kan i værste fald være livstruende.Such an electric shock can be life-threatening at worst.
I fig. 3 er vist hvorledes det traditionelle LED-rørs 1 elektriske kredsløb i henhold til opfindelsen kan modificeres med et sikkerhedskredsløb 10, der 10 fjerner risikoen for elektriske stød for en bruger eller montør, som ovenfor beskrevet.In FIG. 3 is shown how the conventional LED tube 1 electrical circuit according to the invention can be modified with a safety circuit 10 which removes the risk of electric shock to a user or installer, as described above.
Sikkerhedskredsløbet 10 omfatter en afbryder eller kontakt 12, som er indsat i serie med LED modulet 7, hvor kontakten 12 er styret af et kredsløb 15 11, der er koblet til endeterminalerne a1, a2 således at kontakten 12 kun sluttes såfremt der er driftsspænding på tværs af terminalerne a1, a2.The safety circuit 10 comprises a circuit breaker or switch 12 which is inserted in series with the LED module 7, wherein the switch 12 is controlled by a circuit 15 11 connected to the end terminals a1, a2 such that the switch 12 is closed only if there is a transverse operating voltage. of terminals a1, a2.
Hermed sikres, at der kun kan løbe strøm gennem LED modulet 7, når LED-røret 1 er korrekt placeret i et lysstofrørsarmatur således at både 20 endeterminalerne a1, a2 og b1, b2 er isat lysstof rørsarmaturet.This ensures that current can only flow through the LED module 7 when the LED tube 1 is properly placed in a fluorescent lamp fixture so that both the end terminals a1, a2 and b1, b2 are inserted into the fluorescent tube fixture.
I fig. 3 er vist en foretrukket udførelsesform af kredsløbet 11 i form af en diodebro.In FIG. 3 is a preferred embodiment of the circuit 11 in the form of a diode bridge.
25 Fig. 4 viser hvorledes den elektriske strøm 13 løber gennem lysstof rørsarmaturet og LED-røret 1, når LED-røret 1 er modificeret med et sikkerhedskredsløb 10.FIG. 4 shows how the electrical current 13 runs through the fluorescent tube fixture and the LED tube 1 when the LED tube 1 is modified with a safety circuit 10.
I fig. 4.1 er vist hvorledes den elektriske strøm 13 løber i det modificerede 30 interne LED-rørs 1 kredsløb, som er forsynet med et sikkerhedskredsløb 10 omfattende en kontakt 12 og en diodebro 11, når LED-røret 1 er korrekt DK 177611 B1 7 placeret i et lysstofrørsarmatur som vist i fig. 4.In FIG. 4.1 is shown how the electrical current 13 runs in the modified 30 internal LED tube 1 circuit, which is provided with a safety circuit 10 comprising a switch 12 and a diode bridge 11, when the LED tube 1 is correctly placed in a fluorescent lamp fixture as shown in FIG. 4th
Fig. 5 viser et LED-rør 1 modificeret med et sikkerhedskredsløb 10, hvor LED-røret 1 kun har det ene sæt endeterminaler a1, a2 placeret i et 5 lysstofrørsarmatur, hvor den elektriske strøm der kan løbe gennem LED-røret 1 er anført ved 14.FIG. 5 shows an LED tube 1 modified with a safety circuit 10, wherein the LED tube 1 has only one set of end terminals a1, a2 located in a fluorescent lamp fixture, the electrical current which can flow through the LED tube 1 is indicated by 14.
Fig. 5,1 viser hvorledes den elektriske strøm 14 vil løbe i LED-røret 1, der er forsynet med et sikkerhedskredsløb 10 som omfatter en kontakt 12 og en 10 diodebro 11, og hvor LED-røret 1 er placeret med kun et sæt endeterminaler a1, a2 placeret i et lysstofrørsarmatur som anført ved fig. 5.FIG. 5.1 shows how the electrical current 14 will run in the LED tube 1 provided with a safety circuit 10 comprising a switch 12 and a 10 diode bridge 11, and wherein the LED tube 1 is located with only a set of end terminals a1, a2 located in a fluorescent lamp fixture as indicated in FIG. 5th
Da der i en konfiguration som anført ved fig. 5 ikke er driftsspænding over terminalerne a1, a2 forbliver kontakten 12 afbrudt, og den elektriske strøm 15 14 kan derfor ikke løbe gennem LED modulet 7 og kan derfor heller ikke passere endeterminalerne b1, b2.Since in a configuration as indicated by FIG. 5, there is no operating voltage across terminals a1, a2, the contact 12 remains disconnected, and therefore the electrical current 15 14 cannot pass through the LED module 7 and therefore cannot pass the end terminals b1, b2.
Med et LED-rør 1, som er modificeret med et sikkerhedskredsløb 10, kan en bruger eller montør således ikke risikere at få stød ved berøring af de fri 20 endeterminaler b1, b2 hvor kun et sæt endeterminaler a1, a2 er placeret i et lysstofrørsarmatur.Thus, with an LED tube 1 modified with a safety circuit 10, a user or installer cannot risk being hit by touching the free 20 end terminals b1, b2 where only one set of end terminals a1, a2 is located in a fluorescent lamp fixture.
Et LED-rør, som er modificeret med et sikkerhedskredsløb 10 i henhold til opfindelsen, vil virke uafhængigt af, hvordan LED-røret 1 vendes i forhold til 25 et lysstofrørsarmatur, hvilket illustreres i fig. 6.An LED tube modified with a safety circuit 10 according to the invention will operate independently of how the LED tube 1 is turned relative to a fluorescent lamp fixture, as illustrated in FIG. 6th
I Fig. 6 er således vist en situation med et LED-rør 1 modificeret med et sikkerhedskredsløb 10 som er vendt 180 grader i forhold til den i fig. 5 viste situation.In FIG. 6, there is thus shown a situation with an LED tube 1 modified with a safety circuit 10 which is turned 180 degrees with respect to the one shown in FIG. 5.
Fig. 6.1 viser hvorledes den elektriske strøm 15 vil løbe i LED-rørets 1 30 DK 177611 B1 8 interne kredsløb.FIG. 6.1 shows how the electrical current 15 will run in the internal circuit of the LED tube 1 30 DK 177611 B1 8.
Da der ved situationen afbildet i fig 5 og fig. 5.1 ikke er driftsspænding mellem terminalerne a1 og a2, vil kontakten 12 forblive afbrudt og der kan 5 derfor ikke løbe elektrisk strøm 15 på tværs af LED-røret 1.Since in the situation depicted in FIG. 5 and FIG. 5.1 is not operating voltage between terminals a1 and a2, switch 12 will remain disconnected and therefore 5 cannot run electrical current 15 across LED tube 1.
For at undgå at der ligger en permanent strøm over Starteren efter opstart, kan sikkerhedskredsløbet 10 modificeres som anført ved fig. 7. Der indskydes en kontakt 17 i serie med den allerede eksisterende kontakt 12 10 for at frakoble strømmen over Starteren. Der kan så tilføjes en kontakt 16, som placeres parallelt over kontakten 12 for at sikre, at LED modulet 7 holdes tændt, når Starteren frakobles via 17. Kontakterne 16 og 17 er styret af LED modulet 7, således at disse er aktive, når LED modulet 7 er tændt.In order to avoid a permanent current over the Starter after start-up, the safety circuit 10 can be modified as indicated in FIG. 7. A switch 17 is inserted in series with the already existing switch 12 10 to disconnect the current over the starter. A switch 16 may then be added which is placed parallel to the switch 12 to ensure that the LED module 7 is kept on when the starter is switched off via 17. The contacts 16 and 17 are controlled by the LED module 7 so that they are active when the LED module 7 is on.
15 Det skal pointeres, at et LED-rør 1 modificeret med et sikkerhedskredsløb 10 vil fungere i eksisterende lysstof rørsarmaturer uden nogen form for ændringer i disse.15 It should be pointed out that an LED tube 1 modified with a safety circuit 10 will function in existing fluorescent tube fittings without any changes in them.
LED-rør 1 modificeret med et sikkerhedskredsløb 10 kan derfor simpelt og 20 sikkert anvendes til at substituere alle eksisterende lysstofrør.Therefore, LED tubes 1 modified with a safety circuit 10 can simply and safely be used to substitute all existing fluorescent lamps.
