Description

Hjelpeanordning til regulering av lysheten av lavspennings- lysstofflamper Auxiliary device for regulating the brightness of low-voltage fluorescent lamps

Oppfinnelsen angår en hjelpeanordning til å regulere lysheten av lavspennings-lysstofflamper med forkoblingsdrossel ved hjelp av innsnittsstyrende lysdempere. The invention relates to an auxiliary device for regulating the brightness of low-voltage fluorescent lamps with a ballast by means of notch-controlling dimmers.

De enkleste dempere, deriblant de som oftest forekommerThe simplest dampers, including those that occur most often

i handelen, er innsnittkontrollerende, altså fasestyrende, dempere som også ofte betegnes som spenningskontrollerende dempere, hvor lysheten av lampene således reguleres ved hjelp av en varierende spenning. Ved lavspennings-lysstofflamper står der bare et reguleringsområde på knapt. 10% til rådighet for formålet, siden slike lamper slukner ved en spenning under 200 Volt. Der forekommer derfor på markedet også spesial-dempere som representerer en stor teknisk og økonomisk på-kostning. in the trade, are notch-controlling, i.e. phase-controlling, dimmers which are also often referred to as voltage-controlling dimmers, where the brightness of the lamps is thus regulated by means of a varying voltage. In the case of low-voltage fluorescent lamps, there is only a regulation area on the button. 10% available for the purpose, since such lamps go out at a voltage below 200 Volts. There are therefore also special dampers on the market that represent a large technical and financial cost.

Til grunn for oppfinnelsen ligger den oppgave å utvikle en hjelpeanordning til å regulere lysheten av lavspennings-lysstof f lamper ved hjelp av fasestyrende dempere som forekommer vanlig i handelen. The invention is based on the task of developing an auxiliary device for regulating the brightness of low-voltage fluorescent lamps by means of phase-controlling dampers which are commonly found in the trade.

Ifølge oppfinnelsen blir den angitte oppgave løst ved hjelp av en elektronisk ventil med en nettsidig tilslutning for forkoblingsdrosselen og en nettsidig tilslutning for demperen ført til den elektroniske ventils styreelektrode, According to the invention, the specified task is solved by means of an electronic valve with a net-side connection for the ballast throttle and a net-side connection for the damper led to the electronic valve's control electrode,

en lampesidig tilslutning samt ytterligere, av den elektroniske ventil uavhengige, nettsidige tilslutninger for midtpunktlederen resp. ytterlederen samt en ytterligere lampesidig tilslutning for disse. Ved bruk av en slik anordning blir demperen ikke belastet induktivt av forkoblingsdrosselen. Hjelpeanordninen kan også ved eksisterende lamper innkobles mellom de lampesidige tilslutninger og de nettsidige tilslutninger for forkoblingsdrosselen og for demperen samt for midtledertilslutningen. a lamp-side connection as well as further, net-side connections independent of the electronic valve for the mid-point conductor or the outer conductor as well as a further lamp-side connection for these. When using such a device, the damper is not loaded inductively by the ballast choke. The auxiliary device can also be connected to existing lamps between the lamp-side connections and the mains-side connections for the ballast choke and for the damper as well as for the center conductor connection.

Den elektroniske ventil kan være en triac med styresidig forkoblet kondensator. The electronic valve can be a triac with a pre-connected capacitor on the control side.

Hjelpeanordningen er særlig velskikket for lavspennings-lysstof f lamper med induktiv hurtigstartanordning av kjent art. I den forbindelse kan hjelpeanordningen også omfatte innretninger for en induktiv hurtigstartanordning, og der er da mellom den nettsidige tilslutning for midtpunktlederen og den lampesidige tilslutning for den elektroniske styreventil innkoblet en høyspenningsspole som er koblet med den induktive hurtigstartanordnings jernkjerne. En slik hjelpeanordning gjør det mulig å regulere lysheten av lavspennings-lysstofflamper særlig langt ned. Høyspenningsspolen for en avgangs-sidig spenning på ca. 600-1500 Volt sørger for en grunn-ionisasjon på det laveste lysstadium. Videre sørger de to sekundærviklinger hos den induktivt arbeidende hurtigstartanordning for å varme opp lampeelektrodene på vanlig måte. The auxiliary device is particularly suitable for low-voltage fluorescent lamps with an inductive quick-start device of a known type. In that connection, the auxiliary device can also include devices for an inductive quick-start device, and there a high-voltage coil connected to the inductive quick-start device's iron core is connected between the mains-side connection for the mid-point conductor and the lamp-side connection for the electronic control valve. Such an auxiliary device makes it possible to regulate the brightness of low-voltage fluorescent lamps particularly far down. The high-voltage coil for an output-side voltage of approx. 600-1500 Volts ensures basic ionization at the lowest light stage. Furthermore, the two secondary windings of the inductively working quick-start device ensure that the lamp electrodes are heated in the usual way.

Ved anvendelse av en induktiv hurtigstartanordning iWhen using an inductive quick start device i

en lukket kapsel kan man innkoble primærviklingen mellom den nettsidige tilslutning for midtpunktlederen og den nettsidige tilslutning for ytterlederen og føre forbindelser fra en sekundærvikling, hvis ene pol er forbundet med primærviklingens midtpunkttilslutning, til lampesidige eksterne tilslutninger. Fra den annen sekundærvikling kan man føre en forbindelse ut til en ytterligere lampesidig tilslutning og en ytterligere forbindelse til den lampesidige tilslutning for den elektroniske styreventil. Herved oppnår man en kompakt oppbygget hjelpeanordning med få og oversiktlige eksterne tilslutninger. a closed capsule, the primary winding can be connected between the mains-side connection for the center conductor and the mains-side connection for the outer conductor and connections from a secondary winding, one pole of which is connected to the primary winding's mid-point connection, to external connections on the lamp side. From the second secondary winding, a connection can be made to a further lamp-side connection and a further connection to the lamp-side connection for the electronic control valve. This results in a compact auxiliary device with few and clear external connections.

Oppfinnelsen vil bli belyst nærmere ved et utførelses-eksempel som er anskueliggjort grovt skjematisk på tegningen. The invention will be elucidated in more detail by an embodiment example which is shown roughly schematically in the drawing.

Lavspennings-lysstofflampen 1 er på vanlig måte vedThe low-voltage fluorescent lamp 1 is normally on

hjelp av forkoblingsdrosselen 2 begrenset med hensyn til strømuttak. Ved hjelp av en innsnittkontrollerende demper 3 av en utførelse som forekommer vanlig i handelen, er det mulig å regulere lysheten av lampen. For å gjøre det mulig å anvende en slik enkel demper 3 er der innskutt en hjelpeanordning 4. Denne består i det vesentlige av en elektronisk ventil 5 med en nettsidig tilslutning 6 for forkoblingsdrosselen og en nettsidig tilslutning 8 for demperen 3 ført til styreelektroden 7 hos den elektroniske ventil 5. Ytterligere nettsidige tilslutninger 9 og 66 som er uavhengige with the help of the ballast choke 2 limited with regard to current draw. With the help of an incision-controlling damper 3 of a design that occurs commonly in the trade, it is possible to regulate the brightness of the lamp. To make it possible to use such a simple damper 3, an auxiliary device 4 has been inserted. This essentially consists of an electronic valve 5 with a net-side connection 6 for the ballast choke and a net-side connection 8 for the damper 3 led to the control electrode 7 of the electronic valve 5. Additional net-side connections 9 and 66 which are independent

av den elektroniske ventil, er anordnet for midtpunktlederen M og for tilkobling av ytterlederen LI. Midtpunktlederens potensial er ført til den lampesidige tilslutning 10. Den elektroniske ventil 5 er med sin utgang forbundet med en lampesidig tilslutning 14. of the electronic valve, is arranged for the midpoint conductor M and for connecting the outer conductor LI. The mid-point conductor's potential is led to the lamp-side connection 10. The electronic valve 5 is connected with its output to a lamp-side connection 14.

I utførelseseksempelet er den elektroniske ventil 5In the design example, the electronic valve is 5

vist som triac med en styresidig forkoblet kondensator 11. Denne kondensator 11 kan i praksis ha en kapasitet av omtrent 01,1 uF. Den differensierer styrespenningen slik at et spen-ningssprang fra den fasestyrende demper fører til tenning av triacen 5. shown as a triac with a control-side pre-connected capacitor 11. This capacitor 11 can in practice have a capacity of approximately 01.1 uF. It differentiates the control voltage so that a voltage jump from the phase-controlling damper leads to the ignition of the triac 5.

Omfatter hjelpeanordningen 4 også innretninger for en induktiv hurtigstartanordning 12 av kjent art, lar det seg dermed lett gjøre å integrere en høyspenningsspole. Mellom den nettsidige tilslutning 9 for midtpunktlederen M og den lampesidige tilslutning 14 for den elektroniske styreventil 5 innkobles fordelaktig høyspenningsspolen 13, som er koblet med . jernkjernen 15 hos den induktive hurtigstartanordning 12. Høyspenningsspolen 13 kan fordelaktig dimensjoneres slik at den ved sine klemmer avgir en spenning omtrent i et område fra 600 til 1500 Volt. If the auxiliary device 4 also includes devices for an inductive quick-start device 12 of a known type, it is thus easy to integrate a high-voltage coil. Between the mains-side connection 9 for the midpoint conductor M and the lamp-side connection 14 for the electronic control valve 5, the high-voltage coil 13 is advantageously connected, which is connected with . the iron core 15 of the inductive quick-start device 12. The high-voltage coil 13 can advantageously be dimensioned so that at its terminals it emits a voltage approximately in a range from 600 to 1500 Volts.

Den induktive hurtigstartanordning 12 er i utførelses-eksempelet fordelaktig anbragt i en felles kapsel. Mellom den nettsidige tilslutning .9 for midtpunktlederen m og den nettsidige tilslutning 66 for ytterlederen L1 er hurtigstart-anordningen 12 innkoblet med sin primærvikling 16. Fra en sekundærvikling 17 hvis ene pol er forbundet med primærviklingens midtpunkttilslutning, er der ført forbindelser til tilslutninger resp. tilkoblingsklemmer 10 og 17. Fra den annen sekundærvikling 18 er der utformet en forbindelse til en ytterligere tilslutning 19 og en ytterligere forbindelse til den lampesidige tilslutning 14 for den elektroniske styreventil 5. In the embodiment, the inductive quick start device 12 is advantageously placed in a common capsule. Between the net-side connection .9 for the midpoint conductor m and the net-side connection 66 for the outer conductor L1, the quick-start device 12 is connected with its primary winding 16. From a secondary winding 17, one pole of which is connected to the midpoint connection of the primary winding, there are connections to connections resp. connection terminals 10 and 17. From the second secondary winding 18, a connection is formed to a further connection 19 and a further connection to the lamp-side connection 14 for the electronic control valve 5.

I serie med høyspenningsspolen 13 kan der være innkoblet en strømbegrensningsmotstand 20 på ca. 3,3 Megohm. Som ytterligere starthjelp for lavspennings-lysstofflampen 1 er det mulig på vanlig måte å benytte den jordede lampekapsel, som er antydet symbolsk ved en stiplet linje 21. In series with the high-voltage coil 13, a current limiting resistor 20 of approx. 3.3 Megohms. As an additional starting aid for the low-voltage fluorescent lamp 1, it is possible to use the grounded lamp capsule in the usual way, which is indicated symbolically by a dashed line 21.

Lavspennings-lysstofflampens lastkrets dannes på nett-siden av en ytterledning L1 tilkoblet forkoblingsdrosselen 2, og midtpunktlederen som er tilkoblet ved tilslutningen 9, samtidig som potensialet på ytterlederen, betegnet L2, også tilføres demperen 3, hvorved lavspennings-lysstofflampen kan reguleres med hensyn til lyshet. The low-voltage fluorescent lamp's load circuit is formed on the mains side by an outer wire L1 connected to the ballast choke 2, and the mid-point conductor which is connected at the connection 9, at the same time that the potential on the outer conductor, designated L2, is also supplied to the dimmer 3, whereby the low-voltage fluorescent lamp can be regulated with respect to brightness .
