Claims (9)

1. Förkopplingsanordning för en urladdningslampa (L), vilken i serie med en serieresonanskrets (L7, C21) 5 bildar lastkrets av en växelriktare, vars omkopplare (V7 , V8) avhängigt av spänningar hos sekundärlindningar (L83, L84) styrs av en transformator (T8) , vilken med sin primär-lindning (L81) likasä ligger i lastkretsen, kanne-t e c k n a d därav, att transformatorn (T8) har en yt- 10 terligare sekundärlindning (L82), som ligger parallellt med en transistor (V10) av en bistabil koppiingsanordning (K), och att denna koppiingsanordning (K) via ett RC-organ styrs avhängigt av Ström i lastkretsen av växelriktaren, varvid den vid ett gränsvärde av sin ingängsspänning intar 15 ett urkopplingstillständ, i vilket transistorn (V10) är i ledande tillständ.
2. Förkopplingsanordning enligt patentkravet 1, kännetecknad därav, att transformatorns (T8) ytterligare lindning (L82) via en diod (D41) matar RC-or- 20 ganet i ingängskretsen av den bistabila kopplingsanord-ningen (K).
3. Förkopplingsanordning enligt patentkravet 2, kännetecknad därav, att RC-organet (C11 , R1 4 , C10) i ingängskretsen av den bistabila kopplingsanord- 25 ningen (K) ligger parallellt med transistorn (V10) av den bistabila kopplingsanordningen (K).
4. Förkopplingsanordning enligt nägot av patentkra-ven 1-3, med en likströmsregulator (L4, V6, D27, C18, X) mellan växelriktaren och en likspänningskälla (G1), 30 kännetecknad därav, att likströmsregulatorn är i urkopplingstillständ dä transistorn (VI0) av den bistabila kopplingsanordningen (K) är i ledande tillständ.
5. Förkopplingsanordning enligt patentkravet 4, kännetecknad därav, att en enda likströmsregu- 35 lator anordnats för matande av tvä växelriktare, vilken urkopplas via en OCH-grind (R60, D61, D62), dä de bistabila kopplingsanordningarna (K) av bäda växelriktarna (W) befin-
