Abstract

Oppfinnelsen vedrører en krets for å drive et lyssignal, nærmere bestemt et LEDsignal, omfattende i det minste en lysemitterende diode (L), til hvilken en motstand (RI) er seriekoblet og en styring er parallellkoblet. For å forbedre lysstyrken til lysemitteringsdioden (L) når vekselstrøm er levert, er nevnte lysemitterende diode koblet i en Graetzlikeretterbro og styringen har en seriekobling med en motstand (R2) og en bryter (S) til hvilken en spenningsdeler (R3/R4) som treffer mot nevnte bryter (S) er parallellkoblet.
