Abstract

LED-ohjain (10) käsittää tehoasteen (100), joka tuottaa käyttövirran (lout) LED-valonlähteen (12) ohjaamiseen laajalla lähtöjännitealueella (Vout), joka sisältää ainakin yhden matalan kuorman jännitealueen ja ainakin yhden korkean kuorman jännitealueen. Jännitteen tunnistava piiri (VF) on järjestetty tunnistamaan LED-valonlähteen yli vaikuttava kuormajännite (Vf). Ohjain (110) on konfiguroitu ohjaamaan tehoasteen (100) toimintaa eri kuormanohjausasetuksilla sen mukaan, onko havaittu kuormajännite mainitulla ainakin yhdellä matalan kuorman jännitealueella vai mainitulla ainakin yhdellä korkean kuorman jännitealueella, kun LED-ohjain (10) kytketään ensimmäisen kerran LED-valonlähteeseen (12).
