LED LIGHTING PACKAGE

LED LIGHTING PACKAGE

The invention describes an LED lighting package (1) comprising a first LED string (S1) comprising a plurality of series-connected light-emitting diodes (Dred), and a first linear regulator (LR1) arranged to determine the current through the first LED string (S1); at least one further LED string (S2,...

Beschreibung
Zusammenfassung:The invention describes an LED lighting package (1) comprising a first LED string (S1) comprising a plurality of series-connected light-emitting diodes (Dred), and a first linear regulator (LR1) arranged to determine the current through the first LED string (S1); at least one further LED string (S2, S3, S4) comprising a plurality of series-connected light-emitting diodes (Dx, Dy, Dz) of a different colour, and a further linear regulator (LR2, LR3, LR4) arranged to determine the current through that LED string (S2, S3, S4); wherein the different coloured LED strings (S1, S2, S3, S4) are connected in parallel; a common voltage supply (Vin) for the LED strings (S1, S2, S3, S4); and wherein the number of light-emitting diodes (Dred) in the first LED string (S1) exceeds the number of light-emitting diodes (Dx, Dy, Dz) in each further LED string (S2, S3, S4), and the number of light-emitting diodes (Dred, Dx, Dy, Dz) in each LED string (S1, S2, S3, S4) is chosen such that the total forward voltage of a further LED string (S2, S3, S4) is essentially the same as the total forward voltage of the first LED string (S1).
