Beschreibung
Zusammenfassung:	The present invention relates to an LED filament (10), comprising: a first LED filament portion (12a) comprising a plurality of first LEDs (14a) adapted to emit first LED filament light: a second LED filament portion (12b) parallel to the first LED filament portion (12a) and comprising a plurality of second LEDs (14b) adapted to emit second LED filament light: and at least one light-blocking wall (26) arranged between the first and second LED filament portions to reduce or prevent optical cross-talk between the first and second LEDs.
