LED filament and LED filament lamp

A light emitting diode filament for providing LED filament light, comprising:

• a first linear array of LEDs arranged on a first surface of a carrier including only first LEDs configured to emit first white light,
• a second linear array of LEDs arranged on a second surface of the carrier, opposite to said first surface, including only second LEDs configured to emit color controllable light,
• wherein the LED filament light comprises the first white light and the color controllable light,
• wherein the first LEDs comprise UV LEDs emitting UV light and/or blue LEDs emitting blue light, the UV LEDs and/or blue LEDs being covered by a first encapsulant comprising a luminescent material configured to at least partly convert the UV light and/or the blue light into converted light, wherein the white light comprises (i) the converted light and optionally (ii) the non-converted UV light and/or the non-converted blue light, wherein the first LEDs have a first pitch,
• wherein the second linear array of LEDs comprises a plurality of M groups, each group comprising a red LED, a green LED and a blue LED, wherein the second LEDs and have a second pitch, and
• wherein the first pitch is different from the second pitch.
