1. A LED filament including a linear array of LEDs arranged on a carrier substrate, wherein:
the linear array is divided into two separate longitudinal sections, a first longitudinal section including only LEDs configured to emit white light with a color temperature, and a second longitudinal section including only color controllable LEDs configured to emit color controllable light, said color controllable LEDs comprise LED groups each including a red LED, a green LED and a blue LED, within each group the LEDs are arranged non-linearly, e.g. in a triangle fashion, and
wherein LEDs in each groups are separated by a first, intra-group distance, and wherein groups are separated by a second, inter-group distance, wherein said inter-group distance is greater than said intra-group distance; and
wherein the two longitudinal sections are separated by a distance to enable a bend between the two longitudinal sections and allow for two separate encapsulants over respective longitudinal sections.
