摘要:
A light emitting diode, LED, filament (100, 310), comprising a plurality of light emitting diodes (110, 150, 155, 250, 255), LEDs, wherein the LED filament comprises a center axis, A, and elongates in a meandering shape in a first plane, P, wherein a first portion (120, 220) of the LED filament, which elongates along the center axis, A, comprises an array of the plurality of LEDs and an encapsulant (210) at least partially enclosing the array of the plurality of LEDs, and a second portion (140, 240) of the LED filament, which elongates along the center axis, A, comprises a distribution of LEDs (150, 155) of the plurality of LEDs, and wherein the first portion and the second portion of the LED filament are arranged on opposite sides with respect to the first plane, P.
