The LED filament lamp (100) comprises at least one LED filament (101) which has a LED filament length (L) which extends from a first end (1003) to a second end (1004). The at least one LED filament (101) provides LED filament light (101') and comprises an array (102) of a plurality of LEDs (103) and an encapsulant (104). The array (102) of a plurality of LEDs (103) provide LED light (103') and extend along the LED filament length (L). The encapsulant (104) is at least partially enclosing the plurality of LEDs (103). The encapsulant (104) comprises a light scattering material (105). In the direction from the first end (1003) to the second end (1004) at least one of (i) the thickness (TL) of the encapsulant (104), and (ii) the concentration (CL) of the light scattering material (105) in the encapsulant (104), along the LED filament length (L) increases over at least two adjacent first LEDs (106) and decreases over at least two adjacent second LEDs (107) different from the at least two adjacent first LEDs (106), and wherein the thickness (TL) and/or concentration (CL) firstly increases and secondly decreases at least along a portion of the LED filament length (L).

    Abstract: A LED filament (100) comprising an elongated substrate (110), a first region (120), a second region (130) and a third region (140) arranged between the first and second region. The first region comprises a plurality of LEDs (121) of a first LED type configured to emit light with a first CCT, arranged along at least one row on the substrate. The second region comprises a plurality of LEDs (131) of a second LED type configured to emit light with a second CCT, different from said first CCT, arranged along at least one row on the substrate. The third region (140) comprises at least one first LED (141) of the first LED type and at least one second LED (142) of the second LED type. A first LED of the at least one first LED of the third region is located next to a second LED of the second region. A second LED of the at least one second LED of the third region is located next to a first LED of the first region.
