摘要：There is provided a light emitting diode, LED, filament lamp (100) which providesLED filament lamp light (101). The LED filament lamp comprises at least one LED filament(102), at least one further LED (105), an at least partly transmissive envelope (107), and anoptical element (108). The at least one LED filament (102) comprises a carrier (103) whichhas an elongated body and a plurality of LEDs (104) mechanically coupled to the carrier(103). The at least one LED filament (102) is configured to emit LED filament light (104').The LED filament light (104') has a first spectral distribution Sl with a first color point xl,yland a first correlated color temperature Tl. The at least one further LED (105) is

configured to emit further LED light (106) which has a second spectral distribution S2 witha second color point x2,y2. The at least one LED filament (102) and the at least onefurther LED (105) are at least partly enclosed by the at least partly transmissive envelope(107). The optical element (108) is arranged to collimate the further LED light (106) intocollimated further LED light (109). The LED filament lamp light (101) is composed of theLED filament light (104') which has a first spatial distribution (S'1) and the collimatedfurther LED light (109) which has a second spatial distribution (S'2). The first spatialdistribution (S' 1) is broader than the second spatial distribution (S'2). The first spectral

distribution S1 and the second spectral distribution S2 are different and wherein one ormore of (i) xl/x2>l.l, and (ii) xl/x2>l.l and yl/y2>l.l with xl/x2 > yl/y2 applies.
