    • A light emitting arrangement (100), comprising: • - a light source (101) comprising a light out-coupling surface, adapted to emit light of a first wavelength range; and • - a wavelength converting member (102) capable of converting light of said wavelength range into light of a second wavelength range, the wavelength converting member (102) being arranged at a distance from the light source (101) and centrally aligned with the light out-coupling surface light source (101), and being arranged to receive and partially convert a central portion of the light emitted by the light source (101) while allowing light emitted by the light source (101) in a peripheral direction to pass beside the wavelength converting member (102). In this way the light emitting arrangement (100) provides light of first color in a normal direction and a light of another non-converted color in a peripheral direction, which may give a more realistic impression of daylight.
    • 一种发光装置(100),包括: - 光源(101),包括适于发射第一波长范围的光的出光耦合表面; 和。 - 波长转换构件(102),其能够将所述波长范围的光转换成第二波长范围的光,所述波长转换构件(102)布置在距离所述光源(101)一定距离并且与所述光出口 耦合面光源(101),并且被布置成接收并部分地转换由光源(101)发射的光的中心部分,同时允许光源(101)沿周向发射的光通过 波长转换部件(102)。 以这种方式,发光装置(100)在正常方向上提供第一颜色的光,并在周向方向上提供另一未转换的颜色的光,这可能给出更逼真的日光印象。
