    • The invention relates to a pixel arrangement (20;30) for an emissive device with at least a first emissive pixel and a second emissive pixel, said first emissive pixel and said second emissive pixel having respectively a first emissive area (21;31) and a second emissive area (22;32) adapted to emit light upon excitation. The first emissive area (21;31) is located in a first plane (I) and said second emissive area (22;32) being located in a second plane (II) such that said first emissive area (21;31) and said second emissive area (22;32) at least partially overlap in a viewing direction (A) normal to at least one of said planes (1,11). The first emissive area (21;31) is adapted to emit light with a first polarization direction (P1) and said second emissive area (22;32) is adapted to emit light with a second polarization direction (P2) oriented substantially perpendicular to said first polarization direction (P1). The invention further relates to a display panel and a light source comprising a plurality of such pixel arrangements (20;30).
    • 本发明涉及一种用于具有至少第一发射像素和第二发射像素的发射装置的像素布置(20; 30),所述第一发射像素和所述第二发射像素分别具有第一发射区域(21; 31)和 适于在激发时发光的第二发射区域(22; 32)。 第一发射区域(21; 31)位于第一平面(I)中,并且所述第二发射区域(22; 32)位于第二平面(II)中,使得所述第一发射区域(21; 31)和所述第二发射区域 第二发射区域(22; 32)在垂直于所述平面(1,11)中的至少一个的观察方向(A)上至少部分重叠。 第一发射区域(21; 31)适于发射具有第一偏振方向(P1)的光,并且所述第二发射区域(22; 32)适于发射具有基本垂直于所述第一偏振方向 第一偏振方向(P1)。 本发明还涉及一种显示面板和包括多个这样的像素装置(20; 30)的光源。

    • In a method of lighting at least part of a space, a light emitting diode (LED) string is used. The LED string comprises a first LED segment and at least one further LED segment,which are connected in series, each LED segment comprising at least one LED. The LED string is powered by a rectified AC voltage. The first LED segment is powered when the rectified AC voltage is above a first voltage level, and the first LED segment and the further LED segment are powered when the rectified AC voltage is above a second voltage level higher than the first voltage level. The first LED segment is arranged to radiate light to a first volume of the space, and the further LED segment is arranged to radiate light to a second volume of the space, the first volume being at least partly different from the second volume. The first volume may at least partly overlap the second volume.
    • 在照亮至少一部分空间的方法中,使用发光二极管(LED)串。 LED串包括串联连接的第一LED段和至少一个另外的LED段,每个LED段包括至少一个LED。 LED串由整流的交流电压供电。 当整流的AC电压高于第一电压电平时,第一LED段被供电,并且当整流的AC电压高于高于第一电压电平的第二电压电平时,第一LED段和另外的LED段被供电。 第一LED段布置成将光辐射到空间的第一体积,并且另外的LED区段被布置成将光辐射到空间的第二体积,第一体积与第二体积至少部分不同。 第一体积可以至少部分地与第二体积重叠。
