摘要	A lighting apparatus for emitting polarized white light, which includes at least a first light source for emitting primary light comprised of one or more first wavelengths and having a first polarization direction; and at least a second light source for emitting secondary light in the first polarization direction, comprised of one or more secondary wavelengths, wherein the first light and the secondary light are combined to produce a polarized white light. The lighting apparatus may further comprise a polarizer for controlling the primary light's intensity, wherein a rotation of the polarizer varies an alignment of its polarization axis with respect to the first polarization direction, which varies transmission of the primary light through the polarizer, which controls a color co-ordinate or hue of the white light.
其他摘要	一种用于发射偏振白光的发光装置，其至少包括用于发射包括一个或多个第一波长并具有第一偏振方向的一次光的第一光源;至少第二光源，用于在第一偏振方向上发射二次光，包括一个或多个次级波长，其中第一光和次级光被组合以产生偏振白光。照明装置还可以包括用于控制初级光强度的偏振器，其中偏振器的旋转改变其偏振轴相对于第一偏振方向的对准，这改变了初级光通过偏振器的透射，其控制了颜色的坐标或白光的色调。
主权项	A white light-emitting device for emitting polarized white light, comprising: one or more Light Emitting Diodes (LEDs), Super Luminescent Diodes (SLDs), or Laser Diodes (LDs) that emit at least blue polarized light; and one or more phosphors for emitting yellow polarized light when optically pumped by the blue polarized light, wherein: the LEDs, SLDs, or LDs are nonpolar or semipolar III-nitride LEDs, SLDs, or LDs; the phosphors have a structure that maintains a polarization of the blue polarized light, so that the yellow polarized light has the polarization of the blue polarized light; and a combination of the blue polarized light and the yellow polarized light is polarized white light having a same polarization as the blue polarized light.
