Abstract: A light emitting module (150) emits light through a light exit window (104) and comprises a base (110), a solid state light emitter (154, 158) and a partially diffusive reflective layer (102). The base (110) has a light reflective surface (112) which faces towards the light exit window (104). The light reflective surface (112) has a base reflection coefficient Rbase which is defined by a ratio between the amount of light that is reflected by the light reflective surface and the amount of light that impinges on the light reflective surface. The solid state light emitter (154, 158) emits light of a first color range (114), comprises a top surface (152, 158) and has a solid state light emitter reflection coefficient R_SSL which is defined by a ratio between the amount of light that is reflected by the solid state emitter (154,156) and the amount of light that impinges on the top surface (152, 158) of the solid state light emitter (1154, 156). A largest linear size dssL of the top surface (106) of the at least one solid state light emitter is defined as the longest distance from a point on the top surface (152, 158) of the at least one solid state light emitter to another point on the top surface (152, 158) of the at least one solid state light emitter along a straight line. The light exit window (104) comprises at least a part of the partially diffusive reflective layer (102). A solid state light emitter area ratio ρSSL is defined as the ratio between the area of the top surface of the at least one solid state light emitter and the area of the light reflective surface of the base. A gap with a distance h is present between the top surface (152, 158) of the at least one solid state light emitter

Abstract: The present invention relates to a LED module which converts pump light from a LED chip (120) to light at another wavelength, which is emitted from the module. The conversion takes place in a portion of a luminescent material (124). The color purity of the LED module is enhanced by reducing any leakage of pump light using a reflector in combination with an absorber. In one embodiment, the absorber is integrated as one or several thin absorbing layers between the layers of a multi-layer reflection filter (126); this may yield an even higher reduction of pump light leakage from the module.
Abstract translation: 本发明涉及将来自LED芯片（120）的泵浦光转换成从模块发射的另一波长的光的LED模块。 转换发生在发光材料（124）的一部分中。 通过使用与吸收器组合的反射器减少泵浦光的任何泄漏来增强LED模块的色纯度。 在一个实施例中，吸收器被集成为多层反射过滤器（126）的层之间的一个或几个薄吸收层; 这可能导致来自模块的泵浦光泄漏更大的降低。

Abstract: An arrangement for providing polarized light to, e.g. a LCD, is disclosed. The arrangement comprises a substrate (201) and a top layer (202). The substrate (201) is preferably optically anisotropic and the top layer (202) is either isotropic or anisotropic. The respective indices of refraction are chosen such that polarization separation occurs at the interface (214) between the substrate (201) and the top layer (202). Furthermore, the indices of refraction are chosen such that there are no restrictions on the angle of incidence (&thgr;i) of the incoming light (L), and hence obviating the need for collimation of the incoming light (L). The top layer (202) comprises light outcoupling structures, internally or externally.
