    • A luminaire (100) includes a longitudinal axis, a partially transmissive, partially reflective cover (210) perpendicular to the longitudinal axis, and a reflective upper surface (220) generally parallel to the cover (210). The upper surface (220) and the cover (210) define a volume (230) there between. The volume (230) has a lateral periphery (240). The luminaire (100) includes a plurality of solid state light sources (250) disposed on the periphery (240), each one configured to emit light into the volume (230). In some examples, the periphery is angled away from the longitudinal axis. In some examples, the emitted light has an angular distribution centered around a surface normal, where the surface normal is angled with respect to the longitudinal axis and extends toward the cover. In some examples, at least one of the cover and the reflective upper surface is curved. In some examples, at least one of the cover and the reflective upper surface includes regions having different reflectivity.
    • 灯具(100)包括垂直于纵向轴线的纵向轴线,部分透射的,部分反射的盖子(210)以及大致平行于盖子(210)的反射上表面(220)。 上表面(220)和盖(210)之间限定一个体积(230)。 体积(230)具有侧向周边(240)。 照明器(100)包括设置在周边(240)上的多个固态光源(250),每个固态光源被配置为将光发射到容积(230)中。 在一些实例中,周边与纵向轴线成一定角度。 在一些示例中,发射的光具有以表面法线为中心的角分布,其中表面法线相对于纵向轴线成角度并且朝向盖延伸。 在一些示例中,盖和反射上表面中的至少一个是弯曲的。 在一些示例中,盖和反射上表面中的至少一个包括具有不同反射率的区域。

    • The invention relates to alighting apparatus comprising a light emission unit (2) for emitting light (3) from an emission surface (4) in a main emission direction (6),and an outcoupling unit (7) for coupling the light out of the light emission unit. The outcoupling unit comprises a first surface (8) having a first central region (9) optically coupled to the emission surface and a first peripheral region (10)enclosing the first central region, and a second surface (11) opposite to the first surface. The peripheral regions can be structured, wherein the ratio of a) the area of the emission surface to b) the area of the first surface or the second surface is smaller than 0.5. This configuration can significantly decrease the likelihood of reabsorption of light by the emission surface, thereby increasing the efficiency of extracting light out of the lighting apparatus.
