    • A lighting apparatus includes a reflector, a light source, and a lens unit. The reflector has an open side, and a reflective surface that extends from a periphery of the open side and that defines a compartment. The light source is disposed in the compartment and emits light toward the reflective surface. The reflective surface reflects the light from the light source towards the open side. The lens unit is disposed to close the open side and permits passage of the light reflected by the reflective surface therethrough. The lens unit includes a central lens portion, and first and second side lens portions respectively disposed on two sides of the central lens portion. The central lens portion and the first and second side lens portions are Fresnel lenses, and are configured to redirect the light passing therethrough to result in rectangularly-distributed illumination outwardly of the lighting apparatus.
    • 照明装置包括反射器,光源和透镜单元。 反射器具有开口侧和从开口侧的周边延伸并且限定隔室的反射表面。 光源设置在隔室中并朝向反射表面发光。 反射表面将来自光源的光朝向开放侧反射。 透镜单元设置成闭合开口侧并允许由反射表面反射的光通过其中。 透镜单元包括中央透镜部分,以及分别设置在中心透镜部分两侧的第一和第二侧透镜部分。 中心透镜部分和第一和第二侧透镜部分是菲涅尔透镜,并且被配置为使通过其的光重定向,从而在照明装置的外侧产生矩形分布的照明。

    • An exemplary illumination device includes a solid-state light source and an anti-glare plate. The solid-state light source is configured for generating light, and the solid-state light source defines a central axis. The anti-glare plate is arranged correspondingly generally adjacent to the solid-state light source. The plate includes an incident surface and an output surface at opposite sides thereof. The output surface has parallel micro-structures each have a length parallel to a first reference axis, and the micro-structures is arranged in two groups at opposite sides of the central axis. The micro-structures are configured for contracting a radiating range of the light entering the plate. Such contraction is along respective opposite directions of a second reference axis, and the second reference axis is substantially perpendicular to the first reference axis.
    • 示例性照明装置包括固态光源和防眩光板。 固态光源被配置为产生光,并且固态光源限定中心轴。 防眩光板通常相对于固态光源相对地布置。 板包括入射表面和在其相对侧的输出表面。 输出表面具有平行的微结构,每个微结构具有平行于第一参考轴的长度,并且微结构在中心轴的相对侧分布成两组。 微结构被配置为收缩进入板的光的辐射范围。 这种收缩沿着第二参考轴线的相反方向,并且第二参考轴线基本上垂直于第一参考轴线。
