    摘要: Disclosed is an outdoor luminaire employing as its external lens, panels of one-way reflecting glass. During the day, or with the interior lamp unlit, the panels provide an opaque outer surface reflective of the surroundings. With the lamp lit, the panels act merely as lenses passing the light emitted by the interior lamp. In order to make the luminaire opaque, diagonal baffles are provided to extend from each corner of the luminaire toward the lamp and lamp prismatic refractor. These baffles tend to produce four separate compartments with opaque interior walls to prevent the lamp and internal components from being visible when the lamp is unlit. By making the baffles reflective, a further enhancement of the internal masking is effected while further enhancing the optical characteristics of the luminaire when lit.
