- 摘要：
- A luminaire having an aperture provides first and second zonal illumination areas. A reflector is disposed about a light source for reflecting a first portion of light emitted from the light source through a first zone of the aperture. A deviator is disposed within the reflector for permitting passage of the first portion of light and for directing a second portion of light emitted from the light source through a second zone of the aperture.
