Abstract:
A low glare overhead lighting fixture for a transit vehicle comprises a lighting fixture base assembly for mounting one or more light sources (e.g., LEDs or fluorescent tubes), and a light permeable cover adapted to reduce glare. The light permeable cover may include a light guide embodied as a grid-like structure with holes or perforations for directing the light from the light source in a manner reducing light spread. The light guide may be disposed between a front and rear lens covers. The lighting fixture may also utilize a light permeable cover having an anti-glare surface element, such as a privacy filter screen or mesh which may be formed using microlouver technology. The lighting fixture base assembly may have separate compartments, each lined with a highly reflective coating, housing one or more deeply set LEDs.
