Passenger lighting system for mass transit vehicle

摘要

A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of the vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows and a lighting fixture supported in the vehicle along the ceiling surface longitudinally of the vehicle at a position above each row of seats. Below the lighting fixture is provided an elongate advertising card support panel member for receiving and supporting an advertising card. The housing is substantially continuous along the vehicle and supports a plurality of fluorescent tubes mounted in the light housing. Between each tube and the next is provided a web member having an inner surface matching that of the housing and an outer surface butting edges of the individual lens/covers mounted on the light housing. The card support panel member carries adjacent the bottom receptacle thereof an elongate pressure switch strip operable at any point along its length for signalling the driver. The reflector is mainly parabolic with a V-shaped center section acting as a beam splitter and a support for a ground wire. The lens includes two upstanding fins each on a respective side of the tube and each carrying a reflective layer to restrict light from passing toward the aisle and the windows.
