Title:
LIGHTING SYSTEM FOR MASS-TRANSIT VEHICLES
Document Type and Number:
WIPO Patent Application WO2000034708
Kind Code:
A9
Abstract:
A lighting system (20, 20') for preferentially illuminating the seating area (38) of a mass-transit vehicle (22) includes a light fixture (42) with a lamp housing (52) longitudinally disposed above the seating area (38). An electrically energized light source (74) is mounted at at least one end of the light fixture (42). At least one solid-core semi-rigid light pipe (76, 78, 80) extends from and is optically coupled to the light source (74). The light pipe (76, 78, 80) receives light from the light source (74), transmits the light along its length, and emits the light laterally into the passenger compartment (24). The light pipe (76, 78, 80) runs parallel to and is suspended from the lamp housing (52) between the lamp housing (52) and the seating area (38) so that the lamp housing (52) can direct laterally emitted light from the pipe (76, 78, 80) into the seating area (38). The light pipe (76, 78, 80) can be supported by a hanger device (92). Additionally, the light source (74) can comprise a dual-port light source (74k).
