Abstract: A lighting system for preferentially illuminating the seating area of a mass-transit vehicle includes a light fixture with a lamp housing longitudinally disposed above the seating area An electrically energized light source is mounted at least one end of the light fixture. At least one solid-core semi-rigid light pipe extends from and is optically coupled to the light source. The light pipe receives light from the light source, transmits the light along its length, and emits the light laterally into the passenger compartment. The light pipe runs parallel to and is suspended from the lamp housing between the lamp housing and the seating area so that the lamp housing can direct laterally emitted light from the pipe into the seating area.

Abstract: A lighting system using piped light is provided for a compartment such as the cargo space of a truck. An electrically energized light source is mounted adjacent the compartment. A side-fire light pipe is optically coupled to the light source. An elongated light pipe enclosure is disposed around and supports the light pipe. The enclosure comprises an elongated mounting flange adapted to fasten the enclosure to a compartment inner surface, an elongated face panel that extends integrally from along the length of the mounting flange, and a longitudinal elongated channel that is recessed into the face panel. The channel includes parallel opposing channel edges that define a longitudinal gap in the face panel. The channel is configured to receive the light pipe in frictional engagement through the gap. The light pipe can be inserted into the channel after the enclosure has been installed and protects the light pipe from damage during such operations as cargo loading into and cargo unloading from the compartment.

Abstract: A lighting system for preferentially illuminating the seating area of a mass-transit vehicle passenger compartment while minimizing the illumination of an aisle and of side windows of the vehicle. A lighting fixture is mounted in a cornice area of the vehicle above the seating area. The fixture includes an air duct extension panel having an outer edge that connects to a sidewall of the vehicle and extends horizontally inward over the seating area. An elongated lamp housing is integrally formed as a unitary piece with the air duct extension panel and is disposed along an inner edge of the extension panel opposite the outer edge. A face panel connects between a ceiling of the vehicle and the extension panel inner edge. The face panel spaces the lamp housing downward from the vehicle ceiling toward the seating area to maximize seating area illumination. The air duct extension panel spaces the lamp housing inwardly away from the sidewall and side windows to minimize side window illumination.
