Abstract
A lighting system using piped light is provided for the cargo space of a truck. A light source mounted on the truck body is energized by the truck electrical system through a switch in the cab. Plural lighting fixtures are mounted to the roof of the truck body for illuminating the cargo space. Each lighting fixture receives light which is piped through a separate light guide from the source to the fixture. There are two sets of lighting fixtures each of which is disposed in a linear array extending along a line from the front to the rear of the truck body. The light guides for one set of lighting fixtures are all disposed in a first enclosure and the light guides for the other set of lighting fixtures are all disposed within a second enclosure. Certain sections of the enclosures are provided with a transparent lens and certain light guides within the enclosures emit side light through the lens. A lighting fixture at the rear door of the truck body is provided with an optical switch for turning the lighting fixture on or off.
