Abstract

A fixture for a fluorescent lamp includes a diffuser panel. The diffuser panel has a frame and longitudinal elements supported by the frame and spaced apart from one another. At least some of the elements are constructed of a material to allow diffusion of impinging light. Preferred materials are translucent or transparent, such as glass or plastic. The diffuser panel also functions as an air diffuser. Provision of a nozzle in the base of the fixture allows air to flow through the panel by a sucking effect created by high velocity forced air flowing through the nozzle. This results in fixture cleaning and temperature equalization. The fixture is particularly adapted to be mounted in a moving vehicle. For this purpose, the panel is designed to be tamper-resistant and to provide easy maintenance. The diffuser panel, when a latch is opened, may be lowered by rotation to provide access to the lamp and ballast. When the fixture is installed in a public vehicle, a handrail is provided which forms part of the panel lowering mechanism.
