Abstract
An arrangement and method for providing an elongated light source, such as for illuminating a sign or the interior of a mass transit vehicle or other display, which includes emitting light from a light source into an elongated tubular member having a portion lined with a high reflectance film formed with longitudinal prismatic lenses, the tubular member having a light-transmissive opening along its length, with a diffusing medium substantially diametrically opposite such opening, and optionally a reflector or a second light source at one end of the tubular member. The emitted light propagates in the inner tubular member by reflecting from the high reflectance lining and the reflector to impinge on the diffusing medium and thereby transmit light outwardly through the light-transmissive opening so as to project light against a sign or advertising card or like object. Several units may be placed end-to-end to provide a longer illuminating arrangement. A single light source may be used to illuminate two adjoining units.
