Abstract

An elongated flexible lighting system according to the present invention comprises an array of light sources that are illuminated by electric power. It further comprises an elongated translucent extrusion of flexible material. The array of light sources is integral to the extrusion with said extrusion transmitting and dispersing the light from the array such that the lighting system gives the appearance that the array of light sources is a continuous light source. The elongated lighting system can be used for many different applications including, but not limited to, the lighting of structural features and illumination of sign features.
