ABSTRACT:
A fluorescent dyed polymer member and a light source are structurally arranged in a manner to efficiently gather light from the light source and then transmit the gathered light to a light utilization device. Light from the light source is gathered over a large area that is occupied by the polymer member. This gathered light is transmitted through the polymer member to an edge portion thereof having a relatively small light emitting area. Light is then emitted as an external beam having a cross section that corresponds to the physical shape of the edge of the polymer member, for example a straight of linear footprint of light. The area brightness of this external beam is greater than the area brightness of the initial light source.
