<P>PROBLEM TO BE SOLVED: To provide a LED lighting lamp having simple construction with a plurality of linear light-emitting parts from few light sources. <P>SOLUTION: The LED lighting system includes the light source, a light guide, and a transparent or translucent lens. The light source is arranged into which light is input from the end face of the light guide. At least at one position on the surface of the light guide, a stepped output part is provided running linearly or curvedly on the surface. The lens covers the light source and the light guide, and has a knurling cut formed on the inner or outer face in non-parallel to the output part. Thus, a plurality of linear light emissions are obtained from one light guide. <P>COPYRIGHT: (C)2010,JPO&INPIT |
