<P>PROBLEM TO BE SOLVED: To provide a lens and a lamp fitting forming a lighting fixture which looks different when it is lighted in comparison with when it is not lighted. <P>SOLUTION: This lens used in the lamp fitting includes at least a first lens cut and a second lens cut. The first lens cut and the second lens cut are to diffuse light radiated from a light source as a desired light distribution, and are formed between two guide curves extending in one direction. When the first and second lens cuts are cut by a plane perpendicular to the one direction, the first and second lens cuts are formed as lens cuts in which a curve appearing between two guide curves continuously changes as the cut position shifts from one end side to the other end side. <P>COPYRIGHT: (C)2010,JPO&INPIT |
