<P>PROBLEM TO BE SOLVED: To provide a lighting system with retention accuracy of a lens and optical characteristics free from degradation, when a lens holder holding a lens is fixed to a substrate with a holder fixing means. <P>SOLUTION: The lens holder 6 is provided with a lens holding part 21 elastically holding a flange part 17 of a lens 5, a holder fixing part 22 positioned so as to surround the lens holding part 21 and press-fixed to a substrate 3 with a holder fixing means 2, and a coupling part for partially connecting the lens holding part 21 and the holder fixing part 22. A height of the holder fixing part 22 from the substrate 3 is to be larger than that of the lens holding part 21 from the substrate 3, so that the lens holding part 21 shall not come in contact with the holder fixing means 2. Even if the holder fixing part 22 is deformed in a height direction by the holder fixing means 2, the deformation of the holder fixing part 22 shall not affect the lens holding part 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
