LIGHTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a lighting system capable of precisely positioning each member without lowering an assembling property.

SOLUTION: A lens optical system 21 is constituted by interposing a first spacer 23 between a collimation lens 22 and an LED substrate 11 and interposing a second spacer 25 between the collimation lens 22 and a fly eye lens 24. A case body 20 to store the lens optical system 21 is constituted of a cylindrical case body furnished with an introversive flange 20a on its head end part. It is possible to precisely position each of the constitutional members without lowering the assembling property by inserting each of the constitutional members of the lens optical system 21 into the case body 20 through an opening part 20c on the side of a base part and holding each of the constitutional members in the case body 20 by welding them on each other with pressure between the introversive flange 20a and the LED substrate 11 of a light source unit 10.
