<P>PROBLEM TO BE SOLVED: To provide a lighting system 11 capable of securing and keeping regular holding power for a light source unit 12. <P>SOLUTION: A spherical part 24 of a light source unit body 22 is sandwiched between a holder 13 and a retainer 14, and the holder 13 and the retainer 14 are connected through a connection means 15. Frictional resistance among the spherical part 24 of the light source unit body 22, the holder 13 and the retainer 14 is increased, and sufficient holding power for the light source unit 12 is secured. The regular holding power for the light source unit 12 is kept by energizing the holder 13 and the retainer 14 in a direction for sandwiching the light source unit body 22 between them by an elastic part 55 of the connection means 15. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
