Claims

[Scope of utility model registration request]

A light-shielding system in which multiple oblong holes that are long in the front and back direction are made transparent in the lamp case in front of the light source, a sliding guide is extended from the lens stand that holds the lens inside the lamp case, and the long holes are hidden outside the lamp case. Set up a board,
A fixed elongated hole is formed in the light shielding plate at a position different from the elongated hole and substantially parallel to the elongated hole, and a sliding guide is loosely inserted into the elongated hole, and a plurality of sliding guide groups protrude from the elongated hole to the outside of the lamp case. A lens moving structure for a lighting device, which is constructed by installing a board on the board, providing a screw hole in the board, screwing a fixing screw loosely inserted into a long fixing hole into the screw hole, and press-contacting the fixing screw to a lamp case so that it can be separated freely.
