Claims

[Scope of Claim for Utility Model Registration] (1) A first lighting fixture that illuminates the entire desk top and a second lighting fixture that partially lights up the desk top are placed in a horizontal row at the front of the lower surface of the shelf board in a study desk with shelves. A curtain board is placed below the front end of the shelf board that hides the front of both lighting fixtures, and both lighting fixtures and the curtain board are installed at the same time so that they can be moved back and forth between the bottom of the shelf board and the front of the shelf board. When the first and second lighting fixtures and the curtain plate are manually moved forward, the second lighting fixture and the curtain plate are tilted to a predetermined angle in the forward direction, and when moving backward, the second lighting fixture and the curtain plate are moved in the opposite direction to that when moving forward. A lighting device for a study desk, characterized in that it is equipped with a tilting drive mechanism that returns it to its original position. (2) The tilting drive mechanism has a guide groove that is fixed to the shelf side and tilts back and forth, and one end that is fixed to the second lighting fixture and the curtain plate and moves back and forth and a tip that is opposite to the guide groove that fits into the guide groove. The arm is provided with a guide roller, and the arm is swung by the guide roller, which moves forward and downward and back and up in the guide groove as the first and second lighting devices move back and forth, thereby driving the second lighting device and the curtain plate in an inclined manner. The lighting device for a study desk according to claim 1, characterized in that:
