<p><P>PROBLEM TO BE SOLVED: To provide an optical axis control system capable of simultaneously carrying out optical axis control of two different lighting fixtures by using one optical axis control switch. <P>SOLUTION: This optical axis control system 20 is furnished with the first lighting fixture 21 to carry out the optical axis control by oscillating a first reflector set free to oscillate by a first driving means, the second lighting fixture 22 to carry out the optical axis control by oscillating a second reflector smaller than the first reflector by a second driving means, an electric power source means 60 to apply driving voltage on the first driving means and the second driving means, an oscillating operation means 25 to simultaneously oscillate the first reflector and the second reflector in the same direction by changing a voltage value output from the electric power source means 60 and voltage control means 23, 24 to control the voltage value of the driving voltage applied on at least one of the first driving means and the second driving means so that optical axes of the first reflector and the second reflector oscillate by the same angle in accordance with oscillating operation of the oscillating operation means 25. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
