1. the control appliance of a light signal switch, this light signal switch comprises first reflection mirror array and second reflection mirror array that has a plurality of arrangements pitching speculum in one plane respectively, and utilize described first and second reflection mirror arrays sequentially to reflect input optical signal to export this light signal from ad-hoc location, each pitching speculum has the controlled reflecting surface of its angle respectively, this control appliance is used to control the angle of reflecting surface of each pitching speculum of described first and second reflection mirror arrays, and this control appliance comprises:

  • The luminous power detecting unit is used to detect the power from the light signal of described ad-hoc location output;

    AndThe angle control unit, be used to control the angle of at least one reflecting surface of pitching speculum of described first and second reflection mirror arrays of this light signal of reflection, so that the luminous power that described luminous power detecting unit detects becomes the constant target value that is provided with corresponding to described ad-hoc location.
