摘要：
A luminescence controlling apparatus includes a rare gas pipe equipped with a pair of electrodes in which rare gas is sealed, a power supply for impressing voltage to the pair of electrodes and an electric charge absorption member for absorbing electrons generated during electric discharge of the rare gas pipe caused by impressing voltage to the pair of electrodes. The absorption member is disposed in the rare gas pipe. The luminescence controlling apparatus further includes a controller for controlling a luminescence amount of the rare gas pipe by adjusting a quantity of electrons absorbed by the electric charge absorption member.
