PURPOSE:To provide a multicolor mood lighting system which is excellent in luminous efficiency and whose service life is long and in which the replacement of a lamp is easy by arranging plural paired electrodes in an electric discharge container holding body, sealing up an electric discharge medium in an electric discharge container, and applying a phosphor to the inner peripheral wall. CONSTITUTION:When high frequency voltage is impressed between respective plane-like electrodes 11a, 11b-13a, 13b, voltage is supplied to an electric discharge medium in an electric discharge container 5 through glass of a dielectric in contact with them or adjacent to them, so that electric discharge is caused. UV radiation generated by this discharge excites phosphor 6a-6c formed on the inner wall of the container 5, and emits red color, blue color, and green color visible beams each having a wave length characteristic of the phosphor from an upper part, an intermediate part and a lower part, and those are outputted from a light output part 7. A light flux is changed according to a voltage value of the impressed high frequency voltage. In this constitution, structure can be simplified and the replacement of a lamp only requires to insert o fit the lamp into a discharge container holding body 8, so that a multicolor mood lighting system, which is excellent in luminous efficiency and whose service life is long and in which the replacement of the lamp is easy, can be provided. |
