PURPOSE:To heighten a decoration effect by arranging a plural number of either king of light-transmitting gas-tight casings or high-frequency generators or both kinds of them. CONSTITUTION:A captioned lighting device consists of a plural number of light-transmitting gas-tight casings 21 and a plural number of high-frequency generators 22 while an insulation plate 23 is interposed between the gas-tight casings 21 and the high-frequency generators 22. Further, the high-frequency generators 22 consist of high frequency oscillators 22a and induction coils 22b. The high-frequency oscillators 22a are connected to a power supply 24. A lumi nous color changes when a kind of discharge gas to be sealed inside the light- transmitting gas-tight casings 21 is changed. By the application of a phosphor to a part or the whole of the insides of the light-transmitting and gas-tight casings 21, their luminous colors are made to be different each other. Thereby, a new decoration effect can be obtained. |
