PURPOSE:To attain high efficiency in high-frequency lighting of a fluorescent lamp, by combination of special lamp design and special lighting conditions. CONSTITUTION:A fluorescent lamp of 18-30mm. in the internal diameter d of the bulb and 1,380mm. or less of the inter-electrode distance l is applied with a lighting voltage of 10-100kHz of the frequency providing the input power of 0.23- 0.31 Watt per unit length of the positive column. In the fluorescent lamp 1, rare gas such as argon, krypton, and the like is filled at the pressure ranging between 107-333 pascal. When the filled rare gas is of more than 90% argon by volume, such an additional effect is provided that the striped lighting disappears quickly. |
