PURPOSE:To enable the captioned lamp to be started easily and securely, by setting the product of the sealing pressure of starting rare gas and the distance between electrodes to a specified range of value in the captioned lamp which can be lighted by a commercial source of 100-120V. CONSTITUTION:In the captioned lamp, wherein a glow-starter 21 and a single choke stabilzer 22 are used to incorporate a luminous tube 1 into an outer tube 23, starting rare gas is sealed inside the captioned lamp, and the glow-starter or a solid lighting element is installed to apply a starting voltage to the luminous tube equipped with electrodes at the both ends; when the sealing pressure of said starting rare gas is p (Torr), and said distance between electrodes shall be d (cm), the product of said sealing pressure and said distance between electrodes will be 60-300 (Torr.cm), if said starting gas is argon, 50-300 (Torr.cm) in case of krypton gas and 40-400 (Torr.cm) in case of xenon gas so that the captioned lamp can be started easily and securely. |
