Abstract

PURPOSE:To dispense with a midget lamp for dim light, by changing a glow discharge circuit for causing glow discharge between a filament lead wire and an auxiliary electrode located near a filament and a light-on circuit for each other through a switch. CONSTITUTION:When a rotary contact a is brought into touch with a fixed contact b by operating the switch 6, a glow switch 3 is energized to light on a fluorescent lamp 1. When the rotary contact a is brought into touch with a fixed contact c by operating the switch 6, the fluorescent lamp 1 is lighted off and the glow discharge is caused between the auxiliary electrode 9 and the lead wire 8 of the lamp 1 to effect dim illumination. When the rotary contact a is brought into touch with a disconnected contact d by operating the switch 6 further, no light is emitted.
