Abstract
PURPOSE:To dispense with a midget lamp and a socket therefor, by changing a fluorescent lamp discharge light-on circuit and a fluorescent lamp filament red-heating light-on circuit for each other through a switch. CONSTITUTION:When a rotary contact b is brought into touch with a fixed contact c by operating the switch 6, a glow switch 3 is energized to perform the discharge light-on of a fluorescent lamp 1. When the rotary contact b is brought into touch with a fixed contact d by operating the switch 6, the discharge circuit of the fluorescent lamp 1 is opened and a circuit consisting of a power source 5, an inductance 7 and a filament 2 is closed to heat only the filament without causing discharge in the fluorescent lamp 1. The value of the inductance 7 is appropriately determined so that the filament 2 can be red-heated as an all-night light.
