Abstract
PURPOSE: To enhance the efficiency and reduce noises at the periphery as well as thermal load by encapsulating electric discharge gas in a lamp bulb, whose section has a concentrical double circular airtight space, and furnishing an induction coil wound along the axis of tubing into an endless solenoid.
CONSTITUTION: Existing bulb 10 has a hollow 11 in cylindrical form in its center, wherein its two ends are closed, and has an airtight space 12 with concentrical double circular section. As electric discharge gas, a rare gas such as argon or metal vapor of mercury is encapsulated in this airtight space 11, i.e. in the bulb 10. An induction coil 13 is wound on the bulb 10 one turn in an endless solenoid along the axis of tubing in such a direction as from outer wall to the hollow 2 and outer wall again. Thus the magnetic flux is utilized effectively to accomplish enhancement of the efficiency, reduction of noises and thermal load.
