Abstract
PURPOSE:To prevent lowering of lamp efficiency and short life advancement by providing a metal reflection film on the outside of an outside tube. CONSTITUTION:The outside of an outside tube 1 made of hard glass is covered with a metal reflection film 3 consisting of, for example, deposition film of aluminum, excepting a front translucent part 2. Even if radiated light from a light emitting tube 6 is irradiated in lighting and light electrons are radiated from a metal which forms the reflection film 3, since the reflection film 3 is formed on the outside of the outside tube 1, the vanishment of natrium to the outside of the light emitting tube 6 based on the light electrons is prevented and the lowering of lamp efficiency can be prevented. And the elevation of lamp voltage short life advancement by the increase of excessive free halogen can be prevented.
