Filling composition for incandescent lamp, and incandescent lamp containing the same and its use |
摘要 |
A filling composition consisting essentially of about 20-75% by volume of xenon gas and about 15-80% by volume of nitrogen gas exhibits excellent luminous characteristics and an extended life expectancy but hardly causes arc discharge when enclosed in incandescent lamp. Incandescent lamps using the filling composition emit a light which is natural, appropriately high in color temperature, excellent in color rendering properties and gentle to the eye when operated at a voltage exceeding their rating but not exceeding 150% thereof.
