Cold cathode fluorescent lamp with molybdenum electrode

A cold cathode fluorescent lamp ( 1 ) has feedthrough pins ( 5 ) made from molybdenum or a molybdenum alloy that form a glass-metal seal ( 6 ) with a glass composed of 55-75 wt. % SiO2, 13-25 wt. % B2O3, 0-10 wt. % Al2O3, 5-12 wt. % alkali oxides, 0-3 wt. % alkali earth oxides, 0-5 wt. % ZrO2, 0-10...

Beschreibung
Zusammenfassung:	A cold cathode fluorescent lamp ( 1 ) has feedthrough pins ( 5 ) made from molybdenum or a molybdenum alloy that form a glass-metal seal ( 6 ) with a glass composed of 55-75 wt. % SiO2, 13-25 wt. % B2O3, 0-10 wt. % Al2O3, 5-12 wt. % alkali oxides, 0-3 wt. % alkali earth oxides, 0-5 wt. % ZrO2, 0-10 wt. % TiO2 und 0-5 wt. % remaining oxides. The lamp has hollow cathodes ( 4 ) made from a material of the group molybdenum, molybdenum alloys, niobium, niobium alloys, and the lamp is manufactured in a compact form using conventional manufacturing parameters, and the resulting lamp has crack free, long-term vacuum-tight glass-metal seals.
