ABSTRACT:
A high pressure, tungsten halogen lamp wherein a predetermined quantity of a gas mixture including an inert gas (e.g., argon) and halogen compound (e.g., methyliodide) constitute the lamp's combined atmosphere. The gas mixture is flowed into the tubular member which ultimately comprises the lamp's envelope and is then cooled sufficiently to form either a pool of liquified gas or, alternatively, a frozen, solidified member. A quantity of nitrogen gas established at a predetermined atmospheric pressure is also flowed into the tubular member while a press sealing operation is accomplished to seal the member. When the lamp is then subjected to normal room temperature, the pool (or solidified member) becomes gasified to produce the elevated internal pressure, which may readily approach three atmospheres.
