Patent number: 4945288Abstract: A double jacket arc lamp is disclosed. A double jacket arc lamp may be formed with an electric lamp capsule having an inner light transmissive envelope with electrical lead extending from the inner envelope through a first seal, and a second light transmissive envelope sealed to the inner envelope at a second seal to substantially surround the electric lamp capsule and form an enclosed volume between a portion of the exterior of the inner envelope and the interior of the outer envelope, and leaving the leads unenclosed by the outer envelope. The lamp leads then pass through only one seal, and have no portions exposed in the intermediate insulating volume. The inner capsule is then aligned once, while still being for the most part protected by a double envelope.Type: GrantFiled: December 21, 1988Date of Patent: July 31, 1990Assignee: GTE Products CorporationInventors: Merle E.

Patent number: 4922155Abstract: A fail safe feature for long life reduced voltage lamps including diodes id disclosed. As known, a low wattage lamp may designed for longer life by using a lower root mean square design voltage. The root means square voltage of the alternating source current may be lowered by including a rectifying element, and a fuse may be included in series with the lamp to safely interrupt the circuit. By further including a one-way shunt oriented oppositely to the rectifier, in parallel with the lamp, and intermediate the rectifier and fuse, on failure of rectifier, unrectified current blows the fuse. If the rectifying diode fails, substantially all of the current is shunted to the fuse during the failed half of the current cycle, thereby blowing the fuse, and safely failing the lamp.Type: GrantFiled: June 22, 1988Date of Patent: May 1, 1990Assignee: GTE Products CorporationInventors: Merle E.

Patent number: 4535268Abstract: 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.Type: GrantFiled: March 30, 1983Date of Patent: August 13, 1985Assignee: GTE Products CorporationInventors: Merle E.
