Abstract:
A High Intensity Discharge (HID) lamp includes a discharge chamber disposed within an anti-oxidation envelope and protected by a shroud. The shroud encloses the anti-oxidation envelope and thereby the discharge chamber to prevent the emission of fragments in the event that the discharge chamber fails. The shroud is positioned around the anti-oxidation envelope by a compressed spring at one end of the envelope tensioned against a collar attaching the other end of the envelope to a base of the lamp.
