摘要： A double-enveloped lamp (10) has a shield (28) surrounding a light-source capsule (20) within a thick-walled outer envelope (12) so that the lamp (10) may be safely operated without necessity of a protective fixture. In the rare event of a burst of the light-source capsule (20), the shield (28) absorbs and dissipates a portion of the burst energy sufficient to permit the thick-walled outer envelope (12) to remain intact and contain shards and other internal parts within the lamp (10).
In alternate embodiments, the shield (28) may be reinforced, such as with a wire mesh (50), or the outer envelope (12) may be reinforced, such as with a polymer coating, or both. A thin-walled capsule (20) may be employed in combination with a shield (28) and thick outer envelope (12).
A lamp (10) in accordance with the invention provides the unexpected benefits of improved luminous efficacy and better color rendering characteristics, since the presence of an optimally positioned shield (28) causes the operation of the light-source capsule (20) to be more nearly isothermal.
