摘要： A double-ended arc discharge lamp includes a sealed, light-transmissive outer jacket (12,72), a light-transmissive shroud (30,70) mounted within the outer jacket (12,72) and directly supported by the outer jacket (12,72), and an arc discharge tube (10) mounted within the shroud (30,70) The arc tube (10) is typically a metal halide arc discharge tube. In a preferred embodiment, the shroud (30) includes an outwardly extending portion (40,42) at each end. The outwardly extending portions (40,42) space the shroud (30) from the outer jacket (12) and support the shroud (30) within the outer jacket (12). The outwardly extending portions (40,42) of the shroud (30) can be affixed to the outer jacket (12) by fusing. The outer jacket (12) can be provided with inwardly extending dimples (50,52) for locating the shroud (30) with respect to the outer jacket (12). In another embodiment, the outer jacket (72) includes reduced diameter portions (74,75) near each end which are attached to the shroud (70).
