Capped high-pressure discharge lamp |
摘要 |
The capped high pressure discharge lamp includes a light source (1) having a lamp vessel (1') with a first neck shaped portion (2) to which a lamp cap (30) is fixed. A connection conductor (7) runs alongside the discharge vessel to connect a second current supply conductor (5) extending from a second neck shaped portion (3) to a second contact member (36) of the cap. The lamp vessel (1') is contained by a tubular outer envelope (20), which is filled with air and does not envelope the connection conductor (7). The outer envelope (20, 50) has a narrowing portion (21, 52, 51) which encloses the second current supply conductor (5) or a neck shaped portion (2, 3). The outer envelope is maintained. The lamp is of a simple construction which allows for optimizing the light output or the temperature of the lamp vessel.
