Electric high-pressure discharge lamp for use as a motor vehicle headlamp.

摘要

The lamp has a holder body (20) in which an end portion (5) of the discharge vessel (1) is secured. A light-receiving window (13) of a photoelectrical element (14) is positioned inside the holder body (20) and aimed at the first end portion (5) of the discharge vessel (1). The photoelectrical element may be connected to the control of the electric supply of the lamp in order to obtain a high luminous flux within a short period after ignition of the lamp. External factors have little influence on the control action thanks to the position of the window (13).
