  • High-pressure discharge lamp having a cooling element
    Patent number: 8519623
    Abstract: A high-pressure discharge lamp comprising two electrodes (16, 18), which are arranged facing each other in a discharge vessel (6) and are each in electric contact via a current feed system (20, 24, 26, 28, 30), wherein each current feed system penetrates a piston shaft (9,10) arranged in a gastight manner on the discharge vessel (6), wherein in the region of the outer current feed (28, 30) of at least one piston shaft (9) a cooling element (12) is arranged, and wherein the outer current feed (28, 30) and the cooling element (12) are in direct thermal and electric contact.
