Abstract:
A reflector high-pressure discharge lamp unit (1) for applications in the fields of radiation and illuminating engineering, in particular for applications in the field of projection, comprising:a reflector (2) with a reflector neck (16), and having a radiation/light exit opening and an axis, a high-pressure discharge lamp (1) arranged on the axis of the reflector (2) and having a lamp bulb (8) and two lamp shanks (9, 10) which are arranged at the two opposite ends of the lamp bulb (8) and into which electrode systems (13, 14) are sealed in a gastight fashion via metal foils (11, 12), one lamp shank (9) being fastened in the reflector neck (16), a first base part (4) made from a non-conducting material and connected to the reflector neck (16), a second base part (5), arranged in front of the radiation/light exit opening of the reflector (2) and in the form of a mechanical auxiliary part made from non-conducting material, first and second supply leads (17, 18), of which one end is electrically connected to the metal foils (11, 12) in the lamp shanks (9, 10), and the other end is guided directly or via a connecting line to the first base part (4) or second base part (5), and first and second high-voltage cables (6, 7) for connecting the high-pressure discharge lamp (1) to a starting device and ballast, which are electrically connected to the supply leads (17), â€ƒcharacterized in that the end of the second supply lead (18), led to the second base part (5), or the end of the connecting line is electrically connected directly to the end of the corresponding second high-voltage cable (7), and this free connecting region is embedded in the second base part (5).
