Abstract:
A high-pressure gas discharge lamp 10 is described with a sealed discharge vessel 20 with an inner discharge space 22. Two electrodes 24 project into the discharge space 22. The filling in the discharge space 22 comprises metal halides and a rare gas. In order to provide a lamp with good environmental properties suited for automotive use, in particular with good lumen maintenance, the filling is free of Hg and Th and comprises halides in an amount of 7.1-11.4 μg/mm3 of the volume of the discharge space 22. The halides comprise at least NaI and ScI3, provided in such amounts that a ratio of the masses of NaI to ScI3 is 1.2-1.6.

The lamp, particularly the high pressure discharge lamp, comprises a socket (10) made of an insulating material, a burner (12) for emitting light mechanically connected to the socket, and a backlead wire (14) connected to the burner (12), wherein the socket (10) comprises a color with a weighted absorption of
Abstract:
A high-pressure gas discharge lamp (HID [high intensity discharge] lamp) is described which is in particular free from mercury and suitable for use in automobile technology. The lamp is remarkable in particular for a discharge space (2) which has a volume which is reduced by a given factor in comparison with the volume of the discharge space of known mercury-containing discharge lamps. The quantity of the light-generating substances in the discharge space (2) is reduced by the same factor in the simplest case, or even more strongly. This avoids the risk of an impairment of the imaging properties of the lamp because of non-evaporated light-generating substances which may shade off a portion of the luminous discharge arc (21) and/or the tips of the electrodes (3).
Abstract:
The invention relates to a discharge lamp with a reflector (1) and a burner (2), wherein the reflector (1) comprises at least a reflective contour (3) and a hollow reflector neck (4), the burner (2) is arranged in centered manner in the reflector (1) and the reflector (1) and the lower part (2.1) of the burner (2) are connected firmly together by a mechanical fastening unit and, during assembly, the burner (2) may be guided through the reflector neck (4), starting with its upper part (2.2), and the mechanical fastening unit exhibits such play in the x, y and z directions that the burner (2) can be brought into a defined position relative to the reflector during assembly.

Abstract:
The invention describes a mercury-free high-intensity gas-discharge lamp (1) comprising a discharge vessel (5) enclosing a fill gas in a discharge chamber (2) and comprising a pair of electrodes (3, 4) extending into the discharge chamber (2), for which lamp (1) the fill gas is derived from a salt fill introduced into the discharge chamber (2) prior to sealing, which salt fill is free of scandium and includes a halide composition comprising a sodium halide to a proportion of at least 65 wt % and at most 97.2 wt %,a thallium halide to a proportion of at least 2 wt % and at most 25 wt %, and an indium halide to a proportion of at least 0.5 wt % and at most 25 wt %. Eliminating the highly reactive scandium from the fill gas significantly improves lumen maintenance.
