Embodiment Construction

[0029] figure 1 is a schematic cross-sectional view of a bulb 1 of a high-pressure gas discharge lamp (UHP lamp) of a lighting device according to the invention in a horizontal position. The burner 2 is provided as a single piece, hermetically housed in a discharge space 21 filled with a gas mixture, usually for condensation purposes and comprising components capable of condensing, while its material is usually hard glass or silicon glass, including Two cylindrical, mutually facing regions 22, 23 with a substantially spherical region 24 between them having a diameter in the range of approximately 9 mm. The outer contour of the burner wall has a round shape in the region of the discharge chamber 21 . The discharge space with its electrode arrangement is arranged centrally in region 24 . The electrode arrangement basically comprises a first electrode 41 and a second electrode 42, the tips of said electrodes 41, 42 being separated by about 0.7 mm.

Abstract

The invention relates to a lighting unit comprising at least a high-pressure gas discharge lamp, which comprises at least a lamp bulb (1) with a discharge space (21) in which two electrodes (41, 42) are arranged and in which a gas mixture with ingredients capable of condensation is present, wherein a risk of condensation deposit between and / or on the two electrodes (41, 42) exists, and which comprises an ignition device and a unit for local heating (5) of the lamp bulb (1), characterized in that the lighting unit comprises at least one unit for local cooling (6) of the lamp bulb (1).

Description

technical field [0001] The invention relates to a lighting device comprising at least one high-pressure gas discharge lamp comprising at least one bulb having a discharge space in which two electrodes are arranged and at the same time a gas with condensable components is present in the discharge space Gas mixture, so there is a risk of short circuit between the two electrodes caused by condensation deposits, while the lamp includes an ignition device and a device for local heating of the bulb. Background technique [0002] High-pressure gas discharge lamps (HID or high-intensity discharge lamps), and in particular UHP (Ultra High Performance) lamps are preferably used because of their optical properties, especially for projection purposes. [0003] For this application it is required that the light source be as point as possible, so that the luminous arc formed between the two electrode tips should not exceed a length of about 2.5 mm. Furthermore, the highest possible lumin...
