Title:
LAMP COMPRISING A LAMP BODY AND LINE FEED, WHICH IS GUIDED ALONG THE EXTERIOR OF THE LAMP BODY, AND METHOD FOR PRODUCING THE LAMP
Document Type and Number:
WIPO Patent Application WO2003025456
Kind Code:
A3
Abstract:
The invention relates to a lamp, particularly a high-pressure discharge lamp, comprising a base (24), whereby an upper electric connection (28b) is contacted by a return conductor (27) running along a lamp body (14), and to a method for producing a lamp of this type. According to the invention, the return conductor (27) is provided by a conducting layer (17), which is applied using vacuum technology, in particular, sputtering and which is directly located on the lamp body (14). This results in reducing manufacturing costs associated with the mounting of an isolated return conductor (27) running parallel to the lamp body (14). In addition, the lamp produced in the aforementioned manner reliably functions by virtue of the fact that the conducting layer (17) is not affected by vibrations. This lamp can be used, for example, for headlamps of a motor vehicle.
