Abstract
A lamp holder has a housing which comprises a base part and a cover part. The cover part, which has contact holes to receive terminals of a high pressure gas discharge lamp to provide access to contact members, is integral with a partition wall which extends inside and outside of the housing between the contact holes. The partition wall which divides the housing into chambers extends into a recess in the base part. The cover part and the base part form curved channels through which electric cables are led to respective contact members. As a result of these measures, the risk of breakdown is avoided, yet the lamp holder structure can be compact.
