To protect the plastic material of a plastic base (2) holding a single-ended high pressure discharge vessel (1) in position with respect to ultraviolet (UV) radiation and heat emitted from the discharge vessel in operation of the lamp, a cover element (7, 7″) of UV radiation and high temperature resistant material, such as a ceramic and preferably aluminum oxide, is positioned between the discharge vessel and the plastic material of the base, located to shield the plastic base from UV and heat radiation. The cover element is, essentially, in disk or plate form, and irremovably connected to the base, for example by pin extensions integral with the base, passing through recessed openings in the cover element, and headed over, in the form of rivet or button heads, for example by ultrasonic welding.

A single-ended high-pressure discharge lamp having a discharge vessel (1) having a projecting, elongated end portion (1d); two current supply leads (3a, 3b) extending from said discharge vessel; a base (2, 2′, 2″) of plastic material; a cover element (7, 7″) of high temperature resistant and UV radi
A single-ended high-pressure discharge lamp having a discharge vessel (1) having a projecting, elongated end portion (1d); two current supply leads (3a, 3b) extending from said discharge vessel; a base (2, 2′, 2″) of plastic material; a cover element (7, 7″) of high temperature resistant and UV radiation resistant, and essentially UV opaque material, positioned to shield the plastic base (2) from UV radiation and from heat radiation emitted from the discharge vessel when the lamp is in use; wherein the lamp base (2, 2′) has a lamp holding portion (2a, 2a″) and a connecting portion (2b, 2b′, 2b″), which is coupled to the holding portion (2a, 2a); wherein electrical terminal connections (8a; 20, 21, 20″, 21″) are provided, secured to the connecting portion; and wherein the connecting portion (2b, 2b′, 2b″) and the holding portion (2a, 2a″) are formed with interdigited separating ribs (15, 16) and interdigited with respect to each other, and separating the current supply leads (3a, 3b) and the respective electrical terminals (8a) to form a labyrinthene path for creep currents and prevent arc-over upon application of high-voltage pulses to oppositely energized ones of said current supply leads upon starting of the discharge lamp.
