Laminates, which are used for cooling the discharge vessel, are fitted to the seals of the ceramic discharge vessel. They are an integral part of the seal.

High-pressure discharge lamp having cooling laminates fitted at the end of the discharge vessel

The invention relates to a metal halide lamp comprising a ceramic discharge vessel (), characterized in that an MoV leadthrough is connected to a PCA element (AlO) by means of a specific adhesive layer containing Al and Mo.

Metal halide lamp with adhesive layer sealing molybdenum/vandium alloy leadthrough

The invention relates to a metal halide lamp comprising a ceramic discharge vessel (), characterized in that a molybdenum leadthrough () is connected to a cermet stopper () via an intermetal interface gradient ().

Metal halide lamp with intermetal interface gradient

The metal halide lamp has a ceramic discharge vessel and contains two groups of metal halides: a first group made up of the emitters and a second group made up of the wetters. The second group comprises at least one of the metal halides of Mg or Yb.

Metal halide lamp

A high-pressure discharge lamp with a ceramic discharge vessel (8) compri a tubular current feedthrough (10) of a metal whose thermal coefficient of expansion is smaller than that of the ceramics. Gas-tightness is obtained by an internal support member (16) located within the current feedthrough (10).

High-pressure discharge lamp

A high pressure discharge lamp has a ceramic discharge vessel (8), whose s are closed with plugs (11). The metallic feedthrough, or a main part of it, has a thermal coefficient of expansion which is smaller than the coefficient of the ceramic. The current feedthrough is gas-tightly sintered directly into the plug.
