High pressure discharge lamp.

摘要

An electric discharge lamp has a discharge vessel (11) including pair of opposing planar seals (14) each having a pair of major faces (14a, b) and a pair of minor side faces (14c, d). A containment shield surrounds the discharge vessel (11) and includes a glass sleeve (21) and a helically coiled wire (22) secured on the glass sleeve. The glass sleeve is pinched to ends of the minor side faces (14c, d) of the seals (14) only and substantially does not engage the major faces (14a, b) of the seal. The wire (22) is fixed around the sleeve (21) in an electrically floating manner, e.g. by clamping fit. <IMAGE>
