<p>The capped high-pressure discharge lamp has a discharge vessel (1) having opposite neck-shaped portions (2, 3). A tubular glass sleeve (10) envelopes the discharge vessel and has constrictions (11, 12) coupling the sleeve to a respective neck-shaped portion. The sleeve (10) has an end portion (13) adjacent a constriction (11) at the side thereof which is remote from the other constriction (12), in which end portion a pinch (14) is present. A clamping member (20) having lugs (23) which hold the pinch is secured to a mounting member (40) which is fixed to a cap (30). The pinch provides for a mechanically strong portion to secure the discharge vessel to the cap. The construction is able to withstand heavy shocks which may occur during transport.</p> |
