Abstract: A protective device for a lamp, especially a high-pressure xenon discharge lamp or high-pressure mercury vapor discharge lamp, includes a pressurized lamp vessel and a protective envelope which surrounds the lamps in at least some sections, can be fixed to the lamp by two closures that engage around lamp shafts, and is made of a gas-permeable fleece.

Abstract: The invention relates to a unit pack for a linear lamp. The pack is desig as a single-piece tubular folding box. It has four side walls (10, 11, 12, 13) which form a tubular sleeve of trapezoidal cross section. At its top end, the folding box is provided with an integrally formed hanging tab (15).

Abstract: To securely retain a multi-unit folded fluorescent lamp (L) having a gap d, 21d) between adjacent legs of the lamp in position in an elongated box (1'), the box is formed from a blank (1) having a top panel (15) which overlies an intermediate panel (16) of lesser width than the top panel, from which at least a first retention flap (19a) extends in a first gap between the two legs of the lamp. A second retention flap (19b) is cut, along a severing line (19c), from the intermediate panel element (16) and folded along a fold or crease line (21) to fit into the gap between other legs of the discharge vessel or discharge vessel unit of the lamp. The retention flaps (19a, 19b) retain the lamp and support the legs in case of vibration or shock due to transport.
