- the ends of the lamp vessel are angled parallel to the longitudinal extension of the lamp and fixed in matching openings of a cover plate.
- This type of mounting the Lampenge ⁇ vessel is complex, since the Abwinkein the ends of Lam ⁇ pengefäßes additional steps in the molding of the lamp vessel requires.
- the lamp according to the invention has a curved lamp ⁇ vessel and a holder for this lamp vessel, which he ⁇ inventive flexible or resilient.
- Be ⁇ preferably the invention is applied to lamps whose Lamp vessel is bent substantially helically or spirally.
- Essentially helically or spirally means that the Gr Press ⁇ th part of the lamp vessel a helical line follows, but is not necessarily constant de- ren slope.
- Au ⁇ ßerdem can vary the radius of the helix, so that the helix of the lateral surface of a cone ⁇ blunt and not the surface of a cylinder follows. Due to the flexible or resiliently formed holding tion tolerances can be accommodate ⁇ chen in the dimensions of the lamp vessel, which is usually formed manually.
- the position of the Lampengefä ⁇ SLI relative to a lamp housing or a Lampenso- can be adjusted by means of the ckels flexible or resiliently formed holder.
- the height of the lamp vessel is regulated above the cover plate by adjusting the insertion depth of the angled ends of the lamp vessel in the pass-through openings of the cover plate.
- the flexible or spring-shaped lamp vessel holder according to the invention it is possible to dispense with the abovementioned angled lamp vessel ends according to the prior art, since tolerances in the height of the lamp vessel above the cover plate or above the lamp base or above the lamp housing by means of the flexible or resilient holder can be compensated.
- the lamp vessel regardless of any tolerances in its dimensions, can be brought into contact with a Cyprusabrioskar, which is fixed to the lamp housing and is preferably arranged in the region of the light exit opening of the lamp or the lamp housing.
- a Cyprusabrioskar which is fixed to the lamp housing and is preferably arranged in the region of the light exit opening of the lamp or the lamp housing.
- the invention is preferably applicable to low-pressure discharge lamps.
- the lamp according to the invention has a housing to house, for example, the components of an operating device for the lamp or to form ⁇ with a reflector, and the holder is advantageously connected to this housing in order to determine the position of the lamp vessel relative to the housing ,

- the web of the holder of the lamp according to the invention preferably extends along the longitudinal axis of the Lam ⁇ pe and the clip-like portion of the holder umklam ⁇ mert preferably a longitudinal axis of the cutting portion of the lamp vessel.
- the web is enclosed by the helically or spirally curved lamp vessel and causes no appreciable light shadowing, and the portion of the lamp vessel clasped by the holder is arranged above the longitudinal axis of the center of the lamp vessel.
- the clasped by the holder Ab ⁇ section of the lamp vessel is that portion of the lamp ⁇ vessel, which is the largest distance to the cover ⁇ be sitting. This ensures a stable suspension of the lamp vessel and creates optimum compensation possibilities for the tolerances in the dimensions of the lamp vessel.
- the lamp Wär ⁇ meabriosstoff according to the invention for cooling of the lamp vessel.
- the heat laxatives can be prevents excessive heating of the housing surrounded by the lamp vessel and therein ⁇ closed discharge medium.
- the temperature of the so-called cold spot that is the coolest point determining the vapor pressure of the discharge medium, can be close to its optimum value in the lamp Range of 4O 0 C to 5O 0 C are maintained when the lamp is operated at the usual ambient temperatures of about 0 0 C to 25 0 C.
- the heat dissipation means comprises a grid, which is attached to the housing of the lamp and is in contact with the Lam ⁇ pengefäß.
- the heat can be dissipated from the lamp vessel to the housing.
- the grating is preferably connected to the portion of the Lampenge- fäßes in contact which has the greatest distance from the Abdeckplat ⁇ te.
- this lamp vessel section is preferably also the cold spot of the lamp, so that the grid immediately cools the cold spot.
