Definitions
- the invention relates to a mercury vapor discharge lamp with a lamp vessel, in the discharge space at least one amalgam deposit is arranged.
- Such a mercury vapor discharge lamp is known, for example, from EP 1 160 827 A1.
- These conventional discharge lamps have a lamp vessel with a discharge space in the two diametrically arranged electrode coil protrude, between which forms a gas discharge during lamp operation.
- an ionizable, mercury-containing filling is included in the discharge space of the lamp vessel.
- the light output of such lamps is essentially dependent on the mercury vapor pressure in the lamp vessel, the control of the mercury vapor pressure being carried out by amalgam depots mounted in the discharge vessel, which are each heated by one of the electrode coils. The resulting decoupling of the mercury vapor pressure from the outside temperature allows the use of the discharge lamp in an extremely wide temperature range.

- the at least one flap is thermally closed from a certain minimum temperature.
- the damper opens to control the Hg vapor pressure in the lamp.
- the lamps according to the invention are compatible with conventional lamps used.
- This solution has over the prior art according to EP 1 160 827 Al the advantage that the receptacle manufacturing technology simply formed separately and then mounted in the discharge vessel, so that no glass melting technique for forming the receptacle is required.
- the at least one thermally actuated flap of the A-malgamage examples is preferably at a temperature of less than about 70 0 C to 90 0 C, in particular closed less than 80 0 C and opened at higher temperatures.
- the flap is formed, at least in sections, from a thermobimetal or a shape memory alloy.
- a lid of the receptacle is designed as a thermally actuated single flap.
- the lid is preferably formed completely from a thermobimetal or a shape-memory alloys and is attached in sections to the receptacle in such a way that it opens and closes the receptacle in a temperature-dependent manner.
- the at least one flap can advantageously be formed integrally with the receptacle in the solution according to the invention in terms of manufacturing technology.
- the receptacle has a plurality of thermally-actuated flaps (louvers) which are each independently movable.
- the flaps are preferably introduced by a punching and / or cutting process in a Bimetalltechnikstoff or a shape memory alloys of the receptacle.
- a lid of the receptacle is formed of a bimetallic material and provided with a plurality of individual flaps.
- the entire circumference of the lid in this solution is container for example, fixed by gluing, soldering or welding.
- the receptacle may be formed of a different material than the lid.
- a de- diskel of the receptacle is formed as a single flap, which is approximately conical in the closed state and closes an opening of the receptacle and in the open state is approximately flat and the opening of the receptacle at least partially releases.
- the lid is preferably fastened approximately centrally via a fastening element to the receptacle.
- the receptacle is preferably arranged adjacent to the electrode filaments in the discharge space and is in thermal contact with an inventive embodiment of a lamp with electrode filaments.
- Figure 1 is a schematic representation of a discharge lamp according to a first embodiment of the invention with a single flap;
- FIG. 2 shows an illustration of the discharge lamp from FIG. 1 with the single flap open
- FIG 3 is a schematic representation of a lid of a receptacle with a plurality of flaps according to a second embodiment of a lamp according to the invention
- Figure 4 is an illustration of the lid of Figure 3 with the flaps open;
- FIG. 5 shows a schematic representation of a receptacle with a single flap according to a third exemplary embodiment of a lamp according to the invention
- FIG. 6 is an illustration of the receptacle of FIG. 5 with the individual flap open.
- FIG. 1 shows a schematic representation of a mercury vapor discharge lamp 1 according to the invention, designed as a fluorescent lamp.
- This has an approximately rod-shaped or tubular lamp vessel 2 made of glass, which is provided with a phosphor layer, not shown.
- the lamp vessel 2 has a discharge space 6 which is sealed on both sides by base parts (glass dome) 4, into which two diametrically arranged electrode coils 8 protrude, between which a gas discharge is formed during lamp operation. For reasons of clarity, only one end section of the discharge lamp 1 is shown.
- the electrode coils 8 are each connected to contact pins 14, 16 via electrical supply leads 10, 12, which pass through the base parts 4 and, in conjunction with a corresponding lampholder of a luminaire (not shown), provide a stable mechanical hold of the fluorescent lamp 1 and a ne secure electrical contact allow.
- an ionizable filling is included, which consists essentially of one or more noble gases and a small amount of mercury.
- an amalgam deposit 18 is designed as a separate component introduced about rectangular receptacle 20 which is adjacent to the electrode coil 8 and is in thermal contact therewith.
- the receptacle 20 is connected for example by welding or a clamping technique with a first leg 22 of an approximately U-shaped retaining wire 24 which is melted over a second leg 26 in the base part 4 the front side.
- the receptacle 20 is arranged at a distance of about 4 to 14 mm in front of or behind the electrode coil 8.
- a lid 28 of the receptacle 20 is formed as a thermally actuated individual flap 30. This is used for Auslass capitaung of mercury vapor from the receptacle 20 in the discharge chamber 6 and the controlled absorption of mercury vapor through the amalgam reservoir 18 in the receptacle 20.
- the individual flap 30 is formed in the illustrated embodiment of a bimetallic strip and is at a temperature of less than about 80 0 C in its illustrated closed position, in which the receptacle 20 is closed substantially gas-tight.
- the individual flap 30 of a shape memory alloys (memory metal), wherein a deformation of the flap material is achieved by heating, which leads to a temperature-dependent opening and closing of the flap.

- the single flap 30 made of bimetal is heated by the discharge heat, it starts to open.
- the individual flap 30 is in its illustrated open position. With the flap 30 open, mercury vapor, as indicated by arrows, can escape into the discharge space 6 to control the Hg vapor pressure therein.
- the flap 30 is advantageously designed in one piece with the receptacle 20. After switching off the lamp 1, this cools down, with the individual flap 30 closes steadily. At a temperature of less than about 80 0 C, the individual flap 30 is again in its closed position shown in Figure 1, in which the receptacle 20 is closed substantially gas-tight, so that the mercury remains at least partially in the lamp vessel 2 and before the suction of the Amalgam depots 18 is protected.
- the receptacle not shown, in this variant has a multiplicity of thermally actuated flaps (lamella) 36 which are each movable independently of one another.
- the flaps 36 are preferably introduced by a punching or cutting process in a Bimetalltechnikstoff or a shape memory alloys of the receptacle.

The entire circumference of the lid 34 is fixed after the introduction of the amalgam deposit in the receptacle, for example by gluing, soldering or welding, on the receptacle, which may consist of a different material than the cover 34.
- FIG. 4 which shows a representation of the cover 34 from FIG. 3 with the flaps 36 open, these are connected to the cover 34 via a narrow side 38.
- the flaps 36 begin to open, so that, as indicated by arrows, mercury vapor can escape into the discharge space 6 in order to control the Hg vapor pressure therein.
- the flaps are in their open position shown.
- the flaps 36 are advantageously formed in one piece with the cover 34 and introduced into the cover by a punching or cutting process.
- FIG. 5 shows a schematic representation of a receptacle 40 according to a third embodiment, in which a cover 42 of the approximately cylindrical receptacle 40 is formed as a single flap 44 of a shape memory alloys, which closed at a temperature of less than about 80 0 C in the illustrated State in which it is approximately conical in shape and an opening 46 (see Figure 6) of the receptacle 40 radially overlaps and closes.
