Definitions
- the invention is based on a method for producing a lamp according to the preamble of claim 1. It is a method for producing a lamp with a lamp vessel which has at least one open, cylindrical end into which an electrode system is inserted and which is then sealed gastight.
- the electrode systems are introduced into the lamp vessels by means of a plate melting and melted in a gas-tight manner. Only with very small tube diameters is it possible to squeeze the electrode system into the open end or ends.
- the plate melting process requires an additional pump tube in the plate, through which the lamps are pumped, rinsed and filled with the required substances. Since this pump tube has to be sealed gas-tight after the filling process, this results in an additional manufacturing step.
- a metal or plastic base is also required, which can be cemented onto the tongue is attached. Melting the plate and fixing the base require complex machine technology.
- the lamp vessel with the at least one open cylindrical end is inserted in a gas-tight manner in a pump head, the pump head carrying a closure plate with the electrode system and the connecting pins on a holder such that when the lamp vessel is used in the pump head, the closure plate is perpendicular to the axis of the cylindrical end of the lamp vessel comes to rest.
- the holder can be moved along the axis of the lamp vessel.
- the closure plate has an outer contour that is a little smaller than the inner contour of the open end of the lamp vessel. This makes it possible to pump the lamp vessel via the pump head, rinse it and fill it with gases and possibly other filling substances in the desired amount.
- the method is simplest when the cylindrical end of the lamp vessel has a circular inner contour and the closure plate has a circular edge.
- the energy source rotates around the lamp vessel and the closure plate during the heating process.
- the lamp vessel and the sealing plate rotate at the energy source during the heating process.
- a gas burner is preferably used as the energy source.
- the lamp to be manufactured is a fluorescent lamp with a tubular lamp vessel with a continuous circular cross section and a glass tube is used at the ends of the lamp, the two ends of which are inserted into the pump head at the same time or one after the other a bracket attached circular locking plate with the electrode system and the connecting pins used.
- the electrode system advantageously consists of a holder and a filament attached to it, which are attached on the side of the closure plate facing away from the open end of the lamp vessel.
- electrical Jamaical connecting pins attached and electrically connected to the coil via power supply lines.
- the closure plate is advantageously made of insulating glass. However, it can also consist of metal, in which case the current leads in the lead-through area of the closure plate are made of insulating material such as e.g. Glass solder are surrounded. However, the closure plate can also consist of a glass plate, on the edge of which a metal ring is attached.
- the current leads for forming the emitter are advantageously electrically connected to a current source.
- the invention also relates to a lamp produced by the present method.
- FIG. 1 shows the process setup at the beginning of the production process according to the invention for the production of a tubular low-pressure discharge lamp
- Figure 2 shows the process structure for heating the closure plate and lamp vessel
- FIG. 3 shows the process setup after the protruding end of the lamp vessel has been separated
- FIG. 1 shows the process setup at the beginning of the production process according to the invention for the production of a tubular low-pressure discharge lamp.
- the tubular lamp vessel 1 with a circular inner cross section is inserted with its two ends in a pump head 2, the two seals 3, 4 ensuring a vacuum-tight seal with respect to the surroundings.
- a pump head 2 For the sake of simplicity, only one end 5 inserted into a pump head 2 is shown in the present FIGS. 1 to 3.
- the pump head 2 also carries on a holder 6 a sealing plate 7 made of glass, on the side facing away from the pump head 2 an electrode system consisting of a helix 8 and an integration cap 9 and on the side facing the pump head 2 connecting pins 10 which are connected via current leads 11 are connected to the coil 8 are attached.
- the connection pins 10 for forming a getter material are electrically contacted via cables 12.
- the tubular lamp vessel 1 can now be pumped through an opening 13 on the pump head 2, rinsed and filled with the required fillers, which is indicated by the double arrow.
- FIG. 2 shows the following process step of the inventive method.
- the process setup is essentially the same as the process setup shown in FIG. 1.
- an energy source in the form of a gas burner 14 is arranged in the position of the closure plate 7.
- the lamp vessel 1 at this point and the edge of the closure plate 7 are heated until the lamp vessel 1 falls into place and connects to the edge of the closure plate 7 in a gastight manner.
- the further process step shows the end 14 separated from the gas-tightly closed lamp vessel 1.
- the pump head 2 is flooded with atmospheric air via the opening 13, the pump head 2 can be moved by moving the pump head 2 End 14 is removed from the melted lamp 15 and separated and the separation point on the lamp 15 are fused. After the holder 6 has been pulled off further from the connecting pins 10 and the pump head 2, the finished lamp 15 and, after the seal 3 has been loosened, the end 14 can be removed.
- the method according to the invention can also be used for lamps with a pear-shaped lamp vessel, such as an incandescent lamp.
- FIG. 1 a shows the process setup for producing an incandescent lamp at the start of the process, the setup largely matching the process setup shown in FIG. 1 for tubular low-pressure discharge lamps. For this reason, the same parts of the construction are designated with the same numbers as in FIG. 1.
- a pear-shaped lamp vessel 16 with a circular cylindrical open end 17 is inserted into the pump head 2 here.
- the closure plate 18 in this case carries a filament 19 on the side facing away from the pump head 2, which is connected to the connecting pins 21 via current leads 20.
- the sequence of the further process for producing an incandescent lamp corresponds in its basic process steps to the process for producing a tubular low-pressure discharge lamp. The further process steps were therefore not presented.
