Definitions
- the present invention relates to a method for manufacturing a display tube for the light display technology and the Illumination of advertising forms, one after this Processed display tube, a system from one such display tube with associated ballast as well a method for operating such a display tube.
- the luminous efficacy of high-voltage fluorescent tubes is very low, it is between 6 and 15 lm / W. To adequate and effective illumination results, especially with arrangement behind translucent materials practice Multiple parallel arrangements of high-voltage fluorescent tubes common. This leads to high costs for material components and wage benefits.
- FIG. 1a shows an example of the use of a high-voltage tube according to the prior art to represent a block letter L.
- the high-voltage tube 10 which is arranged in a translucent form 12 to be illuminated for this purpose, is connected to the secondary side of a high-voltage transformer 11. While the voltage U 1 on the primary side of the transformer 11 corresponds to the mains voltage, the voltage U 2 on the secondary side is calculated from the cathode case (approx. 300 V per tube) plus the burning voltage requirement of approx. 400 V per meter of pipe length.
- Figure 1b shows the use as an alternative prior art of standard fluorescent lamps for illuminating illuminated signs Displays as a replacement for high-voltage fluorescent tubes.
- Low voltage standard fluorescent lamps are in elongated, d. H. straight, circular, U-shaped or compact shape available.
- Figure 1b shows the use of two low voltage standard fluorescent lamps 14 and 16 for illumination a translucent shape 18 to form a block letter L to represent. If the translucent shape 18 is dispensed with there would be an aesthetic problem because of the desired shape can only be represented in a very simplified manner and the connection and mounting technology would also be disruptively visible.
- DE-PS 892 505 also describes a fluorescent lamp which is produced by machine bending.
- DD 267 349 describes a method for rinsing and filling a low pressure gas discharge lamp, the pumping Gases into the glass on one side, on the other Side out of the glass.

- Pure neon is preferred as the gas or gas mixture, for so-called Red discharge systems that can only glow red, or a mixture of neon argon nitrogen in combination with Mercury, for so-called blue discharge systems, all of them Luminous colors allow for consideration.
- a display tube made by this process which by no means Lighting purposes, only display purposes also has a number of important advantages.
- display tubes could have a ratio from luminous flux to electrical power from 30 to 70 lm / W (luminous efficacy) can be realized. So that's the energy balance many times better than with high-voltage fluorescent tubes according to the state of the art.
- a display tube manufactured in this way is only with low voltage operated, which is why the maximum voltage occurring is in the range of the mains voltage. This results in much lower requirements on the assembly effort, the Security requirements and with regard to the use of materials. While in the prior art according to the high-voltage fluorescent tubes a neon specialist with approval for installation the responsible local energy supply company (High voltage! Was necessary, can according to the present invention any electrician connect such a tube, In particular, display tubes according to the invention can be used the low voltage installation regulations and are therefore unproblematic in terms of safety. This everything results in significantly lower assembly costs.

- the dimming device can thus for example, the light output can be increased at dusk and then gradually switched back in the dark become.
- dimming note that the lowering of the indicator tube voltage reduces the filament current becomes. If the voltage falls below a predetermined level this may require permanent heating of the filaments, thus the reduced energy flow through the heating current is compensated. Otherwise, there would be a risk of destruction the display tube or at least the impossibility of the Reignite.
- the ignition and lamp voltage of the different manufactured Pipe lengths of the display tube which result from the design and application, are determined by the choice of the appropriate one Ballast adapted to the need.
- the display tube according to the invention can be in various ways are operated: When the display tube is in continuous operation, the Coil electrodes preheated to ignition, then the heater switched off. This mode of operation is then preferably used Use when no high switching frequency is required e.g. e.g. in an advertising system that turns on in the evening and is turned off in the morning.
- the outer Shape is designed so that it can be installed in the display tube is.
