Definitions
- the invention relates to a gas discharge lamp with a translucent glass tube in which two electrodes are melted, in which the glass tube is mirrored over part of its circumference in the region of the discharge gap.
- Gas discharge lamps of this type are used in particular as flash tubes.
- Flash tubes are used, among other things, to generate light pulses for a light detector that triggers electrical switching processes, for example.
- the light from the flash tube can be directed to the light detector via a fiber optic.
- the flash tube should only emit light in the area opposite the input side of the glass fiber optics so that as much light as possible falls on this input side.
- the flash tube can be designed as a short-arc flash tube with a relatively small distance between the two electrodes and can be arranged in the focal point of a reflector.
- this arrangement requires laborious adjustment work.
- the object of the invention is to design a gas discharge lamp of the type mentioned at the outset, that is to say with a translucent glass tube, in such a way that the light is concentrated without additional external components.
- this object is achieved in that the glass tube is expanded in the region of the discharge path and the mirroring is applied in the form of a dome in the expanded region.
- the gas discharge lamp according to the invention is essentially designed as a glass tube, in which light bundling is nevertheless achieved in that the glass tube is expanded in the region of the discharge path and the mirroring is applied in a spherical shape in this extended region .
- the glass tube 1 of a flash tube is shown, in which two electrodes 2, 3 are arranged.
- the glass tube 1 is expanded in the area of the discharge path.
- a mirroring 4 is applied in the enlarged area 1 a, which bundles the emerging light 5, for example, on the input side of a glass fiber optic.
- the mirroring 4 is dome-shaped in accordance with the shape of the enlarged region 1a.
- the mirroring can be formed by a layer of shiny gold applied to the glass surface.
- a quartz rod can be melted into the glass tube 1 on the light exit side. With this quartz rod, a conventional, flexible light guide can be easily contacted.
- the mirroring Due to the mirroring there is an increase in the light output compared to a non-mirrored flash tube the exit area of 30% and more is reached. A complicated adjustment of the flash tube in a reflector is not necessary.
- the mirroring can be provided with a matt black, heat-resistant protective coating in order to ensure better heat radiation. Such a layer also protects the reflective coating on the outside of the glass tube 1 against mechanical damage, such as scratches.
- the invention is not limited to elongated tubes, but can also be applied to other tube shapes, such as ring tubes, U tubes and the like.
