Definitions
- the invention relates to a radiator module for use in a lamp housing having at least one discharge lamp located inside the module as a radiation source which emits a generated inside a discharge space by means of plasma UV radiation, wherein the plasma is formed by coupling an electromagnetic field in the discharge space and the radiation generated by the plasma along a predetermined optical axis through at least a first body transparent to UV radiation as a window, wherein in the plasma is provided at least one aperture with a through hole along the axis and along this axis generated by a temperature rays radiation penetrates through a second transparent body as an entrance window into the discharge space and exits through the first transparent body together with the UV radiation generated by the plasma along the axis.
- an electrodeless low-pressure discharge lamp in particular a deuterium lamp, which has a cylindrically symmetrical diaphragm body which in each case contains a cavity at its end faces.
- the two cavities are interconnected by a bore which serves as an aperture to constrict the plasma generated by coupling in a high-frequency electromagnetic field in the interior for the purpose of increasing the intensity of the emitted radiation.
- Both end faces of the cylindrically symmetrical diaphragm body are provided with a hermetic seal, of which at least one is formed as an exit window.
- the coupling of the electromagnetic field takes place capacitively by electrodes located on the end faces, which have at least one opening for the exit of the radiation, provided that they are arranged adjacent to an exit window.
- the diaphragm body has a through hole through both end sides along the optical axis with an opening guided in each case by one of the electrodes, wherein each of the openings is in each case arranged adjacent to a beam exit window.
- An additional radiation source is arranged along the beam axis, radiation of the additional radiation source also being guided through the diaphragm exit opening
- a plasma is formed by coupling a high-frequency electromagnetic field and radiation generated by the plasma exits the discharge vessel through a permeable at least for UV rays portion of the discharge vessel, wherein in the plasma is arranged at least one diaphragm body made of high temperature resistant material, the has at least one opening for constriction of the plasma region.
- the plasma region at least two apertures are provided in an optical axis, along which the radiation emerges, wherein for capacitive coupling of the electromagnetic field, the discharge vessel along the beam axis is provided at its ends with a planar electrode.
- at least one of the electrodes has an opening in the region of the axis of the radiation outlet, which is arranged adjacent to an UV rays permeable exit window.
- the object of the invention is to provide a simple and handy radiation source as a module that is suitable for a board structure with optical fiber coupling. Furthermore, the radiation source should be exchangeable in a relatively simple manner, wherein the exchanged module is correctly adjusted.
- a temperature radiator within the module along the optical axis in a predetermined position is arranged, wherein the module is inserted into a holder of the lamp housing with a coupling optics, and is locked within the holder by positive engagement of the module with respect to the coupling-optics in a predetermined position.
- a temperature radiator is provided as an additional source of radiation.
- the module for the purpose of locking in the region of its end face directed to the coupling optics on an annular adjustment element, which is immovably adjusted in relation to the first transparent body and the optical axis of the module in a defined position.
- the adjustment element engages in a recess of the holder for the coupling optics.
- an adjusting ring is provided as adjustment element, which is fixed by means of a screw in the recess.
- an incandescent lamp is used as an additional source of radiation.
- electrodes located outside the discharge space are provided, which however form a structural unit with the radiator module;
- the electrodes are arranged along the optical axis of the module, wherein they have recesses for the passage of rays in the region of the optical axis.
- the basic structure of such a discharge arrangement is known from the aforementioned DE 195 47 519 or US 5,814,951 or DE 195 47 813 C2.
- radiator module 1 has a hermetically sealed discharge space 2 with a quartz glass envelope 4, which contains three diaphragms 3 made of high-temperature-resistant material, such as molybdenum or tungsten, in its interior. wherein the apertures each have an opening 5 along an optical axis 6.
- electrodes 7, 8 are provided in the interior of the radiator module, which are separated by a dielectric (quartz glass) from the discharge space 2.
- a first transparent body 12 is visible along the optical axis 6 as a window permeable to UV radiation (quartz glass), through which the radiation generated as plasma within the openings 5 by means of electromagnetic excitation in the discharge space 2 emerges and into the recess 9 of the holder 11 the coupling optics 10 passes.
- the coupling optics 10 supplies a connected optical waveguide 23 (shown in broken lines) with radiation which emerges from the radiator module 1.
- the radiator module 1 has, along the optical axis 6, a further transparent body 13 as a second window (quartz glass), which divides the discharge space 2 from a space 15 for accommodating an incandescent lamp 16 as a thermal radiator.
- the transparent body 13 is permeable at least to visible radiation and infrared radiation, while the first transparent body 12 must also be transparent to UV radiation.
- the trained as a temperature radiator bulb 16 generates a spectrum that adjoins the UVA range and extends to the infrared range, while the UV radiation generated in the discharge space 2 has the spectral range of UV-A, UV-B and UV-C.
- the radiator module 1 has in the region of the coupling optics 10 a fixedly connected to the radiator module 1 circumferential ring 17, the position of which is adjusted with respect to the optical axis 6 and the subsequent coupling-optics 10 so that the radiation from the Incandescent lamp 16 and from the discharge space 2 on the way to coupling optics 10 is optimized so that they can enter into the optical waveguide 23 without major losses.
- the holder 11 is mounted on a printed circuit board 26, on which the associated electronics is housed.
- the holder 11 for the coupling optics 10 (according to Figure 1) with its recess 18 can be seen, in which the radiator module 1 is partially inserted so that the provided for adjustment circumferential ring 17 positively inserted into recess 18 and by means of a 3 recognizable screw 21 is locked in this position in the holder 11.
- Ring 17 is positioned relative to the rest of the radiator module 1 with the aid of a not visible in the radiator module 1 so that after insertion of the radiator module 1 in holder 11 is always an optimal adjustment of the lamp assembly is guaranteed.
- the holder 11 arranged on a printed circuit board 26 can be seen for arresting the emitter module 1.
- the incandescent lamp which is not recognizable here, is arranged fixedly in the lamp chamber 15 (FIG. 1) along the optical axis 6, the generated radiation also emerging along the axis 6 and passing through both the transparent body (quartz glass) of the discharge space formed as a window.
- the UV radiation generated by plasma spheres in the region of the apertures 5 (FIG. 1) also passes along the optical axis 6 through the first transparent body 12 (quartz glass window) into the coupling optics 10, from where they are refracted into one here shown optical waveguide 23 is guided.
