Mercury vapor halogen charge alarape

The invention is based on a Cxiooksilb gas discharge lamp, box in which, in addition to Queoxilbor and a Cdelgas, one or several halides, in particular iodido, are located in the discharge space. _o. Mercury vapor discharge lamps with the above

5oo Zusats of halides in 2ntladungsraura have been known for various Req * ⁰ turns. Depending on the intended purpose, halides ° verschiodenor Blemonto have been used. One has z.3. It was suggested to use the iodides of the elements gallium, thallium and indium in the discharge space in order to obtain absorption of the spectrum emitted by the lamps.

The Spoktralvorsoilung the emitted sound radiation is

naturally dependent on the Ilengon of the pre-Chiedonon elements in the discharge space and on their mutual relationships. (Daa Edolgas does not play a role in this context and is only used to facilitate the situation). The conditions can be adjusted in such a way that the opoctruni of the radiation emitted by the lamps is well preserved for a bootimmäo application, e.g. Boleuohtun ^.

POr many photoohemic processes and a small discharge lamp less geoignot, since large surfaces often have to be irradiated too much. This applies in particular to light-emitting procedures, but also to irradiation of uninterrupted fliosanic fluids in which ohenisoiie realizations must take place. There is an example in the plastics industry in the production of caprolactam, which is a starting material for the division of ITyion. For certain processes, lamps are even manufactured with a length exceeding an Ileter it is a Hoohdruok lamp · In these long lamps the discharge is naturally wall-stabilized.
