Yes, it's a halogen lamp. Maybe with the removal of the filament itself I will have a problem, but for now I can not get to it at all.
I unscrewed these nuts on the sides, but it does not give anything, because the whole structure on which the bulb is attached consists of one U-shaped metal strip. It can not be moved apart. The only way to get into the bulb is after removing the cover. These nuts probably serve only to keep these openwork plates protecting against getting under cover of insects that could damage the filament.
The fixing of the glass cover is resilient and theoretically, if I bend one upper catch 90 degrees and the other a bit, the cover should release. It's just that after that I will not be able to bend the catch so that it will keep the cover. But the alternative is to buy a new lamp, so if there is no way out I will do it.
I found under the name the manufacturer of these lamps. There is assembly instructions
link but no disassembly anymore. And you can not remove the cover as the instruction requires it to be applied. Because you can push these lower hooks into the filament holder, but you can not take off anymore. I will write to them on Monday.
Is it possible that the manufacturer does not foresee the possibility of replacing the light bulb and it was a disposable equipment? RTV and household appliances manufacturers use different design tricks to make unprofitable repair, but that would be an inflection.
