    Hello. I have a problem with replacing the R7S bulb in a lamp similar to this one floor lamp Everything is fixed. No screws that can be unscrewed. Only clamps that can not be loosened to remove the glass cover of the bulb. Attached photos. Maybe some of you have such a lamp and knows how to bite it.

    More and more things are glued and nobody cares that someone will someday want to undress. If you break, you'll buy a new one and that's what it's all about.

    Have you tried to unscrew the gland nuts?

    A gentle movement is left and you pull the glass up.

    This bulb has the same mounting system as the halogen filament.
    The terminal holders are elastic.

    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.

    As you endure until Wednesday, I will show you how it undresses in the photos.

    @ Łukasz-O I'll be strong :) I have no other choice.

    Added after 8 [hours] 26 [minutes]:

    And yet I could not stand it :) I tried to unscrew the second nut, but it turned out that these frames were Chinese plastic G and it broke. All in all it's better than a glass cover would break. It turned out that the clamps securing the shield were sealed on these frames and I would rather not be able to pull the cover up so that the clamps would let go. I will have to buy a new frame and replace the damaged one.
    A pair of Italian metal frames costs PLN 15 on Allegro. In bulk, probably half as much. And so the manufacturer of the lamp on something like that he saved by inserting Chinese plastic (reputable company yuanxin).

    I will ask for a visual instruction for replacing the filament - I have the same lamp as shown in the pictures
    thank you
  • Admin Elektroenergetyka
    The filament must be moved to the right or left (it is on springy contacts).
    You can help yourself with a screwdriver by sliding the cover in line with the red arrow in the drawing and pull it up through the cutout in the cover:

    OK thanks.
    And to get to the filament I have to take off the glass cover by tilting the upper clamps or is there another way?

    Take the cover off by pulling it up. If she does not want to come down, then she will move left and right.

    I did not want to force anything - thanks for the hint - the exchange turned out to be simple. Only I know from what the filament burned before - after installing the new one in the "on" position everything is ok but after turning off the "off" does not fade to the end and lightly pulsates - short circuit?

    Halogen or LED?

    R7S halogen - it is a lamp with dimming and brightening settings and in the "on" position it works correctly - while in the off position the halogen still shines and I have the impression that the light "vibrations" are delicate - the solution was to remove the plug from the contact and insert in case of using lamps but it lasted a few days and the filament burned out
