A couple of questions about lighting (apartment) and the choice of lamps?

Question

Do it yourself

Hello. I wanted to redo the wiring at home, along with stretch ceilings with lighting.
When trying to dig a little deeper into the topic of lighting, a lot of questions appeared, therefore, I want to clarify a few.
What I want:
Lighting the apartment with energy-saving lamps, with the possibility of dimming (brightness adjustment).
There is a desire to dim through the "smart home", that is, to stretch all communications from each point to the control box (preferably one single box, and not a box in each room).
Difficulties:
As I understand it, fluorescent lamps are not dimmable in principle (more precisely, they are extremely lousy dimmable), so the choice fell on LED ones.
There is also a “trouble” with LEDs - everywhere there is either information that there are “special dimmable LED 220v lamps”, or how to dim an LED in vacuum.
Therefore, several questions arise:
Tell me, by what criteria to search for low-voltage lamps on the Internet, by what word, or at least a couple of links.
Tell me about low-voltage integrated solutions \ circuits \ howto (from a power supply unit to a light bulb) with dimming LED lamps
Tell me if there is something like an exhibition (or, as it’s fashionable: a studio) of lighting in Moscow - to walk around, look at lamps and systems in operation, in collection, flip switches to get ideas.
Besides LED lamps, are there any other economical lighting options that can be dimmed without much frills?

Answer 1

If you want to light up the apartment, invite a priest with a censer.

Answer 2

As an option: “dimming” by quantity - one lamp is on - one level of illumination, all lamps - another. Sometimes an additional minion light bulb is placed in energy-saving chandeliers, such as for night light mode - you can dim it.

Answer 3

As far as I know, all modern electric-saving lamps cannot be dimmed - they work hard in two modes - ON / OFF.
When I became interested in this issue, I realized that it would be easier for a night light to take, for example, spot diodes, shining somewhere unobtrusively in the corner - to go to the toilet at night and not step on a cat - it should be enough.

Answer 4

There are separate LEDs with dimming, but I have never seen so that there was an external control at once in a bunch.
Maybe then if you want full control where the control unit add a power source and dimming, respectively, and power the light bulbs not 220, but from this unit simply by turning off the built-in electronics?
Surely there are light bulbs that are easy to disassemble and solder the board with diodes directly to the base.
Another option is the easiest - it's trite to take all the same light bulbs with remote control. Due to the fact that they are the same, they will react to the remote control together and amicably. Surely there is a radio remote control, take a few and there is no crap with the setting.

Answer 5

I've also been looking for dimmable LED lamps for a long time.
And I did find it.
I can only recommend the place where I bought it (in St. Petersburg), because the lamps are a Chinese non-name.
In fact, these lamps turned out to be completely unusable, as they had a number of significant drawbacks.
1. The minimum brightness level was not zero at all, but very bright. What this is connected with is not clear. An ordinary incandescent lamp from the same dimmer turned off completely.
2. The glow had a clear stroboscopic effect. Apparently, the dimmer leaves only one half-wave from the change, and due to the low inertia of the LEDs, this pulsed voltage is noticeable to the eye.
3. The stroboscopic effect at some brightness levels was simply unrealistically annoying, the flicker frequency dropped by half (to 25 Hz). But this design of the dimmer is already to blame. Even an ordinary incandescent lamp at such levels flickered barely noticeable.
As a result, I spat and returned the incandescent lamps back.
Dimmer used Schneider Electric from the Unica series.

Answer 6

The problem with dimming and flickering with LEDs is that they are dimmed using PWM, hence the nasty flickering. Maybe, of course, in very expensive devices, the PWM frequencies are made significantly higher, but this definitely does not threaten Chinese rubbish, the electrician is simpler there. You can probably somehow try to soften the PWM using capacitances after the dimmer, but for me it’s not true.
FilimoniC, despite the fact that at the very least it is possible to solve the problem you set, I would not advise making the main lighting on LEDs. Balcony or closet - yes, but not the main rooms. It is in terms of comfort and vision. The best choice for me is halogens. Yes, expensive, not economical, but the coolest and most pleasant light in the room. Neither LEDs nor fluorescent lamps will give this.
Saving on electricity is killed by spending on good electronics and led lamps, what is sold for the most part is no good, if you do it for yourself, of course.

Answer 7

No, LEDs are normally dimmed by PWM. You just need the right frequency.
I have a dimmer for LED strips - no flicker, and there is the most PWM.
Yes, and power supplies for LEDs are dimmable, and there is also PWM, and they do not cost prohibitively, but quite normally, and they work perfectly.
Here we are talking, as I understand it, about ordinary dimmers, which were originally made for incandescent lamps.
There dimming is analog, there is no PWM there, the flicker is 50 or 25 Hz. And it is precisely because of this low frequency, and also because of the passage of one half-cycle from the sine, that flicker occurs.

Answer 8

I am also now dealing with a similar issue, I would like to ask the author of the topic, if he found a solution, then unsubscribe the results, or at least find out what details.
In the meantime, I’m writing what I dug up myself:
Energy-saving fluorescent lamps still come with dimming support, but you need to carefully look for them, or buy and test them, because. Not every manufacturer specifies this.
Here www.2700k.ru/product_info.php?products_id=119, for example, they clearly write that full dimming is supported (apparently from 0% to 100%) - I plan to order such and check whether this is really so.
I liked the dimmer more like this one: www.svetodom.ru/product/gusi-65253/ - it works great with halogen ones for me now.
But for the future, I still want to build something like a smart home, so I'll try to install the nooLite www.noo.com.by/sistema-noolite.html system - they have both dimmers and switches.

Answer 9

Dimmer lamps
work great with NooLite top question

Answer 10

I also recently ordered stretch ceilings and installed halogen bulbs, after three months the stretch ceiling melted in place of the bulbs, I had to change the ceiling, but then I installed LED bulbs and no problems, and I also advise you LED bulbs. The safety measures are detailed in the instruction manual very informative. And there you will find, by the way, how to arrange the lamps. Go ahead.

Answer 11

if you want good lighting in the room, you don’t need to fool around with chandeliers and lamps, just make stretch ceilings and evenly distribute the bulbs across the ceiling. We ordered the installation ( http://coplast.ru ) and the mother-in-law complained that our walls were dark and the rooms were dark, and now there is good lighting and everything is clear.
