We make the lighting of the working area of ​​the table

In this article, we will consider how the author solved the problem of lighting the working area of ​​a sewing machine. As you know, the body of the sewing machine is located on top and obscures the work area. The master installed additional lighting on the case.

Tools and materials:
-Transformer;
-Rectifier;
-The wire;
-Fork;
-Switch;
-Soldering accessories;
-Drill;
-Fasteners;
-Screwdriver;
-LED Strip Light;






Step One: Transformer

A 220 V domestic network is supplied to the primary winding of the transformer. The secondary output is 12 V. The master connects the plug, switch and transformer to the circuit.














Step Two: Rectifier
The current at the transformer output is the same as on the primary winding i.e. variable, and for LEDs you need a constant. To solve this issue, the master, in the circuit between the transformer and the LED strip, installs a rectifier.










Step Three: Installation
The transformer and rectifier master fixes under the table cover. The wire from the output of the rectifier pulls up and connects to the LED strip. LED strip secures to housing








More details can be seen in the video below.

Sorry for the replay. I understand that the upgrade of the sewing machine has nothing to do with it smile

This, as I understand it, is about the advisability of using a current stabilizer to power LED strips.
Exactly. Tell us when appropriate. So be it, let me tell you. )) Indeed, there is such a case, but it does not apply to lighting the working field of the sewing machine.

All electrical engineering says that the current can be stabilized ONLY for a certain load. This load is CONSTANT and should not change.
I do not agree. Current stabilizers are designed to stabilize the current regardless of the load (within certain limits).
Quote: Nruter
Tapes of different lengths are designed for the same voltage, but for a DIFFERENT current, which depends on the number of LEDs in the tape, i.e. from its length. That is what Ivan Pohmelev is trying to convey to you.
I agree completely. True, there is a small subtlety, which, however, has no relation to the illumination of the working field of the machine.

Thank you, of course, but I am well aware of this. Question

That is, how to power the LED strip from the current stabilizer, refuse to answer?

Any. How is the stabilization current selected?

Basically, a resistor. And in general, open the Internet, or directories, but read for yourself.

There were tapes of the Russian brand Era.
Do you think they are not made in China? Which Russian Does it produce at the factory?
Quote: ya.fan2000
Well, then the current stabilizer is calculated for an arbitrary tape size.
How? Tell, at least in general terms.

Which current stabilizer? Transistor, or on LM-ke?

In some cases, this is when the LED strip is bought in China
Have you often met a tape made elsewhere?

In general, for the correct operation of the LED strip, you need a driver, or in other words, a current stabilizer.
How are you going to power a tape of arbitrary length from the current stabilizer?

For LED strips in some cases, you still need a current stabilizer.

For LEDs - yes, for LED strips - no.

To power LEDs or LED strips, you must use a current stabilizer.

Industrial? So they come with tables. Illumination, as near all machines - on the side is a lamp on a flexible "leg".

And my sister had three imported industrial cars and I didn’t see the light on any of them. I don’t remember the name. Maybe I just didn’t notice. I’ll ask you tomorrow.

After reviewing the article, I went to my daughter ... (She is fond of sewing with me. I gave her a good Swiss “Bernina-Burnetta”). I say, but to you, they say, the car’s body doesn’t block the light? ... She says: “And how can it close? The light is under the body!” ...)))) ...
I looked ... Yes, really ... The backlights are built in from below ... scratch
I say: "And in the old typewriter closed ???" She: "Also not! There is also a backlight from below. You can see for yourself" ...
Old in my basement. I looked ... Indeed - there is a backlight!)))) ...
Hmmm ... But there’s another pre-war Singer in my basement! Manual! Here ONLY THERE there is no regular backlight ...)))
P.S. Maybe it’s better for the master to change the car?))))
P.P.S. Oh, only the Ninnada that “the old ones will pull any fabric, but the new ones are tender” ... Maybe the nameless “Chinese” are tender ... And modern cars are even of the middle household class (Do not even need “Bernin.” The usual “Janome” , "Brother" and others like them ...) on the contrary, perfectly cope with any fabrics ...
(I studied the topic when I was choosing a gift for my daughter ... By the way, I was surprised that the household “Singer” is now considered the “bottom”)))

A machine made of steel
I came across a cast-iron!
Extremely slurred photos of the placement of LEDs and eyeliner
I agree, the placement of wires and LEDs on the elements of the thread tensioner is an extremely unsuccessful decision! smile

the master, in the circuit between the transformer and the LED strip, installs a rectifier
Not just a rectifier, but with a 12V voltage regulator! smile

According to the circuit breaker after the transformer, but in fact before it

1. The switch for some reason after a trance, and not before it. ((
2. There is no fuse. ((And the machine is made of steel.
3. Extremely slurred photos of the placement of LEDs and eyeliner. One can guess, but it would be better to place one or two normal snapshots of the LED part instead of pictures of a piece of wire, a switch and a soldering iron.
