To date large number manufacturers are happy to offer their services for the purchase, selection and installation of high-quality lighting. LED lighting has characteristic advantages over conventional lighting, which makes it the most popular and necessary.

What types of LEDs are there? The first LEDs were semiconductor light-emitting crystals; to protect them from external influences - water, dust, mechanical shocks - they were covered with a regular housing with a translucent cover. The conclusions in them perform several functions:

connecting the light-emitting crystal to an electrical circuit;
mechanical fastening of the housing.

The connection was made by soldering on the reverse side printed circuit board by passing the lead wires through the holes in the board. It was necessary to drill holes, manually bend the leads with tweezers, insert them into the holes, bend it 30 - 45 degrees on the reverse side, cut it with side cutters, leaving 2 - 4 mm, solder the lead and the contact pad. It was labor-intensive work with little automation potential.

The situation changed with the creation of SMD-type housings. This abbreviation appeared with the frequent use of the English phrase “Surface Mounted Device”, which is translated into Russian as “devices for surface mounting”.

The SMD type housing also performs communication and protective functions. The pins in it are not wire pins to pass through the board, but several contact pads on the sides of the case. The case is glued with a drop of glue to the installation site so that the contacts on the case coincide with the pads on the board. Then the connections are soldered automatically or manually.

What SMD LEDs are used for lamps?

SMD cases are numbered, for example, SMD 1206 or SMD 5050. These numbers indicate the dimensions of the case in tenths of a millimeter. So the SMD 5050 LED housing has dimensions of 5.0 x 5.0 mm. Not all 25 square meters are used to accommodate LED crystals. mm of the case area, and approximately 20 - 22. Therefore, in such a case, engineers in the early 2000s managed to place three or even four light-emitting crystals and current-carrying elements. Thus, super-bright SMD 5050 LEDs white light, RGB, i.e. multicolor, as well as white RGBW type with four crystals - three color RGB crystals and one W crystal - white, from White.

A variation of the SMD 5060 case is the same SMD 5050 case, but only taking into account the thickness of the contacts on the sides of the case.

There are two more types of LEDs - SMD 3528 and SMD 2835. Both cases have the same overall dimensions - 2.8 x 3.5 mm, and a total area of 9.6 square meters. mm. But in the old ones SMD 3528 LEDs The light-emitting crystal has a round shape with a diameter of 2.4 mm, which corresponds to an emission area of 4.52 square meters. mm. In the new SMD 2835, the radiating element has dimensions of 3.0 x 2.3 mm and an area of 6.9 square meters. mm, which is 67% more. They also reduced the thickness of the phosphor, so the luminous flux increased.

New version of the housing in SMD 2835 LEDs made it possible to increase the area of contact pads by more than 2 times. This allows you to "shoot" more heat from the crystal, which means extending the service life or increasing the luminous flux.

Taking into account all of the above, the new SMD 2835 has tripled: luminous flux, rated operating current, power and direct current through the LED.

An example of a luminaire with these LEDs is an LED surface-mounted luminaire, model . High-brightness SMD 2835 LEDs with a total power of 6 W are used. Luminous flux 450 lm.

SMD LED 1206 It falls a little out of the general idea of marking SMD LED housings. It has a case measuring 3.2 x 1.5 mm. Operating current – 20 mA, brightness from 60 to 90 millicandelas.

I ordered these diodes back in December 2013. In February 2014 I already put it in place. I did the review. Since then the bathroom has been illuminated. None of them burned down. I decided to experiment a little with the lamp. At the same time, let me remind you of the diagram with calculations on the ballast capacitor. Due to the simplicity of their execution, these schemes are of most interest to ordinary people (and I count myself among them), not gifted with special design talent.
It is these drivers that people most often ask for advice on. Buy finished product easiest way. But assembling a lamp almost out of garbage is much more interesting. Moreover, there is a pleasant aftertaste in my soul from the fact that I managed to use something that had been lying around in a barn or garage for years :)
The parcel arrived quite quickly, a little over a month. It could be worse. Unfortunately, this product is at the moment unavailable. Time passes. Some stores disappear from the market, new ones appear. This store has sunk into oblivion.
LEDs were packaged in paper bag, covered with “pimply” polyethylene from the inside.

The seller is sociable, the parcel included thank you letter with a proposal for further cooperation. Even if it’s in English, it’s still nice.
I ordered “warm” LEDs and received exactly 500 pieces.
To make the lamp I used a classic “Chinese” design. The diodes are assembled in 4 parallels of 21 pcs. Total 84 pcs.

Soldering what I had in mind turned out to be a very tedious task. And if you don’t have a good soldering iron (soldering station), it’s just torment. I soldered as much as I could. When I did everything, I realized that not everything is so simple. A small nuance needs to be taken into account. When soldering, the diodes need to be slightly biased. Otherwise, they may block the tracks with their pad.

The soldering didn't turn out great. But this homemade product has a special place. This is my very first experience in designing LED lamps. Yes, it looks unsightly. But this is my story, and I will remember it.

This product shines at the level of a 75W incandescent lamp. This was enough for the bathroom.

At a network voltage of 230V, the power is 7.6W.

I have already seen from my own experience that homemade ones work much more reliably than purchased Chinese lamps. I didn’t do it for an exhibition, I was just experimenting. The board is double-sided fiberglass (from waste). Didn't poison anything. Just cut in in the right places grooves with a stub of a hacksaw blade. The rest of the parts are from old TVs. Only electrolyte and LEDs had to be purchased.

Everything was done hastily, for the sake of experimentation.

Nothing is more permanent than temporary.

Who said?..
And here is the formula used to calculate the capacitance of ballast capacitor C1:

Uts - the voltage drop on the LEDs is obtained by multiplying the number of LEDs in one parallel by 3V (21x3=63V).
Ic is the current that we expect to pass through the LEDs (but not more than permissible). Since there are 4 parallels, we multiply this value by 4.
Let's say we want to send a current of 10mA through the LEDs.
10mA*4=40mA.
Р= 0.04Ах63В=2.52 W - Calculated power of the panel.
Now let’s calculate the ballast capacity: using the first formula.
We get C1 = 0.76 μF.
Conclusion: with a ballast capacity of 0.82 μF, the panel will shine brighter than a 25-watt incandescent lamp
These LEDs allow current up to 30 mA (according to the seller). Theoretically, the power of the panel can be increased 3 times by changing the ballast capacity, but not forgetting about cooling.
The calculation is conditional, but it allows you to accurately calculate the lamp power.
I even checked. I measured the entire bunch of four capacitors with a multimeter. The device showed 2.254 µF.

Substituted it into formula (2). I got it:
Ic =(230-63)*2.254/3.18=118.5mA
P=118.5mA*63V=7464.8mW=7.46W
Taking into account losses on resistances and diodes, it turned out quite accurately.
The seller was most likely mistaken about 0.1W (LEDs). Wherever I look, everywhere - 0.2W. Yes, I changed a lot, everything works.
The lamp has good cooling due to its large area. After an hour of work, my hands are slightly warmer. After three years, not a single LED shows any signs of degradation. This is for the skeptics. Area 103 square.
Finally, we reached the bathroom. I'm doing renovations. This lamp no longer fits into my design vision :) So I took it off. I will definitely use it elsewhere. In the meantime, I decided to experiment (make fun).
But first, let me remind you about pulsations. According to smart books, pulsations above 300Hz do not affect overall visual performance. And here we have 100Hz all the time. We must take it into account. Therefore, we look at GOST R 54945-2012. There is a measurement diagram and a formula for calculation.

Then we look at sanitary standards (SNiP 23-05-95 NATURAL AND ARTIFICIAL LIGHTING).
The document is voluminous. It is very difficult to extract the necessary information from it. I'll help.
Depending on the purpose of the room, the maximum permissible pulsations are from 10 to 20%.

Russian lighting standards state that the depth of illumination pulsation in workplaces should not exceed 20%, and for some types of work 15 or even 10 percent. In fact, these are outdated indicators for comfortable work for the brain (the eye does not perceive the pulsation and there is a load on the brain - rapid fatigue and less productivity at the workplace) the pulsation should be no more than 4-5% in absolutely any workplace.

And this information is for fans of incandescent lamps. They also have pulsations. It all depends on the power.

25W incandescent lamps have the thinnest spiral. And it manages to cool down during the current transition through zero. Therefore, the pulsations are the largest (about 3%).
I didn’t consider lower power bulbs in principle. They are of little use in everyday life.
And this is already an “energy saving” 20W. It's a little worse here.

I got about 5%. But it is invested in the norms.
No, this is not a driver problem. This is a problem of the small filter capacitance of the capacitor in the rectifier. The new light bulbs have approximately the same picture, the pulsations do not exceed the norm.
Due to strong heating, cheap light bulbs quickly degrade their containers, turning the room into a laboratory for brain effects.
It's time to look at my homemade product.

I got 10% after three years of use. It's too good for a bathroom.
I also measured the capacity. I don't know how many were there initially. But there is 90uF left.

Let me move on to the actual experiment. I decided to change the circuit a little and see how it affects the ripples.

Circuit with half-wave voltage bifurcation :)
To smooth out the inrush current without affecting the operation of the circuit, I replaced the usual input resistance with an NTC thermistor. I did about them. The thermistor will protect the LEDs from contact bounce when they are turned on, as well as the switch itself from contact burnout when the lamp is turned on.

NTC thermistors have a very good property: as temperature increases, their resistance decreases. That is, at the initial moment they behave like ordinary resistance, decreasing their value as they warm up. I also filmed the characteristics.
