Fluorescent LED Daylight

I decided to keep up with the times, and to save my money in the future, I decided to make some useful innovation. Or rather, to convert lamps with fluorescent lamps into lamps with LED lamps. The service life is high, the savings are great, and the cost is not much more expensive. Of course, you can buy it, but believe it is a little expensive to buy it, compared to the version made. Let's start. I first bought a 13-watt daylight lamp (you need 2 pieces) and about half a meter long.

Then I bought an LED strip. I did not just buy it, but I chose it for a long time, to be precise. LED strips a wide variety of electronics on the market: and color and white, and small and large. Choose your stop on the tape with natural light (not cold and not warm - pure white), with a power of 14 W per meter with a power of 12 volts. LED Ribbon
Here's the scheme:  LED Ribbon Scheme As you can see from the diagram, the LEDs are connected to 3 in the group. I will redesign this circuit in order to connect the LED strip to 230 volts of AC voltage without any expensive and unnecessary converters. We disassemble the lamp. disassembled luminaire

We see inside the pulse converter for the fluorescent lamp. We postpone it not far - we still need it. Now we need to make small calculations to calculate how many groups of LEDs we need for a 230-volt network. 230 volts after rectification turn into 250 V, or even more, there is such an effect of converting alternating voltage into constant. Take 250 volts and divide by 12 V (so kA is one section of threeLEDs powered by 12 volts), we get 20,8333. We always round up and take another section into the reserve, and we get 22, that is, 22 sections. In general, 66 LEDs will shine. The connection scheme is consistent:

I connected it like this: cut out pieces with scissors and solder with a wire, see pictures.

Next we need a dc rectifier, I made it from that same lamp. We take out the converter pulled out of the lamp and bite off the capacitor. Diodes with a capacitor are separate, so you just need to break the board in the appropriate place, there is almost no need to solder, except for the wires.
 AC to DC rectifier
Here is the scheme,if someone is not aware of what is at stake.

series-connected LED strip (of 22 sections) I got a length of about a meter. Naturally, in one luminaire this amount of light-emitting diodes is difficult to conclude - very narrow, and it is not necessary. Therefore, I bought two lamps, connected in series, in each one I pasted the LED strip in one row. Tape self-adhesive with a glutinous layer, but I advise in addition to miss superglue. Stuck together, assembled, connected.

I can not say anything about the minuses, but about the pros: It shines one and a half times better than the previous 13 watt lamp. Two lamps of daylight consumed 26 watts, and here two consume less than 10 watts. Durability, reliability. The biggest plus, in my opinion, is the direction of the glow: they almost never shine or blind in the side,but the table is excellent.
