• How to solder LEDs???

  • Brooke3987

Good afternoon. I need help with soldering 3W LEDs in such a way that if one fails, it doesn't affect the entire line. Maybe there will be a schematic? Please share your experience. I couldn't find anything on the forum, maybe I searched poorly. Thank you in advance.

You hang each LED on its own driver. Otherwise, it won't work.

So, 7 LEDs, 7 drivers? How do people make it so that a strip with, say, 30-40 LEDs doesn't fail?

Show me such a chain, I'm very curious to see it.

I haven't met, but I have some experience.

If a LED in the circuit fails, it can simply be temporarily shorted until there is an opportunity to replace it.

Yes, and about 130 volts come out of the circuit...

Ryan2281

Why suddenly? The maximum voltage on the drivers is 48V. It can power both a chain of 13 LEDs and a single LED. The drivers stabilize the current, which is the same whether it goes through a chain of LEDs or just one LED. In reality, I have 13 LEDs powered through one driver (red channel), while in the blue channel, there is one LED that operates from a separate driver. The power supply for the drivers is the same - 48V.

I have a controller like this: Input Voltage DC12V-DC24V Output constant current 350mA/color, and the controller is powered by a power supply similar to that for mobile phones. Will I be able to short it temporarily as you mentioned?

Amber6362

I don't know how to power this. If we consider the calculated drop on the chip of 3.2V, then the maximum is 128 volts on the circuit...

It is not suitable at all. This is a low-power controller for LED strips. How many LEDs need to be powered?

Corey3201

30-40 is not powered by anyone. Unless it's in some industrial developments.

Well, what was I saying?

7 stars, each star has 3 colors inside. The total power is 3 watts. I understand that each color is 1 watt.

Jason9952

The power of one star is 3 watts? What kind of stars are these?

Jesse

Edison. (only already soldered to the star) this is on the border of being taken away without documents... and I privatized a few for myself. They won't take them back. I want to make a 20L sea nanometer at the checkpoint. Colors: blue, red, green. Also, is it better to solder in series or parallel?

Angel628

Throw it away. Or assemble some toy. They are not suitable for an aquarium, and for the sea, they are 999% unsuitable - the spectrum is absolutely wrong. For the sea, you need LEDs from the Blue and Royal Blue series, mainly the latter. As for connecting, do it in series for each channel. Each channel goes to the corresponding channel of your controller. It will turn into a cool disco.

Come on, there is blue color there. And the little animal will be quite undemanding. I also saw a nano tank illuminated with blue and white LED strips with disco actiniae, and it looked fine. And here Pavel also illuminated it with a lamp that is not exactly for the sea, and it was fine too. Thank you.

I soldered each 1A driver like this. (I have 24 volts) The diodes have a working current of 340-360 mA. Of course, if one diode fails, all 6 in the string will stop working, and the current through the diodes will increase... but the diodes were chosen with a margin, and the heatsink with active cooling will prevent overheating, so there won't be a drastic increase in current... it will last until the repair.
