How to fix your low voltage LED Christmas lights

A brief exploration of three styles of wiring used in common low voltage light strings.
These circuits and repairs are only for the low voltage sets of lights that run from battery, solar, USB or plug in power supplies.
Note that for the two/three wire flashing/effects strings the circuitry is similar to the 3-wire strings, but with the LEDs alternating polarity along the string. If rejoining a damaged set then the incorrect polarity of the two LED wires will cause a colour change at that point in the string during flashing effects.
The difference in recording environment is a temporary thing due to catching covid right at the start of a short trip to Glasgow, that has turned into a much longer stay to comply with self isolation times.
I recovered quickly and the lat flow tests strip line faded fast, but I decided to play safe and extend my stay for as long as possible before travelling.

We use a similar strategy in hot water heating systems to balance pressure drop in piping; The top diagram would be called a "direct return" and the bottom diagram would be a "reverse return." Reverse return uses more piping but is easier to balance across many terminals and performs better when some terminals block or bypass flow.

100% off topic here, but your comment reminded me of our disaster of a hot water circulation system for instant hot water that was installed when we built our house...the plumber ran the PEX through the foundation uninsulated and our hot water heater never turned off due to all the heat being lost in the foundation. We had to just unplug the pump and now it's a longer wait for hot water than ever lol!

@@MrV1NC3N7V3G4 there's models now that only pump when they sense a faucet turned on or by push button, they only run until they sense the hot water at inlet. they're generally mounted under sink and pull from the hot pushing back down the cold pipe. there may be other wireless control systems now that will work with standard recirc setups, who knows.

@Smidge204 2 жыл бұрын

@@MrV1NC3N7V3G4 ooof! Always sleeve penetrations through concrete! What you can do to remedy this is a strategy called "demand recirculation." A small pump is put near the bathroom or wherever the hot water will be needed. Before you use the faucet/shower, press a button to activate the pump (some installs connect it to run with the light switch). The pump moves the water from the hot supply pipe back *into* the cold supply pipe, so the cold water is flowing backwards for a few seconds. Once the pump detects that the hot water has finally arrived it shuts off. The cold water may be a little warm for a bit, but the hot water is available right away and nothing goes down the drain. You can buy these systems as a kit that installs under the sink and uses the sink's hot and cold water taps, just need a GFCI outlet for power.

The gadget called "led keeper" works well for mains sets (at least in 120v land). It injects current and bites into the wire with a sharp point to let you "binary search" for the bad LED. No affiliation with them besides happy customer, their incandescent "light keeper" tool is also swell. Keep an eye out for them in after holiday clearance if you're curious but not presently in need. Turns out my main problem in my particular variety of outdoor set is with mainly the blue LEDs failing by a lead breaking off. The plastic caps break off the yellow/orange ones preferentially but they almost never fail, even when accidentally left up all year 😅

I just repaired a 2 wire set with 7 modes that had been cut by a lawnmower. I measured 28V AC on a multimeter. I found that most unusual for an LED string. But there was no DC component whatsoever. I was running low on time, so I didn't take the time to put it on an O-scope. It was a super simple repair. I soldered the wires back together and coated them with an ample amount of dielectric grease. Then 2 layers of heat shrink. 1 for each wire with the grease squeezed inside, and then another over the two together to strengthen the repair point.

@zero0ryn 2 жыл бұрын

We have a set of lights where there are 600 LEDs and they are colour changing. Each lamp can be ether warm white or a primary colour or both which gives a lovely pastel effect. You can also select fade from colour to white and back. They have 3 wires but as I can see strobing I suspect uses AC to select between white or primary colour. I tried shortening them with the result of only seeing the blue LED's light dimly. I reconnected the wires and hid the the 300 extra LED's under the sofa.

I’ve never seen it in strings, but most tape lights are sections of 4 LEDs in series, then the sections are in parallel. For long runs you can feed power from the middle or have a power supply at each end, also giving redundancy. Or for a price run a heavy gauge wire alongside and feed the power at several points. Edit: I’m referring to 12v dc tape lights.

@fonkbadonk5370 2 жыл бұрын

A question regarding this: I've been hesitant to start a project that involved ~10m long 5V LED strips (the individually adressable type, which sadly don't exist in 12V versions) because of the uneven brightness issue. I figured that feeding both ends would help this at least enough at those lengths, but would need to use two separate PSUs, one per end, and was not sure if that is a good idea. I would use the same types from the same brand, but were still unsure if this couldn't lead to some sort of issue. Is this a reasonable thing to do? (Running thick cables alongside would not be an option for this project, so also no feed in between.)

@AdityaMehendale 2 жыл бұрын

Clever 3-wire arrangement! If you put a ~10-ohm resistor as the "bridge" that you draw at 5:57 - this should be ok - better than just jumpering. I can imagine that most people don't carry a stock of 10ohm resistors and a soldering iron and a shrink-sleeve at X'mas, though...

@jlpicard001 Жыл бұрын

How did you determine that 10 ohms was enough to compensate?

@AdityaMehendale Жыл бұрын

@@jlpicard001 My guesstimate was based on eyeballing the gauge of wire that is snipped, and the length that needs to be bridged. However, a rough calculation goes like this: The USB-voltage is ~ 5V; The white-LED forward-drop is 3V. This leaves 2V across the "resistor". --> The round-trip-wire-resistance must then be 8 Ohm. BigCliveDotCom cuts the string halfway in the middle. The new string has half as many LEDs, so presumably needs only 125 mA in the new situation (for the same brightness of each LED). In the new situation, the remaining resistance is also halved - so 4 Ohm instead of 8. The forward-drop of the LEDs is still the same - 3V and USB_PB still delivers 5V. The new desired resistance is 2V/125mA --> 16Ohm (whereas the wire provides only 4) --> Add ~ 12 Ohm. :: 10 is almost 12 ;) especially with all other simplifying assumptions.. Hope this helps :)

@markfergerson2145 2 жыл бұрын

If you had no other option than to cut up a 3 wire set you could estimate the resistance of the part you had to cut off and insert a resistor with a close value to keep the total current at a safe value to keep from burning up the remaining LEDs.

For the less experienced among us: be sure to pay attention to the power dissipation and select the resistor(s) accordingly. A blazing hot resistor among nice and flammable christmas decorations is a nasty fire hazard. Derate the resistor too, as the power rating is for typical open air application on a PCB and not tucked away in some heat shrink tubing.

or just include a regulator for the lower voltage. mostly a simple LM7803 with a set-resistor for the voltage will do a fine job (and yes, it will get pretty warm if you took too much of the string off). If you just use a pot for the voltage-setting, you can slowly change the voltage up to the light you like or a bit less to have the remaining lights work longer.

I was somewhat inspired by you this year to make my own string of LED lights, I used colour changing LEDs each with a 180 ohm resistor and twisted together some 7/0.2 wire to wire them all in paralell. I 3D printed a little seperator so the LED wires wouldn't short when you heat-shrinked over the connections and resistor, then 3D printed some christmassy shapes that I glued over the LEDs to make them interesting. I was going to use your LED covers you put on a video ages ago, but in the end spent some time in OpenSCAD designing Christmas trees, parcels, snowmen and Christmas Sloths (long story!) instead. I only made 24 lights in the string but may well extend them for next year, although I only have a small room :D

@pd4689 Жыл бұрын

I've got a set similar to the diagram at 8:00, but every second LED is reverse polarity. The little controller board has different modes which changes the polarity of the voltage at different rates. If the Hz is fast it looks like they're all on, if it's slow, the light appears to 'walk' down the string.

@ManWithBeard1990 2 жыл бұрын

My best guess for how the ropelight could be made is that the light string would be blown through it with compressed air. It's also possible that the tube is extruded around it and the light string is fed through a hollow mandrel. I don't think they're feeding it through by hand. That'd be too fiddly I think.

I wonder if the tube is extruded around the LEDs afterwards? If the melting point of the LED wire insulation is higher than the plastic being extruded around them it would be possible to make infinite lengths. (regarding an earlier comment) I don't think they'd spend time threading a wire through the tube then pulling in LED strings, that would be very inefficient...

The Chinese do have extrusion machine that might do the extrusion process for the lights. I've seen pictures and specs on them.

One of the problems with C5 LED (cone style) Christmas lights here... squirrels bite the colored plastic bulbs off and bury them in the garden. They are very destructive, and the entire string is trashed because the wires will be bitten in half in many random places and 10 or more random bulbs will be bitten out of the string, and found weeks or months later scattered throughout the yard. I thought this was a bizarre situation until I read about it online and this is a problem lots of people experience (at least here in North America).

I bought a string of 50 coloured lights of the two-wire variety and have used them since to drape about my living room at the apposite time of year. They take 3 AA batteries and have two modes, flashing and continuous with an off position, and very fetching they are with their intense colours. The first time I used them (continuous mode) they turned themselves off after a few hours (I thought the batteries had gone flat) but, after fiddling with the switch, came on again, only to go off again hours later. It's apparent that they're meant to do this but there's nothing to indicate so on the box. Tonight, having noticed them come on at 10:18, I was coincidentally awake at 04:18 when they turned themselves off. Six hours fazackerly! How's it done? Happy New Year.

Many sets have the 6 hours on 18 hours off function. It can be annoying.

Probably only your channel provide a good explanation with diagram. Thanks for that Sir. If I may ask, my tumbler LED have 100 led's but half of them are dim and the half is bright. I already change the input main cable and try to replace the driver but have no luck. Do you have any suggestion to fix this? thanks in advanced

I love converting those battery powered lights to USB. I just get an old USB cable and solder it inside the battery box with some little resistor (choose resistance calculating on how much batteries the set requiers). You can even solder to the switch (if it has two positions) so you can choose between batteries and USB dynamically. This season I added USB feature to 3 of those sets

Hi Clive, I've always fixed my lights, mainly because I don't like the throw away society but also because I'm tight! I've never had problems before. Today I was fixing some multi colour cluster lights. Got them all working but had an issue with a RED LED. If I replaced it with a RED LED the other green or white LEDS in the string stopped work (depending on polarity of the LED). I tried a GREEN LED and they all work! I then tried a YELLOW & ORANGE LED and they behaved the same as the RED! I ended up sticking a PINK LED in & that worked!! I'm guessing something in the spec of those colours? Forward voltage perhaps?

@bigclivedotcom 2 жыл бұрын

Most modern strings use phosphor based LEDs for a uniform voltage. So the use of a traditional red LED will clamp the voltage too low for the others in parallel.

@@bigclivedotcom Thanks. I'll drop the supplier a line & see if they have that type. I just purchased 5mm of every colour! BTW, do you know of a supplier for the exact type used in most strings? I could only find a top hat version rather than the concave end as used from the factory.....

how did they get the string of lights inside the outer layer? there are many possibilities. it might have been a big fat outer layer that was heated to plasticity then pulled to length which shrunk it down with the led string inside it. it might have just been done like shrink tubing. all these clever ideas make modern living exciting.

I remember with the incandescent ones i had before that the first few were like fuses and if the bulb blew the whole set died.

@skylined5534 2 жыл бұрын

We had the sets with the fuse bulb. So long as that white tipped bulb is intact they should work. Something about a bypass in the normal bulbs should the filament fail but the fuse bulb didn't have that feature so if it blows the circuit is broken. I'm sure we also had another set that was like yours though and if one bulb blew the whole bloody lot went out!

I'm just guessing but I think that they get those strip LEDs into the plastic tubing by continuous extrusion. In other words the LED light strip is fed into the center of the extruder die and the plastic is extruded around it just like feeding of bare copper wire into an an extruder when putting on plastic insulation.
