Inside a next generation shaped filament lamp (with schematic)

[@ockelboi9948]

I just have to come in with a warning here. WEAR GLASSES (like Clive does)! I too had the habit of misusing that exact type of pliers (a Plato copy). When i was nibbling away at a bit of plastic one of the shears (hope that is what i mean) broke off and hit my eye. I had to have quite complicated surgery and was blinded for weeks from blood in the eye. It is about ten years ago and my vision is almost as good as the other eye now but the pupil does not close as much and it is not round any more. I now use a standard side cutter that I have grinded down on the flat side to get the same kind of tool. Thank you from Sweden.

[@willusher3297]

I had the same failure - jaw snapped near the pivot and shot at me (thankfully only hitting me in the chest).

[@ockelboi9948]

Thank you for the engagement! I actually just tested another pair i have been afraid to use, and by only squeezing the handles a little harder than usual, and not cutting anything, it broke in the same way! We should urge our friend Clive to please do a video on this. And my modified standard side cutters I mentioned above are fantastic and so much more stable.

You know- Taking things to bits has always been something that I've felt at home doing... since childhood. In the past number of years, It's come about that my favorite tool for doing so when not much else will suffice, is a Dremel type tool with the itty bitty cut-off wheels in silicon carbide. My other favorite tool when nothing else will work is a diamond needle file... It will cut into anything, even hard ceramics and stuff, and will persuade stuff to break at that spot even if you don't cut all the way through it... and they can be had on the cheap.

[@bigblockelectra]

I went into a Lamps Plus a month ago. About 30% of the floor lamps, desk lamps, chandeliers, wall sconces, have unserviceable LEDs inside of them (the trendy modern looking designs mainly). The claim of energy savings comes out in the wash when you throw the entire unit away if the LED stops working. Thankfully they are pretty reliable, but it's an odd trade-off.

[@target844]

If you 3D print a holder for a filament-like that you can do that as a single part without so no gluing is required. Print the part so you can put the filament without it extending above the surface. Then pause the print, insert the filament, and resume the printing so the filament is completely enclosed. You can add a pause in the GCode. the simplest way to see how it is done is to look at tutorials for changing color in 3D printers without that capability built in. It might be a good idea to use a bit of glue to keep the filament in place so it do not move when the top part is printed

[@ProtonOne11]

You would need to do some trickery to accomplish that successfully tho. Definately not enough to only leave a section out in the model just big enough for the LED filament to fit. Your actual nozzle on the printer is wider than the bead of plastic it squirts out, so there needs to be a gap to give enough space for that. Second problem is, the slicer does not know where the LED filament is. So you need to tell it to never ever move the nozzle in a way that would collide with the LED filament, once it's placed in the print. The third issue i kinda see is temperature. PLA gets squirted out of the nozzle at over 200°C. I'm not sure this LED filament and the LED chips really like that heat treatment, as they will definately get some warm feelings while the printer keeps squirting plastic out nearby...

[@target844]

@@ProtonOne11 The idea was to create a channel the LED filament fit completely into. That way the nozzle can move anywhere on the next layer without hitting the filament. The limitation is that you can only have a filament on a single plane that gets embedded in the plastic but you could make it extend up or down by gluing some part. So the nozzle hitting the LED filament would not be a problem. The temperature might be a problem but the amount of plastic is quite low so it do not manage to heat up the surrounding parts a lot. The LED filament is also covered with silicone and it should be able to handle the temperature, It is used in socks that cover many print heads. The flexible circuit board and LED do survive the solder and melt at a similar temperature as PLA. I would guess that the LED filament has been exposed to a higher temperature during its manufacture than the PLA will ever heat it up to.

[@oilybrakes]

When I need to separate metal from plastic, I use a lighter. I heat the metal a bit and the plastic starts "creeping" which us perfect to slide the metal parts from the plastic without even deforming the plastic all that much. Usually, with a drop of glue you can stick it all back together without any obvious damages.

Hi Clive, next time you do a mains LED lamp teardown, could you try undervoltage testing? I'm in a part of Europe where the mains voltage dips to around 210V at peak times in the winter (lots of electric heating and cooking). At less than 215V, various LED bulbs in the house start to flicker..... very annoying.

[@chrishartley1210]

Rectified and smoothed mains at 210V input should give an output voltage of about 297V. You may well find that lamps with this type of linear controller avoids the flickering problem.

[@Northern5tar]

Now I feel really dumb. My kitchen light has been flickering this winter and I've been wondering why. Twas on colder days. Never put two and two together.

[@Torbjorn.Lindgren]

As he noted the box suggest they have 110-130V, 220-240V and 85-265V models ("universal") of this specific model.. Perhaps you should shop at say AliExpress instead of local supplies, many?/most? LED lamps on AE will either be available in universal models or are ONLY available as universal to save costs (since they're selling to both 115V and 230V markets they would otherwise need to stock both types). Usually "universale" means that the lowest voltage is somewhere in the 80-95V range, with relatively stable lumen output above that - the regulation is often not perfect, but certainly it won't flicker from it. The usual method of making dimmable LEDs require them to be fixed voltage rather than universal, but even there there's now universal voltage models. The circuit to do so usually involve a microcontroller, but these days a $0.02 one can easily figure out whether it's a leading or trailing edge dimmer and then locate the edge, derive a "dimming" percentage and then use that to drive the LED via a PWM DC source.

I really like the LED filament technology, it really simplifies the problem of running from mains voltage without the switching power supply and heavy heat sink, and avoiding the shadow of the big heat sink and power supply. So far I've had good results with them except for poor water sealing at the base sometimes ruining them in outdoor applications. "Suitable for wet locations" does not mean they will survive a hosing, but neither would the older LED's or CFL's.

Man that takes me back to my childhood. Dad and 4 of his brothers all owned farms very close to each other. Dad got the old home place, his brothers got parts of the farm land from grandfather who was the first owner of that very large area of North Dakota Prairie. They were the first owners after the land suffered the removal of the local native American's. The Home place, where I grew up was bult in 1910, the year of my fathers birth. One of his brothers got land that my grandfathers brother had began farming the next from us in distance built a large 2 story home to raise his 3 children on. That was built after the power lines were laid in so he had it wired for 110 volts, a very modern home where we without power learned the joy of television on visits to that farm. What interested me, perhaps even more then the television and that wonderful table lamp with pictures of jets and an inner shade driven from heat of the bulb that had clouds that seemed to make the jets fly was the kitchen light. In the center of that very large kitchen, a farm kitchen if you will was a circular florescent light. I spent long hours just looking at that light, trying to figure out how they bent that long bulb into a circle. I was very young at the time.

Single sided, but with phosphor density difference to get more even light.

Pretty bold of them to make the glass bulb so thin but have it be exactly the part people are going to grab and twist thinking it's plastic. Sounds like a recipie for increased bandaid sales

[@AnthonyZenrick]

I wouldn't mind seeing AC85-265V compared to, AC220-240V or AC 110-130V devices. I'm curious about similarities and differences. Is it just a change in resistors/capacitors, or a completely different board design, altogether?

[@bigclivedotcom]

For 120V it may be a different filament design or contain a simple voltage doubler to use the same filament.

A zero ohm for thermal isolation, I learned something today. Cheers!

Destruction the best part Clive thanks for taking us along AvE’s hammer made quick work of that

[@ytrew9717]

I thought the LED needed to be soldered on a heat think to dissipate the heat. Is that not a problem to enclose them in plastic?

[@bigclivedotcom]

It's spread over a large area.

[@kempshott]

Would they be dimmable (with a trailing-edge LED dimmer switch)?

[@bigclivedotcom]

The capacitor might mess that up.

Tips: If you wear a rubber glove for a nice grip and carefully twist the E27 base, it will easily come off !!!

[@ThePlacehole]

A question for clever people and/or circuit board designers: The led filament was surely attached to the PCB by hand, right? Soldering through-hole components is slow and annoying anyway, but having to thread and deal with long unwieldy lengths of wire on top of that is doubly so. Can't they just add like a "castelated edge" such that you could just bend the wires over the edge and solder without having to worry about the length or threading anything? Is that more expensive or something? It's not like the wires experience any mechanical loads or anything.

[@pauls5745]

is that filament a strip of 0402 's? I want to get some of those tiny leds

[@DrRChandra]

If the PF is so bad at only 0.5, what would be needed in the circuit to make the PF better? I would guess L somewhere, but how much and put where?

[@bigclivedotcom]

It's complex with electronic power supplies.

[@merpkerpie7267]

If I wanted to buy the light insert for those to make my own, what is it called? Any links would be appreciated too

[@bigclivedotcom]

Flexible LED filament. You can find them on aliexpress.

[@richardbriansmith8562]

Awesome big Clive

[@bbgun061]

Why would they make three versions, not two or just one universal voltage version?

[@alberttyong]

What would be good design wise is some form of ergonomic mechanical advantage to assist twisting.
