104 LED filament lamp - just because....

What initially started as a rough rig to test some bulk LED filaments from Aliexpress, turned into an attempt at making a really big LED filament lamp.
It has to be said that side by side, the 12 filament Philips Dubai lamp appeared brighter at a similar power. So the Philips LEDs are definitely higher efficiency.
None of the filaments supplied in this batch were broken, there were a few that had clearly been weeded out in the factory, and they provided a few extra. The packaging was simple with the three strips of filaments on a piece of cardboard and wrapped with film. Antistatic packaging would be preferred, but they seem to have survived shipping well.
The listing I bought these LEDs from is:-
www.aliexpress.com/item/1005002258199411.html
The cost was £10 per set of 100 filaments, but that may go up if lots of orders are placed.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of RU-vid's advertising algorithms allowing it to be a bit more dangerous and naughty.

2:05 When I did the electronics module in A Level physics, whenever we had a test or an exam, often, one of the questions was to draw a bridge rectifier, but I could never remember which way round the diodes went, so I always had to work it out in my head as I drew it. If only someone had said "all the diodes point to positive." It's obvious too, when you think about it.

the way I do it is, draw the diamond with caps in the place of the diodes, then simply turn the caps into diodes. I do this quite often when I am not sure which way to put the diode, draw it as a cap, think about it and convert to diode.

I really, really like those filament style LEDs. Years ago I bought several bulbs that used those and were about as close as you can get to an early 1900's style bulb while still having useful light, which I absolutely adore. I know there are others that look even closer to the original bulbs, but those are purely for show that give off next to no light. Not that that's a bad thing, of course. But I prefer them being functional as well as visually appealing.

I also love the Edison bulb for LED lighting because you get the aesthetic dialect of incandescent with the energy savings of LED. And, you can bet that Thomas Edison could scarcely have imagined that we could turn his light bulbs any color of the rainbow using the power of the internet. Also, I read about a new LED fabrication process that produces a CRI of 98+, making it the closest thing LED has yet become to natural daylight or incandescent light.

A couple of years ago on Amazon I accidentally bought a Maglite Solitaire penlight that used an incandescent bulb instead of a LED cob. It was so dim that I thought I'd been scammed! But yeah, it turns out that there's a market for really dim lights. In the case of my little Solitaire it turned out to be for aviators and campers. In those fields, it's beneficial to have a dim light by which you can read maps and manuals without disrupting your night vision.

@AndrewGillard
@AndrewGillard 2 года назад
Instead of a "super long _lasting"_ lamp, how about a _super long_ lamp‽ 👀 Connect all 100 filaments in series! It'd be like a fluorescent lamp! Or an LED strip! But instead of being powered by _boring_ 12V, 24V, 120V, or 240V, it'd require a _far more interesting_ 4~5 kV! (According to my sleep-deprived calculations, anyway 😴) Can the FART transformer output voltage get that high at enough mA? I don't recall its specs 🤔 (I only managed 3 hours of sleep last night, so after feeling like a zombie all day … _this_ … is apparently what my brain comes up with while I'm barely still conscious 😶 🤷‍♀️) _Don't play with high voltage, kids!_

@blower1
@blower1 2 года назад
Tying more banks in series so combined their forward voltage is closer to the rectified mains voltage and using a linear current regulator design, or just a resistor, will get you a much better power factor - although you will have to live with the slight mains flicker as dc smoothing cap will kill the power factor.

You need to plug an electric kettle into the mains, then have the steam from the kettle fed into a small turbine that turns a generator that powers the circuit. That'll bring your power factor to 1.

@johndododoe1411
@johndododoe1411 2 года назад
110 has the advantage of being the international and memorable value from the traditional set of 55/110/220 . 55 V is appropriate for arc-lamps (19th century). 110V and 220V are the doubled values chosen as standards when the electrical grids were built. 230 and 115 seem to be fallout from the idiotic attempt to create an EU compromise between 220V grids in the rest of the EU and the unusual 240V grid in the UK. The only nice thing about 230V is that the 3-phase version is a round 400V instead of the traditional 380V.

I rememberin the good ol' days before mains-powered LED lamps were affordable, my dad made his own. He usually kept the bases and electronics from failed CFL lamps, and would use the bridge rectifier and smoothing capacitor on those tiny CFL driver boards to make a 168VDC supply, which he would then connect to a set of 5mm white LEDS. Unfortunately, the super-cheap 5mm white LEDs didn't last long, and the homemade LED lamps would lose brightness pretty fast. He got tired of swapping out LEDS, commercial ones are now affordable and relatively reliable, so the homemade ones are sitting in the shop pile somewhere. I should see if I can get Dad some LED filaments to play with, he could make some fun 3D printed novelty lamps....

Sometimes, I feel like BigClive is ElectroBoom but slightly more careful with live wires :D

As you know, LEDs are often dimmed using a PWM controller. It's easier (cheaper) to control block wave frequencies with electronics than controlling current directly. But then I wondered if it's possible to smooth this PWM flickering. Using a capacitor doesn't help, as it negates that PWM functionality (the cap will just charge to the maximum voltage, and provide any current the LEDs want or the system can offer). Apparently, this is possible using an inductor in series with the load. But I don't really understand the principle. Could you make a video about this? Or do you already have a video about it. Specifically: how do you select an inductor, does it depend on the voltage or the wanted current?

It is good to see someone that can casually do this. As an electrician it makes me giggle. I di this all the time 🤣

Philips have released an LED 'HPL" series of LED filament lamps designed to replace lower wattage MBF. I picked up an 18w lamp which is designed to replace an 80w and it's quite impressive at 3000lm!

I'm picturing a massive Big Clive logo light made with hundreds of these filament LEDs

Interesting! I've seen LED bulbs with similar shaped filaments yet the bulb is advertised to consume ~ 5 watts. Certainly these look easier to use if you want to wire them to a mains voltage for cheap

It's nice to see how small your power supply is. Useful for projects with limited space. Imagine if 12V 50W or 100W would be somehow that small.
