It is rather amazing how far along LEDs have come for us to be able to slap a bunch down with a resistor on A/C and come up with a reasonable bulb.

[@daviddillon172]

I like the idea of usig the LED's as a bridge rectifier...new idea to me.

[@JasperJanssen]

Yeah, but each led is getting about 50V reverse voltage. That’s a heckuva lot.

[@PainterVierax]

@@JasperJanssen That's already the big reason why we never use Schottky diodes as bridge rectifiers for main voltage. Also it requires a translucent bulb and a clever physical placement of the diodes to smooth the 50/60 Hz flicker of such an led bridge (on top of the 100-120Hz flicker of the main led chain).

[@uwose]

@@JasperJanssen Not a problem. (1) The forward voltage of 39 LEDs ≈ 120V (blue: 3V each) becomes the backward voltage of 6 LEDs, so 20V/LED, not 50V. (2) With Z-Diode voltage of 20V, the breakthrough current is limited to at most (240-120-18)V/47kΩ = 2mA. Minus the forward current through the 39 LEDs. With orange LEDs you may have 2V per LED => 13V and < 3mA reverse current.

[@nrdesign1991]

Forming a bridge rectifier that way is deviously clever

[@paulturner5769]

The extra shimmering at 2:23 is probably because there is no phosphor with a brief fluorescence time to 'smooth out' the bursts of blue light.

I had been curious to know if using LEDs to make a full bridge rectifier was viable. I think this is the first time I've seen you take apart something using this. Nice to know it's viable. Whether it's practical remains to be discussed.

[@bigclivedotcom]

It's used in some industrial indicators, but only with a few LEDs.

[@mjkluck]

[@slmickysl]

[@phils4634]

A Very happy Christmas from all of us "Down Under" (where it is currently a very cosy 30C and 52% humidity with almost no surface level breeze!) Those would make excellent little outdoor ornamental lights. Being glass they would be resistant to Aussie sunshine, and there's plenty of environmentally - sealed E12 line sockets available from everywhere. Might be doing a spot of "Christmas Day" on-line shopping!

[@chrishartley1210]

I got some led bulbs the other day. Supposedly 12W, I was expecting from other experiences that they would actually be about 6W but they were a disappointing 3.3W. When I first tried them in my light fitting they were much brighter than the 3.3W would have suggested... for about 3 seconds before they failed. The whole circuit consisted of a MLCC capacitor with a discharge resistor and a bridge rectifier. My dimmer switch is a digital high frequency PWM type which meant that the capacitor passed much more current than normal which explained why the led filaments lasted about 3 seconds in the light fitting. So there's a word of warning to anyone with digital dimmers, don't use bulbs with capacitive dropper circuits.

[@theelmonk]

Does this include the dimmers recommended for leds, which have IGBTs instead of triacs to control the switch-off time instead of switch-on ?

[@chrishartley1210]

@theelmonk No. Digital dimmers turn the current on and off at high frequency. The effective resistance of a capacitive dropper is inversely proportional to the frequency. That effective resistance is calculated based on a frequency of 50 or 60 Hz. If the dimmer creates a higher frequency then the effective resistance is much lower, resulting in much more current being passed. IGBT dimmers still work on the basic 50/60Hz so they do not affect the effective resistance of the capacitive dropper.

[@ogonbio8145]

Me, someone who just watches these videos to see what the inside of stuff looks like: Ah yes, noted.

[@HerbaMachina]

don't all LED bulbs state their incandescent Wattage equivalent in light output on their packaging? Not usually their actual Bulb wattage.

[@chrishartley1210]

@@HerbaMachina Not on Aliexpress

[@pauljs75]

It's crazy how they find ways to further simplify stuff like that. But I'm wondering if there's still a possibility of sneaking a smoothing capacitor in there somehow. I think in some cases that flicker could still be noticeable.

[@StormBurnX]

Using the LEDs, which are diodes, as the diodes for a rectifier is wild. How have I never thought about that??

[@PainterVierax]

because it's very uncommon as the flicker and the current limitation is unsuitable for most applications.

[@StormBurnX]

@@PainterVierax That makes sense! I've heard of using LEDs as the current-reducing resistors in DC circuits - with a good bit of math it can be reasonably done, apparently. Just never thought about using them like that in an AC circuit!

[@PainterVierax]

@@StormBurnX I saw leds used like poorman's zener diodes to create some ghetto level shifters on transmission line circuits but it's not something advisable. As resistors circuit replacement, diodes in general are a bad choice as the semiconductor characteristics change with temperature and power.

[@StormBurnX]

@@PainterVierax Also LEDs can change characteristics depending on how much light they're exposed to, so I would definitely not rely on LEDs as level shifters. Still very creative! I love it

[@PainterVierax]

@@StormBurnX thx I didn't know that :) Another reason to be careful with alternative uses. The level shifter circuit is quite well documented on the V-usb website if you want to dig into this.

[@Damien.D]

I've used LEDs as bridge rectifier for AC indicator lights, years ago, still working as of today. But the current going trough it is minimal, maybe 10ish-mA

[@oscar_charlie]

The LEDs in the bridge rectifier are never reverse biased. When one side would be reverse biased, the other side conducts, limiting the reverse voltage to a reasonable value (15-ish volts for all 6), instead of the full 310V peak.

[@sundog486]

The increased shimmering of the blue one is the lack of phosphors. Phosphors alway introduce persistence to a greater or lesser degree.

[@phonotical]

It is great glass was used, was it me or was the Filament vibrating slightly while it was being powered, or is that an effect of the strobing . Be interesting to see the leds in slow motion, wee/see if the same positions light up at the same time for the ones acting as recritifiers

[@bigclivedotcom]

No vibration. Just LED rectifier shimmer.

[@ultratorrent]

Please demo doobying a whole string of these bulbs! I am curious about how much you could reduce the load on the resistors doing this.

[@jesuschal3802]

I’ve seen long flexible led strips like 5 or 10 meters long used in construction places. They are sold in reels like the ones used in cable extender reels. I wonder how the are built to keep all those leds lit without having a noticeable diminishing of the brightness along the run.

Interesting leds not supposed be reverse biased but, do handle 100v. Think depends on how the intrinsic layer is doped. Some pin diodes damaged if over reverse bias.

Clive, the reason the blue phosphor less LED shimmered was that the ones with phosphor had an afterglow that filled in the zero crossing dim spots. All of them would shimmer without phosphor. Merry Christmas. Hope you and Ralfie will share a hot toddy, to take the chill of the Irish Sea off.

[@TonyFisher-lo8hh]

Another angle on the "shimmer" is that the LEDs in the ”arms" of the bridge conduct at 50 Hz (half wave) while those in the "load" branch run at 100 Hz (full wave).

[@klausbrinck2137]

@@TonyFisher-lo8hh that´s what I thought too... (but I cannot judge linuxranch´s explanation, cause I don´t comprehend it)

@@TonyFisher-lo8hh yeah and without a proper placement of those half wave leds combined with the use of a transparent bulb, this 50-60Hz flicker is much more noticeable.
