Incandescent lamp

Many people want to pay less for light, including a light bulb. Now there are a lot of all kinds of economical lamps, but they are also not a penny. The cheapest: incandescent lamp. Here the design is cheap and reliable. I hope it comes in handy!

He returned home late a couple of days ago, without taking either a phone or a flashlight, and as if it turned out bad and a light in the stairwell, he tried to find the keyhole for about 10 minutes and then also inserted the key - he tried for about 5 minutes .. oh, that light. once a week it burns out stably .. and then I remembered what they do in the army in such cases .. They make a light bulb from an ordinary incandescent lamp =) a housekeeper, because it eats half the electricity and burns out not so often ..

And so, to create this miracle bulb we need:
• Ordinary incandescent lamp (I took on 100W)
• Nippers
• Diode (I used a Chinese-made diode)
• Soldering iron and soldering accessories


First, let's take a look at the scheme, which, in my opinion, is extremely simple to repeat.
Incandescent lamp

We take our incandescent lamp and solder the diode to it with the flow direction to the bulb.

Now we need to clean the base of the non-working light bulb from the glass, this must be done carefully and carefully so as not to get hurt.

Next, we take the base from the burnt out light bulb and heat the soldered contact on it with a soldering iron, as a result, a hole should form in which we pass the diode already soldered to the working light bulb.

Now we take our blank and put the base on the base and fix it with electrical tape or heat shrink.

We should get something similar to this:

Almost ready)

It remains only to trim the protruding end of the diode and solder it in the contact of the cap

Now done!

You can start testing, we screw our housekeeper into the cartridge and turn on the light

We see that the light is on in the floor and there is a certain flicker, but what else is needed for the entrance? This is enough for lighting. Now the bulb will last much longer and burns half as much electricity.

Thank you all and good luck!

As a joke, for fun, but how do they slip through the cores of transformers?

I already wrote in some comment that I’ve been racking my brains like alternating current (Sin, wave) through direct wires ...

I placed the diode in the switch itself. One wire in the switch was let through the diode (it doesn’t matter which wire to start) and everything worked perfectly.

Dmitry ... this is your "spotkach" at the very beginning)))). Sometimes it happens to me too - a trifle “I don’t think”, and then I don’t understand how this is possible .... And then it comes, and I wonder: “how am I?” Read carefully: You did not initially pay attention to the fact that PLUS and MINUS are completely different !!! This is not PHASE and ZERO !!! The diode is locked "against the plus" and not "against the phase." )))) It doesn’t matter if it is a phase, or zero - plus it happens at zero. As often as in the phase - 50 times per second !!!
And in your diagram, your arrows will confuse you !!! What makes you think that the ordered movement (current) of the particles starts in the phase, and moves to zero?)))) No-no !!! They "start" from the plus and fly off the minus !!! If at present the minus is on the neutral wire (let me remind you, the current is alternating !!!))))))), then they fly out of zero and go into phase!)))))
Both poles with alternating current do not differ in polarity. Just the one that all the power plants in the world stick into the earth is called zero !!!!

yes, it really works) although as a diode transmits a wave against the direction of the current, I still can’t catch up)) Well, okay, thanks, cool homemade)

Dmitrij,
Here Valery has already answered. Will work, no matter how and wherever you turn on this diode. Well, I add - you can check it experimentally (being careful, of course) ...

Dmitrij,
Will work in any version! Sorry for the banality, but the pluses and minuses here are swapped 50 times per second !!! And the phase, as rightly noted here, is just an ungrounded pole! On it, as well as on zero, they change places plus and minus the same way. And the diode just cuts one half-cycle !!! The spiral of the lamp, which has energy, simply does not have time to heat up to full heat, as it receives a "respite" ....

Well, just the same?

When sequentially turned on, it does not matter for the bulb in which direction the current goes and where the diode is turned on - before or after (the concept of "before" and "after" is generally purely conditional here). The bulb has no polarity. Moreover, it does not matter phasing. After all, what does a diode do? It misses half a wave from the network “sine”, no matter which half is “upper” or “lower”. Alternating current has no polarity. Phase and zero are relative to ground. But the light does not turn on between the ground and the phase.

Yes, it is a powerful diode. But how will it work at your zero or with the wrong polarity, I have no idea))

I have been using this scheme for drive lighting for a long time. A diode is needed with a reverse voltage of at least 300V. For a 100W bulb, the diode current is at least 250mA. I use old germanium diodes like D7ZH. The simplest thing is to include it in the circuit breaker circuit (I open the circuit breaker, disconnect the wire from any of its contacts, and the diode into the circuit break). The polarity of the inclusion of the diode does not matter at all, and also the place of its inclusion is phase, or zero. During operation, the diode heats up, but not much.

So this idea is a hundred years old at lunch ...))) The diode was always soldered by electricians in dark entrances, where the bulb never turned off - in order to save ... the bulbs themselves)))))).(Really no one remembers the fading dim light in an open lamp in the stairwell))))). The "universal USSR" diode - 226 was always used. Of course, it was soldered in the lamp in front of the cartridge, and more often, screwed on and wound up with electrical tape. And the light bulbs for a couple of years have always been enough ... And the phase - so after all, according to the rules, it connects to the central contact and is connected in the cartridge so that it does not rattle when you screw it in and use your finger to climb in)))))

Is it really possible for one such diode to withstand a load of 100 watts? Some kind of mysticism))


and the diode should only be in phase, otherwise it will not work.

Good day ! Isn’t it better to translate this idea into a wiring rather than a light bulb?
