4000 watt arc floodlight, or do-it-yourself artificial sun

Hello dear readers and the inhabitants of our site!
In this article, the author of the YouTube channel "KREOSAN" will tell you how he and his friends made a graphite arc searchlight with a capacity of about 4 kilowatts.

This homemade product is easy to manufacture, but requires safety precautions. Powerful Li-ion batteries are used to power it.

Materials
- Graphite contacts from a trolley bus
- Old satellite dish
- Mirror film ORACAL self-adhesive
- ShVVP wire 2 * 1,5.

Instruments, used by the author.
- 55 volt battery
- Terminals from the welding machine
- Power meter.

Manufacturing process.
So, the guys started making the main part of the spotlight from graphite contacts. They can be found at the end stations of trolley buses - they are simply thrown away as they wear out.



They also found a battery from an electric bicycle with an operating voltage of more than 50 volts.

The current will be measured with such a device. A pair of terminals from the welding machine were connected to the ends of the wires.


It is important that they use a wire coil as ballast in order to avoid a short circuit.

At the first attempts to ignite the arc, a power of about three kilowatts was obtained. And the resulting arc, in addition to very bright light, also produces very strong thermal radiation.





In the following attempts, it was possible to achieve a power of 4.5 kilowatts. The ends of the graphite bars do not cool down immediately.


It was decided to use a satellite dish glued with Oracal reflective film as a reflector.
And instead of the receiving head, graphite bars with a mixing handle were installed. It’s easier to adjust the distance between their ends, and to control the arc.






A powerful bright beam was obtained almost immediately. Focusing was no problem.





The edges of the electrodes practically do not burn, but they get very hot.


And thermal radiation is felt even at a great distance. You can see how the plasma escapes from the electrodes.





For night tests, the plate with the emitter was mounted on an electric bike. Instead of the headlights. Here is such a powerful beam.






Then a little ride around the night city.







Then they shone on high-rise buildings - the beam is well focused, and it shines even brighter than the sun.




These are the fun experiments the guys do.


Thanks to the author for the simple but extremely interesting idea of ​​a super-powerful flashlight!
All good mood, good luck, and interesting ideas!

I need such low beams
As a night lamp, too, will do! smile

This is worse than xenon. But also sharply cheaper.
I need such a low beam. )))
You asked
Are you sure that they are still working?
I replied that yes they work. And what rarity are they? It is a normal technique.
They work at the border. APM-90

APM-90 - floodlight installation, developed in the 1950s on the chassis of the ZIS-150. The principle of light generation is the electric arc combustion of a coal rod, incandescent lamp
Once again, the army is important result at all costs! smile
Such installations come to us on May 9
This year, the T-34, BM-13 Katyusha, Willis, and other rarities took place in parade! And we learned to shoot at the SA on the BM-13, because there were still a lot of them and shells for them, but expensive for new ones! smile
Are you sure that they are still working?

I am sure. Such installations come to us on May 9 from a neighboring military unit (although I met them elsewhere).
so there is also ultraviolet, and most likely hard, not? =)
and figure out the windows at night - nothing like that - "look out the window - I'll give you a hare"
gee

Are you sure that they are still working?
the first special teams equipped with floodlight technology appeared during the defense of Port Arthur during the Russo-Japanese War of 1904-1905 [1] [2].
The army has always been important result, at all costs! smile

1. The cyclist from behind the plate does not see ten meters (according to my estimates) the road in front of him;
2. Blinds oncoming drivers, creates an emergency;
3. The issue of efficiency is interesting.
thermal radiation felt even at a great distance
when welding with a carbon arc n = 0.5—0.65

They rode, and then rumors of a malfunctioning UFO passed through the night city, which flew low-low for a long time, looking for where to land.
