Do it yourself: Videoleuchte!

Do it yourself: video light!



Frage von Johannes:
Dezember 2005

Hello,

I have before me a build your own video light on. The structure s.sich is really very simple: Lamp, Battery, Switch.

I have kept an old lamp HAMA Combi fly about which I can use as a perfect frame. There, I would tuck 6Volt two lamps with 50W each.

Battery as I thought, I use a 6 Volt Battery scooter like this one:

http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=8019969520&fromMakeTrack=true

and connect it via a cable with the lamp. I can recharge it with my car battery charger.

This is all just theory until now ... Is it for me as I think? What problems might arise?

best regards, John



Antwort von Lothar:

Hello!
The cables should be thick enough to keep the resistance as low as possible. Moped Battery from a distance, I would take because of the acid contained therein. Look out for a rather cheap, at NC Accu, which is closed. Thus you run less risk that something happens. A car charger is, however, with security for the NC Accu not usable, due to high performance.

My pers Recommendation: 12 Volt and 12 Volt Battery Stahler own and are significantly better able to get anywhere.

Gruss
Lothar

Hi, clearly das Did I go with 12 V and a car battery made. Works wonderfully. Only the weight bothers. But it always comes out
s.was I know where to film.

Antwort von derTHOMMESisses:

Hi,

that is hot: 50 watts, 6 volts. Since flow quickly over 8 amps.

At 12 volts's are still just over 4 amps. Too much for NiCd Batteries. min in this case, you'd have to. 3 Battery packs connected in parallel in order to supply current to the battery pack is not too high, 4:3 = 1.33 amps - this is the maximum for NiCd cells in mono-continuous operation. The Anschaltstrom a bulb synonymous is much higher than the operating current. This means that when you turn flows to hire such a high current that ripped your battery pack. Well, it does not explode - but the Batteries go bad quickly.

S.besten suitable for such purposes are lead-acid batteries. The one can simply download (good - synonymous special power supply -) but not as expensive and are especially suitable for such flows.

The next election would be Lithium-Ion Batteries - Batteries for lighting but these are extremely expensive (> 300 EUR, 80 Wh) and need an expensive charger.

hope this helps.

Antwort von Johannes:

Thanks for all the answers

I think I will then use 12V lamps and a 12V sealed lead acid battery. Can this synonymous with a conventional car battery charger to charge or do I need for an extra charger?

best regards, John!



Antwort von Markus:

The lead-acid battery-You can load as a conventional lead-acid battery. A special charger is not to my knowledge is required. Incidentally, I have even two lead-acid battery in use and use a NiCd / NiMH / Pb-loaders.

Ne question would have fog lamps. These lights indeed limit the cone of light upwards, so do not be blinded motorists. Does not negatively as a movie light? What brands of fog lights would be as suitable?



Antwort von Peter S.:

You can turn the headlights, slightly upward tilt, vertical viewing ... or use a high beams. Previously gabs the universal set for a few dollars in any store. Today everyone wants to specially adapted Lights for exactly who his vehicle. On a junkyard, you will probably find s.ehesten.

Antwort von Andreas_Kiel:

Simply take a searchlight from the yachting sector. The 12 V and are synonymous to the H4 socket. Advantage: do not give a bruised by a lens or divided in half light, but a relatively circular beam of how you need it.
Big advantage: You can synonymous to 100W bulbs (not StVZO-approved) when put into it. But now it needs a bit more power :-)))
