Led rasvjeta

[pharaoh]

eh ovako problem + pitanje, kupio sam GU 10 žarulje za ugradbenu rasvjetu slika priložena, i to GU10 ali sa ledicama, svjetle duplo slabije od GU10 halogenki ali ne griju (da ne kažem ove halogene peku) i troše 50 puta manje struje (GU10 halogena 50W- GU10 led 1,5 W), i da na 220 V, eh ali stvar je u tome što kada na prekidaču prekinem struju one još uvijek slabo svijetle????
što se događa, zašto ih nemogu potpuno ugasiti???

koliko dugo jos svijetle?

pad napona...mah pa to za lokale...

koliko dugo jos svijetle?

non stop, svijetle puno slabije ali svijetle, jedna mi je ravno iznad glave, katastrofa.

Evo bar se uklapa u SOS live earth uštedu energije, sam da još skužim kak da ju sasvim ugasim i ja prezadovoljan.

evo pogledajte ovo


led gu10, Halogen: Hochvolt LED Leuchtmittel 230 Volt, GU10, 20 LEDs, orange - gu10 led / Gu 10


i da jedna žarulja je 50 kuna


ili


Fit for Mobile - LED STRAHLER - GU 10 - 20 LED`S - 5 WATT 230 VOLT WEISS

neš sam našo al ne kužim.

"I have installed a number of the BC22 24 LED globes to replace incandescent globes.
When the light switch is off I note that the LEDs still glow very dimly.

We suspect it may be because the wiring in your house uses positive wiring for the switching.
This came to us from a very knowledgeable customer and we think he's on to something.
With a large voltage applied and such a low current draw, it does not take much capacitance to earth for a small current to flow.
Its enough to light the lamp dimly.
Switching the neutral results in a large active-earth potential existing all the time
Switching the active results in only a neutral-earth potential being present, which is usually in the order of a couple of volts.
Even in the worst of installations it's never much more than about 15volts, not high enough for the capacitance to earth to cause a current to flow that will break the threshold required to light the LED....
Previously we were implying an effect similar to phosphorescence, where things like TV picture tubes remain luminous after being switched off - but there is no electron flow as such.


Will this affect the life expectancy of the globes

Honestly can't say - the mA reading isn't enough to fry anything nor is the internal transformer under any duress.
I'd have to say that it wouldn't affect the lifetime of the bulb which under normal circumstances should be 10 years or so.
Its your city mains power that kills all appliances, bulbs and everything else in the end.
If you have good gear think of UPS protection on stereos. lighting circuits etc"

možda prekidač ne valja

[Vuxs]

ma kakav prekidač..ti veli čovjek da kao kod tv-a (s tubom) kad ga ugasiš josh se vidi svijetlo a neide struja..to ostane naboja u elektronima....
mah nije to neki veliki problem..

[pharaoh]

pa to i ja kažem , nieje ozbiljan problem jedino što me smeta jer mi je jedna iznad glave iznad kreveta gdje spavam.


inače informacija o uštedi energije, ušteda je 92 %

[skin2yard]

kako sam ja iz ovog skuzio, led lampa ti svijetli upravo zato sto ne zahtjeva puno dotoka struje, znaci i kadprekines strujni krug, valjda jos uvijek tece mala kolicina struje koja je dovoljno jaka da bi led lampa svijetlila

[Vuxs]

bravooooo....al opet ak stalno svijetle možda je problem u prekidaču,egipčane jesi probao prekidač je vruch??on ziher malo serucka..
