Ano, ten soubeh už je kapacita, kterou prochází proud v řádech
desítek až stovek microA. A bílá LED už znatelně svítí při 20
microA.<br>
<br>
U těch LED světel to tak nevadí - naopak , máme v chodbě jednu
LED žárovku ( provedení s 140ks těch malých čipů) a "vypnutá"
svítí v noci tak akorát pro orientaci.<br>
Horší je, když je v žárovce měnič. Kondenzátor na vstupu se tímto
proudem pomalu nabíjí až dosáhne napětí, kdy se měnič spustí.<br>
LED problikne a okamžitě náboj kondíku spotřebuje. A celé se to
opakuje s cca 1-3 min. periodou . Ta závisí na kapacitě vodičů k
vypínači a kapacitě filtračního kondu v LED "žárovce".<br>
Stejně to dělají i "úsporky"....<br>
Taková "žárovka" v ložnici to je pak radost :-(<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Mame stojaci
lampu takova ta klasika se dvema halogenkami <br>
Nahore 250W asi s triakovou regulaci vykonu, na boku klasicka
40W halogenka 230V v G9 patici , bez regulace jen On/Off.,
neco jako toto<br>

<br>
Nedavno v bocnim svitidlu odesla G9 zarovka a pote co jsem v
okolnich Bau a jinych nakupacich nasel jen vyhypovane
halogenky v cenach bezmala 200Kc/ks. Jsemi poridil na ebay LED
5W G9 za nejakych 50Kc<br>
vypada takto.<br>

<br>
Vcera dorazila, sviti pekne, ale sviti porad :-)<br>
Pokud je vypinac v poloze On sviti jako 5W LED v porovnani s
puvodni 40W halogenkou sice trochu mene, ale ne o mnoho.<br>
Velke prekvapeni nastalo, pri prepnuti vypinace do polohy OFF,
misto zhasnuti se snizil jas, hrubym odhadem sviti jako 1W
LED, ale sviti porad.<br>
<br>
Zatim jsem to blize nezkoumal, ale vkradaji se dve otazky<br>
<br>
Kde udelali soudruzi z NDR chybu ?<br>
Chovaji se takto vsechny lampy tohoto typu?<br>
Pokud onen 1W tece i halogenkou zacina to byt energeticky
zajimave, zvlaste kdyz si toho clovek u halogenky nema sanci
vsimnout a v ramci uspor se zakazuji zarovky<br>
Muj odhad i toto svetlo spina triak nebo neco podobneho a
nekudy prosakuje radove 5mA.<br>
