\"IMG_8920_web\"<\/a>N\u011bkdy koncem roku jsem na\u0161el na ebay LED diody ve form\u011b filamentu. Tyto modulky jsou pou\u017e\u00edv\u00e1ny v nov\u00fdch typech LED \u017e\u00e1rovek a maj\u00ed za \u00fakol vytv\u00e1\u0159et dojem, jako by v \u017e\u00e1rovce sv\u00edtilo vl\u00e1ko tak, jak jsme zvykl\u00ed. Nikde jsem nena\u0161el \u017e\u00e1dn\u00fd datasheet, ale cena byla tak n\u00edzk\u00e1, \u017ee jsem hned objednal 4 kusy na vyzkou\u0161en\u00ed. Z\u00e1silka dorazila v\u010dera a j\u00e1 cht\u011bl hned vyzkou\u0161et, jak\u00e9 d\u00e1vaj\u00ed sv\u011btlo. Bohu\u017eel jsem ale nebyl \u00fasp\u011b\u0161n\u00fd – prodejce uv\u00e1d\u00ed, \u017ee nap\u00e1jec\u00ed nap\u011bt\u00ed by se m\u011blo pohybovat mezi 50-60V, modul se v\u0161ak odm\u00edtal p\u0159i t\u011bchto nap\u011bt\u00edch rozsv\u00edtit. Po shl\u00e9dnut\u00ed n\u011bkolika vide\u00ed na Youtube <\/a>to vypadalo, \u017ee bude pot\u0159eba nap\u011bt\u00ed v\u011bt\u0161\u00ed – bohu\u017eel ale 60V byla horn\u00ed dosa\u017eiteln\u00e1 hranice m\u00e9ho laboratorn\u00edho zdroje. Dnes jsem si tedy p\u0159inesl mal\u00fd 12V olov\u011bn\u00fd akumul\u00e1tor, propojil ho do s\u00e9rie se zdrojem a v\u00fdsledek se dostavil<\/p>\n

p\u0159i cca 73V se prou\u017eek LED rozz\u00e1\u0159il. Obr\u00e1zek je po\u0159\u00edzen\u00fd ve tm\u011b, ve\u0161ker\u00e9 sv\u011btlo d\u00e1v\u00e1 pouze LED modul a podsv\u00edcen\u00ed displeje zdroje. Podle zdroje je proud modulem 9mA, p\u0159i\u010dem\u017e jmenovit\u00fd proud m\u016f\u017ee b\u00fdt a\u017e 15mA.<\/p>\n

P\u0159i pozorov\u00e1n\u00ed sv\u011btla jsem si v\u0161imnul jedn\u00e9 mali\u010dkosti a tou je r\u016fzn\u00e9 barevn\u00e9 pod\u00e1n\u00ed sv\u011btla, kter\u00e9 modul vyd\u00e1v\u00e1. Pokusil jsem se tento jev nafotit jak nejl\u00e9pe jsem dok\u00e1zal a snad to bude patrn\u00e9…<\/p>\n

\"IMG_8922_web\"<\/a><\/p>\n

Zat\u00edmco na jedn\u00e9 stran\u011b je sv\u011btlo do \u017eluta, tak na stran\u011b druh\u00e9 je studen\u011b b\u00edl\u00e9. Moduly jsem nakupoval ve verzi tepl\u00e9 b\u00edl\u00e9.<\/p>\n

Zkusil jsem i m\u011b\u0159it teplotu po n\u011bjak\u00e9m \u010dase, abych zjistil, jak moc se filament h\u0159eje, ale teplom\u011br ukazoval st\u00e1le teplotu kolem 20-ti stup\u0148\u016f Celsia, co\u017e je b\u011b\u017en\u00e1 teplota v m\u00e9 „pracovn\u011b“.<\/p>\n

Celkem m\u011b zklamala pot\u0159eba tak vysok\u00e9ho nap\u00e1jec\u00edho nap\u011bt\u00ed, tak\u017ee moduly pro pl\u00e1novanou pracovn\u00ed lampi\u010dku asi nevyu\u017eiji \ud83d\ude41 …<\/p>\n

Kdy\u017e se mi nepoda\u0159ilo napoprv\u00e9 filament rozsv\u00edtit, tak jsem napsal prodejci \u017e\u00e1dost o datasheet. Dnes p\u0159i\u0161la odpov\u011b\u010f s odkazem na dokumentaci, tak sem odkaz p\u0159ikl\u00e1d\u00e1m: http:\/\/www.z-light.com.cn\/d\/file\/product\/newseries\/dengsi\/20140217\/105lmZR39WWV5C21001.pdf<\/p>\n","protected":false},"excerpt":{"rendered":"
