Rozeznat z\u00e1vity E14 a E27 nen\u00ed a\u017e tak slo\u017eit\u00e9. \u010ctrn\u00e1ctka je men\u0161\u00ed, u\u017e\u0161\u00ed a obvykle b\u00fdv\u00e1 u \u017e\u00e1rovek s men\u0161\u00edm p\u0159\u00edkonem. LED \u017e\u00e1rovky E27<\/a> <\/strong>jsou ov\u0161em b\u011b\u017en\u011bj\u0161\u00ed. Pokud \u017e\u00e1rovku vym\u011b\u0148ujete, vezm\u011bte si tu starou s sebou do obchodu, jestli m\u00e1te \u00fapln\u011b nov\u00e9 sv\u00edtidlo, p\u0159e\u010dt\u011bte si specifikaci na krabici.<\/p>\n

 <\/p>\n

S paticemi to funguje podobn\u011b \u2013 u bodovek se zpravidla setk\u00e1te s patic\u00ed G4 (pro nap\u011bt\u00ed 12 V) a GU10 (klasick\u00e9 nap\u011bt\u00ed 230 V), \u017e\u00e1rovky s R7S se pou\u017e\u00edvaj\u00ed v reflektorech a m\u00edsto halogenov\u00fdch \u017e\u00e1rovek, MR16 (n\u011bkdy ozna\u010dov\u00e1na GU5,3) je patice \u017e\u00e1rovek, kter\u00e9 jsou vhodn\u00e9 i do sprchov\u00fdch kout\u016f. Ale co d\u00e1l sledovat?<\/p>\n

<\/div>\n
<\/div>\n

Kolik kelvin\u016f pot\u0159ebujete?<\/strong><\/p>\n

Kelvin je jednotkou ud\u00e1vaj\u00edc\u00ed barvu sv\u011btla. \u010c\u00edm je hodnota ni\u017e\u0161\u00ed, t\u00edm je odst\u00edn \u017e\u00e1rovky teplej\u0161\u00ed. Tepl\u00e1 b\u00edl\u00e1 barva<\/a> <\/strong>s na\u017eloutl\u00fdm a\u017e naoran\u017eov\u011bl\u00fdm odst\u00ednem m\u00e1 cca 2800-3300 kelvin\u016f. U studen\u00e9 se hodnoty pohybuj\u00ed mezi 7000 a 8000. Volit byste m\u011bli prost\u011b podle toho, co je v\u00e1m p\u0159\u00edjemn\u011bj\u0161\u00ed. Obecn\u011b se ale doporu\u010duje volit teplej\u0161\u00ed odst\u00edny do ob\u00fdvac\u00edho pokoje a lo\u017enice, kde se chcete c\u00edtit p\u0159\u00edjemn\u011b a pohodln\u011b. Studen\u00e1 b\u00edl\u00e1<\/a><\/strong> se hod\u00ed t\u0159eba do koupelny, kuchyn\u011b, na toaletu \u010di do pracovny \u2013 nebude v\u00e1s tolik usp\u00e1vat.<\/p>\n

 <\/p>\n

Mimochodem mo\u017en\u00e1 v\u00e1m bude p\u0159ipadat, \u017ee ani tepl\u00e1 LED \u017e\u00e1rovka nen\u00ed tolik \u017elut\u00e1 jako va\u0161e p\u0159edchoz\u00ed klasick\u00e1 \u017e\u00e1rovka. Je to v\u0161ak z\u00e1m\u011br. \u017dlut\u00e9 zabarven\u00ed nen\u00ed pro o\u010di moc dobr\u00e9, a tak to s n\u00edm v\u00fdrobci v sou\u010dasn\u00e9 dob\u011b p\u0159\u00edli\u0161 nep\u0159eh\u00e1n\u00ed.<\/p>\n

 <\/p>\n

Z \u010deho vyb\u00edrat?<\/strong><\/p>\n

Pokud se rozhodnete pro tyto modern\u00ed vychyt\u00e1vky, je mo\u017en\u00e9 zakoupit nejr\u016fzn\u011bj\u0161\u00ed typy, jako jsou stm\u00edvateln\u00e1 LED \u017e\u00e1rovka<\/strong><\/a> a LED z\u00e1\u0159ivky<\/a><\/strong>. Beze sporu nab\u00edzej\u00ed velkou v\u00fdkonnost, \u00fasporu a \u017eivotnost. Kl\u00ed\u010dem k \u00fasp\u011bchu je ni\u017e\u0161\u00ed spot\u0159eba elektrick\u00e9 energie.<\/p>\n

Pohl\u00eddejte si i lumeny<\/strong><\/p>\n

Aby t\u011bch jednotek nebylo m\u00e1lo, je pot\u0159eba LED \u017e\u00e1rovky<\/a><\/strong> rozezn\u00e1vat je\u0161t\u011b podle lumen\u016f. Lumeny (lm) ozna\u010duj\u00ed sv\u011bteln\u00fd tok, tedy sv\u00edtivost. \u010c\u00edm je lumen\u016f v\u00edce, t\u00edm je v\u011bt\u0161\u00ed. U klasick\u00fdch \u017e\u00e1rovek se v\u00fdkon posuzoval podle watt\u016f, p\u0159i\u010dem\u017e 25 W u klasick\u00e9 \u017e\u00e1rovky odpov\u00edd\u00e1 LEDka s hodnotou 200 lm. 40 W se rovn\u00e1 400 lm, k 60 W je ekvivalentem 700 lm.<\/p>\n

 <\/p>\n

Co d\u00e1l je\u0161t\u011b sledovat?<\/strong><\/p>\n

O nap\u011bt\u00ed se zmi\u0148ovat nebudeme, v\u011bt\u0161ina \u017e\u00e1rovek na \u010desk\u00e9m trhu je ur\u010den\u00e1 na standardn\u00ed nap\u011bt\u00ed v rozvodn\u00e9 s\u00edti (230 V 50 Hz AC). Zaj\u00edmav\u00e1 by pro v\u00e1s ale mohla b\u00fdt t\u0159\u00edda kryt\u00ed ozna\u010duj\u00edc\u00ed odolnost proti vod\u011b a vniknut\u00ed ciz\u00edch t\u011bles. Do koupelen pot\u0159ebujete t\u0159\u00eddu IP44. A na posledn\u00edm m\u00edst\u011b je pot\u0159eba pouk\u00e1zat rovn\u011b\u017e na vzhled. \u017d\u00e1rovka m\u016f\u017ee m\u00edt klasick\u00fd tvar, vypadat jako spir\u00e1la, sehnat se daj\u00ed i retro filament \u017e\u00e1rovky<\/a>.<\/strong> Z\u00e1le\u017e\u00ed jen na v\u00e1s, co by se v\u00e1m l\u00edbilo.<\/p>\n
