LED \u017eiarovka obsahuje viac ne\u017e len samotn\u00e9 LED di\u00f3dy. M\u00e1 tie\u017e elektronick\u00fd ovl\u00e1da\u010d, kondenz\u00e1tory, dosku plo\u0161n\u00fdch spojov, vodi\u010de a \u010fal\u0161ie komponenty.

Teplo je mimoriadne d\u00f4le\u017eit\u00e9. LED di\u00f3dy s\u00fa ove\u013ea \u00fa\u010dinnej\u0161ie ako klasick\u00e9 \u017eiarovky, ale st\u00e1le vytv\u00e1raj\u00fa teplo, ktor\u00e9 je potrebn\u00e9 odv\u00e1dza\u0165 z krytu. Ak je \u017eiarovka nain\u0161talovan\u00e1 v zle vetranom alebo uzavretom svietidle, teplota vo vn\u00fatri m\u00f4\u017ee by\u0165 ve\u013emi vysok\u00e1.

D\u00f4le\u017eit\u00fa \u00falohu zohr\u00e1va aj kvalita komponentov. Dve \u017eiarovky s rovnakou deklarovanou \u017eivotnos\u0165ou 20 000 hod\u00edn m\u00f4\u017eu ma\u0165 v re\u00e1lnych podmienkach v\u00fdrazne odli\u0161n\u00fa spo\u013eahlivos\u0165, ak pou\u017e\u00edvaj\u00fa r\u00f4zne ovl\u00e1da\u010de, kondenz\u00e1tory, LED di\u00f3dy a chladiace syst\u00e9my.<\/p>\n\n\n\n

St\u00e1va sa LED \u017eiarovka \u010dasom menej jasnou?<\/strong><\/h2>\n\n\n\n

LED di\u00f3da nemus\u00ed pri starnut\u00ed n\u00e1hle presta\u0165 fungova\u0165. V mnoh\u00fdch pr\u00edpadoch sa sveteln\u00fd tok postupne zni\u017euje.<\/p>\n\n\n\n

Tento proces sa ozna\u010duje ako pokles sveteln\u00e9ho toku<\/strong>. Ako LED di\u00f3da starne, produkuje menej svetla ne\u017e v \u010dase, ke\u010f bola nov\u00e1. Lampa m\u00f4\u017ee na\u010falej fungova\u0165, aj ke\u010f sa jej jas zn\u00ed\u017eil.<\/p>\n\n\n\n

Preto by sa deklarovan\u00e1 \u017eivotnos\u0165 LED v\u00fdrobku nemala v\u017edy ch\u00e1pa\u0165 ako presn\u00fd okamih, ke\u010f lampa prestane vyd\u00e1va\u0165 svetlo. V\u00fdrobcovia osvetlenia m\u00f4\u017eu ur\u010dova\u0165 \u017eivotnos\u0165 pod\u013ea toho, ako dobre si v\u00fdrobok zachov\u00e1va p\u00f4vodn\u00fd sveteln\u00fd tok.<\/p>\n\n\n\n

Modern\u00e9 LED \u017eiarovky si vo v\u0161eobecnosti dobre zachov\u00e1vaj\u00fa jas po\u010das tis\u00edcov hod\u00edn prev\u00e1dzky. V\u00fdrazn\u00fd pokles jasu u\u017e po kr\u00e1tkom \u010dase pou\u017e\u00edvania sk\u00f4r nazna\u010duje probl\u00e9m s v\u00fdrobkom, nadmern\u00e9 zahrievanie alebo in\u00e9 nepriazniv\u00e9 prev\u00e1dzkov\u00e9 podmienky.<\/p>\n\n\n\n

Pred \u00fapln\u00fdm zlyhan\u00edm m\u00f4\u017ee lampa vykazova\u0165 aj \u010fal\u0161ie pr\u00edznaky.

LED di\u00f3dy maj\u00fa aj v\u00fdznamn\u00fa v\u00fdhodu z h\u013eadiska spotreby energie. Na vytvorenie rovnak\u00e9ho mno\u017estva svetla potrebuje LED \u017eiarovka zvy\u010dajne ove\u013ea menej elektrickej energie ako klasick\u00e1 \u017eiarovka.

Za norm\u00e1lnych podmienok m\u00f4\u017ee kvalitn\u00e1 LED \u017eiarovka fungova\u0165 mnoho rokov.
