Aj napriek tomu v\u0161ak m\u00f4\u017eeme tvrdi\u0165, \u017ee z h\u013eadiska vyspelosti LED nejde e\u0161te o fin\u00e1lne slovo \u010di dokonalos\u0165, respekt\u00edve vrav\u00edme o dlhoro\u010dnom, postupnom, av\u0161ak efekt\u00edvnom v\u00fdvoji. Jedno je v\u0161ak v s\u00fa\u010dasnosti u\u017e ist\u00e9, a t\u00fdm je fakt, \u017ee ide o ve\u013emi \u00fasporn\u00fd variant s pomerne \u0161irok\u00fdm spektrom vyu\u017eitia, \u010doho d\u00f4kazom s\u00fa tie\u017e led trubice ledprodukt.sk.   LED presnej\u0161ie zna\u010d\u00ed skratku anglick\u00e9ho Light Emitting Diode, \u010do prelo\u017e\u00edme prosto ako svetlo vy\u017earuj\u00faca di\u00f3da. Z\u00e1kladom osvetlenia je tak v tomto pr\u00edpade \u017eiariaca di\u00f3da, ktorej prev\u00e1dzka si v porovnan\u00ed so star\u0161\u00edmi mo\u017enos\u0165ami p\u00fdta len minim\u00e1lny odber elektriny, respekt\u00edve podobne ako je to v pr\u00edpade modern\u00fdch elektro spotrebi\u010dov. Z poh\u013eadu sveteln\u00fdch led produktov a sp\u00f4sobe ich \u017eiarenia tak vrav\u00edme o polovodi\u010dovej s\u00fa\u010diastke s prechodom P-N, ktor\u00e1 emituje svetlo.

V minulosti zasa napr\u00edklad vo forme r\u00f4znych blikaj\u00facich kontroliek.   K prioritn\u00fdm vlastnostiam LED di\u00f3dy sa tak nerad\u00ed len schopnos\u0165 \u00fasporn\u00e9ho \u017eiarenia, ale takisto dlh\u00e1 \u017eivotnos\u0165 a prakticky bezpochybn\u00fd neru\u0161en\u00fd chod. Charakteristick\u00e9 je tie\u017e okam\u017eit\u00e9 roz\u017eiarenie ihne\u010f po zapnut\u00ed.
