Ib LED yog qhov hu ua "solid-state lighting" technology, los yog SSL. Yeej, es tsis txhob emitting teeb los ntawm lub tshuab nqus tsev (raws li nyob rau hauv lub incandescent noob ) lossis roj (raws li hauv CFL), SSL tawm teeb los ntawm ib qho ntawm cov teeb meem. Cov electrons zoo siab emit teeb raws li lawv ntws mus rau hauv qhov zoo them nqi.

Tom qab ntawd, ib tus tseem yuav nug, LED teeb ua los ntawm dab tsi?

Qhov tshwj xeeb semiconductors siv rau LED Kev tsim khoom yog gallium arsenide (GaAs), gallium phosphide (GaP), lossis gallium arsenide phosphide (GaAsP). Cov khoom siv hluav taws xob sib txawv sib txawv (hu ua substrates) thiab cov khoom sib txawv sib txawv ua rau muaj xim sib txawv teeb los ntawm LED.

Tom qab ntawd, lo lus nug yog, puas yog qhov muag teev LED muaj roj? Lwm hom lub teeb technology, xws li LED teeb , ua tsis yog muaj cov pa roj ; roj teeb qhov muag teev uas muaj txheej txheej txheej yog thawj hom uas muaj ib co form roj.

Tsis tas li ntawd, cov roj twg tau ntim rau hauv LED teeb?

Teb: Argon yog feem ntau siv roj siv rau puv lub teeb incandescent qhov muag teev . Nws nce noob lub neej los ntawm kev tiv thaiv cov tungsten filaments los ntawm deteriorating sai heev. Lwm yam cov pa xws li helium, neon, nitrogen thiab krypton kuj yog siv hauv teeb pom kev zoo

Lub teeb LED zoo li cas?

Cov xim nrov muaj rau LEDs yog "sov dawb" lossis "mos dawb," thiab "ci dawb." Sov dawb thiab mos dawb yuav tsim cov xim daj, ze rau incandescents, thaum qhov muag teev daim ntawv lo raws li ci dawb yuav tsim lub teeb dawb, ze rau nruab hnub thiab zoo sib xws qhov koj pom hauv khw muag khoom.
