15. Itumanaho rigaragara (VLC)
LED irashobora kuzimya no kuzimya kuri frequence yihuta kuruta ijisho ryumuntu.Ubu buryo butagaragara kuri / kuzimya ubushobozi bufungura porogaramu nshya yo kumurika ibicuruzwa.LiFi (Ubudahemuka) ikoranabuhanga ryitabiriwe cyane mu nganda zitumanaho.Ikoresha urutonde rwa "ON" na "OFF" ya LED kugirango yohereze amakuru.Ugereranije na tekinoroji ya terefone igezweho ikoresha umurongo wa radiyo (urugero, Wi-Fi, IrDA, na Bluetooth), LiFi isezeranya inshuro igihumbi umurongo mugari hamwe n’umuvuduko mwinshi wohereza.LiFi ifatwa nkigikorwa cya IoT gishimishije kubera hose kumurika.Buri mucyo wa LED urashobora gukoreshwa nkibintu byiza byogutumanaho amakuru atagikoreshwa, mugihe cyose umushoferi wacyo ashoboye guhindura ibintu byinjira mubimenyetso bya digitale.
16. Itara rya DC
LED ni voltage nkeya, ibikoresho bigendanwa.Iyi kamere ituma amatara ya LED yifashisha amashanyarazi make yo gukwirakwiza amashanyarazi (DC).Hariho inyungu zihuse muri sisitemu ya DC microgrid ishobora gukora haba mu bwigenge cyangwa ifatanije na gride isanzwe yingirakamaro.Imiyoboro mito mito itanga intera nziza hamwe ningufu zishobora kongera ingufu (izuba, umuyaga, selile, nibindi).Imbaraga za DC zihari zikuraho ibikenerwa kurwego rwibikoresho bya AC-DC bihindura imbaraga zirimo gutakaza ingufu nyinshi kandi ni ingingo isanzwe yo kunanirwa muri sisitemu ya LED ikoreshwa na LED.Amatara maremare LED yamurika nayo atezimbere ubwigenge bwa bateri zishishwa cyangwa sisitemu yo kubika ingufu.Mugihe itumanaho rya IP rishingiye ku itumanaho rigenda ryiyongera, Imbaraga hejuru ya Ethernet (PoE) yagaragaye nkimbaraga za microgrid nkeya kugirango itange ingufu nke za DC hejuru yumurongo umwe utanga amakuru ya Ethernet.Amatara ya LED afite ibyiza bigaragara kugirango akoreshe imbaraga zo kwishyiriraho PoE.
17. Ubushyuhe bukonje
LED yamurika cyane mubushuhe bukonje.LED ihindura ingufu z'amashanyarazi imbaraga za optique ikoresheje inshinge za electroluminescence ikora mugihe diode ya semiconductor ibogamye mumashanyarazi.Ubu buryo bwo gutangira ntabwo bushingiye ku bushyuhe.Ubushyuhe buke bw’ibidukikije bworohereza ikwirakwizwa ry’ubushyuhe bw’imyanda ikomoka kuri LED bityo ikabasonera ubushyuhe bw’umuriro (kugabanya ingufu za optique ku bushyuhe bwo hejuru).Ibinyuranye, imikorere yubukonje nikibazo gikomeye kumatara ya fluorescent.Kugirango itara rya fluorescent ritangire ahantu hakonje harakenewe voltage ndende kugirango utangire amashanyarazi.Amatara ya Fluorescent nayo atakaza umubare munini wumucyo wagenwe mubushyuhe buri munsi yubukonje, mugihe amatara ya LED akora neza mugihe gikonje - ndetse kugeza kuri -50 ° C.Amatara ya LED rero akwiriye gukoreshwa muri firigo, firigo, ububiko bukonje, hamwe nibisabwa hanze.
