"Xa kuthelekiswa nezibane zemveli kunye nezibane zokugcina amandla, iimpawu ze-LED zinokubonisa ngokupheleleyo ixabiso layo kuphela ngobukrelekrele." Ngeminqweno yeengcali ezininzi, esi sivakalisi siye sangena ngokuthe ngcembe kwinqanaba lokuziqhelanisa ukusuka kwingcamango. Ukususela kulo nyaka, abavelisi baye baqala ukunikela ingqalelo kwi-intellectualization yeemveliso zabo. Nangona ubukrelekrele bebuyinto eshushu kwishishini ngaphambi koko, ukusukela oko ukukhanya okukrelekrele kwangena kwimarike yaseTshayina ngeminyaka yoo-1990, ibikwimeko yophuhliso olucothayo ngenxa yezithintelo zolwazi lokusetyenziswa kweemarike, imeko yentengiso, ixabiso lemveliso, ukukhuthaza kunye nokunye. imiba.

Ubume bokukhanya kwe-LED

Ifowuni ephathwayo yolawulo olukude ngqoIsibane se-LED; Ngokusetwa kwencwadana kunye nomsebenzi wememori okrelekrele, imowudi yokukhanyisa inokulungiswa ngokuzenzekelayo ngamaxesha ahlukeneyo kunye nemiboniso, ukwenzela ukuba umoya wokukhanyisa usapho unokutshintshwa ngokuthanda; Ukusuka kwizibane zangaphakathi ukuya kulawulo olukrelekrele lwezibane zasesitalatweni zangaphandle… Njengendawo enenzuzo ye-LED, ukukhanya okukrelekrele kuthathwa njengeyona ndawo ibalulekileyo yokukhula ukonyusa ixabiso elongezelelweyo lokukhanyisa kwe-semiconductor, kwaye kutsale amashishini amaninzi ukuba ajoyine. Ukukhanya okukrelekrele kwe-LED kuye kwaba yenye yeendlela eziphambili zophuhliso lobugcisa kumashishini okukhanyisa i-semiconductor.

Ngokomzekelo, ukulawulwa kweqondo lokushisa kwe-LED kunye nokulawulwa kokukhanya kwesitrato ohlakaniphile kusetyenziswe ikakhulu kwiimveliso zangoku. KodwaUkukhanya okukrelekrele kwe-LEDkuya kuba ngaphezu koko, uSilvia L Mioc ukhe wathi ukukhanya okukrelekrele kuye kwatshintsha ishishini lokukhanyisa ukusuka kwimowudi yezixhobo zenkunzi ukuya kwimodi yenkonzo, ukwandisa ixabiso elongezelelweyo leemveliso. Ukujongana nekamva, isiphakamiso esihle kakhulu kukubona indlela yokubuyisela ukukhanya kwinxalenye ebalulekileyo ye-Intanethi kunye nokudibanisa ukhathalelo lwempilo, amandla, iinkonzo, ividiyo, unxibelelwano kunye nokunye.

UkrelekreleUkukhanya kwe-LEDinkqubo kunye neteknoloji yokuva

Kwiimeko ezininzi, abantu bahlala besithi inkqubo yokulawula izibane ezihlakaniphile ibhekisela kwinkqubo yokulawula ukukhanya kwangaphakathi. "Inzwa likhonkco elibalulekileyo lokuqonda ukukhanya okukrelekrele". Kwingxelo, ushwankathela ukubunjwa kwenkqubo yolawulo lokukhanyisa olukrelekrele, oko kukuthi inzwa + ye-MCU + yokulawula ukubulawa + i-LED = ukukhanya okukrelekrele. Eli phepha lichaza ngokubanzi ingcamango, umsebenzi kunye nokuhlelwa kweenzwa, kunye nokusetyenziswa kwazo kunye nohlalutyo lomzekelo ekukhanyeni okuhlakaniphile. Unjingalwazi uYan Chongguang ukwahlula iisensori zibe ziindidi ezine: i-pyroelectric infrared sensors, i-ultrasonic sensors, i-Hall sensors kunye ne-photosensitive sensors.

I-LED idinga intsebenziswano yenkqubo ekrelekrele ukubhukuqa ingqikelelo yokukhanyisa yemveli

Ukukhanya kwe-LED kwenza umhlaba wethu wonge ngakumbi amandla. Ngexesha elifanayo, ukudibanisa ukukhanya kwe-LED kunye nemodi yokulawula kunokuba lula kwaye kuluhlaza. Izibane ze-LED ziyakwazi ukuhambisa izibonakaliso zenethiwekhi kunye nokulawula iimpawu ngokukhanya, ukuthumela izibonakaliso eziguquguqukayo, kunye nokugqiba ukuhanjiswa kolwazi kunye nemiyalelo. Ukongeza kokudibanisa inethiwekhi, izibane ze-LED zinokusebenza njengomphathi wezixhobo ezahlukeneyo zendlu. Ngokukodwa, ukukhanya kwesakhiwo kuyona nto ibalulekileyo kwimarike yesicelo; Uthe ukusetyenziswa kwamandla kwezakhiwo kuphezulu kakhulu. Amanye amazwe aseYurophu naseMelika aphuhlise iinkqubo zokukhanyisa ezikrelekrele ukulungiselela le njongo. Ukusetyenziswa kwenkqubo yokulawula ukukhanya kunokubonakalisa ngcono iingenelo zayo ekugcinweni nasekulawuleni amandla.
