I-LED edibeneyo. Yintoni enokuba lula?

Eli nqaku lichaza indlela yokudibanisa ii-LED, imigaqo kufuneka ilandelwe ukuze kuqinisekiswe ukusebenza kakuhle kwezixhobo. Iintlobo zoxhumo lwabo zichazwe.

I-LED edibeneyo. Yintoni enokuba lula?

Ezi zinto ezincinane namhlanje ziyaziwa ngokubanzi. Wonke umntu unezibane ze-LED, izibane, izigulane kunye nezinye izinto ezikhanyayo, ezikhanyayo kunye namathoyizi. Zineenzuzo ezininzi kunye neenzuzo ngaphezu kwamabala okukhanya okuqhelekileyo, kodwa kukho izinto ezikhethekileyo zokusetyenziswa. Ngoko udibanisa njani ii-LED?

Ukusebenzisa ngokufanelekileyo izixhobo, kufuneka ulandele ngokungqongqo iimfuno ezimbalwa ezilula, kwaye ke abayi kuzisa nayiphi na ingxaki kwaye baya kukhonza ixesha elide.

Into ebalulekileyo kukuba ungayikhohlwa imithetho emibini engundoqo:

1. Ii-LED zixhobo ze-semiconductor kwaye zinendlela yokuqhuba enye, okanye, ngamanye amagama, ukuxhamla kwee-LED kufuneka kwenziwe kwi-polarity echanekileyo (njengokuxhuma ibhetri, awukwazi ukuxuba "+" kunye "-"). Ngaphandle koko, i-LED iya kutshisa okanye ayiyi kukhanya.

2. Isixhobo silawulwa ngoku. Yintoni ekhoyo yombane, akudingekile ukuba uchaze, kodwa inyaniso yokuba ubukhulu bayo buyahluka, kubalulekile ukwazi. Ixabiso eligeleza kuyo nayiphi na ikhonkco lichongwe ngoluhlu lwayo ukuchasana. Oku kwenzekayo xa iphepheni ivuliwe - ukuba ivuliwe kancane, amanzi aya kuhamba ngomlambo omncinci, ukuxhatshazwa kwephepheni kumanzi ahambayo mkhulu; Ukuba uvula ngokupheleleyo, amanzi aya kuhamba ngejeti elinamandla, ukuxhatshazwa kwipompo yamanzi iya kuba yincinci.

Ukusebenza ngokuchanekileyo kunye nexesha elide le-LED, ixabiso langoku limele liphumelele kulo, eli lathisi linqunywe yimpawu ze-LED. Ukuba okwangoku liphezulu kakhulu, umbane uya kutshisa. Oku kufana nento yokuba sizama ukubonelela ngamanzi ngcinezelo nge-hose ye-rubber hose. Ukuba ingcinezelo ayinamandla kakhulu, ngoko amanzi aya kuba nexesha lokudlula kwi-hose, kwaye yonke into iya kulungiswa. Ukuba likhulu kakhulu, i-hose iya kuqhekeza. Kuya kufana ne-LED. Ukuba okwangoku kudlula ixabiso elifunekayo, isixhobo siya kutshisa.

Ubukhulu beli xesha lilawula ulwalamano. Kufuneka kukhunjulwe ukuba ukudibanisa kwama-LED kumthombo wombane kungenziwa kuphela ngenxa yokumelana. Yintoni, kwaye kukuphi ukuchasana okufanele kusetyenziswe ukusetyenziswa ngokuqhelekileyo kwe-LED, akusiyo isihloko sale nqaku. Ukuba kukho umnqweno wokwenza idivaysi izitshise ngokwaneleyo, kwanele ukufumana intetho kwivenkile ukukhetha ukhetho. Kwaye kuncinci ukufumana isinyithi eselungelelanisa ukuxhamla kwezinto phakathi kwabo.

Konke oku ngasentla kusebenza kwimeko yezixhobo zokuxhuma kumthombo we-DC, Ibhetri, ibhetri okanye into efanayo. Xa uzama ukuxhuma ii-LED kumnatha womnatha, ngaba. Umthombo wokutshintsha kwee-voltage, kuya kufuneka usebenzise idiode yokulungisa kwakhona, ungayikhohlwa ngolawulo 1.

Nangona kunjalo, kunokukho imeko apho kufuneka usebenzise ii-LED ezininzi ngexesha elinye. Kule meko, kukho iindlela ezimbini zokuqwalasela le mfuneko.

Xa ufanele ufezekise, umzekelo, ukukhanya okukhulu, sebenzisa uxhumano olufanayo lwe- LED. Emva koko zonke izinto zifana ngokufanayo, zixhobo ezininzi kuphela ezixhunyiwe kumthombo wamandla ngexesha elinye. Ungakulibali ukuba udibaniso lwawo ngamnye lufanele luvele ngokumelana nalo.

Ukuba ufuna ukwenza into efana negrafu, ngoko kufuneka udibanise ii-LED kwinqaku. Kule meko, uhlobo olufanayo lweefowuni luxhunyelelane omnye komnye ukuze i-minus yangaphambili idityaniswe kunye neyona elandelayo. Ngenxa yoko, ufumana ikhonkco eneemiphelo ezimbini ezikhululekile-kunye kunye nokunciphisa. Kwaye le khoyunithi isebenze njenge-LED enye, kwaye inokudibaniswa ngokumelana nomthombo wamandla.
