Ngaba uyayazi imigangatho emine yobuchwephesha yezibane zobungqina bokudubula kwe-LED?
Isibane sobungqina bokudubula kwe-LED sesinye sezibane ezikhusela ukuqhuma.Umgaqo wayo uyafana naleyo yesibane sobungqina bokudubula.Umahluko kukuba umthombo wokukhanya osetyenzisiweyo ngumthombo wokukhanya we-LED, obhekiselele kwisibane esithatha amanyathelo athile ahlukeneyo ukukhusela umxube ojikelezayo oqhumayo ukuba ungavuthi.Ngoko ke, kubaluleke kakhulu kuthi ukuba sithenge izibane ze-LED ezibonisa ukuqhuma.Xa kuthengwa, kufuneka siqonde imigangatho emine yezobuchwepheshe yezibane ze-LED ezibonisa ukuqhuma.
1. Umthombo wokukhanya we-LED
Kusetyenziswa ukukhanya okuphezulu, ukukhanya okuphezulu kunye nokukhanya okuphantsi-ukubola kwe-LED, kunye nezinto ezihlangabezana neemfuno zisetyenzisiweyo, njengezibane ze-phosphor zegolide ezipakishweyo.Xa uthenga, nceda ukhethe izibane zokukhanyisa kwimizi-mveliso ezisetyenziselwa ngokukodwa imveliso.
2. Amandla okuqhuba
I-LED licandelo le-semiconductor eliguqula ii-electron ze-DC zibe amandla okukhanya, ngoko ukuqhuba okuzinzile kufuna iitshiphusi zokuqhuba amandla aphezulu, kwaye imisebenzi yembuyekezo ye-PU iyafuneka ukuze kuqinisekiswe ukusebenza kakuhle kwamandla.Amandla yinto ephambili yesibane sonke.Okwangoku, umgangatho wombane we-LED kwimarike awulingani kwaye uxutywe.Unikezelo lwamandla okuqhuba olulungileyo alunakuqinisekisa kuphela imveliso yeDC ezinzileyo, kodwa ikwaqinisekisa ngokupheleleyo ukuphuculwa koguqulo olusebenzayo.Le parameter ibonisa uhlobo lokwenene lokugcina amandla lwesibane kwaye aluyi kubangela inkunkuma kwigridi yamandla.
3. Imbonakalo kunye nesakhiwo sesibane se-LED sobungqina bokuqhuma kunye nenkqubo yokutshatyalaliswa kobushushu obuqinileyo
Ukongeza kwimbonakalo ephezulu, umthombo wokukhanya ophezulu kunye nokunikezelwa kwamandla, isibane esilungileyo sibaluleke ngakumbi ingqiqo yesakhiwo segobolondo.Ibandakanya ingxaki yokutshatyalaliswa kobushushu yesibane se-LED.Njengoko i-LED iguqula amandla esibane, inxalenye yamandla ombane nayo iguqulwa ibe ngamandla obushushu.Ukukhokela okutshisayo kukhutshwe emoyeni ukuze kuqinisekiswe ukuzinza kwesibane se-LED.Ukushisa okuphezulu kwesibane se-LED kuya kukhawulezisa ukubola kokukhanya kunye nokuchaphazela ubomi besibane se-LED.Kuyafaneleka ukukhankanya ukuba iteknoloji ye-chip ye-LED iphucula rhoqo, kunye nokusebenza kakuhle kokuguqulwa kuphucula.Ubushushu obusetyenzisiweyo ekuguqulweni kwamandla ombane buya kuba buncinci, kwaye isixhobo sokutshatyalaliswa kobushushu siya kuba sincinci.Kwakhona ngenxa yokuba ezinye zeendleko eziphantsi ziluncedo kwi-LED, kodwa oku Ngaba nje isalathiso sophuhliso lwetekhnoloji, iiparamitha zangoku zokutshatyalaliswa kobushushu bezindlu kufuneka zinikwe ingqalelo.
Okwesine, i-lens yesibane sobungqina bokuqhuma kwe-LED
Ihlala ingahoywa ngabanye abayili.Enyanisweni, ukulahleka kokukhanya kuya kwenzeka.Isalathiso se-refractive se-lens ekukhanyeni sikwachaphazela ngokunzulu isiphumo sokugqibela esikhanyayo.Ukuhanjiswa kwe-lens engcono kunokufikelela ngaphezu kwe-93. Ngenxa yeendleko, umgangatho welensi nawo ubaluleke kakhulu.Ngoko ke, ukuze kugcinwe iindleko, abanye abavelisi basebenzisa izixhobo ze-lens ezingabizi kufuneka zibe zixhobo zesibini kwaye zibe ne-transmittance yokukhanya malunga ne-70 yeedola, ezingabonakaliyo ngeso lenyama kwaye zikhohlisa abathengi.Nangona kunjalo, iziphumo zovavanyo lwezixhobo zabo eziphathekayo zilula kakhulu.Izinto eziphathekayo zihlwempuzekile, kwaye ziya kuba tyheli emva kwexesha elide.
