Umehluko Phakathi Kwe-LED Yomthombo Wokukhanya Ohlanganisiwe

Umthombo wokukhanya wokukhanya kwesibani se-LED esisebenzayo, ukulimala komthombo wokukhanya ohlanganisiwe we-LED noma ukuqhekeka kubangela umthombo wokukhanya ungakwazi ukukhanya futhi isibani esifile sibi. W, ngaphezu kuka-70LM/W kanye no-100LM/W wamalambu e-T5 anamalambu avamile e-fluorescent, okwenza umphumela wokukhanya ophelele wamabhokisi okukhanya we-LED ube phezulu. Umphumela wokukhanya wesikhashana we-LED ubhekisela ekusebenzeni kahle kokukhanyisa komthombo wokukhanya we-LED lapho uqala ukusebenza, owaziwa nangokuthi umphumela wokukhanya wesimo esibandayo. Iwukugeleza kokubona okusheshayo kukalwa ishayela elithile elifushane lamanje ngomthombo wemitha. Isikhathi sokushisa esingaguquki se-substrate, ububanzi be-pulse yokushisa ngokuvamile buyi-1- amashumi e-ms. Imithombo yokukhanya edidiyelwe Ukuqina kwe-LED noma imithombo yokukhanya okubangelwa ukushisela noma ukusetshenziswa, intambo yegolide iphukile ngesikhathi sokunwetshwa okushisayo nokufinyela kwe-colloid, okubangela izibani ezifile; ngaphezu kwalokho, umthombo wokukhanya we-LED ungumthombo wokukhanya wesimo esiqinile. Lokhu kusho ukuzinza. Ngaphezu kwalokho, impilo yesevisi yezibani ze-sodium ezicindezelayo nezibani zegolide ze-halide ngokuvamile zingaphansi kwamahora angu-6000, futhi inkomba yokunikeza umbala ingaphansi kwama-30; I-LED inezinzuzo ezibalulekile ezifana nokusebenza kahle okuphezulu, ukonga amandla, impilo ende (amahora angu-50,000), ukuvikelwa kwemvelo, inkomba ephezulu yokunikeza imibala ( > 75), njll. Indlela yokusebenzisa ngempumelelo ama-LED ekukhanyisweni komgwaqo isibe yisihloko esithandwa kakhulu se-LED kanye nabakhiqizi bokukhanya komgwaqo. Njengomongo wezibani zomgwaqo ze-LED, ubuchwepheshe bokukhiqiza ama-chips e-LED kanye nobuchwepheshe bokupakisha obuhambisanayo bunquma ngokuhlanganyela amathuba okusebenza kwe-LED emkhakheni wokukhanyisa esikhathini esizayo. Isizathu esiyinhloko sokwehluleka okukhulu ukwehluleka ukuphuzi noma ukuncishiswa kwe-silicone noma ukunciphisa. Ama-electrode e-LED P no-N asemthethweni asohlangothini olufanayo lwe-LED. Okwamanje kufanele agezele kungqimba lwe-N-GAN ngokuvundlile, okuholela kumanje ominyene, ukushisa kwendawo okuphezulu, futhi kukhawulele amandla okushayela. Inyamalala. Enkambweni yokusetshenziswa kwesikhathi eside, izinga lokushisa eliphezulu elibangelwa ukuchithwa kokushisa okungalungile lithinta ukusebenza nokudluliselwa kwe-silicone, okubangela ukuncishiswa kwamandla okukhanya okukhulu. Umthombo wokukhanya ohlanganisiwe we-LED awugcini nje ngokuba nesivinini sokubhula ngokushesha, kodwa futhi unama-engeli amaningi uma uyisebenzisa. Ayikho ingcindezi ekuqageleni, emaceleni, nasekuqageleni okutshekile. Ngenxa yenqubo yenqubo eyinkimbinkimbi, inqubo yenqubo ayikwazi ukulungiswa. Inqubo yesicelo senqubo ehlanekezelwe ilula, futhi ukukhanya okubi kungalungiswa. Uma kuqhathaniswa nenqubo yokupakisha esemthethweni, ukuminyana kokupakisha kwenqubo ehlanekezelwe kukhuphuke izikhathi eziyi-16. Ukupakisha okuhlanganisiwe kubizwa nangokuthi i-polycrystalline packaging. Inani lama-chips e-LED kusisekelo se-substrate ngokusekelwe kumandla adingekayo liyanqunywa. 3W high -brightness high -power LED amadivayisi. Okokugcina, i-chip ifakwe ku-chip ngento ephezulu yenkomba ye-refractive ngokuya ngokuma kwe-optical design. Iphakethe le-Cob “Imodeli yomsuka wokukhanya we-COB →Amalambu we-LED ”, Ingafakwa ngokuqondile ngama-chips amaningi ku-MCPCB ebhodini lesifunda lokunyathelisa elisekelwe ensimbi, futhi ikhiphe ngokuqondile ukushisa nge-substrate ukuze konge izindleko zokupakisha ze-LED, izindleko zokukhiqiza imojula yenjini ekhanyayo, nezindleko zokukhanyisa kwesibili. Ngokusebenza, ngokuklama okunengqondo kanye ne-microscope, imojula yomthombo wokukhanya we-COB ingagwema ngokuphumelelayo ukungalungi kokukhanya nokuxhopha okukhona ekuhlanganisweni kwamadivayisi omthombo wokukhanya wokuhlukanisa; kungase futhi kuthuthukise ngempumelelo umbala womthombo wokukhanya ngokwengeza inhlanganisela ye-chip ebomvu efanele ucansi. Umthombo wokukhanya ohlanganisiwe wevolumu ye-LED yehliswe ngo-80%, ukuhlukaniswa kombala okhanyayo kufana kakhulu, futhi izindleko ziphansi, kodwa ama-chips amancane azobeka phambili izidingo zobuchwepheshe eziphakeme kakhulu zokunemba kwemishini nokunamathisela okuqinile kwe-crystal tinnodium.
