Yiziphi izingxenye eziphambili zamalambu we-LED?

Ngokwamukelwa okusabalele kweUkukhanyisa kwe-LED, amalambu wendabuko we-Impandescent kanye ne-Fluorescent kancane ayathathelwa indawo. Izibani ze-LED azigcini ngokusebenza kahle kwamandla futhi zibe nesikhathi sokuphila samahora angaphezu kuka-50 000 kodwa futhi zinikeza ithuba lokuba ne-mercury-free nemvelo enobungane. Kepha kuthiwani ngempela ukukhanyiswa kwe-LED? Le ndatshana izokusiza uqonde ubuchwepheshe ngemuva kokukhanya kwe-LED ngokuhlaziya izingxenye eziyinhloko zamalambu we-LED.

Umsebenzi:I-Chip ye-LED yingxenye ekhanyayo emcabangweni yokukhanya kwe-LED. Lapho ugesi kagesi udlula, ama-elektroni ku-semiconductor wezinto ezifunwayo enze uguquko futhi akhishe ama-photons, anqume ngokuqondile umbala nokukhanya kokukhanya.

Okubonakalayo:Ama-chips akhiqizwa ngokuyinhloko ezintweni ze-semiconductor ezinjenge-gallium nitride (gan) ne-gallium arsenide (gaas). Ama-chip asezingeni eliphakeme angafaka izinto ezinjenge-aluminium ne-indis ukuthuthukisa ukusebenza kahle okukhanyayo nokuqina.

Umsebenzi:Isakhiwo sesakhiwo se-EcASpption Indima yayo ukuvikela i-chip kwi-oxidation kanye nomonakalo womzimba ngenkathi ulungiselela ukusatshalaliswa kokukhanya. I-Resin ye-Eccopsertion isiza ukusakaza ukukhanya okukhishwe yi-chip ngokulinganayo, ukugwema ukugxila, imishayo enokhahlo.

Okubonakalayo:Izinto ezijwayelekile ze-Encopsetion Resin zifaka i-epoxy resin noma i-silicone engamelana nezinga lokushisa. Imikhondo evuthayo ngokuvamile yenziwe ngesiliva noma izintambo zegolide. Ababonisi bangenziwa ngensimbi noma ngeplastiki, kanye nezinhlobo zama-enchlation zifaka phakathi-hole (ngokumelana nesimo sezulu esinamandla) kanye nentaba engaphezulu (ngosayizi omncane) phakathi kwabanye.

Umsebenzi:Uhlelo lokuhlanza ukushisa, oluhlanganiswe nezinhlaka zokushisa kanye nezakhiwo ezishisayo, zidluliselwa ngokushesha ukushisa kude ne-chip ukuvikela amazinga okushisa ngokweqile angaholela ekunciphiseni okukhanyayo futhi anciphise isikhathi sokudla okukhanyayo futhi anciphise impilo.

Okubonakalayo:Ukushisa okushisa kwenziwa ikakhulukazi nge-aluminium alloy, ngemikhiqizo ephezulu esebenzisa izinto zokwakha zethusi noma zenhlanganisela. Ukunamathelisa okushisayo kungasetjenziswa futhi ukuthuthukisa ukusebenza kahle kwe-thermal.

Umsebenzi:Ukuhlinzekwa kwamandla okushayela kubandakanya i-PCB kanye ne-Convertant Chiry Circuit, ebhekele ukuguqula amandla e-AC kumandla we-DC anzile futhi alawule ukushushiswa kwamanje ukuvikela ukuguquguquka kwamanje kwe-chip.

Okubonakalayo:Amabhodi wesifunda ngokuvamile enziwa kusuka kuma-PCBS aqiniswe nge-fiberglass, amelana nokushisa futhi afaka.

Umsebenzi:Izakhi ze-Optical ziqukethe ama-lens kanye nama-mbondela. Amalensi alawula ukuqondiswa kokusakazwa kokukhanya ngokusebenzisa izimiso zokuphikisa noma zokubonisa futhi angaguqula i-angle ye-beam. Abandlayo baqoqa ukukhanya okuhlakazekile ngokusebenzisa amajamo wejometri njenge-paraboloids noma ama-ellipsoids futhi akuqondise, kunciphisa ukulahleka okukhanyayo.

Okubonakalayo:Ama-lens ajwayele ukwenziwa nge-PMMA, i-PC, noma ingilazi, futhi angafaka ukumboza okungamelana ne-UV ukunciphisa okuphuzi. Ababonisi bavame ukwenziwa nge-aluminium, yethusi noma ipulasitiki.

Umsebenzi:Izindlu ngokuyinhloko zivikela izingxenye zangaphakathi ezivela emithonjeni yangaphandle futhi zivikele ukulungiswa komonakalo.

Okubonakalayo:Ukulungiswa kwangaphandle kuvame ukusebenzisa i-aluminium alloy yokumelana nokugqwala. Ukulungiswa kwendlu kungasebenzisa ipulasitiki elingasindi kahle ngokusebenza kwezindleko.

Okuqukethwe okungenhla kuhlinzeka ngokuchazwa okuningiliziwe kwesakhiwo samalambu we-LED. Sekukonke, ukusebenza kokukhanya kwe-LED kuncike ekwenzeni izingxenye ezihlanganisiwe zezakhi zalo. I-chip inquma ukusebenza kahle okukhanyayo, uhlelo lokuhlanza ukushisa luthinta impilo yempilo, futhi amandla okuphakela amandla okuqinisekisa ukuqina. Le ndatshana ingakusiza uqonde umehluko phakathi kwezakhi ezibalulekile futhi usize ekukhetheni imikhiqizo efanelekile.

Njengomhlinzeki wokukhanyisa oholayo we-LED,ToppoUngakunikeza amalambu we-LED ahlukahlukene aphezulu bese unikeza izixazululo ezenziwe ngezifiso zesikhala sakho. Uma unemibuzo mayelana nokukhanya kwesimanje, sicela ukhululekeXhumana nathi!
