Abakhiqizi Bobuhlalu Bezibani Ze-LED Bafakwe Ngokuqondile Ukukhuluma Ngomehluko Phakathi Kobuhlalu Besibani Se-LED

Bafake ngokuqondile abakhiqizi bobuhlalu besibani se-LED ukuze bakhulume ngomehluko phakathi kolwazi lwebakaki lobuhlalu besibani se-LED: Njengamanje, kukhona abakaki be-aluminium, abakaki bethusi, abakaki bethusi, njll. emakethe. Ngisho noma kuwubakaki wethusi, inani lentengo yesiliva lihlukaniswa libe phezulu naphansi. Imakethe ngokuvamile ibizwa ngokuthi isiteji esihle. Umehluko phakathi kosayizi we-chip: Usayizi we-chip ovame ukubikwa yi-MIL. Kunzima ukuhlukanisa ubukhulu be-chip. Kungu-230 square MIL, ubukhulu bendawo ye-chip buyindlela enhle yokuhlukanisa usayizi we-chip. Umehluko phakathi kolwazi lomugqa wokushisela: I-chip nobakaki kusetshenziselwa ukuqedela ukuxhuma kwe-electrode ngendlela yegolide yokushisela. Njengamanje, kunezinhlobo ezimbili zemigqa ye-alloy kanye nemigqa yegolide ehlanzekile emakethe. Imigqa yegolide ehlanzekile ihlukaniswe yaba ngu-0.7, 0.9, 1.0, 1.2, njll. Ukuqina komugqa wegolide, iqembu le-thermal eliphansi, isikhathi eside sokuphila, yonke into kufanele ibuzwe mayelana nezinto kanye nobubanzi bomugqa wegolide. Umehluko phakathi kwe-fluorescence powder: ubuhlalu obukhanyayo obumhlophe benziwe nge-blue-light chip kanye nempushana ye-fluorescent ephuzi. I-fluorescent powder ihlukaniswe ikakhulukazi i-aluminium acid ne-silicate. Ukusebenza kwe-aluminate kungcono kune-silicate. , ukusebenza kwe-YAG kuzinzile, kuphansi ekukhanyeni, futhi ukuzinza kwamakhemikhali we-silicate ngokwawo akulungile, kodwa ukukhanya kuphakeme kune-YAG. Uma ufuna ukwenza umkhiqizo ngokusebenza okuzinzile, ungakhohliswa yilokho okubizwa ngokukhanya okuphezulu. Lokhu kuyinkinga. Umehluko phakathi kweglue: Impushana ye-fluorescent kufanele ixutshwe ngeglue naku-chip. Izinga leglue lithinta ukubola kokukhanya kanye nokukhukhuleka kombala. Isikhathi seglue esimpofu sizoba phuzi, futhi ukubola okukhanyayo kuzokwanda. Iglue enhle yijeli. Glue.
