Ungayibona kanjani ikhwalithi yemichilo yokukhanya ye-LED?

Ngokuthuthuka kwesayensi nobuchwepheshe, izibani ze-LED zingabonakala yonke indawo. Namuhla ngizokutshela ukuthi ungayibona kanjani ikhwalithi yemichilo yokukhanya kwe-LED. Imakethe yomugqa wokukhanya we-LED ixubile, futhi amanani entengo yemikhiqizo evela kubakhiqizi abajwayelekile kanye nemikhiqizo evela kubakhiqizi be-copycat ahluka kakhulu.

Singenza ukuhlonza kokuqala ngokusekelwe ekubukekeni okulula, futhi singasho ngokuyisisekelo ukuthi ikhwalithi yinhle noma yimbi.

Ingabonakala ikakhulukazi kulezi zici ezilandelayo:

1. Bheka amalunga e-solder. Imichilo yokukhanya ye-LED ekhiqizwa abakhiqizi bemigqa yokukhanya ye-LED ejwayelekile ikhiqizwa kusetshenziswa ubuchwepheshe be-SMT patch, kusetshenziswa i-solder paste kanye ne-reflow soldering. Ngakho-ke, amalunga e-solder emgqeni wesibani se-LED abushelelezi futhi inani le-solder alilikhulu. Amalunga e-solder asuka kuphedi ye-FPC aye ku-electrode ye-LED ngendlela eyi-arc.

2. Bheka ikhwalithi ye-FPC. I-FPC ihlukaniswe yaba izinhlobo ezimbili: i-copper-clad kanye nethusi eligoqiwe. I-foil yethusi yebhodi eline-copper-clad iyaphuma. Uma ubhekisisa, ungayibona ekuxhumekeni phakathi kwephedi ne-FPC. Ithusi eligoqiwe lihlanganiswe eduze ne-FPC futhi lingagotshwa ngokuthanda kwakhe ngaphandle kokuwa kwephedi. Uma ibhodi le-copper-clad ligobile kakhulu, ama-pads azowa. Izinga lokushisa elidlulele ngesikhathi sokulungiswa kuzophinde kwenze amaphedi awe.

3. Hlola ukuhlanzeka kwendawo yomugqa we-LED. Ingaphezulu lemichilo yokukhanya ye-LED ekhiqizwa kusetshenziswa ubuchwepheshe be-SMT ihlanzeke kakhulu, akukho ukungcola noma amabala abonakalayo. Kungakhathaliseki ukuthi ubuso bomugqa wokukhanya we-LED womgunyathi okhiqizwa ngokushisela ngesandla buhlanzwa kanjani, amabala neminonjana yokuhlanza kuyosala.

4. Bheka iphakethe. Imichilo yokukhanya ye-LED evamile ipakishwa kuma-anti-static reel, emiqulu engamamitha angu-5 noma amamitha angu-10, futhi ivalwe ezikhwameni zokupakisha eziphikisana ne-static kanye nomswakama-umswakama. Inguqulo ye-copycat yomugqa wokukhanya we-LED isebenzisa ireli egaywe kabusha ngaphandle kwezikhwama zokupakisha eziphikisana ne-static kanye nomswakama. Uma ubhekisisa i-reel, ungabona ukuthi kukhona imikhondo kanye nokuklwebheka endaweni esele lapho amalebula ekhishwa.

5. Bheka amalebula. Izikhwama ezivamile zokupakisha zomugqa wokukhanya we-LED namareli azoba namalebula aphrintiwe kuzo, hhayi amalebula aphrintiwe.

6. Bheka okunamathiselwe. Imichilo yokukhanya ye-LED evamile izofika nemiyalo yokusetshenziswa kanye nokucaciswa kwemigqa yokukhanya ebhokisini lokupakisha, futhi izofakwa nezixhumi zomugqa wokukhanya we-LED noma izibambi zamakhadi; kuyilapho inguqulo ye-copycat yomugqa wokukhanya we-LED ingenazo lezi zesekeli ebhokisini lokupakisha, ngoba Phela, abanye abakhiqizi basengakwazi ukulondoloza imali.

Qaphela emigqeni yokukhanyisa

1. Izidingo zokukhanya zama-LED ziyahlukahluka kuye ngezikhathi nemikhiqizo ehlukene. Isibonelo, uma izibani zekhawunta zobucwebe be-LED zibekwe kwezinye izitolo ezinkulu, sidinga ukukhanya okuphezulu ukuze sikhange. Ngomsebenzi ofanayo wokuhlobisa, kunemikhiqizo ehlukene efana nezibani ze-LED nemichilo yokukhanya enemibala ye-LED.

2. Amandla e-Anti-static: Ama-LED we-Anti-static anamandla aqinile e-anti-static anempilo ende, kodwa intengo izoba phezulu. Ngokuvamile i-antistatic ihamba phambili ngaphezu kuka-700V.

3. Ama-LED anobude obufanayo beza nokushisa kombala azoba nombala ofanayo. Lokhu kubaluleke kakhulu ezibani ezihlanganiswe ngobuningi. Ungakhiqizi umehluko wombala omningi esibani esifanayo.

4. Ukuvuza kwamanje kuyimanje lapho i-LED iqhuba ugesi ngokubuyela emuva. Sincoma ukusebenzisa imikhiqizo ye-LED enokuvuza okuncane kwamanje.

5. Ikhono elingangeni manzi, izidingo zezibani ze-LED zangaphandle nangaphakathi zihlukile.

6. I-angle ye-LED ekhipha ukukhanya inethonya elikhulu kumalambu e-LED futhi inezidingo ezinkulu zamalambu ahlukene. Isibonelo, sincoma ukusebenzisa amadigri angu-140-170 ngezibani ze-LED ze-fluorescent. Ezinye ngeke sizichaze kabanzi lapha.

7. Ama-chips e-LED anquma ikhwalithi eyinhloko yama-LED. Kunezinhlobo eziningi zama-chips e-LED, kuhlanganise nalawo avela kwamanye amazwe kanye nalawo avela e-Taiwan. Amanani emikhiqizo ehlukene ahluka kakhulu.

8. Usayizi we-chip ye-LED uphinde unqume ikhwalithi nokukhanya kwe-LED. Lapho sikhetha, sizama ukukhetha ama-chips amakhulu, kodwa intengo izoba phezulu ngokufanayo.
