Phakathi neminyaka yokusebenza nabakhiqizi be-luminaire, ngokuvamile sinomuzwa wokuthi abakhiqizi be-luminaire bayanqikaza ukuthenga izinto ezingcono zamandla we-LED.Ngokuphambene nalokho, abazi ukuthi bangahlukanisa kanjani ugesi othengiwe we-LED, futhi bakhathazekile ngokuthi bakhokhe inani eliphezulu yini lekhwalithi ephansi yamandla kagesi we-LED.Ngakho-ke, njengomkhiqizi wokukhanyisa, kunzima ukuphendula ukuthengwa kwamandla kagesi we-LED.Ngenxa yokuthi ikhwalithi yokushintshwa kwamandla kunzima ukuyihlola, isineminyaka engama-4 amahora endaweni yayo yokucubungula, kanti abanye baze baneminyaka engama-24-72.Kodwa-ke, lo mkhiqizo omdala uvamise ukuba ngu-5% noma ngaphezulu phakathi nezinyanga ezi-3-6 zokulethwa.Ngokuvamile, ezimweni ezimbi ezinjalo, abakhiqizi be-luminaire bayahlupheka, babe amakhasimende, futhi balahlekelwe amakhasimende.
Kuthiwani ngokuthatha ikhwalithi yomthombo wamandla we-LED?Singayikhomba ezicini ezilandelayo:
Okokuqala:phusha i-chip-IC yokucubungula.
Okuqukethwe okuyinhloko kokunikezwa kwamandla okushayela kuyisekethe ehlanganisiwe, futhi izinzuzo nezinkinga zesifunda esihlanganisiwe zingathinta ngokuqondile zonke izinto zokushintsha amandla.Amasekhethi ahlanganisiwe abashayeli bezimboni ezinkulu ahlanganiswe ezimbonini zokupakisha ezinkulu neziphakathi nendawo;ubuchwepheshe besekethe obudidiyelwe babashayeli bezimboni ezincane ezicutshungulwayo wukukopisha ngokushesha idizayini yesikimu sokuphromotha samafekthri amakhulu, nokuthola ukupakishwa kwezimboni zokupakisha ezincane nezinosayizi omaphakathi, ezingakwazi ngokuvamile ukuqinisekisa ukuvumelana kwamasekethe ahlanganisiwe weqoqo.nokuthembeka, okuholela ekutheni amandla okushayela angasebenzi ngaphandle kwesizathu ngemva kwesikhathi esithile sokusetshenziswa.Ngakho-ke, isifunda esihlanganisiwe ekunikezeni amandla kagesi we-LED siyenqaba ukupholishwa, okulungele umkhiqizi wesibani ukuthi abambe uhlelo lwesifunda oludidiyelwe futhi abale izindleko zokuphromotha, ukuze kuqinisekiswe intengo esebenzayo yomkhiqizo wokushintsha amandla kagesi.
Okwesibili:I-Transformer.
Iphrosesa esebenzayo ingabhekwa njengesikhungo semizwa yobuchopho yomuntu oshintsha ukunikezwa kwamandla, kuyilapho amandla okukhipha kanye nokumelana nokushisa okuphezulu kunqunywa i-transformer.Ama-Transformer athatha amandla e-AC amanje - amandla kazibuthe - amandla e-DC, futhi amandla e-kinetic engeziwe angasuthisa umshini.Okuqukethwe okuyinhloko kwe-transformer kuwumgogodla kanye nephakheji yocingo.
Izinga le-core liyisihluthulelo ku-transformer, kodwa njengobumba, akulula ukukubona.Ukuhlonza ukubukeka okulula ukuthi: ukubukeka kuhlanzekile, kuminyene futhi kugqamile, futhi uhlangothi olungemuva lupholishiwe futhi imbobo yokukhipha umoya iwumkhiqizo omuhle.Njengamanje, umgogodla kazibuthe osetshenziswa yi-Shanghai Nuoyi yi-PC44 magnetic core, esetshenziselwa ukwenza isikhunta, okuqinisekisa ukusebenza kahle okuphezulu kokushintshwa kwamandla kagesi.
Iphakheji yocingo yenziwe nge-copper core wire winding.Ikhwalithi yomkhiqizo we-copper core wire iyingxenye ebalulekile yokuphila kwenkonzo ye-reaction transformer.Izintambo ze-aluminiyamu ezigqoke ithusi ezinosayizi ofanayo ziyi-1/4 yenani lezintambo zethusi ezibomvu.Ngenxa yezizathu zezindleko nokucindezela kokusebenza, abakhiqizi be-transformer bavame ukuxuba ama-transformer nge-copper clad aluminium wire wraps.Khona-ke, lapho izinga lokushisa le-transformer likhuphuka, umonakalo awusebenzi, unikeza amandla okushintshanisa nokukhanya konke kungasebenzi.Njengomphumela walokho, izinto eziningi zokukhanyisa, ikakhulukazi lezo ezinamandla okushintsha ahlehlisiwe, ngokuvamile ashintshashintsha aye phezulu naphansi ngemva kwezinyanga ezingu-6 zokulethwa.Ungahlukanisa kanjani ukuthi ucingo lwe-copper core luwucingo lwethusi olubomvu noma i-aluminium ye-copper clad?Sebenzisa i-lighter ukuze ukhanyise futhi ushise ngokushesha i-copper clad aluminium.Ingakwazi futhi ukukala ngokunembile inani lokumelana lekhoyili ye-solenoid.
Okwesithathu:ama-electrolytic capacitors kanye nama-chip ceramic capacitors.
Sonke siyazi ukuthi sonke siyayazi ikhwalithi nempilo yesevisi yama-electrolytic capacitor, futhi sonke siyithatha ngokungathi sína.Kodwa-ke, sivamise ukungayinaki imithetho yekhwalithi yomkhiqizo yokuthumela ama-capacitor.Eqinisweni, isikhathi sokuphila se-capacitor etholakalayo silimaza kakhulu impilo yonke yokushintsha kwamandla kagesi.Imvamisa yokusebenza yokushintsha kwamandla ekupheleni kokuhola kufinyelela izikhathi ezingu-6,000 ngomzuzwana, okuholela ekwandeni kokumelana nokusinda kwe-capacitor nokukhiqizwa kwamakhemikhali afana nokungcola.Ekugcineni, i-electrolyte yebhethri ye-lithium iyashisa futhi iyaqhuma.Kutuswa ngokuqinile ukuthumela ama-electrolytic capacitor: khetha indlela ekhethekile ye-electrolytic ye-LED, futhi imininingwane yemodeli evamile iqala ku-L. Kulesi sigaba, izindlela zethu zokuthekelisa ze-electrolytic zonke zingama-electrolytic capacitor anempilo yesevisi ephezulu ye-Aihua.
Ama-Ceramic capacitor: Izinto zokwakha zihlukaniswe nge-X7R, X5R kanye ne-Y5V, futhi amandla athile e-Y5V angafinyelela kuphela ku-1/10 yenani elithile, futhi inani le-capacitance elijwayelekile libhekisela kuphela ku-volts angu-0 ngesikhathi sokusebenza.Ngakho-ke, lokhu kumelana nokukhetha okuncane kuzoholela emehlukweni wezindleko, kwehlise kakhulu impilo yesevisi yokushintshwa kwamandla kagesi.
Okwesine:isimiso sesifunda kanye nendlela yokushisela yokushintsha imikhiqizo yokuphakelwa kwamandla.
Hlukanisa ikhwalithi yohlelo lokuklama: Ngaphezu kombono wochwepheshe wezobuchwepheshe, lungabuye luhlukaniseke ngokwezinye izindlela ezibukwayo, njengokuhlela okunengqondo kwezingxenye, ubunono, umoya ohlelekile, ukushisela okukhanyayo, nokuphakama okucacile.Uchwepheshe onekhono akajwayele ukwenza imiklamo engcolile.Okwezintambo, ukwenziwa kwezandla kanye nezingxenye nakho kuwukubonakaliswa okukhulu kokuntuleka okukhulu kwamandla obuchwepheshe.
Indlela ye-Welding: i-welding manual kanye nenqubo ye-welding ephezulu.Njengoba sonke sazi, ikhwalithi ephezulu yenqubo yokushisela yemishini ezenzakalelayo kufanele ibe ngaphezu kokushisela okwenziwa ngesandla.Indlela yokuhlonza: noma ngabe kuneglue ebomvu ngemuva (inqubo yokucubungula i-solder paste + i-welding kagesi nayo ingaqedela ukushisela okuphezulu, kodwa izindleko zokulungisa ziphakeme kakhulu).
Ithuluzi lokuhlola i-SMD spot welding: AOI.Kusixhumanisi se-SMD, isikhungo singabheka isimo sokuchithwa kwe-desolder, i-solder engamanga, nezingxenye ezingekho.
Kulesi sigaba, ukukhanyisa kuzocwayiza ngemva kwesikhathi esithile sokusetshenziswa, okubangelwa ngokuyinhloko ukukhishwa kwe-soldering yamandla okushintshanisa noma ubuhlalu besibani se-LED.Ukuhlolwa kokuncibilika kwalo mkhiqizo akulula ukudlula ukuhlolwa kokuguga, ngakho-ke kuyadingeka ukusebenzisa i-AOI ukuze uhlole ikhwalithi yesichibi sokushintshwa kwamandla kagesi.
Okwesihlanu:Hlola ama-racks aguga namagumbi okushisa aphezulu okuguga ngobuningi ukuze ushintshe imikhiqizo yokuphakelwa kwamandla.
Kungakhathaliseki ukuthi izinto zokusetshenziswa kanye nokukhiqizwa zinhle kangakanani ezintweni ezingavuthiwe kanye nemikhiqizo yamandla okukhiqiza, noma ukuguga kufanele kubhekwe.Kunzima ukugada imibiko yokuhlola engenayo yezingxenye ze-elekthronikhi nama-transformer amandla.Kuphela ngokuya ngokuguga kokushintshwa kwamandla kagesi kanye nokuhlolwa kwesampula kokushisa okuphezulu kwegumbi lokushisa eliphezulu eliqhubekayo, lapho ukuthembeka kwekhwalithi yokushintshwa kwamandla kagesi kanye nokuthi izinto zokusetshenziswa zinezingozi zokuphepha zingabhekwa.
Umthelela wenani elikhulu lokuhlola amasampula okushisa aphezulu okuqhubekayo: Ukungasebenzi kahle kokushintsha izinsiza zamandla kulesi sigaba kuphakathi kwephesenti elilodwa nengxenye, futhi lokhu kungasebenzi kuzotholakala kuphela lapho izinkulungwane zokuguga okuqhubekayo okunokushisa okuphezulu.
Igumbi lokushisa eliphezulu eliqhubekayo lingakwazi ukulingisa indawo yemvelo enokhahlo lapho ugesi oshintshwayo usebenza khona.Ukuhlolwa kwamasampula ngaphansi kwamazinga aqinile kungadalula inani elikhulu lezinkinga ezifana nezikimu zedizayini ezingezona ezesayensi, izinto zokusetshenziswa ezingezinhle, izinto zokukhanyisa ezingasebenzi kahle, kanye nomthelela wezinqamuli zesekethe zamandla kagesi aphezulu.
Ukuguga kwesikhathi eside ekamelweni lokushisa: khetha ukwehluleka okungahleliwe njengokudilizwa, ukuvuza kwezingxenye, umthelela, njll., hlunga ukungasebenzi kwasekuqaleni kwezingxenye, futhi wehlise ngokunengqondo izinga lokwehluleka komkhiqizo oqediwe (1% kuya ku-1/1000) .
Ezingeni lokushisa lasekamelweni, ukuguga kudla imishini eminingi yokuguga, imishini nabasebenzi.Nsuku zonke, izimboni ezicubungulayo ezingu-100,000 zivula futhi zivale amandla.Imishini yokuguga nemishini ihlanganisa indawo okungenani engamamitha-skwele angama-500, enezikhundla zokuguga ezingaphezu kuka-10,000, futhi ukuguga komugqa wokukhiqiza sekuqediwe, okuyivelakancane embonini.
