Ama-LEDs aluhlaza okwesibhakabhaka i-SMD LED ene-SMT 3535 LED

3W Amandla aphezulu SMT 3535 LED ene-480mn LED

I-3535PBC48D60L45 iyi-LED enamandla aluhlaza okwesibhakabhaka ephezulu enecala le-3535 SMD LED. Ngenxa yokuthi kunelensi ebusayo ebusweni be-SMD LED, ungaphinda uyiqambe lokhu njengamandla amakhulu iDome Lens SMD LED. Imvamisa i-SMD LED eluhlaza okwesibhakabhaka (noma i-through-hole LED ) izokhipha i-470nm LED noma i-450nm yombala oluhlaza okwesibhakabhaka. I-480nm izosondela kakhudlwana kumbala oluhlaza ongu-520nm, ukuze umbala we-480nm ube lula ngokukhanya okuluhlaza okwesibhakabhaka. Ikhanya kune-470nm noma i-460nm LED eluhlaza okwesibhakabhaka. Qhathanisa namanye ama-LED aluhlaza okwesibhakabhaka, le wavelength ekhanyayo engama-480nm iluhlobo olukhethekile futhi akulula ukuwabona. Kulo mkhiqizo, siwupakisha ngekesi le-3535 Blue SMD LED bese sikhiqiza nge-chip yamandla aphezulu. Ungakwazi ukwenza kalula lokhu kukhanya ngokusebenza kwamanje okuncane. Ngasikhathi sinye, lapho udinga ukukhanya okuphezulu kakhulu noma okukhiphayo, vele ukhululeke ukwandisa okwamanje, ingaphatha i-700mA yamanje futhi ikhiphe ama-50-70lm ngaleso sikhathi.

Ukube ubufuna i-LED enamandla amakhulu ngombala oluhlaza okwesibhakabhaka, lena ngeke ikuyeke ~

Usayizi we-3535 Blue SMD LED:

Amapharamitha kagesi:

* Ukudonswa phambili kwenkomfa yamanje: Umsebenzi ongu-1% nobubanzi bePulse = 10us.

* Umhlangano weSoldering: Umhlangano weSoldering kufanele uqedwe ngamasekhondi ama-3 ku-260 ℃

* Amandla we-Luminous alinganiswa yi-ZWL600.

* I-λD itholakala kumdwebo we-CIE chromaticity futhi imelela ubude obude obuchaza umbala wedivayisi.

Ukuze uqiniseke ukuthi wonke amakhasimende ethu angathola ukusebenza okuphelele kusuka kule 480nm LED enecala lamandla amakhulu le-3535, sikhiqiza le LED yamandla aphakeme enezinhlamvu ezintsha ezizinzile, ifreyimu ye-caremic LED, i-epoxy yekhwalithi ephezulu yelensi kanye nocingo lwegolide olumsulwa uxhumano lwangaphakathi.

UKUPHATHA IZINYATHELO:

Qhathanisa ne-epoxy encapsulant eqinile futhi eqinile, i-silicone ithambile futhi iyaguquguquka i-Althouth i-characteristiec yayo inciphisa kakhulu ukucindezela okushisayo, isengozini enkulu yokonakaliswa ngamandla amakhulu womshini. Ngenxa yalokhu, izindlela zokuphatha ezikhethekile zidinga ukubonwa ngesikhathi sokuhlangana usebenzisa imikhiqizo yeLed silicone efakwe ngaphakathi. Ukwehluleka ukuthobela kungaholela ekulimaleni nasekuhlulekeni kwangaphambi kwesikhathi kwe-led

1. Phatha into eceleni kwezindawo eziseceleni usebenzisa i-forceps noma amathuluzi afanele.

2, Ungathinti ngqo noma uphathe ubuso belensi abicah. Kungalimaza izifunda zangaphakathi.

I-3, Ungafaki ndawonye ama-PCBS ahlanganisiwe aqukethe ama-LED aveziwe. Umthelela ungaklwebha amalensi abicah noma ulimaze ukujikeleza kwangaphakathi.

4, 4-A Ububanzi obungaphakathi kumbhobho wombhobho weSMD akumele budlule ubukhulu be-LED ukuvimbela ukuvuza komoya;

Kuphakanyiswa impahla ephathekayo engu-4-BA yethiphu lombhobho ukugwema ukubambana noma ukulimaza ubuso be-LED ngesikhathi sokuthatha iveni.

4-C Ubukhulu besakhi kufanele buhlelwe ngokunembile emshinini wokukhetha nokubeka indawo ukuze kuqinisekiswe ukuthathwa okuqondile futhi kugweme ukulimala ngesikhathi sokukhiqizwa;

4-D Njengoba ukufakwa kwe-silicone kufakwa amagesi, ezinye izinto ezonakalisayo njenge-H2S zingahle zonakalise i-plationg yesiliva ye-leadframe. Ukunakekelwa okukhethekile kufanele kuthathwe uma kusetshenziswa i-LED ene-silicone encapsulation eduze kwezinto ezinjalo.

5, Sicela i-aviod iqhubeke nokuchayeka emswakama oshisayo futhi ugcine umkhiqizo kude nokushintshwa kokubuyisa ekushiseni kwe-ambiemt.

6, Umkhiqizo kwiphakheji yokuqala evaliwe unconywa ukuthi uhlangane phakathi kwamahora angama-24 wokuvulwa.
