Ilensi eyi-Super Bright 3mm Blue LED Blue diffused

I-3mm Blue Through-hole LED ene-lens engama-40 degree eluhlaza okwesibhakabhaka:

Le 304BD46D2L12 yi-LED eluhlaza okwesibhakabhaka enelensi eluhlaza okwesibhakabhaka. Njengoba sibona esithombeni, lo mbala welensi ubukeka njengolukhanyayo lwamanzi aluhlaza okwesibhakabhaka hhayi oluhlaza okwesibhakabhaka okujulile. Vele, uma udinga ilensi ejiyile eluhlaza okwesibhakabhaka ejulile yale 460nm - 470nm LED zizwe ukhululekile ukusazisa ~ Singakukhiqizela yona. Ngakolunye uhlangothi, ngesikhathi sokukhiqiza, siphinde sikhiqize le-blue through-hole LED enama-angle angama-40 degree wokubuka, angaqinisekisa ukuthi angakhanyisa indawo ethe xaxa. Nge-angle yokubuka, ama-20 degree 30 degree, 40 degree, 60 degree noma 90 dgree konke kuyatholakala. I-engeli yokubuka ehlukile izokhipha indawo yokukhanya ehlukile, ibanga elincane ngokwengeziwe, indawo encane yokukhanya nebanga elide lokukhanyisa. Uma udinga enye yale LED eluhlaza okwesibhakabhaka ngephrojekthi yakho yokukhanyisa, vele uxhumane nathi ukuthola eminye imininingwane ngayo ~

I-3mm Blue LED eneblue lens ehlukaniswe ngosayizi:

Okwenziwe nge-blue through-hole LED:

Isicelo:

Isifihla-buso se-LED yobuhle;

Ukukhanya kwe-LED emuva;

Inqubekela phambili yokukhiqiza ye-through-hole LED:

Qhathanisa ne-SMD LED, ukukhiqizwa kwe-through-hole kwe-LED kuzoba nzima kakhulu. Okusho ukuthi kuzothatha inqubekelaphambili yokukhiqiza nesikhathi sokukhiqiza:

Okokuqala, sidinga ukulungisa i-chip ye-LED (lokhu kuzofana nokukhiqizwa kwe-SMD LED ); Okwesibili, kuzodingeka ukuthi sibeke i-chip ye-LED ohlakeni lwe-LED, bese sizodinga intambo yegolide emsulwa yokuxhuma i-cathode ne-anode yohlaka lwe-LED. Kufika okwehlukile, Kokukhiqizwa kwe-SMD LED, sidinga ukubeka i-epoxy kuzimele ze-LED bese silinda ize yome ngehhavini. Kodwa-ke, kumalambu e-LED, sidinga ukufaka i-epoxy esikhunjeni selensi bese sibeka zonke izinto kuhhavini okungenani amahora ayi-8 zize zome. Ngemuva kwalokho, sidinga ukubasusa kuhhavini bese sikhipha i-LED kwisikhunta. Futhi-ke sidinga ukusika izikhonkwane ze-LED ukuze kube lula ukuzihlola.

Ekugcineni, sayithola i-LED. Ukuze uqiniseke ukuthi ikhwalithi kanye nomfaniswano kuhle njengoba kudingeka. Sidinga nokubeka wonke ama-LED emshinini wokwehlukanisa futhi sizothola i-LED ngemigqomo efanayo.

Izimo Zokugcina:

1. gwema ukuvezwa okuqhubekayo endaweni efingqa umswakama futhi ugcine umkhiqizo kude nezinguquko ezisheshayo emazingeni okushisa ambient;

2. Ama-LED kufanele agcinwe ngokushisa ≤30 ℃ nomswakama ohlobene <60% ℃;

3. Umkhiqizo okwiphakheji yokuqala evaliwe unconywa ukuthi uhlangane kungakapheli amahora angama-72 wokuvulwa;

4. Umkhiqizo okwiphakheji evuliwe isikhathi esingaphezu kwesonto kufanele ubhakwe amahora we-6-8 ku-85-10 ℃;

INDLELA YOKUKhupHA I-LED

I-1, Iphimbo eliholayo le-LED kufanele lifane nephimbo lezimbobo ezikhuphukayo ku-PCB ngesikhathi sokubekwa kwengxenye;

Ukwenziwa komthofu kungadingeka ukuvikela inkundla yokuhola ifana nephimbo lomgodi;

Bheka isibalo esingezansi ukuthola izinqubo ezifanele zokwenza umthofu;

Ungahambisi umkhondo we-PCB endaweni yokuxhumana phakathi kwegama lokuhola ne-PCB ukuvikela ama-circuits amafushane;

Kuphawulwe:

Method Indlela yokukhweza efanele;

× Indlela yokufaka engalungile;

2. Lapho izintambo ze-soldering ziya kwi-LED, ilunga ngalinye lezintambo kufanele lifakwe ngokwehlukana ngethambo lokunciphisa ukushisa ukuvimbela ukuthintana kwesikhashana.

Ungazihlanganisi zombili izintambo kushubhu eyodwa yokunciphisa ukushisa ukuze ugweme ukuncinza umkhondo we-LED;

Ukuncina ukucindezela kumthofu oholile kungalimaza izakhiwo zangaphakathi futhi kudale ukwehluleka;

Kuphawulwe:

Method Indlela yokukhweza efanele;

× Indlela yokufaka engalungile;

3. Sebenzisa ama-stand-offs (u-Fig 3) noma ama-spacers (Umdwebo 4) ukubeka kahle i-LED ngaphezu kwe-PCB;

4. Gcina ubuncane bokususwa okungu-3mm phakathi kwesisekelo selensi ye-LED nokugoba kokuqala kokuhola (Umdwebo 5. Umdwebo 6)

5. Ngesikhathi sokwakhiwa komthofu, sebenzisa amathuluzi noma ama-jig ukubamba imikhondo ngokuphepha ukuze amandla okugoba angadluliselwa kwilensi ye-LED kanye nezinhlaka zayo zangaphakathi;

Ungenzi ukuhola okwenziwe lapho ingxenye isifakwe ku-PCB;

L Fundza Owenza Izinqubo

1. Izinqubo Zokwenza Abaholi;

2. Ungagoqi imikhondo ngaphezu kokuphindwe kabili (umdwebo 7);

3. Ngesikhathi sokufaka i-soldering, izembozo zezingxenye kanye nabaphathi kufanele bashiye imvume ukuze bagweme ukubeka ingcindezi elimazayo ku-LED ngesikhathi sokufaka (i-Fig 8);

4. Ithiphu yensimbi oku-soldering ayisoze yathinta i-lens epoxy;

5. Ama-LED angena emgodini awahambisani nokufaka okokufaka kabusha okufaka kabusha;

6. Uma i-LED izodlula kuma-soldering pass amaningi noma ibhekane nezinye izinqubo lapho ingxenye ingafakwa ekushiseni okukhulu sicela ubuze nge-Best LED ngokuhambisana;
