I-Far Red IR 1300nm LED 5mm nge-hole-LED

Ubude obude obude be-LED 1300nm ngamalambu we-5mm we-through-hole;

Ngama-chip afanayo, i-IR LED ingaba iphakethe elihlukile nge-SMD LED noma nge-hole hole uhlobo lwe-LED. Le 504IRC-131L ifakwe kuhlobo lwe-5mm ngembobo ye-LED enecala eliyindilinga elicacile le-epoxy. Nge-IR evamile ye-IR, singabona indawo ebomvu ebomvu lapho sikhanyisa i-diode ye-LED. Kepha ukukhanya kwamaza ukukhanya okufiphele, kule-1300nm LED, asikwazi ukubona ukukhanya emehlweni ethu lapho kusebenza. Isiginali kuphela engakhipha lapho isebenza. Ngakho-ke lapho ungaboni ndawo yokukhanyisa, ngicela ungakhathazeki ngekhwalithi, vele usebenzise omunye umshini wokuhlola ukubheka okukhona noma uvule nje ikhamera kuselula yakho, ungahle ubone indawo emfushane (noma epinki) maphakathi nale 1300nm IR LED. Lokho kungaba yisibonakaliso sokusebenza.

Izimo Zokugcina:

1. Gwema ukuvezwa okuqhubekayo endaweni evumelana nomswakama futhi ugcine umkhiqizo usuka kude nezinguquko ezisheshayo ekushiseni okukhona;

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

3. Umkhiqizo ephaketheni lokuqala elivaliwe kunconyelwa ukuthi lihlanganiswe kungakapheli amahora angama-72 okuvulwa;

4. Umkhiqizo kwiphakheji elivuliwe isikhathi esingaphezu kwesonto kufanele ubhokwe amahora angama-6-8 ku-85-10 ℃;

Indlela Yokukhuphuka Kwe-LED

1, ukuhola komholi we-LED kumele kuhambisane nokuphindwa kwezimbobo ezikhuphukayo kwi-PCB ngesikhathi sokubekwa kwengxenye;

Ukuqanjwa kokuhola kungadingeka ukuze kuqinisekiswe ukuthi iphimbo lokuhola lifane ne-hole pitch;

Bhekisa kwisibalo esingezansi ukuze uthole izinqubo ezifanele zokwakha;

Ungahambisanga umkhondo we-PCB endaweni yokuxhumana phakathi kwe-Loveframe ne-PCB ukuvikela ama-short-circu amafushane;

Kuphawuliwe:

○ indlela yokufaka efanele;

× indlela yokufaka engalungile;

2. Lapho izintambo zombumbulu eziholwa ku-LED, i-wire ngayinye ijoyinti kufanele ifakwe ngokuhlukile ngeshubhu elishisayo lokushisa ukuvikela ukuxhumana okufushane kwesizungu.

Musa ukunxuselisa zombili izintambo ku-tube eyodwa yokushisa shrink ukugwema ukuncipha okuholela kwe-LED;

Ukuncipha kwengcindezi ku-Led Lead kungalimaza izakhiwo zangaphakathi futhi kubangele ukwehluleka;

Kuphawuliwe:

○ indlela yokufaka efanele;

× indlela yokufaka engalungile;

3. Sebenzisa ama-Stand-offs (Fig 3) noma ama-spacers (Fig 4) ukubeka ngokuphepha i-LED ngenhla kwe-PCB;

4. Gcina ubuncane bokuvulwa kwe-3mm phakathi kwesisekelo selensi ye-LED kanye ne-bend yokuqala yokuhola (Umdwebo 5. Fig. 6)

5. Ngesikhathi sokuhola ukwakha, sebenzisa amathuluzi noma ama-jigs ukubamba okuphephile ukuze amandla okugoba angadluliselwa kwilensi ye-LED kanye nezinhlaka zangaphakathi zangaphakathi;

Ungenzi ukwakheka kokuhola uma isakhi sifakwe kwi-PCB;

L izinqubo ezakha izinqubo

1. Hola izinqubo zokwakha;

2. Musa ukugoba okuholela ngaphezu kokubili (Fig. 7);

3. Ngesikhathi sokuthengisa, izembozo zezakhi kanye nabanikazi kufanele zishiye imvume ukuze zigweme ukubeka ukucindezela okulimazayo ku-LED ngesikhathi sokuthengisa (Umdwebo 8);

4. Ithiphu yensimbi yokuthengisa ye-soldering akufanele ithinte i-lens epoxy;

5. Ngokuhamba nge-leds-hole ahlukene ayihambelani ne-Reflew Soldering;

6. Uma i-LED izodlula i-soldering eminingi noma ibhekane nezinye izinqubo lapho ingxenye ingahle ibekwe khona ekushiseni okukhulu sicela uhlole nge-LED engcono kakhulu yokuhambisana;
