5mm I-LED Ebomvu 12V 20mA I-Resistor Ehlanganisiwe

12V 5mm LED nge ngokusebenzisa-imbobo Uhlobo

503FRD62D3L14-12V ithole ezibekiweko efanayo ne 304FRD62D3L14V12. Ngoba kokubili lokhu Red Through-imbobo LED, bonke bangabafowabo obomvu lens okusabalele kanye 12V voltage phambili, 20mA ukusebenza wamanje kanye ihlanganiswe Resistor ngaphakathi. I ezahlukene ezinkulu silingana LED Izibani. Lo mqeqeshi owake wapheka 5mm Red Through-imbobo LED ithole ubukhulu 5mm Red udlulele isilinda nge 8.7mm okusezingeni eliphezulu kanye 3mm yokugcina Red Through-imbobo LED Usanda 3mm ubukhulu osasitini lens epoxy. Kulokhu, 5mm 12V LED 620 - 625nm LED ngeke ithole endaweni ezinkulu likhipha. Ingabe udinga eminye LED 12V phrojekthi yakho? Thintana nathi for kabanzi noma uma udinga ezinye isampula test ~

Usayizi 12V 5mm LED:

* Isibani senkomba;

* Isibani sokuhlobisa se-LED;

Imininingwane Yomkhiqizo:

99.99% yocingo lwegolide oluhlanzekile;

Uhlaka lwe-LED olufakwe ngesiliva;

Ama-chips adumile;

Ikhwalithi ephezulu ye-epoxy;

Inqubekelaphambili yokukhiqiza ye-LED ye- through-hole:

Qhathanisa ne-SMD LED, ukukhiqizwa kwe-LED ngembobo kuzoba nzima kakhulu. Yikuphi izindlela kuzothatha ngaphezulu intuthuko ukukhiqizwa nesikhathi ukukhiqizwa:

Okokuqala, kudingeka silungiselele chip LED (lokhu kuzoba efanayo ukukhiqizwa SMD LED); Okwesibili, sizodinga ukufaka i-chip ye-LED ohlakeni lwe-LED, bese sizodinga ucingo oluhlanzekile lwegolide ukuxhuma i-cathode ne-anode yohlaka lwe-LED. Kuza okuhlukile, Ngokukhiqizwa kwe-SMD LED, sidinga ukubeka i-epoxy kuhlaka lwe-LED bese silinda ize yome kuhhavini. Kodwa-ke, kumalambu e-LED, sidinga ukujova i-epoxy esibunjeni se-lens futhi sibeke zonke izinto kuhhavini okungenani amahora angu-8 zize zome. Ngemuva kwalokho, sidinga ukuwakhipha kuhhavini futhi sikhiphe i-LED ekubunjweni. Futhi-ke sidinga ukusika izikhonkwane ze-LED ukuze zibe lula ukuhlola.

Ekugcineni, sathola i-LED. Ukuze uqiniseke ukuthi ikhwalithi kanye neyunifomu kuhle njengoba kudingeka. Sidinga futhi ukubeka wonke ama-LED emshinini wokuhlukanisa futhi sizothola i-LED enemigqomo efanayo.

Isitoreji Izimo:

1. Gwema baqhubeka ukuchayeka ushintsha uba yileli umswakama imvelo bese ugcine umkhiqizo kude ukuhwebelana okusheshayo e ezingeni lokushisa elifanele;

2. LED kufanele agcinwe nge lokushisa ≤30 ℃ kanye nomswakama isihlobo <60% ℃;

3. uMkhiqizo iphakethe yasekuqaleni uphawu Kunconywa uhlanganiswe emahoreni anga-72 ukuvulwa;

4. uMkhiqizo iphakethe wavula isikhathi esingaphezu kwesonto kufanele wabhaka amahora 6-8 at 85-10 ℃;

LED INDLELA obandayo

1, The iphimbo lea d wasekhaya kumele ifane iphimbo we izimbobo ukugibela PCB ngesikhathi ukubekwa ingxenye;

Hola-ukwakha kungahle kudingeke ukuthathelwa umshuwalense phambili iphimbo elifana iphimbo imbobo;

Bheka sibalo ngezansi ukuze phambili ukwakha imigudu efanele;

Ungavuli umzila PCB trace endaweni ukuxhumana phakathi leadframe kanye PCB ukuvimbela esifushane izifunda;

waphawula:

○ Lungisa indlela obandayo;

× engalungile indlela obandayo;

2. Lapho izintambo nokunamathisela ngomthofu kuya LED, wire ngamunye ngokuhlanganyela kumele eceleni luphahlekwa ukushisa-Nciphisa tube ukuvimbela isekhethi contact.

Musa zihlanganisa kokubili izintambo e ukushisa eyodwa Nciphisa tube ukugwema pinching imikhondo LED;

Pinching ukucindezeleka phezu imikhondo kwaholela kungalimaza izakhiwo yangaphakathi kanye imbangela ukwehluleka;

waphawula:

○ Lungisa indlela obandayo;

× engalungile indlela obandayo;

3. Sebenzisa ukuma-offs (Fig 3) noma spacers (Fig 4) isikhundla ngokuphephile LED ngaphezu PCB;

4. Gcina ubuncane 3mm cl earance phakathi kumila lens LED nomthofu kuqala bend (Fig. 5. Fig. 6)

5. Ngesikhathi phambili ukwakha, ukusebenzisa amathuluzi noma jigs ukubamba imikhondo ngokuphephile ukuze amandla eguqa ngeke yadluliselwa lens LED kanye nezinhlaka zayo zangaphakathi;

Musa ukwenza phambili ukwakha kanye ingxenye bekulokhu ukukhwezwa ungene PCB;

L Fundza Owenza Izinqubo

1. Hola Owenza Izinqubo;

2. Musa agobe imikhondo ezingaphezu kuka kabili (Fig 7.);

3. Ngesikhathi nokunamathisela ngomthofu, izembozo ingxenye nemicengezi kufanele ashiye imvume ukuze agweme ukukufaka kokulimaza ukucindezeleka phezu LED ngesikhathi nokunamathisela ngomthofu (Fig 8);

4. Isihloko insimbi nokunamathisela ngomthofu akufanele neze uthinte epoxy lens;

5. Esebenzisa-imbobo LED s azihambelani nokunamathisela ngomthofu ukugelelza;

6. Uma LED uzohanjiswa amaningi nokunamathisela ngomthofu maqembu noma ubuso nezinye izinqubo lapho kungenzeka ingxenye ngaphansi ngenxa yokushisa okukhulu sicela uhlole ne Kuhle LED kungasebenziswa;
