I-12V 3mm I-LED Eluhlaza Esakhelwe ngaphakathi Isimelaphi DC

12 Volt Blue Through-imbobo LED nge Blue okusabalele LED

Common blue SMD LED noma okwesibhakabhaka throuhg-imbobo LED ngeke Usanda voltage phambili e 3V. Ukuze umsebenzi LED ngaphezulu esigculisayo 12V voltage. Lokhu 304BD465D2L12V12 3mm Blue Through-imbobo LED wayithi Resistor ihlanganiswe lapho singaqinisekisa LED ukuba ezixhunywe ngokuqondile supply 12V amandla. Qhathanisa ngoku-wire 12V LED, lokhu Izibani LED kuyoba ezinzima ngaphezulu, okuthembekile

Dimension 3mm ngokusebenzisa-imbobo LED:

Amapharamitha kagesi:

* Isimo samanje se-Pulse forward: Umsebenzi ongu-1% nobubanzi be-pulse=10us.

* Isimo sokudambisa: Isimo sokudambisa kufanele sigcwaliswe nge-3 secongds ku-260 ℃

Electrucal Izici Optical (TC = 25 ℃)

*I-Luminous Intensity ikalwa nge-ZWL600.

*θ1/2 iyi-engeli ye-off-sxis lapho ubungako obukhanyayo buyingxenye yokuqina kwe-axia elikhanyayo;

Isicelo Main:

* Vehicle nokugqamisa ukukhanyisa;

* Wendlovu ukukhanya;

* Enigine ukukhanyisa;

* Motorcycle nokugqamisa ukukhanyisa;

Imininingwane Yomkhiqizo:

99.99% yocingo lwegolide oluhlanzekile;

Isiliva kuhlinzwa Uhlaka LED;

Ama-chips adumile;

High izinga epoxy;

Ukwenza inqubekela phambili ngokusebenzisa-imbobo LED:

Qhathanisa SMD LED, ngokusebenzisa-imbobo ukukhiqizwa LED uzobe ngaphezulu inkimbinkimbi. Yikuphi izindlela kuzothatha ngaphezulu intuthuko ukukhiqizwa nesikhathi ukukhiqizwa:

Okokuqala, kudingeka silungiselele chip LED (lokhu kuzoba efanayo ukukhiqizwa SMD LED); Okwesibili, sizodinga ukubeka chip LED ku ifreyimu LED, bese sizodinga igolide wire okumsulwa ukuxhuma cathode futhi anode Uhlaka LED. Kufika ezahlukene, Ukuze ukukhiqizwa SMD LED, kudingeka ubeke epoxy ukuze uzimele LED bese ulinda kuze kube ome ngu kuhhavini. Nokho, i-LED Izibani, kudingeka bafake epoxy ku isikhunta lens futhi abeke zonke izinto kuhhavini okungenani amahora angu-8 aze ome. Ngemva kwalokho, kudingeka Tae kubo kuhovini uthole LED out nezingozi zesikhunta. Bese okudinga ukuqedwa izikhonkwane LED ukuze bakwazi kube lula ukuhlolwa.

Ekugcineni, sifika LED. Ukuze uqiniseke ukuthi izinga kanye iyunifomu kwafana edingekayo. Kudingeka futhi wafaka yonke LED kumshini ngokwahlukana kwabo sizobe got LED nge imigqomo 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;
