Ukukhanya okude kwe-IR 1300nm i-LED ye-5mm nge-hole-LED

Ubomvu obomvu obude be-1300nm ubude kunye ne-5mm nge-hole-LED;

Kwiichips ezifanayo, i-IR ye-IR inokuba yiphakheji eyahlukeneyo ene-SMD ye-LED okanye ngohlobo lwe-LED yangaphakathi. Le 504IRC-131L ifakwe ngaphakathi kwi-5mm ngohlobo lwemingxunya ye-LED enemeko ejikeleze ecacileyo ye-epoxy. Kwi-IR eqhelekileyo ye-IR, sinokubona indawo ebomvu ebomvu xa sikhanyisa i-diode ye-LED. Kodwa ukukhanya kwamaza ngakumbi kukukhanya okuqaqambileyo, kule 1300nm ye-LED, asinakubona nakuphi na ukukhanya emehlweni ethu xa sisebenza. Ngumqondiso kuphela onokuthi ukhuphe xa usebenza. Ke xa ungaboni ndawo yokukhanyisa, nceda ungakhathazeki malunga nomgangatho, sebenzisa nje omnye umatshini wovavanyo ukujonga okwangoku okanye uvule ikhamera kwiselfowuni, ungabona umbala omfusa (okanye opinki) embindini wale 1300nm IR LED. Oko kunokuba ngumqondiso wokusebenza.

Iimeko zokugcina:

1. Kulumkele ukuveza ukuqhubeka kwendawo yokufumanisa umswakama kwaye ugcine imveliso ikude kwimveliso ekhawulezileyo kumaqondo obushushu aphantsi;

2. I-LEDS kufuneka igcinwe ngamaqondo obushushu ≤30 ℃ kunye nokufuma okuhambelana <60% ℃;

3. Imveliso kwiphakheji etywiniweyo yoqobo iyacetyiswa ukuba ihlanganiselwe kwiiyure ezingama-72 zokuvula;

4. Imveliso kwipakethi evuliweyo ngaphezulu kweveki kufuneka ibhakwe iiyure eziyi-6-8 nge-85-10 ℃;

Indlela yokunyuka ye-LED ye-LED

1, Isigqubuthelo esikhokelayo se-LED kufuneka sihambelane ne-pitch yemingxunya yokunyuka kwi-PCB ngexesha lokubekwa kwecandelo;

Ukuqulunqwa kwe-Comman kunokucelwa ukuba inyanzelise i-pitch ekhokelayo ihambelana ne-Hitch yeHit;

Bhekisa kumzobo ongezantsi kwinkqubo efanelekileyo yokwenza;

SUKUKHO nto i-PCB TRACE kwindawo yoqhakamshelwano phakathi kweNqweno kunye nePCB ukukhusela isekethe elifutshane;

Iqatshelwe:

Indlela efanelekileyo yokunyuka;

Indlela yokunyuka engalunganga;

2. Xa i-wimi ethengiswayo kwi-LED, i-wire nganye yocingo kufuneka ifakwe ngokwahlukeneyo ityhubhu yokutshiswa kobushushu ukuthintela unxibelelwano lwesekethe olufutshane.

Sukuthintela iingcingo zombini kubushushu obunye obushushu ukunqanda ukuthoba isikhokelo se-LED;

Ukutyhila uxinzelelo kwizifundo ze-LED kunokulimaza izakhiwo zangaphakathi kwaye zibangele ukusilela;

Iqatshelwe:

Indlela efanelekileyo yokunyuka;

Indlela yokunyuka engalunganga;

3. Sebenzisa i-STA-OFFS (FIG 3) okanye iiSpacer (Fig 4) ukukhusela i-LED engaphezulu kwePCB;

4. Gcina ubuncinci ukucocwa kwe-3mm phakathi kwesiseko se-lens ye-LED kunye ne-Comple Town Bind (Fig. 5. Umzobo 6)

5. Ngexesha lokwakha, ukusebenzisa izixhobo okanye i-jigs ukubamba izizathu zikhokelela ngokukhuselekileyo ukuze amandla okuhlamba akasayi kudluliselwa kwilensi ye-LED kunye nezakhiwo zayo zangaphakathi;

Sukwenza ukwenziwa kokukhokelela xa icandelo libekwe kwi-PCB;

Iinkqubo zokwenza i-EAD

1. INKCAZO YOKUQHUTYELWA YOKUGQIBELA;

2. Musa ukugoba okukhokelela ngaphezulu kwe (Fig. 7);

3. Ngexesha lokuthengiswa, umbutho ogubungelweyo kunye nabanini manini mabaphume ekuvumeni ukunqanda ukubeka uxinzelelo kwi-LED ngexesha elisemthethweni (Fig 8);

4. Inzuzo yentsimbi engekhoyo akufuneki ichukumise i-appoxy yelensi;

5. Ngokusebenzisa i-LED-hole ayihambelani nokuthengiswa okuvunileyo;

6. Ukuba i-LED iya kuqhubeka idluliselwe kwi-tsods ezininzi okanye ijonge ezinye iinkqubo apho inxenye inokuthi ifakwe khona ubushushu obukhulu nceda jonga ngokuhambelana;
