I-12V 3mm iGreen iGreen IPRED-KWI-DC

I-12 volt ikhokelele nge-12v 3mm nge-3v-Hole yakhokelela kwi-LED eluhlaza

Kukho indlela emibini yokuvelisa ukukhanya kwe-12v Diode, owokuqala ukwi-wangare yangaphambi kokurhoxa kwisikhokelo se-led. Oko kuthetha ukuba, ngalo lonke ixesha sigqibile ukuveliswa kwezibane ezikhokelweyo, kufuneka sigqibe ukuphinda-phinda i-mini (malunga ne-1mm) kumlenze we-LED ukuze ikwazi ukuqinisekisa ukuba lo msebenzi ukhokelekileyo uzinzile kwi-12v voltage. Kwelinye icala, sinokongeza eyakhiwe kwi-LED, esikunye neChip ye-LED. Le 304LGD52D7L12v12 ifumene ngokulahlela ngaphakathi kwephakheji eluhlaza engasebenziyo, nokuba le yi-3mm eluhlaza ngokuhamba-hamba, i-resitor mincinci ngokwaneleyo ukuba ifakwe ngaphakathi. Ngale ndlela, sisenokungasiboni umphengululi omncinci welensi engaqhelekanga. Kodwa iyasebenza kakuhle kwi-Green Hole-hole ikhokelwa ngaphakathi. Ukuba ufuna i-12v 3mm Green Elm yeProjekthi yakho, zive ukhululekile ukunxibelelana nathi kwaye ufumane iinkcukacha ngakumbi malunga ne-IT ~

Ubungakanani be-3mm eluhlaza kwi-LE-HOLE YENZA:

Iiparamitha zombane:

* I-pulse thumela imeko yangoku: I-DOD 1% kunye nePulses = I-10US.

Iinkcukacha zemveliso:

I-99.99% i-wire yegolide yegolide;

Isakhelo se-LAPRED yeSilivere;

Iitshiphu ezidumileyo;

I-Epoxy ephezulu ye-Epoxy;

Ukwenza inkqubela phambili ye-Edred-Hole:

Thelekisa kunye ne-SMD ekhokelwayo, ngemveliso ye-HoLE ye-HoLE ye-HoLE iya kuba nzima ngakumbi. Oko kuthetha ukuba kuya kuthatha inkqubela phambili yemveliso kunye nexesha lemveliso:

Okokuqala, kufuneka silungiselele i-CHIP ye-LED (iya kufana nemveliso ye-SMD ); Okwesibini, kuya kufuneka sibeke i-chip ye-LED kwisikhephe se-LED, kwaye emva koko siya kufuna intambo yegolide ecocekileyo yokuqhagamshela i-makhode kunye ne-Amode yesakhelo se-LED. Iza ngokwahlukileyo, kwimveliso ye-SMD, kufuneka sibeke isakhelo esikhokelayo kwaye silinde de yome nge-oveni. Nangona kunjalo, kwizibane ezikhokelweyo, kufuneka siyikhuphe i-epoxy kwisifo selensi kwaye sibeke zonke izinto eziya kwi-oven ubuncinci iiyure eziyi-8 de yome. Emva koko, kufuneka sizicinezele kwi-oveni kwaye sifumane ukukhokelwa ngaphandle. Kwaye ke kufuneka sinciphise izikhonkwane ze-LED ukuze zibe lula ukuvavanya.

Ekugqibeleni, sifumene i-LED. Ukuze uqiniseke ukuba umgangatho kunye neyunifomu ilungile njengoko kufuneka. Kufuneka sibeke yonke i-LED kumatshini wokwahlula-hlula kwaye siya kufumana i-LED ngee-bin ezifanayo.

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, iLea D Litch ye-LED kufuneka ihambelane 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 i-3mm ye-3mm ye- COS enesiseko selensi ye-LED kunye ne- Comple ye-Cound (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 . SUKUVULELA INDLELA ENOKUKHUSELEKILEYO NGOKUGQIBILEYO (FIT. 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 umngxunya ovuthuzayo akungqinelani 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 ;
