Ngaba izibane ze-LED zinokusikwa?

Inokunqunyulwa. Isiphaluka somtya wokukhanya we-LED wenzelwe ngochungechunge / uxhulumaniso oluhambelanayo, kodwa imigaqo yendlela enokuthi inqunywe ngayo iyahluka. Oku kuxhomekeke kuyilo lwesibane sokukhanya kwe-LED. Ngokuqhelekileyo, abavelisi bemigca yokukhanya ye-LED bavelisa izibane ze-LED. Xa kuziwa kwimicu, banemigaqo yesekethe yokulungelelanisa imichilo ye-LED ngokweemfuno. Izibane ze-LED zikwasetyenziswa ngokweemfuno. Izibane ze-LED zinemida yombane osebenzayo ohlukeneyo, ngoko ke izibane ze-LED zisekelwe kumbane weentsimbi zesibane ezisetyenzisiweyo. Eyahlukileyo, indawo yokusika nayo iya kwahluka.

Umzekelo 1: I-12-volt izibane ze-LED zikholisa ukuza kwiinkcukacha ezimbini, kunye nesibane esinye kunye nokusikwa esinye, okanye izibane ezithathu kunye nokusikwa okunye.

1. Okokuqala, siya kwazisa isibane esinye-indlela yokusika enye. Isebenzisa i-9-volt yesibane sesibane esisebenzayo. Ngale ndlela, isibane sesibane se-9-volt kunye ne-resistor sinokudibaniswa kwi-series ukunciphisa i-voltage, kwaye enye i-lamp-one cut inokufezekiswa.
2. Oko kukuthi, ukunqumla izibane ezithathu ngaxeshanye. Usebenzisa amaso ezibane ezi-3 zevolthi. Ezi zibane zintathu zixhunyiwe kwi-series kunye ne-resistor ukunciphisa i-voltage, ukwenzela ukuba izibane ezithathu zinokunqunyulwa kwindawo enye.

Umzekelo 2: Zininzi izinto ezichaziweyo ze-24-volt zemigca yokukhanya ye-LED. Izikhundla apho i-24-volt ye-LED imicu yokukhanya inokunqunyulwa kwimarike inokukumangalisa. Izibane ze-LED ze-24-volt ziquka isibane esisodwa-enye-inqumle, izibane ezimbini-enye-i-cut, kunye nezibane ezintathu-enye-cut. Sika, izibane ezithandathu kunye nokusikwa esinye, kunye nezibane ezisixhenxe kunye nokusikwa okunye.

1. Ukusebenza okukodwa kwesibane esisodwa. Isebenzisa i-18V ukuya kwi-21V i-voltage ye-voltage esebenzayo amaso kunye nezichasi eziqhagamshelwe kuthotho ukunciphisa amandla ombane. Oku kunokufezekisa ukusebenza kwesibane esinye-off.
2. Uzenza njani izibane ezibini kunye nomgca omnye osikiweyo we-LED? Usebenzisa amaso e-voltage amabini e-9-volt asebenzayo kunye ne-resistors edityaniswe kwi-series ukunciphisa i-voltage, ukwenzela ukuba isibane esinezibane ezibini kunye noyilo lokusika olunye lunokufezekiswa.
3. Uzenza njani izibane ezithathu kunye nomgca omnye osikiweyo we-LED? Usebenzisa izibane ezintathu zesibane kunye ne-voltage esebenzayo ye-volts ye-6 kwaye idibanisa kwi-series kunye ne-resistors ukunciphisa i-voltage, ukwenzela ukuba i-design-lamp-one-cut-cut design inokufezekiswa.
4. Isibane se-LED esinezibane ezithandathu-enye-esikiweyo isebenzisa amaso amathandathu ane-3-volt yesibane. Amaso amathandathu isibane kunye resistors ziqhagamshelwe kuthotho ukunciphisa i-voltage, ukuze isibane ezintathu-ukusika uyilo enye inokufezekiswa.
5. Kuthekani ngesibane esisixhenxe nesisikwe esinye? Isibane se-LED esinezibane ezisixhenxe-enye-esikiweyo iqulethe iintsimbi ezisixhenxe ze-3-volt kunye ne-resistors ezidityaniswe kuluhlu, ukwenzela ukuba i-design ye-seven-cut-cut-cut design inokufezekiswa.

Enyanisweni, imichilo yokukhanya ye-LED iya kuphawulwa ekuqaleni koyilo. Umtya ngamnye wezibane uya kuba nomgca othe ngqo apho unokunqunyulwa khona. Kufuneka kuphela ukuyisika kule ndawo. Ukuba indawo yokusika ayikho kumgca othe ngqo, iya kubangela ukuba isethi yezibane ze-LED zinqunywe. Akukho meko yokukhanya.

Apha ngezantsi ndiza kukubonisa iifoto zeemveliso zenkampani yethu ukukunceda uchonge iindawo zokusika zemigca yokukhanya ye-LED.

Izilumkiso zokusikwa

1. Xa usika izibane ze-LED, nceda uqaphele ukuba kufuneka zinqunywe ngokuthe nkqo.
2. Nikelani ingqalelo ekusikeni okwahlukeneyo kweepleyiti zomtya wokukhanya we-LED. Ukuze kuhlangatyezwane ne-thermal conductivity kunye nokusebenza kokutshatyalaliswa kobushushu kwiintambo zokukhanya kwe-LED, ezininzi iintambo zokukhanya kwe-LED ngoku zisebenzisa i-aluminium substrates. I-Aluminiyam substrates iyaqhuba. Xa ucheba, Kunokwenzeka kakhulu ukuba kubangele isiphaluka esifutshane, ngoko kufuneka sihlolisise ukuba i-foil yobhedu idityaniswe ne-aluminium substrate engezantsi emva kokusika. Ukuba amakhonkco axhunyiwe, kufuneka sizahlule ukukhanyisa ukukhanya kwe-LED.
