Mayankho a LED akutali komanso osadzipatula

Mayankho akutali komanso osadzipatula a LED aliyense ali ndi mawonekedwe awoawo komanso mawonekedwe ogwiritsira ntchito muukadaulo wowunikira wa LED.Pano pali kusanthula kwatsatanetsatane kwa zosankha zonse ziwiri:

1. Njira yokhayokha ya LED

A. Tanthauzo ndi makhalidwe

Kupatula magetsi:Mbali yaikulu ya njira yokhayokha ya LED ndi kudzipatula kwamagetsi pakati pa zolowetsa ndi zotuluka. Kudzipatula kumeneku kungapezeke kudzera mu thiransifoma kapena zigawo zina zodzipatula, potero kuchepetsa kwambiri kusokoneza kwa phokoso lamagetsi chifukwa cha kukhudzana kwachindunji ndi kuwonongeka kwa zigawo zozungulira zomwe zimayambitsidwa ndi zinthu zoipa monga kugunda kwa mphezi panthawi yotumiza chizindikiro, kukonza chitetezo ndi kudalirika kwa zida.

Chitetezo:Chifukwa cha kukhalapo kwa kudzipatula kwa magetsi, njira yokhayokha ya LED ili ndi ubwino waukulu pachitetezo, chomwe chingalepheretse kuopsa kwa magetsi ndikuteteza chitetezo cha ogwiritsa ntchito ndi zipangizo.

B. Common circuit topology

Mitundu yodziwika bwino yodzipatula ya LED imaphatikizira magetsi obwerera kumbuyo, magetsi osinthika, magetsi osinthira okha, zosinthira zam'mbali zachiwiri, zolandila zakutsogolo, zowongolera mphamvu zosakanizidwa, ndi zina zambiri.
Iliyonse mwa ma topology awa ali ndi mawonekedwe ake, koma zomwe ali nazo ndikuti onse amakwaniritsa kudzipatula kwamagetsi pakati pa zolowetsa ndi zotulutsa.

C. Zochitika zogwiritsira ntchito
Mayankho a Isolated LED nthawi zambiri amagwiritsidwa ntchito pazifukwa zotetezedwa kwambiri, monga magetsi opangira magetsi amtundu wa LED ndi ntchito zamafakitale zomwe zimafuna kudzipatula kwamagetsi.

D. Milandu yofunsira

2. Njira yosagwirizana ndi LED

A. Tanthauzo ndi makhalidwe

Palibe kudzipatula kwamagetsi:Mayankho a LED osadzipatula alibe magetsi olekanitsa pakati pa zolowetsa ndi zotulutsa. Njira yothetsera vutoli nthawi zambiri imakhala ndi dongosolo losavuta la dera komanso kutembenuka kwapamwamba, koma ikagwiritsidwa ntchito, ndikofunikira kuonetsetsa kuti pali mtunda wodzipatula pakati pa mapeto olowera ndi mapeto otuluka kapena kutenga njira zina zotetezera kuti zitsimikizire chitetezo cha zida ndi ogwira ntchito.

Mtengo ndi mphamvu:Chifukwa cha mawonekedwe osavuta ozungulira, njira yosadzipatula ya LED ili ndi zabwino zina pamtengo. Panthawi imodzimodziyo, kutembenuka kwake kumakhala kokwera kwambiri, komwe kumapindulitsa kupulumutsa mphamvu ndi kuchepetsa mtengo.

B. Common circuit topology

Ma topologies wamba omwe sali olekanitsidwa a LED amaphatikiza kuyendetsa molunjika, magetsi angapo, magetsi ogawa magetsi, ndi zina zambiri. Ma topology awa ndi osavuta komanso oyenera kugwiritsa ntchito ndi mtengo wokwera komanso zofunikira za malo.

C. Zochitika zogwiritsira ntchito

Mayankho a LED osadzipatula nthawi zambiri amagwiritsidwa ntchito m'malo omwe ali ndi zofunikira zochepa zachitetezo komanso zofunikira pamtengo ndi malo, monga nyali zing'onozing'ono monga machubu a fulorosenti ya LED.

D.Osadzipatula

3. Kuyerekeza kusanthula

Mwachidule, mayankho a LED odzipatula komanso osadzipatula aliyense ali ndi ubwino ndi zovuta zake, ndipo ayenera kusankhidwa malinga ndi zosowa ndi zochitika zina zomwe zimagwiritsidwa ntchito. Ndi kupita patsogolo kwa teknoloji ndi kuchepetsa ndalama, njira ziwirizi zikuyembekezeredwa kugwiritsidwa ntchito ndikupangidwa m'madera ambiri mtsogolomu.

Ndife opanga okhazikika pakupanga zosinthira ma frequency apamwamba komanso otsika, ma inductors, maginito cores, ndi magetsi oyendetsa ma driver a LED.

Takulandirani kudzachezatsamba mankhwalakugula.
