4 Tekinoloje yofunika pakuwunikira kwa LED
Kusankhidwa ndi kakonzedwe ka LED
Pali mitundu itatu ikuluikulu ya ma LED potengera kapangidwe kake: imodzi ndi lead (lead angle) LED, yomwe idavotera nthawi zambiri imakhala 20 mA, mphamvu ndi yaying'ono, ndipo kulumikizana kofananirako kumafunikira pakuwunikira; ina ndi single-chip pamwamba phiri Chip LED, panopa oveteredwa zambiri kuposa 50 mA (pakali pano pazipita oveteredwa panopa wa LED kufika 1000 mA), mphamvu ndi yaikulu, ndipo angagwiritsidwe ntchito yokha; chachitatu ndikuphatikiza tchipisi tating'onoting'ono tating'ono kuti tikwaniritse mphamvu zambiri, ndiye kuti, kuphatikiza Mphamvu ya LED.
Kugwiritsiridwa ntchito kwa ma LED angapo mofanana kumakhala ndi ndalama zochepa zopangira ndipo ndikoyenera kuunikira kumadera akuluakulu, koma kumafuna dongosolo loyenera. Pogwiritsa ntchito ma diode otsika mphamvu, kuti kuunikira kwa nyali imodzi kukwaniritse zosowa za nkhope ya migodi ya malasha, ma diode angapo ayenera kugwiritsidwa ntchito mofanana. Izi zimabweretsa funso la kuchuluka kwa ma voliyumu omwe amagwiritsidwa ntchito komanso momwe angayendetsere kuchuluka kwa ma diode molingana ndi gulu kuti akwaniritse zofunikira za dera lotetezedwa mkati. Chifukwa voteji ya dera lotetezedwa mwachilengedwe ndi 24, 18, 12 V, ndi zina zotero, mafunde ogwirizana ndi zofunikira zachitetezo chamkati ayenera kukhala 400, 600, ndi 1000 mA. Kwa ma diode wamba otulutsa magetsi ochepera mphamvu, mphamvu yogwirira ntchito nthawi zambiri imakhala 3 mpaka 4 V ndipo yomwe ikugwira ntchito ndi 20 mA. Ngati 18 V / 600 mA yasankhidwa, magulu 30 akhoza kulumikizidwa mofanana, 5 mndandanda ngati gulu, ndiyeno chotsutsa choyenera chimalumikizidwa mndandanda. Kutsika kwamagetsi kwa diode iliyonse kumakhala kosakwana 3.6V, komwe kumakwaniritsa zofunikira zamtundu wotetezedwa komanso kuwala. Pamene imodzi kapena gulu lawonongeka, sizimakhudza ntchito ya ma diode ena kapena kuwala.
Ma LED angapo akalumikizidwa molumikizana, mphamvu ya LED imodzi imakhala yaying'ono ndipo kutentha komwe kumapangidwa kumamwazikana. Malingana ngati ma LED akonzedwa moyenerera ndipo dera la Cu la bolodi losindikizidwa likuwonjezeka, zofunikira zowonongeka zimatha kukwaniritsidwa.
Pamene ma diode amphamvu kwambiri amagwiritsidwa ntchito, kapangidwe ka dera lotetezedwa mwachilengedwe sikhalanso vuto. Chinsinsi ndi momwe mungakonzekere ma diode kuti akwaniritse zosowa za nkhope ya migodi ya malasha.
