Ma LED amphamvu kwambiri monga magwero owunikira ali kale paliponse, koma mumadziwa bwanji za ma LED, ndipo zotsatirazi zidzakutengerani kuti mudziwe zambiri za ma LED.
Mawonekedwe a kuwala kwa LED
Ndi kupita patsogolo kofulumira kwa ukadaulo wa LED, zisonyezo zantchito zasintha kwambiri.Makamaka, magwiridwe antchito a ma LED oyera amphamvu kwambiri, omwe ndi omwe amawunikira kwambiri m'badwo wachinayi, asinthidwa kwambiri.Malingana ndi zofunikira zosiyanasiyana zogwiritsira ntchito, mphamvu ya phukusi limodzi imasiyanitsidwa: kuchokera ku 1 ~ 10W mpaka mazana a watts, mazana a watts;Kuchokera pamawonekedwe a kuwala kotulutsa kuwala kwa ma lens a phukusi la LED, zazikuluzikulu ndi izi: mtundu wa Lambertian, mtundu wa kuwala kwa mbali, mtundu wa mapiko a bat, mtundu wokhazikika (kuphatikizana) ndi mitundu ina, ndipo mawonekedwe okhotakhota akuwonetsedwa pachithunzichi.
Pakali pano, mphamvu yamtundu wa LED yoyera ikukula molunjika ku mphamvu imodzi-chip-high mphamvu, koma chifukwa cha zovuta za botolo la kutentha kwa chip, kutentha kwa chipangizo chimodzi champhamvu kwambiri cha LED pogwiritsa ntchito ma CD amitundu yambiri. Ndizovuta, ndipo kuwala kowala kumakhala kocheperako.Pakupanga magetsi amagetsi amphamvu kwambiri a LED, kusankha kwa ma LED amphamvu kwambiri kumafunika kuganizira zinthu zambiri monga mawonekedwe oyambira, kuwala kowala, zofunikira pakuyika, sekondale ndi kapangidwe kapamwamba kagawo kagawidwe ka kuwala, malo ogwiritsira ntchito, malo oziziritsira kutentha, ndi mawonekedwe otulutsa a wowongolera.Chifukwa chake, kuphatikiza ndi zomwe tafotokozazi, komanso kugwiritsa ntchito bwino, njira yayikulu yosankha ma LED mu nyali zamsewu ndi: mphamvu ya LED imodzi ndi pafupifupi 1 watts mpaka ma watts angapo, kutulutsa bwino kwamitundu, kutentha kosasinthasintha kwamtundu, kuwala kokwanira 90. ~ 100 lm/W zinthu zapamwamba kwambiri ndiye chisankho chabwino kwambiri pakupanga.Mu mphamvu ya nyali ya mumsewu, mphamvu yonse yowala yofunikira imapezeka mwa kusakaniza magulu angapo;Pankhani ya mawonekedwe a kuwala, mtundu wa Lambertian, mtundu wa batwing ndi mtundu wa condenser umagwiritsidwa ntchito kwambiri, koma nthawi zambiri sungagwiritsidwe ntchito mwachindunji ku magetsi a mumsewu, uyenera kupyolera mu mapangidwe ogawa kuwala kachiwiri kuti akwaniritse zofunikira zowunikira mumsewu wa makhalidwe otulutsa kuwala.
