Iziseko zokuKhanya kwe-LED

Ziziphi ii-LED kwaye zisebenza njani?

I-LED imele iidiode ekhupha ukukhanya. Iimveliso zokukhanyisa i-LED zivelisa ukukhanya ukuya kwi-90% ngokufanelekileyo ngakumbi kunezibane ze-incandescent. Zisebenza njani? Umsinga wombane udlula kwi-microchip, ekhanyisa imithombo emincinci yokukhanya esiyibiza ngokuba zii-LED kwaye umphumo ubonakala ukukhanya. Ukuthintela imiba yokusebenza, ubushushu be-LED buvelisa bufunxwa kwisitya sobushushu.

Ubomi bonke beUkukhanya kwe-LEDIimveliso

Iubomi obuluncedoiimveliso zokukhanyisa i-LED zichazwa ngokwahlukileyo kunezinye izibane zokukhanya, ezifana ne-incandescent okanye i-compact fluorescent lighting (CFL). Ii-LED ngokuqhelekileyo "azitshi" okanye zisilele. Endaweni yoko, bafumana 'ukuhla kwe-lumen', apho ukuqaqamba kwe-LED kuncipha kancinci ngokuhamba kwexesha. Ngokungafaniyo ne-incandescent bulbs, i-LED "ixesha lokuphila" isekwe kwingqikelelo xa ukukhanya kuncipha ngama-30 ekhulwini.

Ii-LED zisetyenziswa njani ekuKhanyeni

ii-LEDszifakwe kwiibhalbhu kunye nezixhobo zokukhanyisa ngokubanzi. Ubungakanani obuncinci, ii-LED zibonelela ngamathuba oyilo awodwa. Ezinye izisombululo zebhalbhu ze-LED zinokufana ngokwasemzimbeni neeglowubhu eziqhelekileyo kwaye zihambelane ngcono nenkangeleko yebhalbhu zesintu. Ezinye izibane ze-LED zinokuba nee-LED ezakhelwe ngaphakathi njengomthombo wokukhanya osisigxina. Kukwakho neendlela ezixubeneyo apho “ibhalbhu” engeyiyo eyesintu okanye ifomathi yomthombo wokukhanya enokuthathelwa indawo isetyenzisiweyo kwaye iyilelwe ngokukodwa isisitho esisodwa. Ii-LEDs zinika ithuba elikhulu lokuqamba izinto ezintsha kwizinto zokukhanyisa kwaye zilungele ububanzi obubanzi bezicelo kunobuchwepheshe bokukhanyisa bendabuko.

ii-LED kunye nobushushu

Ii-LED zisebenzisa i-heat sinks ukuze zifunxe ubushushu obuveliswa yi-LED kwaye bubuchithe kwindawo engqongileyo. Oku kugcina ii-LEDs ekutshiseni kunye nokutshisa ngaphandle.Ulawulo lobushushungokubanzi yeyona nto ibalulekileyo ekusebenzeni ngempumelelo kwe-LED ebomini bayo. Ukuphakama kweqondo lokushisa apho ii-LED zisebenza khona, ngokukhawuleza ukukhanya kuya kuncipha, kwaye ubomi obuluncedo buya kuba bufutshane.

Iimveliso ze-LED zisebenzisa iindlela ezahlukeneyo zokuyila ubushushu bokushisa kunye noqwalaselo ukulawula ubushushu. Namhlanje, ukuqhubela phambili kwezixhobo kuye kwavumela abavelisi ukuba bayileIibhalbhu ze-LEDezihambelana neemilo kunye nobukhulu beebhalbhu ze-incandescent zakwantu. Kungakhathaliseki ukuyila kobushushu, zonke iimveliso ze-LED ezifumene i-ENERGY STAR ziye zavavanywa ukuze ziqinisekise ukuba zilawula ngokufanelekileyo ubushushu ukuze ukukhanya okukhanyayo kugcinwe ngokufanelekileyo ekupheleni kobomi bayo obulinganisiweyo.
