Indlela ii-LEDs ezichatshazelwa ngayo yi-Cold and Hot Temperatures
Ii-LED zisebenza njani kubushushu obubandayo
Enye yezona zinto zidumileyo zokukhanya kwe-LED kukuba iqhuba kakuhle kumaqondo obushushu aphantsi. Esona sizathu siphambili soku kungenxa yokuba ixhomekeke kwiidrive zombane ukuze zisebenze.
Inyani kukuba ii-LED zikhula kakuhle kumaqondo obushushu aphantsi.
Ekubeni ii-LED ziyimithombo yokukhanya ye-semiconductor, zikhupha ukukhanya xa ikhoyo ngoku ihamba ngayo, ngoko ayichaphazeli ukushisa kwendawo ebandayo kwaye ingavulwa ngokukhawuleza.
Ukongezelela, ngenxa yokuba uxinzelelo lwe-thermal (utshintsho lobushushu) olubekwe kwi-diode kunye nomqhubi omncinci, ii-LED zisebenza kakuhle kumaqondo aphantsi. Enyanisweni, uphando lubonise ukuba xa i-LED ifakwe kwindawo ebandayo, izinga lokuthotywa kwayo liya kuncitshiswa kwaye ukuphuma kwe-lumen kuya kwandiswa.
Isebenza njani i-LED kumaqondo obushushu aphezulu
Xa ii-LED zaqala ukwaziswa kwimarike, zinezindlu zesihlangu kwaye zinokutshisa ngokukhawuleza ngenxa yokungabikho komoya. Ukuthintela oku kungenzeki, abavelisi baye baqala ukufaka abalandeli kwizibane ze-LED, kodwa oku kuya kubangela kuphela ukungaphumeleli komatshini.
Isizukulwana esitsha se-LED sinomtshini wokushisa ukunceda ukuthintela ukuhla kwe-lumen ehambelana nobushushu. Bahambisa ubushushu obugqithisileyo kwaye bazigcine kude nee-LED kunye nabaqhubi. Ezinye izibane zibandakanya imbuyekezo yesekethe elungelelanisa ukuhamba kwangoku kwi-LED ukuqinisekisa ukukhutshwa kokukhanya okuqhubekayo kumaqondo obushushu ahlukeneyo.
Nangona kunjalo, njengezixhobo ezininzi zombane, ii-LED zidla ngokusebenza kakubi xa zisebenza kumaqondo obushushu alindelekileyo. Kwindawo yobushushu obuphezulu bexesha elide, i-LED inokusebenza ngokugqithisileyo, enokunciphisa ixesha lokuphila kwayo (L70). Ubushushu obuphezulu be-ambient buya kubangela ubushushu obuphezulu besiphambuka, okuya kwandisa izinga lokuthotywa kwamacandelo e-junction ye-LED. Oku kubangela ukuba ukukhutshwa kwe-lumen yesibane se-LED kwehle ngokukhawuleza ngesantya esikhawulezayo kunamaqondo aphantsi.
Nangona kunjalo, ngenxa yobushushu be-ambient, izinga apho ubomi be-LED buqala ukuhla kakhulu aliqhelekanga. Kuphela ukuba uyazi ukuba izixhobo zakho zokukhanyisa ziya kuboniswa kumaqondo obushushu aphezulu ixesha elide, ngaba kuyimfuneko ukufunda ukuba kunokuchaphazela njani ukhetho lwakho lokukhanyisa.
