Mfundo yowunikira magetsi a LED

Opanga kuwala kwa LED amamvetsetsa zinthu zomwe zikugwirizana ndi LED; Pali mitundu yambiri yamagetsi a LED, ndipo zinthu zotsatirazi za opanga kuwala kwachitsanzo zimagwiritsidwa ntchito powunikira. Mofanana ndi nyali zachikhalidwe, nyali za LED zimapanganso kutentha. Kutentha kwa nyali za LED kumachokera ku kutayika kwa kutembenuka kwa photoelectric kwa ma LED ndi mphamvu ya galimoto ya LED. Mosiyana ndi mfundo yotulutsa kuwala kwa magetsi achikhalidwe, kuwala kwa LED ndi electroluminescence. Chifukwa cha vuto la kutembenuka mtima, mphamvu zambiri zotulutsa mphamvu zimasinthidwa kukhala mphamvu ya kutentha monga momwe zimakhalira ndi kugwedezeka kwa lattice komwe kumapangidwa ndi recombination yopanda ma radiation.

Njira yotumizira kutentha mu led si radiation koma conduction. Choncho, cholinga chofunika kwambiri pakupanga kutentha kwa magetsi okongoletsera a LED ndikuyendetsa bwino kutentha kwa chipangizo cha LED ndikuwongolera bwino kutentha kwa magetsi a LED mu nyali yokongoletsera ya LED.

Kukonzanso kosalekeza kwa zida zowunikira kwapereka nsanja yabwinoko yowunikira ntchito zomwe tikufuna kufotokoza. Sikuti amachepetsedwa kwambiri kuchokera ku mphamvu yogwiritsira ntchito mphamvu, koma amathanso kuphatikizidwa mu zamakono zamakono zamakono zamakono zamakono, zomwe zimapangitsa kuti zipangizo zamakono zikhalepo, zimawonjezera kusintha kwa magetsi okongoletsera a LED ndi kuyanjana ndi omvera, komanso kumapangitsanso chisangalalo cha ntchito.GLAMOR
