Zeziphi izinto eziphambili zezibane ze-LED?

Ngokwamkelwa ngokubanzi kweUkukhanya kwe-LED,, izibane zesiko kunye nezibane zeFluorescent zithathelwa indawo. Izibane ze-LED ayizizo kuphela amandla kwaye zinobomi beeyure ezingama-50000 kodwa zikwabonelela ngenzuzo yokuba i-mercury-ayinabuhlobo. Kodwa yintoni kanye kanye eyenza ukukhanya kwe-LED? Eli nqaku liza kukunceda uqonde itekhnoloji yange-infutha ye-LED ngokuhlalutya izinto eziphambili zezibane ze-LED.

Umsebenzi:I-chip ye-LED yeyona nto ikhuphayo yokukhupha ukukhanya kwe-LED. Xa kudlula umbane, i-elektrons kwi-semiconductor ye-semiconductor ye-semiconductor eqhubekayo kunye nokukhulula imibala, ukumisela umbala kunye nokuqaqamba kokukhanya.

Izixhobo:I-chips ngokuyintloko yenziwe kwizixhobo ze-semiconductor ezinje nge-geliyonium nitride (Gan) kunye ne-Gallium Arsenide (Gas). Iitshipsi ezisemgangathweni eziphezulu zinokufakwa izinto ezinje nge-aluminium naseIndim ukuphucula ukusebenza kunye nokuzinza.

Umsebenzi:Ulwakhiwo lokungenisa lubandakanya i-resin edibeneyo, ikhokelela kukhokelele, abonise, kunye nohlobo lokungenisa. Indima yayo kukukhusela i-chip kwi-oxidation kunye nemonakalo yomzimba ngelixa iqhuba ukukhanya ukukhanya. I-ista ecenation inceda ekusasazeni ukukhanya kwe-chip ngokulinganayo, kuphephe imiqadi egxile, ingqolowa.

Izixhobo:Izinto eziqhelekileyo ze-ecepatic resin zibandakanya i-epoxy ren okanye i-silicone yobushushu obuphezulu. Izikhokelo eziPhezulu zihlala zenziwa ngesilivere okanye zegolide. Abacimi banokwenziwa ngentsimbi okanye ngeplastiki, kunye neefom ze-encaplecation zibandakanya ngokusebenzisa-umngxunya (ukumelana nemozulu eyomeleleyo) kunye nendawo encinci (yesayizi encinci) phakathi kwezinye.

Umsebenzi:Inkqubo yokuyila i-SURD, iqulethe i-shrick etshisayo kunye nezakhiwo ezinobushushu, idlulisela ngokukhawuleza i-chip ukuthintela amaqondo obushushu amaninzi anokukhokelela ekunciphiseni ukonakaliswa kunye nokuncitshiswa kwe-wolpan.

Izixhobo:I-sharch swinks yenziwa ikakhulu ye-Aluminium Alloy, ngeemveliso zokuphela zisebenzisa ubhedu okanye idibanisa izinto ezisebenzayo. Ukunamathela okhethekileyo okuthe kratya kunokusetyenziselwa ukuphucula ukudluliselwa kwempumelelo.

Umsebenzi:Ubonelelo lwamandla okuqhuba lubandakanya i-PCB kunye nesekethe eqhubekayo ngoku, inoxanduva lokuguqula amandla kwi-DC yamandla e-DC kunye nokulawula ukuqina kwangoku ukuthintela i-chip.

Izixhobo:Iibhodi zesekethe zihlala zenziwa kwi-PCBS-Regial-Rexial-Rexial-PCBS, enganyangeki kunye nokuthambisa.

Umsebenzi:Amacandelo o-Optical aquka iilensi kunye neziBonelelo. I-lenses ilawula indlela yokukhanya kokukhanya ngokungxama okanye ngokucingisisa kwaye ikwazi ukulungelelanisa i-engile ye-beam. Ababona baqokelela ukukhanya kwiimilo zejometri njengemibala ye-paraboloids okanye i-ellipsoids kwaye ilahle ilahleko.

Izixhobo:Iilensi zenziwa ngokubanzi kwi-PMMA, i-PC, okanye iglasi, kwaye inokubandakanya iingubo ezinganyangekiyo ze-UV ukunciphisa ukugqobhoza. Abaceba bahlala benziwa nge-aluminium, yobhedu, okanye ngeplastiki.

Umsebenzi:Izindlu ngokuyintloko zikhusela izinto zangaphakathi ezivela kwiimpembelelo zangaphandle kwaye zikhusela umxholo ovela kumonakalo.

Izixhobo:Imigca yangaphandle ihlala isebenzisa ialuminium alloy yokunganyangeki. Izinto zangaphakathi zinokusebenzisa iplastiki ephosakeleyo yokusebenza kweendleko.

Lo mxholo ungasentla ubonelela ngenkcazo eneenkcukacha ngobume bezibane ze-LED. Lilonke, ukwenziwa kwesibane se-LED kuxhomekeke kwisenzo esilungelelanisiweyo sezinto zayo. I-chip ichaza ukusebenza kakuhle, inkqubo yokulahla inkunkuma ichaphazela i-Lifepan, kwaye umba wombane wokuqhuba uqinisekisa uzinzo. Eli nqaku linokukunceda uqonde umahluko phakathi kwezinto eziphambili kwaye ikuncede ekukhetheni iimveliso ezifanelekileyo.

Njengomthengisi okhokelayo okhokelayo,I-ToppoUngakunika izibane ezahlukeneyo ze-LEP ephezulu kwaye unike izisombululo ezenziwe ngokwezifiso zendawo yakho. Ukuba unayo nayiphi na imibuzo malunga nokukhanya kwale mihla, nceda uzive ukhululekile ukubaQhagamshelana nathi!
