Ukufaneleka phakathi kwe-LED yokuBonisa uBubushushu kunye neGolide okanye iiNcingo zeChip ze-LED

Ngaba uvile ngentetho yakudala ethi "ufumana kuphela oko uhlawulayo".

Kuthekani ngokuthi “awunakwenza isipaji sesilika ngendlebe yehagu”?

Le ayisiyoblogi malunga nawe ole IsiNgesi okanye amabinzana asekuhlaleni, kodwa inye into onokuthi 'uyise ebhankini' (uxolo) kukuba uhlala ufumana le nto uyihlawulelayo - kwaye iziboniso ze-LED azihlukanga.

I-SMD (i-Surface Mounted Design) iqulethe i-3 ye-RGB ye-LED (Ebomvu, eBlue, eluhlaza) ngaphakathi kwesikwere esimhlophe se-LED osibonayo.

(Ngaba uyazi ukuba xa ubeka zonke i-RGB ezintathu ngaxeshanye, unokubona obomvu, oluhlaza okwesibhakabhaka kunye nohlaza xa usondele, kodwa nje ukuba ubuyele umva loo LED ibe ngumbala omnye omhlophe?)

Ukukunika isishwankathelo sayo yonke i-LED, jonga kwi-heatsink slug (isiseko) kunye ne "flip chip" ngaphakathi kwelensi ye-epoxy, kwaye iqhagamshelwe ngegolide (okanye yobhedu) ngocingo olungezantsi.

I-Dip LED Display yi-LED nganye oyibonayo idityaniswe ngokwahlukeneyo ngaphandle njengemibala eyahlukileyo - ke uya kubona enye (okanye emibini) ebomvu, enye eluhlaza okwesibhakabhaka, enye eluhlaza, edityaniswe kunye kwaye zonke ezi-3 zisebenza kunye ngaphakathi (zithi) 10mm isithuba, ukuvelisa umbala ofunekayo kuloo ndawo yomfanekiso.

Isikrini se-LED yocingo lweGolide VS iSikhusi se-LED yocingo lobhedu:

• Impahla Ephathekayo

Olona phawu lubalulekileyo noluluncedo kakhulu aigolide wire LED screenkukuba ipropathi yayo ebonakalayo izinzile kakhulu.

Ngenxa yoko, isiboniso socingo lwegolide sinokukunika ngokulula ukusebenza komgangatho, nakwiindawo ezinzima.

Apho kwelinye icala, ukudityaniswa kocingo lwekopha kwisibonisi sesikrini se-LED kunokuba lula ngakumbi ngaphandle kwe-oxidized ngaphandle kweengcingo zegolide ngakumbi kwindawo yangaphandle yokukhanya okuphezulu, umahluko kubushushu phakathi kwemini nobusuku kunye nokukhutshwa kobushushu.

Oku kubenza bangahlali ixesha elide kwaye bazinze kusetyenziso lwangaphandle, xa kuthelekiswa nezikrini zocingo lwegolide.

• Ubungakanani beChip ye-LED

Ngocingo lwegolide lugqume izibane kwi-SMD okanye DIP isibonisi LEDube nesayizi enkulu ye-LED yetshiphu xa kuthelekiswa naleyo yocingo lobhedu olugqunyiweyo lwesibane.

Ngoku le chip inkulu ivumela isibane se-LED ukuba sibonise ukukhanya okuphezulu ngelixa sisebenzisa amandla amancinci.

Ngaphandle koko, le chip yegolide enkulu ye-LED ikwabonelela ngomboniso ngokutya okungcono kokutya.

Ngenxa yoko, ngcono ukuchithwa kokufudumeza kwesibane se-LED kuqinisekisa ukuba umboniso we-LED usebenza njengesixhobo sombane esihlala ixesha elide kunye nexesha elide.

• Izibiyeli zezibane

Ukusetyenziswa okwahlukileyo kwezibiyeli zesibane kuzo zombiniigolide wire LED screenkwaye iucingo lobhedu LED screennazo zahlukile.

Ekubeni ucingo lwegolide lufakwe kwisiboniso se-LED sisebenzisa isibiyeli sesibane sobhedu kwisiboniso sesikrini, kunceda ukubonelela ngokubonisa ukutshatyalaliswa kokufudumeza okungcono.

Nangona kunjalo, iingcingo zobhedu zifakwe kwiibrakethi zentsimbi, ezenza ukuba zingasebenzi kakuhle ngokubhekiselele ekutshiseni ukufudumala.

Ukongeza, izibiyeli zobhedu zikwasebenza ngokuzinzileyo, njengoko aziyi kujongana nemiba yokurusa ngokulula.

• Ixabiso lokubonisa i-LED

Okokugqibela, kwaye okona kubaluleke kakhulu, aigolide wire LED screenIbiza kakhulu ngokwemigaqo yocingo lobhedu lwe-LED, kwaye i-iron wire led ibonisa eyona ingabizi kakhulu kodwa uyawazi umgangatho.

Isixa semali onokuthi utyale kwiscreen se-LED ngowona mba uphambili omisela ukuba zeziphi iimpawu kunye nokusebenza ngokufanelekileyo kwe-LED oya kuyifumana, ke ukuba uceba ukufumana into emangalisayo, kufuneka ubeke isixa esimangalisayo. .

I-YONWAYTECH njengomvelisi womboniso we-LED oqeqeshiweyo, sicebisa umxhasi wethu ukuba asebenzise isikrini sentambo yobhedu kumboniso wangaphakathi okanye wangaphandle wokurenta, sinokusebenzisa isikhokelo sobhedu esikhokelela kumboniso okhokelwayo.Ukuthelekisa kunye ne-leadframe yentsimbi eqhelekileyo iholele, ubhedu lunokufikelela kwintsebenzo engcono njengokutshatyalaliswa kobushushu.

Iingcingo zegolide ezikhokelela iitshiphusi ziqwalaselwe ngesakhelo se-LED sobhedu esicetyiswayo kusetyenziso lwentengiso yangaphandle ingakumbi ukukhanya okuphezulu ≥10000nits/sqm.

Ukuqukumbela kuzo zonke ezingentla, igolide inika ukuthembeka okukhulu (kunye nokusebenza okuhlala ixesha elide) kuba ayifaki oxidize ngokulula njengobhedu, kwaye iqhuba ngcono.

Esona sizathu sokusetyenziswa kobhedu kungenxa yexabiso eliphantsi kakhulu kunocingo lwegolide, kodwa ukusebenza akukubi kusetyenziso lwangaphakathi.

Kodwa ngelishwa, umntu usabambelele kumboniso okhokelwayo wexabiso eliphantsi, mhlawumbi uya kujongana nomboniso okhokelwa yintsimbi.

Ukuba ufuna ukuthenga isiboniso se-LED esingabizi kakhulu kwaye singabizi, uya kufumana ucingo lwentsimbi luya kuba ngaphakathi kuluhlu lwamaxabiso akho, kodwa ungothuki xa uqala ukuba nemiba yokusebenza ngexesha elifutshane njengoko uya kumangaliswa kukwazi “wena. fumana kuphela oko ukuhlawulelayo”.

Ukuba ungathanda ukufunda ngakumbi malunga neshishini lakho lokubonisa elikhokelayo, nceda ungalibazisi ukuqhagamshelana nathi.
