Ulwazi oluSisiseko lweModyuli yoMthombo wokuKhanya oDityanisiweyo we-LED

Kwishishini lokukhanyisa, ndihlala ndisiva oko kuthetha malunga neemodyuli zomthombo wokukhanya odibeneyo we-LED kwaye zeziphi iimodyuli zomthombo wokukhanya odibeneyo we-LED. Enyanisweni, imodyuli yomthombo wokukhanya odibeneyo we-LED kukulungiselela i-LED (i-light-emitting diode) ngokuhambelana nemithetho ethile kwaye uyifake, kunye nezinye iimveliso zonyango ezingenamanzi. Kukho umahluko omkhulu kwimiba yesakhiwo kunye ne-elektroniki kunye neemveliso ze-LED ngokubanzi. Okulula kukusebenzisa ibhodi yomgca kunye negobolondo exhotyiswe nge-LED ukuze ibe yimodyuli ye-LED. Ukuba wongeza ulawulo oluthile, unokongeza ulawulo oluthile ngomthombo wangoku oqhubekayo kunye nonyango olunxulumene nokutshatyalaliswa kobushushu. Ke ngoko, ukusetyenziswa kwemodyuli yomthombo wokukhanya odibeneyo we-LED kwiimveliso ze-LD nazo zibanzi kakhulu kwaye zithandwa kakhulu. Imodyuli ye-LED edibeneyo yomthombo wokukhanya isetyenziselwa ukubonisa umphumo wobusuku weefonti zentengiso kunye neelogo, kwaye ifezekise injongo yepropaganda. Ngokuqhelekileyo iboniswe ngendlela yokubhaliweyo okanye ukuchongwa, kunye nokuxhoma phezulu kwesakhiwo sorhwebo okanye udonga oluxhonywe. Kwimeko yemini, umphumo wokuchongwa unokwenziwa ngokuqhelekileyo. Kwangaxeshanye, i-LED isetyenziswa njengomthombo wokukhanya, ukuze ibonise esinye isiphumo ebusuku. Ukuba kwezinye iindawo ezinomoya wokonwabisa owomeleleyo, iya kuxhotyiswa ngokubanzi ngenkqubo yolawulo lokukhanya kwe-LED ukulawula ngokuguquguqukayo okubhaliweyo okanye ilogo ukwenza umoya usebenze ngakumbi. Ngoku sichaza ubukhulu becala iiparamitha zemodyuli yomthombo wokukhanya odibeneyo we-LED: 1. Umbala yiparameter esisiseko. Imibala eyahlukileyo isetyenziswa kwiimeko ezahlukeneyo. Ngokohlobo lombala, lunokwahlulwa lube ziindidi ezintathu: i-monochrome, inemibala, kunye ne-full-color-color-point control. I-Monochrome ngumbala omnye kwaye ayinakuguqulwa. Unokusebenza emva kokudibanisa unikezelo lwamandla. Imibala kukuba yonke imitya yeemodyuli inokuba ngumbala ofanayo kuphela, kwaye ayinakufezekisa imibala eyahlukileyo yemodyuli enye. Ngamagama alula, kuphela zonke iimodyuli ezinokuthi zifezekise umbala ofanayo kuphela ngexesha elinye. Ukutshintsha. Inqaku elinye lombala opheleleyo kukulawula umbala wemodyuli nganye. Xa inani leemodyuli lifikelela kwinqanaba elithile, umphumo wemifanekiso yokubonisa kunye nevidiyo inokufezekiswa. Qaphela ukuba amanqaku anemibala kunye nombala ogcweleyo kufuneka afakwe kwinkqubo yokulawula ukufezekisa umphumo. Okwesibini, i-voltage Le yiparameter ebaluleke kakhulu, kwaye ikwayi-parameter esisiseko kakhulu. Eyona nto ixhaphakileyo yimodyuli ye-12V low-voltage. Imisebenzi ebandakanyekayo kumbane iqwalaselwa ngokukodwa. Xa udibanisa ukunikezelwa kwamandla kunye nenkqubo yokulawula, kufuneka uhlolisise ukuchaneka kwexabiso lombane. Ngaphandle koko, ayinakuvuswa. Okwesithathu, ubushushu bokusebenza buthetha ubushushu bomsebenzi oqhelekileyo we-LED. Ngokuqhelekileyo, phakathi -20 60 , ukuba kukho kwiindawo apho izicelo, iimeko ezikhethekileyo ziqwalaselwa ngokukodwa. 4. Ilotho-hayi-lens ye-LED edityanisiweyo yemodyuli yomthombo wokukhanya wokukhanya ikakhulu yi-LED. Masithathe isigqibo sokuba umahluko kwi-LED uya kukhokelela kwi-angle yayo yokukhanya eyahlukileyo. Ke ngoko, abavelisi bahlala besebenzisa i-engile ye-engile ekhanyayo ye-LED njenge-engile yemodyuli yomthombo wokukhanya odibeneyo we-LED. 5. Ukukhanya kunye nokuqaqamba Le parameter yinto esisiseko. Yindawo ebaluleke kakhulu kwi-LED. Into esihlala siyithetha kwimodyuli yomthombo wokukhanya odibeneyo we-LED ihlala ibhekisa kumandla okukhanya kunye nokulibala. Kwimeko yamandla amancinci, i-luminous intensity (MCD) ngokuqhelekileyo kuthiwa. 6. Ukuba umgangatho wokungena kwamanzi usetyenziswe ngaphandle, kuya kubaluleka kakhulu ukuba imodyuli yomthombo wokukhanya odibeneyo we-LED isetyenziswe ngaphandle. Ngokuqhelekileyo, inqanaba lokungangeni kwamanzi kufuneka lifike kwi-IP65, ngaphandle koko liya kuchaphazela kwimeko yomoya kunye nemvula. 7. Ubude bodibaniso lwebar enye Le parameter isetyenziswa kakhulu xa kusenziwa iiprojekthi ezinkulu. Ibhekisa kwinani leemodyuli eziqhagamshelwe kwimodyuli yomthombo wokukhanya odibeneyo we-LED. Ngokuqhelekileyo oku kuhambelana nobukhulu bomgca woqhagamshelwano lwemodyuli yomthombo wokukhanya odibeneyo we-LED. 8. Ifomula yamandla ombane malunga nemodyuli yomthombo wokukhanya odibeneyo we-LED: Amandla emodyuli = amandla e-LED enye Inani le-LEDs 1.1.
