Indlela yokusombulula ingxaki yamandla ekusetyenzisweni kwezibane zesitalato ze-LED

Indlela yokusombulula ingxaki yamandla ekusetyenzisweni kwezibane zesitalato ze-LED Ekusetyenzisweni kwezibane zesitalato ze-LED, kukho ingxaki yokuqwalasela iiprojekthi zokukhanyisa ezisekelwe kwisalathiso "samandla" sezibane. Nangona kunjalo, ukuba ukukhanya okupheleleyo kunye nesantya sokusetyenziswa kwezibane ze-LED kunye nezibane zesodium azibanjwanga ngokuchanekileyo, kulula ukubangela ukukhanya okukhanyayo okunganeleyo okanye umhlaba oqaqambileyo, njengoko kuboniswe kuMzobo 7. Oku kungenxa yokuba into esiyidingayo kukukhanya komhlaba. Ngokusekelwe kwiimpawu zezinto ezisemhlabeni, sinokufumana ukukhanya komhlaba, ukufumana ukukhanya okukhanyayo okufunekayo ngokoluhlu lokukhanyisa, kunye nokuguqula ukukhanya okukhanyayo kwezibane ngokwezinga lokusetyenziswa, ukugcinwa kwezinto, kunye nokucwangciswa kwezibane.

Emva kokufumana i-flux ekhanyayo, sinokubala amandla ngokuhambelana nokusebenza kwesibane. Ukuba umbane usetyenziswa ngokuthe ngqo, izinto ezininzi ezingaqinisekanga apha ngasentla ziya kuchaphazela ukufaneleka kokukhethwa kombane. 1. Uyilo lokukhanyisa alukho izikhombisi zokhuseleko kunye neziphumo, ezifana neLav, U0, UL, TI, SR, I80, njl.

Kuyafuneka ukuvavanya ukukhanya kwendlela, kodwa kukho izikhombisi zokhuseleko kunye nezibane zokukhanyisa. I-Lav isalathiso esichaphazela ukhuseleko lokuqhuba kunye nomthamo wezithuthi; I-U0 sisalathisi esichaphazela ukhuseleko lokuqhuba kunye nomthamo wendlela; I-UL isalathiso esichaphazela ukhuseleko lokuqhuba; I-TI sisalathisi esichaphazela ukhuseleko lokuqhuba; I-SR isalathiso esichaphazela induduzo yokuqhuba; I-I80 isalathiso esichaphazela induduzo yokuqhuba. Kufuneka kuqatshelwe ukuba ukukhanya kunxulumene nokukhanya okuguquguqukayo / umlinganiso wokubonakalisa umhlaba / i-engile yokujonga / ubungakanani bomphezulu wentelekelelo, njl njl.

Abaqhubi badla ngokujonga indlela ekumgama we-60-160 yeemitha kwaye babone ukukhanya okubonakaliswa kwiliso lomntu. Isalathiso sokukhanyisa asiyondawo ye-Brightness Index. Uguqulo lwe-luminance factor Q phakathi kokukhanya kunye nokukhanya alukho mgca ecaleni kwendlela yokuqhuba.

Okukhona ukhanyiso lufana ngokufanayo, kokukhona ukuqaqamba okufanayo akuyomfuneko. Ngoko ke, i-UE ayinakuthatha indawo ye-UL. Ukuqwalasela umphumo wokusabalalisa ukukhanya okusekelwe ekukhanyeni nasekukhanyeni, ngokusekelwe kwi-"uniformity ephezulu yokukhanya" ukukhanya kokukhanya, umlinganiselo we-UL ungaphantsi kwe-0.7, kwaye kuya kubakho ukunqumla kwe-zebra okucacileyo emhlabeni; ngokwe "uniformity ephezulu iyonke esekwe ekukhanyeni", umlinganiselo I-UL inkulu kuno-0.7.

Ukuthelekisa iziphumo zokukhanyisa izibane zesodium kunye ne-LED phantsi kwe-Ul efanayo, iimpawu zokusabalalisa ukukhanya kwezibane ze-sodium zigqiba ukuba kukho ukukhanya okulahlekileyo, kwaye umphumo ochanekileyo wokunciphisa ukukhanya kwee-LED kwenza ukukhanya okulahlekileyo kuncinci. Ukukhanya okulahlekileyo kunokuzalisa ukunqongophala kokuqaqamba kwiindawo ezimnyama, okanye wenze utshintsho olukhanyayo lube luncinci kakhulu. Xa kuthelekiswa nee-LED ezimhlophe, umbala wemithombo yokukhanya ye-sodium emva kokunciphisa ukukhanya kusondele kwi-asphalt pavement, umahluko wombala wezibane zesodium uphantsi, kwaye ukukwazi ukwahlula ukukhanya nobumnyama phantsi kweemeko zesibane zesodium kuphantsi.

Ngoko ke, phantsi kwe-Ul efanayo, izibane ze-sodium kunye nemithombo yokukhanya ye-LED kunokwenzeka ukuba ivelise ukuwela i-zebra. Ukongeza, kufunyenwe ukuba i-TI10% ilula kakhulu ukudlula umgangatho, kwaye i-TI20% glare ayicishwanga. Ukuba ayikhange iqwalaselwe, iimeko zokukhubazeka okanye ukwanda kwamanqanaba "okukhubazeka" kunokwenzeka.

I-I80 inkulu kune-200cd/m2, kwaye indawo yokukhanyisa yesibane incinci (njenge-cob LED isibane sesitalato), ekulula ukubangela ilitha elingathandekiyo.
