Ukugweba ukuba iUkukhanya kwe-LEDumthombo yinto esiyidingayo, siqhele ukusebenzisa i-sphere yokudibanisa yokuvavanya, kwaye emva koko sihlalutye ngokwedatha yovavanyo.Umda wokudibanisa ngokubanzi unokunika ezi parameters zintandathu zibalulekileyo: ukuguquguquka okukhanyayo, ukusebenza kakuhle okukhanyayo, amandla ombane, ulungelelwaniso lombala, ubushushu bombala kunye nesalathiso sokunikezelwa kombala (RA).(enyanisweni, kukho ezinye iiparamitha ezininzi, ezinje ngepeak wavelength, main wavelength, dark current, CRI, etc.) namhlanje siza kuxoxa ngokubaluleka kwezi parameters ezintandathu kumthombo wokukhanya kunye nefuthe labo elifanayo.

Ukukhanya okuguquguqukayo: ukukhanya okukhanyayo kubhekisa kumandla emitha anokuviwa ngamehlo abantu, oko kukuthi, amandla emitha ewonke akhutshwa yi-LED, iyunithi: ilumen (LM).I-Luminous flux ngumlinganiselo othe ngqo womlinganiselo kunye nowona mlinganiselo womzimba unengqondo ukugwebaukukhanya kwe-LED.

I-Voltage: i-voltage ngumahluko onokuthi ubekho phakathi kwee-electrode ezilungileyo kunye nezingalunganga zeIzibane zezibane ze-LED, oluyimilinganiselo ethe ngqo, iyunithi: iivolthi (V).Enxulumene nenqanaba lombane wetshiphu esetyenziswa yi-LED.

Ukusebenza okukhanyayo: ukusebenza kakuhle okukhanyayo, oko kukuthi, umlinganiselo wokukhanya okukhanyayo okukhutshwe ngumthombo wokukhanya kwigalelo lamandla ewonke, ubungakanani obalwayo, iyunithi: LM / W. Kwii-LEDs, amandla okufakwayo asetyenziselwa ukukhutshwa kokukhanya kunye nobushushu. isizukulwana.Ukuba ukukhanya okukhanyayo kuphezulu, kuthetha ukuba kukho iindawo ezimbalwa ezisetyenziselwa ukuveliswa kobushushu, nto leyo ebonisa ukuchithwa kakuhle kobushushu.

Akunzima ukubona ubudlelwane phakathi kwezi ntsingiselo zintathu zingasentla.Xa ukusetyenziswa kwangoku kumiselwe, ukukhanya okukhanyayo kwe-LED ngokwenene kugqitywa yi-flux ekhanyayo kunye ne-voltage.Ukuba i-flux ekhanyayo iphezulu kwaye i-voltage iphantsi, ukukhanya kokukhanya kuphezulu.Ngokumalunga nechipphu enkulu eblue yangoku egqunywe ngefluorescence eluhlaza okwesibhakabhaka, kuba amandla ombane omnye wetshiphu eluhlaza ngokubanzi ijikeleze i-3V, elixabiso elizinzileyo, ukuphuculwa kokusebenza kokukhanya kuxhomekeke kuphuculo lokukhanya okukhanyayo.

Ulungelelwaniso lombala: ulungelelwaniso lombala, oko kukuthi, indawo yombala kwidayagram yechromaticity, eyisixa somlinganiselo.Kwinkqubo eqhelekileyo ye-CIE1931 ye-colorimetric esetyenziswa ngokuqhelekileyo, ulungelelwaniso lumelwe ngamaxabiso e-X kunye no-Y.Ixabiso lika-x linokuthathwa njengeqondo lokukhanya okubomvu kwi-spectrum, kwaye ixabiso lika-y lithathwa njengeqondo lokukhanya okuluhlaza.

Ubushushu bombala: Ubungakanani bomzimba obulinganisa umbala wokukhanya.Xa imitha ye-blackbody epheleleyo kunye nemitha yomthombo wokukhanya kwindawo ebonakalayo ifana, ubushushu bomntu omnyama bubizwa ngokuba bubushushu bombala womthombo wokukhanya.Ubushushu bombala bubungakanani obulinganisiweyo, kodwa bunokubalwa ngolungelelwaniso lombala.

Umbala wokunikezelwa kwesalathiso (RA): sisetyenziselwa ukuchaza amandla omthombo wokukhanya ukubuyisela umbala wento.Kuchongwa ngokuthelekisa ukubonakala kombala wento phantsi komthombo wokukhanya oqhelekileyo.Isalathiso sombala wethu wonikezelo ngenene lixabiso elingumndilili elibalwe ludidi oludityanisiweyo lwemilinganiselo yemibala esibhozo engwevu ebomvu, emnyama engwevu tyheli, eluhlaza okwesibhakabhaka egcweleyo, emthubi ophakathi, eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka kunye nobomvu okhanyayo. mfusa.Kunokufunyanwa ukuba ayibandakanyi ubomvu obugcweleyo, oko kukuthi, i-R9.Ekubeni ukukhanya okunye kufuna ukukhanya okubomvu okungaphezulu (njengokukhanya kwenyama), i-R9 isoloko isetyenziswa njengeparameter ebalulekileyo yokuvavanya ii-LED.

Ubushushu bombala bunokubalwa ngolungelelwaniso lombala, kodwa xa uqwalasela ngononophelo itshathi yechromaticity, uya kufumanisa ukuba ubushushu obufanayo bombala bunokuhambelana nezibini ezininzi zolungelelwaniso lwemibala, ngelixa iperi yemibala elungelelanisiweyo ihambelana kuphela nobushushu bombala omnye.Ngoko ke, kuchaneka ngakumbi ukusebenzisa ulungelelwaniso lombala ukuchaza umbala womthombo wokukhanya.Isalathisi somboniso ngokwaso asinanto yakwenza nolungelelwaniso lombala kunye nobushushu bombala.Nangona kunjalo, xa ubushushu bombala buphezulu kwaye umbala okhanyayo upholile, icandelo elibomvu kumthombo wokukhanya lincinci, kwaye isalathisi sokubonisa kunzima ukuba siphezulu kakhulu.Ngomthombo wokukhanya ofudumeleyo kunye nobushushu bombala ophantsi, icandelo elibomvu lingaphezulu, ukugubungela i-spectrum kubanzi, kwaye i-spectrum isondele kukukhanya kwendalo, isalathisi sombala sinokuphakama ngokwendalo.Esi sisizathu sokuba ii-LED ezingaphezulu kwe-95ra kwimarike zinobushushu obuphantsi bombala.
