Ukugweba ukuba iUkukhanya kwe-LEDumthombo yinto esiyidingayo, siqhele ukusebenzisa i-sphere yokudibanisa ukuvavanya, kwaye emva koko sihlalutye idatha yovavanyo. Umda wokudibanisa ngokubanzi unokunika ezi parameters zintandathu zibalulekileyo zilandelayo: ukuguquguquka okukhanyayo, ukusebenza kakuhle okukhanyayo, amandla ombane, ulungelelwaniso lombala, ubushushu bombala, kunye nesalathiso sokunikezela ngombala (Ra). (Enyanisweni, zininzi ezinye iiparameters, ezinje ngobude obuphezulu, ubude belanga elilawulayo, umsinga omnyama, i-CRI, njl.njl.) Namhlanje, makhe sixoxe ngokubaluleka kwezi parameters ezintandathu kwimithombo yokukhanya kunye nefuthe lazo.

Ukukhanya okuguquguqukayo: Ukukhanya okukhanyayo kubhekisa kumandla emitha anokuviwa liliso lomntu, oko kukuthi, amandla emitha ewonke akhutshwa yi-LED, kwilumens (lm). Ukukhanya okuguquguqukayo ngumlinganiselo othe ngqo kunye nowona bungakanani bomzimba obubonakalayo ukugweba ukuqaqamba kwe-LED.

I-Voltage:I-voltage ngumahluko onokuthi ubekho phakathi kweepali ezilungileyo nezingalunganga zeIsibane se-LEDi-bead, engumlinganiselo othe ngqo, kwiivolthi (V). Inxulumene nombane we-chip osetyenziswa yi-LED.

Ukusebenza okuqaqambileyo:ukusebenza kakuhle okukhanyayo, oko kukuthi, umlinganiselo wawo wonke umsinga okhanyayo okhutshwa ngumthombo wokukhanya ukuya kumandla okufakwayo ewonke, sisixa esibaliweyo, kwi-lm/W. Kwi-LED, igalelo lamandla ombane lisetyenziselwa ukukhanyisa kunye nokufudumeza. Ukusebenza okuphezulu kokukhanya kubonisa ukuba kukho iindawo ezimbalwa ezisetyenziselwa ukufudumeza, nto leyo ebonisa ukuchithwa kakuhle kobushushu.

Kulula ukubona ubudlelwane phakathi kwaba bathathu bangasentla. Xa ikhoyo ngoku imiselwe, ukusebenza kakuhle okukhanyayo kwe-LED ngokwenene kumiselwa yi-flux ekhanyayo kunye ne-voltage.Ukukhanya okukhanyayo okuphezulukunye nombane ophantsi ukhokelela ekusebenzeni okukhanyayo okuphezulu. Ukuya kuthi ga ngoku kwi-chip enkulu eluhlaza okwesibhakabhaka yangoku igqunywe nge-fluorescence eluhlaza okwesibhakabhaka, kuba amandla ombane omnye wetshiphu eluhlaza ngokubanzi malunga ne-3V, elixabiso elizinzileyo, ukuphuculwa kokusebenza kokukhanya kuxhomekeke ekwandiseni ukuguquguquka okukhanyayo.

Ulungelelaniso lombala:ulungelelwaniso lombala, oko kukuthi, indawo yombala kwidayagram yechromaticity, ngubungakanani bomlinganiselo. Kwinkqubo eqhelekileyo esetyenziswa ngokuqhelekileyo ye-CIE1931 yombala, ulungelelwaniso lumelwe ngamaxabiso ka-x kunye no-y. Ixabiso lika-x linokuthathwa njengeqondo lokukhanya okubomvu kwi-spectrum, kwaye ixabiso lika-y lithathwa njengeqondo lokukhanya okuluhlaza.

Ubushushu bombala:ubungakanani obubonakalayo obulinganisa umbala wokukhanya. Xa imitha yomzimba omnyama ngokupheleleyo ifana ncam nemitha yomthombo wokukhanya kwindawo ebonakalayo, ubushushu bomzimba omnyama bubizwa ngokuba bubushushu bombala bomthombo wokukhanya. Ubushushu bombala bubungakanani bomlinganiselo, kodwa bunokubalwa ngokulungelelaniswa kombala ngexesha elinye.

Isalathiso sokubonisa umbala (Ra):isetyenziselwa ukuchaza ukubuyisela amandla omthombo wokukhanya kumbala wento. Kumiselwa ngokuthelekisa imbonakalo yombala wezinto phantsi komthombo wokukhanya oqhelekileyo. Isalathiso sombala wethu wonikezelo lwemibala eneneni ngumndilili wemilinganiselo yemibala ekhanyayo esibhozo ebalwa linqanaba elidityanisiweyo lokukhanya okungwevu obomvu, okungwevu tyheli okumnyama, okuluhlaza okwesibhakabhaka okugcweleyo, okuluhlaza okumthubi okuphakathi, okuluhlaza okwesibhakabhaka, okuluhlaza okwesibhakabhaka, okumfusa ngokukhanyayo, kunye nomfusa obomvu okhanyayo. . Kunokufunyaniswa ukuba ayibandakanyi ibomvu egcweleyo, eyaziwa njenge-R9. Ngenxa yokuba ezinye izibane zifuna ukukhanya okubomvu ngakumbi (njengokukhanya kwenyama), i-R9 isoloko isetyenziswa njengeparamitha ebalulekileyo yokuvavanya i-LED.

Ubushushu bombala bunokubalwa ngolungelelwaniso lombala. Nangona kunjalo, ukuba uqwalasela ngononophelo umzobo we-chromaticity, uya kufumanisa ukuba ubushushu bombala ofanayo bunokuhambelana nolungelelwaniso lwemibala emininzi, ngelixa idizayini yombala ihambelana kuphela nobushushu bombala omnye. Ngoko ke, kuchaneka ngakumbi ukusebenzisa ulungelelwaniso lombala ukuchaza umbala womthombo wokukhanya. Isalathiso sokubonisa ngokwaso asinanto yakwenza nolungelelwaniso lombala kunye nobushushu bombala, kodwa okukhona ubushushu bombala buphezulu, umbala wokukhanya ubanda ngakumbi, amacandelo abomvu angaphantsi kumthombo wokukhanya, kwaye kunzima ukufikelela kwisalathiso esiphakamileyo kakhulu. Kwimithombo yokukhanya efudumeleyo enobushushu obuphantsi bombala, kukho iinxalenye ezibomvu ezingaphezulu, ukugqunywa kwembonakalo ebanzi, kwaye ikufutshane nokukhanya kwendalo, ngoko ke isalathiso sombala sinokuba phezulu ngokwendalo. Kungenxa yoko le nto ii-LED ezingaphezulu kwe-95Ra kwimarike zinobushushu obuphantsi bombala.
