I. UHlolo olubonakalayo kwizibane ze-LED
Iimfuno zembonakalo: Ngokuhlolwa okubonakalayo kwiqokobhe kunye nokugubungela malunga ne-0.5m kude nesibane, akukho kuguqulwa, ukukrwela, ukukrazula, ipeyinti esusiweyo kunye nokungcola;izikhonkwane zoqhagamshelwano azikhubeki;ityhubhu yefluorescent ayikhululekanga kwaye akukho sandi singaqhelekanga.
Iimfuno zomda: Imilinganiselo yolwandlalo iyakuhlangabezana neemfuno zokuzoba.
Miimfuno ze-aterial: Izinto kunye nesakhiwo sesibane siya kuhlangabezana neemfuno ekuzobeni.
Iimfuno zeNdibano: Izikrufu zokuqina kumphezulu wesibane ziya kuqiniswa ngaphandle kokushiya;akukho cala libukhali, akukho lubukhali;zonke iindibano ziya kuqina kwaye zingakhululeki.
II.Iimfuno zokuSebenza kwezibane ze-LED
Izibane ze-LED zifuna inkqubo elungileyo yokupholisa.Ukuqinisekisa umsebenzi oqhelekileyo wezibane ze-LED, ubushushu bebhodi yesekethe esekwe kwi-aluminium abuyi kuba ngaphezulu kwe-65 ℃.
Izibane ze-LED ziya kuba nazoumsebenzilokhuseleko lobushushu obugqithisileyo.
Izibane ze-LED zilawula ukujikeleza okungaqhelekanga kwaye kufuneka zibe nesixhobo sokuxubha kunye ne-3C, i-UL okanye isiqinisekiso se-VDE sokukhusela i-overcurrent kwimeko yesekethe engaqhelekanga.
Izibane ze-LED ziya kukwazi ukumelana nokungaqhelekanga.Ngamanye amagama, uluhlu ngalunye lwe-LED luqhutywa ngumbane ozimeleyo okhoyo ngoku.Kwimeko yesekethe emfutshane ebangelwa kukuqhekeka kwe-LED, umbane okhoyo ngoku oqhubekayo uya kuqinisekisa umsebenzi okhuselekileyo wesekethe ngokuzinzileyo.
Izibane ze-LED ziya kuba nobumanzi kwaye zikwazi ukususa ukufuma kunye nokuphefumla.Ibhodi yesekethe yangaphakathi yezibane ze-LED kufuneka zibe nobungqina bokufuma kunye ne-ventilative kunye nesixhobo sokuphefumla.Ukuba izibane ze-LED zichatshazelwa kukufuma, ziya kuhlala zisebenza ngokuzinzileyo kwaye zisuse ukufuma ngokuxhomekeke kubushushu ezibuvelisayo ngexesha lomsebenzi.
Umlinganiselo phakathi kokuhla ukuhla kunye nokusetyenziswa kwamandla kwezibane ze-LEDis ≥56LM／W.
III.Uvavanyo lweSiza kwizibane ze-LED
1. Ukutshintsha uvavanyo lobomi
Kwi-voltage elinganisiweyo kunye ne-frequency elinganisiweyo, izibane ze-LED zisebenza imizuzwana engama-60 kwaye emva koko ziyeke ukusebenza imizuzwana engama-60, ezijikeleza amaxesha angama-5000, izibane zefluorescent.unakoisasebenza ngokuqhelekileyo.
2. Uvavanyo lokuqina
Kwimekobume ngaphandle kokuhanjiswa komoya kwiqondo lobushushu eliyi-60℃±3℃ kunye nobuninzi bokufuma obumalunga nama-60%, izibane ze-LED zisebenza iiyure ezingama-360 ngokuqhubekayo kumbane olinganisiweyo kunye nesantya esilinganiselweyo.Ukukhanya kwabo okukhanyayo akusayi kuba ngaphantsi kwe-85% yokuqala yokukhanya okukhanyayo emva koko.
3. ukhuseleko overvoltage
Ekukhuselweni kwe-overvoltage ekupheleni kwegalelo, ukuba i-voltage ye-input iyi-1.2 yexabiso elilinganisiweyo, isixhobo sokukhusela i-overvoltage siya kwenziwa sisebenze;emva kokuba amandla ombane abuyele ukuba aqheleke, izibane ze-LED ziya kuphinda ziphinde zibuyele.
4. HUbushushu obuphantsi kunye novavanyo lobushushu obuphantsi
Ubushushu bovavanyo yi -25℃ kunye +40℃.Ubude bexesha lovavanyo yi-96±2 iiyure.
-Huvavanyo lobushushu
Iisampuli zovavanyo ezingapakishwanga ezihlawuliswe ngombane kwiqondo lobushushu begumbi zifakwa kwigumbi lovavanyo.Lungisa iqondo lobushushu kwigumbi libe (40±3)℃.Iisampulu kumbane olinganisiweyo kunye nokusebenza rhoqo iiyure ezingama-96 ngokuqhubekayo kwiqondo lobushushu (ixesha liya kuqala ukusuka kwixesha lozinzo lobushushu).Emva koko unqumle ukunikezelwa kwamandla kwegumbi, khupha iisampuli kwaye uzigcine kwindawo yokushisa kweeyure ezingama-2.
-Uvavanyo lobushushu obuphantsi
Iisampuli zovavanyo ezingapakishwanga ezihlawuliswe ngombane kwiqondo lobushushu begumbi zifakwa kwigumbi lovavanyo.Lungisa iqondo lobushushu kwigumbi libe (-25±3)℃.Iisampulu kumbane olinganisiweyo kunye nokusebenza rhoqo iiyure ezingama-96 ngokuqhubekayo kwiqondo lobushushu (ixesha liya kuqala ukusuka kwixesha lozinzo lobushushu).Emva koko unqumle ukunikezelwa kwamandla kwegumbi, khupha iisampuli kwaye uzigcine kwindawo yokushisa kweeyure ezingama-2.
Test isiphumo isigwebo
Ukubonakala kunye nesakhiwo sezibane ze-LED aziyi kuba notshintsho olucacileyo ekuhloleni okubonakalayo.Ukukhanya okuqhelekileyo kuvavanyo lokugqibela akuyi kuba ngaphantsi kwe-95% yokukhanya okuphakathi kuvavanyo lokuqala;ukutenxa phakathi kwendawo yoxande lokukhanyisa emva kovavanyo kunye nommandla wokuqala woxande lokukhanya awuyi kuba mkhulu kune-10%;ukuphambuka kobude okanye ububanzi boxande abuyi kuba mkhulu kune-5%;Ukutenxa kwe-engile phakathi kobude kunye nobubanzi boxande akuyi kuba mkhulu kuno-5 °.
5. Fuvavanyo lokuwa ree
Iisampulu zovavanyo ezingahlawuliswanga kunye nephakheji epheleleyo kubude be-2m ziwa ngokukhululekileyo ngamaxesha angama-8.Ziwela amaxesha ama-2 ngokwahlukeneyo kwiindlela ezi-4 ezahlukeneyo.
Iisampuli emva kovavanyo aziyi konakaliswa kwaye izibophelelo aziyi kukhululeka okanye ziwe;ukongeza, imisebenzi yeesampulu iya kuba yesiqhelo.
6. Ukudibanisa uvavanyo lwesphere
Ukukhanya okukhanyayoibhekisele kwiamandla emitha amehlo omntu ayakwazi ukuva.Iyalinganato imveliso yamandla emitha kwibhanti yamaza ngexesha leyunithi kunye nokubonakala okuzalanayo kwibhendi yamaza.Uphawu Φ (okanye Φr) lubonisa ukukhanya okukhanyayo;iyunithi yokukhanya okukhanyayo yi-lm (lumen).
a.Ukukhanya okuguquguqukayo bubunzulu obukhanyayo obufikelela, bushiye okanye budlule umphezulu ogobileyo ngexesha leyunithi nganye.
b.Ukukhanya okuguquguqukayo ngumlinganiselo wokukhanya okhutshwa kwibhalbhu.
-Isalathiso soMbala wonikezelo (Ra)
ra isalathiso sombala wonikezelo.Kuvavanyo lobungakanani kunikezelo lombala wemvelaphi yokukhanya, ingqikelelo yesalathiso sombala iyaziswa.Chaza isalathisi sombala womthombo wokukhanya osemgangathweni ukuba ube yi-100;Isalathiso sokubonisa umbala seminye imithombo yokukhanya singaphantsi kwe-100. Izinto zibonisa umbala wazo wokwenyani phantsi kokukhanya kwelanga kunye nokukhanya kwe-incandescent.Ngaphantsi kwesibane sokukhutshwa kwegesi kunye ne-spectrum engapheliyo, umbala uya kuphazamisa kwiidigri ezahlukeneyo.Iqondo lokuboniswa kombala wokwenyani womthombo wokukhanya kubizwa ngokuba kukuboniswa kombala komthombo wokukhanya.Umyinge wesalathiso sombala wonikezelo lwemibala eli-15 eqhelekileyo ibonakaliswa nguRe.
Ubushushu bombala: iyunithi yokulinganisa equlethe umbala kwimitha yokukhanya.Ngokwethiyori, iqondo lobushushu lomzimba omnyama lithetha umbala womzimba omnyama ngokupheleleyo oboniswe ukusuka kwidigri ye-zero ngokupheleleyo (-273℃) ukuya kumaqondo obushushu aphezulu emva kokuba ishushubeziwe.Emva kokuba umzimba omnyama ushushu, umbala wawo utshintsha ukusuka kumnyama ukuya kubomvu, ophuzi,ngokomhlophe kwayeekugqibeleniluhlaza.Emva kokuba umzimba omnyama ufudunyezwe ukuba ube kubushushu obuthile, icandelo le-spectral eliqulethwe ekukhanyeni okukhutshwa ngumzimba omnyama libizwa ngokuba yiqondo lokushisa lombala kwiqondo lokushisa.Iyunithi yokulinganisa ngu-“K” (Kelvin).
Ukuba icandelo le-spectral eliqulethwe kukukhanya okukhutshwa ngumthombo wokukhanya liyafana naleyo yokukhanya okukhutshwa ngumzimba omnyama kubushushu obuthile, ibizwa ngokuba yi-*K yobushushu bombala.Umzekelo, umbala wokukhanya webhalbhu ye-100W uyafana nowomzimba omnyama ngokupheleleyo kubushushu obungama-2527℃.Ubushushu bombala wesibane esikhutshwa yibhalbhu iya kuba:(2527+273)K=2800K.
IV.Izibane ze-LED zokuPakisha uvavanyo
1.Impahla yokupakisha esetyenzisiweyo iya kuba ichanekile.Ipakethi esetyenzisiweyo kufuneka iphumelele uvavanyo lwasimahla lokuwa.
2. Ushicilelo olukwipakethi yangaphandle luya kuba luchanekile, kubandakanywa imaski ephambili, uphawu lwecala, inombolo ye-odolo, ubunzima bomnatha, ubunzima obupheleleyo, inombolo yemodeli, imathiriyeli, inombolo yebhokisi, umzobo wemodeli, indawo yemvelaphi, igama lenkampani, idilesi, isimboli yokuqina, Isimboli ye-UP, isimboli yokukhusela ukufuma njl.njl. Ifonti eprintiweyo kunye nombala ziya kuchaneka;abalinganiswa kunye nemifanekiso iya kucaca ngaphandle komfanekiso wesiporho.Umbala webhetshi epheleleyo uya kuhambelana nombala wephalethi;Ukuphambuka okucacileyo kwechromatic kwibhetshi epheleleyo kuya kuthintelwa.
3.Yonke imilinganiselo iya kuba ichanekile:impazamo ±1/4 intshi;Ukucofa umgca kuya kulunga kwaye kuvalwe ngokupheleleyo.Qinisekisa izixhobo ezichanekileyo.
Ikhowudi ye-4.Bar iya kucaca kwaye ihlangabezane neemfuno zokuskena.
