Ishishini le-LED lishishini lesizwe elicwangcisiweyo elikhulayo, kwaye umthombo wokukhanya we-LED ngowona mthombo wokukhanya uthembisayo ngenkulungwane yama-21, kodwa ngenxa yokuba itekhnoloji ye-LED isekwinqanaba lophuhliso lokuvuthwa okuqhubekayo, ishishini lisenemibuzo emininzi malunga nomgangatho walo wokukhanya. iimpawu, eli phepha liza kudibanisa ithiyori kunye nokusebenza, ukuhlalutya imeko yangoku ye-LED kunye nolwalathiso lophuhliso lwexesha elizayo, ukukhuthaza uphuhliso olunempilo lweshishini le-LED.

Ubume bophuhliso loshishino lwe-LED kunye neendlela

a.Ngokwembono yomjikelezo wemveliso, ukukhanya kwe-LED kungene kwixesha elikhulile kakhulu.

Okwangoku, ukukhanya kwe-LED, nokuba kukukhanya kwangaphandle, okanye kwintsimi yokukhanyisa intengiso, ingena ngesantya esothusayo.

Kodwa ngeli nqanaba, indawo yokukhanya yasekhaya inokuchazwa njengengxowa edibeneyo, i-low-end, i-low-quality-quality-light-light-high-quality-light-high-quality-light-light-light-light-light-light-light-light-light-light-light-light-light-light-light-light-lightUkukhanyisa kwe-LED kusabambelele ekugcinweni kwamandla, ukukhuselwa kwendalo kunye nobomi obude bezibane.Ke ngoko, oku kukhokelela uninzi lwabavelisi bezibane ze-LED ukuba balandele ukusebenza kakuhle okukhanyayo kunye nokhuphiswano lweendleko eziphantsi, ngelixa betyeshela i-LED kwimpilo yabantu kunye nentuthuzelo kunye nemiba yokukhanya ekrelekrele yezicelo ezikumgangatho ophezulu.

b.Iphi indlela yexesha elizayo yoshishino lwe-LED?

Ukukhanya okukhanyayo kuya kuqhubeka nokuqhubela phambili kunye nokutsha kwezobuchwepheshe, okuyinkqubo engenakuphepheka yokuphuhliswa kwempahla, ngexesha lokukhanya okukhokelwa yi-LED, kuba umthombo wokukhanya uneentlobo zeplastiki, ukuphishekela umgangatho wokukhanya kuphucula.

Ukusuka kwimbono jikelele, imboni ye-LED okwangoku ikwinqanaba lophuhliso olucothayo, akusekho lutsha lwetekhnoloji olukhokelela kwishishini elibandakanyekayo kwimfazwe yamaxabiso, kwimfazwe yexabiso ngokuya kushushu mhlophe, ukunyanzela imarike kumgangatho, ikrelekrele kunye nezinye. imiyalelo.

Yintoni "ukukhanya" ngomgangatho?

Ngaphambili, izibane ze-LED ezikhanyayo, ezizinzileyo ezikhanyayo, njl., Isibane esilungileyo somgangatho.Kule mihla, ngombono wokukhanya okuluhlaza kunye neengcambu ezinzulu ezintliziyweni zabantu, umgangatho wenkcazo yomgangatho wokukhanya obalaseleyo utshintshile.

a.Inqanaba lokuphumelela ngobuninzi lidlulile, kwaye ixesha lokuphumelela ngomgangatho lifikile.

Xa sisebenzela abathengi baseMntla Melika, sifumanise ukuba iimfuno zabo zomgangatho wokukhanya kwe-LED ziya zisiba phezulu nangaphezulu.I-North American Lighting Commission i-IES icacise indlela entsha yokuvavanya i-TM-30 yekhono lokunika umbala wemithombo yokukhanya, iphakamisa izalathisi ezimbini zovavanyo olutsha lwe-Rf kunye ne-Rg, ebonisa ngokupheleleyo ukuba abalingane bamazwe ngamazwe baqhubela phambili uphando olukhanyayo lwe-LED.I-Blue King iya kwazisa ngokukhawuleza iindlela zokuvavanya ezinjalo e-China, ukuze abantu base-China banokonwabela ngokupheleleyo umthombo wokukhanya we-LED ophezulu.

I-TM-30 ithelekisa iisampulu zemibala engama-99, emele iintlobo ngeentlobo zemibala eqhelekileyo enokubonwa ebomini (ukusuka kwi-saturated ukuya kwi-unsaturated, ukusuka ekukhanyeni ukuya kumnyama)

Itshathi yombala we-TM-30

b.Kukuphela kokusukela ukukhanya kwe-LED komgangatho wokukhanya kunokuzisa intuthuzelo kubasebenzisi.

Umgangatho ophezulu weemveliso zokukhanyisa izibane ze-LED ngenxa yokugxila kwimpilo, umboniso ophezulu, iziphumo ezicacileyo zokukhanyisa, kwiimveliso ezahlukeneyo ukukhetha ubushushu bombala obuchanekileyo, kunye nezibane zibe nezidingo ezichasene ne-glare, zilawula iingozi zokuphuphuma kokukhanya okuluhlaza okwesibhakabhaka, kunye neenkqubo ezihlakaniphile. kulawulo lokukhanyisa, ukuhlangabezana nezityebi kunye neemfuno zolawulo olukrelekrele ezahlukeneyo.

c.LED ukubola ukukhanya

Ngokungafaniyo nezikhanyiso zemveli ezithanda ukusilela ngequbuliso ukuqhubeka nokusebenza, izibane ze-LED azidli ngokusilela ngequbuliso.Ngexesha lokusebenza kwe-LED, kuya kubakho ukubola kokukhanya.Uvavanyo lwe-LM-80 yindlela kunye nesalathisi sokuvavanya izinga lokugcinwa kwe-lumen yomthombo wokukhanya kwe-LED.

Ngengxelo ye-LM-80, unokufaka iprojekthi ubomi be-LED, kwi-IES LM-80-08 esemgangathweni ye-Lumen Maintenance Life;I-L70 (iiyure): ibonisa ukuba umthombo wokukhanya we-lumens ukubola ukuya kwi-70% ye-lumens yokuqala esetyenzisiweyo;I-L90 (iiyure): ibonisa ukuba umthombo wokukhanya we-lumens ubola ukuya kwi-90% ye-lumens yokuqala esetyenzisiweyo.

d.Isalathisi sonikezelo sombala ophezulu

Isalathiso sokubonisa umbala yindlela ebalulekileyo yokuvavanya unikezelo lombala wemithombo yokukhanya, kwaye ikwayiparameter ebalulekileyo yokulinganisa iimpawu zombala wemithombo yokukhanya eyenziweyo, echazwe nguRa/CRI.

I-Ra, i-R9 kunye ne-R15

Isalathiso sombala oqhelekileyo wesalathiso u-Ra ngumyinge we-R1 ukuya kwi-R8, kunye nesalathiso sombala we-CRI ngumyinge we-RI-R14.Asiqwalaselanga kuphela isalathiso sonikezelo lombala jikelele uRa, kodwa sikwanikela ingqalelo kwisalathiso esikhethekileyo sombala weR9 kumbala obomvu ohluthisiweyo, kunye nesalathiso sombala okhethekileyo R9-R12 kumbala obomvu, omthubi, oluhlaza noluhlaza okwesibhakabhaka, sikholelwa ukuba ezi izikhombisi zimela ngokwenene umgangatho wokukhanya kwe-LED, kunye nomthombo wokukhanya wokuthengisa ukukhanya, kuphela xa ezi zalathi zinexabiso eliphezulu zinokuqinisekisa ukunikezelwa kombala ophezulu we-LED.

Ngokuqhelekileyo, ixabiso eliphezulu, ngokusondeleyo kumbala wokukhanya kwelanga, ngokusondeleyo kumbala wayo wokuqala into ekhanyiswayo.Imithombo yokukhanyisa i-LED enombala ophezulu wokunikezelwa kwesalathisi idla ngokukhethwa kwishishini lokukhanyisa.Iimveliso ezibonelelwa yiBlue View zihlala zithatha i-CRI> 95 ngokwemfuno yomthengi, enokubuyisela ngokwenene umbala weempahla ekukhanyeni, ukuze kuphunyezwe ukukholisa kwamehlo kunye nokukhuthaza umnqweno wokuthenga abantu.

e.UkuKhanya okukhazimlayo

Kwi-1984, i-Illuminating Engineering Society yaseNyakatho Melika ichaze i-glare njengemvakalelo yokucasula, ukungahambi kakuhle okanye ukulahlekelwa kokusebenza okubonakalayo kwintsimi ebonakalayo ebangelwa ukukhanya okukhulu kunokuba iliso likwazi ukuziqhelanisa nalo.Ngokweziphumo, ilitha linokwahlulwa libe litha elingathandekiyo, ilitha eliguquguqukayo lokukhanya kunye ne-funereal glare.

I-LED linani elikhulu le-cylindrical okanye iphakheji ye-spherical, ngenxa yendima ye-convex lens, inombono oqinileyo, ukukhanya okukhanyayo kunye nemilo yephakheji eyahlukeneyo kunye nobukhulu obuxhomekeke kwicala le-angular: ibekwe kwicala eliqhelekileyo lokukhanya okukhulu kokukhanya, i-angle ye-intersection kunye nendiza ethe tye ye-90. xa uphambukela kwicala eliqhelekileyo le-engile eyahlukileyo ye-θ, ukukhanya kokukhanya kuyatshintsha.iimpawu zomthombo wokukhanya we-LED.Ukuze iimpawu zomthombo wokukhanya kwe-LED zibe nokukhanya okuphezulu kakhulu kunye neengxaki ze-glare zenzeka.Xa kuthelekiswa nezibane ze-incandescent, izibane ze-fluorescent, izibane zesodium ezinoxinzelelo oluphezulu kunye nezinye izibane zendabuko, ulwalathiso lwefiber optic lwezibane ze-LED zigxininise kakhulu kwaye zilungele ukuvelisa ukukhanya okungathandekiyo.

f. Iingozi zokukhanya eziBlue

Ngokuthandwa kwe-LED, ingozi yokukhanya okuluhlaza okwesibhakabhaka okanye ukuchitheka kokukhanya okuluhlaza kube yingxaki ekufuneka bonke abantu bajongane nayo kwaye bayisombulule, kwaye kwishishini le-luminaire akukho nto.

Umgangatho omtsha we-EU jikelele we-luminaire umisela ukuba ukuba i-luminaire ebandakanya i-LED, izibane ze-metal halide kunye nezibane ezikhethekileyo ze-tungsten halogen ezingenakukhululwa kuvavanyo lwengozi ye-retinal kufuneka zivavanywe ngokwe-IEC/EN62778:2012 “Ukhuseleko lokufotowa kwemithombo yokukhanya kunye nezibane izicelo zovavanyo lokulimala kokukhanya okuluhlaza okwesibhakabhaka”, kwaye akufanelekanga ukusebenzisa imithombo yokukhanya enamaqela obungozi okukhanya okuluhlaza okwesibhakabhaka angaphezu kwe-RG2.

Kwixesha elizayo, siya kubona iinkampani ezininzi, zingavelisi kuphela iimveliso zokukhanyisa i-LED, kwaye zingagxininisi kwiiparameters zomntu ngamnye wemveliso, kodwa zinokucinga malunga nendlela yokuphucula umgangatho wokukhanya okusekelwe kwikhonkco lexabiso ukusuka kwimveliso ukuya kulo lonke. ukufezekiswa kwemfuno.Kwinkqubo yokuphucula, ubuchule bokuyila ukukhanya, amandla okwenza imveliso, kunye nokusekwa kunye nokuphucula amandla okuphendula ngokukhawuleza, ngumceli mngeni ekufuneka iinkampani zijongene nazo.
