Imekobume yefektri yokutya

Izixhobo zokukhanyisa ezisetyenziselwa ukutya kunye nezityalo zokusela ziluhlobo olufanayo nakwiindawo eziqhelekileyo zoshishino, ngaphandle kokuba izixhobo ezithile kufuneka zenziwe phantsi kweemeko ezicocekileyo kwaye ngamanye amaxesha ezinobungozi.Uhlobo lwemveliso yokukhanyisa efunekayo kunye nemigangatho esebenzayo ixhomekeke kwindawo engqongileyo kwindawo ethile;amaziko okulungisa ukutya aqulathe iindidi ngeendidi zeemeko phantsi kophahla olunye.

Iifektri zinokubandakanya iindawo ezininzi ezifana nokulungiswa, ukugcinwa, ukuhanjiswa, ukugcinwa efrijini okanye okomileyo, amagumbi acocekileyo, iiofisi, iipaseji, iiholo, izindlu zangasese, njl. njl. Indawo nganye ineseti yayo yeemfuno zokukhanyisa.Umzekelo, ukukhanya ekulungiseni ukutyaiindawo ngokwesiqhelo kufuneka zimelane ne-oyile, umsi, uthuli, ubumdaka, umphunga, amanzi, ilindle, kunye nezinye izinto ezingcolisa umoya, kunye nokugungxulwa rhoqo kwezitshizi ezinoxinzelelo oluphezulu kunye nezinyibilikisi eziqatha zokucoca.

I-NSF iseke imigaqo esekelwe kwiimeko zengingqi kunye nobungakanani boqhagamshelwano oluthe ngqo nokutya.Umgangatho we-NSF wokutya kunye neemveliso zokukhanyisa iziselo, ezibizwa ngokuba yi-NSF/ANSI Standard 2 (okanye i-NSF 2), yahlula indawo yezityalo ibe ziindidi ezintathu zommandla: iindawo ezingezizo ukutya, iindawo zokuchaphaza, kunye neendawo zokutya.

Iinkcukacha zokukhanyisa ukwenzela ukulungiswa kokutya

Njengoninzi lwezicelo zokukhanyisa, i-IESNA (i-North American Lighting Engineering Association) ibeke amanqanaba okukhanyisa acetyiswayo kwimisebenzi eyahlukeneyo yokulungisa ukutya.Umzekelo, i-IESNA icebisa ukuba indawo yokuhlola ukutya inoluhlu lwesikhanyiso lwe-30 ukuya kwi-1000 fc, indawo yokuhlelwa kwemibala ye-150 fc, kunye nendawo yokugcina impahla, ukuthutha, ukupakisha, kunye negumbi langasese le-30 fc.

Nangona kunjalo, njengoko ukhuseleko lokutya lukwaxhomekeke ekukhanyeni okulungileyo, iSebe lezoLimo lase-US lifuna amanqanaba okukhanya afanelekileyo kwiCandelo 416.2(c) leNcwadi yoKhuseleko lokuTya kunye noHlolo lweNkonzo.Itheyibhile 2 idwelisa iimfuno zokukhanyisa ze-USDA kwiindawo ezikhethiweyo zokulungisa ukutya.

Ukuzala kakuhle kombala kubalulekile kuhlolo oluchanekileyo kunye nokuhlelwa kombala kokutya, ngakumbi inyama.ISebe lezoLimo lase-US lifuna i-CRI ye-70 kwiindawo zokulungisa ukutya ngokubanzi, kodwa i-CRI ye-85 kwiindawo zokuhlola ukutya.

Ukongeza, zombini i-FDA kunye ne-USDA ziphuhlise iinkcukacha zefotometric zokusasazwa kokukhanya okuthe nkqo.Ukukhanya komphezulu othe nkqo kufuneka kulinganise i-25% ukuya kwi-50% yokukhanya okuthe tyaba kwaye kungabikho thunzi apho kunokwenzeka ukuba kubekwe esichengeni iindawo ezibalulekileyo zezityalo.

Ukulungiswa kokutya Ukukhanyisa kwixesha elizayo:

• Ngokubhekiselele kwiimfuno ezininzi zococeko, ukhuseleko, okusingqongileyo kunye nokukhanya kwishishini lokutya kwizixhobo zokukhanyisa, abavelisi bezibane ze-LED kwishishini kufuneka bahlangabezane nezi zinto zilandelayo zoyilo eziphambili:
• Sebenzisa izinto ezingenayo ityhefu, ukumelana nomhlwa kunye ne-flame-retardant lightweight materials ezifana ne-polycarbonate plastic.
• Kuphephe ukusebenzisa iglasi ukuba kunokwenzeka
• Yila umphandle ogudileyo, ongenamanzi emzimbeni ongenazikhewu, imingxunya okanye iigrooves ezinokugcina iintsholongwane.
• Kuphephe ukupeyinta okanye ukugquma iindawo ezinokuxobuka
• Sebenzisa imathiriyeli yelensi eyomeleleyo ukumelana nokucocwa okuninzi, akukho tyheli, kunye nobubanzi kunye nokukhanya
• Isebenzisa ii-LED ezisebenzayo, ezihlala ixesha elide kunye ne-elektroniki ukuze zisebenze kakuhle kumaqondo obushushu aphezulu kunye nefriji
• Itywinwe nge-NSF-ithobela i-IP65 okanye i-IP66 izibane zokukhanyisa, zisengangeni manzi kwaye zikhusela ukuxinana kwangaphakathi phantsi koxinzelelo oluphezulu olugungxulwayo ukuya kuthi ga kwi-1500 psi (indawo yokutshiza)
• Kuba izityalo zokutya kunye neziselo zinokusebenzisa uninzi lweentlobo ezifanayo zokukhanyisa, iimveliso zokukhanya ze-LED ezimileyo zinokuba yenye indlela yokuqinisekisa i-NSF, kubandakanya:
• Izixhobo ezine-IP65 (IEC60598) okanye i-IP66 (IEC60529) yokulinganisa ukhuseleko

Iinzuzo zokukhanyisa ukutya kwe-LED

Kwishishini lokutya kunye nesiselo, ii-LED ezilungiselelwe ngokufanelekileyo zineenzuzo ezininzi ngaphezu kokukhanya kwendabuko, njengokungabikho kweglasi okanye ezinye izinto ezibuthathaka ezinokungcolisa ukutya, ukuphucula ukuphuma kokukhanya, kunye neemeko eziphantsi kobushushu kwindawo yokugcina ebandayo.Ukusebenza kakuhle, iindleko zokugcinwa okuphantsi, ubomi obude (iiyure ezingama-70,000), i-mercury engeyiyo inetyhefu, ukusebenza kakuhle okuphezulu, uhlengahlengiso olubanzi kunye nolawulo, ukusebenza kwangoko, kunye nobushushu obubanzi bokusebenza.

Ukuvela kokukhanya okusebenzayo okuqinileyo (SSL) kwenza kube lula ukusebenzisa i-smooth, lightweight, itywina, ikhanya, ukukhanya okusemgangathweni ophezulu kwizicelo ezininzi zoshishino lokutya.Ubomi obude be-LED kunye nokugcinwa okuphantsi kunokunceda ukuguqula imboni yokutya kunye nesiselo ibe yindawo ecocekileyo, eluhlaza.
