Hlola ukukhanya komgwaqo kwe-LED

Ukukhanya komgwaqo we-LED ngokuvamile kukude nathi, uma ukwehluleka ukukhanya, sidinga ukuthutha zonke izinto ezidingekayo namathuluzi, futhi kudinga ubuchwepheshe ukukulungisa. Kuthatha isikhathi futhi izindleko zokunakekela zinzima. Ngakho ukuhlola kuyisici esibalulekile. Ukuhlolwa kokukhanya komgwaqo kwe-LED okubandakanya ukuhlolwa kokuvikela amanzi noma ukungena ngaphakathi (IP), ukuhlolwa kwezinga lokushisa, ukuhlolwa kokuvikela umthelela (IK), ukuhlolwa kokuguga, nokunye.

Ukuhlolwa kwe-Ingress protection(IP).

Inquma ukuthi ukukhanya kuzovikela yini izingxenye zokusebenza emanzini, uthuli, noma ekungeneni kwento eqinile, igcine umkhiqizo uphephile ngogesi futhi uhlala isikhathi eside. Ukuhlolwa kwe-IP kunikeza indinganiso yokuhlola ephindaphindwayo ukuze kuqhathaniswe ukuvikelwa kwendawo ebiyelwe. Isilinganiso se-IP simelela kanjani? Idijithi yokuqala esilinganisweni se-IP imele izinga lokuvikela entweni eqinile ukusuka esandleni kuye othulini, kanti idijithi yesibili esilinganisweni se-IP imele izinga lokuvikelwa emanzini ahlanzekile ukusuka ku-1mm emvuleni kuya ekucwilisweni kwesikhashana kufika ku-1m. .

Thatha i-IP65 njengesibonelo, "6" isho ukungangeni kothuli, "5" isho ukuvikelwa kumajethi amanzi kunoma iyiphi i-engeli. Ukuhlolwa kwe-IP65 kudinga ingcindezi engu-30kPa ebangeni elingu-3m, nevolumu yamanzi engu-12.5 amalitha ngomzuzu, ubude besikhathi sokuhlola iminithi elingu-1 imitha yesikwele okungenani imizuzu emi-3. Ezibani eziningi zangaphandle IP65 ilungile.

Ezinye izifunda ezinemvula zidinga i-IP66, i-“6” isho ukuthi ivikelekile kumajethi amanzi anamandla nolwandle olunzima. Ukuhlolwa kwe-IP66 kudinga ingcindezi engu-100kPa ebangeni elingu-3m, nevolumu yamanzi amalitha ayi-100 ngomzuzu, ubude besikhathi sokuhlola iminithi elingu-1 imitha yesikwele okungenani imizuzu emi-3.

Ukuhlolwa kokuvikeleka komthelela(IK).

Amazinga wesilinganiso se-IK: I-IEC 62262 icacisa indlela izindawo ezivalekile okufanele zihlolwe ngayo izilinganiso ze-IK ezichazwa njengezinga lokuvikela izivalo ezihlinzekiwe ngokumelene nemithelela yangaphandle yokukhanda.

I-IEC 60598-1 (IEC 60529) icacisa indlela yokuhlola esetshenziselwa ukuhlukanisa kanye nokulinganisa izinga lokuvikela indawo evalekile ehlinzeka ngokugxambukela kwezinto eziqinile ezinosayizi ohlukahlukene ukusuka eminwe nasezandleni kuya othulini olucolekile kanye nokuvikelwa ekungeneni kwamanzi kusukela ekuweni okuwayo kuye endaweni. jet yamanzi anomfutho ophezulu.

I-IEC 60598-2-3 Izinga Lamazwe Ngamazwe Lezibani Zokukhanyisa Emgwaqeni Nokukhanya Emgwaqeni.

Izilinganiso ze-IK zichazwa ngokuthi I-IKXX, lapho u-“XX” kuyinombolo esuka ku-00 kuye ku-10 ebonisa amadigri okuvikela ahlinzekwa yizindawo ezivalekile zikagesi (okuhlanganisa nezibani) ngokumelene nemithelela yangaphandle yemishini. Isilinganiso sesilinganiso se-IK sikhomba ikhono lendawo ebiyelwe ukumelana namazinga wamandla omthelela alinganiswa ngama-joules (J). I-IEC 62262 icacisa ukuthi indawo ebiyelwe kufanele igxunyekwe kanjani ukuze ihlolwe, izimo zomoya ezidingekayo, ubuningi nokusatshalaliswa kwemithelela yokuhlola, kanye nesando somthelela esizosetshenziswa kuleveli ngayinye yesilinganiso se-IK.
