Ukuhlolwa kokukhanya komgwaqo kwe-LED

Isibani somgwaqo se-LED sivame ukuba kude nathi, uma ukukhanya kwehluleka, sidinga ukuthutha yonke imishini namathuluzi adingekayo, futhi kudinga ubuchwepheshe ukuze sikulungise. Kuthatha isikhathi futhi izindleko zokulungisa zinzima. Ngakho-ke ukuhlola kuyisici esibalulekile. Ukuhlolwa kwesibani somgwaqo se-LED okuhlanganisa ukuhlolwa kokuvikela ukungena kwamanzi noma ukungena (IP), ukuhlolwa kokushisa, ukuhlolwa kokuvikela umthelela (IK), ukuhlolwa kokuguga, njalo njalo.

Ukuhlolwa kokuvikelwa kokungena (i-IP)

Kunquma ukuthi ukukhanya kuzovikela yini izingxenye ezisebenzayo emanzini, othulini, noma ekungeneni kwezinto eziqinile, kugcina umkhiqizo uphephile ngogesi futhi uhlala isikhathi eside. Ukuhlolwa kwe-IP kunikeza indinganiso yokuhlola ephindaphindwayo yokuqhathanisa ukuvikelwa kwendawo ebiyelwe. Isilinganiso se-IP simelela kanjani? Inombolo yokuqala kwisilinganiso se-IP imele izinga lokuvikelwa entweni eqinile kusukela esandleni kuya othulini, kanti inombolo yesibili kwisilinganiso se-IP imele izinga lokuvikelwa emanzini ahlanzekile kusukela ku-1mm yemvula kuya ekucwilisweni kwesikhashana kuze kufike ku-1m.

Thatha i-IP65 isibonelo, u-“6” usho ukuthi akukho ukungena kothuli, u-“5” usho ukuthi uvikelwe yizikhukhula zamanzi kunoma iyiphi i-engela. Ukuhlolwa kwe-IP65 kudinga ingcindezi engu-30kPa ebangeni elingama-3m, kanti umthamo wamanzi ungamalitha ayi-12.5 ngomzuzu, isikhathi sokuhlolwa umzuzu owodwa ngemitha yesikwele okungenani imizuzu emi-3. Kokukhanya okuningi kwangaphandle i-IP65 ilungile.

Ezinye izindawo ezinemvula zidinga i-IP66, okusho ukuthi “6” zivikelwe ezindizeni zamanzi ezinamandla kanye nolwandle olunzima. Ukuhlolwa kwe-IP66 kudinga ingcindezi engu-100kPa ebangeni elingamamitha angu-3, ​​kanti umthamo wamanzi ungamalitha ayi-100 ngomzuzu, isikhathi sokuhlolwa umzuzu owodwa ngemitha yesikwele okungenani imizuzu emi-3.

Ukuhlolwa kokuvikelwa komthelela (i-IK)

Izindinganiso zesilinganiso se-IK: I-IEC 62262 icacisa indlela okufanele kuhlolwe ngayo izivalo ukuze kuhlolwe izilinganiso ze-IK ezichazwa njengezinga lokuvikela izivalo ezinikezwayo emiphumeleni yangaphandle yemishini.

I-IEC 60598-1 (IEC 60529) ichaza indlela yokuhlola esetshenziselwa ukuhlukanisa nokukala izinga lokuvikelwa okunikezwa yi-enclosure ngokumelene nokungena kwezinto eziqinile ezinobukhulu obuhlukahlukene kusukela eminweni nasezandleni kuya othulini oluncane kanye nokuvikelwa ekungeneni kwamanzi kusukela ekuweni kwamaconsi kuya e-water jet enomfutho ophezulu.

I-IEC 60598-2-3 iyindinganiso Yomhlaba Wonke Yama-Luminaires Okukhanyisa Imigwaqo Nemigwaqo.

Izilinganiso ze-IK zichazwa njenge-IKXX, lapho u-“XX” eyinombolo esuka ku-00 kuya ku-10 ekhombisa amazinga okuvikelwa anikezwa yizindawo zokuvala zikagesi (kufaka phakathi izibani) emiphumeleni yangaphandle yemishini. Isikali sesilinganiso se-IK sikhomba ikhono lendawo yokuvala ukumelana namazinga amandla okushaya alinganiswa kuma-joules (J). I-IEC 62262 ichaza ukuthi indawo yokuvala kumele ifakwe kanjani ukuze kuhlolwe, izimo zomkhathi ezidingekayo, ubuningi kanye nokusatshalaliswa kwemithelela yokuhlolwa, kanye nesando sokushaya okumele sisetshenziswe ezingeni ngalinye lesilinganiso se-IK.
