Uvavanyo lokukhanya kwesitalato se-LED

Isibane sesitalato se-LED sihlala sikude nathi, ukuba sikhanyiswa sisibane, kufuneka sithuthe zonke izixhobo nezixhobo ezifunekayo, kwaye kufuneka ubuchwepheshe ukuze silungiswe. Kuthatha ixesha kwaye iindleko zokulungisa zinzima. Ngoko ke uvavanyo lubaluleke kakhulu. Uvavanyo lwesibane sesitalato se-LED luquka uvavanyo lokukhusela ukungena kwamanzi okanye ukungena (IP), uvavanyo lobushushu, uvavanyo lokukhusela impembelelo (IK), uvavanyo lokwaluphala, njalo njalo.

Uvavanyo lokukhusela ukungena (IP)

Imisela ukuba isibane siya kukhusela iindawo ezisebenzayo emanzini, eluthulini, okanye ekungeneni kwezinto eziqinileyo, sigcine imveliso ikhuselekile ngombane kwaye ihlala ixesha elide. Uvavanyo lwe-IP lubonelela ngomgangatho wovavanyo oluphindaphindwayo ukuthelekisa ukhuseleko oluvalekileyo. Lumela njani ulinganiselo lwe-IP? Idijithi yokuqala kumlinganiselo we-IP imela inqanaba lokhuseleko kwinto eqinileyo ukusuka esandleni ukuya eluthulini, kwaye idijithi yesibini kumlinganiselo we-IP imela inqanaba lokhuseleko kumanzi acocekileyo ukusuka kwi-1mm yemvula ukuya ekuntywilisweni okwethutyana ukuya kuthi ga kwi-1m.

Umzekelo, i-IP65 ithetha ukuba akukho luthuli lungena, i-“5” ithetha ukuba ikhuselekile kwiijethi zamanzi kuyo nayiphi na i-engile. Uvavanyo lwe-IP65 lufuna uxinzelelo lwe-30kPa kumgama we-3m, kunye nomthamo wamanzi weelitha ezili-12.5 ngomzuzu, ixesha lovavanyo ngumzuzu omnye ngemitha yesikwere ubuncinane imizuzu emi-3. Kwizibane ezininzi zangaphandle i-IP65 ilungile.

Ezinye iindawo ezinemvula zifuna i-IP66, i-“6” ithetha ukuba ikhuselekile kwiijethi zamanzi ezinamandla kunye nolwandle olunzima. Uvavanyo lwe-IP66 lufuna uxinzelelo lwe-100kPa kumgama we-3m, kunye nomthamo wamanzi weelitha ezili-100 ngomzuzu, ixesha lovavanyo ngumzuzu omnye ngemitha yesikwere ubuncinane imizuzu emi-3.

Uvavanyo lokukhusela impembelelo (IK)

Imigangatho yovavanyo lwe-IK: I-IEC 62262 ichaza indlela ekufuneka kuvavanywe ngayo ii-enclosures kwii-IK ratings ezichazwa njengenqanaba lokhuseleko olunikezelwa zii-enclosures kwimpembelelo yangaphandle yoomatshini.

I-IEC 60598-1 (IEC 60529) ichaza indlela yovavanyo esetyenziselwa ukwahlula nokulinganisa inqanaba lokhuseleko olunikezelwa yi-enclosure ngokuchasene nokungena kwezinto eziqinileyo ezinobukhulu obahlukeneyo ukusuka kwiminwe nezandla ukuya eluthulini olucolekileyo kunye nokhuseleko ekungeneni kwamanzi ukusuka ekuweni kwamaconsi ukuya kwi-water jet enoxinzelelo oluphezulu.

I-IEC 60598-2-3 yiMigangatho yeHlabathi yeZibane zeNdlela nezeSitalato.

Izilinganiso ze-IK zichazwa njenge-IKXX, apho "XX" linani eliqala kwi-00 ukuya kwi-10 elibonisa amanqanaba okhuseleko olunikezelwa ziindawo zombane (kuquka ii-luminaires) kwiimpembelelo zangaphandle zoomatshini. Isikali sokulinganisa se-IK sichaza amandla endawo yokuvala ukumelana namanqanaba amandla empembelelo alinganiswa kwiijoules (J). I-IEC 62262 ichaza indlela indawo yokuvala ekufuneka ifakwe ngayo uvavanyo, iimeko zomoya ezifunekayo, ubungakanani kunye nokusasazwa kweempembelelo zovavanyo, kunye nesando sokuphazamisa esiza kusetyenziswa kwinqanaba ngalinye lovavanyo lwe-IK.
