Uvavanyo lwesibane sesitrato se-LED

Ukukhanya kwesitalato se-LED ngokuqhelekileyo kude nathi, ukuba ukusilela ukukhanya, kufuneka sithuthe zonke izixhobo eziyimfuneko kunye nezixhobo, kwaye kufuna ubugcisa ukuyilungisa. Kuthatha ixesha kunye neendleko zokugcina zinzima. Ngoko ukuvavanywa kuyinkalo ebalulekileyo. Uvavanyo lokukhanya kwesitrato se-LED kubandakanya ukukhuselwa kwamanzi okanye ukungena (IP), uvavanyo lobushushu, uvavanyo lokukhusela impembelelo (IK), uvavanyo lokuguga, njalo njalo.

Uvavanyo lokhuseleko lokungena (IP).

Inquma ukuba ukukhanya kuya kukhusela iindawo ezisebenzayo kumanzi, uthuli, okanye ukungenelela kwezinto eziqinileyo, ukugcina imveliso yombane ikhuselekile kwaye ihlala ixesha elide. Uvavanyo lwe-IP lubonelela ngomgangatho wovavanyo oluphinda-phindayo ukuthelekisa ukukhuselwa kwendawo ebiyelweyo. Ingaba i-IP rating ime njani? Idijithi yokuqala kwi-IP rating imele inqanaba lokukhusela kwizinto eziqinileyo ukusuka kwisandla ukuya eluthulini, kwaye idijithi yesibini kwi-IP rating imele inqanaba lokukhusela kumanzi acocekileyo ukusuka kwi-1mm yemvula ukuya kwi-1m yokuntywila. .

Thatha i-IP65 umzekelo, “6” ithetha ukungangeni kothuli, “5” ithetha ukukhuselwa kwiijethi zamanzi nakweyiphi na i-engile. Uvavanyo lwe-IP65 lufuna uxinzelelo lwe-30kPa kumgama we-3m, kunye nomthamo wamanzi 12.5 iilitha ngomzuzu, ubude bexesha lokuvavanya umzuzu o-1 kwimitha yesikwere ubuncinane imizuzu emi-3. Ukukhanya okuninzi kwangaphandle IP65 kulungile.

Eminye imimandla enemvula ifuna i-IP66, i-“6” ithetha ukukhuselwa kwiijethi zamanzi ezinamandla kunye nolwandle olunzima. Uvavanyo lwe-IP66 lufuna uxinzelelo lwe-100kPa kumgama we-3m, kunye nomthamo wamanzi iilitha ezili-100 ngomzuzu, ubude bexesha lokuvavanya umzuzu o-1 kwimitha yesikwere ubuncinane imizuzu emi-3.

Uvavanyo lokhuseleko lwempembelelo (IK).

Imigangatho yomlinganiselo we-IK: I-IEC 62262 ichaza indlela izivalo ekufuneka zivavanywe ngayo kumanqaku e-IK achazwa njengomgangatho wokhuselo lweendawo ezivaliweyo ngokuchasene neempembelelo zoomatshini bangaphandle.

I-IEC 60598-1 (IEC 60529) ixela indlela yovavanyo esetyenziselwa ukwahlula kunye nokulinganisa inqanaba lokhuseleko kwindawo ebiyelweyo ebonelela ngokuchasene nokungenwa kwezinto ezinobungakanani obahlukeneyo ukusuka kwiminwe kunye nezandla ukuya eluthulini olucolekileyo kunye nokukhuselwa kungenelelo lwamanzi ukusuka kumathontsi ukuya kwi ijethi yamanzi yoxinzelelo oluphezulu.

I-IEC 60598-2-3 nguMgangatho waMazwe ngaMazwe weeLuminaires zeNdlela kunye nokuKhanya kweSitalato.

Ukulinganisa kwe-IK kuchazwa njenge-IKXX, apho "i-XX" inamba ukusuka kwi-00 ukuya kwi-10 ebonisa idigri zokukhusela ezibonelelwa ngombane (kubandakanywa ne-luminaires) ngokuchasene neempembelelo zangaphandle zomatshini. Isikali sokukala se-IK sichonga ukukwazi kwendawo ebiyelweyo ukuxhathisa amanqanaba amandla empembelelo alinganiswe kwiijowuli (J). I-IEC 62262 ikhankanya indlela indawo ebiyelweyo ekufuneka ixhonywe ngayo ukuze ivavanywe, iimeko zomoya ezifunekayo, ubungakanani nosasazo lweempembelelo zovavanyo, kunye nehamile yempembelelo emayisetyenziswe kwinqanaba ngalinye lohlelo lwe-IK.
