Izibane ze-LED ezineqondo elongezelelweyo lokhuseleko logqabhuko-dubulo

Kwiimeko zokunyuka kokuqhuma, iimfuno ezikhethekileyo zokhuseleko zibekwe ekukhanyeni okwenziweyo. Ukuze ugweme iingozi, izibane zifakwe kwinguqulo yobungqina bokuqhuma. Izibane zokukhanyisa ezinezibane ezikhokelwayo ziyinguqulelo yanamhlanje yeemveliso ezinjalo.

Iimpawu zoyilo

Izibane ezikhokelela ekuqhumeni zinenani leempawu zoyilo:

• eyilwe kwizinto ezichasene nomlilo;
• izindlu ezenziwe ngeplastiki yepolymer okanye iglasi ephezulu yokuqina imelana nokushisa okuphezulu;
• izinto ezibonisa intsimbi zithintela ukufudumeza;
• Isakhelo esomeleziweyo sinika amandla amakhulu.

Kukho iimpawu ezongezelelweyo zobuchwepheshe zokhuseleko oluthembeke ngakumbi kuqhushumbo:

• isekethe yombane ekhuselekileyo ngaphakathi;
• iigesi ze-inert ngaphakathi kwimeko;
• uxinzelelo lomzimba.

Ndiyabulela kwizinto ezikhethekileyo zophuhliso, izibane zigcina ingqibelelo yazo phantsi kweempembelelo zezinto zokuvelisa. Ayoyiki:

• ukungcangcazela;
• uxinzelelo;
• iindawo ezinobundlobongela;
• amaqondo obushushu aphezulu.

Iinkcukacha

Iiparameters zezibane ezikhusela uqhushumbo ziquka:

• Iiklasi zokukhusela ukuqhuma. Izibane ezikhusela uqhushumbo zohlulwe zibe ziiklasi ezi-3 ngokuxhomekeke kwindawo ezifakelwe kuyo ngokobude bexesha kunye nobukho bomxube oqhumayo weegesi:
  • iklasi 0 – kwindawo apho iigesi eziqhumayo zihlala rhoqo okanye ixesha elide;
  • iklasi 1 – kwindawo apho kukho ithuba lokufumana umxube wegesi ngexesha lokusebenza okuqhelekileyo;
  • iklasi 2 – kwindawo apho umxube wegesi ungekho okanye ubonakala ngokungaqhelekanga kwaye ixesha elifutshane.

• I- Luminous flux – ukukhutshwa kokukhanya kwiyunithi ethile yexesha, kulinganiswa kwiiLumens (Lm). Uluhlu lwamandla akhanyayo luyahlukahluka kwizibane ze-LED ukusuka kwi-200 ukuya kwi-2500 lm, ephezulu – ekhanyayo.
• Amandla sisixa samandla aguqulwa abe kukukhanya aze alinganiswe ngeeWatts (W). Ukusetyenziswa ngokubanzi, izibane ze-3-15 W ziveliswa, kwishishini – ukuya kwi-100 W.
• Amaqondo obushushu okusebenza – asusela kwisikali ngokwezidanga zeCelsius ukusuka – 60 ukuya kwi-100 kwizibane ezinokhuseleko lwepolycarbonate, ukuya kuthi ga kwi-550 xa usebenzisa iglasi ye-borosilicate enganyangekiyo.
• I-coefficient ye- Pulsation – amandla okuguquguquka ekuhambeni kokukhanya, kulinganiswe nge%. I-Flicker yezibane ze-LED 0% phantsi kweemeko ezizinzileyo zangoku.
• Ubushushu be-thermal yemithombo ye-LED yi-hue yokukhanya okumhlophe, kulinganiswe kwi-Kelvin (K). Zahlulwe zibe zishushu (2700-3500 K), zingathathi hlangothi (3500-5000 K), zibandayo (5000-6600 K). Imibala engaphezulu kwe-3500 K isetyenziswa njengezibane ezingxamisekileyo.

Iinzuzo zokusebenzisa

Izixhobo ze-LED ezinobungqina bokudubula ziyaphucuka yonke imihla kwaye zinenani leenzuzo eziphambili ngaphezulu kwefluorescent kunye ne-incandescent fixtures:

• Ukhuseleko olubanzi ngokuchasene:
  • isiphaluka esifutshane kunye nokwanda kombane kwinethiwekhi;
  • iimpembelelo, enkosi kwiglasi eyomeleleyo ye-diffuser;
  • ukutshatyalaliswa kuxinzelelo oluphezulu;
  • ukungena kokufuma kothuli kwisibane.
• Ukukhutshwa kokukhanya okuphezulu kumaxesha angama-2 ngokufanelekileyo kunezibane ze-fluorescent kunye nezibane zokugcina amandla, amaxesha angama-7 asebenza ngokufanelekileyo kunezibane ezindala ze-incandescent.
• Ukusebenza kakuhle kwamandla . Guqula umbane ube kukukhanya ngeyona ndlela iphezulu yokusebenza kakuhle. Izibane ze-LED ezidityanisiweyo kwi-luminaires zinciphisa ukusetyenziswa kwamandla ubuncinane nge-50% xa kuthelekiswa nezibane ze-fluorescent kunye ne-85% xa kuthelekiswa nezibane ze-incandescent ekukhanyeni okufanayo.
• Ubomi benkonzo eqinisekisiweyo yezibane ze- LED ziiyure ezingama-60,000, izibane ze-fluorescent zingaphantsi kwamaxesha angama-8, kwaye izibane ze-incandescent zingaphantsi kwamaxesha angama-50.
• Ukuvumelana nokusingqongileyo . Azinayo isinyithi esinetyhefu kwaye ayifuni ukulahlwa okukhethekileyo.

Isicelo

Izibane ezikhusela uqhushumbo ziyilwe ngendlela yokuba iintlantsi zingenzeki kuzo. Oku kuthetha ukuba abanako ukubangela ukuqhuma kwiivenkile zokuvelisa kunye nokuqhuma okuphezulu kunye nobungozi bomlilo, phantsi kweempembelelo zeendawo ezinobundlobongela. Ukusetyenziswa kwezibane ze-LED zokuthintela ukuqhuma:

• kwiindawo zoshishino;
• ngaphandle;
• kwizikhululo zegesi;
• zokukhanya.

Imithombo yokukhanya enobungqina bokudubula ikwimfuno kumacandelo oqoqosho apho isetyenziswa khona ngenxa yokuncipha okubonakalayo kweemeko zonxunguphalo:

• xa kutsalwa izimbiwa;
• kwishishini lomgubo;
• kwindawo yokuvelisa igesi neoli;
• kwizixhobo zombane;
• kwishishini lemichiza;
• kwi-metallurgy;
• kushishino lwamaplanga.

Iindidi zezibane ezikhusela uqhushumbo

Zonke izixhobo ziphawulwe, oonobumba u-Ex babonisa uyilo lobungqina bokudubula. Ukutyunjwa kwi-package kuphindwe kwi-instrument case okanye ipleyiti yentsimbi – i-nameplate. Ukumisela ukuba ngowuphi umthombo wokukhanya ofunekayo kumashishini athile kunye neemeko, makhe sijonge kwiindidi zezixhobo kunye nokumakisha.

Ngokwezinga lokukhusela ukuqhuma

Izibane ezikhokelela ekuqhumeni zihlulwe zibe ngamanqanaba ama-3:

• I-0 – ngakumbi into engaqhumayo (ukukhusela phantsi kweemeko eziqhelekileyo zokusebenza);
• I-1 – i-explosion-proof (ukubonelela ngokukhusela kokubili ngexesha lokusebenza okuqhelekileyo kunye kwimeko yomonakalo);
• I-2 – ukunyuka kokuthembeka (ukukhuselwa okuphuculweyo).

Ngohlobo lokhuseleko

Iimveliso zinokuba namanqaku alandelayo:

• o – ukuzaliswa kweoli yegobolondo – ukucwiliswa kwi-liquid ekhuselayo ekhusela ukutshisa;
• p – ukuzaliswa ngegesi ekhuselayo phantsi koxinzelelo – kudala indawo engabonakaliyo yokuqhuma kwi-luminaire ngokuguquguquka koxinzelelo;
• q – ukuzaliswa kwe-quartz – ayikhuseli ukuqhuma kwesibane, kodwa kuthintela ukuqhuma kwangaphandle;
• d – igobolondo elivuthayo – limelana nokuqhuma kwangaphakathi ngaphandle kokuguqulwa kwecala lokukhusela;
• e – ukukhuselwa kumaqondo aphezulu aphezulu;
• i – intrinsically ekhuselekileyo isekethe yombane – ixhasa intrinsically ukhuseleko lwangoku;
• m – i-insulation yeendawo zesibane ezikwazi ukuvutha nge-compound;
• n – uhlobo lokukhusela ukusetyenziswa ngokubanzi kunye namanyathelo okhuseleko okwandisiweyo.

Izinto ezikhethekileyo zokusebenza kwiindawo ezahlukeneyo

Izibane ezibonisa ukuqhuma ngokweempawu zomsebenzi kwiindawo ezahlukeneyo zohlulwe ngokweeklasi:

• I-1 – isetyenziswe kwimigodi;
• I-2 – isetyenziswe kwiindawo zoshishino eziqhumayo kunye nofakelo lwangaphandle;
• I-3 – ifakwe kumashishini anothuli oluqhumayo.

Izixhobo zokukhanyisa ezingenakugqabhuka ezinezibane ze-LED lolona khetho lungcono kwiindawo ezinobungozi obuninzi bokudubula. Ngombulelo kuluhlu olubanzi lweemodeli, akunzima ukukhetha isibane kuyo nayiphi na iparameters.
