Ngaphambi kokuxoxa ngezibani ezikhulayo ze-LED, singaxoxa ngezibani ezikhanyisayo ze-LED ezisebenzisa ubuchwepheshe obufanayo ngokombono wansuku zonke.

Ngemva kokufika kwe-LED, cishe 'ishaya' izibani ezivamile ze-fluorescent emakethe, kodwa abantu abaningi bakhononda ngokuthi izibani ze-LED abazisebenzisayo ekhaya ziphuka ngemva kwezinyanga ezimbalwa zokusetshenziswa, futhi isikweletu samandla sibiza kakhulu kunangaphambili, ngakho-ke kungcono ukuthenga izibani zangaphambilini.

Uma abathengisi bephromotha, bonke bathi i-LED iyonga amandla, kodwa isimo sangempela asibonakali sinjalo. Ingabe konke lokhu ukukhangisa okungamanga kwabathengisi?

Amalambu E-LED Awonga Kakhulu Futhi Ayinobungane Imvelo. Ingabe Kunjalo Ngempela?

Ngombono, ukwethulwa kwemikhiqizo emisha kuzoba ngcono kunemikhiqizo emidala, kodwa abantu abaningi bathi izibani ze-LED azilungile njengezibani zangaphambili, zihlala ziphuka ngezikhathi ezithile, futhi zisebenzisa amandla amaningi. Ingabe kunjalo ngempela?

Amazwe emhlabeni jikelele akugqugquzela ngamandla ukusetshenziswa kwezibani ze-LED. Ngoba izibani zendabuko ezifana nezibani ze-incandescent nezibani ze-fluorescent zizodala ukungcoliswa noma ukuchithwa kwamandla lapho kusebenza noma kukhiqizwa.

Ochwepheshe baqhathanisa amalambu e-incandescent, amalambu e-fluorescent, amalambu okonga amandla, namalambu e-LED. Singafunda kulokhu ukuthi uma kuqhathaniswa nezibani ze-incandescent nezibani ezivamile ze-fluorescent, ama-LED awanayo i-mercury, i-lead, nezinye izakhi ezingcolisa imvelo. Basebenzisa amandla amsulwa e-DC ukugwema ukucwayiza okubangelwa amandla e-AC angazinzile, futhi abanayo imisebe ye-ultraviolet ne-infrared.

Kusukela ekuhlaziyweni kwedatha, singabona ukuthi mayelana nokusetshenziswa kwamandla onyaka, ama-LED anokusetshenziswa kwamandla okuphansi kakhulu, izibani ze-incandescent zinamandla asetshenziswa kakhulu, futhi izibani ze-fluorescent ziphakathi.

Ngokungeziwe ekuqhathaniseni okungenhla kwedatha yesibani ehlukene, abacwaningi benze ukuhlaziya kokuhlola kumalambu e-fluorescent ajwayelekile (36W) namalambu e-LED (18W). Ukuze kuqinisekiswe ukuthi idatha ingokoqobo kakhulu, kwasetshenziswa amalambu angu-5,500 ohlobo ngalunye, futhi ukuhlola kwenziwa ngokuvumelana nesikhathi sokukhanyisa saminyaka yonke samahora angu-2,000. Ngokubuka nje kokusetshenziswa kwamandla, izibani ezivamile ze-fluorescent zisebenzisa ugesi ongu-45W ngehora ngamandla afanayo, kuyilapho izibani ze-LED zisebenzisa i-18W ngehora, okusindisa u-27W kagesi ngehora uma kuqhathaniswa nezibani ezijwayelekile ze-fluorescent, okulingana no-60% wokonga amandla.

Uma ucabangela ukonga amandla nokonga izindleko, kufanele ukhethe izibani ze-LED ezikhulayo.

Kodwa! Kungani izibani ze-LED zakuqala zibe nempilo yesevisi emfushane kakhulu? Ingabe kuyinkulumo-ze engamanga eyenziwa ngabathengisi?

Kusukela ekuqhathaniseni le datha engenhla, singabona ukuthi ama-LED awonga amandla kakhulu. Nokho abanye abasebenzisi benethiwekhi bathe amalambu e-LED awathenge ngo-2017 awakwazanga ukusebenza isikhathi esingangesigamu sonyaka, adla ugesi omningi. 

Ake sikhulume kabanzi nge-grow light njengesibonelo ukuze sibone ukuthi yini engabangela le nkinga.

Esithombeni, indawo yokukhanya yesibani esikhulayo yi-LED (obomvu nokumhlophe). Isizathu esiyinhloko sempilo emfushane yesevisi yezibani ze-LED ezikhulayo emakethe ukuthi i-LED inokubola kokukhanya, okubangela ukubola kwayo kokukhanya. Kunezici eziningana. 

Okokuqala, ama-chips asetshenziswa abathengisi ekukhiqizeni izibani ze-LED awekhwalithi embi. Uma sithenga ukukhanya sisebenzisa ama-LED aphansi, ama-chip azoba nempilo yesevisi emfushane ngenxa yokubola kokukhanya ngesikhathi sokusetshenziswa. Ngakho-ke kukhona amaphuzu ambalwa okufanele uwaqaphele:

• Khetha umkhiqizo ozuze imiphumela embonini yokukhanyisa izitshalo

  
  

• Qaphela ukuthi ukukhanya okukhulayo kumakwe ngemodeli namapharamitha we-chip esetshenzisiwe

  
  

• Hlola isitifiketi sokuqinisekisa somkhiqizi wokukhanya okukhulayo

Okwesibili, izibani ze-LED zizwela ikakhulukazi othulini, futhi uthuli oluncane luzokwenza ukuthi ibhodi lesifunda liphule. Abathengisi abaningi bakuthola kunzima ukufeza iworkshop engenalo uthuli phakathi nenqubo yokukhiqiza, ngakho-ke kuzoba nothuli oluvalwe kungqimba lokuvikela olungangeni manzi. 

Noma ngesikhathi sokusetshenziswa, inhlabathi esemoyeni ithola 'isiphazamisi' kungqimba olungangenwa amanzi, ingene kuyo bese idala ukuzungeza okufushane. Okungenhla yizo zonke izizathu zokuthi kungani izibani ze-LED zikhula ngokuzumayo. Izibani ezikhulayo zivame ukusetshenziswa ezindlini zokugcina izithombo noma ezindaweni ezingaphandle, lapho umswakama uphezulu noma kungase kube khona ukuthintana namanzi, ngakho-ke udinga ukunaka isilinganiso se-IP somkhiqizo. 

Ngisho noma kunamanzi ngaphezulu ngaphansi kwethonya lokuchelela noma ukuhwamuka kwezitshalo, amalambu anokusebenza okungcono okungenamanzi asengakwazi ukugcina ukusebenza okukhanyayo okuphumelelayo nokuzinzile. 

Isilinganiso se-IP sihlanganisa IP65/IP66/IP68. Njengamanje, ukuvimbela amanzi okujwayelekile kwezibani ezikhulayo kutholakala ngongqimba lwe-silicone engangeni manzi, okuyindlela ephakathi emfanekisweni ongezansi. Le ndlela ingaba manzi ngaphandle kokuthinta i-luminescence.

Ukwakhiwa kwezibani nakho kuyisihluthulelo sokuphila. Maningi amandla ahlukene emithombo yokukhanya emakethe. Lapho i-wattage iphakeme, isibani sikhanya kakhulu. Amandla ahlukene adinga ukuchithwa kokushisa okuhlukile. Amanye amalambu okukhulisa ama-LED asebenzisa ukukhishwa kokushisa okushibhile ukuze kuncishiswe izindleko futhi afinyeze impilo yesibani. 

Njengamanje, izindlela eziyinhloko zokukhipha ukushisa kwezibani ezikhulayo ziwukushintshwa kokushisa okubalulekile kanye nokukhipha umoya okuthuthukisiwe, ngakho abaklami bomkhiqizo kudingeka bacabangele ukwandisa indawo yokukhipha ukushisa kanye namathuba okudlula komoya. Njengegrille yensimbi engezansi, uhlangothi olulodwa luseduze nebhodi lesifunda le-LED ukuze likhulule ukushisa kahle.

Kuzokwenzekani Ngezibani Zokukhulisa I-LED Ngokuzayo?

Ngokuthuthuka komphakathi, ukusetshenziswa kwabantu kwemithombo yemvelo nakho kukhulu, futhi izinsiza ezifana nowoyela negesi yemvelo ziya ngokuya zincipha. Amazwe ahlukahlukene afuna amandla avuselelekayo namandla amasha ukuze athathe indawo yamandla alinganiselwe. Ukuvela kokukhanyisa kwe-solar LED kungaguqula ngokuqondile amandla elanga abe amandla kagesi. Manje, singathola empilweni ukuthi imikhiqizo eminingi ekhanyayo ithathelwe indawo ama-LED.

Ukusetshenziswa kwezibani zokukhulisa i-LED konga kakhulu amandla futhi kunobungani nemvelo. Ngethemba ukuthi ikhwalithi yezibani ze-LED ezikhulayo emakethe ingathuthukiswa nakakhulu.

Intengo yezibani ze-LED ezikhulayo emakethe okwamanje ihluke kakhulu, futhi ikhwalithi nayo ayilingani. Njengomthengi, unelungelo lokwazi imingcele eminingi yomkhiqizo, futhi abakhiqizi abaningi ngokwengeziwe bazimisele ukunikeza ulwazi olwengeziwe kubathengi.

Njengenye yezimboni, thina, njengezinye izinkampani eziningi, sabelana ngolwazi oluthile lochwepheshe kanye nemingcele ngokombono wefekthri ukuze sisize abathengi abaningi baqonde ukukhulisa izibani futhi sivikele ngokuhlanganyela ilungelo labathengi lokwazi.
