Nazi izinzuzo zobuchwepheshe bokukhanyisa diode ukukhanya.Sethemba ukuthi lokhu kungakusiza wazi kabanzi mayelana nezibani ze-LED.

1. I-LED Light Lifespan:

Kalula inzuzo ebaluleke kakhulu yama-LED uma iqhathaniswa nezixazululo zokukhanyisa zendabuko ubude besikhathi eside bempilo.I-LED evamile ithatha amahora okusebenza angu-50,000 kuya kumahora okusebenza angu-100,000 noma ngaphezulu.Lokho kuyizikhathi ezi-2-4 ubude kuneningi le-fluorescent, i-metal halide, ngisho nezibani zomhwamuko we-sodium.Inobude obuphindwe izikhathi ezingaphezu kwezingu-40 kunesilinganiso se-incandescent bulb.

2. Ukuphumelela Kwamandla E-LED:

Ama-LED ngokuvamile asebenzisa amanani aphansi kakhulu wamandla.Izibalo okufanele uzibheke lapho uqhathanisa ukusebenza kahle kwamandla kwezixazululo zokukhanyisa ezihlukene zibizwa ngegama elilodwa kulawa amabili: ukusebenza kahle okukhanyayo noma ama-lumens awusizo.Lezi zinto ezimbili zichaza inani lokukhanya elikhishwa iyunithi ngayinye yamandla (ama-watts) asetshenziswe isibani.Ngokocwaningo, amaphrojekthi amaningi okubuyisela izibani ze-LED aphumela ekuthuthukisweni okungama-60-75% ekusebenzeni kahle kwamandla kokukhanyisa kwesikhungo.Ngokuya ngezibani ezikhona kanye nama-LED athile afakiwe, ukonga kungaba ngaphezu kuka-90%.

3. Ukuphepha Okuthuthukisiwe ngama-LED:

Ukuphepha mhlawumbe inzuzo evame ukunganakwa uma kuziwa ekukhanyeni kwe-LED.Ingozi yokuqala uma kuziwa ekukhanyeni ukukhishwa kokushisa.Ama-LED awakhiphi cishe ukushisa okuya phambili kuyilapho ama-bulb endabuko afana nama-incandescent aguqula ngaphezu kuka-90% wawo wonke amandla asetshenziselwa ukuwanika amandla ngokuqondile ekushiseni.Lokho kusho ukuthi u-10% kuphela wamandla amalambu e-incandescent asetshenziselwa ukukhanya.

Ukwengeza, ngenxa yokuthi ama-LED adla amandla amancane angasebenza ngempumelelo ezinhlelweni zikagesi ezine-voltage ephansi.Lezi ngokuvamile ziphephe kakhulu uma kukhona okungahambanga kahle.

4. Izibani ze-LED Zincane Ngomzimba:

Idivayisi yangempela ye-LED incane kakhulu.Imishini yamandla emincane ingaba ngaphansi kwengxenye yeshumi ye-mm eyodwa²kuyilapho amadivaysi amandla amakhulu asengaba mancane njenge-mm².Usayizi wabo omncane wenza ama-LED avumelane ngendlela emangalisayo nenani elingenamkhawulo lezinhlelo zokusebenza zokukhanyisa.Ukusetshenziswa okuhlukile kwama-LED kufaka phakathi i-spectrum ebanzi kusukela ezimpandeni zawo ekukhanyisweni kwebhodi lesifunda kanye nezimpawu zethrafikhi kuya ekukhanyeni kwemizwelo yesimanje, izindawo zokuhlala, izicelo zezakhiwo zentengiso, njalonjalo.

5. Ama-LED Ane-Great Color Rendering Index (CRI):

I-CRI, isilinganiso sekhono lokukhanya lokuveza umbala wangempela wezinto uma kuqhathaniswa nomthombo wokukhanya ofanele (ukukhanya kwemvelo).Ngokuvamile, i-CRI ephezulu iyisici esifiselekayo.Ama-LED ngokuvamile anezilinganiso eziphakeme kakhulu uma kuziwa ku-CRI.

Ngokunokwenzeka enye yezindlela eziphumelelayo zokwazisa i-CRI ukubuka ukuqhathanisa okuqondile phakathi kokukhanyisa kwe-LED kanye nesisombululo sokukhanyisa esivamile njengamalambu omhwamuko we-sodium.Bona isithombe esilandelayo ukuze uqhathanise futhi uqhathanise lezi zimo ezimbili:

Ibanga lamanani angaba khona ezibani ze-LED ezihlukene ngokuvamile liphakathi kuka-65 no-95 okubhekwa njengokuhle kakhulu.
