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. Isilinganiso se-LED sithatha 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 wezibani ze-incandescent ezinikeza amandla amandla 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 e-sodium vapor. 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.
