Nazi izinzuzo zobuchwepheshe bokukhanyisa i-diode ekhipha ukukhanya. Ngiyethemba ukuthi lokhu kungakusiza ukuthi wazi kabanzi ngokukhanyisa kwe-LED.

1. Isikhathi Sokuphila Kokukhanya Kwe-LED:

Inzuzo ebaluleke kakhulu yama-LED uma iqhathaniswa nezixazululo zokukhanyisa zendabuko ukuthi ihlala isikhathi eside. I-LED ejwayelekile ihlala amahora okusebenza angu-50,000 kuya emahoreni okusebenza angu-100,000 noma ngaphezulu. Lokho bude obuphindwe kabili kuya kane kunezibani eziningi ze-fluorescent, i-metal halide, ngisho ne-sodium vapor. Bude obuphindwe kangu-40 kunebhalbhu evamile ye-incandescent.

2. Ukusebenza Kahle Kwamandla E-LED:

Ama-LED ngokuvamile asebenzisa amandla aphansi kakhulu. Izibalo okufanele uzibheke lapho uqhathanisa ukusebenza kahle kwamandla kwezixazululo ezahlukene zokukhanyisa zibizwa ngelinye lamagama amabili: ukusebenza kahle okukhanyayo noma ama-lumens awusizo. Lezi zinto ezimbili zichaza inani lokukhanya okukhishwe ngeyunithi ngayinye yamandla (ama-watt) asetshenziswa yibhalbhu. Ngokusho kocwaningo, amaphrojekthi amaningi okuvuselela ukukhanyisa kwe-LED aholela ekuthuthukisweni okungu-60-75% ekusebenzeni kahle kwamandla okuphelele kokukhanya kwesikhungo. Kuye ngezibani ezikhona kanye nama-LED athile afakiwe, ukonga kungaba ngaphezu kuka-90%.

3. Ukuphepha Okuthuthukisiwe ngama-LED:

Ukuphepha mhlawumbe kuyinzuzo evame ukunganakwa uma kukhulunywa ngokukhanya kwe-LED. Ingozi yokuqala uma kukhulunywa ngokukhanya ukukhishwa kokushisa. Ama-LED cishe awakhiphi ukushisa okuya phambili kuyilapho amabhalbhu endabuko afana nama-incandescent eguqula amandla angaphezu kuka-90% asetshenziswa ukuwanika amandla ngqo ekushiseni. Lokho kusho ukuthi ama-10% kuphela ezibani ezisebenzisa amandla ezikhanyisayo empeleni asetshenziselwa ukukhanya.

Ngaphezu kwalokho, ngenxa yokuthi ama-LED asebenzisa amandla amancane angasebenza kahle ezinhlelweni zikagesi ezisebenzisa amandla aphansi. Ngokuvamile lokhu kuphephile kakhulu uma kwenzeka okuthile kungahambi kahle.

4. Izibani ze-LED Zincane Ngokwemvelo:

Idivayisi yangempela ye-LED incane kakhulu. Amadivayisi kagesi amancane angaba ngaphansi kwengxenye yeshumi ye-mm eyodwa²kuyilapho amadivayisi amakhulu kagesi engase abe mancane njenge-mm². Ubukhulu bawo obuncane benza ama-LED azivumelanise kahle nenani elingenamkhawulo lezinhlelo zokukhanyisa. Ukusetshenziswa okuhlukile kwama-LED kufaka phakathi ububanzi obuhlukahlukene kusukela ezimpandeni zawo ekukhanyeni kwebhodi lesifunda kanye nezimpawu zomgwaqo kuya ekukhanyeni kwesimo sengqondo kwesimanje, izinhlelo zokusebenza zokuhlala, zezindawo zokuhweba, njalo njalo.

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

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

Mhlawumbe enye yezindlela eziphumelela kakhulu zokuqonda i-CRI ukubheka ukuqhathanisa okuqondile phakathi kokukhanya kwe-LED kanye nesisombululo sokukhanyisa sendabuko njengezibani zomusi we-sodium. Bheka isithombe esilandelayo ukuze uqhathanise futhi uqhathanise lezi zimo ezimbili:

Ububanzi bamanani angaba khona ezibani ze-LED ezahlukene ngokuvamile buphakathi kuka-65 no-95 okuyinto ebhekwa njengenhle kakhulu.
