Lezi zinyathelo zinganciphisa ukuchayeka okuqondile emisebeni eyingozi kuyilapho kugcinwa izinzuzo zobuchwepheshe be-LED.

4. Ucwaningo Olwengeziwe: Uphenyo lwesayensi oluqhubekayo lubalulekile ukuze uqonde imiphumela yesikhathi eside yemisebe ye-UVA ne-UVB ekhishwa ama-LED. Ucwaningo kufanele futhi lugxile ekuthuthukiseni ubuchwepheshe be-LED obunciphisa noma obuqeda ukukhishwa kwemisebe eyingozi kuyilapho lusahlinzeka ngezixazululo zokukhanyisa ezisebenza kahle nezisimeme.

Ukusabalala okukhulayo kwama-LED ezinhlelweni zokukhanyisa ezihlukahlukene kudinga ukuhlaziya okuphelele kwethonya lawo emisebeni ye-UVA ne-UVB. Imithelela yesikhathi esizayo yalobu buchwepheshe ibiza izinyathelo ezisheshayo zokuqinisekisa ukuphepha kwabantu abavezwe izibani ze-LED, ikakhulukazi kumongo wokusetshenziswa kwesikrini isikhathi eside. Ngokusebenzisa izindinganiso zokulawula ikhwalithi, ukukhuthaza ukuqwashisa kwabathengi, ukuthatha izinyathelo zokuvikela, kanye nokutshala imali ocwaningweni olwengeziwe, singasebenzisa amandla obuchwepheshe be-LED kuyilapho sivikela impilo yabantu ezingozini zemisebe ye-UVA ne-UVB.

Ngokuzibophezela okungaguquki ekuthuthukisweni kwezokuphepha nezobuchwepheshe, i-Tianhui, ibhrendi ehamba phambili embonini ye-LED, izoqhubeka nokubeka phambili ucwaningo nentuthuko ukuze ilethe imikhiqizo emisha, yekhwalithi ephezulu ye-LED ehlangabezana nezindinganiso eziphakeme kakhulu zokuphepha. Uzakwethu ukuze uthole ikusasa eliqhakazile neliphephile.

Isiphetho

Sengiphetha, ngemva kokwenza ucwaningo olunzulu ngomthelela wobuchwepheshe be-LED emisebeni ye-UVA ne-UVB, kuyabonakala ukuthi lobu buchwepheshe obusafufusa buyiguqule kakhulu indawo yemboni. Njengoba ineminyaka engu-20 yesipiliyoni esibalulekile, inkampani yethu ibihamba phambili ekusebenziseni amandla alobu buchwepheshe bezinguquko. Ngocwaningo lwethu olucophelelayo nentuthuko, asigcinanga nje ngokuzuza ukuqonda okujulile kwemiphumela yobuchwepheshe be-LED ekukhishweni kwemisebe kodwa siphinde sakha nezixazululo ezisezingeni eliphezulu ukuze sinciphise noma yiziphi izingozi ezingaba khona. Njengoba siqhubeka nokuthuthuka futhi sisungula izinto ezintsha, sihlala sizibophezele ekubekeni phambili ukuphepha nokuphila kahle kwamakhasimende ethu. Ngolwazi lwethu olubanzi nobungcweti, kuhambisana nentuthuko ehlala ikhula njalo kubuchwepheshe be-LED, siyazethemba ekuqondiseni imboni iye ekusaseni eliqhakazile neliphephile.
