Ungathuthukisa kanjani ukukhanya komugqa wokukhanya we-LED

Ngokuya ngohlelo oluthile kanye nekhwalithi yokukhanyisa oyifunayo, ukukhanya okuhlukile kungase kudinge ukukhanyisa kwangaphakathi. I-Lumens per watt (lm/W) iyiyunithi evamile yokulinganisa yokusebenza kahle kokukhanya kwangaphakathi. Izwakalisa ubuningi bokukhanya okukhiphayo (amalumens) okukhiqizwa ngeyunithi ngayinye yamandla kagesi (watt) asetshenzisiwe.

Ukusebenza kahle kokukhanya okuphakathi kuka-50 no-100 lm/W ngokuvamile kwamukelwa emithonjeni yokukhanyisa evamile njengama-incandescent noma ama-fluorescent ama-bulb ukuze kukhanye okuvamile kwasendlini. Ukusebenza kahle okuphezulu manje kungenzeka, noma kunjalo, njengoba ukukhanya kwe-LED kusetshenziswa kakhulu nangaphezulu. Izibani eziningi ze-LED zisebenza kahle okungenani ngama-lumens ayi-100 nge-watt ngayinye, kanti amanye amamodeli asezingeni eliphezulu angafinyelela ku-150 lumens iwathi ngayinye.
Inani elinembile lokusebenza kahle kokukhanya okudingekayo ekukhanyisweni kwangaphakathi lizohluka ngokuya ngokusetshenziswa okuhlosiwe kwesikhala, amaleveli okukhanya afunekayo, nanoma yiziphi izinjongo zokonga amandla. Ukusebenza kahle kokukhanya okuphezulu, isibonelo, kungase kube usizo ezindaweni ezidinga ukukhanya okwengeziwe, njengezindawo zokusebenza noma izindawo zokudayisa, ukuze kongiwe ukusetshenziswa kwamandla nezindleko zokusebenza. Kodwa-ke, izindawo ezinezwi elanele noma ukukhanya kwe-ambient zingadla amandla amancane ngokusebenza kahle.
Sengiphetha, izidingo ezihlukene zokukhanyisa zangaphakathi zingase zibe namazinga ahlukene okusebenza kahle kokukhanya; noma kunjalo, njengoba ubuchwepheshe be-LED buthuthuka, ukusebenza kahle okuphezulu kuya ngokuya kuba okujwayelekile futhi okufiselekayo ezixazululo zokukhanyisa zasendlini ezonga ugesi nezemvelo.

Inani lokusebenza kahle kokukhanya okudingekayo ekukhanyisweni kwangaphandle lingashintsha kuye ngohlelo lokusebenza nezimo ezizungezile. Ngenxa yobunzima obuvezwa izindawo ezingaphandle kanye nesidingo samazinga okukhanya aphezulu, ukukhanya kwangaphandle kuvame ukudinga ukusebenza kahle kokukhanya kunokukhanyisa kwangaphakathi.
Ukusebenza kahle kokukhanya okuphezulu kuvame ukudingeka ezindaweni ezingaphandle, njengezindawo zokupaka, imigwaqo, nezibani zokuphepha, ukuze kuqinisekiswe ukubonakala okufanele nokuphepha. Ngohlelo lokusebenza lwangaphandle, izibani ze-LED ngokuvamile zilwela ukusebenza kahle kuka-100 lm/W noma ngaphezulu ukuze kuncishiswe ukusetshenziswa kwamandla futhi kunikeze ukukhanya okudingekayo.
Izinto zokukhanyisa zangaphandle nazo kufanele zibhekane nezinto ezifana nokukhanya kwe-ambient, isimo sezulu, kanye nemfuneko yokusatshalaliswa kokukhanya okulinganayo, konke okungathinta izinga elincane lokusebenza kahle kokukhanya. Ngakho-ke, ukuze kufinyelelwe amazinga okukhanya afanele kuyilapho kugcinwa ukonga kwamandla futhi kwehliswa izidingo zokunakekelwa, izixazululo zokukhanyisa ngaphandle ngokuvamile zibeka phambili kakhulu ekusebenzeni kahle.

Sengiphetha, uma kuqhathaniswa nokukhanyisa kwangaphakathi, ukukhanya kwangaphandle ngokuvamile kunezidingo eziphakeme zokukhanya. Izibani ze-LED ngokuvamile zihlose ukusebenza kahle kuka-100 lm/W noma ngaphezulu ukwanelisa izimfuno zezinhlelo zokusebenza zangaphandle.

Ukusebenza kokukhanya komugqa wesibani se-LED kungaphakanyiswa ngezindlela eziningi:

1-Sebenzisa ama-LED ekhwalithi ephezulu: Ukuze uthole ukukhanya okukhiphayo okuphelele nokunemba kombala, khetha ama-LED anamandla okukhanya okuphezulu kanye nenkomba yokunikeza umbala (CRI).
2-Lungiselela idizayini: Qiniseka ukuthi umugqa wokukhanya we-LED unokuphatha okushisayo okusebenzayo okwakhelwe ngaphakathi ukuze ugweme ukushisa ngokweqile, okungafinyeza ukuphila kwama-LED nokuphuma kokukhanya.
3-Qasha abashayeli abaphumelelayo: Khetha izishayeli ze-top-notch ezinganikeza amandla angaguquki, asebenzayo kuma-LED ngenkathi yehlisa ukulahleka kwamandla futhi ithuthukisa ukuphuma kokukhanya.
4-Khetha ukuminyana kwe-LED okuphezulu: Ngokungeza ama-LED engeziwe ngobude beyunithi ngayinye, ungakhuphula ukusebenza kahle ngokuthuthukisa ukuphuma nokusabalalisa ukukhanya.
5-Sebenzisa izinto ezikhanyayo: Ukwandisa ukusetshenziswa kokukhanya nokunciphisa ukulahleka kokukhanya, hlanganisa izinto ezikhanyayo ngemuva komugqa wokukhanya we-LED.
6-Sebenzisa ama-optics asebenzayo: Ukuqinisekisa ukuthi ukukhanya okuningi kuqondiswe lapho kudingeka khona, cabanga ngokusebenzisa amalensi noma ama-diffuser ukuze ulawule isiqondiso nokusabalalisa ukukhanya.
7-Phatha izinga lokushisa lokusebenza: Ukuze ulondoloze ubude besikhathi eside nokusebenza kahle, qiniseka ukuthi umucu wokukhanya we-LED usebenza ngaphakathi kwebanga lokushisa eliphakanyisiwe.
Lawa masu angakusiza ukuthi ukhulise kakhulu ukukhanya komugqa wokukhanya kwe-LED, okuzothuthukisa ukusebenza futhi konge amandla.
