Isebenza kahle kangakanani i-LED?
Ubuchwepheshe be-LED bushintshe indlela esikhanyisa ngayo amakhaya ethu namabhizinisi. Akugcini nje ngokuletha ukusebenza kahle kwamandla ekukhanyeni, futhi kuthuthukisa ikhwalithi yokukhanya, kukwenze kuhambisane nezimo ezihlukahlukene. I-LED imele i-light-emitting diode, idivayisi ye-semiconductor ekhipha ukukhanya lapho ugesi udlula kuyo. Ubuchwepheshe be-LED busebenza kahle kakhulu kunezibani zendabuko ze-incandescent nezibani ze-fluorescent. Kodwa asebenza kahle kangakanani ama-LED?
Enye yezinkomba eziyinhloko zokusebenza kahle kokukhanyisa ukusetshenziswa kwamandla. Ubuchwepheshe be-LED baziwa ngokusetshenziswa kwayo okuphansi kwamandla, okwenza kube ukukhetha okuthandwayo kokukhanyisa kwezindawo zokuhlala nezokuhweba. Eqinisweni, izibani ze-LED zonga amandla afika ku-80% ngaphezulu kunezibani zendabuko ze-incandescent futhi cishe ngo-20-30% ngaphezu kwezibani ze-fluorescent. Ukwehliswa kokusetshenziswa kwamandla akwehlisi nje kuphela izikweletu zikagesi zabathengi kodwa futhi kusiza ukunciphisa kakhulu ukukhishwa kwekhabhoni, okwenza ubuchwepheshe be-LED bube inketho yokukhanyisa evumelana nemvelo.
Esinye isici esinomthelela ekusebenzeni kahle kokukhanyisa kwe-LED impilo yayo ende yenkonzo. Amalambu e-LED ahlala isikhathi eside ngokuphindwe ka-25 kunama-incandescent endabuko kanye nezikhathi eziphindwe ka-10 kunama-fluorescent. Lokhu kusho ukuthi ukukhanyisa kwe-LED akugcini nje konga amandla, kodwa futhi kunciphisa imvamisa yokushintshwa kwe-bulb, ngaleyo ndlela kunciphise izindleko zokumosha nokugcinwa kwazo. Ama-LED ama-bulb akweleta ukuphila kwawo isikhathi eside ekwakhiweni kwawo okuqinile, okuwavumela ukuthi amelane nokushaqeka, ukudlidliza, nezinga lokushisa elidlulele, okuwenza abe inketho yokukhanyisa eqinile nethembekile.
Ubuchwepheshe be-LED busebenza kahle kakhulu ngokuphuma kokukhanya. Ama-LED ama-bulb ayakwazi ukukhiqiza ukukhanya okuphezulu esebenzisa amandla amancane, aqinisekise ukuthi ugesi omningi awudlayo uguqulwa ube ukukhanya okubonakalayo. Lokhu kuhluke kakhulu ekukhanyeni kwendabuko, lapho amandla amaningi elahleka njengokushisa. Ngakho-ke, ukukhanya kwe-LED akunikezeli nje ukukhanya okungcono kuphela kodwa futhi kusiza ukudala indawo epholile futhi enethezekile, ikakhulukazi ezindaweni ezivalekile.
Ngokungeziwe ekusebenzeni kahle kwamandla, ubuchwepheshe be-LED bunikeza ezinye izinzuzo ezifaka isandla ekusebenzeni kahle okuphelele. Isibonelo, ama-LED ama-bulb akhanya ngokushesha, okusho ukuthi afinyelela ukukhanya okuphezulu ngokushesha lapho evuliwe, ngokungafani nezinye izinhlobo zokukhanyisa ezidinga isikhathi sokufudumala. Lokhu kwenza izibani ze-LED zifaneleke ikakhulukazi izinhlelo zokusebenza ezidinga ukukhanya okusheshayo nokungaguquguquki, njengamarobhothi, izibani eziphuthumayo kanye nezibani zangaphandle ezicushwe ukunyakaza.
Enye inzuzo yobuchwepheshe be-LED ukulawulwa kwayo okuhle kakhulu. Amalambu e-LED angafiphazwa futhi akhanye ngokunembile, okuvumela abasebenzisi ukuthi balungise ukuphuma kokukhanya ukuze kuhambisane nezidingo zabo ezithile. Le degree of controllability ayigcini nje ngokuthuthukisa i-ambience nokusebenza kwesikhala, kodwa futhi yonga amandla ngokunciphisa ukusetshenziswa kwamandla okuphelele kwesistimu yokukhanyisa.
Sekukonke, ubuchwepheshe be-LED busebenza kahle kakhulu mayelana nokusetshenziswa kwamandla, ukuphila isikhathi eside, ukuphuma kokukhanya nokulawula. Ukusetshenziswa kwayo okuphansi kwamandla, impilo ende, ukukhanya okuphezulu kanye nokusebenza okukhanyayo kuyenza ibe ukukhetha okuhle kakhulu kokukhanyisa uma kuqhathaniswa nezibani zendabuko ze-incandescent kanye ne-fluorescent. Njengoba isidingo sezixazululo zokukhanyisa ezonga amandla nemvelo sikhula, ubuchwepheshe be-LED kulindeleke ukuthi bubambe iqhaza elibaluleke kakhulu ekulolongeni ikusasa lokukhanyisa.
