Ulwazi lokukhanyisa kwe-LED

I-Light Emitting Diode (i-LED) iyisetshenziswa semiconductor esiguqula ugesi ube ukukhanya. Izibani ze-LED bezilokhu zikhona kusukela ngawo-1960, kepha manje seziqala ukuvela emakethe yokuhlala yokukhanyisa isikhala. Ekuqaleni ama-LED amhlophe ayenzeka kuphela ngamaqembu “othingo lwenkosazana” ama-LED amathathu - abomvu, aluhlaza okotshani, noluhlaza okwesibhakabhaka - ngokulawula okwamanje kuye ngakunye ukuze akhiphe ukukhanya okumhlophe okuphelele. Ama-standard diode wokukhanyisa we-LED ajwayelekile ayi-18Lokhu kwashintsha ngo-1993 ngenkathi uNichia enza i-indium gallium chip eluhlaza okwesibhakabhaka enengubo ye-phosphor esetshenziselwa ukudala ukuguquguquka kwamaza okudingekayo ukukhipha ukukhanya okumhlophe kudayode eyodwa. Le nqubo ibiza kancane kunani lokukhanya okwenziwe. Ukukhanyisa okuholelekile.

I-diode ngayinye icishe ibe yi-1/4 intshi ububanzi futhi isebenzisa cishe ama-milliamps ayishumi ukusebenza cishe eshumini le-watt. Ama-LED mancane ngosayizi, kepha angaqoqwa ndawonye ngezinhlelo zokusebenza eziphakeme kakhulu. Izindawo ze-LED zidinga umshayeli ofana ne-ballast ezindaweni zohlobo lwe-fluorescent. Abashayeli bavame ukwakhiwa (njengama-ballast we-fluorescent) noma bayisiguquli se-plug sezinto eziphathwayo (plug-in). Ama-plug-in transformer avumela isibonisi ukuthi sisebenze kumandla ajwayelekile e-120 volt alternating current (AC), ngokulahleka kwamandla (okungaba ngamaphesenti ayi-15 kuye kwangama-20). Ukukhanyisa okuholelekile

Ukusebenza kohlelo lokusebenza olujwayelekile lokuhlala kwe-LED cishe kungama-lumens angama-20 nge-watt (LPW) ethile, yize ukusebenza okufika ku-100 LPW kudalwe ezindaweni zaselebhu. Ama-incandescent bulbs asebenza cishe ngama-15 LPW ne-ENERGY STAR® afanelekayo ama-compact fluorescents cishe angama-60 LPW, kuya ngohlobo lwe-wattage nohlobo lwesibani. Abanye abakhiqizi bathi ukusebenza kahle kuphakeme kakhulu kune-20 LPW; qiniseka ukuthi uhlola ukusebenza kwesistimu, okubangela ukusetshenziswa kwamandla kwazo zonke izinto. NgoDisemba 2006, uMnyango Wezamandla waseMelika wafunda ngokusebenza kwezinkanyiso ezine. Bobane bahluleka kwizicelo zabakhiqizi; isifundo sisho ukuthi abakhiqizi bathembele ezilinganisweni zokuthi i-LED ekhethekile ikhiqiza ukukhanya okungakanani, kunokuba kukhanye kangakanani ukukhanya okukhanyiswa i-LED. Ukukhanya Kwamalambu

Ama-LED angcono ekubekeni ukukhanya ohlangothini olulodwa kunama-incandescent noma ama-fluorescent bulbs. Ngenxa yokukhipha kwawo okuqondisayo, anezici ezihlukile zedizayini ezingasetshenziswa yimiklamo yobuhlakani. Izibani ze-LED zingafakwa ngaphansi kwamatafula, emaphaseji, nasezitebhisini; Ukuhlelwa okuhlanganisiwe kungasetshenziselwa ukukhanyisa igumbi. Amanzi angenawo amanzi, izakhiwo zangaphandle ziyatholakala. Abanye abakhiqizi bacabanga ukuthi izicelo ezifana nezingadi, izindlela zokuhamba, nezindawo zokuhlobisa ngaphandle kweminyango yegaraji njengezibiza kakhulu. Ukukhanya Kwamalambu

I-Led Lighting imangele kakhulu futhi ayimelani nomonakalo kunama-compact fluorescents nama-incandescent bulbs. Izibani ze-LED azikhozi. Zizwela ukushisa kakhulu; ukushisa okweqile noma ukusetshenziswa okungafanelekile kunciphisa kakhulu ukukhishwa kokukhanya nesikhathi sempilo. Ukusetshenziswa kufaka:

• Imisebenzi nokukhanya kwezibani
• Ukukhanyisa komugqa ongaphansi (ngaphansi kwekhishi amakhabethe)
• Amakani okukhanyisa / aphelile aphelile
• Ukukhanyisa isikhwama / ngaphandle / ukukhanya
• Ukukhanyisa ubuciko
• izibani Night
• Ukukhanyisa izitebhisi nezindlela zokuhamba
• Imihlobiso neminwe ephezulu
• Ama-retrofit ama-lamp Izincazelo nemigomo
