Ukubaluleka kokuvikela ukukhuphuka kwe-LED Outdoor Lighting
Ukushaywa kombani ukukhishwa kwe-electrostatic ngokuvamile okuthwala izigidi zamavolthi ukusuka emafwini kuya phansi noma kwelinye ifu. Ngesikhathi sokudluliswa kombani, umbani ukhiqiza izinkambu zikazibuthe emoyeni, udonsela izinkulungwane zama-volts (ama-surges) entanjeni kagesi futhi ukhiqize imisinga ehamba ibanga elingamakhulu amakhilomitha. Lokhu kuhlasela okungaqondile ngokuvamile kwenzeka ezintanjeni ezingaphandle, njengezibani zomgwaqo. Izisetshenziswa ezifana namarobhothi neziteshi eziyisisekelo zikhipha ukukhuphuka. Imojula yokuvikela ukukhuphuka ibhekane ngqo nokuphazamiseka kokukhuphuka okuvela entanjeni yamandla ekugcineni kwesekhethi. Idlulisa noma imunce amandla okuhlinzwa, inciphise usongo lokwenyuka kwamanye amasekhethi asebenzayo, njengamayunithi wamandla e-AC/DC kuma-LED lighting fixtures.
Ngamandla okushayela okukhanyisa kwe-LED yangaphandle, indawo yokusebenzisa inquma ukuthi ukuvikela umbani kuyinkomba ebalulekile yokulinganisa ukusebenza kwayo. Ngakho-ke, umklamo wokuvikela umbani kufanele ucatshangelwe ekunikezeni amandla kagesi we-LED wangaphandle. Ukuthatha umjikelezo wokuvikela umbani okokufaka kwe-AC komthombo wamandla owaziwa kakhulu ngonjiniyela njengesibonelo, ukuvikelwa kombani kokokufaka kwe-AC kokuphakelwa kwamandla kubangelwa ikakhulukazi ukumunca amandla esikhashana alethwa umbani noma ukukhipha amandla umhlaba ngendlela enqunywe kusengaphambili. Gwema umthelela ekugcineni okungemuva kokunikezwa kwamandla.
Kumalambu omgwaqo we-LED, umbani udala ukukhuphuka okubangelwa intambo kagesi. Lokhu kunyuka kwamandla kudala ukukhuphuka kocingo, okungukuthi, igagasi elikhuphukayo. Ukuhlinzwa kudluliselwa ngokungeniswa okunjalo. Izwe langaphandle linokuhlinzwa. Igagasi lizodala ithiphu ku-sine wave kulayini wokudlulisa ongu-220V. Lapho ithiphu ingena ekukhanyeni komgwaqo, izolimaza isifunda sesibani somgwaqo we-LED.
Amalambu asemigwaqweni aseneminyaka eminingi ekhona. Kungani sidinga ukuthola ukuvikeleka kombani ezibani zasemgwaqweni? Eqinisweni, izibani ze-sodium ezinomfutho ophezulu kanye nezibani zendabuko ze-mercury ezisetshenziswe esikhathini esidlule zenzelwe ama-voltage aphezulu, anomphumela wokuvikela umbani. Eminyakeni yamuva, izibani ze-LED ziye zanda kakhulu. Izibani ze-LED zidinga i-voltage encane yokuhlinzeka. Ngokuvamile, ukunikezwa kwamandla kusetshenziswa ukuguqula amandla e-AC abe amandla e-DC. Lokhu kwenza isibani somgwaqo we-LED ngokwaso singabi naso isivikelo sombani, ngakho-ke imodyuli yokuvikela ukukhuphuka idinga ukuklanywa izibani zomgwaqo.
Inkomba:Izinga lokuvikela umbani lase-US lamazinga amathathu
Emazingeni Kazwelonke ase-US akhishwe ngo-2015, amazinga amathathu ezindinganiso zokuvikela umbani afakiwe. Isizathu siwukuthi lezi zigaba ezintathu zibangelwa ukuthi izizwe zaseMpumalanga nezaseNtshonalanga e-United States zihluke kakhulu. Izimayini eziphakeme zingafinyelela izikhathi ezingu-30 kuya kwezingama-40, kuyilapho izimayini eziphansi zinezikhathi eyodwa noma ezimbili kuphela. Ngakho-ke, amazinga amathathu ajwayelekile. 6kV, 10kV kanye 20kV. Lokhu futhi kuwukuvumelana nezimo kubakhiqizi be-luminaire kanye nohulumeni basekhaya. Ohulumeni basekhaya banganquma ukusebenzisa izindinganiso ezihambisanayo ngokuvumelana nezimo zangempela.
