Ukungena okujulile engxenyeni yokukhanyisa kwe-LED kuveza ukungena kwayo okwandayo ngale kwezinhlelo zokusebenza zasendlini njengamakhaya namabhilidi, ukunwebela kuzimo zokukhanya zangaphandle nezikhethekile. Phakathi kwalokhu, ukukhanya komgwaqo we-LED kugqama njengohlelo lokusebenza olujwayelekile olubonisa ukukhula okuqinile.
Izinzuzo Ezikhona Zokukhanya Kwesitaladi Se-LED
Izibani zasemgwaqweni zendabuko ngokuvamile zisebenzisa amalambu e-high-pressure sodium (HPS) noma i-mercury vapor (MH), okuwubuchwepheshe obuvuthiwe. Kodwa-ke, uma kuqhathaniswa nalokhu, ukukhanya kwe-LED kunezinzuzo eziningi zemvelo:
Ayinandaba nemvelo
Ngokungafani ne-HPS namalambu e-mercury vapor, aqukethe izinto ezinobuthi njenge-mercury ezidinga ukulahlwa okukhethekile, izinto ezilungiswayo ze-LED ziphephile futhi zivumelana nemvelo, azifaki izingozi ezinjalo.
Ukulawulwa Okuphezulu
Izibani zasemgwaqweni ze-LED zisebenza nge-AC/DC kanye nokuguqulwa kwamandla ka-DC/DC ukuze zinikeze amandla kagesi adingekayo kanye namanje. Nakuba lokhu kwandisa inkimbinkimbi yesekethe, kunikeza amandla okulawula okuphakeme, okuvumela ukuvula/ukuvala okusheshayo, ukufiphala, nokulungiswa kokushisa kombala okunembile—izici ezibalulekile zokuqalisa amasistimu okukhanyisa ahlakaniphile azenzakalelayo. Ngakho-ke, izibani zasemgwaqweni ze-LED zibalulekile kumaphrojekthi wedolobha elihlakaniphile.
Ukusetshenziswa Kwezamandla Okuphansi
Ucwaningo lukhombisa ukuthi ukukhanya emigwaqweni kuvamise ukubala cishe u-30% wesabelomali samandla kamasipala wedolobha. Ukusetshenziswa kwamandla okuphansi kokukhanya kwe-LED kunganciphisa kakhulu lezi zindleko ezinkulu. Kulinganiselwa ukuthi ukwamukelwa komhlaba wonke kwezibani zasemgwaqweni ze-LED kunganciphisa ukukhishwa kwe-CO₂ ngezigidi zamathani.
Isiqondiso esihle kakhulu
Imithombo evamile yokukhanyisa imigwaqo ayinakho ukuqondiswa, ngokuvamile okuholela ekukhanyeni okwanele ezindaweni ezibalulekile kanye nokungcoliswa kokukhanya okungadingeki ezindaweni okungahlosiwe. Izibani ze-LED, ngokuqondisa kwazo okuphakeme, zinqoba le nkinga ngokukhanyisa izikhala ezichaziwe ngaphandle kokuthinta izindawo ezizungezile.
Ukusebenza Okukhanyayo Okuphezulu
Uma kuqhathaniswa ne-HPS noma amalambu omphunga we-mercury, ama-LED anikeza ukukhanya okuphakeme okusebenzayo, okusho ukuthi ama-lumens amaningi ngeyunithi ngayinye yamandla. Ukwengeza, ama-LED akhipha imisebe ye-infrared (IR) ephansi kakhulu (i-IR) kanye ne-ultraviolet (UV), okuholela ekushiseni kwemfucuza okuncane kanye nokunciphisa ukucindezeleka kokushisa endaweni.
Ubude bempilo Enwetshiwe
Ama-LED aziwa ngamazinga okushisa aphezulu e-junction yokusebenza kanye nempilo ende. Ekukhanyisweni komgwaqo, izinhlu ze-LED zingahlala amahora afika ku-50,000 noma ngaphezulu—izikhathi eziphindwe ka-2-4 kunezibani ze-HPS noma ze-MH. Lokhu kunciphisa isidingo sokushintshwa njalo, okuholela ekongeni okubalulekile ezindlekweni zempahla nezokulungisa.
Amathrendi Amabili Amakhulu Ekukhanyeni Kwesitaladi Se-LED
Njengoba kunikezwe lezi zinzuzo ezibalulekile, ukwamukelwa ngezinga elikhulu kokukhanyisa kwe-LED ekukhanyisweni komgwaqo wasemadolobheni sekuyindlela ecacile. Kodwa-ke, lokhu kuthuthukiswa kobuchwepheshe kumelele okungaphezu nje "kokushintsha" okulula kwemishini yokukhanyisa evamile—kuwushintsho oluhlelekile olunamathrendi amabili aphawulekayo:
Ithrendi 1: Ukukhanyisa Okukhaliphile
Njengoba kushiwo ngaphambili, ukulawuleka okuqinile kwama-LED kuvumela ukudalwa kwamasistimu okukhanyisa emigwaqweni ahlakaniphile. Lawa masistimu angalungisa ngokuzenzakalelayo ukukhanya ngokusekelwe kudatha yemvelo (isb, ukukhanya okuzungezile, umsebenzi womuntu) ngaphandle kokungenelela okwenziwa ngesandla, okuhlinzeka ngezinzuzo ezibalulekile. Ukwengeza, izibani zasemgwaqweni, njengengxenye yohleloxhumano lwengqalasizinda yasemadolobheni, zingashintsha zibe ama-smart IoT odge node, ahlanganise imisebenzi efana nesimo sezulu kanye nokuqapha izinga lomoya ukuze kudlale indima evelele emadolobheni ahlakaniphile.
Kodwa-ke, lo mkhuba uphinda ubangele izinselele ezintsha ze-LED streetlight design, edinga ukuhlanganiswa kokukhanyisa, ukunikezwa kwamandla, ukuzwa, ukulawula, kanye nemisebenzi yokuxhumana ngaphakathi kwendawo ebonakalayo ebambekile. Ukuma kuyabaluleka ukubhekana nalezi zinselele, okuphawula inkambiso yesibili ebalulekile.
Ithrendi 2: Ukumiswa
Ukuma kusiza ukuhlanganiswa okungenamthungo kwezingxenye zobuchwepheshe ezihlukahlukene nezibani zasemgwaqweni ze-LED, kuthuthukisa kakhulu ukukaleka kwesistimu. Lokhu kusebenzisana phakathi kokusebenza okuhlakaniphile nokumiswa kushayela inguquko eqhubekayo yobuchwepheshe bokukhanya komgwaqo we-LED nezinhlelo zokusebenza.
Ukuvela kwe-LED Streetlight Architectures
I-ANSI C136.10 I-Non-Dimmable 3-Pin Photocontrol Architecture
Izinga le-ANSI C136.10 lisekela kuphela izakhiwo zokulawula ezingacimeki ngezilawuli zezithombe ezingu-3-pin. Njengoba ubuchwepheshe be-LED budlanga, ukusebenza kahle okuphezulu nokusebenza okucimezeke kwakudingeka ngokwandayo, okudinga amazinga amasha nezakhiwo, njenge-ANSI C136.41.
I-ANSI C136.41 I-Dimmable Photocontrol Architecture
Lesi sakhiwo sakhela phezu koxhumano lwamaphini angu-3 ngokwengeza amatheminali okukhipha isignali. Inika amandla ukuhlanganiswa kwemithombo yegridi yamandla nezinhlelo zokulawula izithombe ze-ANSI C136.41 futhi ixhuma ukushintshwa kwamandla kumashayeli e-LED, okusekela ukulawulwa kwe-LED nokulungiswa. Leli zinga libuyela emuva-lihambisana nezinhlelo zendabuko futhi lisekela ukuxhumana okungenantambo, linikeza isixazululo esingabizi kakhulu sezibani zasemgwaqweni ezihlakaniphile.
Nokho, i-ANSI C136.41 inemikhawulo, njengokungasekeli okokufaka kwenzwa. Ukuze kubhekwane nalokhu, umfelandawonye wemboni yezibani zomhlaba wonke u-Zhaga wethule indinganiso ye-Zhaga Book 18, ehlanganisa iphrothokholi ye-DALI-2 D4i yokuklama amabhasi okuxhumana, ukuxazulula izinselele zezintambo nokwenza lula ukuhlanganisa uhlelo.
I-Zhaga Book 18 I-Dual-Node Architecture
Ngokungafani ne-ANSI C136.41, indinganiso ye-Zhaga ihlukanisa iyunithi yokuphakela amandla (i-PSU) kusuka kumojula yokulawula isithombe, ukuyivumela ukuthi ibe yingxenye yomshayeli we-LED noma ingxenye ehlukile. Lesi sakhiwo senza kube nesistimu ye-dual-node, lapho i-node eyodwa ixhuma phezulu ukuze uthole ukulawula izithombe nokuxhumana, kanti enye ixhuma phansi ukuze uthole izinzwa, yakhe uhlelo oluphelele lokukhanyisa emgwaqweni.
I-Zhaga/ANSI Hybrid Dual-Node Architecture
Muva nje, kuvele i-architecture eyingxube ehlanganisa amandla e-ANSI C136.41 kanye ne-Zhaga-D4i. Isebenzisa isixhumi esibonakalayo se-ANSI samaphini angu-7 kumanodi aphezulu kanye nokuxhumana kwe-Zhaga Book 18 kumanodi ezinzwa eziya phansi, ukwenza izintambo zibe lula futhi zisebenzise womabili amazinga.
Isiphetho
Njengoba izakhiwo ze-LED streetlight zishintsha, abathuthukisi babhekana nezinketho eziningi zobuchwepheshe. Ukumiswa kuqinisekisa ukuhlanganiswa okushelelayo kwezingxenye ezithobela i-ANSI- noma i-Zhaga, okuvumela ukuthuthukiswa okungenazihibe futhi kusize uhambo oluya kumasistimu okukhanyisa emigwaqweni e-LED ahlakaniphile.
