Kunyura kwakadzika mukati mechikamu chekuvhenekesa kwe LED kunoratidza kupinda kwayo kuri kuwedzera kupfuura zvemukati zvekushandisa sedzimba nezvivakwa, kuwedzera kune ekunze uye akasarudzika emwenje mamiriro. Pakati peizvi, mwenje wemugwagwa we LED unomira pachena seyakajairwa application inoratidza kukura kwakasimba.
Zvazvakanakira zve LED Street Lighting
Magetsi emumugwagwa echinyakare anowanzo shandisa high-pressure sodium (HPS) kana mercury vapor (MH) marambi, ari mature tekinoroji. Nekudaro, zvichienzaniswa neizvi, mwenje we LED unozvirumbidza nezvakawanda zvezvakanakira:
Kushamwaridzana Nezvakatipoteredza
Kusiyana neHPS uye mercury vapor marambi, ane zvinhu zvine muchetura semekiyuri inoda kuraswa kwakasarudzika, zvigadziriso zve LED zvakachengeteka uye zvakanyanya eco-hushamwari, zvisingaise njodzi dzakadai.
High Controllability
Mwenje wemwenje we LED unoshanda kuburikidza ne AC/DC uye DC/DC simba rekushandura kuti ripe magetsi anodiwa uye azvino. Nepo izvi zvichiwedzera kuomarara kwedunhu, zvinopa kudzoreka kwepamusoro, kugonesa kukurumidza kudzima / kudzima switching, dimming, uye chaiyo ruvara tembiricha gadziriso-yakakosha zvinhu zvekushandisa otomatiki smart mwenje masisitimu. Mwenje emumigwagwa ye LED, saka, akakosha mumapurojekiti eguta rakangwara.
Kushandisa Simba Kwakaderera
Zvidzidzo zvinoratidza kuti magetsi emumigwagwa anowanzo tora chikamu che30% chebhajeti reguta remagetsi. Iko kuderera kwesimba rekushandisa kwemwenje we LED kunogona kuderedza zvakanyanya mari iyi. Zvinofungidzirwa kuti kutorwa kwepasi rose kwemwenje ye LED kunogona kuderedza kuburitswa kweCO₂ nemamiriyoni ematani.
Excellent Directionality
Zvitubu zvemwenje zvemumigwagwa zvechinyakare zvinoshaya gwara, kazhinji zvichikonzera kusavheneka kwakakwana munzvimbo dzakakosha uye kusvibiswa kwechiedza kusingadiwi munzvimbo dzisina chinangwa. Mwenje ye LED, nekutungamira kwayo kwepamusoro, inokunda nyaya iyi nekuvhenekera nzvimbo dzakatsanangurwa pasina kukanganisa nzvimbo dzakatenderedza.
High Luminous Efficacy
Kuenzaniswa neHPS kana mercury vapor marambi, maLED anopa yakanyanya kupenya efficacy, zvichireva mamwe malumens pachikamu chesimba. Pamusoro pezvo, ma LED anoburitsa yakanyanya kuderera infrared (IR) uye ultraviolet (UV) mwaranzi, zvichikonzera kushoma kupisa kupisa uye kuderedzwa kwemafuta kushushikana pachigadziriso.
Hupenyu Hwakawedzerwa
Ma LED ane mukurumbira nekuda kwekushisa kwejunction yekushanda kwakanyanya uye hupenyu hurefu. Mumagetsi emumugwagwa, ma LED arrays anogona kugara kusvika kumaawa 50,000 kana kupfuura-2-4 nguva yakareba kupfuura HPS kana MH marambi. Izvi zvinoderedza kudiwa kwekugara kuchitsiviwa, zvichiita kuti pave nekuchengetwa kwakakosha mumutengo wezvinhu uye kugadzirisa.
Maviri Makuru Mafambiro mu LED Street Lighting
Tichifunga nezve izvi zvakakosha zvakanakira, iyo yakakura-chiyero kutorwa kwemwenje ye LED mumigwagwa yemuguta yave maitiro akajeka. Nekudaro, iyi yekusimudzira tekinoroji inomiririra "kutsiva" kwakapusa kwemidziyo yekuvhenekesa yechinyakare-ishanduko yehurongwa ine maitiro maviri akakosha:
Maitiro 1: Smart Lighting
Sezvambotaurwa, maLED 'akasimba controllability anogonesa kugadzirwa kweautomated smart street lighting system. Aya masisitimu anogona kugadzirisa mwenje otomatiki zvichienderana nedata rezvakatipoteredza (semuenzaniso, ambient light, chiitiko chevanhu) pasina kupindira kwemaoko, zvichipa zvakakosha. Pamusoro pezvo, marambi emumigwagwa, sechikamu chetiweki yezvivakwa zvemadhorobha, anogona kushanduka kuita akangwara eIoT edge node, achibatanidza mabasa akaita semamiriro ekunze uye kutariswa kwemhando yemhepo kuita basa rakatanhamara mumaguta akangwara.
Nekudaro, maitiro aya anounzawo matambudziko matsva e LED streetlight dhizaini, inoda kubatanidzwa kwemwenje, magetsi ekupa, kunzwa, kutonga, uye kutaurirana mabasa mukati menzvimbo yakamanikidzwa yemuviri. Kumisikidzwa kunova kwakakosha kugadzirisa matambudziko aya, ichimaka yechipiri kiyi maitiro.
Maitiro 2: Kumira
Kumisikidzwa kunogonesa kusanganisa kusanganisa kweakasiyana hunyanzvi zvikamu ne LED streetlights, zvakanyanya kusimudzira system scalability. Kudyidzana uku pakati pehungwaru mashandiro uye kumira-mira kunofambisa kuenderera kushanduka kwe LED streetlight tekinoroji uye maapplication.
Evolution ye LED Streetlight Architectures
ANSI C136.10 Non-Dimmable 3-Pin Photocontrol Architecture
Iyo ANSI C136.10 yakajairwa inongotsigira isingadzimike kudzora zvivakwa zvine 3-pini photocontrols. Sezvo tekinoroji yeLED yakawedzera, kugona kwepamusoro uye kusabatika kwekuita kwakawedzera kudiwa, zvichidikanwa maitiro matsva nemavakirwo, akadai se ANSI C136.41.
ANSI C136.41 Dimmable Photocontrol Architecture
Ichi chivakwa chinovaka pamusoro peiyo 3-pini yekubatanidza nekuwedzera masaini ekubuda materminal. Inogonesa kubatanidzwa kwemagetsi grid sources ne ANSI C136.41 photocontrol masisitimu uye inobatanidza magetsi switch kune madhiraivha e LED, inotsigira LED kutonga uye kugadzirisa. Iyi chiyero inodzokera kumashure-inoenderana neyechinyakare masisitimu uye inotsigira isina waya kutaurirana, ichipa inodhura-inoshanda mhinduro kune akangwara emigwagwa.
Nekudaro, ANSI C136.41 ine painogumira, senge pasina rutsigiro rwekupinza sensor. Kugadzirisa izvi, mubatanidzwa weindasitiri yemwenje wepasi rose weZhaga wakaunza Zhaga Book 18 standard, ichibatanidza iyo DALI-2 D4i protocol yekugadzira mabhazi ekutaurirana, kugadzirisa matambudziko ewaya uye kurerutsa kubatanidza sisitimu.
Zhaga Book 18 Dual-Node Architecture
Kusiyana ne ANSI C136.41, iyo Zhaga standard inobvisa magetsi emagetsi (PSU) kubva pa photocontrol module, ichibvumira kuti ive chikamu chemutyairi we LED kana chikamu chakasiyana. Ichi chivakwa chinogonesa maviri-node sisitimu, apo imwe node inobatanidza kumusoro kune photocontrol uye kutaurirana, uye imwe inobatanidza kudzika kune ma sensors, ichigadzira yakazara smart streetlighting system.
Zhaga/ANSI Hybrid Dual-Node Architecture
Munguva pfupi yapfuura, a hybrid architecture inobatanidza simba re ANSI C136.41 uye Zhaga-D4i yakabuda. Inoshandisa 7-pini ANSI interface yekumusoro node uye Zhaga Bhuku 18 yekubatanidza yekudzika pasi sensor node, kurerutsa wiring uye kukwirisa ese zviyero.
Mhedziso
Sezvo LED streetlight architectures inoshanduka, vagadziri vanotarisana nehupamhi hwesarudzo dzehunyanzvi. Kumisikidzwa kunovimbisa kubatanidzwa kwakatsetseka kweANSI- kana Zhaga-inoenderana zvikamu, zvichiita kuti zvigadziriswe zvisina musono uye kufambisa rwendo rwekuenda kune akangwara e LED mwenje masisitimu emigwagwa.
