Kulowera mozama mu gawo lowunikira la LED kukuwonetsa kulowera kwake kopitilira muyeso wamkati monga nyumba ndi nyumba, kukulirakulira panja komanso mawonekedwe apadera owunikira. Mwa izi, kuyatsa mumsewu wa LED kumawoneka ngati ntchito yowonetsa kukula kwamphamvu.
Ubwino Wachilengedwe Wakuwunikira Kwamsewu wa LED
Nyali zachikhalidwe zapamsewu nthawi zambiri zimagwiritsa ntchito nyali za high-pressure sodium (HPS) kapena mercury vapor (MH), zomwe ndi matekinoloje okhwima. Komabe, poyerekeza ndi izi, kuyatsa kwa LED kuli ndi zabwino zambiri zobadwa nazo:
Wosamalira zachilengedwe
Mosiyana ndi HPS ndi nyali za mercury vapor, zomwe zimakhala ndi zinthu zapoizoni monga mercury zomwe zimafunikira kutayidwa mwapadera, zopangira za LED ndizotetezeka komanso zokomera zachilengedwe, sizikhala ndi zoopsa zotere.
High Controllability
Nyali zapamsewu za LED zimagwira ntchito kudzera pa AC / DC ndi DC / DC kutembenuka kwamagetsi kuti apereke magetsi ofunikira komanso apano. Ngakhale izi zimawonjezera kuvutikira kwa dera, zimapereka kuwongolera kwapamwamba, kumathandizira kuyatsa / kuzimitsa mwachangu, kufiyira, ndi kusintha kolondola kwa kutentha kwamitundu - zinthu zofunika kwambiri pakukhazikitsa makina owunikira anzeru. Nyali zapamsewu za LED ndizofunikira kwambiri pama projekiti anzeru akumizinda.
Kugwiritsa Ntchito Mphamvu Zochepa
Kafukufuku akuwonetsa kuti kuyatsa mumsewu nthawi zambiri kumatenga pafupifupi 30% ya bajeti yamagetsi yamatawuni. Kugwiritsa ntchito mphamvu pang'ono kwa kuyatsa kwa LED kumatha kuchepetsa kwambiri ndalama izi. Akuti kutengera magetsi amtundu wa LED padziko lonse lapansi kungachepetse mpweya wa CO₂ ndi mamiliyoni a matani.
Directionality Wabwino
Magwero apamsewu achikhalidwe alibe njira yolowera, zomwe zimapangitsa kuti pakhale kusawunikira kokwanira m'malo ofunikira komanso kuipitsidwa kwa nyali kosayenera m'malo omwe sanafune. Magetsi a LED, ndi kuwongolera kwawo kwapamwamba, amagonjetsa nkhaniyi mwa kuunikira malo otchulidwa popanda kukhudza madera ozungulira.
High Luminous Mwachangu
Poyerekeza ndi HPS kapena nyali za mercury vapor, ma LED amapereka mphamvu yowala kwambiri, kutanthauza kuti ma lumens ambiri pagawo lililonse la mphamvu. Kuphatikiza apo, ma LED amatulutsa ma radiation otsika kwambiri a infrared (IR) ndi ultraviolet (UV), zomwe zimapangitsa kuti pakhale kutentha kocheperako komanso kuchepetsa kupsinjika kwamafuta pamagetsi.
Moyo Wowonjezera
Ma LED ndi odziwika chifukwa cha kutentha kwambiri kwapamphambano komanso moyo wautali. Powunikira mumsewu, zida za LED zimatha mpaka maola 50,000 kapena kuposa - nthawi 2-4 kuposa nyali za HPS kapena MH. Izi zimachepetsa kufunika kosinthitsa nthawi zambiri, zomwe zimapangitsa kuti pakhale ndalama zambiri zakuthupi ndi kukonza.
Makhalidwe Awiri Akuluakulu mu Kuwunikira Kwamsewu wa LED
Chifukwa cha maubwino ofunikirawa, kutengera kwakukulu kwa kuyatsa kwa LED mumayendedwe akumatauni kwakhala koonekeratu. Komabe, kukweza kwaukadaulo uku sikungoyimira "kusintha" kosavuta kwa zida zowunikira zachikhalidwe - ndikusintha kwadongosolo komwe kuli ndi machitidwe awiri odziwika:
Njira 1: Smart Lighting
Monga tanena kale, kuwongolera mwamphamvu kwa ma LED kumathandizira kupanga makina owunikira anzeru mumsewu. Makinawa amatha kusintha kuyatsa potengera chilengedwe (mwachitsanzo, kuwala kozungulira, zochitika za anthu) popanda kuchitapo kanthu pamanja, zomwe zimapindulitsa kwambiri. Kuphatikiza apo, magetsi am'misewu, monga gawo lamanetiweki akumatauni, amatha kusinthika kukhala ma IoT m'mphepete mwa ma node anzeru, kuphatikiza ntchito ngati kuwunika kwanyengo ndi mawonekedwe a mpweya kuti atenge gawo lodziwika bwino m'mizinda yanzeru.
Komabe, izi zimabweretsanso zovuta zatsopano pakupanga kuwala kwa msewu wa LED, zomwe zimafuna kuphatikizika kwa kuyatsa, magetsi, zomverera, zowongolera, ndi zolumikizirana mkati mwa malo ovuta. Kukhazikika kumakhala kofunikira kuti muthane ndi zovuta izi, ndikuyika chizindikiro chachiwiri chofunikira.
Njira 2: Kukhazikika
Kukhazikika kumathandizira kuphatikiza kosasunthika kwa zida zosiyanasiyana zaukadaulo ndi nyali zapamsewu za LED, kumapangitsa kuti dongosolo lisawonongeke. Kulumikizana kumeneku pakati pa magwiridwe antchito anzeru ndi kukhazikika kumayendetsa kusinthika kosalekeza kwa ukadaulo wa LED streetlight ndi ntchito.
Kusintha kwa LED Streetlight Architectures
ANSI C136.10 Non-Dimmable 3-Pin Photocontrol Architecture
Muyezo wa ANSI C136.10 umangothandizira zomangamanga zosazimitsidwa ndi ma 3-pin photocontrols. Pamene ukadaulo wa LED udayamba kuchulukirachulukira, magwiridwe antchito apamwamba komanso ocheperako adafunidwa kwambiri, zomwe zimafunikira miyezo yatsopano ndi zomangamanga, monga ANSI C136.41.
ANSI C136.41 Dimmable Photocontrol Architecture
Zomangamangazi zimamangirira pamalumikizidwe a 3-pin powonjezera ma terminals otuluka. Imathandizira kuphatikiza magwero a gridi yamagetsi ndi makina a ANSI C136.41 owongolera zithunzi ndikulumikiza ma switch amagetsi kwa madalaivala a LED, kuthandizira kuwongolera kwa LED ndikusintha. Muyezo uwu ndi wobwerera m'mbuyo-umagwirizana ndi machitidwe achikhalidwe ndipo umathandizira kulankhulana opanda zingwe, kupereka njira yotsika mtengo yowunikira magetsi anzeru.
Komabe, ANSI C136.41 ili ndi malire, monga palibe chithandizo cha kulowetsa kwa sensa. Kuti athane ndi izi, mgwirizano wapadziko lonse lapansi wamakampani opanga zowunikira Zhaga adayambitsa muyezo wa Zhaga Book 18, kuphatikiza protocol ya DALI-2 D4i yopangira ma bus olumikizirana, kuthana ndi zovuta zamawaya komanso kuphweka kaphatikizidwe kachitidwe.
Zhaga Book 18 Zomangamanga za Dual-Node
Mosiyana ndi ANSI C136.41, Zhaga standard decouples power supply unit (PSU) kuchokera pa photocontrol module, kuti ikhale gawo la dalaivala wa LED kapena chigawo china. Zomangamangazi zimathandizira dongosolo la ma node awiri, pomwe node imodzi imalumikizana mmwamba kwa photocontrol ndi kuyankhulana, ndipo ina imagwirizanitsa pansi kwa masensa, kupanga njira yowunikira bwino pamsewu.
Zhaga/ANSI Hybrid Dual-Node Architecture
Posachedwapa, zomangamanga zosakanizidwa zophatikiza mphamvu za ANSI C136.41 ndi Zhaga-D4i zatulukira. Imagwiritsa ntchito mawonekedwe a 7-pini ANSI pama node okwera ndi maulalo a Zhaga Book 18 pama node otsika, kufewetsa mawaya ndikugwiritsa ntchito miyezo yonse iwiri.
Mapeto
Pamene mapangidwe a kuwala kwa msewu wa LED akusintha, opanga amakumana ndi mitundu ingapo yaukadaulo. Kuyimitsidwa kumatsimikizira kuphatikiza bwino kwa zigawo zogwirizana ndi ANSI- kapena Zhaga, kumathandizira kukweza kosasinthika ndikuthandizira ulendo wopita ku machitidwe anzeru owunikira a LED mumsewu.
