Kuyerekeza Kuwala: Kuwala kwa LED vs Metal Halide
Kodi Kuwala kwa Metal Halide ndi chiyani:
Metal halides ndi mankhwala omwe amapangidwa pamene zitsulo ndi halogen zimagwirizana. Zimaphatikizapo zinthu monga sodium chloride (mchere) ndi uranium hexafluoride (mafuta omwe amagwiritsidwa ntchito mu zida za nyukiliya). Nyali za Metal halide zimatulutsa kuwala podutsa mphamvu yamagetsi kudzera mu kuphatikiza kwa mercury ndi gasi wachitsulo wa halide. Amagwira ntchito mofanana kwambiri ndi nyali zina zotulutsa mpweya (monga mpweya wa mercury) - kusiyana kwakukulu ndi kapangidwe ka mpweya. Kuyambitsidwa kwa nthunzi yachitsulo ya halide nthawi zambiri kumapangitsa kuti kuwalako kukhale kothandiza komanso koyenera.
Kodi Upside kwa Metal Halide Lights ndi Chiyani:
Nyali zachitsulo za halide zimakhala zowoneka bwino nthawi 3-5 kuposa mababu a incandescent ndipo zimatulutsa kuwala kwapamwamba kwambiri. Nthawi zambiri, ndipo kutengera kusakaniza makamaka zitsulo halides, ali ndi kutentha kwambiri mtundu (mpaka 5500K). Izi zikutanthauza kuti mababu achitsulo a halide amatha kukhala othandiza kwambiri pakuyika kwambiri ngati nyali zamagalimoto, zowunikira pamalo othamanga, kapena kuyatsa zithunzi. Chomwe chimawayendera bwino kwambiri ndi zitsulo zamtundu wa halide zomwe zimatuluka.
Kodi Zofooka Zazikulu Zotani mu Metal Halide Lights:
Zina mwa zoperewera pakuwunikira kwazitsulo za halide ndi izi:
Magetsi a Metal halide amakhala ndi nthawi yayitali kwambiri yotentha kuposa kuwala kulikonse pamsika. Nyali zambiri zachitsulo za halide zomwe zimagwiritsidwa ntchito m'malo osungiramo zinthu komanso malo ochitira masewera zimatenga mphindi 15-20 kuti zingofika kutentha kwanthawi zonse. Izi ndizovuta kwambiri pazifukwa zingapo:
Ayenera kugwiritsidwa ntchito kwa nthawi yayitali kuposa ma LED chifukwa samayatsa ndikuzimitsa pakufunika.
Muyenera kuyembekezera pamene mukufuna kuwala.
Nyali zitha kugwiritsidwa ntchito ngati sizikufunika (mwachitsanzo pakatsika mphindi 30) kuti asafunikire kutentha akayatsidwanso.
Magetsi a Metal halide sagwira ntchito bwino akamayendetsedwa ndi mphamvu yocheperako. Babu wapakati amakhala pafupifupi maola 6,000 mpaka 15,000 ogwirira ntchito. Kutengera babu, mutha kuwononga ndalama zomwezo poyambira ndi ma LED ndi zitsulo. Vuto ndilakuti pakapita nthawi mudzafunika kugula zitsulo zambiri (2-5) kuti zikhale zofanana ndi moyo wa LED imodzi. Ponseponse, izi zikutanthauza kuti ndalama zosamalira zokwera kwambiri pakapita nthawi.
Kodi Zofooka Zing'ono Zotani mu Metal Halide Lights:
Zina mwa zofooka zazing'ono pakuwunikira kwazitsulo za halide ndi izi:
Magetsi a Metal halide ndi omnidirectional. Kuwala kwa Omnidirectional kumatulutsa kuwala mu madigiri 360. Uku ndi kulephera kwakukulu kwadongosolo chifukwa pafupifupi theka la kuwala liyenera kuwonetsedwa ndikutumizidwa kumalo omwe akufunidwa akuwunikiridwa. Kufunika kowunikira ndikuwongoleranso kuunika kumatanthauza kuti kutulutsako sikukhala kothandiza kwambiri kwa nyali za omnidirectional chifukwa cha kutayika kuposa momwe kungakhalire kwa kuwala komweko kukanakhala kolunjika ndi chikhalidwe chake.
Komwe Kuwala kwa Metal Halide Kumagwiritsidwa Ntchito Nthawi zambiri:
Ntchito zambiri zowunikira zitsulo za halide zimaphatikizapo malo akuluakulu amasewera monga mabwalo amasewera kapena ma hockey rinks komanso kuyatsa kwapamwamba kwa nyumba zosungiramo zinthu komanso malo akulu amkati.
LED:
Kodi Light Emitting Diode (LED) ndi chiyani:
LED imayimira Light Emitting Diode. Diode ndi chipangizo chamagetsi kapena chigawo chokhala ndi maelekitirodi awiri (anode ndi cathode) momwe magetsi amayendera - makamaka mbali imodzi (kupyolera mu anode ndi kutuluka kudzera mu cathode). Ma diode nthawi zambiri amapangidwa kuchokera ku zinthu zopangira ma semiconductive monga silicon kapena selenium - zinthu zolimba zomwe zimayendetsa magetsi nthawi zina osati mwa zina (monga ma voltages ena, milingo yamakono, kapena mphamvu ya kuwala). Pamene panopa ikudutsa muzinthu za semiconductor chipangizocho chimatulutsa kuwala kowonekera. Ndizosiyana kwambiri ndi selo la photovoltaic (chipangizo chomwe chimasintha kuwala kowoneka kukhala magetsi).
Ngati mukufuna kudziwa zambiri za momwe ma LED amagwirira ntchito mutha kuwerenga zambiri za izi. Kuti muwerenge mbiri ya kuyatsa kwa LEDPano.
Chomwe Chachikulu Kwambiri Kumauni a LED ndi chiyani
Pali zabwino zinayi zazikulu pakuwunikira kwa LED:
Ma LED amakhala ndi moyo wautali kwambiri poyerekeza ndi ukadaulo wina uliwonse wowunikira (kuphatikiza LPS ndi nyali za fulorosenti koma makamaka poyerekeza ndi nyali zachitsulo za halide). Ma LED atsopano amatha kukhala maola 50,000 mpaka 100,000 kapena kupitilira apo. Nthawi yamoyo wa babu yachitsulo ya halide, poyerekeza, ndi 12-30% utali wotalika kwambiri (nthawi zambiri pakati pa maola 6,000 ndi 15,000).
Ma LED ndiwopatsa mphamvu kwambiri poyerekeza ndi ukadaulo wina uliwonse wowunikira pamalonda. Pali zifukwa zingapo zomwe zimaphatikizirapo kuti amawononga mphamvu zochepa kwambiri ngati ma radiation ya infrared (kutentha), ndipo amatulutsa kuwala molunjika (kupitilira madigiri 180 motsutsana ndi madigiri 360 zomwe zikutanthauza kuti pali zotayika zochepa kwambiri kuchokera pakufunika kowongolera kapena kuwongolera. wonetsa kuwala).
Kuwala kwapamwamba kwambiri.
Zotsika mtengo zosamalira komanso zovuta.
Zomwe Zing'onozing'ono Zoyang'ana Kuwala kwa LED:
Kuphatikiza pa zabwino zazikulu, magetsi a LED amaperekanso zinthu zingapo zazing'ono. Izi zikuphatikizapo:
Chalk: Ma LED amafunikira magawo ochepa kwambiri a nyale.
Utoto: Ma LED amatha kupangidwa kuti apange mitundu yonse yamitundu yowala yowoneka bwino popanda kugwiritsa ntchito zosefera zachikhalidwe zomwe zimafunikira ndi kuyatsa kwachikhalidwe.
Directional: Ma LED amakhala olunjika mwachilengedwe (amatulutsa kuwala kwa madigiri 180 mwachisawawa).
Kukula: Ma LED amatha kukhala ochepa kwambiri kuposa magetsi ena (ngakhale incandescent).
Kutentha: Ma LED amasinthasintha mwachangu (palibe nthawi yotentha kapena yozizira).
Kodi Kuyikira kwa Magetsi a LED ndi Chiyani?
Poganizira zam'mwamba mungaganize kuti nyali za LED ndizosaganizira. Ngakhale izi zikuchulukirachulukira, pali zosintha zingapo zomwe ziyenera kupangidwa mukasankha LED:
Makamaka, magetsi a LED ndi okwera mtengo. Mitengo yakutsogolo ya polojekiti yowunikira ya LED nthawi zambiri imakhala yayikulu kuposa njira zina zambiri. Ichi ndiye choyipa chachikulu kwambiri chomwe chiyenera kuganiziridwa. Izi zati, mtengo wa ma LED ukutsika mwachangu ndipo pamene akupitilira kulandiridwa mochuluka mtengo upitilira kutsika. Zonse zati mtengo wakutsogolo wa ma LED poyerekeza ndi nyali zachitsulo za halide zili pafupi kwambiri. Magetsi onsewa (kutengera mtundu wake ndi mawonekedwe ake) amagulitsidwa pafupifupi $10-$30 pa nyali iliyonse. Inde izi zikhoza kusintha muzochitika zonsezi kutengera kuwala komwe kumafunsidwa.
Kumene Ma LED Amagwiritsidwa Ntchito Nthawi zambiri:
Kugwiritsa ntchito koyamba kwa ma LED kunali pama board ozungulira pamakompyuta. Kuyambira pamenepo iwo akuwonjezera ntchito zawo pang'onopang'ono kuti aphatikizepo magetsi apamsewu, zikwangwani zowunikira, ndipo posachedwa, zowunikira zamkati ndi zakunja. Kuwala kwa LED ndi njira yabwino yothetsera masewera olimbitsa thupi, malo osungiramo zinthu, masukulu ndi nyumba zamalonda. Amakhalanso osinthika m'malo akuluakulu a anthu (omwe amafunikira magetsi amphamvu, ogwira ntchito pamalo okulirapo), kuyatsa kwamisewu (komwe kumapereka ubwino waukulu wamtundu kuposa magetsi otsika komanso othamanga kwambiri a sodium), ndi malo oimika magalimoto.
Kufananiza Kowonjezera Koyenera
Kodi Kusiyanitsa Pakati pa Metal Halide ndi Magetsi a LED ndi Chiyani:
Matekinoloje awiri osiyanawa ndi njira zosiyana kwambiri zopangira kuwala. Mababu a Metal halide amakhala ndi zitsulo zomwe zimasinthidwa kukhala gasi wolowera mkati mwa galasi la galasi pomwe ma LED ndiukadaulo wokhazikika wa semiconductor. Matekinoloje onsewa amatulutsa kuwala kwapamwamba kwambiri. Ma LED amatha kukhalitsa nthawi yayitali ndipo ndiukadaulo wosagwiritsa ntchito mphamvu komanso wosasamalira kwambiri. Metal halides imakhala ndi nthawi yayitali yotentha komanso moyo wamfupi koma imatulutsa kuwala kwapamwamba kwambiri ndipo ndi imodzi mwa nyali zogwira mtima kwambiri zikafika pa kutentha kwa mtundu wozizira kwambiri.
Chifukwa chiyani ma LED angachotse mababu achitsulo pabizinesi:
Nyali zina zachitsulo zimakhala ndi nthawi yayitali yotentha (mphindi 15-20) pamene kuwala kwayamba kuyatsidwa kapena ngati gwero lamagetsi lasokonezedwa. Kuonjezera apo, pali chiopsezo chochepa kuti nyali ya metal halide ikhoza kuphulika. Ngakhale izi ndizosowa ndipo pali njira zodzitetezera zomwe zimachepetsa chiopsezo, pali mwayi wovulazidwa kapena kuwonongeka chifukwa chake. Njira zodzitetezera zimaphatikizapo kusintha mababu asanafike kumapeto kwa moyo wawo komanso en-masse monga gulu (kusiyana ndi kusintha mababu amodzi omwe amalephera). Izi zikhoza kuonjezera kwambiri ndalama ndikufupikitsa kwambiri moyo wothandiza wa kuwala.
Kuonjezera apo, mababu a metal halide ndi osagwiritsa ntchito mphamvu zamagetsi. Pamwamba pa izi, ziyenera kuyendetsedwa kwa nthawi yayitali kuposa momwe zimafunikira chifukwa chofuna kutentha. Izi zonse zimatanthawuza mtengo (nthawi zambiri zimawonetsedwa ngati bilu yokwera). Ngakhale kuti mtengo wake ndi wofanana ndi wa ma LED, mababu a metal halide amangowonjezera ndalama pakapita nthawi kutengera momwe amagwirira ntchito moyenera komanso kuchuluka komwe amafunikira kusinthidwa. M'nyumba yayikulu (monga nyumba yosungiramo zinthu, malo ochitira masewera a hockey, kapena bwalo lamasewera), kusachita bwino kumeneku kudzawonjezera.
