LED (Light Emitting Diodes) ndi chitukuko chatsopano komanso chosangalatsa kwambiri chaukadaulo pamakampani owunikira, omwe adawonekera posachedwa ndipo adatchuka pamsika wathu chifukwa cha zabwino zake - kuunikira kwapamwamba, moyo wautali komanso kupirira - Zowunikira zochokera paukadaulo wa semiconductor P. ndipo N imakhala ndi moyo wautali wopitilira 20 kuposa nyali za fulorosenti kapena zowunikira.Izi zimathandiza ife mosavuta lembani ambiri ubwino waKuwala kwa LED.

Ma diode otulutsa kuwala ndi chinthu chofunikira chomwe chimagwiritsidwa ntchito pamagetsi kwazaka zambiri, koma posachedwapa adatchuka chifukwa cha ma LED amphamvu kwambiri, opatsa kuwala kokwanira kuti agwiritsidwe ntchito m'malo mwa nyali za mercury fluorescent, nyali za incandescent kapena zomwe zimatchedwa fulorosenti yopulumutsa mphamvu. mababu.

Panthawiyi, pali magwero a LED ndi ma modules omwe alipo pamsika, omwe ali olimba kwambiri kuti agwiritsidwe ntchito ngati kuyatsa kwachitukuko monga kuyatsa kwa msewu kapena paki, komanso kuunikira kwa zomangamanga za nyumba zamaofesi, mabwalo a masewera ndi milatho.Zimakhalanso zothandiza ngati gwero loyamba la kuwala m'mafakitale opangira zinthu, nyumba zosungiramo katundu ndi malo ogwira ntchito.

M'makina a LED omwe akulowa m'malo mwa kuunikira wamba, nyali zomwe zimagwiritsidwa ntchito kwambiri ndi LED SMD ndi COB yomwe imatchedwanso Chip LEDs zotuluka kuchokera ku 0.5W mpaka 5W zowunikira m'nyumba komanso kuchokera ku 10W - 50W zogwiritsira ntchito mafakitale.Kotero, kodi kuyatsa kwa LED kuli ndi ubwino wake?Inde, komanso ili ndi malire ake.Ndiziyani?

Ubwino wa kuyatsa kwa LED

Moyo wautali wautumiki- ndi chimodzi mwazabwino kwambiri za nyali za LED.Ma LED omwe amagwiritsidwa ntchito mumtundu woterewu amakhala ndi ntchito yabwino kwambiri ndipo motero amatha kugwira ntchito kwa zaka 11 poyerekeza ndi nyali zopulumutsa mphamvu zokhala ndi moyo wautumiki osakwana chaka chimodzi.Mwachitsanzo, ma LED omwe akugwira ntchito maola 8 pa tsiku adzakhala pafupifupi zaka 20 za moyo wautumiki, ndipo pambuyo pa nthawiyi, tidzakakamizika kusintha kuwala kwatsopano.Kuphatikiza apo, kuyatsa ndi kuzimitsa pafupipafupi sikukhala ndi vuto lililonse pa moyo wautumiki, pomwe kumakhala ndi zotsatirapo ngati mtundu wakale wa kuyatsa.

Kuchita bwino - Ma LED ndi omwe amagwiritsa ntchito mphamvu zochepa kwambiri (magetsi) kuposa ma incandescent, fluorescent, meta halide kapena mercury nyali, mkati mwa kuwala kowala kwa 80-90% pakuwunikira kwachikhalidwe.Izi zikutanthauza kuti 80% ya mphamvu zomwe zimaperekedwa ku chipangizocho zimasinthidwa kukhala kuwala, pamene 20% imatayika ndikusandulika kutentha.Kuchita bwino kwa nyali ya incandescent kuli pamlingo wa 5-10% - kokha kuchuluka kwa mphamvu zomwe zimaperekedwa kumasinthidwa kukhala kuwala.

Kukana kukhudzidwa ndi kutentha - mosiyana ndi kuunikira kwachikhalidwe, ubwino wa kuyatsa kwa LED ndikuti mulibe filaments kapena magalasi, omwe amakhudzidwa kwambiri ndi kuwomba ndi kuphulika.Kawirikawiri, pomanga kuwala kwapamwamba kwa LED, mapulasitiki apamwamba ndi ma aluminiyamu amagwiritsidwa ntchito, zomwe zimapangitsa kuti ma LED azikhala olimba komanso osagwirizana ndi kutentha kochepa komanso kugwedezeka.

Kutumiza kutentha - Ma LED, poyerekeza ndi kuunikira kwachikhalidwe, amapanga kutentha pang'ono chifukwa cha ntchito yawo yapamwamba.Izi kupanga mphamvu zambiri kukonzedwa ndi kusandulika kuwala (90%), amene amalola mwachindunji munthu kukhudzana ndi gwero la kuunikira LED popanda kukhudzana kuwotcha ngakhale patapita nthawi yaitali ntchito yake ndi kuwonjezera pa kukhudzana ndi moto, zomwe zitha kuchitika m'zipinda zomwe
kuyatsa kwa mtundu wakale kumagwiritsidwa ntchito, komwe kumatenthetsa mpaka madigiri mazana angapo.Pachifukwa ichi, kuunikira kwa LED ndikokondera kwa katundu kapena zida zomwe zimakhudzidwa kwambiri ndi kutentha.

Ecology - ubwino wa kuunikira kwa LED ndikuti ma LED alibe zinthu zoopsa monga mercury ndi zitsulo zina zoopsa kwa chilengedwe, mosiyana ndi nyali zopulumutsa mphamvu ndipo ndi 100% zobwezeretsedwa, zomwe zimathandiza kuchepetsa carbon dioxide. mpweya.Ali ndi mankhwala omwe amachititsa kuti kuwala kwake kukhale (phosphor), komwe sikuvulaza chilengedwe.

Mtundu - Muukadaulo wa LED, timatha kupeza mtundu uliwonse wowunikira.Mitundu yoyambira ndi yoyera, yofiira, yobiriwira ndi yabuluu, koma ndi teknoloji yamakono, kupita patsogolo kwapita patsogolo kotero kuti tikhoza kupeza mtundu uliwonse.Dongosolo lililonse la LED RGB lili ndi magawo atatu, chilichonse chomwe chimapereka mtundu wosiyana ndi mtundu wa RGB palette - wofiira, wobiriwira, wabuluu.

Zoipa

Mtengo - Kuunikira kwa LED ndikokwera mtengo kwambiri kuposa magwero achikhalidwe.Komabe, ndikofunika kukumbukira kuti pano nthawi ya moyo ndi yotalika kwambiri (zaka 10) kusiyana ndi mababu a nthawi zonse ndipo nthawi yomweyo imagwiritsa ntchito mphamvu zocheperapo kangapo kusiyana ndi mtundu wakale wa kuunikira.Pogwiritsa ntchito gwero limodzi lowala la LED lamtundu wabwino, timakakamizika kugula min.Mababu 5-10 amtundu wakale, zomwe sizingabweretse kupulumutsa kwa chikwama chathu.

Kutentha kwa kutentha - Kuwala kwa ma diode kumadalira kwambiri kutentha komwe kumayendera.Pa kutentha kwakukulu pamakhala kusintha kwa magawo omwe akudutsa muzinthu za semiconductor, zomwe zingayambitse kutentha kwa module ya LED.Nkhaniyi imakhudza malo okhawo ndi malo omwe amawonjezedwa ndi kutentha kwambiri kapena kutentha kwambiri (zitsulo zachitsulo).
