Zvakanakira uye kuipa kwemwenje we LED

Light emitting diodes (LEDs) ave achishandiswa mumagetsi eredhiyo kwenguva yakareba. Ikoko ivo vanoshandiswa, semuenzaniso, mune optical relays kana optocouplers yekusabatika chiratidzo chekufambisa pamusoro peiyo optical chiteshi. Zvishandiso zvepamba zviri kure zvinotumirawo masaini uchishandisa infrared LEDs. Magirobhu emwenje anoshandiswa kuratidza uye kuvhenekera mumidziyo yemumba uye marudzi ese emagajeti anowanzowo ma LED. A light emitting diode chinhu che semiconductor umo, kana ikozvino ichipfuura nepa pn junction, electron-hole recombination inoitika. Iyi nzira inoperekedzwa nekubuda kwemafotoni echiedza.

Pasinei nekukwanisa kubudisa chiedza, ma LED haasati ashandiswa pakuvhenekera. Kusvikira munguva pfupi yapfuura. Zvose zvakashanduka nekuuya kwezvikamu zvakapenya zvikuru, izvo zvaive zvakakodzera kugadzira zvigadzirwa zvemwenje. Kubva ipapo, tekinoroji yemwenje ye LED yakatanga kupinda muhupenyu hwedu uye ichibvisa kwete chete incandescent bulbs, asiwo iyo inonzi inochengetedza simba.

Kushandiswa kwe LED tekinoroji mumotokari

Kubudirira kwetekinoroji hakuna kucherechedzwa nevagadziri vemotokari. Ane simba uye panguva imwe chete madiki ma LEDs akaita kuti zvikwanisike kudzima mwenje wemotokari. Pakutanga vakatanga kushandiswa kupaka marambi, mabhureki mabhureki, kutendeuka, ipapo kune yakaderera matanda. Munguva pfupi yapfuura, mwenje we LED wepamusoro wakaonekwa zvakare. 

Kana pakutanga magetsi e LED akaiswa chete pamhando dzinodhura, saka munguva pfupi yapfuura, sezvo mari yetekinoroji yave yakachipa, ivo vakatanga kuoneka pamotokari dzepakati. Mumhando dzebhajeti, kushandiswa kwe LED kuchiri kungogumira kune anobatsira magetsi masosi - semuenzaniso, chinzvimbo kana mwenje unomhanya.

Asi vanoda tuning vava nemukana mutsva wekusiyanisa mota yavo kubva kune yakasara ine inoshamisa LED backlighting yepasi, logo uye manhamba. Ruvara runogona kusarudzwa kune kuravira kwako. Nerubatsiro rwema LED mitsetse, zviri nyore kujekesa trunk kana kutsiva zvachose mwenje mune kabhini.

Chigadzirwa chemwenje che LED

Chinangwa chikuru chemagadzirirwo emotokari yemotokari ndechekupa huwandu hwakanyanya hwekuvhenekera, uku uchibvisa iyo inoyevedza mhedzisiro yevatyairi vari kuuya. Hunhu, simba uye kugara kwakakosha zvakare. Tekinoroji yeLED inowedzera zvakanyanya mikana yevagadziri vemwenje.

Kunyangwe munhu mumwe chete LED isinganyanyi kupenya kupfuura uye zvakatonyanya zvakadaro, nekuda kwehukuru hwayo, seti yemakumi emhando dzema LED akadaro anogona kuiswa mumusoro. Pamwe chete vachapa chiedza chakakwana chemugwagwa. Muchiitiko ichi, kusashanda kwechimwe kana zviviri zvikamu hazvizoiti kuti kukundikana kwakakwana kwechiedza chepamusoro uye hazvizokanganisa zvakanyanya chiyero chekuvhenekera.

Yakanaka mhando ye LED element inokwanisa kushanda kwe50 zviuru maawa. Aya makore anopfuura mashanu ebasa rinopfuurira. Mukana wekukundikana kwezvikamu zviviri kana kupfuura mune rimwe mwenje wemusoro idiki zvakanyanya. Mukuita, izvi zvinoreva kuti haungambofi wakazofanira kushandura mwenje wakadaro zvachose.

Iyo magetsi emagetsi ku LED headlight haina kupihwa zvakananga kubva pane-bhodhi network, asi kuburikidza nekudzikamisa. Muchiitiko chakareruka, unogona kushandisa rectifier diode pamwe neanopikisa anodzikamisa iyo iripo inoyerera kuburikidza ne LED. Asi vagadziri vemotokari vanowanzoisa mamwe ma converter akawandisa anowedzera hupenyu hwezvinhu zve LED. 

Kudzora otomatiki kwemwenje we LED

Kusiyana nemarambi e-incandescent uye marambi ekuburitsa gasi, ayo anoratidzwa neimwe inertia, ma LED anodzima uye anodzima kanenge ipapo. Uye sezvo mwenje wemwenje wemusoro unoumbwa nekupenya kunopenya kwezvikamu zvega, izvi zvinoita kuti zvikwanise kukurumidza kugadzirisa kuvhenekera zvichienderana nemamiriro emotokari - semuenzaniso, chinja kubva pakakwirira kuenda kune yakaderera danda kana kudzima ega ega zvinhu zve LED. sekusadadisa vatyairi vemota dziri kuuya.

Zvirongwa zvakatogadzirwa izvo zvinokutendera kuti udzore mavhenekeri ekutanga, pasina kupindira kwevanhu. Mumwe wavo anoshandisa maketeni, ayo, nerubatsiro rwejini yemagetsi, anovhara chikamu che LEDs. Maketeni anodzorwa nekombuta, uye kutariswa kwekuuya kwetraffic kunoitwa nevhidhiyo kamera. Sarudzo inofadza, asi inodhura zvikuru.

Kuwedzera kuvimbisa ihurongwa umo chimwe nechimwe chine imwe photodetector inoyera kuvhenekera kwayo mukunze kwenyika. Chiedza chemusoro ichi chinoshanda mune pulsed mode. Kumhanya kwepamusoro kunokubvumira kuti ubatidze uye udzime ma LED pane frequency isingaonekwe nemeso emunhu. Iyo optical system yemwenje wemusoro wakagadzirwa. Zvinoitika kuti imwe neimwe photocell inogamuchira kunze kwekunze chete kubva kune iyo inoenderana LED inopenya. Pakarepo iyo photodetector inogadzirisa chiedza, LED inobva yadzima pakarepo. Muchisarudzo ichi, hapana komputa, kana vhidhiyo kamera, kana magetsi emagetsi emoto anodiwa. Hapana kugadzirisa kwakaoma kunodiwa. Uye zvechokwadi mutengo wakaderera zvikuru.

zvakwakanakira

1. LED zvinhu zvidiki. Izvi zvinovhura huwandu hwakawanda hwekushandisa, kuiswa uye dhizaini mikana.
2. Kuderera kwesimba rekushandisa uye kushanda kwakanyanya. Izvi zvinoderedza mutoro pane jenareta uye inochengetedza mafuta. Kushanda kwesimba kwepamusoro kuchanyanya kukosha mumotokari dzemagetsi, uko kuchachengetedza simba rebhatiri.
3. Ma LED haatombopisa, saka nhamba huru yezvikamu zve LED inogona kuiswa mune imwe mwenje wemusoro pasina njodzi yekupisa. 
4. Hupenyu hurefu hwebasa - anenge makore mashanu ekuenderera mberi kwekushanda. Kuenzanisa: marambi exenon anoshanda asingasviki maawa zviuru zvitatu, uye marambi ehalogen haawanzosvika chiuru.
5. Kuita kwepamusoro. Kukurumidza kupindura kwemarambi e LED mabhureki achienzaniswa neayo halogen anovandudza kutyaira kuchengetedza.
6. Iko kugona kugadzira malights ane automatic lighting control zvichienderana nemamiriro ezvinhu mumugwagwa.
7. High quality. Dhizaini yakavharwa inoita kuti mwenje wemusoro usapinde mvura. Iyewo haatyi kuzununguka uye kuzununguka.
8. Mwenje ye LED zvakare yakanaka kubva kune zvakatipoteredza maonero. Izvo hazvina zvinhu zvine chepfu, uye kuderedza kushandiswa kwemafuta, zvakare, kunoderedza huwandu hwemagasi ekupedza.

kutadza

1. Iko kusakosha kukuru kwemwenje ye LED ndiyo mutengo wakakwira. Kunyange zvazvo iri kuderera zvishoma nezvishoma, mitengo ichiri kuruma zvinorwadza.
2. Iyo yakaderera kupisa kupisa inochengeta girazi remwenje rinotonhorera. Izvi zvinodzivirira kunyunguduka kwechando nechando, izvo zvinokanganisa kushanda kwechiedza.
3. Dhizaini yemwenje yemusoro haina kuparadzaniswa, izvo zvinoreva kuti kana ikakundikana ichafanirwa kuchinjwa zvachose.

mhedziso

Pakati pevatyairi, chido chemwenje chexenon hachisati chapera, uye matekinoroji e LED atove akanyanya kurira. Zvakanakira mwenje we LED zviri pachena, uye hapana mubvunzo kuti nekufamba kwenguva ivo vanozove vanodhura uye vanozokwanisa kutsiva zvakakomba xenon uye halogens.

Uye munzira kune mwenje wemotokari uchishandisa laser tekinoroji. Uye mienzaniso yekutanga yakatogadzirwa. Mwenje weLaser, semwenje we LED, une hupenyu hurefu hwesevhisi, uye unopfuura iwo maererano nechiedza chekuvhenekera. Nekudaro, hapana chikonzero chekutaura nezvavo zvakakomba zvakadaro - maererano nemutengo, rimwe rakadaro remwenje rinofananidzwa nemota nyowani-yekirasi yebhajeti.
