LED (Chiedza Emitting Diodes) ndiyo itsva uye inonakidza kufambira mberi kwetekinoroji muindasitiri yekuvhenekesa, iyo yakaonekwa nguva pfupi yadarika uye yakawana mukurumbira mumusika wedu nekuda kwezvakanaka zvayo - kuvhenekera kwemhando yepamusoro, hupenyu hurefu uye kutsungirira - Zviedza zvinobva pane semiconductor tekinoroji P. uye N ine hupenyu hwesevhisi hunosvika ka20 kupfuura marambi efluorescent kana incandescent.Izvi zvinotibvumira kunyora nyore nyore akawanda mabhenefiti eMwenje we LED.

Chiedza-emitting diodes chinhu chakakosha chinoshandiswa mumagetsi kwemakore mazhinji, asi nguva pfupi yadarika vakawana mukurumbira nekuda kwemagetsi emagetsi ma LED, achipa mwenje wakasimba zvakakwana kuti ushandiswe sechinotsiva mercury fluorescent mwenje, incandescent mwenje kana inodaidzwa kunzi simba rekuchengetedza fluorescent. bulbs.

Panguva ino, kune masosi e LED uye ma modules anowanikwa pamusika, ayo akasimba zvakakwana kuti ashandiswe semwenje wezvivakwa senge mugwagwa kana kupaka mwenje, uye kunyangwe mwenje wekuvaka wezvivakwa zvehofisi, nhandare nemabhiriji.Ivo zvakare vanoratidza kuti vanobatsira seyokutanga sosi yemwenje mukugadzira zvidyarwa, matura uye nzvimbo dzehofisi.

MumaLED masisitimu achitsiva mwenje wakajairwa, marambi anonyanya kushandiswa iLED SMD neCOB inonziwo Chip LEDs ine zvinobuda kubva pa0.5W kusvika 5W yekuvhenekesa mumba uye kubva pa10W - 50W yekushandisa mumaindasitiri.Naizvozvo, ane LED mwenje zvakanakira ayo?Hongu, asiwo ine painogumira.Ndezvipi?

Zvakanakira mwenje we LED

Hupenyu hurefu hwebasa- ndeimwe yemabhenefiti makuru emwenje e LED.Ma LED anoshandiswa mumhando iyi yekuvhenekesa ane basa repamusoro uye anogona kushanda kwemakore anosvika gumi nerimwe kana zvichienzaniswa nemarambi ekuchengetedza simba ane hupenyu hwesevhisi isingasviki gore.Semuenzaniso, ma LED anoshanda maawa masere pazuva achagara kweanenge makore makumi maviri ehupenyu hwebasa, uye chete mushure menguva iyi, isu tichamanikidzwa kutsiva mwenje mutsva.Pamusoro pezvo, kudzima nekudzima nguva nenguva hakuna kukanganisa hupenyu hwesevhisi, nepo kune mhedzisiro yakadaro kana kune yekare mhando o mwenje.

Kubudirira - LEDs pari zvino ndiyo inonyanya kushandisa simba rekushandisa simba shoma (magetsi) kupfuura incandescent, fluorescent, meta halide kana mercury marambi, mukati mechiedza chinopenya che80-90% chekuvhenekera kwechinyakare.Izvi zvinoreva kuti 80% yesimba rinopihwa kune mudziyo rinoshandurwa kuita mwenje, nepo 20% inorasika uye inoshandurwa kuita kupisa.Kubudirira kwemwenje we incandescent iri pa 5-10% level - chete iyo yakawanda yesimba rinopiwa rinoshandurwa kuva chiedza.

Kupokana nekukanganisa uye tembiricha - kusiyana nekuvhenekesa kwechinyakare, mukana wemwenje we LED ndeyekuti haina chero mafilaments kana magirazi maficha, ayo anonzwa zvakanyanya kuvhuvhuta nemapupu.Kazhinji, mukuvaka kwemhando yepamusoro yemwenje ye LED, mapurasitiki emhando yepamusoro uye zvikamu zvealuminium zvinoshandiswa, izvo zvinoita kuti ma LED agare akasimba uye anopesana nekudziya kwakadzika uye kudengenyeka.

Kutamisa kupisa - ma LED, achienzaniswa nemwenje wechinyakare, anogadzira zvishoma zvekupisa nekuda kwekuita kwavo kwepamusoro.Iyi kugadzirwa kwesimba kunonyanya kugadziriswa uye kushandurwa kuita chiedza (90%), iyo inobvumira kutarisana kwevanhu zvakananga nekwakabva kuvhenekera kwe LED pasina kuratidzwa kwekupisa kunyange mushure menguva yakareba yebasa rayo uye nekuwedzera kunogumira pakuonekwa nemoto, izvo zvinogona kuitika mumakamuri umo
kuvhenekera kwerudzi rwekare kunoshandiswa, kunopisa kusvika kumadhigirii mazana akawanda.Nechikonzero ichi, kuvhenekerwa kwe LED kwakanakira zvinhu kana zvishandiso zvinonyanya kunzwa tembiricha.

Ecology - mukana wekuvhenekesa kwe LED inyaya yekuti ma LED haana zvinhu zvine chepfu senge mercury nedzimwe simbi dzine njodzi kune zvakatipoteredza, mukupesana nemarambi ekuchengetedza simba uye ari 100% kudzokororwa, izvo zvinobatsira kuderedza carbon dioxide. zvinobuda.Izvo zvine makemikari emakemikari anokonzera ruvara rwechiedza chayo (phosphor), iyo isingakuvadzi kune zvakatipoteredza.

Ruvara - Mu LED tekinoroji, isu tinokwanisa kuwana yega yega mwenje mwenje ruvara.Mavara ekutanga machena, tsvuku, girini uye bhuruu, asi nehunyanzvi hwanhasi, kufambira mberi kwakakwira zvekuti tinogona kuwana chero ruvara.Yese yega yega LED RGB system ine zvikamu zvitatu, chimwe nechimwe chinopa rumwe ruvara kubva kune RGB palette ruvara - tsvuku, girini, bhuruu.

Zvakaipa

Mutengo - Mwenje ye LED inodhura mari yekudyara pane yechinyakare mwenje masosi.Zvisinei, zvakakosha kuyeuka kuti pano hupenyu hurefu kwenguva refu (kupfuura makore gumi) kupfuura yenguva dzose mabhururu emwenje uye panguva imwechete iyo inoshandisa simba rakapetwa kakawanda kudarika rudzi rwekare rwechiedza.Panguva yekushanda kweimwe LED chiedza sosi yemhando yakanaka, taizomanikidzwa kutenga min.5-10 ma bulbs emhando yekare, izvo zvingasaita kuti tive nekuchengetwa kwechikwama chedu.

Temperature sensitivity - Hunhu hwekuvhenekesa kwedhiodhi hunoenderana zvakanyanya neambient inoshanda tembiricha.Pakupisa kwepamusoro kune shanduko mumiganhu yezvino ichipfuura nepakati semiconductor zvinhu, izvo zvinogona kutungamirira mukupisa kunze kwe LED module.Nyaya iyi inobata chete nzvimbo nenzvimbo dzakafumurwa nekukasira kuwedzera kwetembiricha kana kupisa kwakanyanya (simbi dzesimbi).
