Chii Chinokonzera Iyo chena LED chip Kufa?

Vagadziri vazhinji vanongoshandisa zvinhu zvakachipa uye zvakaderera kudzikisa mutengo wemarambi kuitira kukwezva vatengi. Chiyero chekunyunyuta kwemhando nezve WHITE LED mapaneru mwenje yakakwira mumakore maviri apfuura nekuda kweizvi. Iyo mapaneru emwenje 'kumeso kutsvuka ndeimwe yacho, uye yakaipa chaizvo. Tichataura nezve zvikonzero nei Chichena chena LED chip  Kufa. Pasina imwe ado, ngatinyure mukati chaimo.

Chii chena LED chip ?

Kugadzirwa kwemwenje chena ine WHITE LEDs inogona kuitwa nenzira mbiri dzakasiyana. Nzira yeRGB ndiyo yekutanga, uye nzira yephosphor ndiyo yechipiri. Iyo phosphor nzira ndiyo inonyanya kushandiswa muchikamu chemwenje. Iyo phosphor tekinoroji inogadzira WHITE LED package inoburitsa chena mwenje nekupfeka bhuruu chena LED chip ine yero phosphor.

Kugadzirwa kwemwenje chena ine WHITE LEDs inogona kuitwa nenzira mbiri dzakasiyana. Nzira yeRGB ndiyo yekutanga, uye nzira yephosphor ndiyo yechipiri. Iyo phosphor nzira ndiyo inonyanya kushandiswa muchikamu chemwenje.

Nekungobatanidza mwenje dzvuku, girinhi, uye yebhuruu muzvikamu zvakafanira, chiedza chichena chinogadzirwa pachishandiswa nzira yeRGB.

Iyo phosphor tekinoroji inogadzira WHITE LED package inoburitsa chena mwenje nekupfeka bhuruu chena LED chip  ine yero phosphor. Iyo yero fluorescent layer inobvumira mwenje webhuruu unogadzirwa neiyo chena LED chip  kupfuura, kugadzira chiedza chichena nemusanganiswa weblues uye yellow photons.

Pamwero we chip, chiedza-emitting diode (LED) inoumbwa ne semiconductor zvinhu zvakave zvakaderedzwa kuita p-n junction. Nekushandisa bhendi rekumberi kunosangana, munhu anogona kumanikidza maerekitironi kuti afambe kubva pan-mhando conduction bhendi kuenda kup-mhando conduction bhendi. Uku kubatanidzwazve inzira yekuvhenekesa iyo, muhuwandu hwakawanda hwezviitiko, inoguma nekugadzirwa kwefoton ine wavelength inotarwa nebhendi rezvinhu.

Mushure mekuita pateni ye WHITE LED  wafer, rinotevera rakachekwa, uye munhu anofa anogadzira wafer anobatanidzwa uye anorongedzwa. Izvo zvinodiwa kubatanidza iyo WHITE LED  kune vanotungamira vachishandisa waya dzakanyanya kunaka, dzinowanzo gadzirwa negoridhe, kuitira kuti ibudise yemberi ikozvino inodiwa kuti iwane mwenje kunze kweWHITE LED.

Sei chena LED chip s Kufa?

WHITE LEDs inowanzoitika imwe yemhando mbiri huru dzekukundikana: inofambira mberi kana njodzi. Kukundikana kwe WHIT LED LED  zvinonyanya kukonzerwa nekuderera kunononoka nekufamba kwenguva kusiyana nekushanduka kamwe kamwe, kune zvishoma zvishoma. Kukundikana, mumaziso evatengesi, haisi mamiriro ehurumende-mbiri asi inzvimbo yakasarudzika pane kuenderera kwemazinga ekuita. Maererano netsvagiridzo, ziso remunhu rinongokwanisa kuona shanduko inosvika makumi matatu muzana mukupenya kwemwenje kusati kwadzikira nerambi. Nekuda kweizvi, ruzhinji rwevagadziri vanotsanangura hupenyu hwechishandiso senzvimbo iyo kubuda kwayo inopenya inodonha inowira pasi pe70 muzana yekukosha kwayaive nako pakutanga.

Zvisinei, izvi hazvirevi kuti kukundikana kunotyisa hakuzomboitiki. Chaizvoizvo, mukana wekuti chimwe chemidziyo yako chimire kushanda nemazvo pane imwe nguva inowedzera zvakaenzana nekuoma kwemamiriro ekushanda. Pane, zvisinei, matanho aunogona kutora kuti uderedze kukanganisa kwezvizhinji zvezvinhu izvi uye kuwedzera mukana wekuti chikumbiro chako chigamuchirwe.

Kukundikana kwezvinhu

WHITE LED  kushanda uye hupenyu hunoenderana nemhando yezvinhu. Electron-hole recombination inokonzeresa kuparara kwenonradiative kana zvinhu zvacho zviine zvikanganiso zvakawanda. Mazhinji machena-chiedza WHITE LEDs anogadzirwa pasafire substrates akafukidzwa neGaN. Kudhonzwa kubva pamatinji kusapindirana kunoita kuti tambo idimbuke. Kutsemuka kwakanaka kunopararira kwakatwasuka kubva kuGaN firimu kuenda kunzvimbo inoshanda, zvakonzera kuora kusiri kweradiation. Kubuda kwerambi kunodzikira sezvo kuora kusingaregi kunowedzera. Thermocycling inogona kuparadzira kukanganisa uku.

Leakage ikozvino kubva pakukanganisa kwemaitiro yakabvumira reverse-bias ikozvino kuyerera. Inotakura jekiseni kuburikidza nenzvimbo inoshanda inogona kugadzira kana kuparadzira kuremara. Defect density inodzikisira breakdown voltage, inokanganisa mashandiro.

Yakakwira ikozvino inogona kukonzera kuremara pane jenan's p-side. Kushushikana kwemagetsi kwakashatisa ultraviolet WHITE LED s kupfuura kushushikana kwekupisa. Zhuhai Tianhui Electronic Co., Ltd.   inotonhorera-chena LED yakanakira Ultra-inopenya maapplication. Iyo yepamusoro-yakaiswa mudziyo inogona kubata 2.8 A yekumberi ikozvino ye900 lm kubuda.

Kuwedzeredza WHITE LED

Kuwedzeredza WHITE LED  inogona kukanganisa kubuda uye hupenyu hwose. Nezvekupenya kwepamusoro-soro, tsanangura mudziyo senge inotonhorera-chena LED, inogona kuburitsa 900 lm pa2.8 A.

WHITE LED  zvikanganiso hazvina kuganhurirwa kune inoshanda midhiya. Epoxy encapsulate inodzivirira kufa, asi inogona kukonzera matambudziko. Iyo inonwisa zvinhu inogona kuendesa hunyoro kana caustic makemikari kune inofa munzvimbo ine hunyoro kana inoora. Corroded contacts anogona kugadzira zvikabudura kana overvoltage. Passivation inogona kuderedza mhedzisiro iyi, asi zvishandiso zvinofanirwa kuchengetedzwa munzvimbo dzinopisa, dzine hunyoro.

Kukanganisa kwemagetsi

Electromigration, inongoitika yega inokwidziridzwa nehunyoro kana mamiriro akanyorova, inogona kungoerekana yagadzira filaments kubva kune simbi senge sirivheri mupaste inoshandiswa kunamira pamusoro-inokwira LEDs kumabhodhi. Dzivisa asina-encapsulated LEDs.

WHITE LE D yakafumurwa kune yakakwira-voltage electrostatic discharge inogona kutadza kuita njodzi. Ultra-high-voltage spikes inowanzoitika. Kufamba nekamuri ine kapeti kunogona kukubhadharisa kusvika ku1.5 kV, zvichienderana nehunyoro uye shangu. Iko kuvhunduka kunogona kukunda semiconductor zvinhu zvemagetsi zvinoramba kana zvaunzwa kurufu. Kupisa kwakanyanya kwenzvimbo kubva pakubuda kunogona kupinza midhiya inoshanda, zvichikonzera kutadza kwepfupi.

KweKutenga Chena chena LED chip  Zvinotora Nguva Yakareba

Zhuhai Tianhui Electronic Co., Ltd.  ndeyemhando yepamusoro UV Vagadziri ve LED  inyanzvi muUV WHITE LED drive air sanitization, UV WHITE LED drive yekuchenesa mvura, UV WHITE LED drive kudhinda kurapa, UV White LED diode , uv   Yapamushi Moduzi , nezvimwe zvinhu. Iyo ine nyanzvi yekutsvagisa nekusimudzira uye nevashandi vekunze kuti vape vatengi neUV WHITE LED drive Arrangement, uye zvigadzirwa zvayo zvakawanawo kubvumidzwa kwevatengi kwakapararira.

Tianhui Hardware yanga iri chikamu cheUV WHITE LED drive package ine yakazara kusikwa kwakatevedzana, inowirirana mhando uye kusimba, uye yakaderera mitengo. Izvo zvikamu zvinosanganisira UVA, UVB, uye UVC kubva kupfupi kusvika kureba frequency uye yakazara UV Radiation ruzivo kubva pasi kusvika kune yakakwirira simba.
