Ndezvipi Zvinhu Zvinokanganisa AC -isina LED Mwenje Kubudirira

1. Iyo tekinoroji yekupisa kupisa Kwechiedza-emitting diode inoumbwa nePN, kana iyo yekumberi ichiyerera kubva kuPN, iyo PN knot ine kupisa kurasikirwa. Aya makoriyumu anovhenekerwa mumhepo kuburikidza nekubatanidza glue, zvinhu zvekudiridza, kupisa kunyura, nezvimwewo, uye kupenya mumhepo. Mukuita uku, chikamu chega chega chechinhu chinopikisa kupisa kudzivirira kuyerera, ndiko kuti, kushomeka kwekushisa, AC -isina LED kupisa kupikisa ndiko kukosha kwakatarwa kwakatemwa nehukuru hwechigadzirwa, chimiro uye zvinhu. Thermal resistance of the light diode is RTH (/w), uye simba rekubvisa kupisa ndiro PD (W). Panguva ino, tembiricha yePN knot inokonzerwa nekurasikirwa kwekupisa kwezvino inokwira kusvika: t () = Rth PD. PN knot tembiricha ndeye: TJ = TARTH PD, uko TA ndiyo tembiricha yepakati. Sezvo kukwira kwekushisa kwepfundo kuchaderedza mukana wekubatanidza PN, kupenya kwemaodhi anopenya kunoderera. Panguva imwecheteyo, nekuda kwekuwedzera kwekushisa kwekushisa kunokonzerwa nekurasikirwa kwekushisa, kupenya kwechiedza-emitting diode hachichapfuuriri kuwedzera nechiyero chemazuva ano, ndiko kuti, chiitiko chekupisa kwekushisa. Pamusoro pezvo, nekukwira kwekushisa kweknot, iyo peak wavelength yekupenya inonyurawo ikananga kune iyo refu wave, ingangoita 0.2-0.3nm/, iyo ndeye chena AC-isina LED nechena AC-isina LED. nekuputira iyo YAG fluorescent poda neiyo Blu-ray chip. Kukukurwa kweBlu -ray wavelength kunokonzeresa kurasikirwa neupfu nehupfu hwefluorescent kuti usimudzire wavelength, nekudaro ichideredza kupenya kwechiedza chemwenje chena ye LED, uye shanduko mukudziya kwemavara machena. Kune simba remitting diode, iyo yekutyaira ikozvino inodarika mazana emamirimita. Ikozvino density yePN knot yakanyanya kwazvo, saka kukwira kwekushisa kwePN knot kuri pachena. Pakurongedza uye maapplication, maitiro ekudzikisa kupisa kwechigadzirwa, kuitira kuti kupisa kunogadzirwa nePN knot kunogona kuburitswa nekukurumidza sezvinobvira, izvo zvisingagone kungovandudza saturation ikozvino yechigadzirwa, kuvandudza mwenje we chigadzirwa, asiwo kuvandudza kuvimbika uye hupenyu hwechigadzirwa. Kuti uderedze kupisa kwekupisa kwechigadzirwa, kusarudzwa kwezvinhu zvekurongedza kunonyanya kukosha, kusanganisira kupisa kunyura, kunamatira, nezvimwe. Kupisa kupisa kwechinhu chimwe nechimwe kunofanira kunge kwakaderera, ndiko kuti, kupisa kwekuita kwekuita kwakanaka. Chechipiri, dhizaini yekugadzira inofanirwa kuve inonzwisisika. Iyo yekupisa conductivity pakati pechinhu chimwe nechimwe inoramba ichienderana, uye iyo yekupisa conductivity pakati pezvigadzirwa zvakanaka kudzivirira kuburitsa mabhodhoro ekupisa mukupisa mukupisa. Panguva imwecheteyo, zvinodikanwa kuve nechokwadi kubva muumhizha, kupisa kunobudiswa munguva maererano nechekare-yakagadzirirwa kupisa nzira yekupisa. 2. Sarudzo yekuzadza glue Maererano nemutemo we refraction, kana chiedza chiri chiitiko kubva kune chiedza media kusvika kune chiedza sparse medium, apo chiitiko chechiitiko chinosvika pane imwe kukosha, kureva, kana kona yakakosha yakakura kudarika kona yakakosha, kuzarurwa kwakazara kuchaitika. Panyaya yeGAN yebhuruu chip, iyo refractive index yeGAN zvinhu ndeye 2.3. Kana mwenje uchipfurwa kubva kukristaro kuenda kumhepo, maererano nemutemo wekuramba, iyo yakakosha angle 0 = sin-(n2 / n1) ndiyo Iyo refractive index, N1 ndiyo refractive index yeGAN, nokudaro kuverenga iyo yakakosha angle 0. anenge 25.8 madhigirii. Muchiitiko ichi, chete chiitiko chekona 25.8 madhigirii mumativi matatu-dimensional kona yenzvimbo mukona-matatu-dimensional kona yenzvimbo inoshumwa. Parizvino, yekunze quantum kunyatsoshanda kweGAN chip ingangoita 30% -40%. Nokudaro, nekuda kwemukati wemukati we chip crystal absorption , Chikamu chekuvhenekera kune kunze kwekrisiti iduku zvikuru. Sekureva kwemishumo, iyo yekunze quantum kunyatsoshanda kweGAN chip parizvino yakatenderedza 30% -40%. Saizvozvo, mwenje unoburitswa ne chip unofanirwa kuendeswa kunzvimbo kuburikidza nemidziyo yekurongedza, uye mhedzisiro yechinhu pakuvhenekesa kwechiedza chechinhu chinofanira kutariswa. Naizvozvo, kuitira kuti uvandudze kushanda kwemwenje we AC-yemahara LED zvigadzirwa packaging, kukosha kweN2 kunofanirwa kuwedzerwa, kureva, iyo refractive index yezvinhu zvekurongedza kuvandudza kona yakakosha yechigadzirwa, nekudaro kuvandudza chigadzirwa chekurongedza mwenje. kunyatsoshanda. Panguva imwecheteyo, kutorwa kwezvinhu zvekuvhenekesa zvekutakura zvinhu kunofanirwa kunge kuri kudiki. Kuti uwedzere chiyero chechiedza kunze kwechiedza, chimiro chekuputira chakaiswa arched kana hemispherical. Nenzira iyi, kana mwenje uchipfurwa kubva pakurongedza kuenda kumhepo, inenge yakamira yakatwasuka kune iyo interface, saka hapana kuzere kuzere kunogadzirwa. 3. Pane zvinhu zviviri zvakakosha zve reflection treatment reflection treatment. Imwe ndiyo yekuratidzira kurapwa mukati meiyo chip, uye imwe iratidziro yemidziyo yekurongedza kune mwenje. Kuburikidza nekuratidzira kwemukati nekunze, ichawedzera chikamu che optical pass kubva mukati me chip, kuderedza Kutora kwemukati kwechiputi, kunatsiridza simba AC -isina LED yakapedza chigadzirwa chekuvhenekera. Panyaya yekurongedzerwa, magetsi-mhando maLED anowanzo kuunganidza simba -type chip pane simbi bracket kana substrate ine inopenya mhango. Iyo bracket -type reflex cavity inowanzo shandisa electroplating kuvandudza ratidziro. Nzira, kurapwa kwe electroplating kunoitwawo, asi nzira mbiri dziri pamusoro dzinokanganiswa nekururama kwe mold uye maitiro. Parizvino, iyo yemukati reflex mhango yepepa-mhando yemhando, nekuda kwekushayikwa kwekukwenenzverwa kwekukwenenzverwa kana oxidation yesimbi coating, iyo reflex mhedzisiro haina kunaka, izvo zvakonzera kuti mwenje wakawanda ubatwe mushure mekunge nzvimbo yekuratidzira yabviswa, uye haigoni kuratidzwa kune chiedza chechiedza pane chinotarisirwa chinotarisirwa, izvo zvinotungamirira pakusvika pakusvika kune chinangwa chinotarisirwa, izvo zvinotungamirira pakusvika pakusvika kune chinangwa chinotarisirwa, izvo zvinotungamirira pakusvika pakusvika pakusvika pakusvika kune chinangwa chinotarisirwa. izvo zvinoita kuti tisvike pakusvika pakusvika pazvinotarisirwa, izvo zvinoita kuti tisvike pakusvika pazvaitarisirwa, izvo zvinoita kuti tisvike pakusvika pazvaitarisirwa, izvo zvinoita kuti tisvike pakusvika pachinangwa. iyo inotarisirwa chinangwa, ichaita kuti isvike pakusvika pakusvika kusvika Kushanda kwemwenje mushure mekurongedza kwakaderera. Isu takagadzira reflex yekurapa maitiro neiyo organic material yakavharidzirwa nekodzero dzakazvimirira dzepfuma ine yakazvimirira pfuma yehungwaru mushure mekutsvagisa kwakawanda uye kuyedza. Chiedza chakapfurwa pamusoro pacho chinoratidza kunze kwechiedza. Kubudirira kwekugadzirisa kwechigadzirwa mushure mekugadzirisa kunogona kuwedzerwa ne30% -50% kana ichienzaniswa nekugadzirisa. Iyo mwenje mhedzisiro yeyazvino 1W chena mwenje magetsi LED inogona kusvika 40-50LM/W (yedzo mhinduro pane chinhambwe PMS-50 spectrum yekuongorora test chimbo), uye vakawana yakanaka yekurongedza mhedzisiro. 4. Panyaya yemagetsi machena AC -isina LED, kuvandudzwa kwesimba rechiedza AC kune hukamawo nekusarudzwa uye kugadzirwa kwehupfu hwefluorescent. Kuti uvandudze kushanda kwehupfu hwefluorescent kuti iite chipu chebhuruu, kutanga kwezvose, kusarudzwa kwehupfu hwefluorescent kunofanira kunge kwakakodzera, kusanganisira kukurudzira kurefu, kukura kwechidimbu, uye kubudirira kwekufuridzira. Chechipiri, kupfekedzwa kwehupfu hwefluorescent kunofanirwa kuvharwa zvakaenzana, uye ukobvu hwechipi chimwe nechimwe chinopenya chine chidimbu chinopenya chakakora zvakaenzana, kuitira kuti chisakonzerese kuti mwenje wepanzvimbo upfurwe nekuda kwekusaenzana ukobvu. Yakanaka kupisa disipation dhizaini inoita mhedzisiro yakakosha pakuvandudza simba-isina LED chigadzirwa mwenje kunyatsoita, uye zvakare ndicho chinodiwa kuti uve nechokwadi chehupenyu hwechigadzirwa uye kuvimbika. Uye yakanyatsogadzirwa mwenje chiteshi, pano kureva dhizaini yekugadzira, kusarudzwa kwezvinhu uye process process ye reflection cavity, kuzadza glue, zvichingodaro, izvo zvinogona zvinobudirira kuvandudza kugona kwemwenje wesimba -type LED. Kune simba-based white light LED, sarudzo uye dhizaini yekugadzira fluorescent poda yakakoshawo kuvandudza kuvandudzwa kwenzvimbo dzemwenje uye kuvandudzwa kwemwenje.
