Guangmai Technology yog tus kws tshaj lij hauv kev uaXim xiav 1w smd coj 3030 2835 450nm 460nm.
Xiav lub teeb ci-emitting diodes, uas yog LEDs xiav, yog lub teeb-emitting diodes uas tuaj yeem tso tawm lub teeb xiav, thiab lawv cov kev tsim tawm hu ua&"; teeb pom kev zoo thib ob tom qab Edison." Kev tsim ntawm xiav LED tau ua rau tib neeg sib sau ua ke LEDs uas tuaj yeem tso tawm peb qhov xim thawj thiab siv LEDs los tsim kom muaj lub teeb dawb ci txaus. Lub tswv yim ntawm lub teeb LED dawb tau zoo heev txhim kho teeb pom kev zoo ntawm tib neeg.
Xyoo 2014, Xibfwb Yuki Akasaki ntawm Nagoya University thiab Meijo University hauv Nyij Pooj, Hiroshi Amano, Xibfwb ntawm Nagoya University, thiab Shuji Nakamura, xibfwb ntawm University of California, Asmeskas, tau koom ua ke Nobel Physics ntawm lub xyoo rau "tsim kom muaj kev ci ntsa iab. xiav lub teeb-emitting diodes, nqa lub zog-txuag ci ci dawb lub qhov chaw ”Kev kawm khoom plig.
Xyoo 1971, Jacques Pankove thiab Ed Miller tau qhia txog qhov ua tau los ua cov LED xiav nrog zinc (Zn) -doped gallium nitride (GaN) -txawm yog lawv tom qab ua thawj LED ua los ntawm gallium nitride tau ntsuab. Xyoo 1972, Tshuaj ntsuab Maruska thiab Wally Rhines ntawm Stanford University, nrog rau PhD cov tub ntxhais kawm ntawv hauv cov ntaub ntawv tshawb fawb thiab engineering hauv tsev kawm ntawv, tsim thawj hom uas tso lub teeb xiav-violet. LED. Cov khoom siv ntawm LED no yog gallium nitride doped nrog magnesium (Mg). . Xyoo 1974, Lub Tsev Haujlwm Saib Xyuas Kev Nyab Xeeb Hauv Tebchaws tau muab Maruska, Rhines thiab Stanford University tus xibfwb David Stevenson txoj cai patent rau cov txiaj ntsig saum toj no. Txog rau hnub no, magnesium (Mg) -doped gallium nitride tseem yog cov khoom siv yooj yim rau txhua qhov lag luam xiav LEDs thiab laser diodes. Txawm li cas los xij, xiav diodes ua los ntawm magnesium (Mg) -doped gallium nitride tso tawm lub teeb tsis muaj zog kom muab tso rau hauv kev siv tau. Ntxiv mus, kev tshawb fawb tom ntej ntawm cov khoom siv gallium nitride tsis muaj peev xwm ua tiav qhov kev kov yeej. Thaum Lub Yim Hli 1989, cov khoom siv hauv thawj qhov kev lag luam xiav LED tau tsim los ntawm Cree tsis yog gallium nitride, tab sis yog qhov tsis sib thooj band sib txawv semiconductor silicon carbide (SiC). Qhov ua tau zoo ntawm qhov xiav LED no tsawg heev, txawm tias tsis tuaj yeem ncav cuag 0.03%.
Thaum xyoo 1980s, hauv Tsev Kawm Qib Siab Nagoya hauv Nyij Pooj, Akasaki, uas twb muaj hnub nyoog tshaj tsib caug xyoo, tau coj nws tus tub kawm ntawv Hiroshi Amano rov pib tshawb fawb txog gallium nitride. Xyoo 1986, lawv ua tiav tsim cov gallium nitride siv lead ua uas yav tas los suav hais tias ua tsis tau. Xyoo 1989, lawv tau tshawb pom tias yog tias tam sim no dhau los ntawm cov siv lead ua, qhov kawg' lub luminescence tuaj yeem txhim kho. Tom qab ntawd, Shuji Nakamura, tus neeg ua haujlwm ntawm Nichia Tshuaj Kev Lag Luam, pom qhov kev tshawb fawb ntawm Isamu Akasaki. Ua raws li kev tshawb fawb qhia ntawm nws tus tswv thiab tus kws qhia ua haujlwm, thaum kawg nws tau tsim lub teeb ci ci ci LED thaum xyoo 1993. Hauv xyoo 2014, cov neeg tsim khoom ntawm xiav LEDs Shuji Nakamura, Hiroshi Amano, thiab Yuki Akasaki yeej qhov khoom plig Nobel hauv Physics xyoo ntawd.
Qhov tseem ceeb thiab kev tsis sib haum xeeb
Kev tsim ntawm xiav LED tso cai rau tib neeg siv LEDs los tsim kom muaj lub teeb dawb zoo. Qhov ua tau zoo ntawm cov hluav taws xob tso tawm LEDs siab dua li cov teeb roj teeb. Dawb LEDs tau pab txhawb rau kev tsim muaj ntau yam LED cov ntxaij vab tshaus, thiab tseem txhawb kev txhim kho teeb pom kev zoo. Tshwj xeeb, tom kawg ua rau tib neeg muaj peev xwm txo qis cov pa roj carbon thiab tawm tsam kev hloov pauv huab cua.
Txawm li cas los xij, qee tus neeg txhawj xeeb tias lub teeb xiav tawm los ntawm xiav LED tuaj yeem ua teeb meem rau tib neeg lub qhov muag. Vim tias lub teeb xiav tuaj yeem ua rau lub cev tsis zoo.
