Chii chinonzi chiedza emitting musimboti mwenje LED?

Chii chinonzi chiedza emitting musimboti mwenje LED? Mwenje we LED ndeye electroluminescent semiconductor material chip, iyo inorapwa pachibhuraketi nesirivheri guruu kana chena glue, uye yobva yabatanidzwa kune chip uye dhigirii bhodhi newaya dzesirivha kana dzegoridhe, uye yakavharwa ne epoxy resin yakaitenderedza kudzivirira iyo yemukati core waya. Basa, goko rinoiswa kwekupedzisira, saka kuvhunduka kwerambi re LED kwakanaka. 1. Chimiro chebhengi remwenje Chimwe chezvimiro zvinonyanya kukosha zvinoburitsa chiedza chemwenje ye LED (Light Emitting Diode) mwenje werambi bhinzi rakaenzana nebhinzi mukati merambi. Kunyangwe hukuru hwayo hudiki, basa rayo harisi diki.

Mushure mekuswededza mukati pane chimiro chemwenje we LED bead, isu tichawana wafer saizi yemhodzi yesame. Chimiro che chip chakanyanya kuomarara, uye chakakamurwa kuita zvidimbu zvakati wandei: yekumusoro Z layer inodaidzwa kuti P-mhando semiconductor layer, yepakati ndiyo ine chiedza-emitting layer, uye yezasi Z layer inonzi N-type semiconductor layer. Saka, mwenje we LED unoburitswa sei? 2. Nheyo yekubuda kwechiedza Kubva pakuona kwenyama: kana ikozvino inopfuura nepakati pechifukidziro, ma electrons muN-type semiconductor uye maburi ari muP-type semiconductor anodhumhana nechisimba uye anobatana zvakare mumucheka wechiedza-emitting kuti ibudise mafotoni, ayo anobudisa simba nenzira yephotons (ndiko kuti, chiedza chaunoona).

Led LED inonziwo light emitting diode, vhoriyamu yaro idiki uye haina kusimba zvakanyanya, haina nyore kushandisa zvakananga. Saka mugadziri akawedzera ganda rekudzivirira kwairi ndokuisa chisimbiso mukati, nokudaro achigadzira bhedhi remwenje re LED riri nyore kushandisa. Mushure mekubatanidza mabheji mazhinji emwenje e LED pamwechete, marambi akasiyana e LED anogona kuumbwa.

3. Mwenje ye LED yemarudzi akasiyana-siyana Semiconductors emhando dzakasiyana-siyana achabudisa mavara akasiyana-siyana echiedza, zvakadai sechiedza chitsvuku, chiedza chegirini, chiedza chebhuruu nezvimwe zvakadaro. Nekudaro, hapana semiconductor zvinhu zvinogona kuburitsa chena mwenje kusvika zvino. Asi mabhero emwenje e LED atinowanzo shandisa anogadzirwa sei? 4. Chizvarwa chemwenje machena e LED Pano tinoda kutaura nezvemubairo weNobel - Dr. Shuji Nakamura.

Akagadzira iyo yebhuruu LED, iyo yakaisawo imwe nheyo yechena LED. Zvichienderana nemupiro uyu unokosha, akapiwa mubayiro weNobel muFizikiki muna 2014. Nezvekuti ma LED ebhuruu anoshandurwa sei kuva ma LED machena, chikonzero chikuru ndechokuti kune imwezve ye phosphor mu chip.

Chirevo chinobudisa chiedza hachina kunyanya kushanduka: Pakati pezvikamu zviviri zve semiconductor, maerekitironi nemaburi zvinodhumhana uye zvinobatana kuti zvibudise mafotoni ebhuruu muchikamu chinobudisa chiedza. Chikamu chechiedza chebhuruu chakagadzirwa chichapfuura nepakati pe fluorescent coating uye kuburitswa zvakananga; chikamu chasara chicharova fluorescent coating uye kupindirana nacho kugadzira yellow photons. Chiedza chichena chinogadzirwa nekubatanidza (kusanganisa) mafotoni ebhuruu ane yellow photons.

Parizvino, huwandu hwemashandisirwo emwenje e LED hwakajairika. Tichitora Xinshengkai Optoelectronics semuenzaniso, machira emwenje e LED anogadzirwa nayo anoshandiswa zvakanyanya mukushongedza kwemukati nekunze, marongero emumugwagwa, zvishongedzo, magadheni, mota, madziva, zviratidzo zvekushambadzira, mahotera, zvitoro, KTV, nzvimbo dzekutandarira, nezvimwe.
