Mazuva ano LED yava chinhu chisingawanikwe muhupenyu hwedu. Nhasi, ndichakupai sumo pfupi pamusoro pepfungwa, hunhu, uye kupatsanurwa kwayo.

Pfungwa ye LED

LED (Light Emitting Diode) chishandiso che semiconductor chakasimba chinoshandura magetsi zvakananga kuita Light. Mwoyo we LED i semiconductor chip, ine mugumo mumwe wakabatana ne scaffold, mugumo mumwe uri negative electrode, uye mumwe mugumo wakabatana ne positive end yemagetsi, kuitira kuti chip yese ivharwe mu epoxy resin.

Chip ye semiconductor inoumbwa nezvikamu zviviri, chimwe chacho chiri semiconductor yemhando ye p, umo maburi anotonga, uye chimwe chacho chiri semiconductor yemhando ye n, umo maerekitironi anotonga. Asi kana ma semiconductor maviri akabatana, "pn junction" inoumbwa pakati pawo. Kana magetsi akaiswa pachip kuburikidza newaya, maerekitironi anosundirwa kunzvimbo ye p, uko anosanganazve negomba uye anoburitsa simba muchimiro chema photon, ndiyo nzira iyo ma LED anopenya nayo. Uye kureba kwechiedza, ruvara rwechiedza, kunotsanangurwa nezvinhu zvinoumba PN junction.

Hunhu hwe LED

Hunhu hwe LED hunoratidza kuti ndiyo nzira yakanakisisa yekutsiva chiedza chekare, ine mashandisirwo akasiyana-siyana.

• Vhoriyamu Diki

LED idiki diki rakaputirwa mu epoxy resin, saka idiki kwazvo uye yakareruka.

-Kushandiswa Kwesimba Kwakaderera

Kushandiswa kwesimba re LED kwakaderera zvikuru, kazhinji, voltage yekushanda kwe LED ndeye 2-3.6V.
Iyo current inoshanda ndeye 0.02-0.03A.
Kureva kuti, haishandisi magetsi anopfuura 0.1W.

• Hupenyu Hurefu hweBasa

Nemagetsi nemagetsi akakodzera, ma LED anogona kushanda kusvika maawa 100,000.

• Kupenya Kwakanyanya uye Kupisa Kushoma

• Kudzivirirwa Kwezvakatipoteredza

Ma LED anogadzirwa nezvinhu zvisina chepfu, kusiyana nemwenje ye fluorescent, ine mercury uye inokonzera kusvibiswa. Anogona zvakare kudzokororwa.

• Yakasimba uye Inogara Nguva refu

Ma LED akafukidzwa zvizere ne epoxy resin, iyo yakasimba kupfuura mababu emwenje nemachubhu e fluorescent. Hakunawo zvikamu zvisina kusimba mukati merambi, izvo zvinoita kuti ma LED asaparare.

Kupatsanurwa kwe LED

1, Zvinoenderana nechubhu inoburitsa chiedzaruvaramapoinzi

Zvichienderana neruvara rwechiedza rwunoburitsa chiedza rwechubhu inoburitsa chiedza, inogona kukamurwa kuita tsvuku, orenji, girini (uye yero girini, girini yakajairwa negirini yakachena), bhuruu nezvimwewo.
Pamusoro pezvo, mamwe ma LED ane machipisi emavara maviri kana matatu.
Zvichienderana nechiedza chinoburitsa chiedza chakasanganiswa kana chisina kusanganiswa nevanoparadzira, vane ruvara kana vasina ruvara, mavara akasiyana-siyana e LED ari pamusoro apa anogonawo kukamurwa kuita mavara akajeka, asina ruvara akajeka, anoparadzira nemavara uye asina ruvara anowanzoparadzira emhando ina.
Madiodhi anoburitsa chiedza chakapararira uye madiodhi anoburitsa chiedza anogona kushandiswa semarambi ekuratidza chiedza.

2. Zvinoenderana nehunhu hwechiedzapamusoroyechubhu inoburitsa chiedza

Zvichienderana nehunhu hwepamusoro pechubhu inoburitsa chiedza, inogona kukamurwa kuita rambi rakatenderera, rambi resikweya, rambi re rectangular, chubhu inoburitsa chiedza chemeso, chubhu yedivi uye chubhu diki yekuisa pamusoro, nezvimwewo.
Rambi rakatenderera rakakamurwa kuita Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm uye Φ20mm, nezvimwewo.
Dzimwe nyika dzinowanzo nyora Φ3mm light-emitting diode seT-1, φ5mm seT-1 (3/4), uyeφ4.4mm seT-1 (1/4).

3. Zvinoenderana nechimiromadiode anoburitsa chiedza

Zvichienderana nechimiro che LED, kune ese epoxy encapsulation, metal base epoxy encapsulation, ceramic base epoxy encapsulation uye glass encapsulation.

4. Zvinoenderana nekupenya kwakasimba uye kushanda kwazvino

Zvichienderana nekupenya kwakasimba uye kushanda kwemagetsi, LED inokamurwa kuita kupenya kwakajairika (kupenya kwakasimba kwe100mCD);
Kupenya kwakasimba kuri pakati pe10 ne100mCD kunonzi high brightness light-emitting diode.
Mwero wekushanda kwemagetsi e LED unobva pagumi mA kusvika pamakumi e mA, nepo mwero wekushanda wemagetsi e LED ari pasi pe2mA (kupenya kwakafanana nekwe chubhu inoburitsa chiedza).
Kuwedzera kune nzira dzekuisa muzvikamu dzataurwa pamusoro apa, kunewo nzira dzekuisa muzvikamu nechinhu chakashandiswa uye nemabasa acho.

Ted: chinyorwa chinotevera chinotaurawo nezve LED. Chii ichocho? Ndapota rambai makateerera.
