Mazuva ano LED yave chikamu chisingawanikwe chehupenyu hwedu. Nhasi, ini ndichakupa iyo pfupi sumo yepfungwa, maitiro, uye kuiswa.

Pfungwa ye lED

A LED (mwenje unobvisa diode) is a solid-state-state semiconductor mudziyo unoshandura magetsi zvakananga kuchiedza. Mwoyo weiyo Semiconductor chip, nemugumo mumwe wakasungirirwa kune imwe neimwe yemagetsi isina kunaka, uye imwe yekupedzisira yakabatana nemugumo wemagetsi, kuitira kuti zvese zviputi zvakavharirwa mune epoxy resin.

Semiconductor chip inoumbwa nezvikamu zviviri, imwe yeiyo P-TYPE SEMICONONDURIT, mune iyo mahwanda anotonga, uye imwe yeiyo N-Type Semiconductor, pane ma elekroni anotonga. Asi apo maviri emeneondikoro akabatana, "pn junction" mafomu pakati pavo. Kana yazvino ichishandiswa kune iyo a aya, maelekitori anodzikiswa kuP-dunhu, kwavanobatirana negomba uye vanoisa simba muchimiro chemikicha, ndezvekuti ma leds anopenya sei. Uye wavelength yechiedza, ruvara rwechiedza, rwakatsemurwa nezvinhu zvinoumba iyo PN Junction.

Hunhu hwe lED

Hunhu hwezvisimudziro zvechitengo cherechedza kuti ndiyo yakanyanya kunaka mwenje tsime kutsiva tsika yechinyakare, ine huwandu hwakawanda hwekushandisa.

• Vhoriyamu diki

Iyo LED ndeyechokwadi chidiki chidiki chip chakazara mune epoxy resin, saka idiki kwazvo uye yakanyanya kujeka.

-Washuwa masimba masimba

Kuwedzerwa kwesimba kwesimba kwakanyanyisa kuderera, kazhinji kutaura, LED outlating voltage ndeye 2-3.6v.
Iko kushanda kwazvino ndeye 0.02-0.03a.
Ndiko kuti, hazvizvipindire kwete 0.1W wemagetsi.

• Hupenyu Hwese Webasa

Nezvazvino uye voltage yazvino, maLD anogona kuve nehupenyu hwebasa kusvika maawa zviuru zana.

• Kupenya kwakanyanya uye kupisa kwakaderera

• Kudzivirirwa kwezvakatipoteredza

MaLDS anogadzirwa nezvinhu zvisina chepfu, kusiyana nemwenje yezviuru zvemhando, iyo ine mercury uye inokonzeresa kusvibiswa. Vanogona zvakare kugadziriswazve.

• Yakasimba uye yakasimba

MaLD akazara mu epoxy resin, iyo yakasimba kupfuura zvese zvakajeka bulbs uye fluorescent tubes.Hazvinhu zvakare pasina zvikamu mukati memwenje, iyo inoita kuti ma leds isingadzoreki.

Kugadziriswa kweTer

1, zvichienderana nechiedza chinobuda chubhuruvaramapoinzi

Maererano nemwenje unoburitsa ruvara rwechiedza chinoburitsa tube, inogona kukamurwa kuita tsvuku, orenji, girini (uye yegirini yakasvibira uye yakachena girini), bhuruu uye zvichingoitika.
Uye zvakare, mamwe maLED ane machipisi evaviri kana matatu mavara.
Maererano nemwenje unoburitsa Diode yakasanganiswa kana kusasanganiswa nevanoparadzira, mavara asina ruvara, mavara ezvekutara anowoneka, mavara anopararira uye asina mavara ekupararira kwemhando ina.
Kupaza chiedza-cheodes uye chiedza - kutumira diode kunogona kushandiswa semarambi ekuratidzira.

2.ccording kune hunhu hwechinguvanapamusoroyeiyo mwenje inobuda tube

Zvinoenderana nehunhu hwechiedza chinoburitsa pamusoro pechiedza chinoburitsa tube, chinogona kukonzeresa mwenje, mrabalar lem.
Mwenje unotenderera wakakamurwa kuita φ2mm, φ4.4m, φ5mm, φ8mm, φ10m uye φ10m uye φ10mm uye φ10mm, etc.
Kune dzimwe nyika kunowanzo nyora iyo φ3ml Chiedza-Kubvisa diode seT-1, φ5ms seT-1 (3/4), uyeφ4.4mm seT-1 (1/4).

3.ccording kunechimiroyechiedza-cheki diode

Maererano nechimiro cheZvitengo, pane ese epoxy encaping, meth late epoxy encapsation, ceramic base ipoxy encapsiulation uye girazi encaping.

4.Ccording kuendaluminous kuwedzera uye kushanda zvazvino

Zvinoenderana nehuwandu hwekuvhenekera uye kushanda zvazvino zvakakamurwa kuita zvakajairika kupenya
Iyo inovhenekera huwandu pakati pegumi kusvika 100mcd inonzi yakanyanya kupenya mwenje-inoburitsa diode.
Iko kushanda kwazvino kweiyo General LED ndeye kubva kugumi ma kusvika pamakumi mana ezvekupedzisira kweiyo yakaderera mari yeregezi iri pazasi 2ma
Pamusoro penzira dziri pamusoro apa, kune zvakare nzira dzekuenzanisa neChip zvinyorwa uye nebasa.

Ted: Chinyorwa chinotevera zvakare nezve LED. Chii ichochi? Ndapota garai tuned.
