Mazuva ano LED yave chikamu chisingasvikiki chehupenyu hwedu.Nhasi, ini ndichakupa sumo pfupi kune iyo pfungwa, maitiro, uye kupatsanura.

Pfungwa ye LED

An LED (Light Emitting Diode) isimba-state semiconductor mudziyo unoshandura magetsi akananga kuChiedza.Mwoyo we LED i semiconductor chip, ine mugumo wakasungirirwa kune scaffold, imwe mugumo wayo ine negative electrode, uye imwe mugumo yakabatana kune yakanaka kuguma kwemagetsi, kuitira kuti chip yose yakavharirwa mumagetsi. epoxy resin.

Semiconductor chip inoumbwa nezvikamu zviviri, imwe yacho ip-type semiconductor, umo maburi anotonga, uye imwe yacho in-type semiconductor, iyo maerekitironi anotonga.Asi kana maviri semiconductors akabatana, "pn junction" inoumba pakati pavo.Kana ikozvino inoshandiswa kune chip kuburikidza newaya, maerekitironi anosundirwa kune p-region, kwaanosanganazve negomba uye anobudisa simba muchimiro chephotons, iyo ndiyo nzira iyo ma LED anopenya.Uye kureba kwechiedza, ruvara rwechiedza, kunotarwa nezvinhu zvinoumba PN junction.

Maitiro e LED

Iwo emukati maitiro e LED anoona kuti ndiyo yakanyanya kunaka sosi yekutsiva yechinyakare mwenje sosi, ine huwandu hwakasiyana hwekushandisa.

• Diki Volume

Iyo LED inongova diki chip yakavharirwa mune epoxy resin, saka idiki kwazvo uye yakareruka.

-Kushandisa Simba rakaderera

Simba rekushandisa re LED rakadzika kwazvo, kazhinji kutaura, LED inoshanda voltage ndeye 2-3.6V.
Iko kushanda ikozvino 0.02-0.03A.
Kureva kuti, haidyi inopfuura 0.1W yemagetsi.

• Hupenyu Hurefu Hwebasa

Nechaikozvino uye voltage, maLED anogona kuve nehupenyu hwesevhisi hunosvika 100,000 maawa.

• Kupenya kwakakwirira uye Kupisa kwakaderera

• Kuchengetedzwa Kwezvakatipoteredza

Ma LED anogadzirwa nezvinhu zvisina chepfu, kusiyana nemwenje yefluorescent, ine mercury uye inokonzera kusvibiswa.Anogona zvakare kushandiswa zvakare.

• Yakasimba uye Yakasimba

Ma LED akanyatsoputirwa mu epoxy resin, iyo yakasimba kudarika zvose ma bulbs emwenje uye fluorescent tubes.Iko hakunawo zvikamu zvakasununguka mukati memwenje, izvo zvinoita kuti ma LED arege kuparadzwa.

Iyo Classification ye LED

1, Zvinoenderana nechiedza emitting chubhucolorpoints

Zvinoenderana nechiedza chinoburitsa ruvara rwechubhu inoburitsa mwenje, inogona kukamurwa kuita tsvuku, orenji, yegirini (uye yero yegirini, yakajairwa yegirini uye yakachena girini), bhuruu zvichingodaro.
Mukuwedzera, mamwe ma LED ane machipisi maviri kana matatu mavara.
Zvinoenderana nechiedza chinoburitsa diode yakasanganiswa kana isina kusanganiswa nema scatterer, ane mavara kana asina ruvara, ari pamusoro akasiyana mavara e LED anogona zvakare kukamurwa kuva mavara akajeka, asina ruvara akajeka, ane mavara akapararira uye asina mavara emhando ina.
Kuparadzira chiedza-emitting diodes uye chiedza - emit diodes inogona kushandiswa semwenje wechiratidzo.

2.Maererano nemaitiro ezvinopenyapamusoroyechubhu inobudisa chiedza

Zvinoenderana nehunhu hwechiedza chinoburitsa pamusoro pechiedza emitting chubhu, inogona kupatsanurwa kuita rambi rakatenderera, mwenje mativi, rectangular rambi, kumeso mwenje emitting chubhu, padivi chubhu uye micro chubhu yekumisikidza pamusoro, nezvimwe.
Mwenje wedenderedzwa wakakamurwa kuva Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm uye Φ20mm, nezvimwewo.
Kune dzimwe nyika kazhinji kunorekodha Φ3mm chiedza-emitting diode seT-1, φ5mm seT-1 (3/4), uyeφ4.4mm seT-1 (1/4).

3.According to thechimiroyemwenje-emitting diodes

Zvinoenderana nechimiro che LED, kune ese epoxy encapsulation, simbi base epoxy encapsulation, ceramic base epoxy encapsulation uye girazi encapsulation.

4.According tokupenya kwesimba uye kushanda ikozvino

Zvinoenderana neyakajeka kusimba uye kushanda ikozvino yakakamurwa kuva yakajairika kupenya LED (ruminous intensity 100mCD);
Kupenya kwakanyanya pakati pe10 ne100mCD kunonzi kupenya kwepamusoro mwenje-emitting diode.
Iko kushanda kweiyo general LED kunobva kugumi mA kusvika kune gumi nemaviri mA, nepo kushanda ikozvino kweyakaderera ikozvino LED iri pazasi 2mA (kupenya kwakafanana nekweyakajairika light-emitting chubhu).
Pamusoro peiyo nzira dzekuisa pamusoro apa, kune zvakare nzira dzekurongedza ne chip zvinhu uye nebasa.

Ted: chinyorwa chinotevera chiri zvakare nezve LED.Chii ichochi?Ndapota ramba wakatarisa.
