LED inogadzira sei chiedza?

Electroluminescence ndiyo nzira iyo ma LED (Chiedza Emitting Diodes) anogadzira chiedza. Aya ndiwo mashandiro azvinoita:

1-Semiconductor Material: A semiconductor zvinhu, kazhinji musanganiswa wezvinhu zvakaita se phosphorous, arsenic, kana gallium, inoshandiswa kugadzira LED. Zvose n-type (negative) nzvimbo, iyo ine maerekitironi akawandisa, uye p-type (positive) nharaunda, iyo ine kushaya maerekitironi (maburi), inogadzirwa apo semiconductor inoputirwa netsvina.

2-Erekitironi-Gomba Recombination: Maerekitironi anobva kunzvimbo ye-n-rudzi anomanikidzwa akananga kunharaunda yep-mhando kana magetsi akaiswa mhiri kwe LED. Maerekitironi aya anosanganazve nemakomba munzvimbo yep-mhando.

3-Photon Emission: Simba rinoburitswa sechiedza (mafotoni) panguva iyi yekubatanidzazve. Iyo simba bandgap ye semiconductor zvinhu zvakashandiswa inosarudza hue yechiedza chinoburitswa. Chiedza chinouya nemavara akasiyana-siyana zvichienderana nezvinhu.

4-Kubudirira: Sezvo huwandu hwesimba mu LED hunoshandurwa kuva chiedza pane kupisa-dambudziko rinowanzoitika nemagetsi emagetsi emagetsi-ma LED anoshamisa zvikuru.

5-Encapsulation: Nekuisa iyo LED mune yakajeka resin kana lens, mwenje wainoburitsa unogara uchivandudzwa. Izvi zvinogona zvakare kubatsira kuparadzira mwenje uye kuita kuti itaridzike zviri nani.

Mukuenzanisa nenzira dzemazuva ose ekuvhenekesa, nzira iyi inoita kuti ma LED ape chiedza chakanyanya, chakanyanyisa asi achishandisa simba shoma shoma.

Pasinei nehupenyu hwavo hukuru uye kushanda zvakanaka, mwenje we LED unogona kuva nehuwandu hwezvinhu zvakajairika, zvakadai se:
1) Rudzi rweKupisa Kusiyanisa: Kuvheneka kusingaenzaniswi munzvimbo kunogona kuguma nekushanduka kwekushisa kwemavara pakati pemabhechi emwenje e LED.

2) Flickering: Kana ichishandiswa neasingaenderane dimmer switch kana paine matambudziko nemagetsi, mamwe magetsi e LED anogona kupenya.

3) Kupisa zvakanyanya: ma LED anogadzira kupisa kushoma pane mwenje wenguva dzose, asi kusakwana kwekupisa kupisa kunogona kukonzera kupisa, izvo zvinogona kuderedza hupenyu hwema bulbs.

4) Matambudziko Mutyairi: Kuti udzore simba, mwenje we LED unoda vatyairi. Chiedza chinogona kupenya, kudzima, kana kumira kushanda zvachose kana mutyairi akatadza kushanda zvakanaka kana kuti ari wemhando yakaderera.

5) Dimming Compatibility: Matambudziko ekuita anogona kumuka nekuti mamwe magetsi e LED haaenderane neazvino dimmer switch.

6) Limited Beam Angle: Kuvhenekera kusina kuenzana kunogona kuguma kubva kumagetsi e LED ane zvishoma zvishoma, izvo zvingave zvisina kukodzera kune zvakawanda zvinoshandiswa.

7) Mutengo Wokutanga: Kunyange zvazvo magetsi e LED achichengetedza mari nekufamba kwenguva, anogona kudhura zvakawanda kutenga pakutanga kupfuura magirobhu akajairwa.

8) Kunetsekana Kwezvakatipoteredza: Kana isina kuraswa nenzira kwayo, tsvaga mazinga ezvinhu zvine njodzi semutobvu kana arsenic inowanikwa mune mamwe marambi e LED anogona kukanganisa nharaunda.

9)Kusiyana-siyana muHunhu: Kune zvakawanda zvakasiyana-siyana zve LED zvinhu pamusika, uye hazvisi zvose zvinogadzirwa kune zvakafanana zviyero, izvo zvinokonzera kusiyana kwehupenyu hurefu nekushanda.

10)Kusapindirana neZvimwe Zvigadziriso: Mamwe magirobhu e LED, kunyanya ayo akagadzirirwa akajairwa incandescent bulbs, haakwanise kushanda zvakanaka mune chaiwo magadzirirwo.

Kusarudza zvinhu zvemhando yepamusoro, kuve nechokwadi kuti zvinoshanda neazvino masisitimu, uye zvinoenderana nemirairo yekuisa inowanzodikanwa kugadzirisa matambudziko aya.

Kune akawanda mwenje mitsetse yekusarudza kubva pamusika izvozvi, sengeCOB stripCSP tambo, yakasiyana neiyoNhoroondo ye SMD, taura nesu kana uchida masampuli ebvunzo.
