Heerkulka iyo dareenka cadaadiska cadaadiska ah ee loo yaqaan 'cummins' 3408627

Saamaynta piezoelectric

Marka dieletrics qaar ka mid ahi ay ka yaraanayaan awood u adeegsiga jiho gaar ah, eedeymaha ayaa laga soo saaray dusha sare, iyo marka xoogga dibedda laga saaro, waxay ku noqdaan dowlad aan kala go 'lahayn. Ifafaaledan waxaa loo yaqaan saameynta piezoelect-ka wanaagsan. Marka beero koronto lagu adeegsado jihada loo yaqaan 'foraal-ka' ee dieltcric, dielecticric-ka ayaa soosaarta isqarxin farsamo ama cadaadis farsamo jiho gaar ah. Marka garoonka korantada ee dibedda laga saaro, ciribtirka ama walbahaarka wuu dhammaan doonaa, kaas oo loo yaqaan waxyeelada Piezoelcric-ka ee Piezoelcric.

Element piezoelectric

Feejigaha Piezoelectricric waa dareeraha jireed iyo dareeraha jiilka awoodda. Qalabka 'piezoelectric' ee sida caadiga ah loo isticmaalo waa shid crystal (Sio2 _ 2) iyo isku-darka piezoeltics piezolectic.

The Piezoelectric-ka joogtada ah ee tusmooyinka piezoelectics waa dhowr jeer oo ah shid crystal, oo xasaasinimadeeda ayaa sareysa.

1. Saamaynta sawir-qaade

Marka iftiinka itagaadaa shay, waxaa loo qaddarin karaa inuu yahay xarig sawirro leh tamar tamar ah oo ah sheyga. Haddii tamarta sawirku weynaato, elektaroonigga ah ee ku jira walaxda ayaa ka takhalusi doonta caqabadaha xoogagga gudaha ah waxayna leeyihiin saameyn koronto ku habboon, oo loo yaqaan saameynta sawir-qaade.

1) Ficilka iftiinka, ifafaaleyaasha in elektrons ka baxsadka dusha sare ee shay waxaa loo yaqaan saameynta sawir-galka dibedda, sida tuubada sawir-galka ah iyo tubada sawir-dhexaadinta.

2) Ficilka iftiinka, ifafaale in dib u dhibka loo yaqaan 'isbedelka shay ee isbedelka gudaha waxaa loo yaqaan saameynta sawirka gudaha, sida sawir-qaade, photodiandeste, sawir-qaadid iyo sawir-qaadid.

3) Ficilka iftiinka, shay wuxuu soo saaraa xoog koronto jiho gaar ah, kaas oo loo yaqaan 'PhotovolTolecic', kaasoo loo yaqaan 'photovoletaic', oo loo yaqaan 'photovovoltaic', sida unugyada sawirka (aalad u xasaasi u tahay booska iftiinka shilka ee dusha sare ee sawirka).

2 iska caabbinta sawirka

Markuu sawir qaade uu ku jiro iftiinka, elektaroonigga ah ayaa u haajiraya soosaarka la-like-yada elektroonigga ah, kaas oo ka dhigaya iska caabinta inuu yaryahay. Iftiinka xoogga badan, hoos udhaca hoose. Iftiinka shilku wuu baaba'ay, lammaane elektroonigga ah ee elektiroonigga ah ayaa soo kabashada, iyo qiimaha iska caabbinta ayaa si tartiib tartiib ah ugu soo laabanaya qiimaheeda asalka ah.

3. Tuubada Sawirada

Tuunnada sawirrada (Photodiodiome, sawir-qaadaha, sawir-bixiyaha, sawir-qaadista, iwm.) Waxay ka tirsan tahay aaladda semiconductor.

4. Electroluminescence

Ifafaynta luminancescencence-ka waxaa soo saaray waxyaabo aan caadi ahayn oo lagu tuuro Elektaroonigga ayaa ah hanaanka si toos ah loogu beddelo tamarta korantada tamar fudud. Diode-diode-ka-laabashada (LED) waa aaladda kombuyuutarka semiconduattor Marka isgoyska PN-ka uu u gudbiyo si xushmad leh, tamar xad-dhaaf ah ayaa la soo saaray dib-u-kicinta elektaroonigga ah ee elektroonigga ah, kaas oo lagu sii daayo qaab sawir ah oo iftiimiya iftiinka.
