Indlela yokwenza laser ku-DVD?

Mhlawumbe wonke umntwana ukuze ufunde mayelana khona laser, Waphupha eyabo, uyakwazi ukusika konke endleleni yayo: ngokjuni, ngamathse nensimbi. Yiqiniso, leliphupho ayikwazanga waqaphela, ngoba lasers ephezulu amandla ayingozi kakhulu bavunyelwe ezandleni kumphakathi wonkana. Okwamanje, nokho, lapho ukuthuthukiswa ubuchwepheshe bama-computer, noma ubani angaba ukufeza leliphupho okungenani ngokwezinga elithile.

I laser DVD - idivayisi liyatholakala kubo bonke abanale engadingeki (kodwa sisasebenza) drive. Yiqiniso, wathola "izikhali" ngeke bakwati kulimata izinto kanzima, kodwa iphepha, amakhadibhodi plastic ngisho yena impela onekhono.

Ukuze wenze laser ku-DVD ngezandla zakhe, kubalulekile kakhulu ukukhithika: egijima (sikaphalafini edingekayo) drive voltage capacitors, izintambo, mobile Ibhethri yefoni, multimeter, a Resistor, insimbi nokunamathisela ngomthofu, pointer, flashlight LED. Futhi-ke, isifiso, isikhathi khulula namakhono nokunamathisela ngomthofu.

Ukuze wenze laser ku-DVD-drive, kubalulekile ukuqaqa ke. Kumele wakhumbula ukuthi ukuze ukuklama ofanele kuphela ngokubhala drive, ukuze abanye abanayo amandla anele.

Ukuqaqa idrayivu, udinga ukuthola kuwo diode laser. Kumele kukhunjulwe ukuthi iyiphi drive bobabili: Obuthakathaka (IR diode), omunye anamandla (laser-obomvu). Ukuhlukanisa phakathi kwabo kunzima, kodwa kungenzeka: i-diode qinile okuyinto edingekayo ukuze umkhiqizo laser ungaphakathi idrayivu ukuthutha futhi kurediyetha emikhulu.

Phawula ukuthi ngaphambi kokukhipha diode laser Kunconywa ukugqoka esihlakaleni wayibhinca, ngoba (diode) kakhulu lokhu 'kwesaba' ka zikagesi ezingasetshenziswa kubuqede. Kuleso simo, uma isongo akuyona futhi akunakwenzeka ukuba uthole, udinga ukugoqa a mncane wire laser iziphetho.

Ngemva diode umshayeli kudingeka solder ukususwa. Ngaphandle kwayo, le laser DVD ngeke bakwazi ukuthola ukudla, kudingeka usebenzele ukuba uhambe. Ukuze abashayeli zidinga ezimbili voltages we capacitor 100 0.1 microfarad kanye Resistor, amandla lamanje zazo kuyakhethwa ngokuya ngesivinini drive (250, 300, 400, 450 kanye 500 ma, ngokulandelana, ngoba 16x, 18x, 20x, 22x futhi 24x).

Lapho nokunamathisela ngomthofu lezi zinto futhi okukhipha izintambo kuya plus futhi lokususa kubaluleke kakhulu hhayi ukutjhugulula polarity, kungenjalo laser ngeke ukuwohloka ngokushesha.

Ukuze amandla idivayisi angasebenzisa ibhethri ye umthamo iselula 200 kuya ku-300 ma. Nokho, kungase kudingeke futhi obunamandla kwabanye lasers.

Futhi njengoba umthombo wamandla ingasetshenziswa AA amabhethri.

Ukuze uhlole ukuthi umshayeli soldered kahle, udinga ixhume wesibili (ababuthakathaka) diode idrayivu, futhi nge multimeter ukukala amandla kwe-current.

Uma kwenziwe ngendlela efanele, ungakwazi ekugcineni ukuqoqa laser ku-DVD, usifake izindlu oyifunayo. Ukuze idivayisi isikhathi eside, kutuswa ukuba silungise zonke izakhi endaweni nge glue unamathelise kubo.

Ingabe laser DVD ilula ngokwanele, kodwa uma usebenza naye ukuba aqaphele. Kumele kukhunjulwe ukuthi kungabangela umonakalo, ngakho-ke asikwazi ziqondiswe lesilwane noma lomuntu. Eye laser kungaholela ukuwohloka ngisho nokulahlekelwa umbono.
