Isixhumi si ... Kuyini isixhumi, futhi yiziphi izinhlobo zezixhumi?

Ukuze udale izicucu zokukhanya nezici, abadwebi basebenzisa izibani ezikhanyayo ezihlukahlukene ezivela kuma-LED. Ngezinye izikhathi kuyadingeka ukuhlobisa umthombo noma ukwakhiwa kwezinga eliphezulu ngezingxenye zokukhanya zamamitha amaningi. Ixhaswe ngamandla webhethri, amabhande anemibala yizimoto ezihanjisiwe.

Ifenisha yokukhanyisa noma ama-display cases, esikhathini eside esidlule bayeka ukusebenzisa izibani ze-neon. Amacwecwe e-LED asetshenziselwa ukukhanyisa ukuhlobisa indlu, emagcekeni, ezinyathelweni. Amateyipu afaka umswakama-flexible ane-Fused LEDs afakwe emachibini wokubhukuda nase-aquariums. Ukufakelwa okukhanyisiwe, amashebhu ezincwadi, izici zokuhlobisa endlini yokugezela zihlukanisa futhi zisekela ngaphakathi kwendawo.

Njengoba ubude be-tape ekhanyayo engxenyeni ye-reel buyingqayizivele ethile, ukudala imidwebo efanele, izixhumi ezilodwa zamakhamera ezisetshenziselwa ukulula - izixhumi zezingxube ze-LED. Ubude obucacisiwe buhlanganiswa ngokungeza noma ukusika ama-LED angaphezu kweqile ngosizo lwamadivayisi axhumene naye wokuqina.

Igama elithi "isixhumi"

Isixhumi sanamuhla yile divayisi ehlanganisiwe evala isiteshi sokukhanya kagesi ngokuyifaka nje. Ukuqonda lesi sihloko, kubalulekile ukukhumbula noma ukwazi umqondo onjalo njengamasektha kagesi. Kuyaziwa kusukela esikoleni se-physics sokuthi ukuxhumana kagesi kuhambisana nokufana. Ukuhlinzeka umthwalo ofanayo kuwo wonke ama-LED ku-tape nokuqeda ukushisa nokushisa okukhulu kwezakhi ezidlulele, amathrekhi axhunyiwe ngendlela efanayo. Yenza lokhu ngokusebenzisa izintambo ezihlukene, uhlanganise izicucu zamateyipu kumthombo kagesi.

Izindawo lapho ungenza khona ukuchotshozwa kuboniswa emgqeni ngokumaka. Ukukhanya kokukhanya kwe-LED kwe-strip kuncike ekutheni amandla angakanani nokuthi zingaki ama-diode athengiswa kumitha eyodwa ye-tape. Isamba se-diodes siningi lamathathu (60, 90, 120, njll). I-diode ngayinye ngayinye yenza uchungechunge lwezifunda zombane. Lokhu kubalulekile, ngoba imigoqo inikwe amandla yi-voltage ye-volts ayishumi nambili. Uma singayinaki le lwazi, khona-ke ama-diode ambalwa ekuqaleni nokuphela kwetheyipu ayohlala engasebenzi, okungukuthi, ngeke avule.

Yiziphi izixhumi ezenziwe

Ukuxhuma uhlelo lwe-tape kumanethiwekhi avamile we-120-volt, kusetshenziswa amandla kagesi. Izixhumi ezixhasayo ziyi-snap-in-in-like-like, inokwethenjelwa, intambo yokuhlanganisa yonke indawo evumelana nanoma yiluphi uhlobo lwetheyipu. Ukuxhuma ngosizo lensimbi kwisixhumi se-PSU, lo mxhumana naye usetshenziselwa ukuxhuma i-LED emgqonyeni kudivayisi yokukhulisa noma i-dimmer.

Isixhumi somxhumanisi siyisesekeli esikuvumela ukuthi uyenze ngaphandle kwezintambo ze-soldering ne-tin lapho ubeka isikrini emuva. Nakuba iziphazamisi ezithengiswayo zingekho i-oxidized futhi ngaphansi kwezimo ezithile zingahlala isikhathi eside, izinhlobonhlobo zezixhumanisi zilula isikhathi somhlangano futhi zisheshise yonke inqubo yokubeka i-backlight. Yingakho amadivaysi akhethekile adingekayo. Kungenzeka ukufaka ubude bomabhande obude obude noma ibanga eliphakathi kwabo (isibonelo, lapho ujikeleza noma emaceleni ezinsimbi zefenisha noma ezinye izakhiwo).

Abakhiqizi bakhiqiza izinhlobo zezixhumi ezibonakalayo zemibala eminingi (yezingu-4) nombala owodwa (enezinhlu ezimbili zamadiodini), ngo-8 mm no-10 mm ama-strips e-LED. Isixhumanisi sesiteshi esinesine yinkambo yokuhlanganisa okuxhumanisa ama-luminous bands kuma-amplifier noma isilawuli. Enye indlela yokubopha ndawonye imibala ye-LED - izixhumi ezinezintambo eziguquguqukayo. Ubude bawo obungama-20 cm buvumela ukuba wenze izibambo zento ukuguqula cishe noma yikuphi ukuma. Ngakho-ke, isixhumi singumshini jikelele, okuhlanganisa, ukuxhuma amateyipu kulayini olulodwa, kuqinisekisa ukusebenza kwalo.

Ukuqala ukufaka nokuhlangana

Ngaphambi kokugubha amateyipu ezindaweni ezihloselwe zona, kufanele "uqedele" konke ukuxhumana, xhuma isilawuli, i-dimmer ne-BP (i-AC rectifier). Khona-ke kubalulekile ukuhlola sonke isifunda sokusebenza. Kuphela emva kwalokhu, kungenzeka ukuqinisa imivimbo ye-LED ezindaweni ezibekelwe yona.

Umdwebo onemibala eminingi uxhunywe ngumlawuli. Ngaphezu kwalokho, izintambo zemibala ngayinye zinamathele ekufakweni okuhambelanayo. Ukuze wenze lokhu, izinhlamvu zembala zikhonjiswe ezincwadini zesiLatini (RGB noV). Bese uxhuma lolu xhumano olulungile ku-rectifier.

Indlela yokulungisa ukukhanya

Ukuze ulawule ukukhanya kwe-luminescence ne-multiticolor nama-monochrome bands, i-chain ye-strips ye-LED, i-dimmer kanye nokunikezwa kwamandla kwenziwa. Uma uxhuma noma yisiphi isakhiwo esimangalisayo sokwenza amandla ngezixhumanisi ezikhulayo, kubalulekile ukuba uqaphele. Uma kungenjalo, ngokuphazamiseka ngokuphazamisa nokunciphisa, ungahlela isigamu esifushane, lapho ama-bands aphuma khona.

Ukubalwa kwamandla we-PSU

Ukubala amandla okunikezwa kwamandla adingekayo, kufanele ukwandise ubude bebhande le-LED kanye nokusetshenziswa kwamandla okucacisiwe. Ngenani elifunyenwe, kufanelekile ukufaka cishe ngo-30% ukuqinisekisa ukuvimbela amaconsi amandla we-voltage enethiwekhi.
