Zviratidziro zve LED zvigadzirwa zvemagetsi.Chero bedzi vari zvigadzirwa zvemagetsi, ivo vanozokundikana zvachose panguva yekushandiswa.Saka ndeapi matipi ekugadzirisa maratidziro e LED?
Shamwari dzanga dzichisangana ne LED kuratidza dzinoziva kuti ma LED maratidziro akabatanidzwa pamwechete chidimbu nechidimbu che LED module.Sezvambotaurwa, zviratidziro zve LED zvigadziriso zvemagetsi, saka chimiro chayo chikuru inzvimbo yekuratidzira (rambi repamusoro), PCB (circuit board), uye control surface (IC component surface).
Kutaura nezve matipi ekugadzirisa maratidziro e LED, ngatitaurei nezve zvikanganiso zvakajairika kutanga.Zvikanganiso zvakajairika zvinosanganisira: chidimbu "mwenje yakafa", "makombi", chidimbu chisipo chemavara mabhuraki, chidimbu chitema masikirini, makuru matema masikirini, chidimbu garbled macode, zvichingodaro.
Saka maitiro ekugadzirisa aya akajairika glitches?Kutanga, gadzirira maturusi ekugadzirisa.Zvikamu zvishanu zvehupfumi zvemushandi wekugadzirisa wekuratidzira kwe LED: ma tweezers, pfuti yemhepo inopisa, simbi yekusimbisa, multimeter, kadhi rekuyedza.Zvimwe zvekubatsira zvinosanganisira: solder paste (tin waya), flux inosimudzira, waya yemhangura, guruu, nezvimwe.
1. Dambudziko re "chiedza chakafa".
Yenzvimbo "yakafa mwenje" inoreva chokwadi chekuti mwenje mumwe kana akati wandei pane mwenje wepamusoro weiyo LED kuratidza haina kupenya.Mhando iyi yekusajeka yakakamurwa kuva yakazara-nguva isina kupenya uye chikamu chekutadza kwemavara.Kazhinji, mamiriro ezvinhu aya ndeokuti mwenje pachayo ine dambudziko.Ingave yakanyorova kana iyo RGB chip yakakuvadzwa.Nzira yedu yekugadzirisa iri nyore kwazvo, ingoitsiva nefekitari-yakashongedzerwa mwenje we LED bead.Zvishandiso zvinoshandiswa ndeye ma tweezers uye hot air pfuti.Mushure mekutsiva iyo yakasara mwenje mabhedhi e LED, shandisa Edzai bvunzo kadhi zvakare, kana pasina dambudziko, yakagadziridzwa.
2. Dambudziko re "gonye".
"Caterpillar" ingori dimikira, izvo zvinoreva chiitiko chekuti bhara refu rakasviba uye rakajeka rinoonekwa pane chikamu chemwenje wepamusoro kana iyo LED inoratidzira yakabatidzwa uye pasina inopinza sosi, uye ruvara rwakanyanya rutsvuku.Mhedzisiro yechiitiko ichi ndeyekudonha kwemukati chip mwenje, kana pfupi pfupi yeIC pamusoro pechubhu mutsara kuseri kwerambi, yekutanga ndiyo yakawanda.Kazhinji, kana izvi zvikaitika, isu tinongoda kushandisa pfuti yemhepo inopisa kuvhuvhuta mweya unopisa pamwe chete ne "gonye" rinodonha.Kana ichivhuvhuta kune rambi rine dambudziko, rinowanzo OK, nekuti kupisa kunokonzeresa kuti iyo yemukati inodonha chip ibatane.Yakavhurwa, asi pachine njodzi dzakavanda.Isu tinongoda chete kutsvaga iyo inodonha mwenje wemwenje we LED, uye kutsiva iyi yakavanzika bhedhi remwenje zvinoenderana nenzira yataurwa pamusoro.Kana iri dunhu diki remutsetse chubhu kuseri kweIC, unofanirwa kushandisa multimeter kuyera yakakodzera IC pini yedunhu uye kuitsiva neIC itsva.
3. Zvikamu zvemavara zvidhinha zvisipo
Shamwari dzinoziva maratidziro e LED dzinofanirwa kunge dzakaona rudzi urwu rwedambudziko, kureva kuti, diki diki remavara akasiyana mabhuraki rinoonekwa kana iyo LED inoratidzira ichiridza zvakajairika, uye ine mativi.Dambudziko iri kazhinji nderekuti ruvara IC kuseri kwechivharo chemavara chinopiswa.Mhinduro ndeyekuitsiva neIC itsva.
4. chikamu nhema chidzitiro uye nzvimbo hombe dema sikirini
Kazhinji kutaura, dema skrini inoreva kuti kana iyo LED inoratidzira skrini ichitamba zvakajairika, imwe kana anopfuura ma module e LED anoratidza chiitiko chekuti nzvimbo yese haina kupenya, uye nzvimbo yeashoma LED module haina kupenya.Isu tinoidaidza kuti chidimbu chitema chidzitiro.Tinodaidza nzvimbo dzakawanda.Chidzitiro chitema chihombe.Kana ichi chiitiko chikaitika, isu tinowanzo funga nezve simba chinhu chekutanga.Kazhinji, tarisa kana iyo LED simba chiratidzo chiri kushanda zvakajairika.Kana iyo LED chiratidzo chemagetsi isiri kupenya, inyaya nekuti magetsi emagetsi akakuvadzwa.Ingoitsiva neitsva ine simba rinoenderana.Iwe unofanirwawo kutarisa kana tambo yemagetsi ye LED module inoenderana nedema skrini yakasununguka.Muzviitiko zvakawanda, kumonyazve tambo kunogonawo kugadzirisa dambudziko dema.
5. chidimbu chakasvibiswa
Dambudziko remakodhi akavharwa emunharaunda rakanyanya kuoma.Inoreva chiitiko chezvisina kurongeka, zvisina kujairika, uye pamwe zvinopenya zvidhinha zvemavara munzvimbo yenzvimbo kana LED inoratidzira skrini iri kutamba.Kana rudzi urwu rwedambudziko rukaitika, isu tinowanzo tanga tagadzirisa dambudziko rekubatanidza mutsara wechiratidzo, unogona kutarisa kana tambo yakatsetseka yakapiswa, kana tambo yetiweki yakasununguka, zvichingodaro.Muchiito chekugadzirisa, takaona kuti aluminium-magnesium waya tambo iri nyore kupisa kunze, nepo tambo yakachena yemhangura ine hupenyu hwakareba.Kana pasina dambudziko mukutarisa iyo yese yekubatanidza chiratidzo, wobva wachinjana ine dambudziko re LED module neyakatarisana yakajairika yekutamba module, iwe unogona kunyatso kutonga kana zvichigoneka kuti iyo LED module inoenderana nenzvimbo isina kujairika yekutamba yakakuvadzwa, uye chikonzero kukuvara kunonyanya kunetsa IC., Nzira yekuchengetedza ichave yakaoma zvikuru.Ini handisi kuzopinda mune zvakadzama pano.
