Kugadzirisa Athearn Locomotive ku LED Lighting

01 ye 05

Kubvisa I Incandescent Mabhuru

Athearn inounza zvakasiyana-siyana zveH HO motokari nemashoko akajeka uye kushanda kunovimbika. Asi kunyunyuta kumwe chete pakati pevatungamiri ndeyekuti vanoramba vachishandisa 1.5-volt incandescent bulbs yezviedza zvavo.

Apo magetsi anopa mavara akanaka, anogona kupisa nokukurumidza. Nenzira yakanaka, idzi dzinowanikwa dzinogona kutendeukira kuzviedza zve LED. Ma LED anotora nguva yakareba kwenguva refu uye kuderedza kutsvaira kwemhepo-iyo inogona kuva yakakosha pane imwe nzvimbo ine zvakawanda zvezvikwereti.

Aya maitiro achashanda kune mamwe mavara ezvikepe. Kunyange zvazvo kuiswa kwega kwega kwega kunogona kusiyanisa zvishoma, matanho ekutanga achava akafanana. Muenzaniso wakaratidzwa mune uku kutendeuka ndewegadzirira yakagadzirira-kuenda-Run SD40. Nokuda kwekugadza uku, zvose LED uye fiber optics zvichashandiswa.

Nhanho yekutanga ndeyekubvisa mabhuru ekudzivirira. Iyo duku duku inobatanidzwa panzvimbo ne glue mukati mehombe. Iyi glue inogadzikana nemvura. Ingoisa donho remvura pane glue uye rega igare kweinenge kweminiti. Iwe unokwanisa kukwanisa kunyatsonyora pry maibhuru asina kusununguka pasina uye nechinetso.

Bvisai waya kubva paPBB board. Iwe unogona kushandisa mabheji akafanana pabhodhi yeZV LED idzva. Kana iwe uri kuisa DCC decoder , unogona kushandisa tabhi pabhodhi, kana kuti tambo yakaoma kune yakachena, bhuruu uye yeroya inotungamirira pane chirevo.

Pre-wiring the LEDs

Kusiyana nemafuta ekudzivirira, ma LED anotsvaga. Zuva roga rega rine maitiro akanaka uye akaipa.

Iyo yakanaka (+) inotumidzwa inonzi anode uye kana LED iri kutungamira ichave yakareba. Zvimwe zve LEDS, sepamusoro pekukwirira kwemavara, zvichave nenzvimbo yakateteka kana kuisa pane + kurutivi.

Chikamu (-) chakaipa (-) chinonzi cathode uye chichava chiduku chemashure maviri. Zvakakosha kutengesa LED zvakanaka.

Iwe uchatodawo kupikisa kuti uderedze kutora kunotumirwa ku LED. Iwe unogona kufambisa kupikisa kune rumwe rutivi.

Pamusana pemhando dzekufambisa zvidzidzo, kusanganiswa kwe LED uye kurwisana kunoratidzwa pano kuchashanda zvakanaka. Ma LED ari T1 3mm "zuva rakachena." (Kuti zviri nani kutevedzera mazamu emabhandi, tsvaga kuchena kwezuva kana kutonhorera LED yakachena) Vamwe vachave neine bluish hue.) Pair idzi ne 1k ohm 1/4 Watt resistors.

Icho chiri nyore kwazvo kutengesa LED yekona uye chiedza chekuchengetedza usati waisa mulocomotive. Iwe unogona kupfupisa zvakanyanya kutungamira kweVAT LED. Ingozvitsanangurira kuhupamhi hwaidiwa nevatambi vematare. Chikamu chinotangira mukati mezvikwereti zvakawanda, shandisa semutungamiri muduku zvingaita.

Ita kuti LED dzidzokere kumashure uye shandura anode pamwe chete. Zvadaro gadzirisa urefu hurefu hwetambo kuti ubatanidze kuPCB kana kuti kudimburira. Kana kuoma kwekasa kumudziri wepamusoro zvakananga, izvi zvinofanira kusungirirwa kune mutungamiri webhuruu.

Zvadaro, tambo inopikisa kune imwe neimwe ye cathodes.

Wiring the LEDs to the PCB

Zvadaro, ma LED anoda kushamwaridzana nelocomotive. Zvakare, iwe unogona kushandisa bhodhi rePBB muimba yekutora kana kuenda kune imwe DCC decoder. Zvakanakisisa kuronga mberi uye funga nezvenzira iyo iwe uchataurirana nayo fiber optics kune LED uye LED pane bhodhi kuitira kuti iwe unogona kugona kubvisa / kuvhara chivakoti.

Pamusoro pePCB, shandisai anode kusvika kune imwe nzvimbo uye ma-cathodes maviri kusvika kumusoro uye kushandura magetsi matsvene maererano.

Kana uri muchengeti, shandisa tambo chena yekona, tsvuku kune reverse chiedza cathode uye yebhuruu yezvikamu.

Shandisa chimwe chekupisa kupisa tubing pamusoro pematare usati wanyatsobatana. Zvadaro isa nzvimbo iyo yakagadzirwa pamusoro pematare asina kushandiswa uye ushandise pamucheto wesimbi yako yeeddering kuti uipedze pedyo nejoka. Shandisai tese yeumagetsi yepamusoro pamusoro peanode connection. Nzvimbo yakaoma mukati memazamu-haafaniri kutora chero mikana isina kubatana.

Kana iwe uri kuwedzera mamwe magetsi (magetsi ematope, magetsi anonyevera, magetsi emakati, etc.) zvinongodzokorora matanho aya uye shandisa zvinotungamirira zvakakodzera.

Kuwana Fiber Optics

Shandisa fiber optics kuti utakure chiedza kubva kuma LED kusvika kune lenzi. Kune vazhinji injini dzeAtarn, .040 makanda achashanda zvakanaka.

Apa ndipo apo kusungirwa kunowedzera zvishoma. Iwe uchafanirwa kurongeka mberi kuti uone nzira yakanakisisa yekuita pamusoro pekuiswa panzvimbo yako. Pamusana pekushandisa iyi, zvaive nyore kwazvo kuedza zvakakodzerwa nemidonzvo, kuisimudza mumagetsi, ezvo kuwirirana nekanda panzvimbo (kuchengetedza kushandiswa kwechigadziriswa) uye kugadzirisa fiber optics kusvika kure.

Iwe unogona kuwana zviri nyore mune dzimwe mhando yekubatanidza yose ye fiber optics kutanga, kuisa sangano re LED kumumuviri uye zvino kuita kuti kuwirirana kuPCB / decoder yekupedzisira.

Chokutanga, chengetedza fiber imwe neimwe yechipfuva kusvika kure kureba kubva kune lens kuenda kune LED. Siya zvishoma.

Bond kumigumo ye fiber optics pamwe chete nehuwandu hwekupisa-shrink tubing. Nezviedza zvepakati, shandisa duku shoma rekutakura kuti utange kubatana neveviri rinotungamira pamwechete nemigumo yayo kunyange. Zvadaro shandisa imwe yakakura kupenya tubing kuti ubatane neviri uye LED. Iyo tubing inofanirwa kufanana yakananga kumativi ose e LED. Dzivisa kushandisa kupisa kwakanyanya pamubhadharo kuti ude sezvo zvichigona kukuvadza fiber optics.

Iwe uchakwanisa kutora michina kubva pa LEDs uye udzokezve kana zvichidiwa apo iwe unosangana nemuenzaniso.

Dhinda fiber optic inopinza nyeredzi kuti kudzivirira chiedza kubva pakufambisa kuburikidza nevateveri, mafiriji emagetsi kana zvimwe zvizaruriro mumuviri.

Lenses

Nemiviri yakaungana uye zvose zvakabatana mukati, danho rekupedzisira ndedze kupedza magetsi pachavo.

Chengeta fiber optics kusvika kure. Tora nhete yesimbi yako ye-soldering pedyo nechokuguma kwemakumbo uye kuguma kunofanira kubuda kunze. Kana izvi zvichikupa zvakakwana zvekuonekwa kwema-lens, iwe wakanaka kuenda. Iwe unogona kushandisa zvakare mapurasitiki akajeka kubva kuDestern West mumasangano. Gadzira fiber optics kuitira kuti vagare mukati meimba uye glue mapurasitiki epamberi.

Shandisa chidimbu che tepi kuti ubatisise uye uise majekisi maduku panzvimbo.

Mushure mokunge maita zvishoma zvekushandurwa uku, muchawana nzira yacho inokurumidza kukurumidza. Kutenga nehuwandu, mari yezvinhu zvakakosha pasi pe $ 2 nemari yekutengesa - pamusoro pezvaunoshandisa pakugadzirisa mabhodha nguva imwe neimwe.
