Isici esibalulekile sokukhula okujwayelekile nokuphila kwezitshalo kuyakhaqabula, ngoba ukukhanya kubo kungenye imithombo yamandla. Futhi ngaphezu kokukhanya, izici ezifana ne-spectrum kanye nesikhathi sokukhanya kubalulekile ekukhuleni izithombo .
Izibani ze-LED zokugqamisa izithombo
Inzuzo yezibani ze- LED phambi kweminye imithombo yokukhanya yezithombo kuyabonakala:
- ukusetshenziswa kwama-LED kwenza kube lula ukuthola imishayo embukisweni obomvu nolubuluhlaza, okwenza kube ngcono ukukhula kwezithombo;
- ubude bamagagasi okukhanya ukuthi i-photosynthesis idinga ihluke ukusuka ku-longueur ye-wavel kusukela kwesibani esivamile sogesi, kuyilapho ama-LED ama-avelth ethwala ubude obufunayo;
- Ama-LED ahlinzeka ngombono omncane kakhulu, ngenxa yalokho ukusebenza kwawo kufinyelela ku-99.9%;
- ukusetshenziswa kukagesi uma usebenzisa izibani ze-LED kuphansi kakhulu, ngaphandle kwalokho, isidingo sokushintsha ama-light abanikazi bokushiswa sinyamalalala;
- Amanzi ahlasela kwi-LED awaholeli ekuhlulekeni kwawo;
- Kuzinhlelo ze-LED akekho ukupholisa;
- azifaki imisebe ye-ultraviolet ne-infrared, ebaluleke kakhulu kwezinye izitshalo.
Njengoba sibona, ukukhanya kwezimboni ezinezibani ze-LED, futhi ezenziwe ngezandla, akugcini nje ngokulondoloza imali, kodwa futhi kunomphumela omuhle kakhulu ezitshalweni.
Kubalulekile ukubala amandla afanele we-strip LED ukuze ukhanyise izithombo. Futhi ukuhlola ukuthi ngabe ukukhanya kwezimbande zakho kufike kanjani, yibuke nje - uma kubonakala kunempilweni enempilo, ngeziqu ezinamandla neziqabunga eziluhlaza - konke kuhambisane.
Iqiniso lokuthi izitshalo zithole ukukhanya okwanele uma zikhanyisa, zona zizothi: uma amaqabunga awo eqala ukuvala, ephethe isikhundla, sekuyisikhathi sokuvala izibani. Ubude besikhathi sokukhanyisa ngamahora angu-13, nakuba amanye amasiko azodinga wonke amahora angu-17.
Okulandelayo sizokutshela indlela yokwenza i-backlight ye-LED izithombo.
Izithombo ze-LED
Esiklasini sethu samakhosi sizobe silungiselela imodemu ye LED kusuka kuma-LED angashadile. Kamuva ingasetshenziswa njengesigqamile sezithombo.
Sizodinga ama-LED, angathengwa esitolo se-intanethi noma esitolo sokukhanyisa. Kulesi simo, banikwe amandla ama-watts angu-3 futhi bahlelwe ebhodini lezinkanyezi.
Sizofaka ama-LED kumaphrofayli ase-aluminium asetshenziswa ekwakhiweni kweminyango. Empeleni, ungasebenzisa amaphrofayili akhethekile wezibani ze-LED, kodwa zibiza kakhulu. Siyindlela efanele kakhulu ngomsebenzi wesango.
Ubukhulu bale phrofayela buyi-1 mm. Futhi ngenxa yokuqina kwayo kuyadingeka ukuba unamathisele kuwo amapulangwe enziwe nge-aluminium, ubukhulu bawo - 2 mm. Ungayenza nge-rivets. Futhi, ukuze uthuthukise ukuthuthwa kokufudumala, faka amapuleti unomngcele wamafutha ashisayo.

Hlangqa izimbobo kuphrofayli yokufaka ama-LED. Ngokuvamile, kunezinketho eziningana zokuhlanganisa ama-LED kuphrofayli: izikrini, ama-rivets kanye ne-hotmelt. Inketho eshibhile ukusebenzisa izibhamu.
Ukuze uqinisekise ukuthi i-rivet ayigcini othintana naye ebhodini, kubalulekile ukuyiqinisa ngokusebenzisa ukufaka ama-washer.
Ngenxa yalokho, ngemuva kokulungisa wonke ama-LED ngamakhwenyana, lokhu kuyimoduli. Amandla ayo ayoxhomeka kwinani lama-LED namandla abo.

Okulandelayo, faka ama-LED emaceleni futhi u-solder kumodemu wokushayela. Yikhethe ngokuhambisana namandla we-module etholakele kanye namanje we-LED.
Vula i-module ukuze uqinisekise impilo yenethiwekhi. Ngemuva kwalokhu, ihlala nje ukuyibeka phezu kwezithombo bese uqala ukuyisebenzisa njengoba iqondisiwe.
