Ungasikhetha kanjani isibonisi se-LED endaweni ebanda kakhulu¼

Isikrini sokubonisa se-LED sangaphandle sisetshenziswe kabanzi ekwakheni izindonga, izikwele,izitolo ezinkulu, izikhungo zokuhamba nezinye izindawo, futhi isilethele izinto eziningi ezilula.

Lapho sikhetha isibonisi esiholayo, akufanele sicabangele kuphela ukubukeka kwayo, ukugcinwa kwayo, ibanga lokubuka nokukhanya, kodwa futhi sicabangele izimo zemvelo zendawo.

 

Kufanele siwukhethe kanjani umkhiqizo ofanele izimo ezibanda kakhulu?

 

Ngokungafani nezimo zokushisa eziphakeme, isikhumba sangaphandle sentambo yokubonisa ye-LED yangaphandle kulula ukonakala endaweni yokushisa ephansi isikhathi eside, okuholela ekujikelezeni okufushane ngisho nomlilo nezinye izinto ezimbi kakhulu; Kungase futhi kube nezinye izingxenye ze-elekthronikhi ezingakwazi ukusebenza kahle, ukuze sonke isikrini singakwazi ukusebenza kahle.

 

Ngakho-ke, izibonisi ze-LED zangaphandle kufanele zilawulwe ngokuqinile phezu kwekhwalithi yezinto zokusetshenziswa ukuze kuncishiswe ukulahlekelwa kwemikhiqizo okubangelwa izinga lokushisa eliphansi. Singaqala ngezici ezilandelayo:

 

1. Khetha izesekeli zokubonisa i-LED ezimelana nezinga lokushisa eliphansi

Izinto ziba brittle emazingeni okushisa aphansi, njengoba kwenza izibonisi ze-LED. Kusetshenziswa izinto zokusetshenziswa ezimelana nezinga lokushisa eliphansi namadivayisi, njengemaski ukumelana nokubanda nekhithi yegobolondo eliphansi, ukunikezwa kwamandla wezinga lokushisa eliphansi (kungaqala kokuthi -40â); Thatha i-anti-izinga lokushisa eliphansiikhabethe, izinto zikagesi ezilwa nezinga eliphansi nezixhumi. Ngakho-ke, ukuze sibhekane nemvelo ebandayo, singasebenzisa iKhabhinethi ye-aluminium ye-LED kanye nesikimu samandla aphansi okushisa.

2.Amandla okuvikela aphezulu kakhulu

Ngenxa yokuthi isibonisi se-LED sangaphandle sisebenza endaweni yangaphandle isikhathi eside, sinezidingo eziphezulu ku-PCB, ukunikezwa kwamandla kanye nephoyinti lokushisela elinokumelana nokushisa okuphezulu nokuphansi, ukumelana namanzi nokugqwala. Kunconywa ukuthi PCBS, izingxenye nezingxenye, okokushisela, njll. kufanele ziphathwe nge-conformation coating nokuvikelwa okubandayo, okufana nezinto zamakhemikhali (isb. uphethiloli, isipholile, njll.), ukudlidliza, umswakama, isifutho sikasawoti, umswakama nezimo eziphakeme neziphansi zokuvikela isifunda emonakalweni, ngaleyo ndlela andise impilo yabo yesevisi.
