1.3 Liphanele tsa Poster ea LED

Lisebelisoa tsa khabinete ea pontšo ea LED haholo-holo li na le tšepe, motsoako oa aluminium, alloy ea magnesium, le aluminium ea die-cast. Lisebelisoa tse fapaneng ha li khetholle feela boima ba pontšo empa hape li ama ka ho toba litšenyehelo.

Boima ba likhabinete tsa poster ea dijithale tsa LED bo fapana haholo ho latela thepa. Likhabinete tsa tšepe hangata li boima, li boima ba lik'hilograma tse 25-35 ka mithara e le 'ngoe, li loketse liketsahalo tse hlokang matla a phahameng; aluminium alloy cabinets e bobebe, e boima ba lik'hilograma tse 15-20 ka square meter, e sebelisoa haholo mererong e mengata; lik'habote tsa magnesium alloy ke tse bobebe ka ho fetisisa, tse boima ba lik'hilograma tse 10-15 ka mithara e le 'ngoe, tse loketseng lisebelisoa tse phahameng tse hlokang ho fokotsa boima ba 'mele; die-cast aluminium likhabote li pakeng tsa, boima ba lik'hilograma tse 20-30 ka square meter, fana ka matla a matle le botsitso. Ho khetha thepa e nepahetseng ho hloka hore ho nahanoe ka botlalo litlhoko tsa morero le tekanyetso.

1.4 PCB Board

Litsenyehelo tsa mapolanka a PCB haholo-holo li tsoa ho mofuta oa lisebelisoa tse tala le palo ea likarolo.

Lisebelisoa tse tloaelehileng tsa boto ea PCB li kenyelletsa mapolanka a potoloho ea FR-4 le li-laminate tsa koporo (CCL), tse nang le CCL ka kakaretso e fetang liboto tsa potoloho tsa FR-4 fiberglass. Liboto tsa potoloho tsa fiberglass tsa FR-4 li atile haholo ebile ha li theko e tlase, athe CCL e sebetsa hantle ho tšoarella le phetiso ea matšoao.

Ho feta moo, palo ea likarolo ho li-module tsa ponts'o ea LED e amana hantle le theko. Ha li-layers tse ngata li na le mojule, sekhahla sa ho hloleha se tlase, 'me ts'ebetso ea tlhahiso e rarahane le ho feta. Le hoja liqapi tse nang le mefuta e mengata li eketsa litšenyehelo tsa tlhahiso, li ntlafatsa haholo botsitso le ho tšepahala ha lipontšo tsa LED, haholo-holo tsa bohlokoa ka lipontšo tsa LED tse boholo bo boholo le tse phahameng. Ka hona, ha u khetha li-module tsa pontšo ea LED, khetho ea lihlopha le lisebelisoa li tla ama ka ho toba litšenyehelo, botšepehi le ts'ebetso ea li-poster tsa LED.

1.5 Phepelo ea Matla a LED

Motlakase oa LED, e le karolo ea bohlokoa ea li-poster tsa LED, o na le phello e ke keng ea latoloa litšenyehelong. Lisebelisoa tsa motlakase tsa boleng bo phahameng ba LED li na le matla a nepahetseng a motlakase le a hona joale a ho hlahisa, ho netefatsa hore ho sebetsa ka mokhoa o tsitsitseng ha li-diode tsa LED, ho fokotsa likotsi tsa tšenyo, kahoo ho lelefatsa bophelo ba tšebeletso, e leng se etsang hore e be theko e boima haholo. Ho sa le joalo, matla a matla a phepelo ea motlakase a tlameha ho ts'oana le lintlha le boemo ba ts'ebeliso ea poster ea LED. Lisebelisoa tsa matla a phahameng le tse sebetsang hantle li batla li le tura. Ka mohlala, li-poster tsa LED tse ka ntle li hloka matla a matla a matla a sa keneleng metsi ho ikamahanya le maemo a rarahaneng le ts'ebetso e boima haholo, e leng se eketsang litšenyehelo tse akaretsang tsa li-poster tsa LED ha li bapisoa le lisebelisoa tse tloaelehileng tsa motlakase bakeng sa li-poster tse nyenyane tsa LED. Pontšo ea poster ea LED e boholo ba 640192045mm ka kakaretso e na le tšebeliso e phahameng ea matla e ka bang 900w ka mithara ea lisekoere le tšebeliso ea matla e ka bang 350w ka mithara e 'ngoe.
