Waba uzi kubara ikoreshwa rya LED Yerekana?
Itangazamakuru ryamamaza hanze ryahindutse itangazamakuru ryukuri, kandi agaciro karyo hamwe na videwo yumucyo mwinshi kandi ushimishije ntisimburwa.
Abantu benshi bahangayikishijwe nimbaraga zo kwerekana LED hanze?Cyangwa ni gute imbaraga zo kwerekana hanze ya LED zibarwa?
Uyu munsiYONWAYTECHazatanga intangiriro muri make kuriyi ngingo.
Hamwe niterambere ryikoranabuhanga, itangazamakuru ryamamaza hanze rihora ritera imbere.
Nyuma yuko abumva amaradiyo, televiziyo, ibinyamakuru, nibinyamakuru bikomeje gutandukana, kwamamaza hanze byayoboye ibitangazamakuru byerekana byahindutse itangazamakuru ryukuri rifite agaciro kadasanzwe ntagisimburwa.
Ubwa mbere, kubyerekeranye nubunini bwimbaraga zo hanze ziyobowe na ecran:
Hariho ubwoko bubiri bwa LED yerekana imbaraga: impinga nimpuzandengo.
Imbaraga zitwa peak power ahanini zerekeza kuri voltage ako kanya nigiciro cyubu mugitangira nimbaraga iyo ecran yose yera (yerekana umweru), mugihe imbaraga zisanzwe nimbaraga zikoreshwa muburyo busanzwe.
Ni ubuhe bubasha rusange bwo kwerekana hanze LED?
Ukurikije ibicuruzwa n’ibicuruzwa bitandukanye, imbaraga zo hejuru zerekana ibara ryerekana amabara atandukanye ziratandukanye kuva 800W kugeza 1500W kuri metero kare.
Icyakabiri, uburyo bwo kubara imbaraga zimbaraga zo hanze zerekanwe kwerekana:
P igereranya imbaraga, U igereranya voltage, mpagarara kubigezweho.
Mubisanzwe amashanyarazi atanga amashanyarazi dukoresha ni 5V, amashanyarazi ni 30A na 40A;ibara rimwe ryerekanwe kwerekana ni modules 8 na 1 40A itanga amashanyarazi, naho amabara abiri yayoboye ecran ni modules 6 mumashanyarazi 1;
Urugero ruzatangwa hepfo.
Niba ushaka gukora metero kare 9 zo mu nzu P5 yerekana amabara abiri LED yerekana, bara imbaraga ntarengwa zisabwa.
Ubwa mbere, ubare umubare wibikoresho 40A bitanga amashanyarazi = 9 (0.244 × 0.488) /6=12.5=13 ibikoresho byamashanyarazi (integer, ukurikije ibipimo binini), biroroshye cyane, imbaraga ntarengwa P = 13 × 40A × 5V = 2600W.
Imbaraga z'itara rimwe = imbaraga z'itara 5V * 20mA = 0.1W.
Imbaraga za LED yerekana ibice = imbaraga z'itara rimwe * imyanzuro (umubare wa pigiseli itambitse * umubare wa pigiseli ihagaritse) / 2;imbaraga ntarengwa za ecran = imiterere ya ecran * umubare wamatara kumurongo * 0.1;Impuzandengo yingufu = ecran ya ecran * umubare wamatara kumurongo * 0.1 / 2;imbaraga nyazo za ecran = imiterere ya ecran * umubare wamatara kumurongo * 0.1 / umubare wa scan (scan 4, scan 2, scan 16, scan 8, static).
Uburyo bwo kubara imbaraga za LED yerekana ecran ni ukubara umubare wa du point, 0.3W / point * amanota yose nimbaraga zose, kandi imbaraga ntarengwa zikubye inshuro 1.3.
Impuzandengo y'imbaraga ni kimwe cya kabiri cyimbaraga ntarengwa.
Kandi buri mugozi wamashanyarazi ukeneye kureba umubare wamabati ya LED utwara, hamwe n amanota angahe, noneho imbaraga zose zirashobora kubarwa.
1. LED ibisabwa kugirango ikemurwe:
Hanze yo hanze yerekanwe (icara mu majyepfo urebe amajyaruguru):> 4000CD / M.2.
Mugaragaza imbere mu nzu:> 800CD / M.2.
Semi-imbere yayoboye module:> 2000CD / M.2.
2. Ibipimo bitatu byerekana hanze LED yerekana imbaraga:
Impuzandengo yingufu za ecran = imiterere ya ecran * umubare wamatara kumurongo * 0.1 / 2.
Imbaraga ntarengwa za ecran = imiterere ya ecran * umubare wamatara kumurongo * 0.1.,
Imbaraga nyazo za ecran = imiterere ya ecran * umubare wamatara kumurongo * 0.1 / umubare wa scan (scan 4, scan 2, scan 16, scan 8, static).…
Ibyavuzwe haruguru ni intangiriro ngufi yerekeye hanze LED yerekana imbaraga nuburyo bwo kubara, twizere ko bizagufasha.
Kubindi bisobanuro birambuye birambuye byerekanwe byerekanwe nyamuneka rekaYONWAYTECHitsinda rizi.
