Qhov tseem ceeb Scenes Qhov chaw ua si LED zaub xa cov kev cuam tshuam
A Stadium LED zaubtsis yog khoom kim heev - nws yog lub plawv dhia ntawm kev ua si thiab cov xwm txheej. Los ntawm instant replays rau kev txhawb nqa kev sib hloov, cov ntxaij vab tshaus no ua haujlwm hauv peb qhov xwm txheej tseem ceeb:
Live ua replays- Siab- nrawm nrawm nrawm xav tau 1920Hz + refresh npaum li cas kom tsis txhob muaj dab.
Ntxuam kev koom tes- Ntawm -screen karaoke, hnia cams, thiab tiag - lub sijhawm stats boost huab cua.
Sponsor branding- Tig kev tshaj tawm digital ntawm lub quarters tsim cov nyiaj tau los hauv chaw ntau pob.
Kev siv thib ob suav nrogchaw ntau pob perimeter LED zaubboards (track-sab) thiabchaw ntau pob scoreboard LED zaubunits uas qhia cov nyob stands.
Tiag -Cov teeb meem hauv ntiaj teb (Thiab yog vim li cas ntau lub chaw ntau pob tau txais nws tsis raug)
| Teeb meem | Qhov tshwm sim |
|---|---|
| Tsawg brightness | Qhov screen yuav tsis nyeem tau nyob rau hauv tshav ntuj |
| Pom lub kaum sab xis tsis zoo | Cov rooj zaum sab pom ntxuav - tawm xim |
| Lub teeb liab qeeb | Replay lags 2+ vib nas this tom qab nyob ua yeeb yam |
| Inconsistent txee sealing | Los nag ua rau module tsis ua hauj lwm nruab nrab -game |
Cov lus: Plaub qhov ua tsis tiav ntawm chaw ntau pob LED zaub
Ntxiv qhov ntev -tail teeb meem:
sab nraum zoov chaw ua si LED screenoverheating nyob rau lub caij ntuj sov yam tsis muaj qhov cua zoo.
chaw ntau pob video zaub boardflickering nyob rau hauv chaw ntau pob teeb pom kev cuam tshuam.
chaw ntau pob LED ribbon boardpixel tso tawm tom qab 2 xyoos ntawm kev siv txhua hnub.
Cov tswv yim daws teeb meem rau txhua qhov teeb meem
Txoj Kev 1 – Brightness
XaivStadium LED zaubnrog tsawg kawg yog 6,500 nits rau cov chaw sab nraum zoov. RauNyob sab hauv tsev chaw ntau pob LED zaub(piv txwv li, basketball arenas), 1,500–2,500 nits txaus. Nco ntsoov nug rau nws pib -brightness sensors.
Txoj Kev 2 – Saib lub kaum sab xis
Xav tau 160℃kab rov tav / 140℃ntsug kev pab them nqi. SMD (Nto-Mounted Device - LEDs ntim rau hauv Circuit Court board nto) thev naus laus zis muaj qhov dav dua li DIP (Dual In-kab Pob - laus dua, hom LED loj).
Txoj Kev 3 – Tsawg latency
Siv fiber ntau optic teeb liab kis tau tus mob es tsis txhob CAT6 cables. Khaws qhov kawg - mus rau - xaus ncua qis dua 50ms. Rauchaw ntau pob scoreboard LED zaub, sync ntau lub rooj tsavxwm ntawm Genlock (synchronization teeb liab uas xauv lub sijhawm sijhawm hla cov ntxaij vab tshaus).
Kev daws 4 - Kev tiv thaiv huab cua
Cov chav nyob sab nraum zoov xav tau IP65 yam tsawg kawg nkaus. Rau cov daus- thaj chaw uas yooj yim, ntxiv cov cua sov rau hauvchaw ntau pob perimeter LED zaub. Rau kev nyab xeeb huab cua, tiv thaiv -condensation kua vents.
Txhais - Dab tsi yog qhov chaw ua si LED zaub?
A Stadium LED zaubyog ib qho loj- hom ntawv, siab- ci ntsa iab, huab cua- tiv taus LED npo tsim rau kev ua kis las thiab chaw lom zem. Tsis zoo li cov ntawv tshaj tawm kev lag luam, cov lus qhia tseem ceeb:
Siab refresh npaum li cas(1920Hz–3840Hz) rau kev qeeb qeeb - suab replays.
Dual -cim rov ua dua- Ob qhov chaw nkag tau khiav ib txhij. Yog tias ib qho ua tsis tiav, lwm tus yuav siv sijhawm tam sim.
Cov qauv vibration damping- Cov thav duab hlau nrog cov roj hmab gasket kom nqus cov neeg coob coob thiab cov ntses bass thaj tsam.
Glossary of Terms
SMD vs DIP- SMD tso RGB chips hauv ib pob, zoo dua rau kev saib ze. DIP muaj cov LEDs cais, muaj zog dua tab sis lub kaum sab xis.
Genlock- Lub sijhawm teeb liab uas ua rau ntau lub vijtsam thav duab- synchronized.
Kev ntsuas IP- Thawj tus lej=plua plav (6=plua plav- nruj). Tus lej thib ob=dej (5=dav hlau, 6=dav hlau muaj zog, 7=immersion ib ntus).
