Ob tus neeg muag khoom hais txog qhov zoo li P4 sab nraum zoov daim ntawv tshaj tawm, thiab tus nqi sib txawv los ntawm 40%. Qhov kev thov twg yog qhov zoo dua? Rau ntau tus neeg yuav khoom, qhov no yog lub sijhawm tsis meej pem tshaj plaws ntawm tag nrho cov kev yuav khoom - cov lus qhia ntawm daim ntawv zoo ib yam, tab sis cov lus hais tsis sib xws. Qhov tseeb yog tias tus nqi LED zaub qhia txog ntau dua li pixel suab. Tom qab txhua qhov kev hais lus zaum cov khoom siv, LED ntim, tsim hluav taws xob, kev tiv thaiv dej, tswj cov khoom siv, thiab cov ntsiab lus tom qab muag. Kev nkag siab txog rau qhov no yuav tsis muab rau koj ib tus lej tas li - cov nqi lag luam hloov mus tas li - tab sis nws yuav cia koj nyeem cov lus hais nrog kev ntseeg siab, sib piv cov kev sib raug zoo, thiab qhov chaw qhov kev sib tham yog zais tus nqi tiag tiag.
Factor 1: Pixel Pitch Drives raug nqi ntau dua li lwm yam
Pixel suab - qhov kev ncua deb ntawm LED chaw, ntsuas nyob rau hauv millimeters - txiav txim seb muaj pes tsawg LEDs haum rau ib square meter. Nov yog lej uas piav qhia txog tus nqi sib txawv:
- P10 npo nqa 10,000 LEDs ib square meter
- P4 npo nqa 62,500 LEDs ib square meter
- P2.5 sab hauv tsev npo nqa 160,000 LEDs ib square meter
Hauv lwm lo lus, ib nrab ntawm lub suab kwv yees li plaub npaug ntawm LED suav, thiab LEDs yog tus nqi loj tshaj plaws ntawm ib qho module. Yog li ntawd, kev txiav txim siab daws teeb meem yuav tsum ua raws li kev pom nyob deb, tsis yog kev xav. Ib txoj kev P10 daim ntawv tshaj tawm saib los ntawm 50 meters muab qhov kev pom zoo tib yam li lub vijtsam P4 yuav - ntawm ib feem ntawm cov peev nyiaj. Lub caij no, lub rooj sib tham sab hauv tsev-chav saib pom ntawm 3 meters justifies ib tug nplua-pitch peev.
Yam 2: Txee Khoom Thiab Cov Qauv
Cov txee yuav zoo li cov thawv hlau yooj yim, tab sis lawv suav nrog qhov muaj txiaj ntsig ntawm qhov hnyav tag nrho, tus nqi, thiab lub neej ntev. Cov kev xaiv uas muaj xws li:
| Txee hom | Hom kev siv | Nqe nyiam | Kev lag luam tseem ceeb |
|---|---|---|---|
| Hlau (hlau) | Budget tsau installs | qis tshaj | Hnyav, qeeb qeeb rau xeb-tiv thaiv |
| Aluminium | Tsau + xauj mainstream | Nruab nrab | Lub teeb, zoo dua tshav kub dissipation |
| Tuag-cast aluminium | Rental / ncig saib | Siab dua | Rigging, ceev rigging, premium finish |
Aluminium raug nqi ntau dua li cov hlau, tab sis nws dissipates tshav kub zoo dua thiab txiav cov qauv thiab thauj khoom thauj. Rau cov nkoj xauj tsev, cov qauv tsim kev tuag txo qis kev teeb tsa kev ua haujlwm tom qab kev tshwm sim. Yog li, lo lus nug yog tsis yog "qhov twg hlau yog pheej yig dua" tab sis "uas tag nrho cov qauv haum rau kuv cov qauv siv."
Yam 3: LED Ntim - SMD, GOB, Thiab COB
Txoj kev LEDs tau ntim cov duab ob qho tib si nqi thiab durability:
- SMD (nto-mounted).: qhov kev xaiv loj tshaj plaws nrog rau kev sib tw loj tshaj plaws thiab tus nqi txaus nyiam tshaj plaws
- GOB (kua nplaum-on-board).: ntxiv cov txheej tiv thaiv pob tshab tshaj SMD modules, nce nqi nruab nrab thaum txhim kho kev cuam tshuam thiab noo noo tsis kam - nrov rau kev xauj tsev thiab kov-nruab nruab nrab
- COB (chip-on-board).: encapsulates lub nti ncaj qha, thawb chav tsev nqi siab dua; Hauv kev sib pauv, nws muab kev tiv thaiv zoo tshaj plaws thiab kev saib xyuas zoo rau cov phab ntsa hauv tsev
Rau feem ntau cov haujlwm txheem, SMD tseem yog qhov kev xaiv tsim nyog. Txawm li cas los xij, ib puag ncig uas muaj kev pheej hmoo ntawm lub cev - theem qiv, tsev kawm ntawv, chaw ua yeeb yam - feem ntau ua pov thawj rau GOB hwm.
Yam 4: Kev Tiv Thaiv Qib Thiab Thermal Design
Sab nraum tus nqi nce siab nrog kev tiv thaiv. IP65-rated txee yuav tsum tau ntim cov gaskets, cov khoom sib txuas tsis muaj dej, cov kav dej, thiab cov chaw kho corrosion; IP54 chav tsev sab hauv tsev tsis xav tau qhov no. Tshaj li qhov kev ntsuam xyuas nws tus kheej, thermal engineering teeb meem: cov ntxaij vab tshaus siab (8,000-10,000 nits rau hnub ci teeb pom kev zoo) xav tau cov khoom siv hluav taws xob hnyav dua thiab cov cua kub zoo dua, uas rov nce nqi. Qhov zoo siab, cov qauv siv hluav taws xob-cathode txuag hluav taws xob tuaj yeem raug nqi me ntsis ntawm kev yuav khoom tab sis rov qab qhov sib txawv los ntawm cov nqi hluav taws xob qis - qhov kev txiav txim siab them rau qhov tob los ntawm tag nrho-tus nqi-ntawm- tswv cuab xav.
Yam 5: Tswj System Thiab Accessories
Cov lus hais qee zaum ntsiag to inflates los ntawm cov saw tswj. Cov khoom kab ib txwm muaj xws li:
- Xa daim npav thiab txais daim npav
- Video processor (scaling, multi-input, HDR)
- Frame, sub-frame, thiab rigging qhov chaw
- Spare modules, khoom siv hluav taws xob, thiab cables
- Shipping case los yog davhlau ya nyob twg
Ob lub vijtsam tuaj yeem nqa cov nqi vaj huam sib luag zoo ib yam thaum sib txawv 10-15% hauv tag nrho vim tias ib qho kev tsocai muab cov kev tshaj lij video processors thiab cov khoom siv tiag tiag, thiab lwm qhov teev cov yam tsawg kawg nkaus. Nco ntsoov nug raws nraim li cas nkoj hauv lub thawv.
Yam 6: Kev Pabcuam Tomqab Tus Nqi
Thaum kawg, xav txog dab tsi tshwm sim tom qab xa khoom. Warranty ntev, spare-parts suav nrog ntim, tej thaj chaw deb-kev pab txhawb nqa, thiab firmware yooj yooj yim tag nrho cov nqi nqa rau cov chaw tsim khoom - thiab lawv qhov tsis tuaj yeem zais tus nqi rau koj. Kev hais lus siab dua me ntsis nrog cov ntaub ntawv pov thawj txoj cai thiab cov npe khoom seem meej feem ntau ua tau zoo tshaj qhov kev sib tw qis tshaj li tsib xyoos.
Yuav Ua Li Cas Sib Piv Quotes Ncaj Ncees
Ua ntej koj txiav txim ob nqe lus, normalize lawv ua ntej:
- Teem rau qhov sib npaug ntawm qhov sib npaug, lub txee loj, thiab qhov ntsuas kev tiv thaiv
- Paub meej LED hom thiab hom ntim hauv kev sau ntawv
- Xyuas seb qhov kev tswj hwm, processor, thiab cov khoom seem puas suav nrog
- Hloov txhua qhov kev tsocai rau tus nqi-ib-square-meter nrog rau cov khoom siv
- Weigh warranty thiab tom qab-muag cov lus teb rau hauv qhov kev txiav txim
Xaus
Tsis muaj cov chaw tsim khoom ncaj ncees tuaj yeem hais "ib tus nqi tseeb" rau lub vijtsam LED, vim muaj rau qhov sib cuam tshuam - suab, txee, ntim, kev tiv thaiv, tswj, thiab kev pabcuam - ua rau txhua qhov haujlwm sib txawv. Qhov koj tuaj yeem tswj tau yog qhov koj txawj ntse sib piv. Tuaj lub sij hawm hais, ua hauj lwm los ntawm daim ntawv teev npe saum toj no, thiab qhov sib txawv ntawm ob qhov kev muab yuav dheev ua rau kev txiav txim siab.
