alakaʻi hōʻike kiʻi

Ke hoʻomau nei ka ulu ʻana o ka ʻenehana LED, ke pāʻani nei ʻo LED Posters i kahi kuleana koʻikoʻi ma nā kahua o ka hōʻike hoʻolaha a me ka hoʻolaha ʻike. Ma muli o kā lākou mau hiʻohiʻona hiʻohiʻona kūʻokoʻa a me nā hiʻohiʻona noiʻi maʻalahi, ʻoi aku ka nui o nā ʻoihana a me nā mea kālepa i hoʻomohala i kahi hoihoi nui ike kumukūʻai o ka hōʻike LED poster. E hāʻawi kēia ʻatikala i kahi kikoʻī kikoʻī o ke ʻano kumu kūʻai o nā leka uila LED e kōkua iā ʻoe e hoʻomaopopo i kāna ʻano kumu kūʻai a hāʻawi i kahi alakaʻi koho e kōkua iā ʻoe i ka hoʻoholo ʻana i nā hoʻoholo kūʻai.

1. He aha nā kumukūʻai no nā leka uila LED - alakaʻi wikiwiki

ʻO ka mea maʻamau, ʻokoʻa nā kumukūʻai o nā leka uila LED maʻamau500 a 2000 USD. Hoʻololi ke kumukūʻai ma muli o nā mea like me ka brand of LED diodes, pixel pitch, refresh rate, etc. San'an Optoelectronics LED diodes. ʻOkoʻa nā kumu kūʻai o nā kukui hōʻike LED poster ma muli o nā ʻokoʻa o ka maikaʻi, ka hana, a me ke kūlana mākeke, ʻike ʻia.

Hāʻawi ka ʻenehana LED i ka mālamalama maikaʻi, ka ʻokoʻa, a me ka ʻike. ʻO nā kumukūʻai hōʻike leka uila LED mai$1,000 a i $5,000 a ʻoi aku paha.

Eia nā kumu ʻē aʻe e pili ana i nā kumukūʻai o nā leka uila LED

1.1 IC Drive

ʻO ka IC drive kahi mea koʻikoʻi o nā pale pepa LED, e pili pono ana i ka hopena hōʻike a me ke kumukūʻai. Hiki i nā IC drive kiʻekiʻe ke hāʻawi i ka mana pololei a me nā hōʻike paʻa, e hōʻemi ana i nā helu hāʻule a hoʻonui i ke ola. ʻO ke koho ʻana i nā mea hoʻokele IC maikaʻi ʻaʻole wale e hoʻonui i ka pololei o ka waihoʻoluʻu a me ka like ʻana o ka mālamalama akā e hōʻemi pono i nā kumukūʻai mālama. ʻOiai ʻoi aku ka nui o ke kumukūʻai, ʻoi aku ka maikaʻi o ka IC drive e hoʻopakele iā ʻoe i nā koina mālama i ka wā lōʻihi a hoʻonui i ka ʻike mea hoʻohana.

1.2 Lei kukui LED

ʻO ke kumukūʻai o nā pahu kukui LED ma nā leka uila he mea maʻamau ia o nā mea nui o nā kumukūʻai holoʻokoʻa.

Hāʻawi nā pahu kukui LED Premium i ka ʻōlinolino ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi o ka waihoʻoluʻu ʻana, a me ka lōʻihi o ke ola ʻana, he mea koʻikoʻi loa ia no nā kaiapuni waho a me nā wahi kiʻekiʻe. ʻO nā pahu kukui kukui LED maʻamau i loaʻa ma ka mākeke ʻo Samsung, Nichia, Cree, a me nā mea ʻē aʻe, nona nā kukui LED i hoʻohana nui ʻia i nā hōʻike LED kiʻekiʻe ma muli o ko lākou ʻano a me ke kūpaʻa.

1.3 Nā Papa Hoʻolaha LED

ʻO nā mea o ke keʻena hōʻike LED ka nui o ke kila, alumini alumini, magnesium alloy, a me ka alumini make-cast. ʻAʻole hoʻoholo wale nā ​​mea ʻokoʻa i ke kaumaha o ka hōʻike akā pili pū kekahi i ke kumukūʻai.

'Oko'a ke kaumaha o nā ke'ena hō'ike leka uila LED ma muli o ka mea. ʻOi aku ke kaumaha o nā keʻena kila, ʻo ke kaumaha ma kahi o 25-35 kilokani no ka mika square, kūpono no nā manawa e koi ana i ka ikaika kiʻekiʻe; ʻoi aku ka maʻalahi o nā keʻena alumini alumini, ke kaupaona ʻana ma waena o 15-20 kilokani i kēlā me kēia mika square, hoʻohana nui ʻia i ka hapa nui o nā papahana; ʻO nā cabinets magnesium alloy ka māmā, ke kaumaha ma kahi o 10-15 kilokani i kēlā me kēia mika square, kūpono no nā noi kiʻekiʻe e koi ana i ka hoʻēmi kaumaha nui; ʻO nā keʻena alumini make-cast e moe ana ma waena, e kaupaona ana ma kahi o 20-30 kilokani no ka mika square, e hāʻawi ana i ka ikaika maikaʻi a me ke kūpaʻa. ʻO ke koho ʻana i nā mea kūpono e pono ai ka noʻonoʻo piha ʻana i nā pono o ka papahana a me ke kālā.

1.4 Papa PCB

ʻO ke kumu kūʻai o nā papa PCB mai ke ʻano o nā mea maka a me ka helu o nā papa.

Loaʻa i nā mea papa PCB maʻamau nā papa kaapuni fiberglass FR-4 a me nā laminates copper-clad (CCL), me CCL ma mua o nā papa kaapuni fiberglass FR-4. ʻOi aku ka maʻamau o nā papa kaapuni fiberglass FR-4 a emi ke kumu kūʻai, akā ʻoi aku ka maikaʻi o ka CCL i ka lōʻihi a me ka lawe ʻana i nā hōʻailona.

Hoʻohui maikaʻi ʻia ka helu o nā papa i nā modula hōʻike LED me ke kumukūʻai. ʻOi aku ka nui o nā papa i loaʻa i kahi module, ʻoi aku ka haʻahaʻa o ka hāʻule ʻole, a ʻoi aku ka paʻakikī o ke kaʻina hana. ʻOiai ke hoʻonui nei nā hoʻolālā multi-layer i nā kumukūʻai hana, hoʻomaikaʻi nui lākou i ka paʻa a me ka hilinaʻi o nā hōʻike LED, ʻoi aku ka mea nui i nā hōʻike LED nui a me ka hoʻonā kiʻekiʻe. No laila, i ke koho ʻana i nā modula hōʻike LED, ʻo ke koho ʻana o nā papa a me nā mea e pili pono i nā kumukūʻai, hilinaʻi, a me ka hana o nā leka uila LED.

1.5 LED mana lako

ʻO ka lako mana LED, ma ke ʻano he mea nui o nā leka uila LED, he hopena hiki ʻole ke hōʻole ʻia i nā kumukūʻai. Loaʻa i nā lako mana LED kiʻekiʻe ka volta a me nā mana hoʻopuka o kēia manawa, e hōʻoiaʻiʻo ana i ka hana paʻa o nā diodes LED, e hōʻemi ana i nā pilikia pōʻino, no laila e hoʻolōʻihi i ke ola lawelawe, ʻoi aku ka nui o ke kumukūʻai. I kēia manawa, pono e kūlike ka mana o ka mana o ka mana me nā kikoʻī a me ke ʻano hoʻohana o ka hōʻike LED poster. ʻO nā lako mana kiʻekiʻe a maikaʻi ke kumukūʻai. No ka laʻana, koi nā mea hoʻolaha LED waho i nā lako mana wai ʻole e hoʻololi i nā kaiapuni paʻakikī a me nā hana haʻahaʻa kiʻekiʻe, e hoʻonui ai i nā kumukūʻai holoʻokoʻa o nā leka uila i hoʻohālikelike ʻia me nā lako mana maʻamau no nā pale pale liʻiliʻi LED liʻiliʻi. ʻO ka nui o ka hōʻike LED poster ma 640192045mm maʻamau ka nui o ka hoʻohana ʻana i ka mana ma kahi o 900w no ka mika square a me ka awelika hoʻohana mana ma kahi o 350w no kēlā me kēia mika square.

2. Pehea e helu ʻia ai ke kumukūʻai o nā leka uila LED?

ʻO 1920 x 640 x 45 mm ka nui maʻamau o ka leka uila LED.

Inā makemake ʻoe e hoʻopilikino i ka nui, e kelepona wale i ka mea hana. Kākoʻo ka hōʻike LED poster a RTLED i ka hoʻopili ʻana, e ʻae iā ʻoe e hoʻolālā i ka wahi hōʻike e like me kou wahi.

2.1 Pūnaehana Mana LED

ʻO ka hoʻonohonoho ʻana a me ka nui o nā kāleka hoʻokipa a me nā kāleka hoʻouna he mau mea hoʻoholo i nā kumukūʻai pale LED.

ʻO ka maʻamau, inā ʻoi aku ka liʻiliʻi o ka wahi hoʻolaha LED, e like me 2 - 3 mau mika square, hiki iā ʻoe ke koho i kahi kāleka hoʻouna Novastar MCTRL300 maʻamau i hui pū ʻia me nā kāleka hoʻokipa MRV316. ʻO ke kumukūʻai o ke kāleka hoʻouna ma kahi o 80−120 USD, a ʻo kēlā me kēia kāleka loaʻa ke kumukūʻai ma kahi o 30−50 USD, hiki ke hoʻokō i ka hoʻouna ʻana i nā hōʻailona kumu a hōʻike i nā koi mana ma ke kumu kūʻai haʻahaʻa.

No nā pale pale P2.5 nui aʻe, no ka laʻana, ʻoi aku ma mua o 10 mau mika square, pono e hoʻohana i ke kāleka hoʻouna Novastar MCTRL660 me nā kāleka hoʻokipa MRV336. ʻO ke kāleka hoʻouna MCTRL660, me ka hiki ke hoʻoili ʻikepili ʻoi aku ka ikaika a me nā hoʻolālā interface lehulehu, nā kumukūʻai ma kahi o 200−300 USD, aʻo kēlā me kēia kāleka loaʻa MRV336 ma kahi o 60−80 USD. Mālama kēia hui i ka hoʻouna ʻana i ka hōʻailona kūpaʻa a maikaʻi no nā pale nui.

E hoʻonui nui ʻia ke kumukūʻai o nā kāleka hoʻomalu me ka piʻi ʻana o ka nui a me ke kumukūʻai ʻāpana, a laila e hoʻonui ai i nā kumukūʻai o nā leka uila LED.

2.2 Pika Pika

Pili kēia i kāu mamao nānā.

Hāʻawi ʻo RTLED i ka P1.86mm a i ka P3.33mm LED posters. A ʻo ka liʻiliʻi o ka pitch pixel, ʻoi aku ka kiʻekiʻe o ke kumukūʻai.

2.3 Hoʻopili

RTLEDHāʻawi i nā koho ʻelua: nā pahu lāʻau a me nā pahu lele, kēlā me kēia me nā hiʻohiʻona ʻokoʻa a me nā kumu kūʻai.

Hoʻohana ka pahu pahu pahu lāʻau i nā mea lāʻau ikaika, e hāʻawi ana i ka hoʻoponopono paʻa a me ka hilinaʻi no nā huahana, me ka pale ʻana i nā collisions, vibrations, a me nā mea ʻē aʻe o waho i ka wā o ka transit, me nā kumukūʻai haʻahaʻa, kūpono i nā mea kūʻai aku i kekahi mau koi no ka pale a nānā i ke kumukūʻai- pono.

Hāʻawi ka pahu pahu mokulele i kahi kiʻekiʻe o ka pale a me nā pono portability, me nā mea waiwai maikaʻi loa a me nā mea hana kiʻekiʻe, ka hoʻolālā ʻana i loko kūpono, e hāʻawi ana i nā leka uila LED i ka mālama piha, kūpono loa no nā hiʻohiʻona noi kiʻekiʻe me ka palekana o ka huahana a me nā pono o ka halihali, ma kahi ʻoi aku ka kiʻekiʻe o ke kumukūʻai, e hōʻemi ana i kou hopohopo i nā kaʻina lawe a me ka mālama ʻana.

3. hopena

Ma kahi huaʻōlelo, ʻokoʻa ke kumukūʻai o nā leka uila LED ma muli o ka hoʻonohonoho a me nā ʻāpana. ʻO ke kumu kūʻai maʻamau mai$1,000 a i $2,500. Inā makemake ʻoe e kau i kahi kauoha no ka pale pale LED,e waiho wale mai ia makou.
