Chiyambi cha Zojambula Zakunja za LED

Makanema akunja a LED asintha zotsatsa komanso zowonetsera pagulu, kutulutsa zowoneka bwino zomwe zimakhala zowonekera ngakhale dzuwa litakhala. Ndi milingo yowala yomwe ikufika pa 5,000 mpaka 8,000 nits, zowonera izi zidapangidwa kuti zizigwira ntchito 24/7 nyengo zonse. Koma kodi nchiyani chimene chimapangitsa kuti zodabwitsa zaumisiri zimenezi zikhale zogwira mtima kwambiri?

Zigawo Zazikulu za Zojambula Zakunja za LED

1. Ma modules a LED: Maziko a Visual Excellence

Pakatikati pa zowonetsera zakunja za LED pali ma module amphamvu a LED okhala ndi:

• Miyezo yopanda madzi ya IP65 mpaka IP68

• Zovala zosagwira UV kuti zisamafote

• Nyumba zokhala ndi aluminiyamu zokhazikika zokhazikika

2. Pixel Pitch ndi Kusintha

Pixel pitch imatsimikizira kusanja ndi mtunda wowonera pazenera la LED. Zowonetsera panja nthawi zambiri zimagwiritsa ntchito ma pixel pakati pa P10 ndi P20, ndi pixel iliyonse yomwe ili ndi:

• Chip chofiyira cha LED (wavelength: 620-630nm)

• Chip chobiriwira cha LED (wavelength: 515-535nm)

• Chip cha blue LED (wavelength: 460-470nm)

3. Njira Zoyendetsera Zotentha

Pofuna kuthana ndi zovuta zakunja, zowonetsera za LED zili ndi:

• Njira zoziziritsira bwino za convection

• Zovala za Thermally conductive zochotsa kutentha

• Zowunikira kutentha zosinthira zowunikira zokha

Momwe Zowonetsera Zakunja za LED Zimapangira Mitundu

Zowonetsera zakunja za LED zimagwiritsa ntchito ukadaulo wapamwamba wa PWM (Pulse Width Modulation) kuti akwaniritse:

• Kuzama kwamtundu wa 16-bit, kupanga mithunzi yopitilira 65,000 pamtundu uliwonse

• Kukonza kwamagetsi kwa gamma kuti kukhale kowala bwino

• Kusiyanitsa kwakukulu kosinthika (5000: 1 kapena kupitilira apo)

Kusakaniza Mitundu M'malo Akunja

Kulondola kwamtundu kumasungidwa ngakhale m'mikhalidwe yovuta mwa:

• Zowunikira zenizeni zenizeni zenizeni

• Kusintha kwa kutentha kwamitundu nthawi zosiyanasiyana za tsiku

• Mankhwala oletsa glare kuti achepetse kuwunikira

Mawonekedwe Osagwirizana ndi Nyengo Zowonetsera Panja za LED

Zopangidwira kuti zikhale zolimba, zowonetsera zakunja za LED zimapangidwira kuti zipirire nyengo yovuta kudzera:

• Mafelemu a aluminiyamu osachita dzimbiri

• Zovala zovomerezeka pazigawo zamagetsi

• Njira zophatikizira ngalande kuti madzi asachuluke

• Chitetezo chamagetsi mpaka 20kV pachitetezo chamagetsi

Control Systems for Outdoor LED Screens

Mayankho amakono akunja a LED amakhala ndi machitidwe owongolera, kuphatikiza:

• Makhadi olandirira kawiri-osagwira ntchito mosadodometsedwa

• Kasamalidwe kazinthu zozikidwa pamtambo pazosintha zakutali

• Kuwunika zenizeni zenizeni ndi kuzindikira zolakwika

• Kuyang'anira mphamvu kuti muwonjezere kugwiritsa ntchito mphamvu

Ubwino Wokonza Zowonetsera Zakunja za LED

Zowonetsera zakunja za LED zidapangidwa kuti zizikonzedwa mosavuta ndi zinthu monga:

• Makanema olowera kutsogolo kuti akonze mwachangu

• Ma module otenthetsera osinthika osasokoneza ntchito

• Ma algorithms olipira ma pixel kuti akonze ma pixel akufa

Mafunso Ofunsidwa Kawirikawiri

Q: Kodi zowonetsera zakunja za LED zimatha nthawi yayitali bwanji?

A: Ndi chisamaliro choyenera, zowonetsera zakunja za LED nthawi zambiri zimatha maola 80,000 mpaka 100,000, ndikuwonongeka kochepa kowala.

Q: Kodi zowonera zakunja za LED zitha kugwira ntchito nyengo yotentha?

A: Inde, zowonetsera zapamwamba zakunja za LED zidapangidwa kuti zizigwira ntchito bwino kutentha kuyambira -40 ° C mpaka 60 ° C.

Q: Ndi mphamvu ziti zowonetsera zakunja za LED?

A: Kuyika kwa LED kwakunja kumagwiritsa ntchito magetsi a magawo atatu okhala ndi malamulo odziyimira pawokha komanso majenereta osunga zobwezeretsera kuti akhale odalirika.

Kutsiliza: Tsogolo la Ukadaulo Wakunja wa LED

Monga ukadaulo wakunja wa LED ukupita patsogolo, mabizinesi amatha kuyembekezera zatsopano monga:

• Zowonetsera zowonekera za LED zophatikizira zomangamanga

• Mapangidwe opindika opindika amitundu yosiyanasiyana

• Mayankho a LED olumikizana nawo

• Zowonetsera za LED zoyendetsedwa ndi dzuwa kuti zizigwira ntchito mosadukiza

Pomvetsetsa ukadaulo wa zowonera zakunja za LED, mabizinesi amatha kupanga zisankho zanzeru kuti apange zowonera zomwe zimakopa omvera ndikupirira kuyesedwa kwanthawi.
