Ha ts'ebeliso ea li-skrini tsa LED e ntse e ata le ho feta, litekanyetso tsa motlakase tsa li-skrini tsa LED li ntse li nkoa e le tsa bohlokoa le ho ameha ka bareki. Motho e mong le e mong oa tseba hore li-skrini tsa LED li entsoe ka li-module tsa LED ka bonngoe, 'me karolo e ka morao ea skrine e hokahane leMotlakase oa LED, ebe thapo ea motlakase le mohala oa lets'oao li hokahantsoe.
Joale u ka bala palo ea lisebelisoa tsa motlakase bakeng sa li-skrini tsa LED?
Li-module tsa skrini tsa LED li sebetsoa le ho hlahisoa ka ho kopanya lisebelisoa tse tala tse kang lifaha tsa lebone la LED, liboto tsa potoloho tsa PCB, li-IC le lisebelisoa. Molao-motheo oa ts'ebetso oa li-module tsa skrineng sa LED ke hore IC ea hajoale e khanna chip e ntšang khanya ka har'a lifaha tsa lebone la LED ho bonts'a mebala.
Mabapi le 'mala oa pontšo, li-module tsa skrine tsa LED li arotsoe ka mefuta e meraro:' mala o le mong, mebala e 'meli le mebala e feletseng. Mabapi le mefuta ea likopo, li-module tsa LED li arotsoe ka li-module tsa ka hare le li-module tsa ka ntle.
Ka kakaretso, li-module tsa LED tsa mebala e felletseng li kholo, 'mala o le mong le mebala e' meli ea li-module tsa LED li batla li le nyane, hajoale li-module tsa LED tsa kantle li kholo, 'me hajoale li-module tsa LED tsa kahare li batla li le nyane. Leha ho le joalo, ha fektheri e ntse e lokisa "tekanyetso e tšoeu" ea mojule oa LED, motlakase o sebetsang oa mochine o tloaelehileng oa skrine oa LED hangata o ka tlaase ho 10A.
Taba ea pele, re hloka ho lekanya hona joale ha module e le 'ngoe ea LED.
Re ka sebelisa multimeter ho hokahanya le potoloho ho lekanya litekanyetso tsa hona joale tsa module ea LED. Kajeno, re tla nka P10-4S outdoor LED display module e le mohlala ho hlalosa mokhoa oa ho lekanya mekhahlelo ea hona joale ea module mohato ka mohato.
Mohato oa 1, lokisetsa lisebelisoa le lintho
Re lokisetsa li-modules tse 'maloa tsa P10-4S tsa ka ntle tsa LED, multimeter (e ka lekanya DC hona joale ka hare ho 10A), lithapo tse' maloa, tepi ea motlakase, li-wire strippers, karete ea ho laola pontšo ea LED, matla a pontšo ea LED.
Mohato oa 2, hokela ka nepo
Tekong ena ea tekanyo, re sebelisa multimeter joalo ka ammeter ea DC. Sebaka se phahameng sa multimeter ho lekanya DC hajoale ke 10A. Re hokahanya multimeter ka letoto ho potoloho ea module ea LED.
Tatelano e khethehileng ea wiring ke:
1. Hokela AC 220V pheletsong ea phepelo ea motlakase ea LED (e lekanang le karolo ea transformer, ho fetola 220V AC ho 5V DC)
2. Hokela terata ho tloha polang e ntle ea pheletso ea sephetho ho pene e khubelu ea terata (positive pole) ea multimeter.
3. Kenya mohala o mofubelu ka har'a lesoba le khubelu la "10A" ho multimeter
4. Hokela pene e ntšo ea terata terateng e khubelu (positive pole) ea mohala oa motlakase oa module
5. Hokela thapo ea motlakase mojuleng ka tloaelo
6. Kopanya terata e ntšo (pholo e mpe) ea mohala oa motlakase oa mojule ho khutlela polong e mpe ea pheletso ea tlhahiso ea matla a LED.
Mohato oa 3, lekanya ho bala
Re ka bona hore ha sesebelisoa sa matla a ho kenya se kenngoa 'me pontšo eohle ea LED e khantšitsoe, hona joale ea mochine o le mong ha o moholo haholo. Ha litaba tsa ho bapala li fetoha, ho bala ho multimeter le hona hoa fetoha, ha e le hantle ho boloka ho 1-2A.
Re tobetsa konopo ea teko kareteng ea taolo ho fetola boemo ba skrine le ho fumana lintlha tse latelang tsa liteko:
a. Ea hona joale ke e kholo ka ho fetisisa ha "tsohle tse tšoeu", tse ka bang 5.8A
b. Hona joale ke 3.3A linaheng tse khubelu le tse tala
c. Hona joale ke 2.0A e putsoa
d. Ha u khutlela ho litaba tse tloaelehileng tsa lenaneo, hona joale ho fetoha pakeng tsa 1-2A.
Mohato oa 4, ho bala
Joale re ka bala hore na ke li-module tse kae tsa LED tseo motlakase oa LED o ka li tsamaisang ho latela liphetho tsa litekanyo tse kaholimo. Mokhoa o ikhethileng oa ho bala ke: Motlakase o mong le o mong oa LED ha e le hantle ke transformer. Ho nka mohlala oa rona oa 200W o sebelisoang hangata, moetsi o fana ka litekanyetso tsa mojaro e le "output 5V40A" le "sekhahla se sebetsang sa phetoho 88%".
Motlakase o sebetsang hantle o fanoang ke phepelo ea motlakase ea switching LED: P=88% x 200W=176W. Ho ea ka foromo: P = UI, boholo ba tšebeliso ea matla ea module e le 'ngoe ea LED e ka fumanoa: P1=UI=5V x 5.8A=29W. Ho tloha ho sena, palo ea li-module tseo motlakase o le mong oa LED o ka li tsamaisang li ka baloa: n=P/P1=176W/29W≈6.069
Ho ipapisitsoe le lipalo tse kaholimo, rea tseba hore ha palo ea li-module tsa LED tse tsamaisoang li sa fete 6, phepelo ea matla a LED ha e imetsoe.
Hona joale re e balang ke boholo ba hona joale ha mochine oa LED o le "bosoeu bohle", 'me hona joale ho sebetsa nakong ea ho bapala ho tloaelehileng hangata ke 1 / 3-1 / 2 feela ea boholo ba hona joale. Ka hona, palo ea meroalo e baloang ho latela boholo ba hona joale ke palo e sireletsehileng ea mojaro. Ebe ke li-module tse kae tsa LED tse kopantsoeng hammoho ho theha skrine e kholo ea pontšo ea LED, ebe e aroloa ke nomoro ena e sireletsehileng ea mojaro, re ka fumana hore na ho sebelisoa lisebelisoa tse kae tsa matla a LED skrineng sa pontšo ea LED.
Ho Fetola Phepelo ea Matla Phepelo ea Matla a sa Keneng Metsi Phepelo ea Matla a Motlakase haholo
Mofani oa phepelo ea matla a LED, haeba u thahasella lihlahisoa tsa rona, ka kopo ikopanye le rona!
