Sezvo kushandiswa kwezviratidziro zve LED kunowedzera kupararira, magetsi emagetsi emagetsi e LED anowedzera kukoshesa uye ane hanya nevatengi. Wese munhu anoziva kuti zviratidziro zve LED zvinogadzirwa ne LED modules imwe neimwe, uye kumashure kwechidzitiro kwakabatana kuneLED magetsi ekupa, uye ipapo tambo yemagetsi uye mutsara wechiratidzo zvakabatana.
Saka maitiro ekuverenga huwandu hwemagetsi emagetsi e LED kuratidza skrini?
LED inoratidzira skrini modules inogadziriswa uye inogadzirwa nekubatanidza zvinhu zvakasvibirira senge LED mwenje mabhero, PCB edunhu mabhodhi, ICs, uye kits. Nheyo yekushanda ye LED inoratidzira skrini modules ndeyekuti inogara iripo IC inotyaira mwenje-emitting chip mu LED mwenje mabhero kuratidza mavara.
Panyaya yemuvara wekuratidzira, LED inoratidzira skrini modules yakakamurwa kuita marudzi matatu: rumwe ruvara, maviri-ruvara, uye yakazara ruvara. Panyaya yemhando yekushandisa, ma LED module akakamurwa kuita emukati mamodule uye ekunze mamodule.
Kazhinji kutaura, ikozvino ye-full-color LED modules yakakura, ikozvino ye-single-color and two-color LED modules iduku, ikozvino yekunze kwe LED modules yakakura, uye ikozvino yemukati LED modules iduku. Nekudaro, kana fekitori ichigadzirisa iyo "chena chiyero" cheiyo LED module, iyo inoshanda ikozvino yeyakajairwa imwe LED yekuratidzira skrini module kazhinji iri pazasi 10A.
Kutanga, isu tinofanirwa kuyera ikozvino yeiyo imwechete LED module.
Isu tinogona kushandisa multimeter kubatanidza kune dunhu kuyera iwo chaiwo maparamita eiyo LED module. Nhasi, isu tichatora iyo P10-4S yekunze LED kuratidza module semuenzaniso kutsanangura maitiro ekuyera iyo module yazvino paramita nhanho nhanho.
Nhanho 1, gadzirira midziyo uye zvinhu
Isu tinogadzirira akati wandei P10-4S kunze kwe LED kuratidza modules, multimeter (inogona kuyera DC ikozvino mukati me10A), waya akati wandei, tepi yemagetsi, waya strippers, LED kuratidza control kadhi, LED kuratidza magetsi.
Nhanho 2, batanidza nemazvo
Muchiyedzo ichi chekuyera, tinoshandisa multimeter se DC ammeter. Iyo yakawanda yakawanda ye multimeter yekuyera DC ikozvino ndeye 10A. Isu tinobatanidza iyo multimeter munhevedzano kudunhu reiyo LED module.
Iyo chaiyo wiring sequence ndeye:
1. Batanidza AC 220V kusvika kumagumo ekupinza emagetsi e LED (yakaenzana nebasa re transformer, kushandura 220V AC kuita 5V DC)
2. Batanidza waya kubva padanda rakanaka rekubuda kunoguma kune dzvuku wire peni (positive pole) yemultimeter.
3. Sungai tambo yakatsvuka mugomba mutsvuku "10A" pane multimeter
4. Batanidza chinyoreso chewaya nhema kune tambo dzvuku (positive pole) yemodule tambo yemagetsi
5. Batanidza tambo yemagetsi module mumodule kazhinji
6. Batanidza tambo yakasviba (negative pole) yemodule tambo yemagetsi kumashure kune yakashata danda rekuguma kwekubuda kweiyo LED magetsi.
Danho rechitatu, kuyera kuverenga
Isu tinogona kuona kuti kana soketi yemagetsi yekupinza yakavharirwa mukati uye iyo yese LED inoratidzwa yakavhenekerwa, ikozvino yeimwe module haina kunyanyokura. Sezvo zvirimo zvekutamba zvachinja, kuverenga pamultimeter zvakare kunochinja, kunyanya kuchengetedza pa1-2A.
Isu tinodzvanya bhatani rekuyedza pane kadhi rekudzora kuti uchinje iyo skrini uye uwane inotevera data yekuyedza:
a. Ikozvino ndiyo yakakura apo "ese machena", anenge 5.8A
b. Ikozvino ndeye 3.3A mune dzvuku uye girini nyika
c. Ikozvino ndeye 2.0A mublue state
d. Kana uchidzokera kune zvakajairika chirongwa chemukati, ikozvino inoshanduka pakati pe1-2A.
Nhanho 4, kuverenga
Iye zvino isu tinogona kuverenga kuti mangani ma LED modules iyo LED magetsi inogona kutakura zvichibva pachiyero chepamusoro mhedzisiro. Iyo chaiyo yekuverenga nzira ndeiyi: Imwe neimwe LED magetsi emagetsi anonyanya kushandura. Tichitora yedu inowanzo shandiswa 200W switching power supply semuenzaniso, mugadziri anopa mitoro yekutakura se "output 5V40A" uye "inoshanda shanduko mwero 88%".
Simba rinoshanda rinopihwa neLED switching power supply: P=88% x 200W=176W. Zvinoenderana neformula: P = UI, iyo yakanyanya simba yekushandisa yeimwe LED module inogona kuwanikwa: P1 = UI = 5V x 5.8A = 29W. Kubva pane izvi, huwandu hwemamodules anogona kutakurwa neiyo LED switching power supply inogona kuverengerwa: n=P/P1=176W/29W≈6.069
Kubva pane kuverenga pamusoro, tinoziva kuti kana nhamba ye LED modules inotakurwa isingapfuuri 6, magetsi e LED haana kuwandisa.
Ikozvino isu takaverenga ndiyo yakanyanya ikozvino apo LED module "ese machena", uye kushanda ikozvino panguva yekutamba kwakajairika kazhinji inongova 1 / 3-1 / 2 yehuwandu huripo. Nokudaro, nhamba yemitoro inoverengwa maererano nehuwandu hwemazuva ano ndiyo nhamba yakachengeteka yekutakura. Zvino mangani mamodule e LED anobatanidzwa pamwe chete kuti agadzire yakakura yakazara LED skrini yekuratidzira, uye yozopatsanurwa nenhamba iyi yakachengeteka inotakura, tinogona kuwana mangani emagetsi emagetsi e LED anoshandiswa muchiratidziro che LED.
