Muxuu U Qaban Karaa Muujinta Keydka Tamarta ee LED-ka Meheraddaada Xayeysiiska Dijital ah?
Muujinta hogaaminta badbaadinta tamarta, oo sidoo kale loo yaqaan shaashadda 'Anode Led Common'.
Chipset-ka LED-ku wuxuu leeyahay laba terminal, anode iyo cathode, iyo mid kasta oo midabkiisu buuxa yahay LEDs wuxuu ka kooban yahay saddex chipset LED ah. (cas, cagaar iyo buluug).
Nashqadaha caadiga ah ee Anode-ka caadiga ah, terminaalka dhammaan 3 (casaan, cagaar & buluug) LEDs waa la isku xiraa waxaana lagu daraa caabiyaha ballast dibadda si taxane ah oo leh LED-cas si loo ilaaliyo koronto joogto ah oo loo siman yahay hoos u dhaca tamarta dhammaan saddexda LEDs.
Tani waxay markaa ka dib yaraynaysaa meel bannaan oo loogu talagalay LED-yada taasoo ka dhigaysa garoon pixel adag si adag in la gaaro, halka ay sidoo kale tahay il kulaylka dheeraadka ah waxayna dardargelisaa habka gabowga waxayna yareysaa nolosha.
Muujinta tamarta-badbaadinta LED-ku waxay qabataa nashqadeynta nidaamka bandhiga LED midab-buuxa oo hooseeya.
Waa arjiga injineernimada is dhexgalka nidaamka kaas oo mideeya tignoolajiyada casriga ah ee kala duwan sida tignoolajiyada kombiyuutarka, tignoolajiyada elektiroonigga ah, tignoolajiyada indhaha, tignoolajiyada korantada iyo farsamada qaabdhismeedka.
Tiknooloojiyada Caadiga ah ee Cathode, goonida, korantada sahayda korontadu u go'an tahay ayaa la siiyaa LED-yada casaanka, cagaarka iyo buluuga ah ee awood u siinaya awooda la siiyo LED-ka cas in si gaar ah loo xakameeyo oo meesha looga saaro baahida loo qabo iska caabiyaha ballast.
Waqti dheer oo dib-u-ciyaarid, iyo isticmaalkeeda korontadu waa tilmaame muhim ah oo muujinaya welwelka macaamiisha LED-kaBandhig tamareed run ahaantii kuma tiirsana qalab gaar ah ama software horumarinta tignoolajiyada bandhigga, laakiin sidoo kale natiijada hal-abuurka tignoolajiyada ee xalka guud.
Tamar-badbaadinta muraayadaha xayeysiiska LED, P4MM dibadda, P5.926MM, P6.67MM, P8MM, P10MM, ka dib sannado cilmi-baaris iyo horumarin iyo isbarbardhigga tijaabada baaluq, kaydinta tamarta ee ka badan 40% marka la barbardhigo shaashadaha LED-dhaqameedka.
Yaraynta isticmaalka tamarta shaashadda shaashadda waa jihada horumarineed ee muhiimka ah ee tiknoolajiyada shaashadda LED.
Shaashadaha tamarta-badbaadinta LED-ku waxay qaataan fikradihii ugu dambeeyay ee naqshadeynta, iyagoo tixgelinaya arrimo ay ka mid yihiin qiimaha, waxayna naqshadeeyeen isticmaalka awoodda yar ee shaashadda LED-yada ee dhinacyada soo socda:
A: Nalalka casaanka, cagaarka iyo buluugga ahwaxaa ku shaqeeya 3.8V iyo hufnaanta sahayda wareejinta ayaa ka sareysa 85%.
B:Isticmaalka IC-badbaadinta tamarta-dhamaadka sare, Voltage aad u hooseeya kanaalka, VDS = 0.2V, si weyn u yaraynaysaa qiimaha danab ee wareegga wadista LED.
C: Isticmaalka kuulka laambada waaweyn ee 1 jeer ka iftiin badan kuwa caadiga ah ee LED, si ay hoos shuruudaha dhalaalka la mid ah, LED u baahan yahay wadista ka yar hadda, taas oo ah, isticmaalka korontada waa la dhimay.
D: Nidaamka xakamaynta caqliga lehsi madaxbanaan loo horumariyay waxay si toos ah u hagaajin kartaa dhalaalka shaashadda weyn ee LED iyadoo loo eegayo dhalaalka deegaanka dibadda, si aanay u khasaarin awoodda ama u keenin wasakh iftiin leh.
E:Muqaalada LED-ku-badbaadinta tamarta, oo ku salaysan muraayadaha LED-yada caadiga ah, waxay si nidaamsan u cusboonaysiiyeen saamaynta bandhigga iyo waxqabadka isticmaalka tamarta, si ay u isticmaalaan bandhigga LED-ka saamaynta isticmaalka iyo isticmaalka tamarta dhamaystiran ayaa gaadhay heerarka hogaaminta warshadaha.
Milkiilayaasha xayaysiisyadu waxay door bidaan bandhigyada LED oo leh hufnaan tamar wanaagsan.
Iyada oo la adeegsanayo tikniyoolajiyadda bandhigga LED-ka ee cathode-ka caadiga ah, heerkulka dusha sare ee shaashadda ayaa hoos u dhacay 12.4 darajo.
Xaaladdan oo kale waxay wax badan ka caawin kartaa midabaynta midabka iyo muddada dheer ee bandhigga LED.
Ka-faa'iideystayaasha tooska ah ee bandhigyada tamarta-badbaadinta LED-ka waa inay ahaadaan mulkiilayaasha xayaysiinta ee xayeysiinta bannaanka, ma aha oo kaliya isticmaalka muddada dheer ee nolosha, laakiin sidoo kale badbaadinta tamarta tamarta markii ay muddo dheer keentay gidaarka fiidiyooga.
La xidhiidh YONWAYTECH si aad u hesho xalka soo bandhigida badbaadinta tamarta habaysan.
