Shaashadda hufan ee LED-ka-yar-yar waa badeecad cusub oo wanaajisay xallinteeda shaashadda dhaqameed ee nadiifinta magaca LED.Haddaba waa maxay kala-fogeynta aan dhihi karnaa sidii shaashad yar-yar?Marka farqiga dhibcaha LED-ka ee shaashadda hufan ee yar-yar uu ka hooseeyo P2.5, waxaan dhihi karnaa in LED-ga yar-yar uu yahay mid hufan.Waqtigan xaadirka ah, seddexda mushkiladood ee soo socda ee soo socda ee adeegsiga shaashadaha hufan ee LED-yada ee suuqa waxay u baahan yihiin in la hagaajiyo:
1. Kordhinta pixels dhintay oo ay sababtay hagaajinta tayada sawirka
Shaashadda daah-furnaanta LED-ka-yar-yar waxay ka kooban tahay laambad badan oo LED ah, qaybintuna waa cufan.Inta badan tirada laambada LED-ka ee aag kasta, ayaa sare u kacaysa tayada shaashadda hufan, iyo soo bandhigida faahfaahinta sawirka.Si kastaba ha ahaatee, cilado farsamo dartiis, shaashado yar yar oo hufan ayaa u nugul dhibco dhintay ee kuulka laambada.Guud ahaan, heerka cabbirka iftiinka dhintay ee LED-ka waxaa lagu xakameynayaa 3/10,000 gudahood, laakiin shaashadaha hufan ee LED-ka-yar, heerka dhimashada 3/10,000 waa xaddidan yahay.Heerka nalku ma dabooli karo baahida isticmaalka maalinlaha ah.Qaado P2-yar-pitch-ka-yar ee shaashadda hufan ee LED-ka tusaale ahaan, waxaa jira 250,000 kuul laambad halkii mitir laba jibaaran.Iyadoo loo maleynayo in bedka shaashadda uu yahay 4 mitir oo laba jibbaaran, tirada nalalka dhintay waxay noqon doonaan 25*3*4=300, taasoo keeni doonta khibrad daawasho aan saaxiibtinimo lahayn shaashadda caadiga ah.
Xalka: Laydhka dhintay guud ahaan waa sababta alxanka daciifka ah ee kuulka laambada.Dhinaca kale, tignoolajiyada wax soo saarka ee soo saaraha shaashadda hufan ee LED ma aha ilaa heer, waxaana jira dhibaato xagga kormeerka tayada.Dabcan, dhibaatada kuulka laambada ayaan meesha laga saarin.Sidaa darteed, soo-saarayaashu waa inay xakameeyaan tayada alaabta ceeriin iyadoo loo eegayo habka kormeerka tayada rasmiga ah, isla markaana ay la socdaan habka wax soo saarka ee meesha.Kahor intaadan ka tagin warshadda, waa inay sidoo kale samayso 72 saacadood oo tijaabo gabow ah, dib u habayn iyo hubiso dhibka iftiinka dhintay, oo hubi inay tahay badeeco u qalma ka hor inta aan la rarin.
2. Luminta miisaanka oo ay keento dhalaalka oo yaraada
Farqiga ugu weyn ee u dhexeeya codsiyada gudaha iyo dibadda waa isbeddelka iftiinka jawiga.Marka muraayadda hufan ee LED ay gudaha soo gasho, dhalaalkeeda ayaa loo baahan yahay, laakiin marka dhalaalka shaashadda hufan uu hoos u dhaco 600cd/㎡, shaashadu waxay bilaabataa inay muujiso khasaare cad oo cawl ah.Marka dhalaalku sii yaraado, lumista cawl sidoo kale way korodhaa.aad iyo aad u daran.Waxaan ognahay in heerka sare ee cawl, ay ka sii qani ah midabada lagu soo bandhigay shaashadda hufan, oo aad u jilicsan oo buuxa sawirka.
Xalka: Iftiinka shaashadu waxa uu ku haboon yahay iftiinka jawiga oo si toos ah ayaa loo hagaajin karaa.Ka fogow saameynta jawi aad u dhalaalaya ama mugdi badan si aad u hubiso tayada sawirka caadiga ah.Isla mar ahaantaana, shaashadda leh heer sare oo cawl ah ayaa la qaatay, heerka cawl ee hadda jira wuxuu gaari karaa 16bit.
3. Dhibaatada kululaynta ee ay keento daawashada dhow
Daraasaduhu waxay muujiyeen in habka beddelka tamarta ee muraayadaha LED-ka, waxtarka beddelka elektiroonigga ah ee ku-meel-gaadhka ah waa kaliya 20 ~ 30%, taas oo ah in la yiraahdo, kaliya 20 ~ 30% tamarta tamarta korontada ayaa loo beddelaa tamarta iftiinka, iyo inta soo hartay 70 ~ 80% tamarta.Dhammaan waxaa lagu cunaa qaabka shucaaca kulaylka, sidaas darteed, kulaylka bandhigga LED waa halis.Shaashadda hufan ee LED-ka-yar ee soo saarta kulaylka muddo dheer waxay sababi doontaa in heerkulka gudaha gudaha uu kordho.Shaqaalaha gudaha, joogida wakhti dheer waxay noqon doontaa mid aan raaxo lahayn, iyo xitaa fadhiista meel aad u fog, way adagtahay wakhti dheer.Ku hay dabeecad wanaagsan qandhada hoosteeda.
Xalka: Isticmaalka tamarta tayada sare leh ee tayada sare leh waxay xaqiijin kartaa heerka sare ee isbeddelka elektiroonigga ah, taas oo yaraynaysa saameynta kulaylka.
Haddii saddexdan mushkiladood ee waaweyn ee muraayadaha hufan ee LED-ka-yar-yar si habboon loo xalliyo, ma saameyn doonto khibradda isticmaalka muraayadaha LED-ka.Haddii aad rabto inaad wax badan ka ogaato shaashadaha hufan ee LED, fadlan fariin u dhaaf oo noo sheeg
