1. Waa maxay LED?
LED waa soo-gaabista diode iftiin bixisa. Mabda'a tignoolajiyada iftiinka iftiinka LED waa in walxaha semiconductor qaarkood ay iftiimin doonaan iftiin mawjadaha dhererka gaarka ah marka hadda la isticmaalo. Korontada noocan oo kale ah waxtarka beddelka iftiinka ayaa aad u sarreeya. Daawooyin kiimiko oo kala duwan ayaa lagu samayn karaa agabka loo isticmaalo si loo helo dhalaal kala duwan. Iyo xagal daawashada LED. Waa shaashad soo bandhigaysa qoraalka, garaafyada, sawirrada, animation, oraahyada suuqa, fiidiyowyada, calaamadaha muuqaalka iyo macluumaadka kale iyadoo la xakameynayo qaabka soo-bandhigidda ee dareerayaasha iftiinka soo saara.
2. Shaashadaha LED-yada waxaa ka mid ah noocyada soo socda.
Muujinta LED midabka buuxa . Midabka buuxa waxa kale oo loo yaqaan saddex midab oo asaasiga ah, unugga bandhiga ugu yar oo ka kooban saddexda midab ee aasaasiga ah ee casaanka, cagaarka iyo buluugga. Midab buuxa oo LED ah ayaa inta badan lagu isticmaalaa garoomada diyaaradaha, saldhigyada tareenada, shineemooyinka, xarumaha wax iibsiga iyo marxaladaha.
Muujinta LED midab leh. Bandhiga laba midab ee LED wuxuu inta badan leeyahay casaan & cagaar, casaan & buluug. Waxaa ka mid ah, casaanka iyo cagaarka ayaa ah kuwa ugu badan. Bandhigyada midabada leh ayaa si weyn loogu isticmaalaa dhaqaalaha, isgaarsiinta, isbitaallada, amniga dadweynaha, suuqyada wax iibsiga, maaliyadda iyo canshuuraha.
Shaashad hal LED ah. Midabka LED-ka ee hal midab ayaa leh casaan, jaalle, cagaar, buluug, caddaan. Shaashadda LED-ka ee hal midab ah ayaa inta badan lagu isticmaalaa jardiinooyinka, meelaha baabuurta la dhigto iyo dukaamada tafaariiqda.
Horumarka heerka nolosha, baahida dadku way sii kordheysaa. Midab keli ah iyo muraayadaha LED-ka ee laba-midabka ah ayaa si tartiib tartiib ah loogu beddelay bandhigyo LED oo midab buuxa ah.
3. Halabuurka aasaasiga ah ee bandhigga.
Shaashadda LED-ku waxay ka kooban tahay armaajooyinka LED-ka (waa la kala qaybin karaa) iyo kaarka xakamaynta (kaarka soo dirida iyo kaarka qaadashada). Sidaa darteed, xakamaynta tirada ku habboon iyo armaajooyinka LED waxay samayn karaan cabbirro kala duwan oo LED ah si ay u daboolaan baahiyaha deegaan kala duwan iyo shuruudaha bandhigyada kala duwan.
4. cabbirka guud ee shaashadda LED.
Mid. Tilmaamayaasha jirka
Muuqaalka Pixel
Masaafada u dhaxaysa xarumaha pixels ku xiga. (Cutub: mm)
Cufnaanta
Tirada pixels halkii unug (cutub: dhibco/m2). Waxa jira xidhiidh xisaabeed gaar ah oo u dhexeeya tirada pixels iyo masaafada u dhaxaysa pixels.
Qaaciddada xisaabinta waa, cufnaanta=(1000/ masaafada dhexe ee pixel).
Cufnaanta sare eeMuujinta LED, sida uu sawirku u sii caddeeyo iyo inta yar ee fogaanta daawashada ugu fiican.
Fiican
Kala leexashada aan sinnayn ee pixels iyo modules LED marka la samaynayo shaashadda bandhigga LED. Fiicanaanshaha wanaagsan ee shaashadda soo-bandhigidda LED ma fududa inay keento midabka shaashadda LED-ka inuu noqdo mid aan sinnayn marka la daawanayo.
Laba. Tilmaamayaasha waxqabadka korantada
Miisaanka cawl
Heerka dhalaalka oo laga sooci karo kan ugu mugdiga badan ilaa kan ugu iftiimaya isla heerka dhalaalka muraayadda LED-ka. Miisaanka cawl waxa kale oo loo yaqaan miisaanka midabka ama miisaanka cawl, kaas oo tilmaamaya heerka dhalaalka. Tignoolajiyada soo bandhigida dhijitaalka ah, cabirka cawl ayaa ah qodobka ugu muhiimsan tirada midabada la soo bandhigay. Guud ahaan marka la eego, heerka sare ee cawl, ayaa hodan ku ah midabada la soo bandhigay, inta badan sawirka jilicsan, oo ay fududahay in la muujiyo faahfaahin qani ah.
Heerka cawl wuxuu inta badan ku xiran yahay nidaamka beddelka A/D. Guud ahaan waxa loo qaybiyaa wax cawlan, 8, 16, 32, 64, 128, 256 iwm.
Waqtigan xaadirka ah, bandhiga LED wuxuu inta badan qaataa nidaamka wax-qabadka ee 8-bit, taas oo ah, 256 (28) heerar cawl. Fahamka fudud ayaa ah in ay jiraan 256 dhalaal oo isbeddelaya madow ilaa caddaan. Isticmaalka saddexda midab ee aasaasiga ah ee RGB waxay sameyn kartaa 256 × 256 × 256 = 16777216 midab. Taas waxaa badanaa lagu tilmaamaa midabada 16 mega.
Dib u cusboonaysii inta jeer ee jir
Muujinta LED soo noqnoqda cusboonaysiinta macluumaadka shaashadda LED.
Guud ahaan, waa 25Hz, 30Hz, 50Hz, 60Hz, iwm
Cusbooneysii inta jeer
Muujinta LED-ku waxay tusinaysaa tirada jeer ee xogta si isdaba joog ah loo soo bandhigay ilbiriqsikiiba.
Caadiyan waa 960Hz, 1920Hz, 3840Hz, iwm. Markasta oo uu sareeyo heerka dib-u-cusboonaysiinta, ayaa muujinta muuqaalku aad u xasiloon tahay. Marka sawirka, heerka soo kicinta ee kala duwan ayaa leh farqi weyn.
5. Habka bandhiga
Nidaamka gidaarka fiidiyowga ee LED wuxuu ka kooban yahay saddex qaybood, isha isha, nidaamka xakamaynta iyo bandhiga LED.
Nidaamka xakamaynta shaqada ugu muhiimsan waa gelitaanka calaamadaha, beddelka, habka, gudbinta iyo xakamaynta sawirka.
Shaashadda LED-ka ayaa soo bandhigaysa waxa ku jira isha ishaarada.
