Dulqaadka midabka SDCM waxa loola jeedaa kala duwanaanshaha midabka u dhexeeya alwaaxyada kala duwan ee ay ka soo baxaan isha iftiinka midabka ee kala duwanaanshaha midabka ee ay arkaan isha bini'aadamka, oo inta badan lagu muujiyo qiimayaal tirooyin ah, oo sidoo kale loo yaqaan kala duwanaanshaha midabka. Dulqaadka midabka SDCM waa mid ka mid ah tilmaamayaasha muhiimka ah si loo cabbiro joogteynta midabka alaabta iftiinka LED. Codsiyada iftiinka LED-ka, cabbirka dulqaadka midabka SDCM wuxuu si toos ah u saameeya tayada iyo xasilloonida saameynta iftiinka.
Habka xisaabinta ee dulqaadka midabka SDCM waa in loo beddelo farqiga isku-dubarid ee u dhexeeya isha iftiinka la tijaabiyay iyo isha iftiinka caadiga ah ee loo beddelo qiimaha SDCM iyadoo loo eegayo jaantuska chromaticity CIE 1931. Inta yar ee qiimaha SDCM, ayaa ka sii wanagsan joogteynta midabka, iyo weynaanta kala duwanaanshaha midabka. Xaaladaha caadiga ah, alaabooyinka leh qiimaha SDCM ee gudaha 3 ayaa loo tixgaliyaa inay yihiin alaabooyin leh midab wanaagsan, halka kuwa ka weyn 3 ay u baahan yihiin in la sii hagaajiyo.
Codsiyada nalalka LED-ka, joogteynta midabka ayaa saameyn muhiim ah ku leh xasilloonida iyo raaxada saameynta iftiinka. Haddii joogteynta midabka ee alaabta nalalka LED ay liidato, midabka meelaha kala duwan ee isla goobta ayaa si weyn u kala duwanaan doona, saameynaya khibradda muuqaalka ee isticmaalaha. Isla mar ahaantaana, alaabooyinka midabkoodu liidato waxay sidoo kale keeni karaan dhibaatooyin sida daalka aragga iyo midabka midabka.
Si loo hagaajiyo joogteynta midabka ee alaabta iftiinka LED, waxaa lagama maarmaan ah in laga bilaabo dhinacyo badan. Ugu horreyntii, tayada chip LED waxay u baahan tahay in si adag loo xakameeyo si loo hubiyo joogteynta midabka midabka LED-ka. Marka labaad, xakamaynta tayada adag ayaa looga baahan yahay alaabta nalalka LED si loo hubiyo in joogteynta midabka badeecad kasta ay isku mid tahay. Ugu dambeyntii, nidaamka iftiinka LED wuxuu u baahan yahay in la nadiifiyo oo la hagaajiyo si loo hubiyo joogteynta midabka u dhexeeya ilo iftiin kala duwan.
Marka la soo koobo, dulqaadka midabka SDCM waa mid ka mid ah tilmaamayaasha muhiimka ah si loo cabbiro joogteynta midabka alaabada nalalka LED, taas oo door muhiim ah ka ciyaarta hagaajinta tayada iyo xasiloonida saameynta iftiinka ee alaabta iftiinka LED. Si loo hagaajiyo joogteynta midabka ee alaabta nalalka LED, waxaa lagama maarmaan ah in laga bilaabo dhinacyo badan si loo hubiyo in tayada chips LED, tayada alaabta nalalka LED iyo edbinta ee nidaamka iftiinka LED buuxiyo heerka.
