Waa maxay midabaynta iyo SDCM?

Midabaynta midabku waa habka loo kala saarayo LED-yada iyadoo lagu saleynayo midabkooda saxnaanta, dhalaalka, iyo joogteynta. Tan waxaa loo sameeyaa si loo hubiyo in LED-yada loo isticmaalo hal shay ay leeyihiin muuqaal midab iyo dhalaal la mid ah, taasoo keentay midab iftiin iyo dhalaal joogto ah.SDCM midabada LED-yada kala duwan. Qiimaha SDCM ayaa had iyo jeer loo isticmaalaa in lagu qeexo joogteynta midabka LED-yada, gaar ahaan xariijimaha LED.

Hoos u dhaca qiimaha SDCM, ayaa ka sii fiicnaanaya saxnaanta midabka LED-yada iyo joogteynta. Tusaale ahaan, qiimaha SDCM ee 3 wuxuu muujinayaa in farqiga u dhexeeya midabka labada LED uu si dhib yar loo arki karo isha bini'aadamka, halka qiimaha SDCM ee 7 uu muujinayo inay jiraan isbeddello midab la garan karo oo u dhexeeya LED-yada.

Qiimaha SDCM ee 3 ama ka hooseeya ayaa sida caadiga ah loo tixgaliyaa inuu yahay kan ugu fiican ee fiilooyinka LED-ka ee aan biyuhu celin karin. Tani waxay dammaanad qaadaysaa in midabada LED-ku ay yihiin kuwo joogto ah oo sax ah, taas oo muhiim u ah soo saarista lebbiska iyo iftiinka tayada sare leh. Si kastaba ha noqotee, waxaa muhiim ah in la ogaado in qiimaha SDCM ee hoose uu sidoo kale la imaan karo sumad qiimo weyn, marka markaad dooranayso xariijin LED leh qiime gaar ah oo SDCM ah, waa inaad tixgelisaa miisaaniyadaada iyo sidoo kale shuruudaha codsigaaga.

SDCM (Standard Deviation of Color Matching) waa cabirka aiftiinka LEDjoogteynta midabka isha. spectrometer ama colorimeter ayaa loo baahan doonaa si loo qiimeeyo SDCM. Waa kuwan tallaabooyinka la qaadayo:

1. Diyaari ishaada iftiinka adiga oo shid xariijinta LED-ka oo u ogolow inay kululaato ugu yaraan 30 daqiiqo.
2. Geli isha iftiinka qol mugdi ah: Si aad uga fogaato faragelinta ilaha iftiinka dibadda, hubi in aagga imtixaanku uu mugdi yahay.
3. Cabbir spectrometer kaaga ama midabkaaga: Si aad u qiyaasto qalabkaaga, raac tilmaamaha soo saaraha.
4. Cabir isha iftiinka: u hel qalabkaaga meel u dhow xariijinta LED-ka oo qor qiimaha midabka.

Dhammaan xariijinteenu waxay ka gudbi karaan imtixaan tayo leh iyo imtixaan shahaado ah, haddii aad u baahan tahay wax la habeeyey, fadlannala soo xidhiidhaad iyo aad ayaan ugu faraxsanahay inaan caawino.
