Aqoonta LED Qaybta 2: Waa maxay midabada ay leeyihiin LED-yadu?

LED cad

Dhowr kala duwanaansho ayaa la sameeyaa inta lagu jiro habka wax soo saarka ee nalalka LED ee la doortay.Meelaha chromatic ee loo yaqaan 'bin' waa jaangooyo toosan oo ku socda khadka BBL.Midabaynta midabku waxay ku xidhan tahay aqoonta-sida-sameeyaha iyo heerarka tayada.Xulasho weyn waxay ka dhigan tahay tayada sare, laakiin sidoo kale kharashyo badan.

Cadaan qabow

MacAdam Ellipses

Tixraac aagga jaantuska chromaticity ee ka kooban dhammaan midabada aan la kala saari karin, illaa celceliska isha bini'aadamka, midabka ku yaal bartamaha ellipse.Saxiixa ellipse wuxuu u taagan yahay farqiga muuqda ee chromaticity.MacAdam wuxuu muujinayaa farqiga u dhexeeya laba ilood oo iftiin leh oo loo maro ellipses, kuwaas oo lagu tilmaamay inay leeyihiin 'tallaabo' oo tilmaamaya weecanaanta caadiga ah ee midabka.Codsiyada meelaha ay ka muuqdaan ilaha iftiinka, dhacdadan waa in lagu xisaabtamaa sababtoo ah ellipse 3-tallaabo ah ayaa leh kala duwanaansho midab hoose marka loo eego 5-tallaabo.

LEDs midab leh

Jaantuska chromatic-ka ee CIE wuxuu ku salaysan yahay kala duwanaanshaha jireed ee isha bini'aadamka si loo qiimeeyo midabada iyadoo loo kala qaybinayo saddex qaybood oo chromatic ah oo aasaasi ah (habraaca saddex-midab): casaan, buluug iyo cagaar, oo ku yaal xagga sare ee qalooca jaantuska.Jaantuska chromatic CIE waxaa lagu heli karaa iyadoo la xisaabinayo x iyo y midab kasta oo saafi ah.Midabada spectrum (ama midabada saafiga ah) waxaa laga heli karaa qalooca dameeraha, halka midabada jaantusku ay yihiin midabyo dhab ah.Waa in la ogaadaa in midabka cad (iyo midabada kale ee aagga dhexe - midabada achromatic ama midabada cawl) ma aha midabyo saafi ah, oo aan la xiriirin karin mawjad gaar ah.
