Menene binning launi da SDMC?

Juriyar Launi: Wannan ra'ayi ne da ke da alaƙa da zafin launi. Kodak ne ya fara gabatar da wannan ra'ayi a masana'antar, wato British Deviation of Color Matching, wanda aka fi sani da SDCM. Wannan shine bambanci tsakanin ƙimar da aka ƙididdige ta kwamfuta da ƙimar da aka ƙididdige ta tushen haske. Wato, juriyar launi tana da takamaiman ma'ana ga tushen hasken da aka yi niyya.

Kayan aikin photochromic yana nazarin kewayon zafin launi na tushen hasken da aka auna, sannan yana tantance ƙimar zafin launi na yau da kullun. Lokacin da zafin launi iri ɗaya ne, yana ƙayyade ƙimar xy ɗinsa mai daidaitawa da bambanci tsakaninsa da tushen haske na yau da kullun. Girman haƙurin launi, mafi girman bambancin launi. Naúrar wannan haƙurin launi shine SDCM,. Haƙurin Chromatic yana ƙayyade bambanci a cikin launin haske na rukuni na fitilu. Yawancin lokaci ana nuna kewayon haƙurin launi akan jadawalin azaman ellipse maimakon da'ira. Kayan aiki na ƙwararru gabaɗaya suna da duniyoyi masu haɗawa don auna takamaiman bayanai, kuma wasu masana'antun marufi na LED da masana'antun haske suna da kayan aikin ƙwararru masu alaƙa.

Muna da na'urar gwaji tamu a cibiyar tallace-tallace da masana'anta, kowanne samfurin kuma za a gwada kayan aikin farko (gami da COB LED STRIP, NEON FLEX, SMD LED STRIP DA RGB LED STRIP), kuma za a yi amfani da kayan aiki da yawa ne kawai bayan an ci gwajin. Haka kuma muna lulluɓe beads ɗin fitilar da kanmu, waɗanda za a iya sarrafa su sosai a cikin kwandon hasken LED.

Saboda bambancin launin da fararen fitilun LED ke samarwa, ma'auni mai dacewa don bayyana girman bambancin launi a cikin tarin LEDs shine adadin matakan ellipses na SDCM (MacAdam) da LEDs ke faɗuwa a ciki. Idan LEDs ɗin duk sun faɗi cikin SDCM 1 (ko kuma "Makamin ellipse na MacAdam 1"), yawancin mutane ba za su ga wani bambanci a launi ba. Idan bambancin launi ya kasance kamar yadda bambancin chromaticity ya faɗa zuwa yankin da ya ninka girma sau biyu (SDCM 2 ko ellipse na MacAdam 2), za ku fara ganin wasu bambancin launi. ellipse na MacAdam 2 ya fi yankin matakai 3 kyau, da sauransu.
