Menene binning launi da SDMC?

Haƙurin launi: ra'ayi ne mai alaƙa da zafin launi. Kodak ne ya gabatar da wannan ra'ayi a cikin masana'antar, Birtaniyya ita ce Madaidaicin Bambancin Launi, wanda ake kira SDCM. Bambanci ne tsakanin ƙididdigan ƙima na kwamfuta da madaidaicin ƙimar tushen hasken manufa. Wato, haƙurin launi yana da ƙayyadaddun nuni ga tushen hasken da aka yi niyya.

Kayan aikin photochromic yana nazarin kewayon zafin launi na tushen hasken da aka auna, sannan ya ƙayyade madaidaicin ƙimar zafin launi.

Naúrar wannan haƙurin launi shine SDCM,. Haƙuri na chromatic yana ƙayyade bambanci a cikin launi mai haske na batch na fitilu. Ana nuna kewayon haƙurin launi akan jadawali azaman ellipse maimakon da'irar. Kayan aiki na ƙwararru na gabaɗaya suna da haɗin kai don auna takamaiman bayanai, kuma wasu masana'antun marufi na LED da masana'antar hasken wuta suna da alaƙa da kayan aikin ƙwararru.

Muna da namu na'urar gwajin a cibiyar tallace-tallace da masana'anta, kowane samfurin da na farko yanki na samarwa (ciki har da COB LED STRIP, NEON FLEX, SMD LED STRIP DA RGB LED STRIP) za a gwada, da kuma taro samar za a yi kawai bayan wucewa. The test.Muna kuma encapsulate da fitila beads da kanmu, wanda za a iya da kyau sarrafa bin na LED tsiri haske.

Saboda bambancin yanayin launi da aka samar ta hanyar farin haske LEDs, ma'auni mai dacewa don bayyana girman bambancin launi a cikin batch na LED shine adadin SDCM (MacAdam) ellipses matakan da LEDs suka fada cikin. Idan LEDs duk sun faɗi cikin 1 SDCM (ko "MacAdam ellipse 1-mataki"), yawancin mutane ba za su ga wani bambanci a launi ba. Idan bambancin launi ya kasance irin wannan bambancin a cikin chromaticity ya shimfiɗa zuwa yanki mai girma sau biyu (2 SDCM ko MacAdam ellipse mai mataki 2), za ku fara ganin wasu bambancin launi. MacAdam ellipse 2-mataki ya fi yankin mataki 3, da sauransu.

Duk da haka, akwai abubuwa da yawa da suka shafi haƙurin launi, kamar dalilan da ke haifar da guntu na LED, dalilin da yasa rabon foda na phosphor, dalilin canjin motsi na yanzu, da tsarin fitilar zai kuma shafi zafin launi.
