Chidziwitso cha LED Gawo 2: Kodi ma LED ali ndi mitundu yanji?

White LED

Zosiyanitsa zingapo zimapangidwa panthawi yopanga magetsi osankhidwa a LED.Madera a chromatic otchedwa 'bin' ndi mizere yopingasa motsatira mzere wa BBL.Kufanana kwamitundu kumatengera luso la wopanga komanso miyezo yabwino.Kusankhidwa kwakukulu kumatanthauza khalidwe lapamwamba, komanso mtengo wapamwamba.

MacAdam Ellipses

Onani malo omwe ali pa chithunzi cha chromaticity chomwe chili ndi mitundu yonse yosazindikirika, ndi diso la munthu, kuchokera pamtundu wapakati pa ellipse.Mzere wa ellipse umayimira kusiyana kowoneka bwino kwa chromaticity.MacAdam akuwonetsa kusiyana pakati pa magwero awiri a kuwala kudzera mu ellipses, omwe amafotokozedwa kuti ali ndi 'masitepe' omwe amawonetsa kupotozedwa kwamtundu.M'mapulogalamu omwe kuwala kumawonekera, chodabwitsachi chiyenera kuganiziridwa chifukwa ellipse ya 3-step ili ndi kusiyana kwa mtundu wochepa kusiyana ndi 5-step.

Ma LED amitundu

Chojambula cha CIE chromatic chimatengera mawonekedwe achilengedwe a diso la munthu kuti awone mitundu poyigawa m'zigawo zitatu zofunika kwambiri za chromatic (njira yamitundu itatu): yofiira, yabuluu ndi yobiriwira, yomwe ili pamwamba pa chithunzicho.Chojambula cha CIE chromatic chikhoza kupezeka powerengera x ndi y pamtundu uliwonse.Mitundu ya sipekitiramu (kapena mitundu yoyera) imatha kupezeka pamapindikira, pomwe mitundu yamkati mwachithunzicho ndi mitundu yeniyeni.Tiyenera kukumbukira kuti mtundu woyera (ndi mitundu ina m'chigawo chapakati - mitundu ya achromatic kapena mithunzi ya imvi) si mitundu yoyera, ndipo sungagwirizane ndi kutalika kwake.
