LED nuni na'ura ce da ke amfani da diodes masu haske (LEDs) a matsayin abubuwa masu fitar da haske don nuna hotuna, bidiyo, rayarwa da sauran bayanai ta hanyar lantarki. LED nuni yana da abũbuwan amfãni daga high haske, low ikon amfani, tsawon rai, m Viewing kwana, da dai sauransu, kuma ana amfani da ko'ina a cikin gida da waje talla, sufuri, wasanni, al'adu nisha da sauran filayen. Don tabbatar da tasirin nuni da ingantaccen tanadin makamashi na nunin nunin LED, ya zama dole a lissafta yankin allo da haske a hankali.
1. Hanyar ƙididdige yankin allo na allon nunin LED
Wurin allo na nunin LED yana nufin girman girman wurin nuninsa, yawanci a cikin murabba'in mita. Don ƙididdige yankin allo na nunin LED, ana buƙatar sanin sigogi masu zuwa:
1. Tazarar dige-dige: tazara ta tsakiya tsakanin kowane pixel da pixels maƙwabta, yawanci a cikin millimeters. Karamin ɗigon ɗigo, mafi girman girman pixel, mafi girman ƙuduri, ƙarar tasirin nuni, amma mafi girman farashi. Gabaɗaya ana ƙididdige farar ɗigo bisa ga ainihin yanayin aikace-aikacen da nisan kallo.
2. Girman Module: kowane module ya ƙunshi pixels da yawa, wanda shine ainihin naúrar nunin LED. Girman ƙirar yana ƙayyade ta adadin pixels a kwance da na tsaye, yawanci a santimita. Misali, tsarin P10 yana nufin cewa kowane module yana da pixels 10 a kwance da kuma a tsaye, wato 32 × 16 = 512 pixels, girman module ɗin kuma shine 32 × 16 × 0.1 = 51.2 square centimeters.
3. Girma na allo: Dukkanin Nunin LED shine an ƙaddara shi da yawa, kuma girmanta an ƙaddara shi da adadin kayan kwance da na tsaye, yawanci a cikin mites. Misali, allon cikakken launi na P10 mai tsayin mita 5 da tsayin mita 3 yana nufin cewa akwai 50/0.32=156 modules a cikin madaidaiciyar hanya da 30/0.16=187 modules a tsaye.
2. Hanyar ƙididdige haske na nunin LED
Hasken nunin LED yana nufin tsananin hasken da yake fitarwa a ƙarƙashin wasu yanayi, yawanci a cikin candela kowace murabba'in mita (cd/m2). Mafi girman haske, mafi ƙarfin haske, mafi girma da bambanci, kuma mafi ƙarfin ikon hana tsangwama. Ana ƙayyade haske gabaɗaya bisa ga ainihin yanayin aikace-aikacen da kusurwar kallo.
1. Hasken fitilar LED guda ɗaya: ƙarfin hasken da kowane fitilar LED mai launi ke fitarwa, yawanci a millicandela (mcd). Hasken fitilar LED guda ɗaya yana samuwa ne ta hanyar kayansa, tsarinsa, halin yanzu da sauran abubuwa, kuma hasken fitulun LED masu launuka daban-daban shima daban ne. Misali, hasken jajayen fitilun LED shine gabaɗaya 800-1000mcd, hasken koren LED fitilu gabaɗaya 2000-3000mcd, kuma hasken shuɗi na LED fitilu gabaɗaya 300-500mcd.
2. Hasken kowane pixel: Kowane pixel yana kunshe da fitilun LED masu launuka daban-daban, kuma ƙarfin hasken da yake fitarwa shine jimlar hasken kowane launi LED haske, yawanci a candela (cd) a matsayin naúrar. Hasken kowane pixel yana samuwa ne ta hanyar abun da ke ciki da girmansa, kuma hasken kowane pixel na nau'ikan nunin LED daban-daban ma daban. Misali, kowane pixel na allon cikakken launi na P16 ya ƙunshi 2 ja, 1 kore, da fitilun LED shuɗi 1. Idan ana amfani da 800mcd ja, 2300mcd kore, da 350mcd blue LED fitulun, hasken kowane pixel shine (800×2 +2300+350)=4250mcd=4.25cd.
3. Gabaɗayan haske na allon: ƙarfin hasken da ke fitar da dukkan nunin LED shine jimlar hasken duk pixels da aka raba ta wurin allo, yawanci a candela kowace murabba'in mita (cd/m2) a matsayin naúrar. Gabaɗayan haske na allon yana ƙaddara ta ƙudurinsa, yanayin dubawa, tuƙi na yanzu da sauran abubuwan. Daban-daban na nunin nunin LED suna da haske gaba ɗaya. Misali, ƙuduri kowane murabba'i na allon cikakken launi na P16 shine 3906 DOT, kuma hanyar dubawa shine 1/4 scanning, don haka mafi girman girman haske shine (4.25 × 3906/4) = 4138.625 cd/m2.
3. Takaitawa
Wannan labarin yana gabatar da hanyar ƙididdige yanki da haske na allon nuni na LED, kuma yana ba da ma'auni da misalai masu dacewa. Ta hanyar waɗannan hanyoyin, ana iya zaɓar sigogin nunin LED masu dacewa bisa ga ainihin buƙatu da yanayi, kuma ana iya inganta tasirin nuni da ingantaccen ceton kuzari. Tabbas, a cikin aikace-aikace masu amfani, wasu dalilai suna buƙatar la'akari da su, irin su tasirin hasken yanayi, zafin jiki da zafi, zafi mai zafi, da dai sauransu akan aiki da rayuwar nunin LED.
Nunin LED kyakkyawan katin kasuwanci ne a cikin al'ummar yau. Ba zai iya nuna bayanai kawai ba, har ma da isar da al'adu, ƙirƙirar yanayi da haɓaka hoto. Koyaya, don samun matsakaicin sakamako na nunin LED, ya zama dole don ƙware wasu hanyoyin ƙididdiga na asali, ƙira mai dacewa da zaɓi yankin allo da haske. Ta wannan hanyar kawai za mu iya tabbatar da bayyanannun nuni, ceton makamashi, kare muhalli, dorewa da tattalin arziki.
