SDCM ni iki?

Kwihanganira amabara SDCM bivuga itandukaniro ryamabara hagati yibiti bitandukanye bitangwa numucyo umwe wamabara yumucyo murwego rwamabara yabonwa nijisho ryumuntu, ubusanzwe bigaragazwa numubare wimibare, bizwi kandi gutandukanya ibara. Kwihanganira amabara SDCM nimwe mubipimo byingenzi byo gupima ibara ryibicuruzwa bya LED bimurika. Muri LED yamurika, ingano yihanganira ibara SDCM igira ingaruka itaziguye kumiterere no gutuza kwingaruka.

Uburyo bwo kubara bwo kwihanganira amabara SDCM nuguhindura itandukaniro ryumurongo hagati yumucyo wapimwe nisoko isanzwe yumucyo kubiciro bya SDCM ukurikije igishushanyo mbonera cya CIE 1931. Gutoya SDCM agaciro, nibyiza amabara ahoraho, kandi nini itandukaniro ryibara. Mubihe bisanzwe, ibicuruzwa bifite agaciro ka SDCM muri 3 bifatwa nkibicuruzwa bifite ibara ryiza rihoraho, mugihe ibirenze 3 bigomba kurushaho kunozwa.

Muri LED yamurika porogaramu, ibara rihoraho rifite ingaruka zikomeye kumutekano no guhumurizwa kwingaruka zumucyo. Niba ibara ridahwitse ryibicuruzwa bimurika LED ari bibi, ibara ryibice bitandukanye mumwanya umwe bizaba bitandukanye cyane, bigira ingaruka kumukoresha. Mugihe kimwe, ibicuruzwa bifite ibara ridahwitse bishobora nanone gutera ibibazo nkumunaniro ugaragara no kugoreka amabara.

Kugirango tunoze ibara rihoraho ryibicuruzwa bimurika LED, birakenewe gutangirira kubintu byinshi. Mbere ya byose, ubwiza bwa chip ya LED bugomba kugenzurwa cyane kugirango harebwe ibara rya chip ya LED. Icya kabiri, kugenzura ubuziranenge burakenewe kubicuruzwa bimurika LED kugirango umenye neza ko ibara rya buri gicuruzwa ari kimwe. Hanyuma, urumuri rwa LED rukeneye gukemurwa no gutezimbere kugirango ibara rihuze hagati yamasoko atandukanye.

Muri make, kwihanganira amabara SDCM ni kimwe mu bipimo byingenzi bipima ibara ry’ibicuruzwa bitanga amatara ya LED, bigira uruhare runini mu kuzamura ubwiza n’umutekano by’ingaruka zo kumurika ibicuruzwa bya LED. Kugirango tunonosore ibara ryibicuruzwa byamatara ya LED, birakenewe ko duhera mubice byinshi kugirango tumenye neza ko ubwiza bwa chip ya LED, ubwiza bwibicuruzwa bimurika LED hamwe no gucana amatara ya LED yujuje ubuziranenge.
