Itara ryo Kumanika Tangent ni itara ryo kumanika ryagenewe imyubakire y'ibyumba. Imiterere yaryo ishingiye ku miterere ya jewometrike ikozwe mu mizunguruko (circles) n'imirongo ibikoraho (tangents). Buri gishushanyo gishobora guhindurwa hakurikijwe imiterere y'ahantu cyangwa gikaboneza hakurikijwe ibyo ukoresha ashaka, bityo ingano zaryo zikaba zitandukana bitewe na buri mushinga. Umubiri waryo ukorwa mu cyuma cya aluminium cyakozwe mu buryo bw'ubukanishi (extruded), gikagoreka kigahabwa imiterere yatoranyijwe. Itara rya LED rishyirwa mo muri iyo profil. Igice cyo hejuru n'igikoresho gisakaza urumuri (diffuser) bikoreshwa lazeri mu gucibwa, hanyuma bigashyirwa ku mubiri w'itara. Intego ni ugutanga umuti w'urumuri wagenewe buri cyumba ku buryo bwihariye.
