Muri rusange, urumuri rwa LED rushobora kugabanywamo ibice bibiri: umuntu kugiti cyeLED urumuriinkomoko cyangwa LED diode yumucyo uturuka hamwe na résistoriste.Mubisabwa, rimwe na rimwe urumuri rwa LED rwashizweho nkurwego rurimo DC-DC ihindura, kandi ubwo buryo bukomeye ntabwo buri murwego rwibiganiro.Niba urumuri rwa LED rutanga cyangwa module nuburyo butandukanye bwa LED diode ubwayo, uburyo busanzwe bwo gucana ni uguhindura amplitude yaLED yinjiza.Kubwibyo, guhitamo LED ibinyabiziga bigomba kwerekeza kuri ibi biranga.LED yumucyo ikoreshwa cyane nkurwanya hamwe na diode ya LED ihujwe murukurikirane, bityo voltage irahagaze neza.Kubwibyo, abakoresha barashobora gukoresha ubucuruzi ubwo aribwo bwose buhoraho bwo gutanga amashanyarazi kugirango batwareLED amatara.

Uburyo bwiza bwa LED strip dimming igisubizo nugukoresha ibisohoka pulse ubugari bwa modulisiyo ya PWM dimming imikorere kugirango ikemure ibibazo bisanzwe byigihe gito.Ibisohoka bimurika bishingiye kumuzigo wikimenyetso cyerekana ibimenyetso kugirango ugere kumahinduka agabanya kugabanya umucyo.Ibipimo byingenzi muguhitamo amashanyarazi atwara ni ugusuzuma isesengura hamwe ninshuro yo gusohora pulse ubugari bwa PWM.Ubushobozi buke bwo gucana bugomba kuba munsi ya 0.1% kugirango ugere kuri 8-biti yo gucana kugirango uhuze na LED yumucyo wuzuye.Ibisohoka bya pulse ubugari bwa modulisiyo ya PWM igomba kuba ndende ishoboka kugirango hirindwe ibibazo biturika, Nkuko bigaragara mubitabo byubushakashatsi bwa tekiniki bijyanye, birasabwa kugira inshuro byibuze hejuru ya 1.25kHz kugirango ugabanye imyuka igaragara kumaso yumuntu.
