Aasaaska aasaasiga ah ee Voltage
Voltage of strips LED waxay ku xiran tahay laba arrimood:
Voltage-ka LED-yada, Qaybahooda, iyo Bixinta Korontada
Markaad go'aaminayso danabka nalalka laydhka LED, waxaad u baahan tahay inaad tixgeliso saddex arrimood. Kuwani waa sidan soo socota-
- Voltage LED
LEDs-yada loo isticmaalo nalalka xariijinta waxay leeyihiin shuruud danab shaqsiyeed. Korontadan waxaa badanaa loo yaqaan 'Forward Voltage' ama 'VF'. Waa danabka ugu yar ee LED-ku u baahan yahay inuu iftiimiyo. Baahida danabku way kala duwan tahay nooca iyo midabka LED-ka. Tusaale ahaan, LED-ka cad wuxuu badiyaa u baahan yahay qiyaastii 3 ilaa 3.4 volts. Midabada kale ee iftiinka ayay tani ku kala duwanaan kartaa. Shaxda hoose waxay ku tusinaysaa qiyaasta korantada hore ee LED-yada midabyo kala duwan

Xarigga LED-ku waxay ka kooban yihiin qaybo kala duwan. Kuwaas waxaa ka mid ah- resistors, diodes, iyo capacitors. Mid kasta oo ka mid ah qaybahan 'voltage' waa in uu la mid yahay korantada LED-ka. Haddii danabku uusan isqabin, waxay dhaawici kartaa qaybaha ama waxay keeni kartaa cillad.
- Voltage Supply System
Korontada sahayda korantada waxaa loo yaqaan 'volt-ka wax-soo-saarka' ama 'qalabka sahayda.' Waa danab dibadda ah oo la siiyo qalabka. Maaddaama nalalka laydhka LED-ku ay yihiin kuwo korantada-xasaasi ah, waxaa lama huraan ah in la hubiyo in danabka LED-yada iyo qaybaha ay ka kooban yihiin ay la siman yihiin danabka isha korontada. Tusaale ahaan- haddii aad leedahay xariijin 12-volt LED ah, waa inaad isticmaashaa koronto 12-volt ah. Haddii aad isticmaasho danab sare ama ka hooseeya, nalalka laydhka LED si fiican uma shaqayn doonaan.
Habaynta LED-yada
Nalalka LED-yada ee laydhka xariijinta LED-ka waxaa loo habayn karaa laba nooc oo qaabeyn ah- taxane iyo isbarbar socda. Kuwan ayaa looga hadlayaa hoos-

Caadi ahaan, nalalka laydhka LED-ka ayaa loo tixgaliyaa inay yihiin nalka danab yar. Laakiin kala duwanaanshiyaha tamarta sare ayaa sidoo kale la heli karaa. Qiimaynta danab ee strips LED waa sida soo socota:
Xarigga LED-ka Korantada Hoose
Inta badan nalalka laydhka LED waxay badanaa ku yimaadaan 12V ama 24V. Marka hore waxay ku habboon tahay nalka gudaha; Waxa kale oo aad ka heli doontaa iyaga oo ku jira iftiinka baabuurta- Tilmaamaha Dhameystiran ee 12 Volt nalalka LED ee RVs. Dhanka kale, 24V strips LED ayaa inta badan loo isticmaalaa nalalka dibadda ama ganacsiga. Marka la barbardhigo labada xariijin, xariijinta 24V LED ayaa ka waxtar badan tan 12V. Si aad u ogaato sida loo doorto qiimaynta danab ee strips LED, raac tilmaantan- Sida loo doorto Voltage of Strip LED? 12V ama 24V? Si kastaba ha ahaatee, xariijimaha LED-ka hooseeya ee 5V ayaa sidoo kale la heli karaa. Inta badan nalalka xariijinta laydhka ee awoodda USB waxay badanaa leeyihiin qiimeyn 5V ah. Hoosta, waxaan ku darayaa shaxda isbarbardhigga degdega ah ee strips LED-ka hooseeya-

Sidee Loo Yareeyaa Dhibicda Xadhkaha LED-ka?
Iftiinka iyo guud ahaan soosaarka nalka ayaa si xun u saameeyay hoos u dhaca danabka. Waa kuwan dariiqooyinka soo socda oo aad ku yareeyn karto hoos u dhaca korantada LED-ka ee hababka soo socda:
1. Isticmaal Xariijimaha LED-ka ee Korantada Sare
Xariijimaha LED-ka ee korantada-sare aad ayey ugu nugul yihiin hoos u dhaca danab. Haddii aad la kulanto arrimaha hoos u dhaca korantada adoo isticmaalaya 12V ama 24V LED strips, waxaan kuu soo jeedinayaa inaad doorato xariijinta korantada sare ee LED. Waxay noqon kartaa 48Vdc ama 36Vdc strip LED ama 110Vac, 120Vac (ama ka sareeya) oo ku habboon ujeedadaada iftiinka. Laakin wax kasta oo aad doorato, hubi in danabka xariifka LED-ku uu ku habboon yahay korantada isha korontada.
2. Yaree Dhererka Xarigga LED-ka
Hoos-u-dhaca danab iyo caabbinta socodka hadda waxay kordhisaa dhererka korodhka.
Dhererka ⬆ Voltage ⬆ Hoos u dhaca Korantada ⬇
Taasi waa sababta gaabinaysa dhererka xariijinta LED waxay yaraynaysaa hoos u dhaca danabka. Si aad wax badan uga ogaato dhererka xargaha LED-ka iyo dantooda, hubi tan- Waa maxay Nalalka Xadhkaha LED-ka ee ugu Dheer?
3. Siligyada Isbarbarya ee Xadhkaha Badan
Markaad ku xidho fiilooyin badan oo LED ah si aad dhererka u kordhiso, waxay keenaysaa hoos u dhac danab ah. Natiijo ahaan, dhalaalka xariijinta LED-ku wuxuu bilaabaa inuu si tartiib tartiib ah u dhinto marka dhererku kordho. Si looga fogaado arrimahan oo kale, ku xidh fiilooyinka is-bar-barya ee ka imanaya isha korantada iyo xariijin kasta oo cusub oo LED ah. Tani waxay yaraynaysaa hoos u dhaca danab.
4. Isticmaal PCB ka dhumuc weyn oo ballaadhan
Dhammaan qaybaha fiilada LED-ku waxay ku habaysan yihiin sabuuradda wareegga daabacan ama PCB. Waxa kale oo ku jira iska caabin. Marka dhererku kordho, caabbinta ayaa sidoo kale kordhisa, taas oo keenta hoos u dhaca danab. Laakin waxaad yareyn kartaa hoos u dhaca danab adigoo isticmaalaya PCB ka dhumuc weyn oo ka ballaaran.
Ma tahay inaad si sax ah u keento Voltage-ka lagu cayimay?
Nalalka LED-yadu waa kuwa xasaasi ah. Taasi waa sababta ay muhiim u tahay in la siiyo koronto sax ah nalalka laydhka LED-ka si loo helo waxqabadka ugu fiican. Si kastaba ha ahaatee, waxaa jira kala duwanaansho dulqaad ah oo LED-yadu ay qaadan karaan danab. Haddii danabka la keenay uu dhaafo heerka dulqaadka, qalabku wuu dhaawacmi doonaa.
Korantada shaqaynaysa ee LED-yada waxa loo yaqaan danab hore ama VF. Tusaale ahaan, haddii VF ee LED uu yahay 3.2 volts oo leh dulqaad ± 0.1 volts. Tani waxay muujinaysaa in laydhka laydhka ee LED uu si sax ah u shaqayn karo inta u dhaxaysa 3.1 volts ilaa 3.3 volts. Haddii danabka la keenay uu ka bato tan, waxay dhaawici doontaa LED-ga. Taasi waa sababta ay u fiican tahay in la bixiyo tamarta sida saxda ah ee qeexitaanka.
