Si loo bilaabo, waa lagama maarmaan in la yeesho faham aasaasi ah oo ku saabsan aaladaha ku rakiban dusha sare (SMD) LEDs. Waxay shaki la'aan yihiin LED-yada loo isticmaalo inta badan hadda. Kala duwanaanshaheeda awgeed, xitaa iftiinka ogeysiiska casriga ah, chip LED wuxuu si adag ugu dheggan yahay guddiga wareegga daabacan oo si ballaaran ayaa loo shaqeeyaa. Mid ka mid ah sifooyinka ugu caansan ee chips LED SMD waa tirada isku xirka iyo diodes.
SMD chips LED, waxaa suurtagal ah in la yeesho wax ka badan laba xiriiriye. Ilaa saddex diode oo leh wareegyo gaar ah ayaa laga heli karaa hal jajab. Wareeg kastaa wuxuu lahaan lahaa anode iyo cathode, taasoo keentay in 2, 4, ama 6 isku xirka chip.
Farqiga u dhexeeya COB LEDs iyo SMD LEDs.
Hal chip SMD LED, waxaa jiri kara ilaa saddex diode, mid kastaa wuxuu leeyahay wareeggiisa. Wareeg kasta oo ka mid ah jajabka noocaan ah wuxuu leeyahay hal cathode iyo hal anode, taasoo keentay 2, 4, ama 6 xiriiriye. Chips-yada COB waxay caadi ahaan leeyihiin sagaal diode ama ka badan. Intaa waxaa dheer, chips COB waxay leeyihiin laba xiriiriye iyo hal wareeg iyadoo aan loo eegin tirada diodes-ka. Naqshadaynta wareeggan fudud awgeed, nalalka COB LED waxay leeyihiin muuqaal u eg guddi, halka nalalka LED-ka ee SMD ay u muuqan doonaan inay yihiin ururinta nalal yaryar.
Diode casaan, cagaar, iyo buluug ah ayaa ku jiri kara chip-ka LED-ka ee SMD. Beddelista heerka wax soo saarka ee saddexda diode, waxaad soo saari kartaa midab kasta. Nalalka COB LED, si kastaba ha ahaatee, waxaa jira laba xiriir oo keliya iyo hal wareeg. Suuragal maaha in loo isticmaalo in lagu sameeyo nalal ama nalal midab beddela. Dib u habeyn badan oo kanaalka ayaa loo baahan yahay si loo helo saameynta isbeddelka midabka. Natiijo ahaan, nalalka COB LED waxay si fiican ugu shaqeeyaan codsiyada u baahan hal midab laakiin maaha midabyo badan.
Chips-yada SMD waxay leeyihiin dhalaal caan ah oo u dhexeeya 50 ilaa 100 lumens per watt. Waxtarka kulaylka weyn iyo lumens per watt ratio ee COB waa la yaqaan. Chips-yada COB waxay sii dayn karaan lumen badan oo koronto yar leh haddii ay haystaan ugu yaraan 80 lumens per watt. Waxaa laga heli karaa noocyo badan oo kala duwan oo nalalka ah iyo aaladaha, sida flash-ka talefankaaga ama kamaradaha-fiiqista.
Ilaha tamarta dibadeed ee yar ayaa looga baahan yahay chips-ka SMD LED, halka ilo tamar dibadeed oo weyn looga baahan yahay chips-yada COB LED.
