Marka hore, waa lagama maarmaan in la yeesho faham aasaasi ah oo ku saabsan aaladda dusha sare ee dusha sare (SMD) LEDs. Waxay shaki la'aan yihiin LED-yada ugu badan ee la isticmaalo hadda. Kala duwanaanshahooda awgeed, chips LED waxay si adag ugu dheggan yihiin looxyada wareegga daabacan oo si ballaaran loo isticmaalo xitaa nalalka ogeysiiska casriga ah. Mid ka mid ah sifooyinka ugu caansan ee chips LED SMD waa tirada isku xirka iyo diodes.
Qalabka LED-ka ee SMD, waxaa jiri kara in ka badan laba xiriir. Ilaa saddex diode oo leh wareegyo madax-bannaan ayaa laga heli karaa hal jajab. Wareeg kasta wuxuu leeyahay anode iyo cathode, taasoo keentay in 2, 4, ama 6 isku xirka chip-ka.
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 chip-ka noocan oo kale ah wuxuu leeyahay cathode iyo anode, taasoo keentay 2, 4, ama 6 xiriiriye. Chips-yada COB waxay badanaa leeyihiin sagaal ama in ka badan diode. Intaa waxaa dheer, chips COB waxay leeyihiin laba xiriir iyo hal wareeg iyadoo aan loo eegin tirada diodes. Naqshadaynta wareeggan fudud awgeed, nalalka COB LED waxay leeyihiin muuqaal u eg guddi, halka nalalka LED-ka ee SMD ay u eg yihiin koox nalal yar yar.
Diodes casaan, cagaar, iyo buluug ah waxay ku jiri karaan chip LED SMD. Adiga oo kala duwanaya heerarka wax soo saarka ee saddexda diode, waxaad soo saari kartaa midab kasta. Si kastaba ha ahaatee, nalka COB LED, si kastaba ha ahaatee, waxaa jira laba xiriir oo kaliya iyo wareeg. Suurtagal maaha in la sameeyo nal ama nalka midab beddela. Hagaajinta kanaalka badan ayaa loo baahan yahay si loo helo saameyn beddeleysa midabka. Sidaa darteed, nalalka COB LED waxay si fiican ugu shaqeeyaan codsiyada u baahan hal midab halkii midabyo badan.
Kala duwanaanshaha dhalaalka ee chips SMD ayaa si fiican loo yaqaan inay yihiin 50 ilaa 100 lumens per watt. COB waxay caan ku tahay waxtarkeeda kulaylka sare iyo lumen per watt ratio. Haddii chip COB uu leeyahay ugu yaraan 80 lumens per watt, wuxuu sii dayn karaa lumen badan oo koronto yar leh. Waxaa loo isticmaali karaa noocyo badan oo kala duwan oo nalalka ah iyo aaladaha, sida flash taleefoonka gacanta ama kamaradaha dhibic-iyo-tooska ah.
Intaa waxaa dheer, chips-yada SMD LED waxay u baahan yihiin ilo tamar dibadda ah oo yar, halka COB LED chips ay u baahan yihiin ilo tamar dibadeed oo weyn.
