Maxay yihiinChip-on-Board ("COB") LEDs?
Chip-on-Board ama "COB" waxaa loola jeedaa ku rakibida chip-ka-leedh qaawan oo xiriir toos ah la leh substrate (sida silikoon carbide ama sapphire) si loo soo saaro arrays LED. COB LED-yadu waxay leeyihiin faa'iidooyin dhowr ah oo ku saabsan tignoolajiyada hore ee LED, sida Qalabka Dusha sare leh ("SMD") LEDs ama Xidhmada Dual In-line Package ("DIP") LEDs. Inta badan gaar ahaan, tignoolajiyada COB waxay u oggolaaneysaa cufnaanta baakad aad u sareysa oo ah array LED, ama waxa injineerada iftiinka u tixraacaan sida "cufnaanta lumen" oo la hagaajiyay. Tusaale ahaan, adeegsiga tignoolajiyada COB LED ee 10mm x 10mm oo isku wareeg ah natiijooyinka 38 jeer ka badan LED marka la barbar dhigo tignoolajiyada DIP LED iyo 8.5 jeer ka badan LEDs marka la barbar dhigoSMD LEDfarsamada (eeg jaantuska hoose). Tani waxay keenaysaa xoojinta sare iyo isku-dhafka iftiinka. Beddel ahaan, adeegsiga tignoolajiyada COB LED waxay si weyn u dhimi kartaa raadadka iyo isticmaalka tamarta ee qaabka LED-ka iyadoo la ilaalinayo soosaarka iftiinka si joogto ah. Tusaale ahaan, 500 lumen COB LED array waxay noqon kartaa marar badan oo ka yar oo ay cunaan tamar aad u yar marka loo eego 500 lumen SMD ama DIP LED Array.
