Both COB and SMD LEDs have high luminous efficiency and high durability. Both have an extremely low failure rate.
COB LEDs are being used more and more in lighting applications with their simpler structures, lower light losses and high lumen output in a small area.
CREE, Seoul Semiconductor, Citizen, Bridgelux and Evercore are the leading COB LED manufacturers of the world. Manufacturers such as Nichia, Osram, Lumileds, LG Innotek and Edison also stand out in SMD LED technology.
Both SMD and COB technology have wide application areas. One of the two technologies should be chosen according to the application needs.
