A COB LED strip light is a linear chip-on-board LED array fabricated on a flexible printed circuit board. Chip-on-board (COB) technology enables creation of a homogeneous light emitting surface (LES) that is impossible with SMD technology. The introduction of COB technology to flexible linear lighting applications creates yet another innovation. COB LED strips are capable of delivering a continuous run of lighting without any visible individual light points. The ability to provide truly seamless illumination without shadows makes the COB light strip a fantastic product for use in architectural and decorative lighting applications.
COB LED strip lights are also known as FOB or FCOB LED strips. Most people would associate the letter “F” in the abbreviations with the word “flexible”. It sounds pretty reasonable from an end-user perspective. However, technically the names were derived from the flip chip-on-board (FCOB) technology, which is the driving force behind the innovation. In a conventional COB package, an array of LED dies (chips) are wire-bonded with aluminum or gold wires and die-bonded on a metal-core printed circuit board (MCPCB) or ceramic substrate with silver-filled epoxy. The die matrix is then covered with a phosphor silicone mixture to enhance light uniformity, provide wavelength conversion, and to shield the chip array from the environment.
