COB stands for Chip on Board, meaning the LED diodes are built directly into the printed circuit board. A phospur coating is then applied over the LED chips and acts as built-in diffuser. The main advantage of this technology is that there is no visible spotting, even when used in more shallow LED profiles and spaces, this ensures the finished installation will present a seamless uninterrupted finish.
This makes our COB Continuous LED Strip Light perfect for high-end professional and commercial installations. The high build quality and components will assure long lasting performance and reliability.
COB LEDs are mounted directly into the circuit board with a cover of phospur over the top acting as a ‘diffuser’ enabling a seamless finish when illuminated. Being directly mounted to the circuit board means there is room for more LEDs to be mounted. Our COB LED strip lights typically achieve between 320-544 LEDs per metre.
Compare this to current traditional LED strip light and the use of SMD (Surface Mounted Diode) technology, where the LED chips are mounted and secured on top of the circuit board. This manufacturing process typically achieves a maximum of 240 LEDs per metre.
The SMD version is much more likely to cause spotting and dark spots due to the spacing of the chips on the LED strip light. This spotting effect can be emphasised when the strip light is installed into a shallow LED profile with a semi clear, or transparent diffuser.
COB LED strip light on the other hand produces no spotting and can even be used without an LED profile.
