Hello Gaurav,

COB = Chip-on-Board
- Typical applications are mainly light spots, round ceiling lights, retrofits, etc.
- low thermal resistance and high efficiency
- high uniformity
- Longer service life

Discrete LED components
- mounted on a common MCPCB (Metal Core PCB) do not produce a homogeneous emission, but optical hot spots, for example.
- high thermal resistance
- Application area with high-power LEDs or PLCC LEDs, with which the light requirements can be realized more cost-effectively.
