COB LED and SMD LED are two different types of LED technologies. Here are some differences between them:
Size: COB LEDs are larger in size compared to SMD LEDs. A single COB LED can be made up of multiple LED chips, while an SMD LED is a single LED chip.
Brightness: COB LEDs are generally brighter than SMD LEDs. This is because COB LEDs have a higher power density and can produce more lumens per watt.
Heat Dissipation: COB LEDs have better heat dissipation compared to SMD LEDs. This is because the COB LED chips are mounted directly onto a substrate, which helps to spread the heat more evenly across the module.
Energy Efficiency: COB LEDs are generally more energy-efficient than SMD LEDs. This is because COB LEDs can produce more light using less power.
Cost: COB LEDs are generally more expensive compared to SMD LEDs. This is because COB LEDs require more materials to manufacture and are larger in size.
In summary, COB LEDs are generally brighter, more energy-efficient, and have better heat dissipation compared to SMD LEDs. However, they are also more expensive and larger in size.
