COB (Chip-on-Board) and SMD (Surface-Mount Device) are two different types of LED (Light Emitting Diode) technologies used in LED strip lighting. The main differences between COB and SMD LED strips are:
Construction: COB LEDs consist of multiple LED chips mounted directly on a circuit board, whereas SMD LEDs consist of individual LED chips mounted on a surface mount board.
Size: COB LEDs are typically larger in size compared to SMD LEDs. The size of the COB chip determines the size of the LED strip, whereas the size of the SMD chip can vary, allowing for more flexibility in designing different sizes of LED strips.
Brightness: COB LEDs typically provide a higher lumen output (brightness) compared to SMD LEDs. This is because the COB technology allows for a higher density of LED chips, which results in a brighter light output.
Heat dissipation: COB LED strips tend to generate more heat compared to SMD LED strips. This is because of the higher density of LED chips in COB LED strips, which can lead to more heat buildup. As a result, COB LED strips may require additional heat sinks or cooling systems to prevent overheating.
Cost: COB LED strips are generally more expensive compared to SMD LED strips due to their higher brightness output and construction complexity.
Overall, COB LED strips are suitable for applications that require high brightness levels, while SMD LED strips are more suitable for applications where size, flexibility, and cost are important factors.
