    Tips: Can constant current LED drivers work with multiple LEDs?

    Yes, constant current LED drivers can work with multiple LEDs. When connecting multiple LEDs to a constant current driver, it's important to consider the configuration of the LEDs—whether they are connected in series or parallel.

    In a series configuration, the LEDs are connected end-to-end. The total forward voltage of the series is the sum of the forward voltages of each LED. Constant current drivers are suitable for series configurations because they can provide a consistent current to the entire series, ensuring each LED receives the required current.

    In a parallel configuration, the LEDs are connected side by side, each with its own branch from the driver. For parallel connections, it's essential to ensure that the driver can handle the combined forward current of all parallel branches. The constant current driver distributes the specified current to each parallel branch, maintaining the individual current requirements of each LED.

    Whether in series or parallel, the total forward voltage and current requirements of the connected LEDs should be within the specifications of the constant current driver. This ensures optimal performance and longevity of both the LEDs and the driver. Always refer to the manufacturer's guidelines for proper configuration and wiring.
