A1

A method for brightness level adjustment of an LED (light emitting diode) lighting system with a plurality of LED lighting devices (1) includes each LED lighting device (1) receiving brightness level adjustment information (5001), wherein the brightness level adjustment information (5001) includes a group-control brightness level adjustment value (5002) for adjustment brightness level of the lighting system and an individual-control brightness level adjustment value (5003, 5004, 5005) for adjusting brightness level of the LED lighting device (1). The method further includes the LED lighting device (1) performing calculation to obtain brightness level value of the LED lighting device (1) based on the group-control brightness level adjustment value (5002) and the individual-control brightness level adjustment value (5003, 5004, 5005). The brightness level value is configured to indicate a desired brightness level of the LED lighting device (1). The method also includes the LED lighting device (1) adjusting brightness corresponding to the brightness level value.
