An RF wireless remote-control brightness-adjustable energy-saving lamp is provided which includes a brightness-adjustable energy-saving lamp and a RF remote-control module. The brightness-adjustable energy-saving lamp has a RF wireless receiver circuit therein to receive a remote-control signal and transmit it to a CPU. The CPU is used to discriminate the remote-control signal, convert it into a PWM signal, and output the PWM signal to a pulse-to-DC-voltage-level output circuit. The RF remote-control module can learn the internal code of the brightness-adjustable energy-saving lamp and transmit out a remote-control signal to the brightness-adjustable energy-saving lamp through pressing a key.
