Abstract

The present invention provides a RF wireless remote-control brightness-adjustable energy-saving lamp, which comprises 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 pulse-to-DC-voltage-level output circuit is used to convert the PWM signal into a DC voltage level. A VCO circuit connected to a starter power source circuit and a lamp tube lighting driving circuit is also provided. The lamp tube lighting driving circuit is connected to a lamp tube. The VCO circuit is used to drive the lamp tube lighting driving circuit according to the DC voltage level for adjusting the luminescent brightness of the lamp tube. 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. The present invention has the advantages of remotely adjusting the brightness of a lamp and turning on and off a lamp.
