摘要： A switching circuit system includes a rectification circuit, a transformer, a light-emitting unit, a touch panel including a plurality of touch sensors, and a central processing unit (CPU). The CPU determines that a first user operation is taken place on the touch panel when first and second touch signals from at least two touch sensors have been received within a predetermined time interval, and further determines the track of the touches according to the sequence in which the first and second touch signals were received when the first user operation was determined. The CPU further directs the transformer to control the voltage output to the light-emitting unit according to the determined touch track to control the switching circuit system to execute a first function, and otherwise, a second user operation is determined which executes a second function. A related method is also provided.

摘要： A lamp tube includes a lamp shade, connectors fixed to opposite ends of the lamp shade, and a circuit board received in the lamp shade and electrically connected with the connectors. At least two resilient members protrude from opposite sides of the circuit board. Each resilient member is resiliently deformed and urged into contact with an inner surface of the lamp shade. The deformation of the at least two resilient members is for providing a spring push force to the circuit board, thus causing the circuit board to tightly engage the inner surface of the lamp shade, thereby retaining the circuit board in position inside the lamp shade.

The reference circuit includes a third reference terminal connected to the first reference terminal, and the reference circuit outputs a stable reference voltage via the third reference terminal, to provide the stable reference voltage for the first reference terminal. The impedance regulation circuit is connected to the first reference terminal, to provide equivalent impedance for the first reference terminal. The impedance of the equivalent impedance changes in a way corresponding to changes in the current flowing through the output terminal.
