A light source module includes a circuit board, a light source electrically coupled to the circuit board including a first light emerging face, a light guide plate close to the light source and including an light incident face, a reflective piece located on one side of the light guide plate, a diffusion plate located on another side of the light guide plate, a frame used to fix the circuit board, the light guide plate, the reflective piece and the diffusion plate. The light incident face and the light emerging face cooperatively forming an angle. Light from the light source is guided by the light guide plate and reflected by the reflective piece and diffused by the diffusion plate.

A power adapter includes a regulation device, which includes a division circuit, a reference circuit, and an impedance regulation circuit. The division circuit includes a first reference terminal and a second reference terminal. The second reference terminal is connected to an output terminal of the regulation device. 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.

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.
