Abstract
An illumination dummy module is adapted for covering and protecting a card slot and includes a circuit board, a power pin, a clock pin, a data pin, at least one light source, a power converter, and a drive circuit. The circuit board includes an insertion part for inserting into the card slot. The power pin, the clock pin and the data pin are disposed to the insertion part, and the light source is disposed on the circuit board. The power converter receives input power from the card slot via the power pin, and converts the input power into output power. The drive circuit is disposed on the circuit board, and receives the output power from the power converter. The drive circuit also respectively receives a clock signal and a control command via the clock pin and the data pin, to enable or disable the light source.
