Abstract
An address-free driving device and lighting fixture system are disclosed. The device is applied in controlling a lighting device, and includes a serial interface, a signal converter, a signal processor and a lighting driving unit. The signal converter converts an inputted signal from the serial interface into a digital signal. The signal processor then extracts a controlling data corresponding to the address-free driving device from the digital signal, and determines whether or not the inputted signal from the serial interface can be outputted to another address-free driving device. The lighting driving unit drives the lighting device to illuminate light based on the controlling data. Accordingly, when the lighting devices are electrically and serially connected, the address-free driving device then controls the lighting devices based on the order of series connection.
