Abstract

A parallel type single-wire addressable light device includes a microprocessor, at least one lighting module and at least one signal amplifier. The microprocessor includes an address transmission line and a data transmission line. The plurality of lighting modules is composed of a control driver and at least one lamp set, and the control driver is connected in parallel to the microprocessor through the address transmission line and the data transmission line. The signal amplifier is electrically connected between the microprocessor and the control driver. The address transmission line of the microprocessor transmits an address define signal to set the address of each lighting module, and then the data transmission line outputs data to control any one or any two or more lighting modules for controlling a change of light.
