    Abstract: Disclosed is a drive integrated circuit for controlling a traffic light. The drive IC comprises an input end and an output end, an input low-voltage control circuit, a gain control circuit, a driving circuit, an impedance loop and a phase detection circuit. The input low-voltage control circuit connects to the input end of the drive IC, and receives a first external signal. The gain control circuit connects to the input low-voltage control circuit. The driving circuit connects to the gain control circuit. The impedance loop connects to the input end to detect whether the traffic light is damaged. The phase detection circuit connects to the input end to detect a phase difference of the driving signal. By integrating circuits having different detection and control functions in one single chip, the cost of the drive IC decreases and the traffic light can have a less thick structure.

    Abstract: A traffic light including a plurality of light emitting elements and at least one light guide plate is provided. Each of the light emitting elements is configured to emit a light. The light emitting elements are disposed beside a light entering surface of the at least one light guide plate. Each of the lights enters the at least one light guide plate through the light entering surface of the at least one light guide plate.

    Abstract: The illuminated sign includes a frame defining a space, a light emitting module received in the space and having a plurality of light emitting members disposed on a circuit substrate, an optical path conversion component provided on the frame to correspond to the light emitting members, and a light uniformizing component positioned a distance above the optical path conversion component. The space is compartmented to form a predetermined pattern, projecting a desired signal when the light emitting members in different compartments of the space are selectively illuminated.
