  • Publication number: 20080136671
    Abstract: A traffic indicator has a base, a circuit board mounted in the base, an LED panel mounted in the base and a protect lid mounted on the base to cover the circuit board and the LED panel. The LED panel is controlled by the circuit board to display traffic lights such as red, green or yellow and traffic symbols such as right and left turn indications. Furthermore, the traffic indicator also displays countdown information about the remaining seconds after which the present displayed traffic light will be changed. Therefore, a single traffic indicator described above is able to replace the conventional traffic lights. Since the traffic indicator has only one display screen, the traffic symbols can be displayed in a larger size to improve the recognition on traffic signs at crossroads.

  • Publication number: 20080136672
    Abstract: A pedestrian light has a base, a circuit board mounted in the base, an LED panel mounted in the base and a protect lid mounted on the base to cover the circuit board and the LED panel. The LED panel has an outer loop region and an inner rectangular region. The circuit board control the inner rectangular region to display a traffic sign such as a walk or a stop sign, and also controls the outer loop region to show countdown information about the remaining seconds after which the present displayed traffic sign will be changed. Since the pedestrian light uses only a single screen to display the traffic sign and countdown information, more space can be saved, and the traffic light can be displayed in a larger size to improve the recognition on traffic signs at pedestrian crossing.
