Description
LED Pedestrian Signal with Integrated Drainage Function The present invention relates to an LED pedestrian traffic light, and more specifically, to an LED pedestrian traffic light configured to simultaneously serve as a traffic light and a drain during the red signal period. LED pedestrian traffic lights are pedestrian signal auxiliary devices linked with existing pedestrian traffic lights. They are devices that allow pedestrians to see signal information even while looking at the ground by installing LED panels at the crosswalk signal waiting line. In most sections where pedestrian traffic lights are installed, rainwater frequently accumulates on the sidewalks during heavy rain, making it difficult for pedestrians to move. Consequently, situations where vehicles are damaged by the standing water are also frequent. However, installing drainage systems in each section entails many inconveniences and problems, such as getting caught or slipping, when pedestrians use crosswalks. FIG. 1 is a drawing showing the technology used in the present invention internally and externally. FIG. 2 is a simplified drawing showing the upper side view of the present invention. As illustrated in FIG. 1, the LED pedestrian signal light according to the present invention may include an LED panel module (100), a gap control device (200), a foreign matter barrier (201), a signal control circuit (300), a timer circuit (400), and a frame structure (500). The LED panel module (100) represents a panel in which the LED panel of a conventional LED pedestrian traffic light is divided into a certain size. The gap adjustment device (200) is a device that adjusts the connection of the gaps between LED panel modules (100). It opens or closes the gap between LED panel modules (100) in accordance with the signal of the pedestrian traffic light. The gap adjustment device (200) is configured so that the adjustment device closes after a certain period of time when the signal changes from green to red, in order to minimize inconvenience or danger to pedestrians during movement. A foreign matter barrier (201) is added to the space of each gap to minimize the problem of drain blockage caused by other foreign substances such as fallen leaves. The signal control circuit (300) is a circuit that transmits the signal of the pedestrian signal light to open or close the gap control device (200). The timer circuit (400) is a circuit for determining whether the opening or closing time of the gap control device (200) is determined in accordance with the signal of the signal control circuit (300). The frame structure (500) is a structure that connects the gap control device (200) so that it can be opened or closed for a certain period of time according to the signal state. The material constituting the frame is composed of a material that allows the opening and closing of the gap control to be flexible but does not break easily. Figure 2 is a simplified drawing showing the LED pedestrian traffic light of Figure 1 described above as viewed from the top side.
