Floor traffic lights with animation functionk}

The present invention relates to a floor traffic light with an animation function, and more specifically, by efficiently providing not only crosswalk signals but also various information to pedestrians through animation effects, thereby increasing utility and greatly contributing to improving pedestrian visibility. This relates to a floor traffic light that helps with the safety of pedestrians, is easy to maintain and repair due to the bracket attachment and detachment structure on the ground, and has an animation function that allows easy installation even in curved sections.

In general, crosswalk traffic lights are installed at the eye level of pedestrians, but since the signals can only be seen by raising their heads, for example, it is not easy for pedestrians with their heads down to check the crosswalk signals.

In order to improve this problem, floor traffic lights that are controlled in conjunction with crosswalk traffic lights are installed and used on sidewalks near crosswalks or on the floor within crosswalks.

This type of floor traffic light installs an LED inside a transparent or translucent case and emits red or green light from the LED to indicate the current pedestrian crossing signal. As a result, the use of smartphones has recently increased. , Not only does it significantly prevent traffic accidents caused by pedestrians who lower their heads and focus on their smartphone screens without paying attention to their surroundings, but it also contributes greatly to preventing traffic accidents for various types of pedestrians by increasing the visibility of traffic signals. I'm doing it.

The control unit 170 may be installed in the enclosure of a device that controls floor traffic lights, or may be installed integrally in a road traffic light system. The control unit 170 is not limited to this and may be installed independently or in combination with other systems at various locations, as an example. The LED substrate 130 can be controlled to turn on light corresponding to a road traffic light according to a road traffic light control signal provided from a road traffic light system, etc., and as another example, animation is performed by a predetermined process according to the operation of the road traffic light. The LED substrate 130 can be controlled to achieve the effect. In order to achieve an animation effect, the control unit 170 displays a desired symbol, character, or figure per frame by blinking each of the LEDs 131 on the LED substrate 130, taking motion into account, and displays each of these frames continuously. By displaying it as an effect that allows the LED substrate 130 to express continuous movement, for example, as in the example of FIG. 9, by including processes (a) to (h) to be performed continuously, various types of The shape of the arrow movement can be displayed, and for this purpose, each LED 131 of the LED substrate 130 can be controlled to guide pedestrian movement in the direction of the arrow. In addition, as in the other embodiment of FIG. 10, the control unit 170 includes sequentially performing steps (a) to (i), so that the LED of the LED substrate 130 displays the remaining time allowed for walking, which is counted in the timer.
