Abstract

The present invention relates to a green traffic light of a traffic light installed in a crosswalk, characterized in that the graphic (3) of the walking motion is displayed in a dynamic form by the LED lamp (3).

Description

LED green light of crosswalk tr affic light}

The present invention relates to a green traffic light such as a traffic light installed in a crosswalk, and more specifically, a LED lamp displays a walking motion in a dynamic mode in a graphic mode, and a pedestrian crossing indicating the remaining time of walking by varying the speed of the walking motion. It is about LED green traffic light of traffic light.

Utility traffic registration No. 285439 of the present applicant, "traffic light" is introduced.

The traffic light is provided with a housing inside the outer case, an LED lamp inside the housing, a CPU and a lamp driver inside the housing 11, and a power supply and a power socket behind the CPU. Is arranged and supplies power supplied to the power supply through the power socket from the power supply to the CPU and the lamp driver, and the lamp driver is driven by the control of the CPU so that the flashing cycle of the LED lamp is variable, and the LRD lamp The light receiving element disposed at the bottom of the LED senses the external brightness and transmits a signal to the CPU, so that the illumination of the LED lamp is adjusted according to the external brightness.

However, the traffic light has a weak point to attract the attention of the pedestrian by showing a walking signal in the blinking period of the LED lamp.

Accordingly, an object of the present invention is to provide an LED green signal lamp for a pedestrian crossing traffic signal that allows pedestrians to notice the lighting of the lamp, as the LED lamp varies the graphics and displays the walking motion in a dynamic form.

Another object of the present invention is to provide a green LED light of a pedestrian crossing traffic signal that can distinguish the remaining walking time by varying the speed of the walking motion of the graphic.

LED green traffic light of the pedestrian crossing traffic light according to the present invention for achieving the above object is characterized in that the graphics of the walking motion by the LED lamp is displayed in a dynamic form.

The walking motion is divided into four stages, and the walking motion is displayed slowly at a leisurely walking time, and the walking motion is displayed a little faster than the walking time at a leisurely walking time, and the walking motion is displayed quickly at a breaking time, and walking. The waiting time is characterized by displaying a graphic holding one hand.

The walking waiting time may be displayed alternately between the graphic holding the one hand and the reverse count time.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

LED green traffic light (1) of the traffic light for pedestrian crossing according to the present invention is displayed in the dynamic form of the graphic (3) of the walking motion shown in Figure 1a to 1d by the LED lamp.

In addition, the green LED light 1 of the pedestrian crossing traffic light is divided into four steps as shown in Figure 2, walking motion slow walking time of Figures 1a to 1d in walking time (WT) Displayed, for example, indicates that a pedestrian can cross the crosswalk at a leisurely walk of 100 steps per minute, and the walking motion of FIG. 1A to FIG. It shows that a pedestrian can cross the crossing at a normal walking speed of 150 steps per minute, and the pedestrian crossing speed is displayed quickly at the breaking time (FT) to show that the pedestrian crosses the crossing at 200 steps per minute. At the next walking waiting time (AT), as shown in Fig. 3, the graphic 3 holding one hand is displayed so that a pedestrian does not cross the crosswalk and waits for the next signal. It indicates that the reel. In addition, the stop graphic 3 is displayed as shown in FIG. In particular, as shown in FIG. 5, the walking waiting time AT may alternately display a graphic holding one hand and an inverse count time.

The leisurely walking time (WT), normal walking time (NT), breaking time (FT), walking waiting time (AT) is divided by the rate because the flashing time of the traffic light is variable, and generally the overall walking time 35% of walking time (WT), 30% of normal walking time (NT), 25% of breaking time (FT), and 10% of walking waiting time (AT).

The LED green traffic light of the pedestrian crossing traffic light may be lit with green or blue LED lamps, displaying a background color in blue, and displaying a graphic in green, so that the walking time (WT) and the normal walking time (NT) ), The graphic lights up in green, the background color lights up in blue at the same time, the background color is turned off, and the stop graphic is displayed in green at the breaking time (FT) and walking waiting time (AT). .

As described above, the LED green traffic light of the pedestrian crossing traffic light according to the present invention, as shown in FIG. Can be controlled. That is, the first module 13a represents the head of the graphic 3, the second module 13b is the body of the graphic, and the third and fourth modules 13c and 13d are the arms of the graphic, the fifth and the fifth. The six modules 13e and 13f can express the leg motion of the graphic.

As described above, the LED green traffic light of the traffic light for pedestrian crossing according to the present invention is the LED lamp variable graphics to display the walking motion in a dynamic form, the pedestrian can notice the lighting of the lamp, the walking motion of the graphic By varying the speed of the walking remaining time can be distinguished effect.

Claims (3)

LED green traffic light of the pedestrian crossing traffic light, characterized in that the graphic of the walking motion (3) is displayed by the LED lamp in a dynamic form. The method of claim 1, The walking motion is divided into four stages. The walking motion is displayed slowly in the walking time (WT), and the walking motion is displayed a little faster than the walking time (WT) in the normal walking time (NT).
