Abstract

According to the present invention, a traffic signal is turned on by using an electromagnet and a spring according to a state of an electric signal which is attached to a conventional traffic signal and the same color as each color and supplied and cut off when the traffic signal flashes. It is a vertical position that can be recognized by drivers and pedestrians in city, and it operates in a horizontal position that cannot be recognized at the time of extinction, eliminating the difficulty of discriminating the signal due to high brightness of sunlight and solar backlighting at sunset and sunrise, It is an auxiliary device for traffic lights to serve as an auxiliary signal for disconnection, color weakness, color blind driver and pedestrian.

The present invention uses the electric signal that is attached to a conventional traffic signal lamp and supplied and cut off at the time of flashing lights such as the Kyo-Communication Lake to operate the auxiliary display at the same time with the traffic signal to solve the difficulty of discriminating the signal by daylight sunlight It serves as a supplementary signal to drivers and pedestrians to reduce daytime traffic accidents on kyo lanes and sidewalks.

Conventional traffic lights use light generated from light bulbs, and it is not easy to distinguish traffic signals in a short time due to high brightness of sunlight during sunny weather or low-angle front sunshine during sunset or sunrise. In pedestrian crossings where intersections and traffic lights are installed, drivers are suddenly braked, sudden departures and departures by the starting horns of rear vehicles, and the traffic condition is estimated based on experience.

The present invention solves the conventional problems as described above, by supplying the DC power to the coil of the iron core using the power supplied at the time of lighting without changing or expansion of the program, hardware and signal line of the traffic light control system and operating the iron core by electromagnet The auxiliary display panel attached to the permanent magnet is moved to the vertical position and when the power is disappeared, the auxiliary display plate is moved to the horizontal position by the spring so that the driver and pedestrian can recognize the traffic light of the corresponding color in the same way.

When described in detail according to the accompanying drawings as follows.

1 is a front view, imagining the case in which the left turn green signal is turned on. In this case, only the left turn green cover plate 8 is vertically positioned and the remaining auxiliary display panels 6, 7, 9 are horizontally positioned. As a form of a signal, it can be applied to three colors and two colors. Referring to the configuration of the present invention in Figure 2 and Figure 3, inside the traffic light (1) there is a DC converter 11 for changing the AC to DC when an AC voltage is applied to light the traffic light of the corresponding color Electromagnet wires 12, 12 'for supplying the output of the DC converter 11 to the coil 18 of the iron core 15 are connected, and direct current power supply through the electromagnet wires 12, 12'. When this is supplied, an iron core 15 acting as an electromagnet, and a coupled permanent magnet 14 having the same polarity per both sides for changing the display angle of the auxiliary display panel 16 attached to the magnetic field formed on the electromagnet are provided. In addition, a spring 13 for restoring the auxiliary display panel 16 to a horizontal position when the traffic light of the corresponding color is turned off or a power outage and a mounting plate 17 for attaching the present invention to the conventional traffic light 1 are also provided. The configuration described above should be equal to the number of traffic light colors.

The operation of the present invention configured as described above will be described.

As shown in FIG. 4, the permanent magnet 14 coupled when the power source for the traffic light (220V AC) is not applied, is assisted by the restoring force of the spring 13 and the coupling force of the N pole and the iron core of the permanent magnet. The display panel 16 maintains a horizontal position.

As shown in FIG. 5, when a power source (220V AC) for lighting a signal lamp is applied, a DC power is applied to the coil 18 via the DC changer 11 so that the iron core 15 has an electromagnet having the polarity as shown in the drawing. Spring 13 which satisfies the condition of N pole-S pole pulling force ?? Resilience of spring ?? (N pole-S pole pulling force) + (N pole-N pole pushing force) In this case, the bonded permanent magnet 14 moves to the S pole of the electromagnet so that the attached auxiliary display panel 16 maintains the vertical position. In addition, when the bulb is disconnected, the garden is supplied to the DC converter 11 when the power supply for the traffic light (220V AC) is applied, so that the auxiliary display panel 16 operates in a vertical position to prevent traffic congestion and accidents during the day. can do.

When the signal light of the corresponding color is turned off or blackout, that is, when the power source (220V AC) for the signal light disappears, the iron core 15 does not operate as an electromagnet, and the combined permanent magnet 14 satisfies the above condition (??). By the restoring force of the spring 13, the auxiliary display panel 16 attached and returned to the position as shown in Fig. 4 maintains the horizontal position.

As described above, the present invention operates by the same period as the flashing of the traffic signal by attaching and connecting the conventional traffic signal without changing the main control device of the traffic light, and also operates at the time of disconnection of the light bulb, thereby eliminating the difficulty of signal discrimination. And pedestrian crossing is effective to reduce the accident.
