1 is an exemplary view representing a traffic light 10 according to an embodiment of the present invention, Figure 2 is a side view of a traffic light 10 according to an embodiment of the present invention. 3 is a view showing a state in which the traffic light 10 according to an embodiment of the present invention is disposed at the intersection.

1 to 3, the traffic light 10 includes a support part 100, a light emitting member 200, a first auxiliary light emitting member 300, a second auxiliary light emitting member 400, a sign 500, and a sign height. It may include the government (600). The traffic light 10 is a device that is disposed in the pedestrian zone of the intersection and displays the pedestrian time and the pedestrian direction to the pedestrian. The traffic light 10 may emit light toward all directions so that a pedestrian may check a walking time and a walking direction in any direction. In other words, since the traffic light 10 emits light in all directions, the pedestrian can check the signal in all directions.

Furthermore, in the traffic light 10 according to the present invention, when the traffic light 10 is disposed at the center of a pedestrian crossing, the pedestrian can check the signal in all directions. Therefore, the traffic lights 10 need to be disposed at both ends based on the pedestrian crossing. There is no. For this reason, the number of traffic lights installed in the intersection can be reduced.

The support part 100 stands at a constant height on the ground and serves to support the light emitting member 200. The support part 100 may have a bar shape having a vertical direction in a vertical direction. In general, the support 100 may be formed in a cylindrical shape, but is not limited thereto.

The inside of the support part 100 may include a signal control device for controlling the light emitting member 200. The control unit disposed on the support part 100 may exchange various control signals with a device electrically connected to the traffic light 10.

The control unit is a device installed at intersections and pedestrian crossings to control traffic lights. For example, an independent control unit, such as a main control unit (MCU), a signal control unit (SCU), an image detector, etc. Device mounting unit, MMI (man machine interface unit) for the operator connection, the terminal plate for processing input and output signal connection with the external device, and other auxiliary devices, but may vary depending on the intended use.

The light emitting member 200 is disposed on the outer circumferential surface of the support part 100 and emits light. The light emitting member 200 may have a plurality. The light emitting members 200 may be arranged along the length direction of the support 100.

In addition, the light emitting member 200 may emit light toward the front direction when viewed from the top. Since the light emitting member 200 emits light in all directions, the existing traffic lights can check the walking signal only from the front, but the traffic light 10 can check the walking signal in any direction if the pedestrian and the driver have no special obstacle. Can be. Pedestrians and drivers can easily see the signal, making it safer for pedestrians to walk.

According to an embodiment of the present invention, the light emitting member 200 may be disposed in succession with a light emitting diode (LED) displaying at least two colors. The light emitting member 200 may be sequentially disposed to sequentially emit light along the length direction from the lowest light emitting member 200 to the top light emitting member 200 of the light emitting member 200 in response to a walking time. have.

In addition, in accordance with the situation, the light emitting member 200 is continuously arranged in accordance with the embodiment, from the top of the light emitting member 200 to the top of the light emitting member 200 in response to the walking time. Can shine sequentially along the length direction.

Furthermore, the light emitting member 200 has a length from the light emitting member 200 disposed in the middle of the light emitting member 200 to the uppermost light emitting member 200 or the lowermost light emitting member 200 in response to the walking time. Can shine sequentially along the direction.

Here, the light emitting member 200 has been generally used to adopt an incandescent lamp having a filament therein, such an incandescent bulb-type traffic light is not only significantly lower brightness compared to the power consumption, high absolute power consumption, incandescent Since the life of the sphere is short, there is a problem that adds a lot of cost to maintenance.

In general, the bulb's visible light base luminous efficiency is 8.4 lm / W, and the red base luminous efficiency is 0.84 lm / W (assuming a transmittance of 10%). Such bulb traffic lights have very low system efficiency and are continuously lit for 24 hours. It is inefficient lighting equipment such as large energy consumption and impossibility of power demand management, increase of maintenance cost due to frequent maintenance, traffic obstacles, and bad time characteristics due to phantom effect.

On the other hand, in order to solve the above problems of the incandescent light bulb-type traffic light, compared to incandescent light bulbs, the power consumption is about 90%, the lifespan is more than six times longer, and a signal lamp using a light emitting diode having greatly improved visibility has been used.

When the LED light source is combined with a traffic light, the advantages are largely summarized into three. First, energy savings of 80% to 95% can be achieved at the same brightness, and energy savings can be drastically reduced. Second, maintenance costs and smooth traffic flows are induced by 10 times longer lifespan. Third, visibility is improved. This is expected to reduce traffic accidents.

4 is a view showing the operation of the light emitting member 200 according to an embodiment of the present invention.

Referring to FIG. 4, the light emitting member 200 turns on all of the light emitting members 200 in the second color during the time when the walking is impossible, and at the same time as the start of the walking time, all of the light emitting members 200 are turned off. It is lighted with a first color, and then sequentially from the first light emitting member 200 to the light emitting member 200 of the lowermost light emitting member 200 of the light emitting member 200 until the end of the walkable time. Can be converted to

For example, while the light emitting member 200 is unable to walk, all of the light emitting member 200 is turned on in red, and at the same time as the start of the walking time, all of the light emitting member 20 turns green. Lights up. Then, it is possible to indicate that the walking time is reduced to the pedestrian by sequentially changing from the green light emitting member located at the bottom to the light emitting member located at the top until the end of the walkable time, from green to red.

According to the exemplary embodiment of the present invention, the first auxiliary light emitting member 300 emits light toward the front direction when the signal lamp 10 is viewed from above, and the support part (above the light emitting member 200). It may be disposed along the outer circumferential surface of 100).

In addition, the first auxiliary light emitting member 300 may be divided into at least two regions along the outer circumferential surface, and may emit light in a direction indicating region toward a walking direction of the region during a walking time.

For example, when the first auxiliary light emitting member 300 is disposed at two traffic lights with a pedestrian crossing between them on the road, the first auxiliary light emitting member 300 is divided into two regions and divided into two equal parts. The first auxiliary light emitting member 300 positioned in a walking direction among the divided regions may emit light during walking time among the three areas.

For another example, when the four auxiliary lights are disposed at the intersection with the respective crosswalks intersecting each other, the first auxiliary light emitting member 300 is divided into four regions and divided into equal parts. The first auxiliary light emitting member 300 positioned in the walkable direction among the divided areas may emit light during the walkable time of the four areas.

This is to indicate in which direction the pedestrian or the driver is pointing when the traffic light 10 displaying the signal toward all directions has a plurality of traffic lights.

In addition, the direction indicating region of the first auxiliary light emitting member 300 may blink from a predetermined time point of the walkable time to an end point of the walkable time. By the flashing signal of the first auxiliary light emitting member 300, a pedestrian or driver can confirm that the walking time is short without checking the light emitting member 200.

According to an embodiment of the present invention, the second auxiliary light emitting member 400 may be disposed on the light emitting member 200. For example, unlike the second auxiliary light emitting member 400 on the first light emitting member 300, the first auxiliary light emitting member 400 serves to indicate a walking direction in a walking time. The second auxiliary light emitting member 400 allows the driver or pedestrian to predict the time and direction in which the walking is possible at once. Hereinafter, the display of the walking direction to the driver or the pedestrian using the second auxiliary light emitting member 400 will be described.

The second auxiliary light emitting member of the first traffic light and the second auxiliary light emitting member of the first traffic light and the second auxiliary light emitting member of the second traffic light emit light, and during the walking time of the second crosswalk. The member can shine.

For example, the traffic light 10 including the second auxiliary light emitting member 400 disposed on the light emitting member may include a first traffic light, a second traffic light, and a second pedestrian crossing with a first crosswalk interposed therebetween. A first traffic light and a third traffic light disposed between the two may be located. Referring to FIG. 5, the second auxiliary light emitting member 400 has a first crosswalk located between the first traffic light and the second traffic light, and a second crosswalk between the first traffic light and the third traffic light. In this case, the second auxiliary light emitting member of the first traffic light and the second auxiliary light emitting member of the second traffic light emit light during the walking time of the first crosswalk. The light of each second auxiliary light emitting member means that the first traffic light and the second traffic light are currently walking, and that the first crosswalk and the second traffic light can walk in the direction of the first crosswalk. I can display it. The same is true of the second crosswalk located between the first and third traffic lights.

According to an embodiment of the present disclosure, the controller may calculate a walking time for a pedestrian and control the light emitting member 200 in response to the calculated walking time.

Further, the controller sees the light emitting members disposed in the same column among the light emitting members 200 sequentially arranged along the longitudinal direction of the outer circumferential surface of the support part 100 as one light emitting member group, and the entire light emitting member group. The number of times divided by the walkable time, the value multiplied by the elapsed time of the walkable time is calculated as an integer, and then the light emitting member 200 by the number of the light emitting member group corresponding to the calculated value Can be controlled to emit light sequentially.
