The present invention relates to a floor-type walking traffic light, and more particularly, to a floor-type walking traffic light capable of enhancing pedestrian visibility without interfering with the driving of a vehicle driver.

In general, crosswalks enable vehicles to safely cross the road, and are mainly provided at intersections of roads or other places where there are many road crossers.

In such a crosswalk, it is common that a crosswalk signal light is installed to periodically display a stop signal and a crosswalk signal, and the crosswalk signal light is installed at a certain height from the floor surface through a support.

The crosswalk traffic light is installed at the eye level of the pedestrian, but it is necessary to raise the head to check the signal. In this case, pedestrians fail to cross despite the crossing signal, or belatedly recognize the crossing signal and cross in a hurry to collide with vehicles.

Recently, in order to solve the above problems, floor-type walking traffic lights controlled in conjunction with crosswalk traffic lights are buried at the boundary between the road and the sidewalk so that pedestrians with their heads down can clearly and quickly recognize the signal change of the traffic lights.

However, due to the nature of the conventional floor-type walking traffic light buried in the ground at both ends of the crosswalk, it is difficult for pedestrians waiting for the traffic light to easily identify the floor-type walking traffic light, so the floor-type walking traffic light does not faithfully perform its original function, On the contrary, since the driver of the vehicle can easily identify the floor-type walking traffic light, there is a problem in that safe driving is hindered due to conflicting signal lights between the traffic light and the floor-type walking traffic light that the driver is looking at.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in describing the present invention, descriptions of already known functions or configurations will be omitted to clarify the gist of the present invention.

Example 1

1 and 2, the floor-type walking traffic light according to this embodiment includes a main body 1, a support module 2, an LED module 3, and a cover 4.

At least one or more floor-type walking traffic lights according to this embodiment are installed in a line at the boundary between the roadway and the sidewalk of the crosswalk, and these floor-type walking traffic lights have a structure that is controlled in conjunction with the crosswalk traffic lights.

The main body 1 is buried and installed at the boundary between a road and a sidewalk where a crosswalk is installed. The body 1 has a structure in which the support module 2, the LED module 3 and the cover 4 are installed.

Referring to FIG. 3 , the support module 2 is installed in a horizontal state on top of the main body 1 . The support module 2 is formed with a plurality of LED installation parts 20 inclined at a predetermined angle toward the pedestrian direction on the upper surface so that a plurality of LED modules 3 can be divided and installed. The LED installation unit 40 has a structure that is disposed elongately along the longitudinal direction with a mutually predetermined interval on top of the support module 2 .

The LED installation unit 20 is formed to be inclined at an angle of 10 degrees in the pedestrian direction based on the horizontal state of the support module 2 so as to increase pedestrian visibility without interfering with the driving of the vehicle driver. The reason why the LED installation part 20 is formed to be inclined at an angle of 10 degrees in the direction of the guide is that it must be designed to be inclined at 10 degrees in the direction of the sidewalk according to the standard guidelines for auxiliary devices for floor-type walking traffic lights passed by the National Police Agency in March 2019. to satisfy the requirements.

Here, the number of LED installation parts 20 formed on the upper surface of the support module 2 is not limited to the number shown in the drawing, and may be increased or decreased as needed when designing the structure of the floor-type walking traffic light.

The LED module 3 is installed on the LED installation part 20 of the support module 2 . This LED module 3 has a structure that is turned on in conjunction with a crosswalk traffic light. For example, the LED module 3 is controlled in conjunction with a crosswalk traffic light so that it is turned on in red at the time of a vehicle signal and in green at the time of a walking signal.

The LED module 3 is divided and installed in a plurality of LED installation parts 20 formed on the upper part of the support module 2, and accordingly, the height deviation between the LED module 3 and the cover 4 can be minimized. Therefore, the light of the LED module 3 passing through the cover 4 is uniformly luminous over the entire area of the cover 4, so that glare of pedestrians or drivers can be prevented.

That is, the conventional LED module is formed as an integral structure and is installed at an angle of 10 degrees to the upper part of the main body. Due to this structure, a severe height deviation may occur between the inclined lower area and the inclined upper area of the LED module based on the cover. Inevitably, when the surface of the cover emits light, severe glare occurs on the surface of the cover corresponding to the inclined lower area of the LED module due to the height difference between the cover and the LED module, which not only causes inconvenience to pedestrians but also hinders the driver's driving. interfered

Therefore, in this embodiment, the LED module 3 is divided and installed in the plurality of LED installation parts 20 formed in the support module 2 to minimize the height deviation between the LED module 3 and the cover 4, thereby covering the cover 4 ), it is possible to achieve surface light emission of uniform luminance without glare over the entire surface area of the cover 4 when light is emitted.

The cover 4 is installed to completely cover the upper part of the main body 1. A diffusion pattern 42 having a concavo-convex structure capable of diffusing light emitted from the LED module 3 is formed on the entire inner area of the cover 4. The diffusion pattern 42 has a structure that refracts and reflects the light of the LED module 3 passing through the cover 4 in a single direction and diffuses it widely.

Here, since the diffusion pattern 42 is a well-known technique widely applied by those skilled in the art, a detailed description thereof will be omitted.

The cover 4 is formed with a plurality of non-slip protrusions 44 on the upper surface. The anti-slip protrusion 44 is to prevent a pedestrian from slipping from rain or snow.

The cover 4 is formed of a high-strength synthetic resin of a translucent material to protect the support module 2 and the LED module 3 from external impact and to radiate the light of the LED module 3 to pedestrians.

Hereinafter, the operating state of the floor-type walking signal lamp according to the present embodiment will be described in more detail.

First, the floor-type bohyeong traffic light according to this embodiment has a plurality of LED installation parts 20 inclined at a predetermined angle toward the pedestrian direction on the upper surface of the support module 2 installed between the main body 1 and the cover 4 ) is formed, and the LED module 3 is installed in the LED installation part 20, so that the light of the LED module 3 is maximally emitted in the direction of the pedestrian when controlled in conjunction with the crosswalk traffic light, and thus the light directed to the vehicle driver. It is possible to increase the pedestrian's visibility by minimizing the driving disturbance and increasing the light directed to the pedestrian.

Referring to FIG. 4 , the LED module 3 is divided and installed in the LED installation part 20 formed on the support module 2, thereby minimizing the height deviation between the LED module 3 and the cover 4. That is, the LED module 3 is divided and installed in the plurality of LED installation parts 20 formed in the support module 2, unlike the conventional installation structure of the integrated LED module, and the height between the LED module 3 and the cover 4 A structure that can minimize the deviation is secured.

Therefore, the floor-type walking traffic light of this embodiment provides a structure in which the height deviation between the LED module 3 and the cover 4 can be minimized, so that when the surface of the cover 4 emits light, it covers the entire surface area of the cover 4. It is possible to prevent driver's driving disturbance while guaranteeing safe walking of pedestrians by ensuring surface light emission of uniform luminance without glare caused by height deviation.

In addition, the LED module 3 provides a structure that is independently divided and installed in the LED installation part 20 of the support module 2, so that a quick response is possible when the LED module 3 fails. That is, since the AD module installed in the existing floor-type walking traffic light adopts an integrated structure, there is a structural problem in that the entire LED module must be replaced when some LEDs fail, but the floor-type walking traffic light of this embodiment is supported. Since the LED module 3 can be independently divided and installed in the plurality of LED installation parts 20 formed of the module 2, it is possible to individually replace the LED module 3 in case of failure, thereby facilitating replacement and reducing costs. This will ensure the convenience of management.

As described above, the floor-type walking traffic light according to the present embodiment minimizes the light of the LED module 3 directed to the driver of the vehicle to reduce driving disturbance while increasing the light of the LED module 3 directed to the pedestrian on the contrary. To increase the visibility of the cover by minimizing the height deviation between the LED module 3 and the cover 4 by dividing and installing a plurality of LED modules 3 in the support module 2 installed on the upper part of the main body 1. In the entire area of (4), surface light emission of uniform luminance without glare due to height deviation can be achieved.

In addition, in the floor-type walking traffic light according to this embodiment, as the LED module 3 is independently divided and installed in the LED installation part 20 of the support module 2, when the LED module 3 fails, individual replacement is possible. It is possible to secure the convenience of maintenance and management through the ease of replacement and cost reduction.

The driven roller 52 is installed below the support module 2 to be spaced apart from the driving roller 50 at a predetermined interval. The driven roller 52 is interlocked with the driving roller 50 .

Referring to FIG. 7, the driving roller 50 and the driven roller 52 are connected by gears or belts for interlocking rotation, and the driving roller and the driven roller of this embodiment have a structure in which they are connected via a gear 53. . That is, a pair of gears 53 interlocking with each other are installed on the driving roller 50 and the driven roller 52, and thus the driving roller 50 and the driven roller 52 can be interlocked.

A plurality of guide rollers 54 are installed inside the cover 4 so as to be disposed around the support module 2 and the LED module 3. The guide roller 54 serves to guide the movement of the light blocking film 56 inside the cover 4 .

The light blocking film 56 is installed to be guided along the guide roller 54 by wrapping the outside of the support module 2 and the LED module 3 in a state of being wound around the driving roller 50 and the driven roller 52, respectively. The light shielding film 56 is formed with an opening 57 for exposing the light of the LED module 3 toward pedestrians. The opening 57 of the light blocking film 56 is located above the support module 2 so that the light of the LED module 3 can be radiated toward the pedestrian.

The control unit 58 places the opening 57 of the light blocking film 56 above the support module 2 so that the light of the LED module 3 interlocked with the crosswalk traffic light can be emitted in the direction of the pedestrian, but the crosswalk traffic light The operation of the driving roller 50 is controlled so that the light emitting state of the LED module 3 can be adjusted according to the change in the position of the opening 57 in order to notify the pedestrian of the signal conversion time during the blinking operation according to the signal conversion of .

That is, the control unit 58 moves the position of the opening 57 by the winding operation of the driving roller 50 and the unwinding operation of the driven roller 52 during the blinking operation according to the signal conversion of the crosswalk signal light to move the LED module 3 The light emission state is gradually reduced and adjusted to be blocked, and the position of the opening 57 is moved by the unwinding of the driving roller 50 and the winding operation of the driven roller 52 when the light is turned on with a new signal system after the blinking operation of the crosswalk traffic light. It has a structure in which the light emitting state of the LED module 3 gradually increases and is controlled so that it is fully exposed in the pedestrian direction.

Hereinafter, the operating state of the floor-type walking signal lamp according to the present embodiment will be described in more detail.

Referring to FIG. 8, the opening 57 of the light blocking film 56 constituting the floor-type walking traffic light according to the present invention is controlled by the control unit 58 to be located above the support module 2, thereby interlocking the crosswalk traffic light. When controlling, it is possible to notify pedestrians of vehicle signals or walking signals.

That is, the control unit 58 operates the driving roller 50 by the driving motor 51 to position the opening 57 of the light shielding film 56 above the support module 2 so that the light of the LED module 3 can be diverged to the maximum in the direction of the pedestrian.

Referring to FIG. 9 , the control unit 58 moves the position of the opening 57 by winding the driving roller 50 and unwinding the driven roller 52 during a blinking operation according to signal conversion of a crosswalk signal light so that a pedestrian The light emitting state of the LED module 3 radiating toward the is gradually reduced and adjusted to block the light, and when the light is turned on with a new signal system after the blinking operation of the crosswalk traffic light, the driving roller 50 is released and the driven roller 52 is wound.
