Description

Light emitting pedestrian crossing and construction method therein}

The present invention relates to a light emitting crosswalk that prevents a traffic accident of a driver or a pedestrian and a construction method thereof, and in particular, does not damage or deform due to impact due to vehicle traffic and load, as well as damage to an electronic device due to moisture infiltration. It relates to a light emitting crosswalk and a construction method thereof that can prevent safety accidents.

In general, crosswalks are marked on the road surface to allow pedestrians to cross the road safely. In addition, streetlights are installed on pedestrian crossings located on roads with a lot of traffic and pedestrian crossings, allowing pedestrians to cross the road safely.

However, the general street lamp as described above should not disturb the driver's view of the driving car, so the brightness is relatively dark, so that people or objects at a short distance can be identified. There is a problem that is not easy to identify.

In view of this point, Korean Utility Model Registration Application No. 20-2000-6419 discloses a traffic light pole assembly with a pedestrian protection lamp. The disclosed assembly is intended to enhance the safety of pedestrians by attaching an illumination lamp for illuminating the crosswalk to a vehicle control signal light installed at a position adjacent to the crosswalk and illuminating the crosswalk at night. However, such assemblies tend to have the light emitted from the lamps narrow the field of view of the vehicle driver.

In addition, Korean Patent Application No. 10-2000-71950 discloses a lighting device for a crosswalk. The disclosed lighting device is installed in a position adjacent to the crosswalk to protect the pedestrians by intensively illuminating the crosswalk, and the driver focuses only on the road surface in front of him. There is a problem that visibility is reduced by interference of

In addition, the method of irradiating the crosswalk with the illumination from the upper side of the crosswalk, that is, the upward illumination method is inconvenient to use a separate lifting device in order to replace the lights, a plurality of vehicles on the upper side of the pedestrian traffic As lighting lamps are installed, there is a risk of safety accidents caused by falling.

On the other hand, the pedestrian cross-linked light emitting display device shown in Korea Utility Model Publication No. 20-0265874, the rectangular box-shaped body, the reflector and reflector, which is accommodated in the body and fixed by screw coupling, LED installed in the reflector, It is provided with a fixed cover that is screwed to the main body and is embedded in the crosswalk to emit light. The light emitting display device described above solves the above-mentioned problems of the up-illumination method as it is embedded in a road surface, but has a problem that it is difficult to use a crosswalk that must withstand driving shock and flow load caused by a heavy vehicle.

That is, when a vehicle of several tons to tens of tons impacts the reflector of the light emitting display device by high-speed driving or load, the reflector or the coupling portion between the reflector and the main body may be deformed or damaged. In addition, when moisture penetrates into the micro-gap in the deformed or damaged reflector or the coupling part, there is a risk of a safety accident of a pedestrian by causing a breakdown of the LED or a short circuit. In particular, since the reflector and the main body are screwed together, it is difficult to maintain a strong coupling due to repeated impacts of the traffic of the vehicle, and the road surface of the crosswalk is always exposed to rain or snow moisture, which is very vulnerable to the above-mentioned electrical stability. .

In addition, since the light emitting display device is buried in the incision of the road with epoxy or urethane, the device may be detached from the road when the impact is severe because it is not firmly fixed to the incision surface. The wire pipes are buried in the road for connection, but there is a problem in that a connection of the wires is shorted due to moisture infiltration into the wire pipes.

The present invention was devised to solve the above-mentioned conventional problems, and it is possible to reliably recognize the crosswalks for drivers and pedestrians without disturbing the driver's view, thereby minimizing the risk of traffic accidents and driving shock of the vehicle. Its purpose is to provide an electrically safe luminescent crosswalk from moisture infiltration without damage or deformation under excessive loads.

The method of claim 13, The flow preventing bar 17 is light emitting crosswalk, characterized in that the surface is formed to be inclined. In the method of constructing a crosswalk that is emitted on the road surface, (a) cutting the road surface to a predetermined depth so that the light emitting plate-like body 1 containing the point light source 5 is embedded; (b) providing fixing means for the light emitting plate-like object 1 on the incision surface; (c) arranging the light emitting plate member 1 on the fixing means so as to show the display line L indicating the crosswalk; And (d) connecting and embedding the wires (7) drawn from the light emitting plate-shaped body (1) installed in different positions; light emitting crosswalk construction method comprising a. The method of claim 15, In step (b), The fixing means of the light emitting plate 1 is characterized in that the mortar 80, or the upper portion of the light emitting plate (1) is opened and the receiving frame 16 is provided with a storage space to accommodate the plurality of light emitting plate (1). Light emitting crosswalk construction method. The method of claim 16, In step (d), The lower case 19 is seated with a connector connecting portion 18 connecting the wires 7 drawn from the light emitting plate bodies 1 installed at different positions to the lower case 19, and the wires 7 enter and exit through both ends. Light-emitting pedestrian crossing construction method characterized in that the step of embedding the upper case (20) by the interference fit. The method of claim 17, Filling the filler (21) through the injection groove (20a) provided on one surface of the upper portion (20) or the lower case (19); light emitting crosswalk construction method further comprising. delete delete delete
