Abstract

(57) [Summary] [Purpose] The location of roads and roads where warnings should be displayed is displayed so that vehicles do not deviate from the road or accidents occur between vehicles, especially on the road surface at night or during rainy weather. The purpose of the present invention is to embed a warning light-emitter to cause the entire device to emit light and enhance the warning-guide effect. [Structure] A light emitting diode and the substrate itself are encapsulated and molded into a special synthetic resin with light diffusing properties containing minute special glass beads to form a light emitting body, and the light emitting body surface is exposed to the road surface by connecting with a metal housing. By embedding in such a manner, the large-area light emitting portion exposed on the road surface emits light over its entire surface to achieve the intended purpose.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is intended to prevent the collision of vehicles with each other due to deviation of the marking line due to driver's carelessness, or collision with roadside structures, by demonstrating the bending alignment by installing a plurality of road alignments, particularly at bends. The present invention relates to a self-luminous induction device.

[0002]

[Prior art]

 It is pointed out that there are many curved roads especially in the mountainous areas, but when driving over long distances and reaching the mountainous areas, traffic volume decreases, tension is felt and sleepiness occurs. In such a case, a sharp curve is very dangerous, and a large accident such as a departure from the road or a collision with an oncoming vehicle on a narrow road with a narrow road is likely to occur. There are currently no facilities to resolve this situation.

[0003]

[The purpose of the device]

 The present invention was devised for the purpose of preventing traffic accidents by responding to the conditions of roads and drivers under such conditions.

[0004]

[Means and actions for solving the problem]

 In order to solve the above-mentioned problems, the present invention makes the upper surface almost flat with the road surface so that the steering wheel is not taken when the traveling vehicle accidentally steps on the guidance device of the present invention on the lane marking or the center line. By burying a plurality of parts as described above and making the entire top surface of the guidance device emit light, it helps guide the line of sight at night, especially in the case of poor visibility in the case of rain or fog, and the driver unintentionally deviates from the lane. When attempting to do so, the main body of the device and the anti-slip projections on the top of the main body allow the driver to sense an impact to the extent that it does not jeopardize the progress of the vehicle and prevent the driver from falling off while falling asleep. The purpose is to fulfill.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of an embodiment of the present invention. A light emitting part 1 which is a special synthetic resin body having light diffusing property, and a metal casing 2 for fixing and protecting the same are fixed with bolts 3, and an outer frame 2 ′ of the casing 2 and the light emission fitted in the casing. It is embedded in the pavement 4 so that the upper surface of the portion 1 is exposed to the road surface. Inside the housing 2 below the light emitting unit 1, a power source and a signal device or a connecting portion of an electric wire necessary for blinking light emission of a single device or a plurality of devices are housed.

The light emitting section 1 has a plurality of light emitting diodes (LEDs) 5 arranged therein and is integrated with a wiring board 5 ′ by a special synthetic resin having a light diffusing property. It is integrally molded including the reinforcing steel plate 6 so that it can withstand impact. On the upper surface of the light emitting portion 1, there are provided projections 7 for preventing slipping when the vehicle tire is crossed over. The light emitting unit 1 can be removed and maintained by removing the bolt 3 even after the device is embedded. At this time, in order to reinforce the metal plate 6, the welding nut 9 which is thicker than the diameter of the connecting bolt 3 is used to facilitate the detachment of the light emitting body 1 from the fitting with another thick detaching bolt.

The special synthetic resin body of the light emitting section 1 of the device is mixed with special glass beads having a small diameter and having a light diffusing property, and the light emitted from the LED 5 is diffused through the glass beads and further diffused. And the directivity, which is also a drawback of the light emission of the LED, is eliminated, and the light emitting section 1 emits the entire surface and the light emitted on the road surface clearly warns and guides the night driver.

By connecting a power cable and a signal cable, a plurality of guides can be taken at the same time, such as simultaneous flashing, alternating flashing, and sequential flashing, depending on the traffic conditions on the installed road.

Since a power-saving light source such as an LED is used, it can be installed using a solar cell or the like at a place where there is no commercial power source, such as a mountain area.

Since the light emitting portion is a resin molded product, the emission color of the entire surface light emitting body can be selected from red, blue, green, orange and the like according to the purpose of regulation, induction and the like. Even if the surface is worn, the luminescent color does not change. It is also possible to select a combination such that the light emitting portion is made of white translucent resin to emit white light in the daytime and red or yellow at night.

[0012] The light emitting part of the device is made to protrude beyond the metal casing, and the entire side surface of the light emitting part is made to emit light without being embedded in the road surface and installed on a median strip or a roadside curb to be used for warning guidance. It is also possible. In this case, an anti-slip protrusion or the like is not necessary on the upper surface. (Fig. 4)

[0013]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

Since the light emitting device of the present invention is a surface light source, it can reduce the unevenness of the road surface when it is embedded in a road pavement body, and can be used in the case of a sharp curve or an orthogonal road. It is easy to see from any direction, and the desired warning guidance effect can be easily exerted in any area with relatively low cost.
