The present invention relates to a lane guidance lamp (Lamp), and more particularly to a lane guidance device that can stably perform the lane guidance by controlling the lights of the left turn lane along with the left turn signal system at the left turn of the intersection.

In general, lane markings on roads are installed and fixed in lanes or on the center line so that the driver can move away from the lanes of the road through reflected light from the headlights of the vehicle, especially when the vision in front of the vehicle is poor due to nighttime, rainy weather or fog. It can be easily recognized to the street, thereby promoting safe driving, and in particular, it is used to prevent vehicle collision accidents caused by sudden curve roads or lane violations.

Such lane indicators may be in the form of tapes or sheets, or in the form of protrusions fastened on roads. For example, a conventional lane marking tape is bonded to a non-woven fabric on the upper surface of a tape body made of aluminum foil or the like, and laminated thereon with a fluorescent display portion mixed with an epoxy resin and a glass powder, and heat-cured at a predetermined temperature. The bottom surface of the main body is formed by applying an adhesive to form an adhesive layer and covering the adhesive surface with a paper.

However, since the tape was used as it is mixed with a non-spherical (random) glass powder in a paint or a resin, there was a problem that the day and night visibility of the lane is insufficient because the luminance ratio is retroreflected very low.

On the other hand, the protruding lane indicator is installed at a predetermined interval on the center separation line 14 including the lane 12 of the road as shown in Figure 1 of the accompanying drawings, first of each of the body 16 made of a hexahedron On the side, a reflector 18 formed in a plane is attached and fixed to reflect the reflected light in the corresponding direction, and the bottom of the body 16 is buried on the lane 12 and the center dividing line 14 of the road. In order to fix the position of the lane indicator 10, the fixing member 20 having a predetermined length is formed downward and protrudes.

Therefore, in order to install the lane indicator 10 configured as described above in order to promote safe driving of the vehicle on the road, first, a predetermined depth is used by using a drill generally used along the lane 12 or the center separation line 14. After the groove is formed, the fixing member 20 of the lane indicator 10 is inserted into the groove. When the vehicle is installed in the above state at night, the reflector 18 installed in the lane display 10 by the headlight of the vehicle emits light and is reflected in the corresponding direction. The situation can be easily recognized, and accordingly guided to safely drive up and down curved roads or hills.

By the way, the conventional lane display 10 as described above is a reflector 18 is attached to the side of the body 16 formed in a rectangular plane so that the reflection effect of the reflector 18 in a straight road or a slight curve road Although it is large, a sharp curve or up and down slopes cause a limitation in the reflection angle of the reflector 18, which is made of a flat surface, so that the reflection effect is remarkably decreased. If it is narrow or defective, there is a problem in that the vehicle serves as a lane indicator 10 and causes traffic accidents.

On the other hand, as described above, the tape-shaped lane display device or the protruding lane display device is installed and operated with its advantages and disadvantages. However, the lane display devices used in recent years are applied only to straight and curved roads. That is, such a lane display device is not used at an intersection, so it is difficult to maintain a lane for turning left (or turning right) at night or in bad weather. Of course, a lane for a left-turning vehicle is shown at the intersection, which is difficult to recognize at night unlike the above-described tape or protruding lane display.

Of course, if the tape-shaped or protruding lane display device is installed and operated at the intersection, that is, all left turn lanes in the intersection will cause chaotic lanes for all vehicles operating in the intersection. Therefore, there is a need for an induction device capable of safely rotating while turning left the vehicle at the intersection.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2A and 2B are perspective views illustrating a lane guidance apparatus according to a first embodiment of the present invention. According to the present exemplary embodiment, the housing 201 having a predetermined shape and one side surface is opened, and coated with glass beads to transmit reflected light in a fixed direction built into the housing 201, and then tilted at a predetermined angle. The glass bead surface 207 is fixedly installed, the lamp driver 211 is built in the front of the glass bead surface 207 is turned on according to a traffic light (not shown) control pattern, the lamp driver 211 and The transparent window 205 and the transparent window 205 fixed to the opening surface of the housing 201 to protect the glass bead surface 207 from external force and transmit the reflected light of the glass bead surface 207, It is composed of a fixing panel 203 for fastening with the housing 201.

The lamp driver 211 includes a lamp 213 installed to face the glass bead surface 207 and a power line 209 for supplying power to the lamp 213. The power line 209 extends using one side of the housing 201 and is connected in parallel with a plurality of lane guidance devices. The power line 209 is supplied with power in synchronization with a specific signal such as a traffic light.

The lane guidance device configured as described above is preferably applied as a lane in a left turn (or right turn) direction at an intersection area, and is drawn and buried on a road. Accordingly, the housing 201 of the lane guidance apparatus is fixedly installed on the inner surface of the road, and the fixing panel 203 and the transparent window 205 are led to the road surface. Here, the fixing panel 203 of the present invention is thin so that there is no jam in the movement of the vehicle. In addition, the transparent window 205 is made of a material such as tempered glass or high compression plastic, and is designed so as not to overload the load above the reference value.

When a plurality of lane guidance apparatuses according to the present invention are connected in parallel and embedded on a road, the power supply line 209 makes an electrical connection to be synchronized with a specific lamp such as a traffic light. For example, when the lane guidance apparatus is applied to the left turn lane of the intersection, the lane guidance device applied for the left turn lane is turned on in response to the left turn light of the traffic light. That is, the lamp 213 is turned on, and the light source is radiated to the glass bead surface 207. The glass bead surface 207 reflects the light source of the lamp 213 in a predetermined direction.

Since the reflected light of the glass bead surface 207 has to be scanned into the driver's seat of the left-turning vehicle, the glass bead surface 207 is provided to face the front of the driving vehicle. In addition, the installation angle of the glass bead surface 207 is preferably 30 kPa to 45 kPa. The glass bead surface 207 described above is applied as a means for emphasizing visibility, and even if a microsphere lens is used instead of glass beads, it will not depart from the gist of the present invention. In addition, the glass bead surface 207 may be lane guided by the light source of the vehicle in the lamp 213 is turned off. This is to allow the left turn lane guidance to be performed even in an error state in which the lamp 213 is turned off. Accordingly, the driver safely performs a left turn along the left turn lane that is turned on at the same time as the left turn signal light.

3A, 3B and 3C illustrate another embodiment of the present invention. In this embodiment, the solar cell is mounted on the lane guidance apparatus. As shown in the drawing, the housing 201 having a predetermined shape and one side surface is opened, coated with glass beads to transmit reflected light in the fixed direction built into the housing 201, and then tilted and fixed at a predetermined angle. The glass bead surface 207 to be installed, the solar cell 301 which is installed in front of the glass bead surface 207 and converts a solar light source into electrical energy, and the electrical energy supplied from the solar cell 301 are stored. To protect the lamp 301 and the glass bead surface 207 from external forces, and transmit the reflected light of the glass bead surface 207 to control the lighting of the lamp when necessary. The transparent window 205 fixed to the opening face of the housing 201 and a fixing panel 203 for fastening the transparent window 205 to the housing 201.

The control device includes a power storage unit 303 for storing electrical energy generated by the solar cell 301, a switch unit 309 for regulating the electricity stored in the power storage unit 303 to a reference voltage; The day and night are determined based on a light emitting unit 307 for emitting power energy supplied through the switch unit 309 and the supply energy of the solar cell 301, and the switch unit 309 is determined according to a determination result. It consists of a control unit 305 for controlling the turn-on.

On the other hand, the light emitting unit 307 may be used a light emitting diode or a high brightness light emitting diode device that can be turned on with a low power, a plurality of will be used. In the present invention, the light emitter 307 will be described as being on or off, but may be described as a blinking state having a predetermined period. This may be set according to the surrounding environment according to the installation place of the lane guidance device. For example, when the left turn section is an uphill road or a dangerous section at the intersection, the lighting of the light emitting unit 207 may be in a blinking mode to give an alert to the driver.

The lane guidance device configured as described above is installed in plural along the left turn (or right turn) lane of the intersection, and is buried on the road. In this case, of course, the housing 201 may be implemented in a circular shape so as to easily realize burial on the road. The buried lane guidance device protrudes from the fixed panel 203 and the transparent window 205 on the surface of the road, but as described above, the protruding portion is low so that the flow of the vehicle is not overwhelming.

The lane guidance apparatus converts a solar light source into electrical energy using the solar cell 301, and the converted electrical energy is stored in the power storage unit 303. The controller 305 detects the amount of electrical energy currently generated in the solar cell 301, and supplies the storage energy to the power storage unit 303 when the amount of electrical energy is greater than or equal to a reference value, that is, in the daytime mode. . On the other hand, the controller 305 turns on the switch unit 309 when it is determined that the amount of electrical energy generated by the solar cell 301 is equal to or less than a reference value, that is, in night mode.

The turn-on operation of the switch unit 309 is to supply the electric energy stored in the power storage unit 303 to the light emitting unit 307. The light emitting unit 307 uses a lamp having a predetermined brightness based on the stored voltage. Lights up. The light source of the lit lamp is scanned onto the glass bead surface 207, and the glass bead surface 207 reflects the light source in a predetermined direction. The driver of the left turn (or right turn) vehicle recognizes the reflected light source when turning left (or right turn).

Figure 4a is a view showing a state in which the lane guidance device according to the invention installed in the intersection. As shown, the lane guidance device is applied to the left turn lane in all directions except for the unprotected right turn. However, since the left-turning vehicle can only recognize the lane, the vehicle driver will not cause confusion due to the lane. For example, when a plurality of vehicles turn left according to a left turn signal as shown in FIG. 4B, the left turn vehicle recognizes only a left turn lane. This is because the reflected light of the glass bead surface 207 of the lane guidance apparatus looks at the left turning vehicle, and thus the lane guidance apparatus mounted in another lane is not recognized. In the above description, the lane guidance apparatus is applied as a left turn lane or a right turn lane of an intersection, but it may be applied to a straight lane of a road.

As described above, by incorporating all the left turn (or right turn) lanes in the intersection with the lane guidance device according to the present invention, the driver may recognize only the corresponding lane when driving the left turn (or right turn) vehicle. It has the effect of eliminating confusion and giving safety.

In addition, the present invention can prevent accidents by inducing a vehicle while the lamp is installed on the road surface in accordance with the signal when it is not easy to distinguish the lane because there is a problem in securing the visibility, such as night, fog day, rainy day. In addition, when driving at night, it is easy to recognize that the intersection is far away, and it is possible to prevent accidents by grasping the signal situation of the current intersection and entering it.

In addition, since the lane guidance apparatus according to the present invention does not protrude on the road, it does not interfere with traffic and does not cause damage to the device, thereby increasing the efficiency of the facility.
