Description

TECHNICAL FIELD [0001] The present invention relates to an optical fiber road sign,

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an optical fiber road marking incorporating reflective deposition, and more particularly, to an optical fiber road marking method of reflecting light on a road surface under a road surface, And a reflective deposition unit formed by depositing the other end of the optical fiber with a reflector so as to reflect the light incident on the light receiving unit of the optical fiber adjacent to the lid unit and to diverge the same to the light emitting unit of the optical fiber And the light receiving portion of the optical fiber whose one end is fixed to the cover portion of the lighting means and the light emitting portion are provided in the lane so as to face the direction opposite to the running direction of the vehicle. Thus, even if the visibility is unclear The light of the vehicle or surrounding is collected through the light receiving portion of the lighting means without the power supply of the lighting means The present invention also relates to an optical fiber road marking incorporating reflective deposition capable of allowing a driver to easily recognize a lane by reflecting the collected light to a light emitting portion by being reflected by a reflective vapor deposition portion.

Road sign "is a road attachment in accordance with Article 3 of the Road Law and Article 30 of the Regulation on the Structural and Facility Standards of the Road, which is followed by night or rainy weather. It refers to a sight guidance facility that complements the alignment of the road type road marking and clearly guides the driver's gaze to promote traffic safety and smooth communication.

Especially, it is more difficult for the driver to recognize the lane at night or rainy weather, which increases the probability of traffic accident.

Therefore, the road markers are properly installed in areas where the functions of the road marking such as the center line of the road, the lane boundary, the lane of the lane, the road obstacle and the safety zone are complemented and the driver needs to be aware of the linear induction or the change of the road environment, Roads that are not physically separated, roadway widths that are not physically separated, roadway widths, roadside edge sections, curved sections, tunnels, reduction / separation / confluence sections of lanes, change sections of corridors, traffic island, These folded bridges are representative of the installation section.

On the other hand, a general road marker is divided into a reflection type and a light emission type according to the driving method thereof, and the light emission type is further subdivided into a flicker type, a lighting type, and a switching type.

Among these, the reflective road marker does not have a self-luminous function and reflects the headlight of the vehicle to perform the corresponding function. Therefore, it is relatively inexpensive and easy to install. However, in order to realize a reflection surface at a predetermined angle, it is required to be installed so as to protrude from the road surface to a certain extent, thereby deteriorating road stability and running ability, and shortening the service life due to abrasion of the reflection surface.

On the other hand, the light-emitting road markers can emit light by incorporating a light source such as a light-emitting diode (LED). Therefore, it is advantageous in stability and driving ability because it can be buried in a pond so as not to be exposed from the road surface. However, since a separate power source device is required due to the characteristics of the LED, the structure of the road marking can be complicated.

Therefore, it is necessary to develop a road sign which can overcome the above disadvantages and improve the visibility of the lane at nighttime or in bad weather.

The optical fiber road marker incorporating the reflective deposition of the present invention is largely formed by including the marker body 100, the space portion 200, and the illumination means 300.

The marker body 100 is exposed on the road surface, and may be in the form of a disc, a square plate, and the like.

The space portion 200 is formed in a bowl shape and is buried below the road surface, and an upper surface provided below the epilayer body 100 is covered with the epilepoose body 100, and a certain space is formed therein .

The illuminating means 300 includes an optical fiber 310 cut in a predetermined length, a pedestal 110 to which one end of the optical fiber 310 is fixed, and a pedestal 110 installed on the pedestal body 100, And the other end of the optical fiber 310 is deposited by a reflector so as to diffuse the light incident on the light receiving portion of the adjacent optical fiber 310 to the light emitting portion of the optical fiber 310, (320).

Particularly, in the optical fiber road marker incorporating the reflective deposition of the present invention, the light receiving portion and the light emitting portion of the optical fiber 310, one end of which is fixed to the bearing 110 of the lighting means 300, So that the light of the vehicle captured by the light receiving unit of the optical fiber 310 is reflected by the reflection deposition unit 320 and emitted through the same light emitting unit as the light receiving unit of the optical fiber 310, .

The reflection deposition unit 320 reflects the light incident on the light receiving unit of the optical fiber 310 whose one end is fixed to the receiving member 110 and emits the light to the light emitting unit of the optical fiber 310, Or may be formed by vapor-depositing the cap 310 on the other end of the optical fiber 310.
