Abstract

The present invention relates to a guardrail, and in order to secure an existing guardrail or a guardrail assist device, the present invention uses a property of an optical fiber shown only at a point where light is terminated from a starting point, The light passing through is reflected irregularly, thereby realizing a guard rail or a guard rail assist device.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a laser safe guardrail using a fiber-

The present invention relates to a guardrail, and is a safeguard rail suitable for the nature of an optical fiber and the role of a guardrail.

(EN) A light emitting structure unit using an optical fiber. (EN) A light emitting structure unit using an optical fiber. An optical fiber bundle having a plurality of optical fibers corresponding to the number of the through holes so that the light introduced from one end of the structure having a plurality of through holes is emitted through the corresponding through hole, And a light source for applying light to the optical fiber.

Roads through countryside or through mountains are covered with rice fields and cliffs outside the roads. The fence is installed on the outside of these roads. However, there are traffic accidents that happen due to the darkness of the day, even if you turn on the light at night. Also, the luminous stickers and street lamps installed at regular intervals on the road can not be installed tightly because they are expensive to install and maintain.

Using the property of the optical fiber seen only at the point where the light ends from the starting point, the problem is resolved by diffusing the light passing through the groove at a certain interval through the middle of the guardrail.

With this invention, when a streetlight such as a mountain road, a cliff-top road, or a country road is not installed in a dense manner, or when the road is darkened on an uninstalled road, light strikes the acrylic fence at regular intervals along the fence. It is more economical than street lamps because it can visually prevent accidents and uses less electricity from lasers, and is more efficient than luminous stickers attached at wide intervals.

1 is a schematic diagram of the present invention.

Acrylic tube is arranged by the principle of optical fiber according to the road fence. Then, a groove is formed at an equal interval in the acrylic tube so that light can be emitted from the grooved portion when the light passes through the acrylic tube. In order to secure the disadvantage of the laser beam which is caught in the acrylic tube which can not reach more than 3km, the laser is installed at regular intervals to complete the safeguard rail.
