Benefits of technology

[0008]The present invention has been made in view of the above problems, and it is an object of the present invention to provide a light emitting road boundary stone using a solar cell, which can achieve not only an improvement in installation workability but also ease in repair and management after installation.
[0009]It is another object of the present invention to provide a light emitting road boundary stone using a solar cell, which can achieve an improvement in shock-resistance, can effectively prevent moisture from infiltrating a solar cell unit having an electric circuit on rainy or snowy days, and can improve not only clear visibility of images added thereto at any time of day or night, but also the brightness of a light emitting unit, whereby enhanced safety of pedestrians and automobile drivers can be accomplished.

Problems solved by technology

However, the marble or cement made boundary stones are not easily visible to automobile drivers or pedestrians at night due to their material characteristic.
However, a problem of this solution is that the attached reflective sheet tends to become detached by itself after a while or suffers from deterioration in reflective performance, and therefore still exhibits the above-described problem of the conventional boundary stones.
Furthermore, detachment of the reflective sheet results in a poor outer appearance of the boundary stone.
However, the Utility Model registered by the applicant of the present invention reveals several problems.
That is, it is difficult to repair and manage after installation.
Further, through-holes must be perforated through a body of the boundary stone at upper end locations to install the light emitting units at opposite side surfaces of the body, and therefore, the boundary stone always has a great risk of being easily damaged by external shock caused, for example, upon an automobile crash.
Similarly, in the case of the traversal boundary stone, an upper surface front edge thereof is somewhat sharply formed, and therefore, may be easily damaged by external shock caused upon an automobile crash.

first embodiment

[0023]As shown in FIGS. 3 and 4, the boundary stone 10 in accordance with the present invention is a type conventionally referred to as a bollard. The boundary stone 10 includes a rectangular column shaped body 20 having a predetermined height. The rectangular column shaped body 20 is formed at the center of an upper surface thereof with a solar cell unit mounting recess 28, such that at least one solar cell unit 30 is mounted in the mounting recess 28 in accordance with a light receiving ability thereof. Also, the body 20 is formed at opposite lateral vertical or inclined surfaces thereof with a pair of light emitting unit mounting recesses 27 having a predetermined depth, such that a pair of light emitting units 50 are inserted into the mounting recesses 27, respectively. Each of the light emitting units 50 has a light adapted to be turned on / off upon receiving electricity from the solar cell unit 30. Wiring bores 25 are penetrated between the solar cell unit mounting recess 28 fo...

second embodiment

[0044]Meanwhile, in the case of the bollard type boundary stone associated with the present invention, the light emitting unit mounting recess 27 is formed at the edge of the body 20 by processing a minimized region of the body 20, rather than processing the overall interior of the body. This has the effect of preventing the boundary stone from being damaged even when a relatively great external shock is caused by an automobile crash. Also, the horizontally elongated rectangular boundary stone features the inclined surface 22 at the edge of the upper surface of the body 20. This results in a less risk of damage even when the boundary stone collides with an automobile. In particular, due to the fact that the high-brightness reflective sheet 60 to reflect light from an automobile is separately formed from the transparent acryl plate 52, and is attached to the translucent acryl plate 55, which is located behind the transparent acryl plate 52, even if the outermost transparent acryl pla...

Abstract

Disclosed herein is a light emitting road boundary stone using a solar cell. More particularly, the light emitting road boundary stone includes a body, a solar cell unit mounted in an upper surface of the body and having a solar cell plate, a battery, and a circuit unit, and one or more light emitting units mounted in one or more lateral surfaces of the body and having lights to be turned on / off based on electricity supplied from the solar cell unit and other control conditions. The solar cell unit includes a lower fixing case embedded in the body of the boundary stone and an upper fixing case separably assembled to the lower fixing case. The light emitting road boundary stone has advertisement and propaganda functions, in addition to its essential delimitation function, via displaying images at any time of day or night.

Description

TECHNICAL FIELD[0001]The present invention relates to a light emitting road boundary stone using a solar cell, and more particularly, to a light emitting road boundary stone using a solar cell, which is installed at a boundary between a roadway and a sidewalk, a separator in a sidewalk, a parking place, a traffic island, or the like, and is adapted to accumulate sunlight in the daytime and convert the accumulated sunlight into electric energy to emit light at night, the light emitting road boundary stone containing special symbols or images to have advertisement and propaganda functions, in addition to its essential delimitation function, via displaying images at any time of day or night, whereby safe driving of automobile drivers and protection of pedestrians can be accomplished.BACKGROUND ART[0002]Generally, boundary stones are mainly used to separate a roadway from a sidewalk. In these days, the boundary stones are also used at a boundary portion of a traffic island, which is ins...
