Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-luminous device for self-luminous display by covering the top of a pole such as a snow pole or a gaze guide.

[0002]

2. Description of the Related Art Heretofore, as a road marking body installed on a road shoulder, a median strip, or the like, for example, a pole such as a snow pole or a gaze guide is known. A reflection sheet is wrapped around the outer surface of the pillar, or a prism is attached to the upper end of the pillar as a reflector, and this snow pole or line-of-sight guidepost is used to receive the reflected light of the headlights at night to form the shoulder of the road or the median strip. I was aware. In addition, the reflective type may not receive retroreflected light depending on the irradiation angle of the headlight, and the visibility may not be sufficient in some places. Therefore, a self-luminous type with a built-in solar cell is installed. I have.

[0003]

However, since conventional pillars such as snow poles and gaze guides are originally designed to be clearly distinguished between a reflection type and a self-luminous type, solar cells and storage batteries are used. The self-luminous type, which is self-luminous when incorporated, is designed to fit directly into the snow pole or the line-of-sight guidance sample and function. However, there is a detachable structure that can be repaired on site when the self-luminous part is broken down or loses its function due to mischief, and is adapted for maintenance and repair. Therefore, for those newly installed, the self-luminous type is appropriately selected and used as needed, but it is easy to add the self-luminous performance to the reflective type already installed in large numbers. Instead, a method of additionally installing or replacing a self-luminous type has been adopted. That is, it is desired that the driver can switch to the self-luminous type, which has a higher nighttime visual recognition effect, in a place where the driver particularly wants to increase the gaze guidance, or in a line where traffic volume is rapidly increasing or in a zone where traffic accidents frequently occur such as a snowy season. ing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has improved light-guiding effect to a driver by adding a self-luminous function to a pillar more easily, or by attaching it to a required snowy season, thereby improving traffic safety at night. It is intended to provide a self-luminous device that can contribute to the countermeasures.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, at least a solar cell unit including a solar cell, a controller, and a storage battery and a luminous body are housed in a cap and electrically operated to emit light. Thus, a self-luminous device is manufactured in which an insertion concave portion is provided in a lower portion of a cap body and can be detachably mounted on an upper end of a column.

[0006] The solar battery unit is charged with a storage battery in response to daytime sunlight, and has a function of turning on and off the illuminant by a controller at night, and having an adjusting function of keeping on or off. Further, even if a capacitor is mounted on the solar cell unit and stored in a warehouse for a long time, and the self-luminous device of the present invention is installed later, consideration is made so that the self-luminous performance is restored.

Further, in the self-luminous device of the present invention, a solar cell is arranged in an upper layer inside a transparent tubular cap, a horizontal plate is arranged at a lower layer with a space therebetween, and a plurality of LEDs are arranged on a peripheral edge of the horizontal plate. And a concave curved surface is formed to face a portion from which light is transmitted through the cylindrical body substantially horizontally from the LED.
The ED emits light, refracts and diffuses on the concave curved surface, and emits light over the entire circumference. In this manner, the light points are connected to form a large surface so that the light can be visually recognized. In addition, the solar cell is mounted so as to close the upper end surface of the cylindrical body,
Alternatively, it may be arranged so that the south surface is oriented in the cap body, and even if the upper surface is closed by snow, electricity may be stored, and the shape, material, and angle of the solar cell are not limited.

Further, the number of LEDs may be determined efficiently by setting the power receiving capacity, power storage function, lighting discharge time and the like of the solar cell, and the LEDs are evenly arranged on the horizontal plate. In addition, LED
May be flashed in consideration of power consumption.
The outer peripheral surface of such a light emitting LED is formed by a transparent cylindrical cap so that light is emitted over four circumferences. Further, the transparent cylinder is formed in a lens structure facing the LED in order to more effectively increase the light emission amount of the LED, and such a lens structure is considered so that the point light source of the LED can be visually recognized by the surface light source. I have.

Further, the rubber elastic body is in contact with the inner wall surface of the insertion concave portion, and when the rubber elastic body is inserted into the column, the rubber elastic body contracts and press-fits with the outer wall surface, so that the rubber elastic body hardly comes off.
Further, when the rubber elastic body has a saw-tooth cross-sectional shape, for example, an elastic body that is easy to enter and hard to remove can be obtained by utilizing the rebound resilience. Note that the rubber elastic body may be an O-ring or a belt-like shape, but a hardness having a small deformation amount and a large repulsive force when narrowly provided in the gap may be appropriately selected. On the other hand, it is necessary to make these rubber elastic bodies easy to remove, for example, by making a curved plate along the outer surface of a snow pole as a support as a removal tool and inserting it into the gap so that it can be easily removed together with the tool. To

The mounting structure of the self-luminous device of the present invention is not limited to the rubber elastic body, but may be a method of fastening with a binding band from the outside of the insertion concave portion, or screwing into a ground snow pole with a plurality of screws. A method in which the inner wall of the insertion recess is fixed or a spiral projection is formed on the inner wall of the insertion recess and the screw is pressed in from the upper end of the snow pole, and the method is not particularly limited.

[0011]

The storage battery is charged by the sunlight shining on the solar battery during the daytime, and at night or during snowfall, the storage battery is used as a power source to start lighting by the controller. The LED is provided around the inside of the transparent cap, and is transmitted through a concave lens formed on the peripheral wall of the cap facing the LED, refracted and diffused, and emits light over four rounds.
Such a series of operations is performed by the self-light-emitting device itself mounted on the upper end of a snow pole or the like, and the self-light-emitting function is immediately added by attaching to a reflection-type snow pole that does not emit light. In addition, even if the battery is removed for a long time and deeply discharged, the self-luminous performance is restored by the capacitor.

[0012]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an elevational perspective view of the present invention mounted on a snow pole. FIG. 2 is a partially enlarged sectional view of FIG. FIG. 3 is a plan view seen from the AA cross section direction in FIG. 2, and FIG. 4 is a partially enlarged cross sectional view of FIG.

First, in FIG. 1, a main body 1 of the present invention is mounted on the upper end of a snow pole 2, and a reflection sheet 21 is wound around the abdomen of the snow pole 2 to provide day and night visibility. .

FIG. 2 is an enlarged view showing a state in which the main body 1 of the present invention is mounted on the snow pole 2. The solar cell 4 is fixed to the upper end of the center support rod 31 of the transparent cap body 3 so as to face upward. A horizontal plate 5 is provided at a lower portion, and a plurality of LEDs 6 are provided at an edge thereof. In addition, a condenser 7
However, the controller 8 and the storage battery 9 are further controlled and electrically connected to each other. Further, an insertion recess 32 into which the upper end of the snow pole 2 can be inserted is provided in the lower part of the cap body 3, and a rubber elastic body 33 is abutted on the side wall to allow the snow pole 2 to be inserted.
The upper end is crowned.

The cap body 3 may be all transparent and may be integrally molded, but at least within the light receiving angle of the solar cell 4 and the irradiation angle of the LED 6, a transparent glass or molded article of polycarbonate resin, acrylic resin, MMA resin or the like is used. The lower part of the cap body, which contains the storage battery 9 and the like, is molded with an opaque resin or the like and is integrated with the upper transparent body.
The cap body is waterproofed so that rainwater or the like does not enter and the electric system is not broken.

FIG. 3 shows that the LEDs 6 are evenly arranged on the peripheral edge of the horizontal plate 5 and that a concave curved surface 34 is provided on the wall surface of the cap body 3 facing each LED 6 so as to function as a lens. FIG. 4 shows a refraction state of light emitted from the LED 6, and L
The light emitted from the ED 6 forms a concentric concave surface 34a from the light emitting axis so that the light is absorbed by the inner wall surface of the cap body wall surface,
The concave curved surface 34b is formed so that it is refracted and diffused on the outer wall surface and connected to an adjacent LED light beam at a distance of 50 m. The concave curved surface may be formed in a circular shape on the wall surface of the cap body 3 or may be formed in a vertical groove shape. Alternatively, a concave curved surface in a polka dot pattern may be provided on the entire wall surface. Therefore, as described above, the weak light of each LED is enhanced by making use of the lens effect so that the LED can be visually recognized from a distance.

On the other hand, the rubber elastic body 33 sandwiched between the upper side walls of the snow pole has a saw-toothed cross-sectional shape, and is selected to have a material hardness such that it can be easily inserted by press-fitting and is difficult to come off. Uses a special tool to release the rebound resilience. If the insertion portion is shallow and wobbly, it can be appropriately deepened, or banding or screwing from outside may be used together.

[0018]

According to the present invention, at least a solar cell unit composed of a solar cell, a controller and a storage battery and a luminous body are housed in a cap, electrically function to emit light, and are inserted under the cap. Since the recess is provided and it is easily and detachably attached to the upper end of the column, on routes where traffic volume has increased rapidly or in areas where traffic accidents frequently occur during snowfall,
By attaching to an existing snow pole or the like, night visibility can be improved, traffic accidents can be prevented, and the cost for adding functions can be reduced.

In addition, the self-luminous device of the present invention is always attached to emit light by itself, and may be detached and stored again in a warehouse as needed, so that a capacitor for storing electricity even if deeply discharged is used. It is provided so that the self-luminous performance is restored.

Further, since a structure is employed in which the light of the light emitting LED is efficiently radiated to a distant place and over the entire periphery by the lens function of the transparent cap side wall, the light can be visually recognized regardless of the installation location. .
