Description

  The present invention relates to a self-luminous line-of-sight guidance sign that is installed mainly on the shoulder of a road or in a median strip and guides the line of sight of a driver of a vehicle.

  LEDs (light-emitting diodes) have a higher directivity of light rays than light bulbs, have a longer light-emission life, and require less maintenance. Therefore, LEDs (light-emitting diodes) have been used favorably for guiding the eyes of a vehicle driver at night. Many related inventions have been disclosed.

  For example, a light-emitting unit in which a plurality of LEDs are arranged, a flange projecting forward from above the light-emitting unit, and a housing that includes the light-emitting unit on the front side and stores equipment related to light emission of the LED. In a self-luminous line-of-sight guidance sign comprising a body and a solar cell module that generates electric power used for light emission of the LED, the upper surface of the buttock and the upper surface of the housing is a top surface that is a continuous surface, There is one in which the solar cell module is arranged on the upper end surface (Patent Document 1).

According to the self-luminous line-of-sight guidance mark, it is not necessary to separately provide the solar cell module by providing the solar cell module on the upper end surface formed by the upper portion of the collar and the casing. Moreover, since the line-of-sight guide top surface on which the upper end surface is located is the place where the light receiving efficiency of sunlight is the highest, high power generation efficiency can be secured without adjusting the angle of the solar cell module, and the angle of the solar cell module is maintained. A mechanism is not required, and operations related to formation and maintenance can be simplified. Furthermore, since the upper end surface is a continuous surface, an integrated planar solar cell module can be used, the solar cell module mounting work can be reduced, and the connection between the solar cell modules can be eliminated. This can lead to improved power generation efficiency.

  However, in the invention described in Patent Document 1, since the upper end surface has a horizontal shape, dust or the like tends to adhere to the upper end surface, that is, the surface of the solar cell module. If it does so, the power generation efficiency of a solar cell module will fall.

  In addition, the upper end surface including the flange portion has a horizontal plane shape, whereas the light emitting portion has a substantially circular shape and is different in shape, and thus the wrinkle effect is not sufficient.

  The present invention has been made to overcome the above-described problems, and an object of the present invention is to provide a self-luminous gaze guidance mark in which dust is not easily attached to the solar cell module provided on the upper end surface of the self-luminous gaze guidance mark. To do. Furthermore, an object of the present invention is to provide a self-luminous gaze guidance mark having a high wrinkle effect and good visibility.

  In order to achieve the above object, the present invention is configured as follows. That is, the self-luminous line-of-sight guidance mark according to the present invention includes a light-emitting portion in which a plurality of self-luminous bodies are arranged, and a housing that includes the light-emitting portion on the front surface side and stores equipment that emits light from the self-luminous body. A front surface portion of the upper end portion of the housing projects forward from above the light emitting portion to form a flange portion, and a curved surface in which the upper end surface of the housing including the flange portion is inclined downward in the left-right direction. The flexible solar cell module which has a shape and follows the phase shape is arrange | positioned at the said upper end surface, It is characterized by the above-mentioned.

  According to the self-luminous line-of-sight guide according to the present invention, since the upper end surface is not in a horizontal plane shape and is inclined downward in the left-right direction, dust or the like hardly adheres to the upper end surface, that is, the surface of the solar cell module. . Therefore, it becomes possible to maintain the power generation efficiency of the solar cell module high.

  In the self-luminous line-of-sight guide according to the present invention, it is preferable that the light emitting portion is substantially circular and the curved shape of the upper end surface is a curved shape along the upper end arc shape of the light emitting portion.

  In this way, the shape of the upper end surface including the flange portion is a shape along the outer peripheral shape (arc shape) on the upper side of the light emitting portion, so the wrinkle effect is enhanced.

  Furthermore, in the self-luminous line-of-sight guide according to the present invention, a protective layer is formed on the surface of the solar cell module, and a photocatalyst containing layer containing a photocatalyst such as titanium dioxide is formed on the outer surface of the protective layer. It may be. In this way, the surface is hydrophilized by the photocatalyst, so that contaminants such as dust and vehicle exhaust gas are more difficult to adhere, and even if it adheres, it is easily washed away by rain or the like and removed. As a result, contaminants are less likely to accumulate.

  As described above, according to the self-luminous line-of-sight guidance mark according to the present invention, the upper end surface is not a horizontal plane and is inclined downward in the left-right direction, so that dust or the like adheres to the upper end surface, that is, the solar cell module surface. Hard to do. Therefore, it becomes possible to maintain the power generation efficiency of the solar cell module high. In addition, by making the curved shape of the upper end surface of the self-luminous line-of-sight guide mark along the arc shape of the outer periphery of the light emitting portion, the wrinkle effect is enhanced and the visibility is improved.

  Furthermore, if a photocatalyst containing layer is formed on the surface of the solar cell module, contaminants such as dust and vehicle exhaust gas are more difficult to adhere.
