JP6389445B2 - Billboard sign - Google Patents

Description

  The present invention relates to a billboard sign with a daylighting function built in a solar battery for a building wall.

  Today, environmental protection on a global scale is being called out, and in the field of illuminated advertising signs, many light guide plate outdoor advertising signs, indoor advertising signs, etc. are installed in the premises and stores of station buildings.

  Further, a technique for charging a battery with electric power generated by a solar battery in the daytime by integrating the solar battery with a light guide plate and using the electric power for a ceiling lighting device at night is known in the following patent documents. This patented invention consists of a light transmissive plate laminated in the vertical direction, a solar panel that converts solar energy into electric energy, and a frame material that supports the two light transmissive plates and the solar panel. A roof structure with a lighting device comprising a battery for storing electrical energy converted by the solar panel, and a light source for illumination, wherein the solar panel comprises a light-transmissive backsheet, The light-transmitting plate member disposed between the light-transmitting plate members and the lower-side light-transmitting plate member is a roof structure with a lighting device configured by an edge-light type double-sided light guide plate that emits light from both upper and lower sides. .

Japanese Patent No. 5312259

  However, if solar panels or advertising signs are installed on the wall or opening of a building, indoor lighting is limited and the interior becomes dark.Therefore, in order to solve these problems, An object of the present invention is to provide a billboard sign with a built-in solar cell and a daylighting function that enables power generation, sign indication by a light guide plate, and daylighting indoors.

First, in the daytime, sunlight passes through the transparent glass plate and the glass light guide plate , and part of the light hits the photovoltaic cell and is converted into electric energy, and part of the light is converted into the photovoltaic cell and the sun. It passes through the transparent part between the photovoltaic cells and is taken into the room. (See Figure 2)

Secondly, the electric power generated by the photovoltaic power generation cell is supplied to the edge light LED installed at the edge portion of the glass light guide plate , and has an indication function as an advertising sign throughout the day and night. In addition, the electric power generated in the daytime is charged in a battery built in the lower frame material of the billboard sign, and becomes a sign light source for the billboard at night or in the rain. (See Figure 2)

Thirdly , the glass light guide plate is silk-printed with ceramic-based luminescent ink on the back side of the transparent glass plate, so that the light transmitted from the LED light source is emitted to the glass surface by reflection dots and the law of reflection and refraction. can do. Further, by controlling the density of the reflective dots, the entire gradation or partial light emission of the glass surface is possible. (See Figure 3)

Fourth, when the advertising medium of the glass light guide plate is replaced, or when the light emitting function is reduced such as a decrease in the illuminance of the edge light LED, in order to facilitate the replacement, as shown in FIG. The glass light guide plate sign unit is removed from the upper and lower outer frame members so that the structural sealant can be easily detached . ( Refer to Fig. 5 (a)->(b)->(c)-> (d) for the installation work process. Since the removal work process is the opposite, (d)->(c)->(b)-> (a )

  In the daytime, a part of the sunlight can be applied to the photovoltaic power generation cell to be converted into electric energy, and the other part can be taken into the room through the transparent part between the cells.

  The power generated by the solar power generation cell is supplied to the edge light LED, and the function as an advertising sign can be exhibited throughout the day and night.

The glass light guide plate can emit light, which has passed from the LED light source, onto the glass surface by the reflective dots.

The advertisement medium of the glass light guide plate can be easily replaced.
