It has become. The transparent portion 51a is made of a transparent plastic resin such as acrylic or polycarbonate, tempered glass, or the like. In the present embodiment, the attachment portion 51b is also integrally formed from the same material (plastic resin) as the transparent portion 51a and is transparent. However, the attachment portion 51b is not necessarily transparent, for example, the attachment portion The vicinity of the hole 53 may be strengthened by forming 51b from metal (steel or the like), or by laminating a metal plate on the base of the curved transparent hood body 51 to serve as the attachment portion 51b.

(Double-sided light receiving solar cell 6)
A double-sided light-receiving solar cell 6 of the double-sided light receiving type is mounted on the surface of the transparent portion 51a of the curved transparent hood body 51 on the signal lamp device 3 side (hereinafter also referred to as an inner surface). The double-sided light-receiving solar cell 6 is composed of a flexible sheet-like double-sided light-receiving solar cell 61 formed in a flexible sheet shape. As shown in FIG. 2, the light L1 from the signal lamp 3 is received by the inner side surface 61x to generate power. In addition, power is generated by receiving sunlight L2 transmitted through the transparent portion 51a on the opposite surface 61y (hereinafter also referred to as an outer surface).

  The flexible sheet-like double-sided light-receiving solar cell 61 includes a transparent (colorless and transparent) substrate sheet (not shown), a double-sided light-receiving cell provided on the substrate sheet, and a protective sheet covering the surface. As the material of the substrate sheet, transparent and bendable polyimide (polyalicyclic polyimide) is used. The double-sided light-receiving cell is black or brown and can block a certain amount of light. As the double-sided light-receiving cell, one having the same photoelectric exchange efficiency on both sides, or one having a different photoelectric exchange efficiency between one light-receiving surface and the other light-receiving surface may be used. The protective sheet is made of a transparent plastic that can be bent. On the surface of the protective sheet, a photocatalyst may be carried by an adhesive or the like in order to oxidize and decompose dirt (organic matter, nitrogen oxide, chloride compound, etc.).

  Such a flexible sheet-like double-sided light-receiving solar cell 61 is curved in accordance with the inner surface of the transparent portion 51a of the curved transparent hood 51, and is attached to the inner surface of the transparent portion 51a with an adhesive, a double-sided tape, or the like. .

The electric power generated by the flexible sheet-like double-sided light receiving solar cell 61 is charged to the rechargeable battery installed in the column where the signal device 2 is attached or in the vicinity thereof, and the signal lamp 3 of the signal device body 4. Is used as a power source for operating the control device that controls the flashing of the signal lamp 3 and the power source for lighting the lamp. The power used for the traffic signal body 4 such as the signal lamp 3 and the control device is supplied from the commercial AC power supply in addition to the above-described rechargeable battery, and the power generated by the double-sided light receiving solar cell 6 is insufficient for the commercial AC power supply. Is to be supplemented by. Further, when the commercial AC power supply is interrupted due to a power failure at the time of a disaster or the like, the traffic signal body 4 is operated for a certain period of time by the electric power stored in the rechargeable battery.

(Action / Effect)
As shown in FIG. 2, the traffic light hood 1 attached to the traffic light body 4 as a fence for the traffic light 3 (a rain avoidance, a sunshade fence) includes a transparent hood body 5 having a transparent portion 51 a, and a transparent hood body 5. And a double-sided light-receiving solar cell 6 mounted on the inner surface of the transparent portion 51a. The transparent hood body 5 functions to avoid rain and snow with respect to the signal lamp 3, and the double-sided light receiving solar cell 6 attached to the transparent portion 51a of the transparent hood body 5 has a cell portion as described above. Since it is black or brown, it functions as an awning for the signal lamp 3.

  The double-sided light receiving solar cell 6 receives the light L1 from the signal lamp 3 by the inner side surface 61x and generates power, and also generates power by receiving sunlight L2 that has passed through the transparent portion 51a of the transparent hood body 5 on the outer side surface 61y. To do. That is, by attaching the signal device hood 1 according to the present embodiment to the signal device main body 4 as a cage of the signal light device 3, both the light L1 and the sunlight L2 of the signal light device 3 can be obtained without additionally installing a solar cell. Can generate electricity. As a result, stable power generation by the light L1 of the signal lamp 3 in the weather and time zone where sufficient sunshine such as rainy weather, cloudy weather, and nighttime cannot be expected, and sufficient power generation according to the amount of sunlight by the sunlight L2 in fine weather It can be realized at low cost and space saving.

  Since the double-sided light-receiving solar cell 6 is attached to the inner side surface of the transparent hood body 5, the transparent hood body 5 protects it from wind and rain, and suppresses damage and deterioration. Further, the double-sided light receiving solar cell 6 attached to the inner side surface of the transparent hood body 5 transmits the light L1 of the signal lamp 3 having a light intensity (illuminance) smaller than that of sunlight L2 in fine weather through the transparent hood body 5. Can receive light directly. Therefore, attenuation due to the light L1 of the signal lamp 3 passing through the transparent hood 5 does not occur, and the power generation efficiency by the light L1 of the signal lamp 3 can be increased as much as possible. In addition, since the signal lamp 3 lights up one after another in order of blue, yellow, or red, the solar cells 6 respectively attached to the inner side surfaces of the hood 1 of the signal lamp 3 of each color continuously Power generation with stable high power generation efficiency becomes possible.

  When the solar cell 6 having different photoelectric exchange efficiency is used on both sides, the surface with high photoelectric exchange efficiency may be used as the inner side surface 61x. Thereby, the light L1 of the signal lamp 3 weaker than the sunlight L2 can be received on the surface with high photoelectric exchange efficiency, and the power generation efficiency by the light L1 of the signal lamp 3 at the time of rain or night can be further increased. However, if importance is attached to power generation by sunlight L2 in fine weather, the surface with high photoelectric exchange efficiency of the double-sided light-receiving solar cell 6 is defined as the outer surface 61y.

  Further, the yellow signal lamp 3 is extremely short in lighting time compared to other colors, and power generation by the light L1 from the signal lamp 3 cannot be expected. Therefore, in the traffic light hood 1 attached to the yellow signal lamp 3, it is conceivable that the surface with high photoelectric exchange efficiency of the double-sided light-receiving solar cell 6 is the outer surface 61y, and power generation by sunlight L2 is emphasized. In this case, in the traffic light hood 1 attached to the red / blue signal lamp 3, the surface with high photoelectric exchange efficiency of the double-sided light receiving solar cell 6 is the inner side surface 61x, and power generation by the light L1 of the signal lamp 3 is emphasized. May be.

  The transparent hood body 5 is a curved transparent hood body 51 that is curved so as to have at least the upper part of the signal lamp device 3. As a result, the flexible sheet-shaped double-sided light receiving solar cell 61 attached to the inner side surface of the curved transparent hood 51 has an irradiation angle of sunlight L2 of one day as shown by a dashed line arrow in FIG. Even if it changes through, sunlight L2 can be received at an appropriate angle (an angle close to a right angle) at any part.

  The double-sided light-receiving solar cell 6 uses a flexible sheet-like double-sided light-receiving solar cell 61 formed in a flexible sheet shape. Since the flexible sheet-like double-sided light receiving solar cell 61 is made of plastic or the like, it is lighter than a normal solar cell using glass. Therefore, the load burden when the traffic signal hood 1 is attached to the traffic signal body 4 is reduced.
