Abstract

PROBLEM TO BE SOLVED: To provide a solar charging method which improves charging efficiency by being attached with condensing convex lenses. SOLUTION: In the solar charging method which improves charging efficiency by being attached with the condensing convex lenses, a solar panel unit is constituted by providing a proper quantity of the protrusions of the condensing convex lenses to a solar panel, and a transmissive and flat material to be attached at a position of 1/2>= focal distance of the protrusions in the form of the convex lenses on the front side of the solar panel. By positioning the protrusions at the position of 1/2>= focal distance in consideration of temperature raising during charging on the front side of the solar panel, and condensing in a range wider than usual by attaching the convex lenses like this, and since the convex lenses are in shapes of protrusions, an allowable range is large also in the incident angle of sunlight to improve condensing property to improve charging efficiency. In addition, air vents are formed at the transmissive and flat material to help heat radiation, and a solar fan is attached to the solar unit for sending air to prevent the temperature of the solar panel from being raised, to improve charging efficiency.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar charging method in which a convex lens having a light converging property is attached to improve charging efficiency.

[0002]

2. Description of the Related Art When a solar panel is used to charge by sunlight or the like, the amount of charge varies depending on weather conditions. It sometimes ended with the usage time of.

[0003]

When such a situation occurs, for example, in the case of a garden light or a street light, the lighting time becomes short, which causes a problem that it is not good for crime prevention. Also, in the case of road marking lights, the lighting time is short, the illuminance becomes dark,
There was also a problem that it was dangerous for safety. Further, if the solar charging is insufficient, the power source equipment as a standby power source must be considered as the main power source, and the original purpose of the solar charging is lost.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a solar charging method in which a convex lens having a light-collecting property is attached to improve charging efficiency.

[0004]

In order to achieve the above object, a solar panel unit is a solar cell of a single crystal silicon cell in a solar charging method which is equipped with a convex lens having a light-collecting property according to the present invention to enhance charging efficiency. Solar cells such as batteries and hybrid solar cells (HIT) and a transparent plate-shaped material are provided with an appropriate number of convex lens-shaped projections having light-collecting properties, and the convex lens-shaped projections on the front side of the solar panel. It is characterized in that it is configured to be attached to a position with a focal length of 1/2 or less. According to this mechanism, for example, on the front side of the solar panel, the focal length of the convex lens-shaped protrusion is 1/2 in consideration of the temperature rise during charging.
It is located at the following position, and by being attached in this way, it collects light in a wider range than usual, and since the convex lens has a protruding shape, it has a wide allowable range even at the incident angle of sunlight, Therefore, the charging efficiency can be improved.

It is possible to increase the light-collecting property and further improve the charging efficiency. In addition, since the convex lens has a projection shape, the allowable range is wide even at the incident angle of sunlight, the light-collecting property can be enhanced, and the charging efficiency can be further enhanced.

Next, the operation of the solar unit S according to this embodiment will be described. FIG. 4 shows a state of the transparent plate-like material 2 with the convex lens-like protrusions engaged with the solar unit S.
