Summary of Invention Technical Problem
[5]
However, in the devices disclosed in PTL 1 and PTL 2 a distance between the fluorescent lamp tube and the solar panel is equal to or greater than 15 mm. Therefore, even if a high-intensity fluorescent lamp tube is used and a solar panel with a large area is employed, little practical electromotive force is obtained.

[6]
On the contrary, the Applicant of the present application has proposed a power-generating lamp which comprises; a linear or annular lamp tube that emits light by turn on the electricity; a solar panel that has a cross section of an arc band-like shape having a length within a range which is equal to or less than the total longitudinal length of the lamp tube or equal to or less than the circumferential length and equal to or greater than the total longitudinal length of a low-temperature region of the lamp tube or equal to or greater than the total circumferential length of a low-temperature region of the lamp tube and having a width within a range which is equal to or greater than 1/5 of the outer circumference of the lamp tube cross section and equal to or less than 1/2 thereof, and receives light from a rear side of the lamp tube and generates an electromotive force; a transparent heat-resistance layer that is stacked on a light-receiving surface of the solar panel and that is disposed behind the lamp tube so that the transparent heat-resistance layer is attached to the rear side of the lamp tube or the light-receiving surface has a distance of 10 mm or less from the rear side of the lamp tube; and a power supply line that outputs the electromotive force of the solar panel, in which electric energy of illumination can be effectively used to generate a sufficient electromotive force ( PCT/JP2011/59364 JP2011059364W ).

[7]
However, the abovementioned power-generating lamp is produced as a completed product and is provided to markets by a manufactory. User has to purchase the power-generating lamp as a completed product and has to replace an existing fluorescent lamp or LED lamp with the power-generating lamp.

[8]
Therefore, if the user can simply attach a solar panel to an existing fluorescent lamp or LED lamp in a house or a store to construct a power-generating lamp, then spreading of the power-generating lamp can be expected.

[9]
The present Invention is made in consideration of the abovementioned circumstances and an object thereof provides a solar panel device which can be simply attached to an existing fluorescent lamp or LED lamp to construct a power-generating lamp.

Solution to Problem
[10]
Therefore, according to an aspect of the present Invention, there is provided a solar panel device which is attached to a lamp tube of a linear fluorescent lamp having high-temperature regions on both sides and a low-temperature regions between the high-temperature regions, or to a lamp tube of a linear LED lamp having a low-temperature region as a whole to construct a power-generating lamp which comprises:
one or more solar panels that have an cross section of a arc band-like shape, have an arc length in range which is equal to or greater than 1/5 of an outer circumference of the cross section of the lamp tube and equal to or less than 1/2 of the outer circumference in a width direction, receive light from a rear side of lamp tube and generate an electromotive force; a power supply line that outputs the electromotive force of the solar panel; and a tubular base holder that has a tube shape, has the solar panel attached to an inner surface or an outer surface thereof longitudinally, is externally fitted to the lamp tube to cover the lamp tube, holds the solar panel so that a light-receiving surface of the solar panel comes into contact with the surface of the lamp tube or is located with a gap of 10 mm or less from the surface of the lamp tube.

[11]
One embodiment of the present Invention is that a solar panel having the cross section of the arc band-like shape is attached to the tubular base holder and the lamp tube of a fluorescent lamp or an LED lamp, covering with the tubular base holder, so that a part or all of the light-receiving surface of the solar panel are in close contact with the lamp tube or the light-receiving surface of the solar panel, face the lamp tube with the distance of 10 mm or less from the surface of the lamp tube. Accordingly, it is possible to secure the sufficient electromotive force of the solar panel and to construct a power-generating lamp by only covering a lamp tube of an existing illumination lamp with the tubular base holder, thereby expecting of a larger spreading of the power-generating lamp.

[12]
The magnitude of the electromotive force of the solar panel is inversely proportional to the square of a distance from a light source. In the present Invention, the distance between the light-receiving surface of the solar panel and the lamp tube is 10 mm or less, which is smaller then in PTL 1 and PTL 2, thereby generating the large electromotive force by the use of the solar panel.

[13]
When the solar panel uses a flexible substrate such as a film substrate, the solar panel can be extended in order to be flat during a transporting and can be bent to the arc shape of the cross section during a using. However, when the solar panel utilizes a solid substrate such as a glass substrate, a plastic substrate, or a metal substrate, it is necessary to bend the solid substrate to the arc band-like shape of the cross secti…
