Abstract
The invention relates to a solar flashlight which is a product by perfectly combining a solar technique with an energy-saving LED (light-emitting diode). The appearance is exquisite and the function is practical. After the flashlight is placed in the sun at daytime, the flashlight can be used for several hours at night, batteries are not required to be changed, environmental pollution is not caused and the flashlight is a real low-carbon environmental-friendly product. The effect of saving resources can be promoted. All kinds of thin-film solar cell panels can be used on the flashlight.
Description
Technical field
The present invention is about a kind of solar energy equipment, particularly a kind ofly utilizes the transparent membrane solar cell to absorb light to convert electric energy to.And by the stabilizer transformation, driving the luminous flashlight of LED, the present invention can use various thin-film solar cell panels.
Background technology
Because the inexhaustible characteristic of solar energy, be subject to especially national governments attention and support.According to estimates, be about the earth on everyone consume one hundred ten thousand times by the energy that shines upon earth surface every year, that is to say, if take full advantage of centesimal solar energy, and the conversion efficiency with 10% is that it is converted to electric energy, can satisfy our demand.
No matter be present solar cell main flow--single polysilicon, or the thin-film solar cells that gradually grows up, its final target all is to want and can generate electricity by way of merging two or more grid systems, and substitutes present high pollution or high risk generation mode.
Solar cell has large-area lighting area, just can produce relatively a large amount of and operational electric energy, and therefore many factories utilize solar cell to replace deserted battery, uses the pollution that reduces environment.
Summary of the invention
Main purpose of the present invention is, a kind of flashlight with transparent membrane solar cell is provided, and its electric energy that utilizes the transparent membrane solar cell to produce is used allow flashlight luminous and reach the effect of power and energy saving.
To achieve these goals, according to a kind of flashlight with transparent membrane solar cell provided by the invention, in a plurality of thin-film solar cells of the outside laying of flashlight, thin-film solar cells can absorb or can reflects infrared light and the ultraviolet light wavelength of one at least, and the light that it absorbs is converted into electric energy uses and make flashlight luminous.
The present invention can also be applied to the following technical measures to achieve further.
Aforesaid a kind of flashlight with transparent membrane solar cell, wherein said thin-film solar cells can be the translucent thin-film solar battery, perhaps also can be light tight type thin-film solar cells.
Aforesaid a kind of flashlight with transparent membrane solar cell, wherein said thin-film solar cells has metal film layer, but infrared light and the ultraviolet light of this metal film layer reverberation in red.The metallic film layer material can be transition metal, comprises nickel. silver or aluminium.
For above-mentioned feature and advantage of the present invention can be become apparent, the below cooperates appended graphic being described in detail below.
