Referring to FIG. 5, the illustrated embodiment includes a photovoltaic power supply unit 250 as a power supply unit of a transparent soundproof wall for display and display.

Solar light is a useful renewable energy source, and interest in this has recently increased. In the present invention, it is provided as an apparatus for generating electric power required for a light source.

As shown, the present embodiment includes a photovoltaic module 251 that is disposed on the upper end of the holding member 110 to collect sunlight. In particular, the photovoltaic module 251 herein does not need to be limited to a particular form, and it is noted that the illustrated shape is a preferred example.

The photovoltaic module 251 is a form in which a plurality of solar cells are connected in series and in parallel and may be referred to as a solar cell unit. The photovoltaic module 251 focuses sunlight to output the necessary DC power. And the DC power output here is boosted in the form necessary for the output of the light source in the converter 252.

The photovoltaic power supply unit 250 collects sunlight during the day to generate electricity to charge the solar power storage battery. Then, the light emitting module 141 is turned on by using the power stored in the solar power storage battery at night or whenever necessary. As a result, front light diffusion occurs through the light diffusion member 137 to implement visual information to the section user.

And a wind power generation module 351a connected to the shaft of the blade rotated by the wind to output power. Here, in the case of the blade and the wind power generation module, since the power is output only when the wind blows, the blade and the wind power generation module may further include a sensing means for detecting the strength of the wind. The wind speed sensor 351b may be further included. .

The wind speed sensor 351b detects the strength of the wind blowing toward the wind power generation module 351a, in particular toward the blade 351. The wind power generation module 351a may be electrically connected to operate the wind power generation module when the detected wind intensity is greater than or equal to a reference value.

Looking briefly at the operation relationship of the wind power generator 350, when the strength of the wind detected by the wind speed sensor is more than the reference value capable of generating wind power, the wind power generation module is operated at all times to output power. The output power is stored in the wind power storage battery, and the power stored in the wind power storage battery is applied to the light emitting module 141 again at night or whenever necessary to exert a lighting effect. As a result, front light diffusion occurs through the light diffusion member 137, and the section user can recognize useful visual information.

On the other hand, even in the case of the wind power generator 350, when the stored power is exhausted, or when the solar power generation is not smooth (for example, rainy weather), an external commercial power can be further used. The auxiliary power supply 360 may be further provided.

On the other hand, the outer surface of the transparent panels 131, 133 according to the present invention, a transparent material may be further provided with a protective coating layer formed for the purpose of improving the strength.
