Cultural display device using thin-film solar cells on luminous plastic billboards

Abstract

The invention relates to a cultural display device with a thin-film solar cell applied to a light-emitting plastic advertising board, and belongs to the technical field of new energy power generation culture. Due to shielding of atmospheric brown clouds in the air and haze on the ground, solar radiation received on the ground is already reduced by 4%, electric energy production of the thin-film solar cell mounted on the advertising board on the ground is reduced, and power supply to a display screen is affected. The electric energy production of the thin-film solar cell can be increased by light emitted from the light-emitting plastic advertising board produced from long-lasting light-emitting materials and light reflected by LED lamps and sunshine, current outputted from the thin-film solar cell is inputted into controllers through an electric lead to be adjusted, current outputted from the controllers is supplied to the LED lamps through the electric lead and LED lamp conducting frames for lighting, and current outputted from the controllers is supplied to the display screen through the electric lead. Current outputted from lithium ion batteries is supplied to the display screen and the LED lamps respectively through the electric lead, photosensitive self-control switches and the controllers.

Description

technical field [0001] The invention relates to a cultural display device in which thin-film solar cells are applied to luminous plastic billboards, and belongs to the technical field of new energy power generation culture. Background technique [0002] At present, there are two evil things on the earth that affect and attenuate the solar radiation received by the earth's surface, gradually darken the whole world, and affect the survival and development of human beings on the earth. [0003] One evil thing is atmospheric brown clouds in the sky. At the end of the last century, scientists discovered an air pollution belt with a thickness of about 3 kilometers and an area of ​​more than 9 million square kilometers over the Indian Ocean. This air pollution belt appeared in brown on the satellite cloud image. Later, it was discovered that there were brown atmospheric air over many places in the world.

Problems solved by technology

At the end of the last century, scientists discovered an air pollution belt with a thickness of about 3 kilometers and an area of ​​more than 9 million square kilometers over the Indian Ocean. This air pollution belt appeared in brown on the satellite cloud image. Later, it was discovered that there were brown atmospheric air over many places in the world. Clouds, Atmospheric brown clouds over the globe contain particulate pollutants from the burning of fossil fuels and biomass fuels since the Industrial Revolution, including aerosol black carbon, organic carbon, sulfates, dust, nitrates, and Ammonium salt and other components, atmospheric brown clouds absorb and scatter solar radiation in the air, so that the thin-film solar cells installed on the billboards on the ground reduce the power generation of thin-film solar cells due to the reduction of direct sunlight radiation, affecting The amount of power supplied to the display screen on the billboard is reduced, so that tourists cannot clearly see the content of cultural display calligraphy and painting advertisements displayed on the display screen

[0004] Another evil thing is the smog above the ground. Among the 31 days in January 2013, the weather in Beijing had smog on 27 days, and only 4 days were sunny (the daily average value of PM2.5 was 35 μg / m3) , the root causes of smog are coal burning, industrial pollution, motor vehicle emissions, dense urban population, etc. In September 2013, the number of smog days in Beijing was nearly four times that of normal years. Tianjin, eastern Shanxi, north and west of Shanxi, Guanzhong area of ​​Shaanxi, northern Henan and other places had moderate haze, and some areas had severe haze. On December 8, 2013, North China, Huanghuai, east of Southwest China, most of Jiangnan and parts of South China The smog in the area is connected together, and the smog blocks the radiation of sunlight, so that the thin-film solar cells installed on the billboards on the ground reduce the amount of current generated by the thin-film solar cells due to the reduction of sunlight radiation, and reduce the flow of electricity to the billboards. The amount of power supplied to the display on the screen, thus affecting the effectiveness of the advertisement
