Guide: Solar lights are becoming more and more popular nowadays, and the emergence of solar floodlights has made environmental protection useless electricity a reality. Outdoor solar lights now have solar garden lights and solar lawn lights. The price of solar lights is also very affordable.

What is the solar energy used in solar lights?

When talking about solar lights, we will wonder where the solar energy comes from. Some people think it is a new energy source. Actually, from the birth of the earth, the earth has not left the sun and left without the life. Through solar energy; human beings are no exception. Eating, drinking, growing, and developing are inseparable from solar energy. It is solar energy that gives people life. Without solar energy, how can there be earth today? Without solar energy, how can there be life? Without solar energy, there will be a human sun rising from the east and falling from the west. It brings not only the light, the warmth, the change of the four seasons and the day and night, but also the cultivation of everything. It causes wind, rain, thunder and electricity in the atmosphere, and it also provides everything needed for life. Wind, water, and ocean on earth

Temperature difference energy, wave energy and biomass energy, and some tidal energy are all derived from the sun. Strictly speaking, they are all solar energy, a variant of solar energy, and another form of solar energy; even fossil fuels on the earth (such as Coal, oil, natural gas, etc. are fundamentally solar energy stored since ancient times, so the scope of solar energy in a broad sense is very large. But now it refers to the narrowly defined solar energy, which is limited to the direct conversion of solar thermal energy to photothermal, optoelectronic and photochemical. Solar energy is both primary energy and renewable energy. It is rich in resources and can be used free of charge without transportation and without any pollution to the environment.

What is the structure of the sun? What are the resources of solar energy available for solar lights?

       To understand solar energy, we must first understand the structure of the sun. The sun is the closest star to the Earth. Simply put, the sun is a hot, gas ball. Its diameter is about 139 × 10km, which is 109 times the diameter of the Earth. Its volume is 1.3 million times that of the Earth, and its mass is 330,000 times that of the Earth. Therefore, its density is only 1/4 of that of the Earth. The sun can usually be divided into two parts: the inner sphere and the solar atmosphere. The outer layer of the inner sphere is the fluid region in the convection; the solar atmosphere is divided into two layers, and the bottom layer is called the light sphere, which is the part that people can usually see. Above it is a chromosphere layer with a thickness of several thousand kilometers, and the outermost layer is a layer of corrugated with a small density. Its shape is irregular and often changes. From the center of the sun to the average radius of 1/4, the total mass is 40%, the temperature is up to 1500×10°C, the density is over 1009g/cm3, and at 70% of the average radius, the temperature is reduced to 50×104°C. In the outer troposphere, the temperature is further reduced to about 6000 ° C, and the density is reduced to 0.01 gg / cm. The main components of the sun are hydrogen and nitrogen, of which about 78% of hydrogen and about 20% of nitrogen. Under abnormally high temperatures and high pressures, atoms lose all or most of the extranuclear electrons, and they undergo multiple nuclear reactions during high-speed motion and collision. The most important of these is the reaction of hydrogen polymerization into a nitrogen nucleus called a thermonuclear reaction. According to Einstein's theory of relativity, mass can be converted into energy through thermonuclear reaction. The formula is: Emmet, where m is the mass of matter; c is the speed of light in vacuum (3 × 10 °m / s). More than 600 million tons of hydrogen are converted to nitrogen and generate a lot of energy. These energies are emitted, and the total power is equivalent to 3.8×10mMW. Although the sun's transmitting power is so huge, the quality of the sun is too large, and it can still be maintained for several billion years.

      So we don't have to worry about the exhaustion of solar energy. The current solar energy development is also very rapid. The conversion efficiency, utilization rate and penetration rate of solar energy are still the focus of our concern. The research and development of solar lights such as solar garden lights and solar lawn lights are more and more in line with the people's living needs and political environmental protection.

      nuusolar  will continue to develop cost-effective solar lights for the needs of the people!
