Air density is the mass of air per unit volume in kilograms per cubic meter (kg/m3). The air density decreases rapidly with height, and the ground density at the lowest level is the highest, and the thinner it becomes. If the height at which the smallest particles in the atmosphere are balanced with the centrifugal force of the earth's rotation is taken as the upper boundary of the atmosphere, then this height is about 42,000 km from the Earth. However, satellite measurements have shown that, at heights of several thousand kilometers, it is mainly replaced by particles from the solar atmosphere. Therefore, the equilibrium height cannot be defined as the upper boundary of the atmosphere.
Because the solar wind (the sun's high-temperature expansion and the particle stream that is thrown outwards as the solar wind) enters the earth’s magnetic field, it enters Earth’s magnetic field and collides with atoms in the earth’s atmosphere at an altitude of 200-1200 km, forming an auroral phenomenon. The atmosphere exists, so meteorology defines the atmosphere as 3000 kilometers.
In fact, this is not important for us to study wind power. We are concerned about the situation below the atmospheric troposphere. The troposphere is about 12 kilometers high. This layer of air molecules is dense and accounts for 80% of the total atmospheric weight. This layer, which is hundreds of meters to 1,500 meters in the troposphere and is called the atmospheric boundary layer, is also known as the friction layer. In this layer, the atmospheric motion is basically in an irregular turbulent state. Due to the different influences of the ground heat and power, a strong exchange of various attributes of the atmosphere and the surface is formed. Therefore, the distribution of the wind, temperature, etc. in the boundary layer has a special variation pattern. This layer is our most concerned layer.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
